Abstract
A spiral air pressure spring designed by the invention solves the technical problems of complex structure and low compressive strength in the current gas springs. The spiral air pressure spring comprises a spring body, and is characterized in that the spring body is formed by an air column having a pressure air containing cavity, the air column is spiral, and at least one vent hole communicated with the containing cavity is arranged on the air column. The hardness of the spiral air pressure spring is adjusted by filling pressure air, the spiral air pressure spring is particularly large in deformation stroke and good in transverse and longitudinal ventilation, is used for manufacturing mattress, sofa, massage chair, cushion and the like, and is easy to remove moisture so that the influence on human body health is eliminated; the spiral air pressure spring is convenient in hardness adjustment and wide in one-way deformation range, meets the demands on various occasions and can be adjusted in real time to enhance the comfortable level; in addition, the spiral air pressure spring is convenient for coiled package to save the transportation cost, and can be unfolded by inflation when used by a user.
