The easy-to-install automobile exhaust pipe provided by the utility model can be quickly installed when the exhaust pipe is installed, thereby saving installation time and improving installation efficiency, and can be used in conjunction with the components in the shock-absorbing assembly, so that the exhaust pipe can be damped when vibration occurs, thereby ensuring the stability of the connection.

[0004] It can be seen from the above technology that the current exhaust pipe is integrated, and is connected to the exhaust port of the car through bolts and the connecting plate of the exhaust pipe. Therefore, the later replacement and maintenance need to be completed by installing and removing the bolts, which is still relatively inconvenient. Secondly, the vibration generated by the exhaust pipe during the driving of the car can be reduced by the shock absorbing assembly, but it is not convenient to reduce the vibration generated by the exhaust pipe when exhausting, so there is room for improvement. Utility Model Content

[0005] The utility model provides a high temperature resistant automobile exhaust pipe which is easy to install, so as to solve the problems raised in the background technology.

[0006] In order to solve the above problems, the utility model provides a high temperature resistant automobile exhaust pipe which is easy to install, comprising an exhaust pipe, a protective tube, and a shock absorbing assembly.

The protective tube is sleeved in the exhaust pipe, and one end of the protective tube conflicts with the positioning ring. A positioning rod for inserting the positioning hole is fixedly provided in the end surface of the protective tube that conflicts with the positioning ring. A connecting seat is fixedly provided at the middle end of the outer surface of the protective tube. The shock absorbing assembly is composed of a mounting frame, a shock absorbing spring, a shock absorbing rod, and a T-shaped connector. The mounting frame is fixedly installed on the bottom of the automobile. A shock absorbing spring is provided in the mounting frame. The top end of the shock absorbing spring is fixedly connected to the top of the mounting frame, the bottom end of the shock absorbing spring is fixedly connected to the top end of the shock absorbing rod, the bottom end of the shock absorbing rod passes through the mounting frame, and the end extends to the outer bottom of the mounting frame. The top of the T-shaped connector is fixedly connected to the bottom end of the shock absorbing rod, the T-shaped connector is plugged into the connecting seat, and the connecting head is fixedly connected to the connecting seat by bolts.

[0007] Preferably, a flange is threadedly connected to the front end of the exhaust pipe, and the exhaust pipe is connected to the exhaust port of the automobile through the flange and bolts.

[0008] Preferably, two arc-shaped clamping plates are symmetrically arranged in the upper and lower parts of the protective tube, and the top of the arc-shaped clamping plates is connected to the inner wall of the protective tube through a plurality of springs.

[0009] The beneficial effects of adopting the above technical solution are:

[0010] 1. Through the threaded connection between the flange and the exhaust pipe, the flange is connected to the exhaust port of the car, which can facilitate the subsequent loading and unloading of the exhaust pipe after the first installation. There is no need to remove the flange. The exhaust pipe can be loaded and unloaded in the flange by simply rotating the exhaust pipe, thereby improving the convenience of installation.

[0011] 2. The protective tube can form a protection for the outside of the exhaust pipe. At the same time, the spring and the arc-shaped clamping plate can effectively clamp the surface of the exhaust pipe. The positioning rod and the positioning hole in the positioning ring can make the protective tube stably connected to the exhaust pipe. When the exhaust inside the exhaust pipe vibrates, the arc-shaped clamping plate and the spring can be used to reduce the vibration of the exhaust pipe.

[0012] 3. The shock-absorbing assembly is used to absorb the vibration generated by the exhaust pipe during the driving of the car. The shock-absorbing assembly provides a fixed position for the protective tube. The T-shaped connector in the shock-absorbing assembly is plugged into the connecting seat, and the bolts make it easy to load and unload the T-shaped connector and the connecting seat, thereby making it easy to load and unload the exhaust pipe.
