What are the advantages of damping hinges

Damping hinges, also known as buffer hinges, hydraulic hinges, rely on a brand-new technology to adapt to the closing speed of the door. The product uses hydraulic buffer technology to make the door open slowly when the opening is not greater than 60, which can reduce the impact. Force, forming a comfortable effect when closing, even if the door is closed with force, it will make the door close gently; ensure perfect and soft movement. Prevent children from pinching and so on! !

What is the difference between big bend, medium bend and straight bend of damping hinge, and how to distinguish

1. The gap is different: there is a gap between the two big bends of the hinge. There is a required minimum gap between the middle bends of the hinge.

2. The hinges are different: the middle bend of the hinge requires the use of a hinge with a curved hinge arm. The straight bend of the hinge requires the use of a hinge with a very curved hinge arm.

3. The position is different: the door panels with large curved hinges all cover the side panels of the cabinet. The two doors bent in the middle of the hinge share a side panel. The door with straight curved hinges is located in the cabinet, next to the side panel of the cabinet.

Selection skills of damping hinges:

Appearance is very basic. When purchasing, check how smooth the surface material of the damping hinge is. If there are problems such as scratches and deformation, do not choose it. These are generally produced by secondary processing of waste materials. , not only the appearance is ugly, no grade, the quality is not guaranteed.

The most important thing about the hinge is the switching function, and the damping hinge is a hydraulic hinge, which has higher requirements for the switch. You can check the damper, rivet assembly, etc., and also check whether there is noise when opening and closing, whether the turning speed is uniform, etc. , even if there are some small problems, it is not good.

Usually the hinges are equipped with screws, these are adjustment screws, which can be used to adjust the hinge in three dimensions up and down, front and back, left and right. When we buy damped hinges, we can use a screwdriver to adjust the screws three to four times, and then remove the screws to see the hinge arm Whether the thread on the thread is damaged, thread on thread is relatively easy to wear, and if the thread on the thread is not accurate enough, it is easy to slip and cannot be twisted.

damping hinge

called the hinge;

Hinges, also known as hinges, are mechanical devices used to connect two solids and allow relative rotation between them. Hinges can be composed of movable components or foldable materials. Hinges are mainly installed on doors and windows, The hinges are more installed on the cabinets. According to the material classification, they are mainly divided into stainless steel hinges and iron hinges; in order to let people enjoy better, hydraulic hinges (also known as damping hinges) have appeared. It has a buffer function, which minimizes the noise caused by the collision with the cabinet when the cabinet door is closed.

common classification

1. According to the type of base, it can be divided into detachable type and fixed type;

2. According to the type of arm body, it is divided into two types: slide-in type and snap-in type;

3. According to the cover position of the door panel, it is divided into full cover (straight bend, straight arm) with a general cover of 18%, and a half cover (medium bend, curved arm) with a cover of 9%. The built-in (large bend, large bend) door panels are all hidden inside;

4. According to the development stage of the hinge, it is divided into: one-stage force hinge, two-stage force hinge, hydraulic buffer hinge, touch self-opening hinge, etc.;

5. According to the opening angle of the hinge: generally 95-110 degrees are commonly used, and special ones are 25 degrees, 30 degrees, 45 degrees, 135 degrees, 165 degrees, 180 degrees, etc.;

How to distinguish between damping hinges and ordinary hinges

Damping hinge is a kind of hinge, also known as hydraulic hinge, which relies on hydraulic damper to adjust the closing speed of the door. Even if the door is closed with force, it will close gently, ensuring perfect and soft movement.

The overall structure of the damping hinge includes a support, a door box, a buffer, a connecting block, a connecting rod and a torsion spring. One end of the buffer is hinged on the support; the middle of the connecting block is hinged on the support, one side is hinged with the door box, and the other It is hinged with the piston rod of the buffer; the connecting block, connecting rod, support, and door box form a four-bar linkage; the buffer includes a piston rod, a housing, and a piston, and there are through holes and holes on the piston, and the piston rod When the piston is driven to move, the liquid can flow from one side to the other through the through hole, thus playing a buffering role.

The biggest difference between damped hinges and ordinary hinges is that a damper (usually a small cylinder) is added to the hinge.

How to choose the damping hinge correctly

Damping hinge selection basis:

1: Determine the damping force of the selected hinge according to the required damping force of the door

2: Select the hinge shape, opening angle, material, color, service life, damping breakpoint, etc. according to the working conditions.

3: Select the hinge type according to the interior door and exterior door

Real life common ball hinge principle

Hinges, also known as hinges, are mechanical devices used to connect two solids and allow rotation between them. Hinges may be composed of movable components or foldable materials. Hinges are mainly installed on doors and windows, while Hinges are more installed on cabinets. According to the classification of materials, they are mainly divided into stainless steel hinges and iron hinges; in order to let people enjoy better, hydraulic hinges (also known as damping hinges) have appeared. The buffer function minimizes the noise from the collision with the cabinet when the cabinet door is closed.

Working principle: The rotating pair composed of a cylindrical pin, a hole and its two ends is called a hinge. An object A is set on a part C of another object B. The movement of object A is limited by C, but A can revolve around C in Objects A and B form a hinge when they rotate in a plane or in space (C is spherical).

What is the working principle of the damper

working principle:

The main part of the damper is two counterweight objects each weighing about 150 tons suspended by steel cables, suspended on the 90th floor (395 meters). When strong winds hit, the device uses sensors to detect wind force and building The shaking degree of the object, and the computer controls the counterweight object to move in the opposite direction through the spring and hydraulic device, thereby reducing the shaking degree of the building.

Its working principle is like a person on a rocking boat, moving his body in the opposite direction of the boat's shaking to achieve balance. If a strong wind blows from the north, the counterweight is like a huge "pendulum" swinging to the north, making the The wind damper will generate a force that is opposite to the wind direction, thereby defusing the degree of shaking of the building and counteracting the impact of strong winds on the building.

After using this device, the acceleration of the strong wind on the building can be reduced by about 40%, so that even if it is hit by a strong wind, the people in the building will basically not feel the shaking of the building.

Classification:

The damper is just a component. It has different damping effects when used in different places or in different working environments. Damper: used for vibration reduction; Snubber: used for shock resistance, allowing movement at low speeds, locking when the speed or acceleration exceeds the corresponding value, form a rigid support.

Various applications are: spring dampers, pulse dampers, rotary dampers, wind dampers, viscous dampers, damped hinges, damped slide rails, furniture hardware, cabinet hardware, etc.

Scope of application:

Hydraulic dampers are mainly suitable for anti-vibration of pipelines and equipment in nuclear power plants, thermal power plants, chemical plants, steel plants, etc. They are often used to control impact fluid vibrations (such as rapid closing of the main valve, discharge of safety valves, water hammer, breaking The vibration of the piping system stimulated by the impact of pipes, etc.) and earthquakes; the liquid damper cannot effectively control the low-amplitude high-frequency or high-amplitude low-frequency vibration, and the spring damper is suitable for this occasion.

What is the principle of the slow-down of the damping of the toilet seat? !

When the toilet falls, it drives the rotating shaft to rotate, and squeezes the damping oil from the direction of the large hole to the direction of the small hole through the screw. It is generally used when the cover plate is heavy, and it is filled with a certain amount of damping oil. There is a rotating shaft in the middle, and the rotating shaft is processed into Spiral, discharged from the direction of the small hole, so it can only be discharged slowly, so as to realize the function of slow down of the toilet.

Damping helps reduce the resonance amplitude of the mechanical structure, thereby avoiding structural damage due to the vibration stress reaching the limit; damping helps the mechanical system quickly return to a stable state after being subjected to an instantaneous impact.

Damping helps to reduce the sound radiation caused by mechanical vibration and reduce mechanical noise. The noise of many mechanical components, such as the housing of transportation vehicles and saw blades, is mainly caused by vibration. The use of damping can effectively suppress resonance. thereby reducing noise.

Extended information:

When = 1, the solution is a pair of heavy real roots, and the damping form of the system at this time is called critical damping. In real life, the doors of many rooms or bathrooms in many buildings are equipped with torsion springs for automatic door closing. The floor is equipped with damping hinges, so that the damping of the door is close to the critical damping, so that when people close the door or the door is blown by the wind, it will not cause too much noise.

In actual vibration, since the frictional force always exists, the energy initially obtained by the vibration system will continue to perform negative work on the system due to the resistance during the vibration process, so that the energy of the system will continue to decrease, the intensity of the vibration will gradually weaken, and the amplitude will also decrease. It becomes smaller and smaller, so that the vibration finally stops, and the mechanical energy of the system like this is gradually reduced due to friction and conversion into internal energy, and the amplitude of the vibration weakens with time.

It is a combination of advanced hydraulic buffer system, unique transmission system (patented), high-performance manganese steel elastic system The advanced technology is integrated in the hinge, which can make the cabinet door close automatically and slowly, and can truly achieve the functions of cushioning, anti-collision, and noise reduction.

Extended information

A formed hydraulic hinge is composed of many parts, and these parts are all stamped out by molds. The raw material is 304 stainless steel, but the stamping molds are all iron, which will generate mechanical magnetism during processing.

Moreover, the fittings in the hinge are made of stainless iron, which also has suction through 304. The main parts are all pure 304, and the other small parts are made of stainless steel. It is easy to break, so it will definitely be sucked directly with a magnet, which is a normal phenomenon.
