Description

Technical Field

[0001] This utility model relates to the field of automotive exhaust pipe technology, and in particular to an automotive exhaust pipe that is easy to assemble. Background Technology

[0002] The exhaust pipe is an important component of the car's exhaust system.

[0003] The structure of the automotive exhaust pipe can be referenced in the utility model patent application "CN214118298U", which discloses "an easily disassembled automotive exhaust pipe tailpipe installation structure". This design features a two-section tailpipe assembled using snap-fit ​​mechanisms, facilitating individual disassembly and cleaning. It is simple and easy to use. Furthermore, it reduces the need for repairs and replacements when the exhaust pipe tailpipe is damaged. The improved design of the curved section at the tailpipe end allows for independent disassembly and better cleaning. This addresses the problem that the tailpipe section of a typical automotive exhaust pipe is integrated with the main body, resulting in a fixed structure that allows dust to accumulate on the inner wall during exhaust processes, affecting exhaust efficiency.

[0004] However, the simple threaded connection between the tailpipe assembly and the exhaust pipe results in relatively weak stability after connection. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an easy-to-assemble automotive exhaust inner pipe.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

The tailpipe assembly is threadedly connected to the limiting ring. A fixing ring seat is installed at the end of the exhaust pipe body outside the connecting pipe. An auxiliary fixing component is sleeved on the outer wall of the tailpipe assembly and is threadedly connected to the fixing ring seat.

[0008] Furthermore, in a preferred configuration, a retaining ring is fixedly fitted onto one side of the outer wall of the tailpipe assembly. The retaining ring has a first external thread on its outer wall, and its outer diameter is larger than that of the limiting ring. A T-shaped ring is also fixedly fitted onto the outer wall of the tailpipe assembly on one side of the retaining ring.

[0009] Furthermore, in a preferred configuration, the auxiliary fixing component includes a fixing ring, a locking cavity is provided inside the fixing ring at the T-shaped ring, four connecting rods are arranged in a ring at equal intervals on the outer wall of the fixing ring, one side of the connecting rod is connected to an installation ring, and the outer wall of the installation ring is provided with a second external thread.

[0011] In addition, a preferred structure is that a limiting groove is opened in the connecting pipe at the tail pipe assembly, a sealing ring gasket is provided inside the limiting groove, and a limiting ring is fixedly sleeved on one side of the connecting pipe. Multiple limiting blocks are arranged in a ring at equal intervals on one side of the limiting ring, and the limiting blocks are pentagonal prisms.

[0012] In addition, a preferred structure is that a slot is provided on one side of the tailpipe assembly at the limiting insert.

[0013] Furthermore, in a preferred configuration, a through hole is provided inside the limiting ring at the tube, and a cavity is provided on one side of the limiting ring at the limiting ring. A first internal thread is provided inside the cavity at the first external thread, and the first internal thread is threadedly connected to the first external thread.

[0014] The beneficial effects of this utility model are as follows:

[0015] In this utility model, by using a limiting ring in conjunction with the exhaust pipe body and tailpipe assembly, the exhaust pipe body and tailpipe assembly are detachable. When the tailpipe assembly is damaged or malfunctions, it can be disassembled for repair without the need for complete replacement. Furthermore, by using an auxiliary fixing component in conjunction with a fixing ring seat, the stability of the exhaust pipe body and tailpipe assembly after connection can be enhanced.
