Classification of gas springs

Classification of gas springs：

1.The free gas spring is the most widely used gas spring. It mainly plays a supporting role, with only the shortest and longest positions, and can not stop itself in the journey. It is widely used in automobile, textile machinery, printing equipment, office equipment, engineering machinery and other industries. Free air spring is widely used in automobile, engineering machinery, printing machinery, textile equipment and other industries because of its light, stable work, convenient operation and favorable price. Or cold environment, acid or alkaline environment, etc.

2. Self locking gas spring (angle adjuster, controllable gas spring) is the most widely used in medical devices. This kind of gas spring can stop at any position in the stroke with the aid of some release mechanisms, and has a great locking force (can reach more than 10000n) after stopping.

3. Random stop gas spring (friction gas spring, balance gas spring) is mainly used in kitchen furniture, medical equipment and other fields. Its characteristic lies between free gas spring and self-locking gas spring: it can stop at any position in the stroke without any external structure, but without additional locking force. Mainly through the controller (handle or cable) to achieve the effect. It can also be realized by the extension and contraction of the piston rod. When the controller is adjusted to stop at the desired position, the valve will close independently and the piston rod will lock at the required position. When the lock occurs, the lock can be realized. However, if the locking force is exceeded, the locking function will no longer be effective.

4. The air spring (air pressure bar) of swivel chair is mainly used in swivel chair to adjust the position. Its characteristics are controllable and large demand.

5. The gas traction spring is a kind of special gas spring: other gas springs are in the longest position when they are in the free state, that is, they move from the longest position to the shortest position when they are under the external force, while the free state of the traction gas spring moves from the shortest position when they are under the traction. There are also corresponding free type and self-locking type in traction air spring.

6.Damper is widely used in automobile and medical equipment. Its characteristic is that the resistance changes with the running speed. It can obviously buffer the speed of the connected mechanism. The damper is mainly used for buffering. Its biggest characteristic is that the force of the air spring changes with the change of the moving speed. When the action point of the force guiding the gas spring moves faster, the resistance of the spring increases obviously, but when the action point moves slowly, the resistance is almost No. The damper is mainly used in washing machine, refrigerator and other industries.
