Description

Technical Field

[0001] The present application relates to the technical field of gas springs, and in particular to a high-strength gas spring. Background Art

[0002] Gas spring is an industrial accessory that can perform functions such as support, cushioning, braking, height adjustment and angle adjustment. It consists of the following parts: pressure cylinder, piston rod, piston, sealing guide sleeve, filler, cylinder control element and cylinder control element and joint, etc. The principle is to fill the closed pressure cylinder with inert gas or oil-gas mixture to make the pressure in the cavity several times or dozens of times higher than the atmospheric pressure. The cross-sectional area of ​​the piston rod is smaller than the cross-sectional area of ​​the piston to generate a pressure difference to achieve the movement of the piston rod. Gas springs have significant advantages over ordinary springs: relatively slow speed, little change in dynamic force, and easy control.

[0003] Gas springs are widely used in the fields of automobiles, aviation, furniture and machinery manufacturing. However, after the current gas springs are subjected to impact for a long time, the end caps at the ends of the gas springs will crack, making it difficult to use them at high intensity. This will cause the gas springs to leak, affecting their normal use. Therefore, in order to solve the above problems, we provide a high-strength gas spring. Utility Model Content
