DETAILED DESCRIPTION

[0020] The utility model will be further described in connection with the drawings and embodiments.

[0021] Please refer to Figure 1 , Figure 2 and Figure 3 , among which Figure 1 The utility model provides a main structure solid view of motorcycle shock absorber aluminium cylinder oil seal device Figure 1 ; Figure 2 The utility model provides a main structure solid view of motorcycle shock absorber aluminium cylinder oil seal device Figure 2 ;Figure 3 The structural view of the top column provided by this utility model.

[0022] In the specific implementation process, such as Figures 1-3 As shown, the device includes a sliding tube 1 and a fixed tube 2. A steel gasket 3 is placed at the sliding tube 1, and an oil seal body 4 is provided on one side of the steel gasket 3. Several positioning protrusions 5 are fixed circumferentially on the outer side of the oil seal body 4. When installing this oil seal device, the operator can first combine the sliding tube 1 and the fixed tube 2, put the oil seal body 4 on the sliding tube 1, and move the oil seal body 4 along the sliding tube 1 toward the position of the steel gasket 3 until the positioning protrusions 5 enter the through hole 8 to complete the fixation. The operation is simple and convenient, ensuring that the oil seal is installed in the correct position without deviation, and avoiding oil leakage.

[0023] The fixed tube 2 has an oil seal working area 6 and a dust seal working area 7 inside. The fixed tube 2 has several through holes 8 that run through it circumferentially. The through holes 8 are located in the oil seal working area 6. A rubber gasket 9 is fixed inside the through hole 8. The through hole 8 has an internal thread 10. A top post 11 is provided on one side of the fixed tube 2. The surface of the top post 11 has an external thread 12. One end of the top post 11 is located inside the through hole 8 and is in contact with the rubber gasket 9. By setting the rubber gasket 9, oil can be prevented from overflowing from the through hole 8. On the other hand, after the top post 11 is screwed into the through hole 8 through the thread, the top post 11 squeezes the rubber gasket 9 and the positioning protrusion 5 in contact with it, which can increase the pressure between the oil seal body 4 and the sliding tube 1, thereby further improving its sealing strength.

[0024] The end of the top post 11 that contacts the rubber pad 9 is rounded to prevent the top post 11 from damaging the rubber pad 9. The other end of the top post 11 is fixed with a rotating plate 13. The surface of the rotating plate 13 is provided with an internal hexagonal groove 14 to facilitate the use of tools by the staff to rotate the top post 11. The top post 11 is galvanized to improve its service life.

[0025] The working principle of this utility model is as follows: When installing this oil seal device, the operator can first combine the sliding tube 1 and the fixed tube 2, put the oil seal body 4 on the sliding tube 1, and move the oil seal body 4 towards the position of the rigid gasket 3 along the sliding tube 1 until the positioning protrusion 5 enters the through hole 8 to complete the fixing. The operation is simple and convenient, ensuring that the oil seal is installed in the correct position without deviation, and avoiding oil leakage.

[0026] By setting the rubber gasket 9, oil can be prevented from overflowing from the through hole 8. On the other hand, after the top post 11 is screwed into the through hole 8, the top post 11 squeezes the rubber gasket 9 and the positioning protrusion 5 in contact with it, which can increase the pressure between the oil seal body 4 and the sliding tube 1, thereby further improving its sealing strength.

[0027] The above merely illustrates the embodiments of the present application, and does not limit the patent scope of the present application, and any equivalent structure or equivalent process transformation, or direct or indirect application in other related technical fields, which are made by using the content of the present application specification and drawings, are also included in the patent protection scope of the present application.
