[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes a damper fixed connection structure.

[0023] Please see Figures 1-4 A damper fixed connection structure includes a damper body 1 and a connector 2 disposed on the damper body. A through hole 3 is provided in the width direction of the damper body 1, and the connector 2 is disposed in the through hole 3. A straight knurled 4 is provided on the periphery of one end of the connector 2, and the straight knurled 4 is placed in the through hole 3.

[0024] The utility model discloses a kind of air door fixed connection structures, mainly including air door body 1 and connecting piece 2, by connecting piece 2 is set to long strip column structure, avoid connecting piece size deformation and position deviation, material cost is low, further guarantee air door rubber strip compression is more uniform, improve the sealing performance and service life of air door rubber strip, in addition, by setting straight line knurl 4 in one end of connecting piece 2, with interference fit of through hole 3, guarantee the stability of connecting piece 2 installation.
