Combined cylinder cover with built-in split sealing gasket sleeve

The invention relates to the field of hydraulic oil cylinders, in particular to a combined cylinder cover with a built-in split sealing gasket sleeve, which comprises a cylinder cover body and the sealing gasket sleeve, and is characterized in that a sealing gasket sleeve groove is formed in one end of the cylinder cover body, and the sealing gasket sleeve is of a split structure and is formed bycombining two sealing gasket sleeves which are symmetrical left and right; the sealing gasket sleeve is installed in the sealing gasket sleeve groove and connected through screws or studs, and the screws or the studs are evenly distributed on the end face of the outer circle of the sealing gasket sleeve. The combined cylinder cover with the built-in split sealing gasket sleeves can effectively improve the efficiency of detecting whether the dustproof ring and the sealing ring are damaged or not, when the piston rod of the oil cylinder leaks oil, any one of the two symmetrical sealing gasket sleeves is taken down to qu
