The difference between casement hinges and mother-child hinges Five differences between mother-child hinges and flat hingesA hinge is a metal material that connects two parts of an object and enables it to move. It is often used for the installation of doors, windows, and cabinet doors. It is the iron sheet that fixes the door in our home. The hinges of doors on the market generally have Two types: casement hinge and mother-to-child hinge. So in terms of aesthetics and installation convenience, which is better, casement hinge or mother-to-child hinge? What is the difference between the two? Let the editor tell you Talk about the difference between the flat hinge and the mother-child hinge. I hope you can use it as a reference when purchasing.The five major differences between mother-child hinges and flat hingesstrong aestheticsJudging from the design of the mother-child hinge, it still has a certain difference from the casement hinge. It does not use a slotted design, which can relatively reduce damage to the door and greatly improve the overall aesthetics. It is now a home Ideal hardware use in life, widely used.thegood applicabilityThere is still an obvious difference between the mother-child hinge and the casement hinge, which has been greatly improved in design, so that the use of the hinge itself is better. The mother-child hinge takes into account the load-bearing capacity of the door, so that The slotted design increases the integrity of the door and makes its own scope of application wider, which is in line with the applicability of different doors and has a wide range of applications.theGood simplicityThe design of the mother-child hinge takes into account the actual decoration needs, and compared with the casement hinge, it also has a good guarantee in terms of simplicity. The mother-child hinge itself is designed taking into account the needs of convenient installation. In actual processing It is relatively easy and has become a widely used hardware product.thestrong designThe overall design of the mother-child hinge is stronger than that of the casement hinge, and it also pays more attention to practicality and firmness in the overall appearance design. As a commonly used hardware now, the mother-child hinge is the most important part of the connection and installation of doors and windows. The practical effect is obvious, and the installation position can be determined according to the size of the door gap without damaging the overall appearance.thepoor durabilityHowever, compared with the casement hinge, the mother-child hinge has many advantages, but it also has its own disadvantages, that is, poor durability. The length of the mother-child hinge itself is the same as that of ordinary hinges, but its inside and outside The design connection is not as good as the casement hinge, so the durability is poor. The casement hinge uses four middle rings, while the mother and child hinge has only two, so the performance is slightly inferior.After reading the introduction of the editor, I believe that everyone has a general understanding of the advantages and disadvantages of the casement hinge and the parent-child hinge. It looks beautiful; although the swing hinge is troublesome to install, it is durable, and it has relatively high technical requirements. You can choose the appropriate hinge according to the situation of your own door. Finally, the editor reminds everyone to choose the swing hinge The page must match the height and width of the slot.What are the special functions of mother-child hinges and ordinary flat hinges?When the hinges of the mother and child are closed, they are single-sided thickness, and the closed double-layer thickness of the flat opening. The difference is that when installed on the door, the hinges of the mother and child do not need to be slotted, and they can be directly nailed to the door. For the side-opening door, a groove should be made on the side of the door, and one side of the hinge should be embedded in the groove. This is the difference. The advantage of the mother-in-law is that it is easy to install. The disadvantage is that the bearing capacity is not as good as that of the side-opening door. The advantage of the side-opening is that Good bearing capacity, after all, the force on both sides of the trench is even. Generally, three pieces are installed for the mother and child, and two pieces that are opened flat are enough.When installing a wooden door, should you choose a mother hinge or a normal hinge? Which brand is better?In terms of the convenience of use and the adaptability to the door, the mother-in-law hinge undoubtedly has the absolute upper hand. Its biggest selling point is its ease of use, because it does not require slotting compared with the installation of the flat hinge, which directly reduces the number of doors facing. The damage of the door greatly enhances the beauty of the door. More importantly, some non-solid wood doors (composite materials) or hollow wooden doors can't bear the slotting at all, and they are barely slotted to install the side-opening type. After a period of time, There may be serious quality problems such as door leaf falling off and door leaf perforation, but the unique design of the factor mother hinge can be installed directly without slotting, which enhances the integrity of the door and greatly enhances the applicability of the hinge to various types of inner doors.In terms of durability, the casement hinge is better, because the length of the mother and child hinges is the same as that of the ordinary hinge, but the inner and outer pieces of the mother and mother hinges should be overlapped, so that The inner page shrinks, while the outer page is hollowed out. From this point of view, the durability is definitely not as good as the casement hinge with two complete pages. In addition, the rotation and load-bearing often depend on the middle ring, and the wear resistance of the middle ring The degree of closure and the degree of closure of the central axis directly determine the load bearing. The casement hinge usually has 4 middle rings, and the mother and child have two rings. From this point of view, the durability of the mother and child hinge is worse than that of the casement hinge. reason.Is it better to use a mother-child hinge or a normal hinge?Mother-child hinges are better than ordinary hingesThe mother-child hinge is a hinge installed on the interior door. The mother-child hinge is an image title. The reason why it was so called at that time was because of the special structure of the hinge, which consisted of two pieces inside and outside. , like a mother and child, very vivid, so it is called a mother-child hinge.Ordinary hinges: used for cabinet doors, windows, doors, etc. The materials are iron, copper and stainless steel. The disadvantage of ordinary hinges is that they do not have the function of spring hinges. After the hinges are installed, various touch beads must be installed. , otherwise the wind will blow the door panel.In terms of durability, ordinary hinges are better than mother-child hinges, because the length of mother-child hinges is the same as that of ordinary hinges, but the inner and outer pieces of the mother-child hinge must overlap As a result, the inner page is shrunk, while the outer page is hollowed out. From this point of view, the durability is definitely not as good as that of an ordinary hinge with two complete pages. In addition, the rotation and load-bearing of the hinge often depend on the The middle ring, the degree of wear resistance of the middle ring and the degree of closure of the central axis directly determine the load bearing of the hinge. There are usually 4 middle rings in the casement hinge, and there are two mother and child hinges. From this point of view, it is also a mother and child hinge. The reason why the durability is worse than ordinary hinges. From the convenience of use and the adaptability to the door, the mother-child hinge undoubtedly has the absolute upper hand. The biggest selling point of the mother-child hinge is that it is easy to use, because it is relatively The installation of ordinary hinges does not require slotting, which directly reduces the damage to the door and greatly enhances the appearance of the door. More importantly, some non-solid wood doors (composite materials) or hollow wooden doors cannot withstand slotting at all. , a barely slotted loadedOrdinary hinges, after a period of time, may have serious quality problems such as door leaf falling off and door leaf perforation. However, the unique design of factor mother hinges can be installed directly without slotting, which enhances the integrity of the door and greatly enhances the hinge. Applicability to various types of interior doors.thetheThe difference between mother and child hinges and ordinary hingesDifference: When installed on the door, the mother-in-law hinge does not need to be slotted, it can be directly nailed to the door, while the ordinary hinge needs to be placed on the edge of the door.Side slots place one side of the hinge in the slot.The advantage of the mother and child hinge is that it is easy to install, but the disadvantage is that the bearing capacity is not as good as that of the flat hinge, and the advantage of the hinge is that it has a good bearing capacity.The force on both sides of the groove is even. Generally, three pieces are installed for the mother and child, and two pieces for ordinary hinges are enough.Ordinary hingeUsed for cabinet doors, windows, doors, etc. The materials are iron, copper and stainless steel. Ordinary hinges do not have the function of spring hinges.After installing the hinge, you must install all kinds of touch beads, otherwise the wind will blow the door panel.Mother and Child HingeIt is a kind of hinge installed on the interior door. The mother-child hinge is a kind of image title. The reason why it was called so at that time was because of thisThe special structure of this kind of hinge is composed of two pieces inside and outside, just like a mother and a child. It is very vivid, so it is called a mother-child hinge.Advantages and Disadvantages1. In terms of durability, casement hinges are better than mother-child hinges, because the length of mother-child hinges is the same as that of ordinary hingesYes, but the inner piece and the outer piece of the factor mother hinge should achieve the effect of overlapping, so that the inner piece page is reduced, and the outer piece is hollowed out.2. From this point of view, the durability is definitely not as good as the casement hinge with two complete pages, and the rotation and load-bearing of the hinge are a lotThe time depends on the middle ring. The degree of wear resistance of the middle ring and the degree of closure of the central shaft directly determine the load bearing of the hinge.There are 4 middle rings, and there are two mother and child hinges. From this point of view, it is also the reason why the durability of the mother and child hinges is worse than that of the casement hinges.3. In terms of the convenience of use and the adaptability to the door, the mother-child hinge undoubtedly has the absolute upper hand. The biggest selling point of the mother-child hingeIt is easy to use, because it does not need to be slotted compared with the installation of the flat hinge, which directly reduces the damage to the door and greatly enhances theThe beauty of the door.4. More importantly, some non-solid wood doors (composite materials) or hollow wooden doors cannot withstand slotting at all, and they are barely opened.Slot-mounted hinges, after a period of time, there may be serious quality problems such as door leaf falling off, door leaf perforation, etc.The unique design of the hinge can be directly installed without slotting, which enhances the integrity of the door and greatly enhances the hinge for various types of inner doors.applicability.Points for attention when installing the hinge1. Before installation, check whether the hinges match the door and window frames and leaves.2. Check whether the hinge groove matches the height, width and thickness of the hinge.3. Check whether the hinge and the screws and fasteners connected to it are matched.4. The connection method of the hinge should match the material of the frame and fan. For example, the hinge used for the steel frame wooden door, the side connected to the steel frame is welded.The side connected with the wooden door leaf is fixed with wood screws.5. When the two leaf plates of the hinge are asymmetrical, it should be identified which leaf plate should be connected to the fan and which leaf plate should be connected to the door and window frame.The side connected to the three sections of the shaft should be fixed to the frame, and the side connected to the two sections of the shaft should be fixed to the doors and windows. When installing, ensure that the sameThe shafts of the hinges on one leaf are on the same vertical line to prevent the door and window leaves from springing up.Which one is better for mother-child hinges and flat hinges?It is better to open the hinges sideways, and the letters are reversed, so you can read them up and down.There are holes on both the child leaf and the mother leaf, and the door leaf and the door frame can be fixed by installing screws and achieve normal opening and closing. The mother and child hinges are suitable for installation in the center, depth and edge of the door frame.There is no need to remove the fixed hinge (slot) of the door leaf like the casement hinge. The size of the gap between the door frame and the door leaf is reasonable, and the overall aesthetic effect is not damaged. The installation is quick and convenient. The price of the mother and child hinge is only 3 of the ordinary hinge. /5, because of the above characteristics, it is more and more favored by consumers.Advantages and disadvantages of mother and child hinges:In terms of the convenience of use and the adaptability to the door, the mother-child hinge undoubtedly has the absolute upper hand. The biggest selling point of the mother-child hinge is its ease of use, because it does not require slotting compared with the installation of the casement hinge. It directly reduces the damage to the door and greatly enhances the beauty of the door.Nowadays, some non-solid wood doors (composite materials) or hollow wooden doors cannot withstand slotting at all, and they are barely slotted to install flat hinges. After a period of time, serious quality problems such as door leaf falling off and door leaf perforation may occur. The unique design of the factor mother hinge can be directly installed without slotting, which enhances the integrity of the door and greatly enhances the applicability of the hinge to various types of inner doors.Refer to the above content: parent-child hingeWhat is the difference between mother-child hinge and flat hinge? What is the difference between mother-child hinge and flat hinge?In fact, when it comes to mother-child hinges and flat-opening hinges, many people don't know what these two products are, because people really rarely come into contact with mother-child hinges and flat-opening hinges in their lives. The product is actually a tool installed on the interior door to help the door open and close. The decoration master will install the mother-in-law hinge and the flat hinge during the installation of the interior door. You don't need to care about this project, but you can Learn about these two hinges, and today we will introduce them to you.What is a mother-child hingeThe image of the mother-child hinge is a hinge installed on the interior door. It includes the hinge piece and the hinge shaft. Its main feature is that the hinge piece is divided into a child hinge and a mother hinge. Both the hinge and the mother hinge are installed on the hinge shaft and form a hinge connection. Both the child hinge and the mother hinge can rotate freely around the hinge axis, and the leaves of the child hinge and the mother hinge are on the hinge. If the axes are in the same tangential direction, the child hinge and the mother hinge have holes, and the door leaf and the door frame can be fixed by installing screws and achieve normal opening and closing. The mother and child hinges are centered in the door frame. Both depth and edge are suitable for installation. It is not necessary to remove the fixed hinge (slot) of the door leaf like the casement hinge. The size of the gap between the door frame and the door leaf is reasonable, and the overall aesthetic effect is not damaged. The installation is quick and convenient. The price is only 3/5 of the ordinary hinge, because of the above characteristics, it is more and more favored by consumers.The difference between mother and child hinges and flat hingesWhen the hinges of the mother and child are closed, they are single-sided thickness, and the closed double-layer thickness of the flat opening. For the side-opening door, a groove should be made on the side of the door and one side of the hinge should be inserted into the groove. The bearing capacity is good, after all, the force on both sides of the groove is even. Generally, three pieces are installed for the mother and child, and two pieces for the flat opening are enough.theWhich is better, the mother-in-law hinge and the flat hinge?In fact, we can already see from the above introduction that if you need a hinge with better bearing capacity, you can choose a flat hinge. If you like a hinge that is easier to install, you can choose a mother hinge.In the above, we have introduced some information about mother-child hinges and open hinges. In this article, we mainly focus on the topic of who is better about mother-child hinges and open hinges. Yes, you can see that we have divided the content of the mother-child hinge and the flat-opening hinge into three parts to explain to you. First, we introduce the difference between the mother-child hinge and the flat-opening hinge. Which one is better, the female hinge and the flat hinge, you can find out.What is the best material for the door hingestainless steel or brass1. The hinge material generally has three materials: stainless steel, pure copper and iron. If it is installed at home, it is recommended that you choose 304 stainless steel, because the cost of pure copper is relatively high, and iron is easy to rust , compared with stainless steel hinges, it is both practical and cost-effective.2. Regarding how to choose the color of the hinges, electroplating technology is generally used now, and stainless steel materials will also have a variety of color options. We can choose the appropriate hinge color according to the different styles of doors and windows of our houses.3. There are two types of door hinges on the market: side hinges and mother-to-child hinges. The side hinges are what we call standard hinges. They generally require manual slotting during installation. It is recommended You can choose this kind of door, which is more practical and worry-free; the mother and child hinges are less stressed, and are suitable for relatively light PVC doors or hollow doors.The difference between casement hinges and mother-child hinges Key points for installation of casement hingesCasement hinges and mother-to-child hinges are two representative products of the hinge, so what is the difference between casement hinges and mother-to-child hinges? Which one is more reliable for mother-to-child hinges and flat hinges? What? Today, in addition to comparing and analyzing these two aspects of knowledge for you, we also give you the installation operation and precautions of the swing hinge. From the beginning, you can know that a suitable and reasonable swing hinge may be more durable. However, the mother-child hinge is easy to install, and its aesthetic performance is even better. However, both of them can serve the purpose of connection and consolidation. You can learn from the following comprehensively. What we will explain to you is the basic popularization information of these aspects. I believe the key Sometimes it can come in handy.the1. The difference between the casement hinge and the mother-child hingeWhen the hinges of the mother and child are closed, they are single-sided thickness, and the closed double-layer thickness of the flat opening. The difference is that when installed on the door, the hinges of the mother and child do not need to be slotted, and they can be directly nailed to the door. For the side-opening door, a groove should be made on the side of the door, and one side of the hinge should be embedded in the groove. This is the difference. The advantage of the mother-in-law is that it is easy to install. The disadvantage is that the bearing capacity is not as good as that of the side-opening door. The advantage of the side-opening is that Good bearing capacity, after all, the force on both sides of the trench is even. Generally, three pieces are installed for the mother and child, and two pieces that are opened flat are enough.the2. Which one is better for mother-child hinges and flat hinges?At present, the hinges on the market are mainly divided into two types: casement hinges and mother-in-law hinges. From the perspective of aesthetics and installation convenience, mother-in-law hinges are more convenient to install than side hinges. There is no need to slot on the wooden door, just use It can be installed with screws, and the aesthetics are better.But in terms of durability, the casement hinge is more durable than the mother-to-child hinge. When the casement hinge is installed, it needs to slot the door leaf fixed hinge, and the hinge is embedded in the groove. The overall bearing capacity of the hinge is The force is better than the mother-in-law hinge, and it is relatively more durable after a long time of use.It should be noted that the swing hinge has relatively high requirements on the material of the door and the technical level of the installation workers. If the door purchased by the owner is hollow, the swing hinge cannot be used because the door cannot be slotted. At the same time, workers are required to Be sure to pay more attention when slotting to avoid damaging the wooden door. In terms of purchase price, the flat hinge is slightly more expensive than the mother and child hinge, but the price difference between the two is not very big.the3. Key points for installation of casement hinges(1) Before installation, check whether the hinges match the door and window frames and leaves.(2) Check whether the hinge groove matches the height, width and thickness of the hinge.(3) It should be checked whether the hinges are compatible with the screws and fasteners connected to them.(4) The connection method of the hinge should match the material of the frame and leaf. For example, the hinge used for the steel frame wooden door, the side connected to the steel frame is welded, and the side connected to the wooden door leaf is fixed with wood screws.(5) When the two leaf plates of the hinge are asymmetrical, it should be identified which leaf plate should be connected to the fan, which leaf plate should be connected to the door and window frame, and the side connected to the three sections of the shaft should be connected to the frame. Fixed, the side connected with the two sections of the shaft should be fixed with the doors and windows.(6) When installing, it should be ensured that the axes of the hinges on the same leaf are on the same vertical line, so as to prevent the door and window leaves from springing up.What I recommend for you today is the description of two well-known and representative hinge products, including the respective advantages of the casement hinge and the parent-child hinge, as well as the selection precautions. The ability or the appearance is not the same, or the complexity of the steps in the decoration operation process is not the same. If you want to look at it from the perspective of firmness, reliability, and convenience, the flat hinge may be better, and it has beautiful performance, convenient operation, and long service life. It is also quite good, and is more suitable for the choice of modern and simple decoration style. For details, you can refer to the above to understand. What we will explain to you is the difference between the two and the purchase precautions.The difference between mother-child hinges and flat hinges Which one is better for mother-child hinges and flat hingesMother-child hinge.1. The beauty and installation convenience are different: the mother-in-law hinge is more convenient to install than the flat hinge. It does not need to slot on the wooden door, but only needs to be installed with screws, and the aesthetics is better.2. The durability is different: the casement hinge is more durable than the parent-child hinge. When the casement hinge is installed, it needs to slot the door leaf fixed hinge, and the hinge is embedded in the groove. The overall bearing capacity of the hinge It is better than mother-in-law hinges, and it is relatively more durable after a long time of use.Precautions for the use of mother and child hingesIt should be noted that unlike ordinary hinges, the mother-child hinge is not two plates of the same size, but looks like a pair of mother and child, consisting of a smaller child leaf and a larger mother leaf. The leaf is shaped like a hollowed out part of the mother leaf. Compared with ordinary hinges, the mother and child hinges are thinner and are not suitable for heavier wooden doors.It should be noted that the core of the hinge is the bearing. The flexibility and durability of the door opening and closing are determined by the bearing. The bearing of the mother and child hinge is lighter than the ordinary hinge. It is better to install three hinges. for better load bearing.The above content refers to mother-in-law hinges and swing doorsTallsen is always customer-oriented and devoted to offering the best products and service for each customer in an efficient manner.Tallsen has devoted to the development, manufacturing, marketing and sales of since its inception.We have been paying attention to producing finest and providing the most professional service.Hinge has a wide application, which is suitable for many scenes such as new product promotion, sales promotion, and exclusive agency display.With advanced welding, cutting, polishing, and other production technology supported and staff backed up, Tallsen promises flawless products and considerate service provided to customers.Leading R&D level: Our industry-leading R&D level has been achieved through continuous research and technological development, as well as by unleashing the creativity of our designers.Tallsen's are made of high-quality materials.

What are the door and window hardwareThere are many door and window hardware, the common ones are as follows:1. Hinges. Mainly made of iron, copper, stainless steel and other materials, divided into pipe hinges, door hinges, glass hinges, countertop hinges, flap door hinges, etc.2. Hinges. Mainly divided into two types: open hinges and concealed hinges. Open hinges are more common and are suitable for basically doors and windows, while concealed hinges are generally used on furniture doors. There are hydraulic, quick-installation and other types.3. Track. Whether it is a sliding door or a sliding window, a track is required. The composition of the track includes hanging wheels, glass pulleys, and track lights.4. Door and window locks. Mainly divided into single-safety door locks, double-safety door locks and triple-safety door locks. occasion use.5. Handle. The handle on the window is generally installed in the middle of the edge of the window sash, mainly made of brass, stainless steel, zinc alloy and other materials; the handle on the door has round handles, square handles, double row handles and other shapes, mainly including Low carbon steel, aluminum alloy, stainless steel and other materials.Broken bridge aluminum inner opening is a hidden hinge, what kind of hinge is better?Hiding the hinges is fine.Specifically, because aluminum alloy is a metal, it conducts heat faster, so when there is a large difference between indoor and outdoor temperatures, aluminum alloy can become a "bridge" for heat transfer. Such a material is made of doors and windows, and its heat insulation performance is not good. Good. The broken bridge aluminum is to disconnect the aluminum alloy from the middle. It uses hard plastic to connect the disconnected aluminum alloy. We know that the heat conduction of plastic is obviously slower than that of metal, so that the heat is not easy to pass through the whole material. , the heat insulation performance of the material will become better, which is the origin of the name "broken bridge aluminum (alloy)".sliding windowThe advantages of sliding windows are simple, beautiful, large window width, large glass block, wide field of vision, high lighting rate, convenient glass cleaning, flexible use, safety and reliability, long service life, opening in one plane, less space occupation, and convenient installation of screen windows etc. At present, the most widely used is the sliding window.Disadvantages: The two windows cannot be opened at the same time, at most they can only be opened halfway, and the ventilation is relatively poor; sometimes the sealing is also slightly poor.Sliding window: There are two types: left and right, up and down. Sliding windows have the advantages of not occupying indoor space, beautiful appearance, economical price, and good sealing. High-grade slide rails are used, which can be opened flexibly with a slight push. Glass not only increases indoor lighting, but also improves the overall appearance of the building. The window sashes are in a good stress state and are not easy to be damaged, but the ventilation area is limited to a certain extent.Window hardware classification of door and window hardware accessories One of the basic accessories of the casement window is the hinge. Due to the one-way opening nature of the hinge, the hinge is always installed in the opening direction, that is, the hinge of the inward opening window is installed indoors, and the hinge of the outward opening window is installed outdoors.In order not to let the hinge affect the sealing of the window, the hinge of the metal window is usually welded on the outside of the window profile. The lock of the outward opening window is a kind of rotating card lock, and the handle is usually combined with the lock. The lock of the ordinary inward opening window It can be a simple latch. The disadvantage of the latch is that it does not have the pressing function of the rotating card lock.The handle of the inward-opening window is independent and has no relationship with other parts. The limiter is an essential part of the outward-opening window to prevent the wind from blowing the sash and causing collision. However, the two hinges and the limiter are at three points The firmness of the fixed plane formed is limited, and the stopper with better quality is made of copper, the purpose is to prevent rust. From the formal point of view, the concept of inclination and casement window is a window that can be hung down and opened inward, but also can be opened inward. But this is far more than a special window opening method. In fact, it is a variety of window control functions. of synthesis.First of all, when this kind of window is tilted inward, the purpose is to ventilate. The top scissor connector acts as a stopper. When it is opened flat, the top scissor connector is also a hinge. The bottom hinge is also a supply Shaft for inclination. The purpose of inward opening is to clearly observe the scenery outside the window, and more importantly, it is easy to clean the glass. The reason why domestic low-end residential buildings rarely have clean and bright windows is that the window type does not consider cleaning the glass. .It can be said that the inward casement window is a comprehensive satisfaction for people. The hardware of the inward casement window includes top scissor connectors, upper corner connectors, locks, handles, connecting rods, multi-point locks, and lower corner connectors. It is also used as the bottom shaft of inclination window, and the bottom hinge is also the bottom shaft of internal rotation. This kind of hardware is suitable for wood, aluminum alloy and plastic steel windows.How to fix the connecting rod on the window sash? There are two solutions. The first is to design double sets of connecting rods, one of which is used for fixing and the other for interlocking locking points. The second is to pre-design sliding grooves on the window frame profiles. It is better than the first solution in terms of maintenance-free. The combination of glass curtain wall and window is a relatively difficult problem. The internationally advanced curtain wall system can make the inward and inward casement window a curtain wall unit similar to glass, so as to achieve the overall air tightness, water tightness and wind pressure resistance level of the curtain wall. The technical level and cost of doing so are very high. At present, very few domestic companies can reach this level.Since the load-bearing structure of the glass curtain wall is generally inside, outward opening windows are the easiest window opening solution. However, if hinges are used, the exposed hinges will destroy the integrity of the glass curtain wall, so there are four-link accessories. Four-link The rod is a substitute for the hinge, which uses the principle of variable area of the quadrilateral under the condition of constant side length to achieve the purpose of window opening.The four-linkage is fixed on the side of the window sash and the window frame. When the window is closed, the four-linkage is completely hidden in the window frame, which fundamentally solves the problem of exposed hinges. The only feature is the work of the four-linkage. The phenomenon determined by the principle, that is, when the sash is opened, the center of gravity of the sash will have an obvious settlement. This settlement can prevent the wind from closing the sash, but it brings a lot of inconvenience to the installation and use of the window opener. Large, the four-linkage bears the weight of the window sash for a long time, which will cause a certain drop, which will lead to the lax closing of the window sash.The use of multi-point locks is to increase the wind pressure resistance of the window. Multiple cylindrical lock points are connected on the window sash through connecting rods. Under the operation of rotating the handle, the lock points slide into the lock body fixed on the window frame. Through corner connectors, the four sides of the window can be locked with one, two or more locking points. The multi-point lock has completely changed the traditional system of locking windows. This link plus locking point scheme is also used to improve The security level of the door. 1. Manual window openerThe purpose of the manual window opener is to open the ventilation window with a higher position through a certain device. According to the principle of thermal effect of the air, the hot air and light harmful gas that should be removed can only be effectively removed through the window with a higher position. Manual window opening The device generally includes five parts: the execution part of the window (such as the scissors), the corner connector, the operating part, the connecting rod and the decorative cover. The execution part of the window determines the width of the window and the bearing capacity of the window. Weight and whether there is a locking function. The corner connector is a transmission part, and its deformation determines the ability of the window opener to adapt to different window types and different installation conditions. The operating part can be in the form of a handle or a rocker. The handle-type operating part Simple and low cost. The power output of the rocker-type operating parts is uniform, not easy to be damaged, the processing accuracy is high, and the cost is high. The manual window opener is suitable for bottom-hung inward-opening windows and top-hung outward-opening windows. Top-hung outward-opening windows It needs to be equipped with special outward opening accessories. From the analysis of the force of the window opener, the lower hanging inward opening window with the hinge at the bottom is more labor-saving. The upper hanging outward opening window with the hinge at the upper part is more laborious. Special attention must be paid to Use the four-link with caution, because the four-link accessory will cause a large settlement of the center of gravity of the window when the window is opened. If the weight of the window is heavy to a certain extent, the force of the window opener may not be enough to lift the window to close the window .2. Electric window openerThe simplest electric window opener is to match the actuator parts of the mechanical window opener with a drive motor and a switch. There are also rack and pinion type window openers and chain type window openers. But from the stability of the product In terms of service life requirements, the window opener needs to be dust-proof, moisture-proof or even waterproof. Dust accumulation will wear the window opener, moisture will cause the window opener to rust, and water will short-circuit the circuit of the window opener. The indoor relative humidity Condensation caused by changes is a frequent occurrence in buildings with poor thermal insulation performance of the windows or changes in the indoor environment, especially greenhouse buildings. Carry out a comprehensive and thorough analysis and understanding of the environmental conditions used by the window opener, and choose which window to open The window opener is very important. The fully enclosed dustproof, moisture-proof and waterproof window opener in the world has an internal screw type window opener.

Choose to open The window device must also pay attention to whether it is convenient to install, because the installation conditions on the construction site may be very limited.There are currently two types of automatic control systems for electric window openers. The greenhouse control system is based on the measured temperature, humidity, sunlight, wind intensity, and rain level values, and compares them with the preset values to open the window. Systems for window and window closing control.The automatic smoke and heat exhaust system is a newly developed fire protection concept in the world, that is, when a fire occurs and smoke and heat are generated, the windows used for smoke and heat exhaust are automatically opened. As modern buildings have increasingly comprehensive fire protection requirements for building materials, and Accurately define the fire performance of materials in terms of flame retardancy. Therefore, once a fire occurs, the smoke and the harmful substances contained in it will cause more direct damage to personnel. Or the harmful smoke hinders active life-saving behavior and passive escape behavior. From From the research on the development process of fire, it can be seen that in the initial stage of fire, a large amount of smoke and heat energy are first produced. The smoke rises due to the action of heat and gathers on the upper floor of the building. If the smoke and heat energy cannot be discharged quickly, the building The temperature in the building will rise quickly, which will intensify the fire. In addition, when a fire occurs, due to the large consumption of oxygen in the building, a strong negative pressure will be generated in the building, causing the building to collapse. The fact is that the building destroyed by the fire , except that there are explosive substances in the building, it usually collapses inward from the top. The design, construction and use of the automatic smoke and heat exhaust system are related to the curtain wall company or window production company, weak electricity, and fire control. The complexity is high, and the relevant national departments should conduct comprehensive evaluation and supervision on the qualifications, experience and after-sales service of the manufacturers providing the system to ensure the quality of the project. At present, some high-end buildings in our country have used this system.The opening method of the window is push-pull, inward opening and outward opening, which opening method is better and how to chooseMany friends do not fully consider too much when choosing windows, ignoring the window opening method of the window, which leads to many inconveniences in future life and home.
