[0023] 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.

[0024] The utility model provides Figure 1-4 The corrosion-resistant automobile exhaust tail pipe shown comprises an exhaust tail pipe 1, one end of which is provided with a delivery assembly 2 for connecting a muffler, and further comprises:

[0025] The delivery assembly 2 includes a delivery pipe 21 and a first reducer 22. The delivery pipe 21 is used to connect to the muffler, and the first reducer 22 is used to connect to the exhaust tail pipe 1.

[0026] The connecting assembly 3 is used to improve the sealing performance of the connection between the discharge tail pipe 1 and the conveying assembly 2. The connecting assembly 3 includes a second reducer 31 and a close-fitting pipe 32. The second reducer 31 is used to connect the discharge tail pipe 1. The close-fitting pipe 32 is sleeved on the outer wall of the first reducer 22.

[0027] A sealing member, the sealing member is arranged close to the inner wall of the tube 32;

[0028] The throat hoop 4 is sleeved on the outer wall of the pipe 32 .

[0029] Specifically, one end of the discharge tail pipe 1 is connected with one side of the second reducer 31, one side of the close-fitting tube 32 is connected with the other side of the second reducer 31, the first reducer 22 is sleeved inside the close-fitting tube 32, and the other side of the close-fitting tube 32 is connected with a sleeve tube 33 for sleeved on the outer wall of the delivery pipe 21. The close-fitting tube 32 and the first reducer 22 are used to prevent the increase of the external size of the connecting component 3. The sealing member includes a sealing ring 5, the outer wall of the sealing ring 5 is fixedly connected to the inner wall of the close-fitting tube 32, the sealing ring 5 is sleeved on the outer wall of the first reducer 22, and the vertical cross-section of the sealing ring 5 is O-shaped.

[0030] Furthermore, the exhaust tail pipe 1, the second reducer 31, the close-fitting tube 32 and the sleeve tube 33 are all made of stainless steel. The stainless steel material has the characteristics of strong corrosion resistance, high mechanical strength, and high temperature resistance, so that the exhaust tail pipe 1 and the connecting component 3 can be more durable. The exhaust tail pipe 1 is fixed by welding at one end opposite to the second reducer 31, the second reducer 31 is fixed by welding at one end opposite to the close-fitting tube 32, the close-fitting tube 32 is fixed by welding at one end opposite to the sleeve tube 33, the second reducer 31 and the sleeve tube 33 have the same size, the sleeve tube 33 is sleeved on the outer wall of the delivery pipe 21, and the close-fitting tube 32 is sleeved on the outer wall of the first reducer 22. The sealing ring 5 is made of high-temperature resistant rubber material, such as nitrile rubber, and the sealing ring 5 is fixed to the inner wall of the close-fitting tube 32 by gluing. When the close-fitting tube 32 When sleeved on the outer wall of the first reducer 22, the sealing ring 5 will be slightly compressed to fill the gap between the close-fitting tube 32 and the first reducer 22. When the throat clamp 4 is sleeved on the outer wall of the close-fitting tube 32, the close-fitting tube 32 will be squeezed, thereby further squeezing the sealing ring 5, so that the sealing ring 5 fills the gap between the close-fitting tube 32 and the first reducer 22 more densely, so that the exhaust gas will not be discharged from the gap between the close-fitting tube 32 and the first reducer 22. Similarly, during long-term use, even if the throat clamp 4 becomes slightly loose, smoke leakage will not occur due to the filling of the sealing ring 5, thereby achieving a sealing effect. By reducing the size of the close-fitting tube 32 and the first reducer 22, it can be prevented that the size of the connection part becomes larger due to the installation of the sealing ring 5, thereby affecting the installation of other components.

[0031] Specifically, a support member for supporting the first reducer 22 is provided inside the first reducer 22, and the support member is used to prevent the first reducer 22 from being deformed due to extrusion by the throat clamp 4. The support member includes a support frame 6, and the support frame 6 is cross-shaped and consists of two triangular prisms.

[0032] Furthermore, the delivery pipe 21, the first reducer 22 and the support frame 6 are all made of stainless steel. The end of the support frame 6 is fixed to the inner wall of the first reducer 22 by welding. The triangular end of the support frame 6 faces the direction of the delivery pipe 21, so that the airflow can be diverted without blocking the airflow, thereby reducing the influence of the support frame 6 on the exhaust. The support frame 6 supports the first reducer 22, so that when the throat clamp 4 squeezes the close-fitting tube 32, the close-fitting tube 32 squeezes the sealing ring 5, and the sealing ring 5 squeezes the first reducer 22, the first reducer 22 will not be seriously deformed.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
