Gas column band type gas spring

Abstract

The invention designs a gas column band type gas spring which solves the technical problems that a current gas spring has a complicated structure and is low in stressing strength. The gas column band type gas spring comprises a spring body and is characterized in that the spring body is composed of a plurality of gas column bands with pressure gas containing cavities, the upper end and the lower end of each gas column band are respectively connected with a positioning piece, and the gas pressure in the containing cavities is adjustable. According to the gas column band type gas spring, the softness and the harness of the gas spring are adjusted by filling the pressure gas, and particularly, the gas column band type gas spring has the advantages of large deformation range, good horizontal and longitudinal ventilation, the gas column band type gas spring is used for manufacturing a soft mattress, a set of sofa, a massage chair, a seat cushion and the like, can discharge moisture easily so as to eliminate the influence on the body health, is convenient in hardness adjustment and large in one-way deformation range, meets the demands of various occasions, can be adjusted in real time so as to improve the comfort, is convenient to roll so as to save the transportation cost and can be unfolded by gas filling when a user uses the gas column band type gas spring.

Description

technical field [0001] The invention relates to the technical field of spring manufacturing, in particular to an air column band type air 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 placed in a single-layer cavity, a piston (push rod), an additional inner spring, etc. The spring body is composed of a single cavity column, with low compressive strength and ...

AI Technical Summary

Problems solved by technology

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 will have a satisfactory degree of comfort.

Although someone has designed a gas spring, it is composed of a cylinder placed in a single-layer cavity, a piston (push rod), an additional inner spring, etc. The spring body is composed of a single cavity column, with low compressive strength and complex structure. In addition, the deformation stroke of the gas spring mentioned above is insufficient, the adjustment range of softness and hardness is small, and the non-use state still occupies a large space
