Title:
ELASTICITY-ADJUSTABLE GAS PRESSURE SPRING
Document Type and Number:
WIPO Patent Application WO/2013/107126
Kind Code:
A1
Abstract:
An elasticity-adjustable gas pressure spring comprising a spring body, and is characterized in that the spring body is formed by at least one hollow cavity column (1) of a double-layer side wall structure. A closed cavity (2) containing pressure gas is formed between the double-layer side walls. The cavity columns are corrugated, and at least one vent hole (3) communicated with the cavity (2) is arranged on the side walls. The hardness of the corrugated structure is adjusted by filling the pressure gas and can be adjusted conveniently. Moreover, the corrugated structure is wide in one-way deformation range and is fine in transverse and longitudinal ventilation. The elasticity-adjustable gas pressure spring solves the technical problems of complicated structure and top-to-bottom stuffiness of a current gas spring.
