Description

Technical Field

[0001] The invention relates to the technical field of hydraulic oil cylinders, in particular to a hydraulic oil cylinder with a vibration reduction and buffering mechanism. Background Art

[0002] A hydraulic cylinder is a device that converts hydraulic energy into mechanical energy. Its input parameters are the flow rate and pressure of the oil, and its output parameters are the movement speed and force of the hydraulic cylinder. Specifically, the hydraulic cylinder generates linear motion through the pressure of the liquid to realize the conversion of hydraulic energy into mechanical energy of reciprocating linear motion. The working principle of the hydraulic cylinder is based on Pascal's law, that is, in a closed container, the magnitude of the pressure transmitted by the liquid is proportional to the transmitted force and has the same direction. A hydraulic cylinder is usually composed of a cylinder barrel, a piston, a piston rod, a seal, an inlet and outlet oil port and other components. Although some of the hydraulic cylinders on the market are equipped with shock absorption function, their shock absorption effect is still insufficient. During the use of the hydraulic cylinder, when the piston rod is retracted into the cylinder body, the original hydraulic oil at the bottom of the cylinder body will change due to the reduction in pressure. At this time, the piston seat at the bottom of the piston rod will strongly hit the bottom of the cylinder body under the action of pressure.
