Description

Technical Field

[0001] This utility model belongs to the field of automotive exhaust tip technology, specifically a multifunctional automotive exhaust tip. Background Technology

[0002] The exhaust pipe, also known as the tailpipe, is used in automobiles. As society develops and people's demands for quality of life increase, the exhaust pipe effectively discharges the exhaust gases produced by the engine into the air. As the exhaust gases are discharged through the exhaust pipe, the engine temperature is effectively reduced, and damage to the engine caused by the exhaust gases is avoided, thus extending the engine's service life.

[0003] A search revealed a utility model patent with publication number CN215333073U and publication date of 2021-12-28, entitled "A Waterproof One-Way Automotive Exhaust Throat." While this patent addresses the issue of "adjusting the sealing plate by using a support plate, telescopic rod, compression spring, and sealing plate; when exhausting, the pressure of the exhaust pushes the sealing plate into the exhaust groove, thus expelling the exhaust gas; when not exhausting, the compression spring and telescopic rod pull the sealing plate back to its original position, improving the waterproof sealing effect and increasing the practicality of the automotive exhaust throat," the patent also mentions a limiting groove and limiting block to restrict the sealing plate. The adjustable position of the sealing plate prevents it from excessively protruding outwards, affecting the exhaust performance of the exhaust pipe and increasing its safety. The inclusion of a water baffle in conjunction with the housing further prevents water from entering the exhaust pipe, achieving better waterproofing. However, in actual use, a large amount of dust accumulates on the protective mesh of the exhaust pipe. If the mesh cannot be replaced promptly, excessive dust buildup can clog the vents, affecting exhaust emissions. The water baffle only blocks some water; when driving over flooded roads, water splashes into the exhaust pipe and cannot drain quickly enough, leading to rust and affecting its use. Therefore, it does not achieve the desired effect. Summary of the Invention

[0004] To address the problems existing in the background technology, this utility model provides a multifunctional automotive exhaust tip.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a multifunctional automobile exhaust tip, comprising a housing, a connecting pipe, a rotating ring, a baffle plate, a mesh plate, an annular cover, two clamping mechanisms, and multiple funnels;

[0006] One end of the housing is connected to the connecting pipe, and clamping mechanisms are respectively provided on both sides of the connecting pipe. The two clamping mechanisms are hinged to one end of the housing and are symmetrically arranged. The inner wall of the rotating ring is provided with an internal thread, and both clamping mechanisms are threadedly connected to the rotating ring. The outer wall of the other end of the housing is provided with an external thread. The annular cover is provided with an internal thread, and is threadedly connected to the housing. A mesh plate is provided between the annular cover and the housing. The mesh plate is fixed by the annular cover. Multiple drainage holes are evenly distributed along the length direction at the bottom of the inner end of the housing. Each drainage hole is provided with a funnel, and a baffle plate is provided on one of the funnels adjacent to the mesh plate.

[0007] Compared with the prior art, the beneficial effects of this utility model are: the mesh plate can be removed by rotating the ring cover, which is simple to operate and easy to replace; the water in the shell is drained out of the drain hole through the funnel, which prevents water from remaining in the shell, avoids rusting, and improves service life; the exhaust pipe is clamped and fixed by two clamping mechanisms, and by rotating the ring, the two clamping mechanisms are made to fit the exhaust pipe better, which improves the fixing effect and makes disassembly convenient and quick.

[0009] Figure 2 This is a schematic diagram showing the positional relationship between the mesh plate and the annular cover of this utility model. Detailed Implementation

[0010] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0011] This embodiment describes a multifunctional automobile tailpipe, including a housing 1, a connecting pipe 2, a rotating ring 6, a baffle plate 8, a mesh plate 9, an annular cover 10, two clamping mechanisms, and multiple funnels 7.

[0012] One end of the housing 1 is connected to the connecting pipe 2. Clamping mechanisms are provided on both sides of the connecting pipe 2. The two clamping mechanisms are hinged to one end of the housing 1 and are symmetrically arranged. The inner wall of the rotating ring 6 is provided with an internal thread. Both clamping mechanisms are threaded to the rotating ring 6. The outer wall of the other end of the housing 1 is provided with an external thread. The annular cover 10 is provided with an internal thread. The annular cover 10 is threaded to the housing 1. A mesh plate 9 is provided between the annular cover and the housing 1. The mesh plate 9 is fixed by the annular cover 10. Multiple drainage holes are evenly distributed along the length direction at the bottom of the inner end of the housing 1. Each drainage hole is provided with a funnel 7. A baffle plate 8 is provided on one of the funnels 7 adjacent to the mesh plate 9.

[0013] Each of the clamping mechanisms includes a fixed plate 3, a telescopic plate 4, and a plurality of compression springs 5;

[0014] The outer wall of the fixing plate 3 is provided with external thread 2. The fixing plate 3 is threadedly connected to the rotating ring 6. The inner wall of the fixing plate 3 is provided with a groove. A telescopic plate 4 is slidably provided in the groove. The telescopic plate 4 is fixedly connected to one end of a plurality of compression springs 5. The other end of the plurality of compression springs 5 ​​is fixedly connected to the bottom end of the groove.

[0015] When using this utility model, the connecting pipe 2 is inserted into the exhaust pipe of the car. The pressure from the outer wall of the exhaust pipe compresses the telescopic plate 4 on each clamping mechanism into the groove of the fixed plate 3. The rotating ring 6 is rotated to limit and fix the two clamping mechanisms. When liquid water condenses inside the housing 1 or water splashes onto the housing 1 and needs to be discharged, the water flows out through the funnel 7 to the drain hole. When the screen plate 9 needs to be replaced, the annular cover 10 is rotated to remove and replace the screen plate 9 directly. The operation is simple and quick.

[0016] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of the equivalents of the claims are intended to be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
