Abstract

The utility model relates to a high-seal high-strength copper insert which comprises an inner threaded insert body and an outer threaded insert body. The copper insert is made of H59-1 copper materials, the copper insert is provided with three grooves which comprise two dovetail grooves and one flat groove, the flat groove is located on one side of the two dovetail grooves, the two dovetail grooves and thermoplastic plastics are embedded together, a rubber sealing ring is added on the flat groove, and the two dovetail grooves, the flat groove and the thermoplastic plastics are formed through one-time injection moulding. The high-seal high strength copper insert has the advantages that the copper insert formed by the technical scheme increases stress cracking resistant performance and long-term hydrostatic strength capability, and completely overcomes the weaknesses that when mechanical connection is adopted, and pipe fitting bodies leak water easily, are frozen and crack easily in winter and has smell due to the fact that the pipe fitting bodies generate chemical decomposition under heating.

Description

A kind of high sealing high-strength copper inserts

Technical field

The utility model relates to the plastic pipe field, a kind of high sealing high-strength copper inserts that is mainly used in the thermoplastic single injection-molded.

Background technique

At present, in the plastic pipe industry, pipe fitting comprises multiple product with copper insert, and because copper insert structural type and quality of materials different tend to cause the generation of copper insert part water leakage phenomenon, affects the use condition of whole piece pipe-line system.

Summary of the invention

The purpose of this utility model is to overcome the deficiency that prior art exists, and provides a kind of for preventing that thermoplastic and copper insert can not well be integrated, and causes the high sealing high-strength copper inserts of the generation of water leakage phenomenon.

The purpose of this utility model is finished by following technical solution, and it comprises inner screw thread insert, external screw thread insert, and this copper insert adopts the manufacturing of H59-1 copper material to form, and copper insert is provided with three road grooves, i.e. twice dovetail groove and one flat grooves; This flat grooves is positioned at a side of twice dovetail groove.

As preferably, described twice dovetail groove and thermoplastics inserts are together; Be added with rubber seal on the flat grooves, this twice dovetail groove, flat grooves and thermoplastic pass through single injection-molded.

The beneficial effects of the utility model are: the copper insert of finishing by technique scheme, anti-stress cracking performance and long-term hydrostatic strength ability strengthen, and overcome fully that mechanical connection, pipe fitting body easily leak, easy bursting by freezing in winter, have met heat and produce the weakness that chemolysis has peculiar smell.

Embodiment

Below in conjunction with accompanying drawing the utility model is done detailed introduction: shown in accompanying

drawing

1,2,3,4, the utility model comprises inner screw thread insert 1, external screw thread insert 2, this copper insert adopts the manufacturing of H59-1 copper material to form, and copper insert is provided with three road grooves, i.e. twice dovetail groove 3 and one flat grooves 4; This flat grooves 4 is positioned at a side of twice dovetail groove 3.Described twice dovetail groove 3 is embedded in thermoplastic 5; Be added with rubber seal 6 on the flat grooves 4, this twice dovetail groove 3, flat grooves 4 are passed through single injection-molded with thermoplastic 5, and copper insert and thermoplastic are integrated.

The utility model is not limited to above-mentioned mode of execution; no matter do any variation in its shape or material formation; every employing structural design provided by the utility model all is a kind of distortion of the present utility model, all should think within the utility model protection domain.
