The joint main body is made of plastic materials, the metal external thread connector pipe is combined with the planar sealing gasket, when the joint main body is connected with a water faucet, the external thread connector pipe is high in strength and is prevented from deforming, the end portion of the internal thread connector of the water faucet is matched with the planar sealing gasket to seal water leakage, a sealing strip does not need to be wound, and the joint main body is convenient to install.

Description

Pipe joint

Technical Field

The utility model relates to a hot-water heating bathroom accessory field, more specifically relate to a tap adapter.

Background

At present, in the prior art, a pipe joint includes a joint main body, an external thread mouthpiece, a pipeline and a connection cavity are arranged on the joint main body, and the joint main body is made of a plastic material or a metal material. There are problems in that: when the metal material is made, and the external thread interface is connected with the internal thread cavity of the water tap, a sealing strip needs to be wound on the external thread interface pipe, and then the external thread interface pipe is screwed to prevent water leakage; and the connection process of the connecting cavity and the plastic pipeline pre-embedded in the wall is complex. When the connector is made of plastic material, the strength of the external thread connector is low.

SUMMERY OF THE UTILITY MODEL

The utility model aims at: provides a pipe joint which has the characteristics of convenient use and high sealing property.

The utility model discloses a realize like this: a pipe joint, characterized in that: it comprises a joint main body made of plastic material, an external thread interface tube made of metal and a plane sealing gasket,

the joint main body comprises a pipeline positioned in the middle part, a hot-melting oral cavity arranged at the water outlet end and a circular cavity surrounding the water inlet end of the pipeline,

the base of the external thread mouthpiece is pre-buried in the upper end of the pipeline, and the plane sealing gasket is arranged in the circular cavity and surrounds the external thread mouthpiece.

Preferably: the circumference of the base is provided with a plurality of annular grooves, and the lower end of the base is provided with a plurality of positioning grooves.

Preferably: the inner diameter of the external thread mouthpiece is the same as the diameter of the pipeline.

Preferably: the water inlet end of the joint main body is provided with a plurality of axial arc-shaped bulges.

Preferably: the water outlet end of the joint main body is provided with a plurality of axial grooves, and one ends of the axial grooves are open.

The utility model relates to a pipe joint, the joint main part is made by plastic materials, and metal external screw thread mouth-piece combines together, reaches the sealed setting of pad in plane, and when being connected with tap, external screw thread mouth-piece intensity is big, prevent to warp, and tap's internal thread joint's tip seals up leak protection water with the sealed cooperation in plane, need not winding sealing strip, simple to operate.

Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention and are not to be construed as limiting the present invention.

As shown in fig. 1, a pipe joint comprises a joint body 1 made of a plastic material, a male nipple 2 made of metal, and a flat packing 3,

the joint main body 1 comprises a pipeline 11 positioned in the middle, a hot-melting joint cavity 12 arranged at the water outlet end and a circular cavity 13 surrounding the water inlet end of the pipeline,

the base 21 of the external thread connector pipe 2 is embedded in the upper end of the pipeline 11, and the planar sealing gasket 3 is arranged in the circular cavity 13 and surrounds the external thread connector pipe 2; when the water tap is used, the internal thread water receiving pipe of the water tap is screwed with the external thread interface pipe, and the end surface of the external thread interface pipe is tightly pressed and sealed with the plane sealing gasket 3 and extends out of the circular cavity 13. During installation, a sealing tape does not need to be wound, and the installation is convenient and quick.

The circumferential surface of the base 21 is provided with a plurality of annular grooves 211, and the lower end of the base is provided with a plurality of positioning grooves 212. With this structure, the male nipple 2 is prevented from rotating and moving in the axial direction with respect to the joint body 1.

The internal diameter of the male nipple 2 is the same as the diameter of the pipe 11.

The water inlet end of the joint main body 1 is provided with a plurality of axial arc-shaped protrusions 14. The swivel joint body 1 is convenient.

The water outlet end of the joint main body 1 is provided with a plurality of axial grooves 15, and one end of each axial groove is opened.

While embodiments of the invention have been shown and described, it will be understood by those of ordinary skill in the art that: various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
