[0023] See also Figure 1-3 ,This application provides a technical solution:

[0024] A tail throat installation structure includes an exhaust pipe cover 2 and a plug cover 1. The exhaust pipe cover 2 is made of plastic and has a plated surface. The plug cover 1 has a leather grain layer on its surface. The depth of the plug cover 1 is ≥50mm, and the depth of the inside of the exhaust pipe cover 2 is ≤20mm. Preferably, the depth of the plug cover 1 is 50mm, and the depth of the inside of the exhaust pipe cover 2 is 20mm. Figure 3 , Figure 3 In the embodiment, the depth of the plug cover 1 is about 58 mm, and the inner depth of the exhaust pipe cover 2 is about 10.2 mm. Those skilled in the art can make adjustments within the range disclosed in this application, and these adjustments are still within the scope of protection of this application.

[0025] By limiting the above dimensions, the depth is sufficient when the cover is used as a whole, and under the conventional electroplating process, the inner ring is corrosion-resistant without blistering, rusting, coating peeling and other appearance problems, so as to achieve the purpose of improving the real effect of the plastic exhaust pipe cover without causing product quality problems.

[0026] The plug cover 1 and the exhaust pipe cover 2 are fixed to each other by snapping. Figure 1 and Figure 2 As shown, the exhaust pipe cover 2 is provided with a clip, and the plug cover 1 is provided with a slot, which cooperates with the clip. The clip is provided with an inner ring clip 21 and an outer ring clip 22. The outer ring clip 22 is distributed along an elliptical path, located at the outermost end of the exhaust pipe cover 2 near the plug cover 1. The inner ring clip 21 is located inside the outer ring clip 22, arranged in a circular array. There are four inner ring clips 21 and four outer ring clips 22. This snap-fit ​​structure ensures stable installation. In actual implementation, limiting ribs can be used to control the assembly gap between the two.
