What's the matter if the dredge machine can't clamp the spring?
hey-hey
only one answer
The triangular piece that catches the spring is worn out, replace it
At the beginning, the strength of the hand pressure is very small, and gradually, you must press hard or the range of the pressure hand is too large, that is, the triangular piece is worn out
A spring is an elastic element that works through its own large elastic deformation. It is widely used in various machines. Its main functions are:
1. Control the movement of machinery, such as the springs that control the opening and closing of cylinder valves in internal combustion engines, and the control springs in clutches;
2. Absorb vibration and impact energy, such as damping springs in various vehicles and springs of various buffers, etc.;
3. Store and release energy, such as clock springs, bolt springs, etc.;
4. Measure the size of the force, such as the spring in the spring balance and the dynamometer, etc.
Spring is a mechanical part that uses elasticity to work. Parts made of elastic materials are deformed under the action of external force, and then return to their original shape after removing the external force. It is also called "spring". It is generally made of spring steel. The types of springs are complex Various, according to the shape, there are mainly coil springs, scroll springs, leaf springs, special-shaped springs, etc.
Reverse the dredge, the movement of the thread is the same as the direction of unloading the screw. When turning, it looks like it is moving forward, and the dredge will come out slowly; the machine should be turned on, and stop for a second or two to confirm the spring Only when the bar is not stuck can it be started continuously.
The pipe dredger is a tool used to clean and dredge the sewer. There are steel wire type and pneumatic type. It is an indispensable tool in modern family life. When using it, you should pay attention to the power plug and avoid motor maintenance.
Torsion spring (torsion spring) uses the principle of leverage to twist or rotate the elastic material with soft material and high toughness to make it have great mechanical energy. It is a spring that withstands torsional deformation, and its working part is also the coil either close together or separately.
The end structure of the torsion spring is processed into various shapes of torsion arms, from single torsion to double torsion, and even the deformation of various torsion bars can be formed according to the design.
Extended information:
The spring deforms under the action of external force. After removing the external force, the spring can return to its state. Many tools and equipment are reset by using the property of spring. For example, the hinges of many building gates are equipped with return springs for people to enter and exit Finally, the door will automatically reset. People also use this function to make automatic umbrellas, automatic pencils and other supplies, which are very convenient. In addition, various buttons and keys are also indispensable for return springs.
Utilize the rebound force (tension) after stretching to work to control the movement of parts, store energy, measure the size of force, etc. It is widely used in machines and instruments. The hooks are in the form of side hook extension springs and long hooks. Extension springs, English hook extension springs, German hook extension springs, semicircular hook extension springs, duckbill hook extension springs, etc. The materials include stainless steel, piano steel, high carbon steel, phosphor bronze, oil tempered alloy spring steel, etc. .

spring
Spring is a mechanical part that uses elasticity to work. It is generally made of spring steel. It is used to control the movement of parts, alleviate shock or vibration, store energy, measure force, etc., and is widely used in machines and instruments. The types of springs are complex and diverse, divided by shape, mainly coil springs, scroll springs, leaf springs, etc.
its main function
Control the movement of machinery, such as valve springs in internal combustion engines, control springs in clutches, etc. Absorb vibration and impact energy, such as buffer springs under automobiles and train carriages, vibration-absorbing springs in couplings, etc. Storage and output Energy is used as power, such as clock springs, springs in firearms, etc. Used as force-measuring elements, such as dynamometers, springs in spring scales, etc. The ratio of spring load to deformation is called spring stiffness, and the greater the stiffness, the spring harder.
According to the nature of the force, the spring can be divided into tension spring, compression spring, torsion spring and bending spring, and can be divided into disc spring, ring spring, plate spring, coil spring, truncated cone scroll spring and torsion bar spring according to the shape. .Ordinary cylindrical springs are the most widely used because they are simple to manufacture and can be made into various types according to the loading conditions. Heat treatment performance, etc., commonly used carbon spring steel, alloy spring steel, stainless spring steel, copper alloy, nickel alloy and rubber, etc. Spring manufacturing methods include cold rolling method and hot rolling method. Spring wire diameter less than 8 mm Generally, the cold rolling method is used, and the hot rolling method is used for those larger than 8 mm. Some springs are also subjected to strong pressure or shot blasting after they are made, which can improve the bearing capacity of the spring.
Spring is a kind of elastic element widely used in mechanical and electronic industries. The spring can produce large elastic deformation when it is loaded, and convert mechanical work or kinetic energy into deformation energy. After unloading, the deformation of the spring disappears and returns to its original shape. The deformation energy is converted into mechanical work or kinetic energy.

What is a Coil Spring?
The coil spring is a torsion spring, which is a spring that withstands torsional deformation. Its working part is also tightly wound into a spiral shape. The end structure of the torsion spring is a torsion arm processed into various shapes, not a hook ring. Torsion springs are often used in machinery The balance mechanism in it is widely used in industrial production such as automobiles, machine tools, and electrical appliances.
What is a tension spring?
Tension spring is a helical spring that bears axial tension. Tension springs are generally made of circular cross-section materials. When not under load, the coils of the tension spring are generally tight and there is no gap.
What is a Compression Spring?
The compression spring is a helical spring that bears the pressure. The cross-section of the material used is mostly circular, and it is also made of rectangular and multi-strand steel coils. The spring is generally of equal pitch. The shapes of the compression spring are: cylindrical, conical Shape, convex shape and concave shape and a small amount of non-circular, etc., there is a certain gap between the rings of the compression spring, when the spring is subjected to an external load, the spring shrinks and deforms, and stores deformation energy.
What is a torsion spring? The torsion spring uses the principle of leverage to twist or rotate the elastic material with soft material and high toughness, so that it has great mechanical energy.
The spring of the dredger is used to dredge the sewer. When using it, you must wear gloves, insert the wire head into the drain of the toilet, and insert it with your hands until it does not go in. Only by entering the elbow first so that the spring cannot be returned can it be changed. Good work.
Now the toilet is unclogged, and the spring cannot get in. This may be due to some performance reasons, so it should not be able to get in, so this should have a certain influence.
The lifting devices used in the lift chairs on the market are divided into 3 categories - oil pressure, mechanical and pneumatic. Most of the low-end lift chairs are pneumatic. There is a cylinder in the pneumatic lift chair, and the piston in the cylinder is pneumatic. The up and down movement of the rod controls the lifting of the chair. Regular manufacturers use nitrogen filling, the concentration is generally above 99%, and the pressure is about one or two atmospheres.
The lifting part has the following characteristics:
When pressing the lift valve switch:
When a person sits on it, that is, puts pressure on the lifting shaft, and the lifting shaft will descend smoothly with a uniform speed and can be lowered to the lowest point.
If no external force is applied to the lifting shaft, the lifting shaft will bounce back to the highest point immediately, and the speed is slightly faster, less than one second.
When not pressing (or releasing halfway through) the valve switch:
The lift shaft remains in its current position, neither compression nor tension can move it relative to the outer sleeve.
First understand the simpler free style gas spring:
The free-style gas spring is relatively simple and consists of three parts: a closed cylinder, a piston in the cylinder, and a piston rod extending outside. The air pressure inside the cylinder is greater than the atmospheric pressure outside, and there are small holes on both sides of the piston inside the cylinder. According to the knowledge of high school physics, if the piston rod is pressed inward, the resistance is constant, which is the difference between the air pressure at both ends of the piston rod.
The self-locking type means that a shaft is added to the piston rod of the free type, and the innermost end of the shaft is connected to a valve. This valve is used to control the communication hole of the piston part. When the valve is pressed down, there is a communication hole, which is equivalent to a free type; When the valve pops up, if there is no communication hole, it will be locked.
Here: the cylinder is our outer sleeve; the piston is our lifting shaft; the shaft inside the piston is our valve button switch.
Therefore, for this kind of chair, the air pressure in the sleeve is basically constant when no one is sitting. Look, as a metaphor, most of the shells of the grenade are relatively strong and have not burst, and the grenade handle is pushed out).

How to install the spring hinge
The spring hinge supports two states of fully open and fully closed, and it will automatically close in the middle state. If you want the door to reset to closed, after installing the spring hinge, what state will it be opened to by people passing by? It can be automatically reset to the closed state. And it is push-pull bidirectional. The spring hinge is mainly used for cabinet doors and wardrobe doors. It generally requires a plate thickness of 18-20mm. From the material, it can be divided into: galvanized iron, zinc alloy. In terms of performance, it can be divided into two types: holes need to be drilled and holes need not be drilled. No holes are called bridge hinges. Bridge hinges look like a bridge, so they are commonly called bridge hinges. How to install it?
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. 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 leaf, such as 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 fixed to the frame , the side connected to the two sections of the shaft should be fixed to the frame.
6. When installing, it should be ensured that the shafts 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.
