[0002] At present, in automobile parts, oil seals can effectively prevent liquid media from leaking from the sealed mechanism. Generally, the outer surface of the oil seal is a smooth cylindrical surface, and the sealing is guaranteed by the interference fit of the rubber ring, which can achieve a good sealing effect. The oil seal seat in the shock absorber is integrally processed, and the sealing gasket is installed between the oil seal seat and the oil storage cylinder. The oil seal seat needs to be rotated when assembled with the oil storage cylinder. At this time, the sealing ring will also rotate with the oil seal seat. Therefore, an automobile oil seal sealing structure is particularly needed.

[0003] However, in the existing automobile oil seal structure, since the sealing gasket in the shock absorber is an integrated design, the friction between the sealing gasket and the oil reservoir will decrease during rotation, and then the sealing gasket will be squeezed out when the internal pressure of the oil reservoir is too high. In addition, the gasket needs to be replaced immediately after a certain amount of wear occurs, which affects the oil seal effect. Utility Model Content

[0004] The purpose of the utility model is to provide an automobile oil seal structure to solve the problem that the existing automobile oil seal structure proposed in the above background technology, because the sealing gasket in the shock absorber is an integrated design, the friction between the sealing gasket and the oil storage cylinder will become smaller during the rotation process, and then when the internal pressure of the oil storage cylinder is too large, the sealing gasket will be squeezed out, and the gasket needs to be replaced immediately after a certain amount of wear occurs, which affects the oil seal effect.

[0010] Preferably, one end of the dustproof gasket is embedded in the inner groove, and the fastening rubber ring is arranged in the first limiting groove.

[0011] Compared with the prior art, the beneficial effect of the utility model is that: in the automobile oil seal structure, when the second gasket rotates with the oil seal seat, the first gasket rotates together, but the first gasket and the oil storage cylinder do not rotate relative to each other, and the second gasket and the oil seal seat do not rotate relative to each other, thereby reducing wear and tear, thereby preventing the first gasket and the second gasket from falling off, and when a certain amount of wear occurs, the tightening rubber ring and the annular spring respectively tighten one side of the first gasket and the second gasket, so that they fit tightly with the oil storage cylinder and the first gasket again, thereby extending the service life and reducing replacement.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-4 The utility model provides a technical solution: an automobile oil seal structure, comprising a first gasket 1, a second gasket 2 is sleeved on the surface of the first gasket 1, an oil storage cylinder 3 is connected to the inner side of the first gasket 1, a dustproof fastening mechanism 4 is arranged on one side of the surface of the first gasket 1, and an anti-slip mechanism 5 is arranged on one side of the surface of the second gasket 2;

[0019] The anti-slip mechanism 5 includes a rubber block 501, a second limiting groove 502, a clamping groove 503, an annular groove 504, an annular spring 505 and an annular block 506. The rubber block 501 is connected to one side of the surface of the first gasket 1, the second limiting groove 502 is opened on one side of the surface of the second gasket 2, the clamping groove 503 is opened on one side of the surface of the second gasket 2, the annular groove 504 is opened on one side of the surface of the second gasket 2, an annular spring 505 is sleeved on one side of the surface of the second gasket 2, and the surface of the rubber block 501 is connected to the annular block 506. When the first gasket 1 and the second gasket 2 are prevented from slipping and friction, firstly, the first gasket 1 and the second gasket 2 are both hollow ring bodies, and their main materials are both rubber. Then, the first gasket 1 is sleeved on the outer surface of the oil delivery barrel, and then the annular spring 505 is sleeved on one side of the surface of the second gasket 2. 5 is sleeved into the second limiting groove 502 on one side of the second gasket 2, and the annular spring 505 plays the role of tightening and maintaining a certain elasticity. Then, the rubber block 501 on one side of the second gasket 2 is clamped into the clamping groove 503 to achieve a preliminary limiting seal. At the same time, the ring block 506 on the surface of the rubber block 501 is embedded in the annular groove 504 to further enhance the stability of the connection. In this way, the connection between the first gasket 1 and the second gasket 2 is completed. Thereafter, the surface of the second gasket 2 is installed on the oil seal seat. When the second gasket 2 rotates with the oil seal seat, the first gasket 1 is driven to rotate together through this connection mechanism, but the first gasket 1 and the oil storage cylinder 3 do not rotate relative to each other, and the second gasket 2 and the oil seal seat do not rotate relative to each other, thereby reducing wear and preventing the first gasket 1 and the second gasket 2 from falling off.

[0020] Furthermore, the annular spring 505 is sleeved inside the annular groove 504, and two groups of annular springs 505 are provided. Through the setting of the annular springs 505, when in use, the annular springs 505 provide elastic fastening force. After the second washer 2 is worn to a certain extent, the annular springs 505 can also tighten one side of the second washer 2 so that it can fit tightly with one side of the first washer 1.

[0021] Furthermore, the size of the ring block 506 matches that of the ring groove 504, and one end of the rubber block 501 matches that of the clamping groove 503. By setting the rubber block 501 and the ring block 506, when in use, the rubber block 501 is a key component connecting the first gasket 1 and the second gasket 2. After the rubber block 501 is clamped with the clamping groove 503, the first gasket 1 and the second gasket 2 can be connected together. The ring block 506 and the ring groove 504 are precisely matched to strengthen the tightness of the connection between the first gasket 1 and the second gasket 2.

[0022] Furthermore, the dustproof fastening mechanism 4 includes an inner groove 401, a first limiting groove 402, a fastening rubber ring 403 and a dustproof gasket 404. The inner side of the first gasket 1 is provided with an inner groove 401, the surface of the first gasket 1 is provided with a first limiting groove 402, the surface of the first gasket 1 is sleeved with a fastening rubber ring 403, and the inner side of the first gasket 1 is embedded with a dustproof gasket 404. Through the arrangement of the inner groove 401, the first limiting groove 402, the fastening rubber ring 403 and the dustproof gasket 404, when in use, when the first gasket 1 is continuously sleeved onto the surface of the oil storage cylinder 3, the dustproof gasket 404 located on the inner side of the first gasket 1 will be continuously squeezed from the oil storage cylinder 3 during this process. As this squeezing continues, one side of the dustproof gasket 404 will gradually be squeezed into the inner groove 401, and the elastic properties of the dustproof gasket 404 itself , which will cause it to generate a reverse force, and this reverse force will enable the dustproof gasket 404 to be tightly attached to the surface of the oil storage cylinder 3, thereby forming an effective barrier to prevent external dust from entering. At the same time, the size of the fastening rubber ring 403 is relatively smaller than the inner ring diameter of the first gasket 1. When the fastening rubber ring 403 is sleeved into the first limiting groove 402, due to its size characteristics, the fastening rubber ring 403 will be continuously tightened. This tightening effect will further drive the first gasket 1 to fit more closely to the surface of the oil storage cylinder 3. Even if the inner side of the first gasket 1 has a certain degree of wear after a period of use, due to the tightening effect of the above-mentioned fastening rubber ring 403 and the elasticity and reverse force of the dustproof gasket 404, it is still possible to ensure that the first gasket 1 and the oil storage cylinder 3 remain in a tightly fitted state.

[0023] Furthermore, one end of the dustproof gasket 404 is embedded in the inner groove 401, and the fastening rubber ring 403 is sleeved in the first limiting groove 402. Through the arrangement of the fastening rubber ring 403 and the dustproof gasket 404, when in use, the fastening rubber ring 403 utilizes its characteristic of being smaller than the inner ring diameter of the first gasket 1 to generate a tightening force after being sleeved into the first limiting groove 402, thereby driving the first gasket 1 to fit the oil storage cylinder 3 more closely, thereby enhancing the stability of the connection. At the same time, when the inner side of the first gasket 1 is worn, it can still maintain a tight fit state, thereby ensuring its sealing and fixing functions. The dustproof gasket 404 fits tightly to the oil storage cylinder 3 through its own elastic deformation, thereby effectively preventing external dust from entering between the dustproof gasket 404 and the oil storage cylinder 3.

[0024] Working principle: First, when the first gasket 1 and the second gasket 2 are prevented from falling off and friction, the first gasket 1 and the second gasket 2 are both hollow rings, and their main materials are rubber. Then, the first gasket 1 is sleeved on the outer surface of the oil barrel, and then the annular spring 505 is sleeved into the second limiting groove 502 on one side of the second gasket 2. The annular spring 505 plays a role in tightening and maintaining a certain elasticity. Then, the rubber block 501 on one side of the second gasket 2 is inserted into the slot 503 to achieve a preliminary limiting seal. At the same time, the ring block 505 on the surface of the rubber block 501 06 is embedded in the annular groove 504 to further enhance the stability of the connection, thus completing the connection between the first gasket 1 and the second gasket 2. Then, the surface of the second gasket 2 is mounted on the oil seal seat. When the second gasket 2 rotates with the oil seal seat, the first gasket 1 is driven to rotate together through this connection mechanism, but the first gasket 1 and the oil storage cylinder 3 do not rotate relative to each other, and the second gasket 2 and the oil seal seat do not rotate relative to each other, thereby reducing wear and preventing the first gasket 1 and the second gasket 2 from falling off. Then, when the first gasket 1 is continuously sleeved onto the surface of the oil storage cylinder 3, The dustproof gasket 404 located inside the first gasket 1 will be continuously squeezed by the oil storage cylinder 3 during this process. As this squeezing continues, one side of the dustproof gasket 404 will gradually be squeezed into the inner groove 401. The elastic properties of the dustproof gasket 404 itself will cause it to generate a reverse force. This reverse force will enable the dustproof gasket 404 to be tightly attached to the surface of the oil storage cylinder 3, thereby forming an effective barrier to prevent external dust from entering. At the same time, the size of the fastening rubber ring 403 is relatively smaller than that of the first gasket 1. The inner ring diameter of the gasket 1, when the fastening rubber ring 403 is sleeved into the first limiting groove 402, due to its size characteristics, the fastening rubber ring 403 will be continuously tightened, and the tightening effect will further drive the first gasket 1 to fit more closely to the surface of the oil storage cylinder 3. Even after a period of use, the inner side of the first gasket 1 has a certain degree of wear and tear. Due to the tightening effect of the fastening rubber ring 403 and the elasticity and reverse force of the dustproof gasket 404, it is still possible to ensure that the first gasket 1 and the oil storage cylinder 3 remain in a tightly fitted state.

[0025] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
