Description

Technical Field

[0001] This utility model belongs to the field of motorcycle exhaust pipe technology, and particularly relates to a self-locking motorcycle exhaust pipe. Background Technology

[0002] Motorcycle exhaust pipes are pipes connected to the engine exhaust port, used to expel exhaust gases produced by the engine. They play an important role in the performance, sound, and appearance of a motorcycle. Publication number CN219622767U discloses a motorcycle anti-scalding exhaust pipe, including an exhaust pipe with an inner ring of an annular baffle fixed to one end. The annular baffle has symmetrically arranged positioning holes. A fixing block is symmetrically fixed to one side of the annular baffle, and each fixing block has a fixing hole. The other side of the annular baffle contacts one end of an annular heat-absorbing plate. The inner side of the annular heat-absorbing plate contacts the outer wall of the exhaust pipe. The outer side of the annular heat-absorbing plate is fixed to the inner side of a protective sleeve. A mounting block is symmetrically fixed to one end of the protective sleeve, and each mounting block has a mounting hole. The mounting blocks pass through the positioning holes and are fixed to the fixing blocks by mounting bolts, which are respectively engaged in the fixing holes and mounting holes. The protective sleeve has an annular locking groove. This utility model protects the end of the exhaust pipe more comprehensively by using an end protection component, preventing burns to the user. While this type of exhaust pipe helps prevent users from being burned, it is lacking in terms of disassembly and assembly of the heat insulation panel. Because this type of exhaust pipe does not have a structure for quick disassembly and assembly of the heat insulation panel, when it is necessary to replace the heat insulation panel or maintain the exhaust pipe, the user needs to use disassembly tools to disassemble it, which not only reduces the disassembly efficiency but also may cause the user to be burned by the exhaust pipe during disassembly.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0029] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0030] In one embodiment of this utility model, such as Figure 1-4 As shown, a self-locking motorcycle exhaust pipe is provided, including an exhaust pipe body 1, a tail plate 2, and a heat insulation plate 3. A limit block 4 is fixedly installed on the surface of the exhaust pipe body 1. A slide rod 5 is slidably connected inside the limit block 4. A spring 6 is sleeved on the surface of the slide rod 5. A locking block 7 is fixedly installed on the surface of the slide rod 5. A heat dissipation plate 8 is fixedly installed on the surface of the exhaust pipe body 1. A heat dissipation fin 9 is fixedly installed on the surface of the heat dissipation plate 8. A limit groove 10 is opened on the surface of the heat insulation plate 3. An insertion hole 11 is opened through the surface of the heat insulation plate 3. A slider 12 is slidably connected in the insertion hole 11.

[0031] In this embodiment of the self-locking motorcycle exhaust pipe, when the heat insulation plate 3 needs to be disassembled, simply press the slider 12. The slider 12 will drive the locking block 7 to slide in the insertion hole 11. After the locking block 7 slides out of the insertion hole 11, the heat insulation plate 3 can slide out of the limiting block 4 through the limiting groove 10. When the heat insulation plate 3 needs to be installed, simply insert the heat insulation plate 3 into the limiting block 4 through the limiting groove 10. When the insertion hole 11 moves to the locking block 7, the locking block 7 and the sliding rod 5 will be springed by the spring force of the spring 6 to lock the locking block 7 into the insertion hole 11. The locking block 7 will drive the slider 12 to slide out of the insertion hole 11. At this time, the installation of the heat insulation plate 3 is completed. The heat dissipation plate 8 and heat dissipation fin 9 improve the heat dissipation efficiency of the exhaust pipe body 1. The heat insulation plate 3, sliding rod 5, locking block 7, limiting block 4, limiting groove 10, slot and sliding rod 5 are all included. Block 12 facilitates the disassembly and assembly of the heat insulation plate 3, avoiding the need for disassembly tools and reducing the risk of burns during disassembly. When the muffler body 15 needs to be disassembled and maintained, simply rotate the insert 16 until it rotates out of the fixing hole 14, then pull it out. After pulling out the insert 16, slide the tail plate 2 off the fixing plate 13. After the tail plate 2 slides out, rotate the muffler body 15 until it rotates out of the tail plate 2, thus completing the disassembly of the muffler body 15. The fixing plate 13, fixing hole 14, insert 16, and muffler body 15 not only reduce noise in the exhaust pipe but also facilitate the disassembly and maintenance of the muffler body 15, thereby improving the maintenance efficiency of the muffler body 15.

[0032] In another embodiment, such as Figure 1-4 As shown, one end of the spring 6 is connected to the surface of the locking block 7, and the other end is connected to the inner surface of the limiting block 4. Specifically, the spring 6 is designed to drive the locking block 7 into the insertion hole 11, thereby fixing the heat insulation plate 3 onto the limiting block 4.

[0033] In another embodiment, such as Figure 1-4 As shown, the surfaces of the locking block 7 and the slider 12 that come into contact with each other are curved, and the locking block 7 is slidably connected to the insertion hole 11. Specifically, the curved design of the locking block 7 and the slider 12 facilitates the installation and removal of the heat insulation plate 3, thereby avoiding the need for disassembly tools when installing or removing it.

[0034] In another embodiment, such as Figure 1-4 As shown, the limiting block 4 and the limiting groove 10 are slidably connected, and the heat sink 8 and the heat sink 9 are both made of copper. Specifically, the sliding design of the limiting block 4 and the limiting groove 10 serves to limit the heat insulation plate 3 during installation, while the copper material of the heat sink 8 and the heat sink 9 improves the heat dissipation efficiency of the exhaust pipe body 1.

[0035] In another embodiment, such as Figure 1-4 As shown, the tail plate 2 and the fixing plate 13 are slidably connected, and the muffler body 15 is threadedly connected to the tail plate 2. Specifically, the sliding design of the tail plate 2 and the fixing plate 13 serves to limit the tail plate 2, while the threaded connection between the muffler body 15 and the tail plate 2 facilitates the disassembly and maintenance of the muffler body 15.

[0036] In another embodiment, such as Figure 1-4 As shown, the insert 16 and the fixing hole 14 are connected by threads. Specifically, the threaded connection design between the insert 16 and the fixing hole 14 facilitates the disassembly and assembly of the tail plate 2.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
