In order to achieve the purpose, the utility model adopts an air cylinder which comprises a cylinder body and a piston assembly, wherein a front cover is arranged at one end of the cylinder body, a rear cover is arranged at the other end of the cylinder body, a cavity for placing the piston assembly is formed between the cylinder body and the front cover as well as between the cylinder body and the rear cover, a first air hole and a second air hole which are communicated with the cavity are respectively arranged at two ends of the cylinder body, the piston assembly comprises a piston which is movably arranged in the cavity and a piston rod which is arranged in a linkage manner with the piston, a piston sealing ring which is in sealing fit with the cylinder body is arranged on the piston, a wear-resisting ring which is in fit with the cylinder body is arranged on the piston, and an anti-collision pad is arranged on one side of the piston which faces the rear cover.
The beneficial effect of above-mentioned structure is: be provided with wear ring on the piston, can prolong the life of piston, and be provided with the crashproof pad on the piston, the crashproof pad can play the cushioning effect, can avoid the piston directly to strike on the hou gai, is favorable to improving the operational reliability of this cylinder, and the back lid riveting is on the cylinder body, and structural design is compacter, and it is more convenient to assemble to this cylinder has simple structure, stable performance is reliable, the assembly is convenient, long service life's advantage.
Particularly, clamping grooves are respectively formed in the positions, corresponding to the two sides of the first air hole and the second air hole, of the cylinder body. Be provided with the joint groove on the cylinder body to be convenient for connect the joint with first gas pocket, second gas pocket, thereby be favorable to improving the installation effectiveness of this cylinder.
In particular, an oil-containing bearing is arranged between the piston rod and the front cover. The oil-retaining bearing can reduce the friction coefficient, so that the friction force between the piston rod and the front cover can be reduced, and the service life of the air cylinder can be prolonged.
Particularly, a limiting groove is formed in the opening at one end of the cylinder body and corresponds to one side of the front cover, a limiting check ring is arranged in the limiting groove and abuts against one side of the front cover, and the limiting check ring is in limiting fit with the front cover. Be provided with spacing retaining ring on the cylinder body, spacing retaining ring can compress tightly the protecgulum in the cylinder body to can guarantee that the cylinder body is connected compacter with the protecgulum.
In particular, a dustproof ring is arranged between the piston rod and the front cover. The dustproof ring can play a dustproof role and can prevent dust from entering the cylinder body, so that the working reliability of the cylinder can be improved.
In particular, the front cover is provided with a buffer pad matched with the piston. The buffer pad can play the cushioning effect, can avoid the direct striking of piston on the protecgulum, avoids the piston to receive the damage to be favorable to prolonging the life of this cylinder.
