Abstract

A reinforced connection structure between a metal insert and a plastic part. It is composed of a plastic part and a metal insert. The inner section of the metal insert is cylindrical and embedded in the plastic part. At least one number of protrusions, or pits, or through holes, or thorns are provided in the circumferential direction, and any one of the protrusions, or pits, or through holes, or thorns is surrounded or filled by plastic parts. When the plastic part is injection molded, the plastic can pass through the hole or be filled into the pit, thereby increasing the joint surface between the metal insert and the plastic part, and the plastic part is located in the direction of the metal insert, effectively preventing the metal The insert is disengaged from the plastic part.

Description

Technical field: [0001] The invention relates to pipeline transportation technology, in particular to pipeline connectors, in particular to a reinforced connection structure between metal inserts and plastic parts. Background technique: [0002] In the prior art, pipeline connectors composed of metal inserts and plastic components are widely used in pipeline installation projects. During installation and use, there will be circumferential and axial forces between the metal insert and the plastic part, which will cause the metal insert to separate from the plastic part, affecting the sealing effect and safety of use. Invention content: [0003] The purpose of the present invention is to provide a reinforced connection structure between metal inserts and plastic parts. The reinforced connection structure between metal inserts and plastic parts needs to solve the problem of metal inserts and plastic parts in pipeline connectors in the prior art. Technical problems that disen...
