Abstract
The utility model relates to a piston mechanism, particularly to a piston mechanism for hydraulic cylinders. The piston mechanism comprises a cylinder block, wherein a piston rod is inserted in the cylinder block; a piston is arranged between the tail part of the cylinder block and the piston rod; the piston and the cylinder block are sealed and positioned through a guide ring and a Y-shaped ring; the sealing between the piston rod and the piston is realized by an O-shaped ring; the piston rod and the piston are locked through a round nut; and lock washers are arranged between the round nut and the piston. The piston mechanism for hydraulic cylinders is simple in structure and convenient to use.
