Description

Technical Field

[0001] The utility model relates to the technical field of springs, in particular to a damping gas spring which can be stopped at will. Background Art

[0002] A gas spring is a device that uses the compression and expansion of gas to store and release energy. It is usually used to provide auxiliary support or cushioning. Its working principle is based on the gas law. The piston moves in a closed cylinder and the compressed gas generates elastic force.

[0003] A Chinese patent with publication number CN210889881U discloses a high-performance segmented damping gas spring. The damping gas spring cylinder body of the utility model is in the shape of a long cylinder. The rear end of the cylinder body is connected to a sealing seal. A guide sleeve is provided in the cylinder body. The guide sleeve is fixed to the front end of the cylinder body. The piston assembly is slidably sealed with the inner side wall of the cylinder body. The piston assembly is fixedly arranged at the rear end of the piston rod. The front end of the piston rod passes through the cylinder body and is slidably sealed with the guide sleeve. A plurality of bypass grooves are provided on the inner side wall of the cylinder body, and a plurality of concave and convex structures are provided to achieve a stopping effect.

[0004] The protective shell of the above-mentioned gas spring can be limited to stop, and it includes multiple concave and convex structures, which makes the internal structure complicated. The installer needs to spend more time and energy to understand and adapt to these structures, which increases the difficulty and time of installation. Although there are many stop positions, the stop adjustment at any position cannot be performed. This means that the user cannot adjust the stop position of the gas spring at will according to actual needs during use, which limits the flexibility and practicality of the device, and needs to be optimized and improved.
