Elasticity-adjustable gas pressure spring

Abstract

The invention relates to an elasticity-adjustable gas pressure spring, which solves the technical problems of complicated structure and top-to-bottom stuffiness of a current gas spring. The elasticity-adjustable gas 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 side wall structure, a closed cavity containing pressure gas is formed between double side walls, the cavity columns are corrugated, and at least one vent hole communicated with the cavity is arranged on each side wall. By using the corrugated structure of a accordion box and filling the pressure gas, the hardness of the elasticity-adjustable gas pressure spring is conveniently adjusted, the elasticity-adjustable gas pressure spring is particularly fine in transverse and longitudinal ventilation, a mattress comprising the elasticity-adjustable gas pressure spring is easy for removing moisture so that the influence on human health is eliminated, the elasticity-adjustable gas pressure spring is wide in one-way deformation range, meets various demands and can be adjusted in real time to enhance comfort, coiling is facilitated, transport cost is saved, and a user can use the elasticity-adjustable gas pressure spring by filling the gas and unfolding the elasticity-adjustable gas pressure spring.

Description

technical field [0001] The invention relates to the technical field of spring manufacturing, in particular to an air pressure spring with adjustable elastic force. 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), an additional built-in spring, etc., and has a complex structure and high requirements for cooperation between parts, especially the pis...

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, a piston (push rod), an additional built-in spring, etc., and has a complex structure and high requirements for cooperation between parts. A cavity is formed in the middle to achieve the spring effect, but it has the disadvantage of not being ventilated up and down. When it is used as a mattress compression spring, the moisture generated by the human body or in the environment will accumulate and cannot be removed through air convection. The human body is in the air full of moisture. Sleeping on a spring mattress will inevitably affect your health; in addition, the above-mentioned gas spring has insufficient deformation stroke, the softness adjustment range is small, and the non-use state still occupies a large space
