Anti-vibration fastening type exhaust pipe

Abstract

The invention discloses an anti-vibration fastening type exhaust pipe, which comprises a fixed part arranged on the bottom part of an automobile chassis, and an exhaust pipeline fastened into the fixed part. A swallowtail-shaped fastening groove is formed in the bottom part of the fixed part; a swallowtail-shaped fastening block connected with the fastening groove in a matching way is arranged onthe top part of the exhaust pipeline; a loss-prevention block abuts against inside an arc-shaped groove; a cooling pipe and multiple mufflers are arranged in the exhaust pipeline; electroplated layersare arranged on inner surfaces and outer surfaces of the mufflers; and anti-oxidation layers are arranged on surfaces of the electroplated layers, and are obtained through coating antioxidant combination coatings on the surfaces of the electroplated layers. The vibration of the exhaust pipe caused by the vibration of an automobile is prevented, the exhaust pipe is longer in service life and moreconvenient to fix, and after cooled tail gas passes through the mufflers, the effects on reducing vibration and reducing noise are achieved; and the occurrence of the phenomenon that the exhaust pipeis corroded can be effectively prevented.

Description

technical field [0001] The invention belongs to the technical field of exhaust pipe equipment, and in particular relates to an anti-shock snap-fit ​​exhaust pipe. Background technique [0002] With the continuous development of my country's economy, motor vehicles have become very popular: automobiles have entered thousands of households, and motor vehicles are also widely used in industry and agriculture. With the continuous development of our country's economy, motor vehicles have become very popular. Now almost every family has a car. When people choose a car, they not only pay attention to the appearance of the car, but also attach great importance to the safety, stability and environmental awareness of the car. In recent years, urban motor vehicles have grown rapidly, and the phenomenon of environmental pollution caused by traffic noise has become increasingly prominent. In addition, most of the existing automobile exhaust pipes are single-structure exhaust pipe bodies...

AI Technical Summary

Problems solved by technology

In addition, most of the existing automobile exhaust pipes are single-structure exhaust pipe bodies, through which the pipe body is docked with the automobile engine to complete the exhaust work. The exhaust pipe is connected to the automobile engine through connectors without other fixed facilities , when the car is subjected to a large vibration, it will cause the exhaust pipe to vibrate, which will affect the exhaust function and the service life of the exhaust pipe

The survey shows that the exhaust pipe has not yet reached a sufficient temperature, and the condensed water produced has not been evaporated and remains in the exhaust pipe, especially the muffler, while water and sulfur dioxide, nitrogen dioxide, etc. When the gas is combined, it will produce acid, which will corrode the exhaust pipe and make it easy to rust and damage, and the rusted automobile exhaust pipe is not easy to clean and damages the appearance
