Description

Technical Field

[0001] The utility model relates to a damping device, in particular to the technical field of gas springs, and specifically to a highly versatile gas spring with side damping adjustment. Background Art

[0002] Compared with traditional mechanical springs, gas springs have the advantages of small size, large elastic force, long stroke, stable operation, high precision, long life, smooth elastic force curve, and no need for preload.

[0003] The gas spring in the prior art generally includes a cylinder, a threaded sleeve fixedly mounted on the upper end of the cylinder, and a plunger rod installed in the cylinder body and passed through the threaded sleeve. A sealing ring is provided on the outside of the threaded sleeve, which is in sealing contact with the inner wall of the cylinder. When working, the plunger rod is forced to move downward and form an elastic supporting force; when the force is removed, the plunger rod returns.

[0004] Conventional gas springs can only provide fixed damping. When different damping values ​​are required for different applications, springs with multiple damping values ​​need to be configured, and gas springs have low versatility.

[0005] Therefore, it is necessary to provide a highly versatile gas spring with one-side damping adjustment to achieve the above-mentioned purpose. Utility Model Content

[0009] Furthermore, the compression adjustment member is used as a damping adjustment actuator to adjust the amount of medium that can provide damping, thereby forming a gas spring structure with rapid damping adjustment.

[0010] Furthermore, the number of the damping medium flow channels B is several.

[0011] Furthermore, on the plug A, an end anti-collision elastic part is provided corresponding to the piston.
