[0038] Working principle: When in use, when the hydraulic cylinder is in use, it is installed at the use position through the connecting ring A110 and the connecting ring B130. When the hydraulic cylinder operates, the piston rod 120 moves telescopically on the cylinder body 100.

The lubricating oil flows downward to the stop valve 540 part. The on-off of the injection pipe A541 is controlled by the stop valve 540. The lubricating oil can enter the inside of the connecting ring A110 through the injection pipe A541 and lubricate the connecting part between the connecting ring A110 and the connecting part, enabling automatic lubrication operation for the connecting part of the hydraulic cylinder and the piston rod 120. The joint 350 is installed on the installation oil nozzle 310 through the installation nut 340, and the external hydraulic oil pipe is connected to the joint 350.
