Abstract
The utility model provides a hydraulic cylinder piston and a piston rod structure. The hydraulic cylinder piston and the piston rod structure comprise the piston, a piston rod and a fixing structure between the piston and the piston rod. The piston rod is a stepped shaft and is provided with a first step, a second step, a third step, a fourth step, a fifth step and a sixth step, wherein the first step is arranged at a shaft end, the shaft diameter of the first step and the shaft diameter of the third step are larger than the shaft diameter of the second step, the shaft diameter of the third step and the shaft diameter of the fifth step are larger than the shaft diameter of the fourth step, and the shaft diameter of the fifth step is smaller than that of the sixth step. The piston is a cylindrical body, a hole is arranged in the middle of the piston, one end of the piston is stuck at a shaft shoulder of the sixth step, and the other end of the piston is the fixing structure between the piston and the piston rod. The hydraulic cylinder piston and the piston rod structure are improvement for an existing hydraulic cylinder piston and an existing piston rod structure, the fixing device is compact and therefore operation of the piston and the piston rod is stable.
