Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic oil cylinders, in particular to a hydraulic oil cylinder anti-leakage device. Background Art

[0002] The hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or swinging motion). It has a simple structure and reliable operation. When it is used to achieve reciprocating motion, the deceleration device can be eliminated, and there is no transmission gap and the movement is smooth. Therefore, it is widely used in the hydraulic systems of various machines. The hydraulic cylinder is basically composed of a cylinder barrel and a cylinder head, a piston and a piston rod, a sealing device, a buffer device and an exhaust device.

[0003] In the process of frequent rapid opening and closing of the piston rod of the existing hydraulic cylinder, the continuous friction on the inner wall of the cylinder causes the gap between the piston rod and the inside of the cylinder to increase, and finally oil leakage occurs, resulting in reduced work efficiency of the hydraulic cylinder, or even failure to work;

[0004] The existing patent (publication number: CN214036329U) is a hydraulic cylinder anti-leakage device. This utility model has a simple structure and good sealing performance. By setting an elastic sealing component, the sealing ring is squeezed by utilizing the bending ability of the U-shaped retaining spring. Under the compression of the first spring, the anti-extrusion property of the sealing ring is improved, and the sealing effect of the sealing ring is enhanced. It can prevent the leakage of hydraulic oil that occurs during the rapid reciprocating operation of the piston rod, and extend the service life. The dustproof sealing ring is set to avoid the invasion of dust and foreign matter to cause equipment.

[0005] In view of the above problems, the existing patents provide solutions, but in actual use, the installation effect of the oil pipeline is poor, and oil leakage is prone to occur. At the same time, the fixing effect of the top cover is not good, and the top cover is prone to fall off.

[0006] Therefore, a hydraulic cylinder anti-leakage device is proposed. Utility Model Content
