Background technology
In a lot of plastic product, in order to install, the needs of connection etc., usually will place the part of some metalworks or other materials, these parts, be referred to as the inserts in plastic products in plastic.Be bumped in plastics inserts object or in order to increase plastic local strength, hardness, wearability, magnetic conductivity etc.; Or in order to improve precision, increase the stability of the size and dimension of plastic; Or in order to meet some property requirement to plastic.PPR inserts is a kind of common plastic insert, its inserts mainly metal material, but in use easily there is drainage in this PPR inserts, reason is that the bonding strength of plastics and metal insert is inadequate, and the bonding strength of plastics and metal insert and product structure, mould, Shooting Technique, materials etc. are relevant.Though the preventing water leakage performance of PPR inserts can be improved by adjusting process, but the poor stability of Shooting Technique, easily by the impact of the objective factors such as time, place, weather, therefore want fundamentally to improve PPR inserts drainage by process aspect more difficult.
Utility model content
The utility model, for overcoming at least one defect (deficiency) described in above-mentioned prior art, provides a kind of and carries out improving from structure thus effectively increase the plastic pipe insert structure of the bonding strength between working of plastics and metal insert.
For solving the problems of the technologies described above, the technical solution of the utility model is as follows:
A kind of plastic pipe insert structure, comprise working of plastics and be embedded in the metal insert in working of plastics, metal insert tip inside is provided with inner water-blocking groove, the joining place of inner water-blocking groove sidewall and metal insert madial wall is fillet structure, the interlude of metal insert lateral wall is provided with the anticreep wall of circular ring structure, described anticreep face of wall is circular arc camber structure, and the lateral wall of the other end relative with the end arranging inner water-blocking groove on metal insert is provided with projection.
In such scheme, described anticreep wall at least comprises one.
In such scheme, described projection comprises several, and several projections are uniformly distributed along the end lateral wall circumference of metal insert.
In such scheme, described projection comprises 6 ~ 10.
In such scheme, described metal insert is copper insert.
Compared with prior art, the beneficial effect of technical solutions of the utility model is:
(1) the utility model is designed to circular arc camber being embedded in the anticreep face of wall on the metal insert lateral wall in working of plastics, and circular arc camber effectively can increase the contact strength between working of plastics and metal insert, and contact distribution is more even.And the axial deformation relying on plastics to produce when cooling, the inside water-blocking groove in metal insert directly can infiltrate interiors of products by effectively anti-sealing, improves the preventing water leakage performance of inserts further.In addition, the utility model also stops working of plastics rotation circumferentially at the end of metal insert design projection.The structure of the utility model to metal insert is improved, and arranges anticreep wall that outer surface is circular arc camber, arranges projection and arrange inner water-blocking groove, solves bonding strength simultaneously and leaks water problem.
(2) joining place of the inner water-blocking groove sidewall of the utility model and metal insert madial wall is fillet structure, can prevent stress from concentrating, the bonding strength between further reinforced plastics part and metal insert.
