Vertically and horizontally combined gas pressure spring

Abstract

The invention relates to a vertically and horizontally combined gas pressure spring, which solves the problems of complicated structure and low compressive strength of a current gas spring. The vertically and horizontally combined gas pressure spring comprises a spring body and is characterized in that the spring body comprises a plurality of vertically arranged gas column strips with pressure gas containing cavities, horizontal hollow annular gas bags are sleeved on the gas column strips, the upper end and the lower end of each gas column strip are respectively positioned and connected, and gas pressure in the containing cavities can be adjusted. The hardness of the vertically and horizontally combined gas pressure spring is conveniently adjusted by filling pressure gas, particularly, the gas pressure spring has the advantage of large deformation travel, one-way deformation range is wide, the demands of various occasions are met, and the gas pressure spring can be adjusted in real time so that comfort is enhanced. Moreover, the gas pressure spring is convenient to coil, transport cost is saved, and a user can use the gas pressure spring only by filling the gas and the unfolding the gas pressure spring. Besides, the gas pressure spring is positioned in a vertically and horizontally combined manner, so that the gas pressure spring is stressed in a balanced manner, and damage caused by unbalanced stress of unilateral bias pressure is prevented.

Description

technical field [0001] The invention relates to the technical field of spring manufacturing, in particular to a vertically and horizontally combined gas 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 compressiv...

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
