A helical gas spring

Abstract

The invention designs a spiral air pressure spring which solves the technical problem that the existing air pressure spring has a complicated structure and low compressive strength. The spiral air pressure spring comprises a spring body which is characterized in that an air column provided with a pressure air containing cavity forms the spring body, the air column is spiral, and is provided with at least one air vent communicated with the containing cavity. The softness and hardness of the spiral air pressure spring is adjusted by filling of the pressure air, in particularly, the spring has the advantages of large deformation stroke and good transverse and longitudinal ventilation, and can be used for manufacturing a mattress, a sofa, a massage armchair, a seat cushion and the like; the humidity is easily eliminated, and the influence to the human health is removed; the softness and hardness adjustment is convenient and the single deformation range is large; the spring meets needs in various occasions, and can be timely adjusted to increase the comfortable level; the spring is convenient for package so as to save the transportation cost, and can be unfolded by inflating when being used by a user.

Description

technical field [0001] The invention relates to the technical field of spring manufacturing, in particular to a helical gas pressure spring. Background technique [0002] "Spring" can be divided into compression spring, torsion spring and tension spring in terms of function. The commonly used compression spring is made of steel wire and other elastic metal wires in a spiral shape, and its elastic deformation is used to generate elastic force. The elastic force of this type of compression spring is not adjustable after it is formed, and it still occupies a large space after being compressed. After being used in places such as spring mattresses, it cannot guarantee that each area of ​​use has a satisfactory degree of comfort. Although someone has designed a gas spring, it is composed of a cylinder, a piston (push rod), and an additional built-in spring. The non-used state still takes up a lot of space. Contents of the invention [0003] The object of the present invention ...
