Abstract
An elasticity-adjustable air pressure spring designed by the invention solves the technical problems of complex structure and top-to-bottom air impenetrability in the current gas springs. The elasticity-adjustable air pressure spring comprises a spring body, and is characterized in that the spring body is formed by at least one hollow cavity column of a double-layer sidewall structure, a closed cavity containing pressure air is formed between the double layers of the sidewall, the cavity column is corrugated, and at least one vent hole communicated with the cavity is arranged on the sidewall of the cavity column. By using the corrugated structure like an accordion box and filling the pressure air, the hardness of the elasticity-adjustable air pressure spring is adjusted, the elasticity-adjustable air pressure spring is particularly good in transverse and longitudinal ventilation, a mattress comprising the elasticity-adjustable air pressure spring is easy to remove moisture so that the influence on human body health is eliminated; the elasticity-adjustable air pressure spring is convenient in hardness adjustment and wide in one-way deformation range, meets various demands and can be…
