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

Embodiment 1

[0027] Such as Figure 1-Figure 3 As shown, the elastic force adjustable gas spring described in this embodiment includes a spring body, the spring body is formed by a hollow cavity column 1, and the cavity column 1 is a double-layer side wall structure. A closed chamber 2 containing pressure gas is formed between the double-layer side walls. The chamber column 1 is corrugated and has a vent hole 3 communicating with the chamber 2. The chamber column 1 has at least one layer of side walls Made of rubber, nylon, TPU or their composite materials with fabric, the rubber, nylon and / or TPU are filled in the pores of the fabric or attached to one side of the fabric. The upper and lower ends of the corrugated section in the middle of the cavity column 1 form two annular sections 5 with straight lines 4 that expand outward, and the outer ends of the two annular sections 5 have a cavity column mouth 8 with a reduced diameter. The linear surface 4 constitutes the connection surface, an...

Embodiment 2

[0031] Such as Figure 6-Figure 8 As shown, the cross-section of the chamber column 1 is circular, and the annular section 5 is also circular. There are two ventilation holes 3 and four ventilation holes 6 are evenly distributed on the annular section 5 in a cross shape.

[0032] In the technical solution of the present invention, the cross-section of the chamber column 1 can also be any polygon, and the thickness of the chamber 2 can be determined according to requirements.

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...
