High-temperature-resisting protection casing pipe of car part

Abstract

The invention discloses a high-temperature-resisting protection casing pipe of a car part. The casing pipe is characterized by comprising a pipe body, a high-temperature-resisting layer and anti-falling ribs, the high-temperature-resisting layer is bonded in the pipe body, the two or more anti-falling ribs are arranged at the position, close to a port, of the pipe body of the protection casing pipe internally provided with the high-temperature-resisting layer, the outer surface of the pipe body is coated with a high-temperature-resisting buffer ring, and threads are mounted on the outer surface of the buffer ring. The protection casing pipe is made of fluoroether rubber, the thickness of the casing pipe ranges from 2 mm to 3 mm, the casing pipe can resist high temperature, and is stable inquality, the anti-falling ribs are simple in structure and can prevent falling, the outer surface of the pipe body is coated with the high-temperature-resisting buffer ring, the pipe body is not prone to heating aging, meanwhile, oil resistance and heat stability are good, a car metal hard pipe and other parts can be effectively protected, and the casing pipe has the advantages of being simple instructure, low in machining cost, high in production efficiency and the like.

Description

technical field [0001] The invention belongs to the technical field of auto parts, in particular to a high temperature resistant sheath tube of auto parts. Background technique [0002] In the prior art, because the space around the automobile engine is small, there is not too much gap between other parts such as metal oil guide pipes and rubber hoses connected to the automobile engine, which easily causes unnecessary safety accidents. In order to prevent the wear and tear of metal hard pipes, rubber hoses and other parts on the automobile engine, the sheath tube made of rubber plays a certain role in protecting the metal hard pipes, rubber hoses and other parts. There is a high surface temperature of the automobile engine when it is working, so that the temperature of the metal hard pipe and other parts connected to the engine rises, which is easy to cause the sheath tube sleeved on the hard pipe and other parts to be damaged due to high temperature. And aging or expansion...

AI Technical Summary

Problems solved by technology

There is a high surface temperature of the automobile engine when it is working, so that the temperature of the metal hard pipe and other parts connected to the engine rises, which is easy to cause the sheath tube sleeved on the hard pipe and other parts to be damaged due to high temperature. And aging or expansion, thereby shortening the service life of the sheath tube and other technical problems

In addition, the inner wall of the protective casing for auto parts in the prior art is often relatively smooth. When driving on a road with poor road conditions, the strong bumps of the car will cause the protective casing to fall off, thereby causing damage to some parts and causing unnecessary damage. Due losses may even lead to accidents
