Abstract
An oil pressure cylinder comprises a pressure cylinder body and a piston body, a piston channel is arranged at one end of the pressure cylinder body, and an oil change connector is arranged at the other end of the pressure cylinder body. An oil-discharging port and an exhaust port are formed in the position, close to the piston channel, of the pressure cylinder body wall. An oil return port is formed in the position, close to the oil change connector, of the pressure cylinder body wall. The piston body is movably arranged on the pressure cylinder body and provided with a pair of pistons and a piston rod, wherein the shape of the pistons corresponds to that of the inner periphery of the pressure cylinder body, and the piston rod is connected with the pistons. The pistons are arranged in the pressure cylinder body in a sliding mode and tightly attached to the cylinder wall. The piston rod penetrates through the piston channel and protrudes outside the pressure cylinder body. Due to the design of the oil change connector and the oil-discharging port, the purpose that oil is changed without disassembly of the oil pressure cylinder is achieved, and maintenance time is saved.
