Technical Field
[0001] The utility model relates to the technical field of muffler carriers, in particular to a collision-proof automobile muffler hook. Background Art
[0002] Automobile muffler is a part used to reduce the noise generated by the engine of a motor vehicle. Since the difference in the length of the two pipes is equal to half the wavelength of the sound waves emitted by the car, the two sound waves interfere with each other when superimposed, thus reducing the sound intensity and making the sound smaller, thus achieving the effect of silencing.
[0003] When the existing automobile muffler is installed on the bottom of the vehicle, it needs to be loaded and fixed with a hook. Most of the existing muffler hooks are simple U-shaped plates. The muffler is placed in the U-shaped plate, and then the U-shaped plate is fixed to the bottom of the vehicle. However, in actual use, the hook cannot protect the bottom of the muffler. When the vehicle is driving, the protruding stones on the road surface are likely to impact the bottom of the muffler, which can easily cause the muffler to be damaged and affect the service life of the muffler. Therefore, we propose an anti-collision automobile muffler hook. Utility Model Content

[0029] In actual use, the muffler is first placed in the inner cavity of the fixed shell 1, and then the fixed shell 1 is fixedly installed on the bottom of the vehicle. When in use, when there are protruding stones at the bottom of the vehicle, the stones will first act on the bottom of the second buffer plate 3, and then the first limit slider 16 will stretch and compress the first damper 17, so that preliminary buffering can be achieved in the moving direction of the vehicle, and then the second buffer plate 3 will be driven to push the connecting rod 34, so that the connecting rod 34 pushes the second damper 33 to achieve buffering again, thereby achieving all-round buffering, improving the buffering protection effect, and preventing the muffler from being damaged by impact;
