Abstract
The utility model relates to a sealing mechanism of a piston rod, particularly a sealing mechanism of a piston rod for a three-stage oil cylinder, which comprises a cylinder and a piston rod, wherein the piston rod is arranged in the cylinder. The cylinder and the piston rod are sealed through a dustproof ring, an O-shaped ring and a sealing ring; a guide ring is arranged between the cylinder and the piston rod; and the cylinder and the piston rod are in stop connection through a stop ring. The sealing mechanism of the piston rod for the three-stage oil cylinder has the advantages of simplicity in structure and convenience in use.
