| 摘要 |
The invention relates to mechanisms preventing the rotational motion of a gas spring (2), which is centered inside an external pipe (5), and which has the potential of upwards and downwards motion (11,12), thereby, in order to cancel the rotational motion of the gas spring (2), the mechanism comprises: a guide matrix (3), which is fixed on said gas spring (2) external surface (2.1) by close fit or by being adhered between said external pipe (5) and gas spring (2), and the outer diameter edges of which has polygonal geometry; a female guide matrix (4), which has the same geometric form as the guide matrix (3) having said polygonal geometry, and which are centered together with each other, and a connection component (6) providing fixation of the female guide matrix (4) on the external pipe (5).
