The structure and working principle of gas spring

Gas spring is a kind of accessory that can support, buffer, brake, height adjustment and angle adjustment. At present, this product in the medical equipment, automobile, furniture, textile equipment, processing industry and other fields have been widely used. According to different characteristics and application areas, gas springs are also known as support rods, adjusters, gas pressure rods, dampers and so on. The basic principle of gas springs is to press an inert gas and oil, or an oil-air mixture, into a closed chamber. According to the structure and function of gas springs, gas springs are mainly free-type gas springs, self-locking gas springs, stop at will gas springs, traction gas springs, damper several kinds.

I. Free-type gas spring (support rod) is the most widely used gas spring. It mainly plays a supporting role, only the shortest, longest two positions, in the stroke can not stop by itself. In the automobile, textile machinery, printing equipment, office equipment, construction machinery and other industries are most widely used. (Specific parameters see this site or call for)

Two, self-locking gas spring (adjuster, gas pressure bar) in the medical equipment, seats and other products used in the most. This kind of gas spring with the help of some release mechanism can be stopped at any position in the stroke, and after stopping there is a great locking force (can reach more than 10000N). (Specific parameters see this site or call for)

Third, stop at will gas spring (friction gas spring) is mainly used in the kitchen furniture, medical equipment and other fields. Its characteristics between the free type gas spring and self-locking type gas spring: without any external structure and can stop at any position in the stroke, but no additional locking force. (Selection parameters can basically refer to the free-type gas spring)

Fourth, the damper in the automobile and medical equipment are used more, which is characterized by resistance to change with the speed of operation. It can obviously dampen the speed of the connected mechanism. (Specific parameters please call for)

Fifth, traction gas spring is a special gas spring: other gas spring in the free state are in the longest position, that is, after being subjected to external forces from the longest position to the shortest position of the movement, while the free state of the traction gas spring is in the shortest position, by the traction of the shortest position to the longest place to run. There are also free and self-locking types of traction gas springs. (Please call for specific parameters)
