Definitions

  • the present invention relates to the field of spring manufacturing technology, and more particularly to a ring-type 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.
