In order to achieve the above purpose, the cylinder capable of preventing the piston rod from rotating comprises a cylinder barrel, a front end cover arranged at one end of the cylinder barrel, a rear cover arranged at the other end of the cylinder barrel, a piston and a piston rod in linkage fit with the piston, wherein a piston cavity is formed between the cylinder barrel and the front end cover and between the cylinder barrel and the rear cover, the piston is arranged in the piston cavity in a sliding mode, a through hole through which the piston rod can pass is formed in the front end cover, one end of the piston rod passes through the through hole and extends out of the front end cover, a guide plane matched with the piston rod is arranged in the through hole, a sliding plane matched with the guide plane is arranged on the peripheral wall of the piston rod, and the sliding plane moves along with the piston rod and can slide back and forth on the guide plane.
The structure has the beneficial effects that the guide plane which plays a guide role on the piston rod is arranged in the through hole of the front end cover, the sliding plane of the piston rod can slide back and forth along the guide plane, the angle can not be changed in the telescopic movement process of the piston rod, the piston rod can not rotate at will, and therefore the cylinder can position the direction of the driving piece. Therefore, the cylinder has the advantages of simple structure, stable and reliable performance and capability of preventing the piston rod from rotating.
In particular, a buffer cushion matched with the piston is arranged in the front end cover. The buffer cushion can play a role in buffering, can reduce the impact of the front end cover on the piston, and is beneficial to prolonging the service life of the cylinder.
In particular, the piston is provided with a wear-resistant ring matched with the cylinder barrel. The wear-resistant ring can enhance the wear resistance of the piston and prolong the service life of the piston.
In particular, a shock pad matched with the rear cover is arranged at one end of the piston. The shock pad can play the cushioning effect, can reduce the impact of back lid to the piston to be favorable to improving the life of this cylinder.
Particularly, sealing rings are respectively arranged between the cylinder barrel and the front end cover, between the front end cover and the piston rod and between the piston and the cylinder barrel. The sealing ring can play a sealing role, so that the sealing performance of the cylinder is improved.
