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 water pipe joints. The existing water pipe joint mainly has two problems, namely, after the metal insert and the plastic piece are connected, the problem of water leakage at the joint occurs due to different materials;

secondly, the inserts of the water pipe joint are mostly parallel and level relative to the plastic parts, which often results in the need of installing a decorative surface outside the joint, thereby not only wasting the manufacturing cost and increasing the working procedures, but also needing secondary decoration. How to achieve good sealing effect of the water pipe joint and reduce installation procedures is the object of research by those skilled in the art.

SUMMERY OF THE UTILITY MODEL

The utility model provides a leakproofness is strong, and is difficult for corroding, and the installation is easy, does not break away from easily, the exposed water pipe head of decorative cover that the pressure resistance is strong.

In order to solve the technical problem, the utility model discloses technical scheme as follows: a water pipe joint with an exposed decorative surface comprises an insert body and a plastic pipe fitting which are connected in an injection molding mode, wherein inner threads are arranged on the inner side of the insert body, the outer end face of the insert body protrudes and is exposed relative to the plastic pipe fitting, the two ends of the insert body are respectively provided with an expanding end face, an annular groove is formed in the periphery of the insert body between the two expanding end faces, the annular grooves are arranged more than two in the axial direction of the insert body, a radial embedded groove is formed in the bottom face of a first annular groove, and an axial embedded groove is formed in the wall of a second annular groove. This kind of water pipe head exposes the relative plastics pipe fitting protrusion of outer terminal surface of inserts body and forms the decorative cover, utilizes the metal characteristic of inserts body, realizes the exposed technological effect of decorative cover, and radial embedded groove and axial embedded groove form the sealed embedding of radial and two directions of axial and mould plastics and connect, 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 body and the plastic piece, and radial looseness between the insert body and the plastic piece is prevented.

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 outer end face and the plastic pipe injection molding connecting end are provided with convex ribs, and radial looseness between the insert body and a plastic part is further prevented.

The utility model discloses an outer terminal surface bulge structure of inserts body realizes the decorative cover, avoids the secondary decoration in home decoration to can improve the radial and axial sealing performance between inserts and the injection molding, produce the state of seepage because of expend with heat and contract with cold in the liquid use when having solved the injection molding effectively and connecting the inserts.

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 joint with an exposed decorative surface comprises an insert body 1 and a plastic pipe 2 which are connected in an injection molding manner, wherein inner threads are arranged on the inner side of the insert body 1, an outer end surface 5 of the insert body 1 protrudes and exposes relative to the plastic pipe 2, two ends of the insert body 1 are respectively provided with an expanded end surface, an annular groove is arranged on the periphery of the insert body between the two expanded end surfaces, the annular grooves are axially arranged along the insert body, a radial embedded groove 10 is arranged on the groove bottom surface 12 of a first annular groove 11, and an axial embedded groove 8 is arranged on the groove wall 7 of a second annular groove 6. The radial insertion groove 10 forms a radial groove-in-groove structure on the basis of the first annular groove 11, i.e. the double-groove structure is connected with the plastic part by injection molding. The axial embedded groove 8 forms an axial in-groove structure on the basis of the second annular groove 6, namely the axial double-groove structure is connected with the plastic part in an injection molding mode. 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.
