Abstract

The invention relates to the technical field of springs, in particular to a gas spring. The gas spring comprises a cylinder body, a piston, a piston rod, a throttling groove, a protective cover and a guide sleeve, wherein the piston is arranged in the cylinder body, the piston is connected with the piston rod, the throttling groove is formed in the inner wall of one side of the cylinder body, the protective cover is arranged outside the piston rod, the guide sleeve is arranged in the cylinder body and a seal ring is arranged in the guide sleeve. The gas spring is simple, compact and reasonable in structure, convenient and rapid to assemble, reliable in connection, short in manufacturing period, high in work efficiency and good in sealing performance, quality of the product is improved, the service life of the gas spring is prolonged, the reliability of work of the gas spring is greatly improved, and the gas spring is easy to use and popularize.

Description

technical field [0001] The invention relates to the technical field of springs, in particular to a gas spring. Background technique [0002] The existing gas spring has a long manufacturing cycle, low work efficiency, and poor sealing performance, which reduces the quality of the product. It is difficult for the piston to be positioned accurately when the gas spring is working, which shortens the service life of the gas spring and greatly reduces the reliability of the gas spring. . Contents of the invention [0003] In order to overcome the disadvantages of poor sealing performance, inaccurate piston positioning, short service life and low working reliability of existing gas springs, the invention provides a gas spring. [0004] The technical solution adopted by the present invention to solve the technical problem is: a gas spring, comprising a cylinder body, a piston, a piston rod, a throttling groove, a shield and a guide sleeve, a piston is arranged in the cylinder bo...
