[0022] 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.

[0023] Example: Reference Figure 1-8 The sealing structure of a car air-conditioning damper shown in the figure includes a moving head 1, a rotating shaft 2, a damper body 3, and a seal 4. The moving heads 1 are provided at both ends of the rotating shaft 2. The damper body 3 connects the rotating shaft 2 and the moving head 1. A seal 4 is provided at the edge of the outer damper body 3.

[0024] In order to realize the rapid disassembly and assembly of the seal 4, a U-shaped installation strip 31 is provided at the edge of the damper body 3. The thickness of the installation strip 31 is less than that of the damper body 3, and a limiting groove 32 for positioning is provided at the end of the installation strip 31. The seal 4 in this embodiment is U-shaped, and the sealing groove 41 provided on its inner wall is matched with the installation strip 31. In order to fix the seal 4, a limiting block 42 matched with the limiting groove 32 is provided on the inner wall of the sealing groove 41. Compared with the existing glue fixing method, the first step of installation of the seal in this embodiment has a higher fault tolerance rate and will not have the misalignment problem of the glue fixing method.

[0025] In order to further fix the installation state of the seal 4, a positioning head 11 is provided on the outer wall of the moving head 1 (between the two groups of damper bodies 3), and a threaded hole is provided on the end face of the positioning head 11; the mounting block 5 is an arc-shaped member, and a positioning hole 51 is provided in the middle of its arc surface, and the cross-section of the positioning hole 51 is a "convex" shape. The end face of the mounting block 5 fits between the damper body 3 and the seal 4, and the positioning hole 51 is adapted to the positioning head 11. After the positioning head 11 and the mounting block 5 are connected, a bolt is used to pass through the positioning hole 51 and screwed into the threaded hole of the positioning head 11 to complete the installation of the mounting block 5, and the seal 4 is pressed to prevent it from falling off.

[0026] A T-shaped auxiliary groove 52 is provided on the end face of the mounting block 5, and an auxiliary strip 6 is slidably connected in the auxiliary groove 52. The auxiliary strip 6 and the seal 4 correspond in position and size. The convex strip provided on the end face of the auxiliary strip 6 further presses the seal 4 to limit the seal 4.

[0027] The working principle of the utility model is as follows: the sealing groove 41 of the sealing strip 4 is aligned with the mounting strip 31 on the damper body 3, and then the sealing strip 4 is pushed to make the sealing groove 41 contact with the mounting strip 31. After the sealing strip 4 is pushed to the end of the mounting strip 31, the limiting block 42 in the sealing groove 41 cooperates with the limiting groove 32 to achieve the first step of fixation, and then the auxiliary strip 6 is inserted into the auxiliary groove 52 at the end of the mounting block 5, and then the positioning hole 51 of the mounting block 5 is aligned with the positioning head 11 on the moving head 1. After the docking is completed, the bolt is used to penetrate the positioning hole 51 and is threadedly connected with the threaded hole of the positioning head 11 to achieve fixation, and the convex strip of the auxiliary strip 6 is pressed against the sealing strip 4, and then the moving head 1 is connected to the driving end to complete the installation of the damper.
