In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] Please see Figures 1 to 4This utility model provides a technical solution: a waterproof connection structure for vehicle lights, including a lamp cover 1 and an outer shell 2. Multiple slots 3 are provided on the inner circumference of the outer shell 2, and multiple locking blocks 4 are provided on the outer circumference of the lamp cover 1. The outer sides of the locking blocks 4 engage with the inner sides of the slots 3. Multiple first limiting strips 5 are also provided on the outer circumference of the lamp cover 1, and each of the first limiting strips 5 has a first inclined surface 6 at one end. A rotating ring 7 is rotatably connected to the outer circumference of the outer shell 2. Multiple second limiting strips 8 are provided on the inner side of the rotating ring 7, and each of the second limiting strips 8 has a second inclined surface 9 at one end. A toothed groove 15 is provided on the outer circumference of the rotating ring 7. Multiple first movable grooves 10 are also provided on the outer circumference of the rotating ring 7, and a connecting block 11 slides on the inner side of each first movable groove 10. A second movable groove 12 is also provided on the outer circumference of the rotating ring 7, and a support is provided on the inner side of each second movable groove 12. The inner side of the support 13 is rotatably connected to a gear 14. The outer side of the gear 14 meshes with the inner side of the tooth groove 15. A handle 16 is fixed to the outer circumference of the gear 14. Slots 17 are provided on both the outer side of the gear 14 and the outer side of the support 13. A pin 18 is inserted into the inner side of the slot 17. A sealing ring 19 is provided between the lampshade 1 and the outer shell 2. Multiple locking blocks 4 are arranged at equal intervals. The positions of the multiple locking blocks 4 correspond to the positions of the multiple locking slots 3. Multiple first movable slots 10 are all arc-shaped structures and are arranged at equal intervals. The first limiting strip 5 and the second limiting strip 8 are both arc-shaped structures and are parallel to each other. The first inclined surface 6 and the second inclined surface 9 are parallel to each other. One end of the support 13 is fixedly connected to the outer side of the outer shell 2. One end of the connecting block 11 is fixedly connected to the outer circumference of the outer shell 2.

[0023] When the sealing ring 19 needs to be replaced, the pin 18 on the support 13 is pulled out, and the handle 16 is pulled to drive the gear 14 to rotate. The gear 14 meshes with the tooth groove 15 on the rotating ring 7, thereby driving the rotating ring 7 to rotate along the outside of the outer shell 2. The second limiting strip 8 on the rotating ring 7 disengages from the first limiting strip 5 on the lampshade 1, thereby separating the lampshade 1 and the outer shell 2. After replacing the sealing ring 19, the locking block 4 on the lampshade 1 is aligned with the locking groove 3 on the outer shell 2 and inserted. Then, the handle 16 is pulled to drive the gear 14 back to its original position. During this process, the rotating ring 7 rotates back, and the second limiting strip 8 gradually... As the lampshade 1 approaches the first limiting strip 5, the second inclined surface 9 on the second limiting strip 8 slips when it contacts the first limiting strip 5, thus pushing the lampshade 1 closer to the outer shell 2 and pressing the sealing ring 19. Finally, the pin 18 is passed through the slot 17 on the gear 14 and the support 13 to complete the fixing. Through the above process, the lampshade 1 and the outer shell 2 can be quickly disassembled and installed, saving manpower, improving efficiency, and solving the problem that when the waterproof adhesive ages, it is necessary to replace the waterproof adhesive at the joint and reduce the viscosity by heating the waterproof adhesive in order to separate the lampshade and the outer shell, which is a cumbersome process.

[0024] The specific usage and function of this embodiment: When the sealing ring 19 needs to be replaced, the pin 18 on the support 13 is pulled out, and the handle 16 is pulled to drive the gear 14 to rotate. The gear 14 meshes with the tooth groove 15 on the rotating ring 7, thereby driving the rotating ring 7 to rotate along the outside of the outer shell 2. The second limiting strip 8 on the rotating ring 7 disengages from the first limiting strip 5 on the lampshade 1, thereby separating the lampshade 1 and the outer shell 2. After replacing the sealing ring 19, the locking block 4 on the lampshade 1 is aligned with the locking groove 3 on the outer shell 2 and inserted. Then, the handle 16 is pulled to drive the gear 14 back to its original position. During this process, the rotating ring 7 rotates back, and the second limiting strip 8 gradually approaches the first limiting strip 5. The second inclined surface 9 on the second limiting strip 8 slips when it contacts the first limiting strip 5 on the first limiting strip 5, thereby pushing the lampshade 1 closer to the outer shell 2 and pressing the sealing ring 19. Finally, the pin 18 is passed through the slot 17 on the gear 14 and the support 13 to complete the fixing.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
