Disclosure of utility model
The utility model aims to solve the problem of poor sealing performance of the existing hydraulic oil cylinder in use, and provides a leakage-proof mechanism of the hydraulic oil cylinder.
In order to achieve the above purpose, the present utility model adopts the following technical scheme:
The utility model provides a hydraulic cylinder leak protection mechanism, includes the cylinder cap, the one end screw thread grafting of cylinder cap has the connector, and the one end of connector bonds there is interior sealing washer, the outer wall fixedly connected with clamp ring of connector, is equipped with outer sealing washer between clamp ring and the cylinder cap, the seal cover has been cup jointed in the outside of clamp ring, and the fixed cover has been cup jointed in the outside of seal cover.
Further, both ends of the fixed cover are fixedly connected with fixed blocks, one end of each fixed block is in threaded connection with a fixed bolt, and one end of each fixed bolt penetrates through the sealing sleeve and is in threaded connection with the cylinder cover.
Further, a transparent cover is adhered to the outer wall of one side of the cylinder cover, and the transparent cover covers the outer sides of the compression ring, the outer sealing ring, the fixed cover and the sealing sleeve.
Further, a plurality of locating rods are fixed on the inner wall of one side of the transparent cover, a plurality of locating holes are formed in one side of the cylinder cover, and the locating rods are spliced with the locating holes.
Further, the bottom fixedly connected with of cylinder cap connects the inner tube, and the bottom of connecting the inner tube is equipped with the sealing ring.
Further, a sealing gasket is arranged at the bottom of the cylinder cover.
The beneficial effects of the utility model are as follows:
1. The inner sealing ring is used for sealing the connector and the cylinder cover once, the outer sealing ring is used for sealing the connector and the cylinder cover twice, and the sealing sleeve is used for sealing the connector and the cylinder cover for three times, so that leakage of hydraulic oil is prevented.
2. The clamp ring, the outer sealing ring, the fixed cover and the sealing sleeve are protected through the transparent cover, so that damage to the outer sealing ring and the sealing sleeve is reduced, and usability of the outer sealing ring and the sealing sleeve is not affected.
3. Double sealing is carried out between the cylinder cover and the cylinder barrel through the sealing ring and the sealing gasket, so that leakage of hydraulic oil is avoided.
