Description

Technical Field

For example, in the prior art, the patent application with application number "CN202121766466.4" applies for "a plunger sleeve for automobile parts with strong pressure resistance". The patent is provided with an inner sleeve layer, a support layer and an outer sleeve layer, and a pressure-resistant structure is provided inside the outer sleeve to improve the pressure resistance of the plunger sleeve.

At the same time, the high temperature resistance and thermal conductivity of the current plunger sleeve are not very obvious. Therefore, it is necessary to design an automobile plunger sleeve that is easy to install. Utility Model Content
