[0002] A sports motorcycle is also called a racing motorcycle. The main design concept is for people to use for leisure and vacation. It is an interesting means of transportation and also a recreational tool to experience the joy of life. The exhaust pipe is a part of the engine exhaust system. The exhaust system mainly includes an exhaust manifold, an exhaust pipe, and a muffler. Generally, a three-way catalytic converter for controlling engine pollutant emissions is also installed in the exhaust system. The exhaust pipe generally includes a front exhaust pipe and a rear exhaust pipe. A muffler is a device that blocks the propagation of sound and allows the airflow to pass through, which is an important measure to eliminate aerodynamic noise. A muffler is a noise reduction device installed on the airflow passage of an aerodynamic device or in the intake and exhaust systems.
[0003] For the existing heat insulation device of a motorcycle muffler, usually when using a motorcycle, a large amount of heat will be generated on the exhaust muffler of the motorcycle. The heat insulation device can prevent the driver from touching the muffler and being scalded. However, after the device is installed and used, the heat diffusion effect between the inner side and the muffler is poor, and it is impossible to effectively use the airflow to quickly diffuse during the motorcycle driving process. Therefore, a heat insulation device for a motorcycle muffler is proposed for the above problems. Content of the Utility Model
[0004] The purpose of the utility model is to provide a heat insulation device for a motorcycle muffler to solve the above problems.

A heat insulation device for a motorcycle muffler includes a fish-shaped plate, and is characterized in that: air flow holes are distributed on the surface of the fish-shaped plate; a plurality of counterbores are provided on the fish-shaped plate; a rubber pad is installed at the orifice inside each counterbore; a side hoop shock-absorbing member is provided between the two rubber pads, and a contact concave surface is provided in the middle of the surface of the side hoop shock-absorbing member.
[0006] Preferably, the air flow holes are in a state of being inclined at 30°.
[0007] Preferably, the contact concave surface is in contact with the corresponding surface of the external muffler.
[0008] Preferably, the counterbores are fixedly connected to the corresponding connection parts of the external muffler through connecting bolts.
[0009] Preferably, the shape of the fish-shaped plate is consistent with the shape of the corresponding part of the external muffler.
[0010] Preferably, both ends of the side hoop shock-absorbing member are fixedly welded to the corresponding parts on the inner side of the fish-shaped plate.
[0011] Compared with the prior art, the advantages of the present utility model are as follows: A plurality of air flow holes distributed on the fish-shaped plate at an inclination angle form a guiding air flow, and in combination with the fact that there is a spacing between the fish-shaped plate and the motorcycle muffler through the side hoop shock-absorbing member, the diffusion intensity of part of the heat of the muffler is enhanced, and the shock-absorbing effect of the overall structural connection is improved.
