[0021] In the above structure, through the spring 5 and the block 6 arranged on the inner wall of the square groove 3, and then through the elastic potential energy of the spring 5 itself, when the device needs to be installed, the block 6 can be squeezed toward the inner wall of the square groove 3, and the spring 5 can be compressed by the block 6, thereby causing the spring 5 itself to deform and shrink. At this time, the device can be quickly installed in the sealing ring of the shock absorber. Through the elastic potential energy of the spring 5, the block 6 is driven to pop outward, so as to be clamped with the edge of the sealing ring, so that the stability of the device is improved, so that it will not fall easily, the durability of the device is enhanced, and the oil sealing work can be better performed.

[0022] In a preferred embodiment, the shape of the square groove 2 4 matches the shape of the square groove 1 3 , and the square groove 2 4 penetrates the inner wall of the circular groove 2 .

[0023] In the above structure, through the penetration between the square groove 2 4 and the inner wall of the circular groove 2, when the sealing ring needs to be quickly disassembled, it is only necessary to squeeze the sealing ring inward through the square rod adapted to the square groove 2 4, so that the sealing ring body squeezes the block 6 to slide toward the inner side of the square groove 1 3, thereby causing the block 6 to squeeze the spring 5 again. At this time, the block 6 is received in the inner wall of the square groove 1 3, and the device can be quickly disassembled and removed smoothly.

[0024] In a preferred embodiment, the circular hole 7 passes through the inner wall of the oil seal body 1 and the inner wall of the circular groove 2 , and there are a plurality of circular holes 7 .

[0025] In the above structure, the circular hole 7 is provided to facilitate the injection of oil into the oil seal, thereby improving the lubricity of the device. At the same time, the shock absorbing performance of the shock absorber can be enhanced by injecting oil, thereby increasing the actual service life of the shock absorber.

[0026] In a preferred embodiment, the oil seal body 1 is made of nitrile rubber.

[0027] In the above structure, the oil seal body 1 made of nitrile rubber has good heat resistance and wear resistance, and is resistant to various lubricating oils, greases, and oil-gas mixtures, thereby further improving the oil seal performance of the shock absorber.

[0028] In a preferred embodiment, the number of the square groove 1 3 and the square groove 2 4 as well as the spring 5 and the clamping block 6 are all two groups, and are symmetrically distributed.

[0029] In the above structure, the stability of the device is improved by providing two sets of square grooves 1 3 and square grooves 2 4 as well as springs 5 ​​and clamping blocks 6.

[0030] In a preferred embodiment, a filter groove 9 penetrates the inner wall of the circular fixing plate 8 .

[0031] In the above structure, the circular fixing plate 8 is fixedly installed on the inner wall of the circular hole 7, so that on the one hand, when filling oil, the new oil is easy to flow into the shock absorber because the new oil has fewer impurities, thereby improving the shock absorption performance and service life of the shock absorber. On the other hand, since the old oil contains more impurities, the setting of the filter groove 9 increases the difficulty of the old oil leaking, so that the oil sealing performance of the device itself for the old oil is improved.

[0032] Working principle: when the device is needed, first, the spring 5 and the block 6 arranged on the inner wall of the square groove 3 can be used, and then the elastic potential energy of the spring 5 can be used. When the device needs to be installed, the block 6 can be squeezed toward the inner wall of the square groove 3, and the spring 5 can be compressed by the block 6, so that the spring 5 itself is deformed and contracted. At this time, the device can be quickly installed in the sealing ring of the shock absorber. The elastic potential energy of the spring 5 drives the block 6 to pop outward, so as to be clamped with the edge of the sealing ring, so that the stability of the device is improved, so that it will not fall easily, and the durability of the device is enhanced, so that the oil sealing work can be better performed. Secondly, the circular fixing plate 8 fixedly installed on the inner wall of the circular hole 7 is used, so that on the one hand, it is convenient to flow into the shock absorber when filling the oil because the new oil has fewer impurities, thereby improving the shock absorption performance and service life of the shock absorber. On the other hand, because the old oil contains more impurities, the setting of the filter tank 9 increases the difficulty of the old oil leaking, so that the oil sealing performance of the device itself for the old oil is improved.
