Description

Technical Field

[0001] The utility model belongs to the technical field of motorcycle mufflers, in particular to a durable motorcycle muffler. Background Art

[0002] The motorcycle muffler is used to reduce the noise generated by the engine exhaust and the harmful substances emitted by the exhaust gas. It is usually located at the end of the exhaust pipe, guiding the exhaust gas out of the vehicle and reducing its noise level. The motorcycle muffler with publication number CN213838734U includes a muffler body and an exhaust pipe body. The exhaust pipe body and the inner side wall of the muffler body are threadedly connected. A baffle is fixedly connected to the inner side wall of the muffler body, and the end face of the exhaust pipe body can contact the baffle. When this technical solution is adopted, it is easy to improve the installation accuracy of the muffler. Although this type of motorcycle muffler has the effect of improving the installation accuracy of the muffler, it is lacking in terms of the durability of the muffler. Since this type of muffler does not have the function of dissipating heat to the main body, the temperature of the muffler will increase as the exhaust gas in the exhaust pipe is continuously discharged during long-term driving. The long-term high temperature and frequent vibration of the muffler may cause the internal parts of the muffler to loosen or fatigue and break, thereby reducing its life. Utility Model Content

[0026] The following describes the embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. Figure 1-4 The described embodiments are exemplary and are intended to explain the embodiments of the present invention, but should not be understood as limiting the present invention.

[0027] In the description of the embodiments of the present invention, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the embodiments of the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0028] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0029] In one embodiment of the present invention, Figure 1-4As shown, a durable motorcycle muffler is provided, including an exhaust pipe 1 and a muffler body 5, a tail plate 2 is fixedly installed on the surface of the exhaust pipe 1, a limit block 3 is fixedly installed on the inner surface of the tail plate 2, a limit hole 4 is provided on the surface of the limit block 3, a slot 6 is provided on the surface of the muffler body 5, a ring 7 is rotatably connected to the surface of the muffler body 5, a limit rod 8 is fixedly installed on the surface of the ring 7, a heat conducting plate 9 is fixedly installed on the inner surface of the exhaust pipe 1, a heat dissipation plate 10 is fixedly installed on the surface of the heat dissipation plate 10, a heat dissipation fin 11 is fixedly installed on the surface of the heat dissipation plate 10, and a heat dissipation hole 12 is provided on the surface of the heat dissipation fin 11.

[0030] The durable motorcycle muffler of the embodiment of the present utility model only needs to align the limiting rod 8 with the limiting hole 4 and insert it when the muffler body 5 needs to be installed. After the limiting rod 8 is inserted into the limiting hole 4, the muffler body 5 is rotated through the slot 6. After the muffler body 5 is connected to the limiting block 3 through a thread, the installation of the muffler body 5 is completed. During the driving of the motorcycle, the temperature inside the exhaust pipe 1 will be introduced into the heat conducting plate 9, and the heat conducting plate 9 will transfer the heat to the heat dissipation plate 10 and the heat dissipation fins 11. At this time, the airflow will dissipate heat to the heat dissipation plate 10 and the heat dissipation fins 11, thereby avoiding the situation where heat accumulates in the exhaust pipe 1 and causes the temperature of the muffler to rise. The heat conducting plate 9, the heat dissipation plate 10, the heat dissipation fins 11 and the heat dissipation holes 12 have the effect of dissipating heat inside the exhaust pipe 1. The effect is achieved, thereby avoiding the situation where the internal parts of the muffler body 5 are loosened or fatigued and fractured under high temperature and frequent vibration environments, thereby improving the service life of the muffler body 5. When the heat insulation board 13 needs to be installed, it is only necessary to insert the heat insulation board 13 on the slider 14 through the slide groove 17, and then the inserting strip 16 slides to the fixing hole 15 and then connects the inserting strip 16 to the fixing hole 15 through a thread. After connecting the inserting strip 16, the installation of the heat insulation board 13 is completed. The slider 14, the heat insulation board 13, the slide groove 17, the fixing hole 15 and the inserting strip 16 prevent the driver's legs from being burned by the exhaust pipe 1 during driving or parking, and also facilitate the disassembly and assembly of the heat insulation board 13, thereby improving driving safety and the installation efficiency of the heat insulation board 13.

[0031] In another embodiment, Figure 1-4 As shown, the muffler body 5 and the limiting block 3 are connected by threads, and the limiting rod 8 is slidably connected to the limiting hole 4. Specifically, the threaded connection design of the muffler body 5 and the limiting block 3 facilitates the user to disassemble and assemble the muffler body 5, thereby facilitating cleaning and maintenance of the muffler body 5, while the sliding design of the limiting rod 8 and the limiting hole 4 limits the position of the muffler body 5 when the muffler body 5 is installed.

[0032] In another embodiment, Figure 1-4As shown, the ring 7 is slidably connected to the tail plate 2. Specifically, the sliding design of the ring 7 and the tail plate 2 has the effect of limiting the position of the muffler body 5 when the muffler body 5 is installed.

[0033] In another embodiment, Figure 1-4 As shown, the heat sink 11 is shaped like a fin, and the heat conducting plate 9, the heat sink 10, and the heat sink 11 are all made of copper. Specifically, the fin-shaped design of the heat sink 11 increases the contact area between the heat sink 11 and the airflow, thereby improving the heat dissipation effect of the heat sink 10. The strong thermal conductivity of copper allows the high temperature inside the exhaust pipe 1 to be conducted out of the exhaust pipe 1, thereby preventing the temperature of the muffler body 5 from rising.

[0034] In another embodiment, Figure 1-4 As shown, the slider 14 is slidably connected to the chute 17, and the fixing hole 15 is threadedly connected to the insert 16. Specifically, the sliding design of the slider 14 and the chute 17 serves to limit the position of the insulation board 13 during installation, while the threaded connection design of the insert 16 and the fixing hole 15 facilitates the disassembly and cleaning of the insulation board 13.

[0035] In another embodiment, Figure 1-4 As shown, the heat insulation board 13 is made of ceramic fiber. Specifically, ceramic fiber is a non-metallic heat insulation material with excellent heat insulation performance and high temperature tolerance, thereby preventing the driver from being burned by the exhaust pipe 1.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
