Description

Water pipe joint insert with internal thread

Technical Field

The utility model relates to an inserts especially indicates to relate to a water pipe head inserts with internal thread.

Background

In daily life and industrial production, water or other liquid is generally conveyed by using pipelines, and adjacent pipelines are connected or the pipelines are connected with a valve body, a faucet and the like by using pipeline joints. At present, a large number of plastic pipe joints are used as connecting parts, and the plastic pipe joints are generally manufactured by injection molding and fusion of plastic and metal inserts to form two structures of inserts and plastic parts. The existing insert structure mostly adopts the structure of a connecting groove to be welded with a plastic pipe fitting, the water leakage problem caused by the gap between the insert and the plastic part often appears along with the temperature change in the using process, and the problem of how to avoid the water leakage between the insert and the plastic part is the object of the research of technical personnel in the field.

SUMMERY OF THE UTILITY MODEL

The utility model provides a terminal surface can play the decorative effect, is difficult for a water pipe head inserts with internal screw thread that leaks between inserts and the injection molding.

In order to solve the technical problem, the utility model discloses technical scheme as follows: the utility model provides a water pipe head inserts with internal thread, including the inserts body, inserts body inboard is equipped with the internal thread, and the inserts body outside is equipped with the annular groove, the annular groove arrange more than two along inserts body axial, wherein be equipped with radial embedded groove on the tank bottom face of first annular groove, wherein be equipped with the axial embedded groove on the cell wall of second annular groove. This kind of a plurality of annular groove structure cooperation radial embedded groove and axial embedded groove form the sealed embedding of radial and two axial directions and mould plastics and be connected, prevent that water pipe head inserts and working of plastics from appearing the problem of leaking in the use.

The insert body is characterized in that one axial end of the insert body is an outer end face, the other end of the insert body is a limiting end formed by more than two bulges in an arranged mode, radial limiting is carried out between the insert and the plastic piece, and radial looseness between the insert and the plastic piece is prevented.

The inner side surface of the outer end surface is provided with an occlusion groove, the occlusion groove structure generates axial occlusion force after injection molding and filling, and the injection molding material in the annular groove and the annular groove is axially stretched to prevent the insert and the plastic part from being axially loosened.

The inner side of the limiting end is provided with a reducing ring. One side of the reducing ring is in contact with the internal thread on the inner side of the insert body, and the other side of the reducing ring is a horizontal end face which forms a 90-degree included angle with the inner pipe wall of the insert body. The reducing ring structure and the side surface connected with the internal thread are used as the limiting end surface of the internal thread, and the other side is used as the injection molding limiting surface between the insert body and the plastic part, so that the technical purpose of single-ring double limiting is achieved.

The utility model discloses a sealed embedding of a plurality of annular groove structure cooperation radial embedded groove and axial embedded groove formation radial and two directions of axial is moulded plastics and is connected, prevents that water pipe head inserts and working of plastics problem of leaking from appearing in the use.

Detailed description of the preferred embodiments

The technical solution of the present patent will be described in further detail with reference to the following embodiments.

Referring to fig. 1-4, a water pipe connector insert with internal threads includes an insert body 1, the internal threads are disposed on the inner side of the insert body 1, the outer side of the insert body 1 is provided with two or more annular grooves axially arranged along the insert body, wherein a radial embedded groove 3 is disposed on a groove bottom surface 15 of a first annular groove 4, and an axial embedded groove 18 is disposed on a groove wall 16 of a second annular groove 2. The radial embedded groove 3 forms a radial in-groove structure on the basis of the first annular groove 4, namely, the double-groove structure is connected with a plastic piece in an injection molding mode. The axial insertion groove 18 forms an axial in-groove structure on the basis of the second annular groove 2, i.e. an axial double-groove structure is connected with the plastic part by injection molding. The groove inside groove structure of two kinds of directions has realized the three-dimensional sealed effect between inserts and the injection molding like this, prevents to appear the problem of leaking.

Preferably, the insert body 1 has an outer end face 12 at one axial end and a limiting end at the other axial end, wherein the limiting end is formed by arranging more than two protrusions 5. The technical effect of directly being used for decoration is achieved by exposing the outer end faces 12 and utilizing the metal material characteristic of the insert body 1, and the protrusions 5 are radially limited to prevent radial displacement between the insert body and an injection molding piece.

In order to further improve the axial meshing capability of the insert, the inner side surface of the outer end surface 12 is provided with a meshing groove 8 for injection molding and meshing the plastic pipe fitting.

Preferably, the inner side of the limiting end is provided with a reducing ring 6. One side of the reducing ring 6 is contacted with the internal thread on the inner side of the insert body 1, the other side of the reducing ring is a horizontal end face which forms an included angle of 90 degrees with the inner pipe wall of the insert body 1, and double-side limiting performance is formed on two sides of the reducing ring 6.

The utility model discloses an its connection plastics pipe fitting of moulding plastics of water pipe head inserts, and the face of moulding plastics between the plastics pipe fitting have included that interlock groove 8, first annular groove 4, second annular groove 2, radial embedded groove 3, axial embedded groove 18, protruding 5 arrange the multiaspect of a plurality of different positions such as spacing end that constitute, different angles mould plastics connection structure, play good sealing performance.

Although the preferred embodiments of the present patent have been described in detail, the present patent is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present patent within the knowledge of those skilled in the art.
