Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic cylinders, in particular to a one-way hydraulic cylinder. Background Art

[0002] A one-way hydraulic cylinder is a device used to produce linear motion, usually consisting of a piston, a cylinder and hydraulic lines. Its working principle is to use the pressure of the hydraulic system to push the piston, thereby producing linear motion. In a one-way hydraulic cylinder, pressure acts on one side of the piston, while the other side is a low pressure or atmospheric pressure. When the hydraulic system applies pressure, the piston is pushed and moves in one direction, while no pressure is applied in the other direction, so the movement of the cylinder is one-way.

[0003] One-way hydraulic cylinders are usually used for some simple applications, such as door opening and closing, lifting systems, etc. Its structure is relatively simple and easy to operate. During use, the one-way hydraulic cylinder needs to cooperate with the hydraulic system through hydraulic pipelines, and mostly uses threaded connections. However, due to the long external oil pipe, there is dragging or external force during use, which makes the relative movement between the oil pipe and the interface loose, resulting in leakage of hydraulic oil in the pipe.
