Technical Field

The utility model relates to the technical field of water heating, in particular to a highly sealed internal and external thread plug.

Background Art

Plugs are commonly used pipe fittings in the installation of plumbing systems, and their main function is to seal. However, the plugs currently used in the plumbing market are single-use plugs made of stainless steel or metal, which can only block internal or external threads. You need to determine the number of internal and external threads when purchasing, and you can only install them accordingly during installation. At the same time, you need to wrap the raw tape around it to ensure the sealing. For some novices, it is easy to make mistakes in the winding direction and number of turns of the raw tape, resulting in water leakage.

Utility Model Content

In order to solve the above defects, the utility model provides a high-sealing internal and external thread plug, which solves the problem that the current plugs are all single-use plugs, causing inconvenience in installation and saving the step of winding raw tape.

In order to achieve the above-mentioned purpose, the technical solution provided by the utility model is: a highly sealed internal and external thread plug, comprising an internal thread joint, a blocking block and an external thread joint that are integrally formed and connected in sequence, the blocking block is provided with a first annular sealing groove on a side facing the internal thread joint, and the inner diameter of the first annular sealing groove is smaller than the inner diameter of the internal thread joint; the blocking block is provided with a second annular sealing groove around the external thread joint on a side facing the external thread joint, and the inner diameter of the second annular sealing groove is larger than the outer diameter of the external thread joint.

Furthermore, the outer wall of the internal thread connector is hexagonal, and internal threads are evenly arranged on the inner wall.

Furthermore, external threads are evenly and circumferentially arranged on the outer side wall of the external thread connector.

Furthermore, an inner through hole is axially penetrated inside the outer thread connector, and the inner through hole is closed by the blocking block.

Furthermore, the inner thread connector, the blocking block and the outer thread connector are integrally formed by injection molding, and the material is one of PP, PPR, PE or ABS.

Furthermore, sealing gaskets are respectively disposed in the first annular sealing groove and the second annular sealing groove.

Compared with the prior art, the utility model has the following beneficial effects:

1. By setting up the coordinated use of the internal thread joint, the plug and the external thread joint, the internal thread on the internal thread joint and the external thread on the external thread joint can be used to achieve threaded connection with the internal thread or external thread pipe, which is convenient for sealing the end of the pipe and solves the problem that the single plug cannot be used universally. The outer wall of the internal thread joint is set to a hexagonal shape, and the plug can be tightened with a hexagonal wrench to facilitate construction.

2. By setting the first annular sealing groove and the second annular sealing groove inside and using them in conjunction with the sealing gasket, after tightening, the sealing gasket is sealed and abutted against the end of the pipe, which can achieve the effect of improving the pipe sealing. At the same time, it can save the winding steps of the raw tape and achieve the effect of quick installation.

DETAILED DESCRIPTION

In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

As shown in Figures 1 to 5, a highly sealed internal and external thread plug includes an internal thread joint 1, a blocking block 2 and an external thread joint 3 which are integrally formed and connected in sequence, wherein the blocking block 2 is provided with a first annular sealing groove 4 on a side facing the internal thread joint 1, and the inner diameter of the first annular sealing groove 4 is smaller than the inner diameter of the internal thread joint 1; the blocking block 2 is provided with a second annular sealing groove 5 around the external thread joint 3 on a side facing the external thread joint 3, and the inner diameter of the second annular sealing groove 5 is larger than the outer diameter of the external thread joint 3.

By adopting the above scheme, by setting the coordinated use of the internal thread joint 1, the blocking block 2 and the external thread joint 3, the internal thread joint 1 can be used to connect with the internal thread at the end of the pipeline, and the external thread joint 3 can be used to connect with the external thread at the end of the pipeline, thereby realizing the blocking effect of two joints with one plug, solving the problem that a single plug cannot be used universally. When necessary, the blocking block 2 can also be opened to realize the connection of the pipelines between the internal thread joint 1 and the external thread joint 3, thereby playing the role of converting the internal thread and external thread of the pipeline joint.

As shown in FIG. 1 , FIG. 2 , and FIG. 3 , the outer wall of the female thread connector 1 is hexagonal, and the inner wall is evenly surrounded by female threads 11 ;

By adopting the above scheme, the internal thread can be provided to achieve threaded connection with the pipeline to ensure the sealing of the connection. The joint is provided in a hexagonal shape and can be installed with a wrench.

External threads 31 are evenly and circumferentially arranged on the outer wall of the external thread connector 3 .

By adopting the above solution, by providing an external thread, a threaded connection can be made with the pipeline to ensure the sealing of the connection.

As shown in FIG. 3 and FIG. 5 , an inner through hole 6 is axially penetrated inside the outer thread connector 3 , and the inner through hole 6 is closed by the blocking block 2 .

By adopting the above solution, the inner through hole 6 and the blocking block 2 are provided to achieve the effect of sealing the pipeline by the outer thread joint 3.

As shown in FIG. 1 to FIG. 5 , the inner thread connector 1 , the blocking block 2 and the outer thread connector 3 are integrally formed by injection molding, and the material is one of PP, PPR, PE or ABS.

By adopting the above solution, the material of the inner thread connector 1, the block 2 and the outer thread connector 3 is set to be one of PP, PPR, PE or ABS and is integrally injection molded, which can save production costs while ensuring quality.

As shown in FIG. 5 , sealing gaskets 7 are respectively disposed in the first annular sealing groove 4 and the second annular sealing groove 5 .
