  • the present invention relates to the field of spring manufacturing technology, and more particularly to a vertical and horizontal combined gas spring.
  • the 'spring' can be functionally divided into a compression spring, a torsion spring and a tension spring.
  • a commonly used compression spring is made of a strong elastic wire such as a steel wire which is spirally wound and elastically deformed to generate an elastic force. After the compression spring is formed, the elastic force is not adjustable, and it still occupies a large space after being compressed. When used in a spring mattress or the like, it cannot guarantee satisfactory comfort in each use area.

  • the upper and lower ends of the plurality of air column strips are respectively connected with a positioning member and have transverse and longitudinal ventilation passages therebetween, and the positioning member connects the plurality of air column belts and can form a support plane of the gas spring; the air permeability is good and difficult Deposition of moisture, avoiding the effects of the accumulated moisture on the human health when the spring is used in mattresses, sofas, massage chairs, cushions, etc.
  • the plurality of air column strips are partially connected, partially independent or separately, each of which is provided with a matching venting hole, and the plurality of air column strips are longitudinally disposed with lateral and longitudinal venting passages therebetween, according to the gas spring
  • the force distribution during use adjusts the gas pressure at different parts of the gas spring, which increases the gas pressure at which the gas spring is subjected to a large force.
  • the gas column belts are connected to each other and have at least one vent hole communicating with the accommodating chamber, and the gas pressure in each gas column belt is uniformly adjusted, which is convenient and quick, and avoids the phenomenon of unilateral tilt caused by uneven pressure of the gas spring.
