Oil pipe pad of hydraulic cylinder

The utility model relates to an oil pipe pad of a hydraulic cylinder, which provides a simple pressure supply structure of a hydraulic cylinder. Space with proper distance is arranged at the tail end of an inner pipe of a hydraulic cylinder and the fixed end of the hydraulic cylinder. An oil pipe pad is arranged at the tail end of the inner pipe. The end surface of the tail end of the inner pipe is just sealed by the periphery of the oil pipe pad, so that the inner pipe of the hydraulic cylinder is isolated from an outer pipe. The oil pipe pad is provided with a penetrating hole. The size of the hole diameter of the penetrating hole is determined by pressure required by the hydraulic cylinder, so as to control the pressure of an acting rod of the hydraulic cylinder when the acting rod acts.
