Gas spring with plurality of spiral columns

Abstract

The invention discloses a gas spring with a plurality of spiral columns, wherein a technical problem that conventional gas springs are complicated in structure and airproof up and down is solved. The gas spring comprises a spring body, and is characterized in that the spring body is formed by a bar-like air column which is provided with a pressure gas containing cavity; the air column repeatedly and alternately spirals from top to bottom or from bottom to top and forms the plurality of side-by-side and inclined spiral columns; the two adjacent spiral columns form a splay spiral unit; the adjacent spiral units are mutually connected; and at least one air hole for communicating the containing cavity is formed in the air column. According to the gas spring disclosed by the invention, the spiral columns are formed by one gas column, the interconnectedness is good, when the gas spring is subject to pressure, the spiral columns are mutually squeezed to buffer the pressure, the gas pressure is uniformly adjusted more conveniently, and the ventilation is good. Moisture of a mattress formed by the gas springs is easy to remove, hardness is convenient to adjust and the mattress is large in unidirectional deformation range; various requirements are met; the mattress also can be adjusted in real time; and the comfort level of the mattresses is increased.

Description

technical field [0001] The invention relates to the technical field of spring manufacturing, in particular to an air pressure spring with a plurality of helical columns. 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 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
