Example Embodiment

[0017] Such as figure 1 with 2 As shown, figure 1 It is a structural schematic diagram of a decorative tail pipe that prevents falling off proposed by the present invention, figure 2 It is a schematic diagram of a cross-sectional structure of a decorative tail pipe that prevents falling off proposed by the present invention.
[0018] Reference figure 1 with 2 , The present invention proposes a decorative tail pipe to prevent falling off, including: a decorative pipe and an exhaust tail pipe 2;
[0019] The decorative tube includes an inner tube body 11 and an outer tube body 12. The inner tube body 11 is located inside the outer tube body 12 and the inner tube body 11 is fixed with the outer tube body 12. The inner tube body 11 is provided with a clamping joint extending to the middle of the lumen The exhaust tail pipe 2 is inserted into the inner tube body 11 at one end, and the outer wall of the exhaust tail pipe 2 is provided with a positioning protrusion 21 matched with the clamping piece 13.
[0020] In the specific installation method of the decorative tail pipe to prevent falling off in this embodiment, the exhaust tail pipe is pre-welded on the automobile exhaust system, and one end of the inner pipe body is sleeved on the exhaust tail pipe, so that the clamping piece is away from the inner pipe body One end is clamped on the positioning protrusion to realize the clamping and fixing of the decorative pipe and the exhaust tail pipe.
[0021] In this embodiment, the proposed decorative tail pipe for preventing falling off includes an inner tube body and an outer tube body. The inner tube body is located inside the outer tube body and the inner tube body is fixed with the outer tube body. There is a clamping piece extending to the middle of the lumen, one end of the exhaust tail pipe is inserted into the inner tube body, and the outer wall of the exhaust tail pipe is provided with a positioning protrusion matched with the clamping piece. The decorative tail pipe designed to prevent falling off through the above-mentioned optimized design has reasonable structure design and simple process. By setting the clamping piece on the inner pipe body of the decorative pipe, the decorative pipe and the exhaust tail pipe are clamped and fixed, which is easy to install and can be installed without welding. Good fixation and stable mechanical strength, which can meet the severe vibration requirements of the vehicle during driving.
[0022] In the specific arrangement of the outer tube body, the outer tube body 12 includes a decorative section and an installation section connected in sequence, the inner tube body 11 is located in the installation section, and the exhaust tail pipe 2 is away from one end of the decorative section from the inner tube body 11 Inserted into the inner tube body 11.
[0023] In a further specific embodiment, one end of the decorative section away from the inner tube body 11 has a bending flange 3 that curves from the outer edge of the opening to the inside of the opening, so as to achieve an aesthetic effect.
[0024] In the specific implementation of the clamping piece, the clamping piece 13 extends away from the inner tube body 11 toward the decorative section, so that the exhaust tail pipe can be inserted into the inner pipe body, and after the clamping piece is locked with the positioning protrusion , Play a role in stopping retreat.
[0025] In order to facilitate the insertion of the tail pipe, in other specific embodiments, the clamping piece 13 has an arc-shaped structure with a middle part protruding in the direction of the mounting section to further improve the anti-return effect.
[0026] In the specific installation method of the clamping piece, the clamping piece can be processed separately and fixed to the inner wall of the inner pipe, or it can be integrally formed during the processing of the inner pipe, so as to facilitate the processing of the clamping piece and ensure the connection with the inner pipe. strength.
[0027] In order to further improve the connection reliability between the exhaust tail pipe and the inner pipe body after installation, the outer wall of the exhaust tail pipe 2 is also provided with a limiting protrusion 22 for limiting the position of the clamping piece 13, and the limiting protrusion 22 is located on the positioning protrusion. The protrusion 21 is far away from the side of the decorative section; by providing a limiting protrusion, after installation, the clamping piece is caught between the positioning protrusion and the limiting protrusion to further prevent the decorative tube from sliding off.
[0028] In the specific implementation of the positioning protrusions, the outer wall of the exhaust tail pipe 2 is provided with a plurality of positioning protrusions 21, and the plurality of positioning protrusions 21 are distributed along the extension direction of the exhaust tail pipe 2, according to the exhaust tail pipe extension of different vehicles. Out the length and adjust the card connection position.
[0029] In other specific embodiments of positioning protrusions, the inner tube body 11 is provided with a plurality of clamping pieces 13 distributed along the circumference, and the outer wall of the exhaust tail pipe 2 is provided with a plurality of positioning groups, and each positioning group includes separate and A plurality of positioning protrusions 21 matched with each of the clamping pieces 13; the plurality of clamping pieces can be clamped from multiple directions, which further improves the installation reliability.
[0030] The above are only preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited to this. Anyone familiar with the technical field within the technical scope disclosed by the present invention, according to the technical solution of the present invention Equivalent replacements or changes to its inventive concept should all fall within the protection scope of the present invention.
