Summary of the invention
It is straight-through that the technical issues that need to address of the present invention have provided a kind of thermoplasticity with metal external thread joint, is intended to solve the above problems.
In order to solve the problems of the technologies described above, the present invention realizes through following technological scheme:
The present invention includes: injection moulding fuse about two bellmouths: one of them is injection molded by metal external thread joint and thermoplastic resin structure layer; The thermoplastic resin structure layer is coated on the root outer ring of metal external thread joint; The root inner ring of thermoplastic resin structure layer is provided with ring cross-section, and ring cross-section links to each other with the root of metal external thread joint; Wherein another is made up of inside and outside double-layer structure; The external structure layer is injection molded by thermoplastic resin, and its inboard has and is no less than 2 grooves, and the oral area of groove is equal with the oral area of external structure layer, and the root of groove is equal with ring cross-section; The circular row pore that penetrates the external structure layer is arranged in every groove; The inner structure layer is injection molded by metal hollow light wall pipe and thermoplastic resin, and thermoplastic resin is coated on the outer ring of metal hollow light wall pipe, and metal hollow light wall pipe oral area is equal with inner structure layer oral area, and metal hollow light wall pipe root is equal with ring cross-section.
Compared with prior art, the invention has the beneficial effects as follows: both guaranteed this straight-through inner latus rectum, improved welding speed and welding quality again.
