Abstract
The utility model relates to a cylinder cover sealing mechanism, in particular to a cylinder cover sealing mechanism for a hydraulic oil cylinder. The cylinder cover sealing mechanism for the hydraulic oil cylinder comprises a piston rod and a cylinder cover. The piston rod penetrates through the cylinder cover, is closed with a head of the cylinder cover through a dustproof ring, is positioned with the cylinder cover through a guide ring and is closed with the cylinder cover through an O-shaped ring and a Y-shape ring. The cylinder cover sealing mechanism for the hydraulic oil cylinder is simple in structure and convenient to use.
