High-temperature-resistant protective casing of automobile part

Abstract

The invention discloses a high-temperature-resistant protective casing of an automobile part. The high-temperature-resistant protective casing is characterized in that the protective casing comprises a casing body, a high-temperature-resistant layer and anti-falling ribs. The high-temperature-resistant layer is bonded into the casing body, and two or more anti-falling ribs are arranged in the position, close to ports, of the casing body of the protective casing internally provided with the high-temperature-resistant layer. The outer surface of the casing body is wrapped with a high-temperature-resistant buffer ring, and a thread is arranged on the outer surface of the buffer ring. The protective casing is made of fluoroether rubber, is 2-3 mm thick and is high-temperature resistant and stable in quality; the anti-falling ribs are simple in structure and can prevent falling; the outer surface of the casing body is wrapped with the high-temperature-resistant buffer ring, so that the casing body is not prone to aging due to heating and is good in oil resistance and thermal stability, and an automobile metal hard pipe and other parts can be protected more effectively. The high-temperature-resistant protective casing has the advantages of being simple in structure, low in processing 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
