   Gas spring is a kind of elastic element which can support, buffer, brake, height adjustment and angle adjustment function. The basic principle of the gas spring is to fill in a closed cylinder with a certain pressure of nitrogen and oil, or oil and gas mixture, and then use the role of the piston rod or piston pressure on the gas spring to produce thrust or tension, gas springs and machinery The biggest difference between the spring is that the force - displacement curve of the former is very small, and the force value remains constant throughout the whole movement. The latter has a large slope of the force - displacement curve. According to the structure and function of the gas spring, the gas spring mainly has the free type gas spring, the self-locking type gas spring, the free stop gas spring, the traction type gas spring and the damper several kinds.
   Free gas spring (compressed gas spring) only stretch (no external force, the longest length) and compression (external force is greater than the gas spring thrust, the shortest length) two states, in the trip can not stop, mainly from the support role, The gas spring has two kinds of structure: constant damping and variable damping. In the automotive, construction machinery, textile machinery, printing machinery, office furniture and other industries are widely used.
   Self-locking gas spring (lift can lock the gas spring, angle can lock the gas spring) through its internal valve can be locked in the air spring at any position, according to the internal structure of the different, the gas spring flexible locking, compression Rigid locking, tensile rigid locking, compression tensile biaxial rigid locking and other types. Self-locking gas spring at the same time with support, height and angle adjustment function, and easy operation and flexible, simple structure. And thus in medical equipment, furniture, automotive and other industries are widely used.
   Free air spring (balance gas spring) through its internal special balance valve mechanism, coupled with a reasonable external load design, the gas spring can stop at any position in the trip, but no additional locking force, its characteristics Between the free gas spring and the self-locking gas spring. Mainly used in kitchen furniture, medical equipment, electronic products and other industries.
   The traction gas spring (tension gas spring) is a special gas spring: the other gas springs are in the longest position in the free state, that is, after being subjected to external forces from the longest position to the shortest position , While the free state of the traction gas spring is in the shortest position and is traversed from the shortest to the longest. Traction gas spring also has a corresponding free type, self-locking and other products.
   The dampers can change the damping force with the speed of movement through the damping structure on the piston, and can significantly damp the speed of the connected mechanism, which has a variety of structures to suit different applications. In the car, home appliances, medical equipment are used more.
