Oil cylinder mechanism for hydraulic elevator

The invention relates to the technical field of oil cylinder structures, and discloses an oil cylinder mechanism for a hydraulic elevator, which comprises a body, the outer wall of the body is rotatably connected with a main body, the outer wall of the main body is fixedly provided with an oil tank, and the outer wall of the oil tank is provided with a double-color warning lamp. A first butt joint pipe and a second hydraulic pressurizing pipe penetrate through the outer wall of the oil tank, and the inner wall of the first butt joint pipe is fixedly sleeved with a first hydraulic pressurizing pipe. By means of the body, the main body, the oil tank, the first butt joint pipe and the micro heater device, in the using process of the oil cylinder, a user can directly pour sealed and stored damaged hydraulic oil into the oil tank, the hydraulic oil is purified through cooperation of the heating device and the stirring mechanism, and air in the hydraulic oil is separated from the hydraulic oil; therefore, a user do
