[0002] A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or oscillating motion). It has a simple structure and reliable operation. When used to achieve reciprocating motion, it eliminates the need for a speed reduction device and has no transmission backlash, resulting in smooth movement. Therefore, it is widely used in the hydraulic systems of various machines. The output force of a hydraulic cylinder is directly proportional to the effective area of ​​the piston and the pressure difference between its two sides. A hydraulic cylinder basically consists of a cylinder barrel and cylinder head, a piston and piston rod, a sealing device, a buffer device, and an exhaust device. The buffer device and exhaust device are determined according to the specific application. The other devices are essential. Currently, some dustproof devices used for hydraulic cylinders on the market have relatively simple structures and are basically directly installed on the hydraulic cylinder, making it impossible to adapt them for different sizes of hydraulic cylinders.
