[0002] The main structure of the spring-type hydraulic buffer is composed of a body, an axis, a bearing, an inner tube, a piston, a hydraulic shaft, a spring, etc. When the axis is impacted by an external force, it will drive the piston to squeeze the hydraulic oil in the inner tube. After the hydraulic oil is pressurized, it will be discharged one by one from the oil discharge holes of the inner tube. At the same time, the hydraulic oil discharged from the inner tube will also flow back to the inner tube through the oil return holes of the inner tube; when the external force disappears, the spring will rebound the piston to the starting point and wait for the next action. According to this principle, the hydraulic buffer will be able to effectively stop the moving object in a balanced manner, and is widely used in the field of elevators;
