Gas bag stacking type gas pressure spring

Abstract

The invention relates to a gas bag stacking type gas pressure spring, which solves the technical problems of complicated structure and top-to-bottom stuffiness of a current gas spring. The gas bag stacking type gas pressure spring comprises a spring body and is characterized in that the spring body comprises a plurality of stacked hollow annular gas bags, the adjacent gas bags are connected by an upper surface and a lower surface, and at least one vent hole is arranged on each gas bag. The gas bag stacking type gas pressure spring overcomes the defects of easiness in corrosion, non-adjustability of elastic force and the like of a metal spring, the hardness of the gas pressure spring is conveniently adjusted by filling pressure gas, and particularly the gas pressure spring has the advantages of large deformation travel and fine horizontal and vertical ventilation, and is used for manufacturing a soft mattress, a sofa, a massage chair, a seat cushion and the like, easily eliminating moisture and removing the influence on human health. 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. Besides, the gas pressure spring is convenient to coil, transport cost is saved, and a user can use the gas pressure spring by filling the gas and unfolding the gas pressure spring.

Description

technical field [0001] The invention relates to the technical field of spring manufacturing, in particular to an air bag stacked 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, a piston (push rod), an additional built-in spring, etc., and has a complex structure and high requirements for cooperation between parts, especially the pistons are arranged at th...

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
