However, when the internal thread joint of the fire-fighting pipeline is connected to other components, glue is generally used for connection, and the component is embedded inside the internal thread joint. However, the glue is easily squeezed and overflowed to the bottom, and then enters the pipeline to block the water outlet, resulting in no water spraying during a fire and affecting the use safety. Therefore, there is an urgent need in the market to develop an internal thread joint to help people solve the existing problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide an internal thread joint to solve the problem that when the internal thread joint of the fire-fighting pipeline is connected to other components, glue is generally used for connection, the component is embedded inside the internal thread joint, but the glue is easily squeezed and overflowed to the bottom, and then enters the pipeline to block the water outlet, resulting in no water spraying during a fire and affecting the use safety as mentioned in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical scheme: an internal thread joint, including an internal thread joint, the internal thread joint includes a connecting pipe, an embedding hole is arranged inside the connecting pipe, the inner wall of the embedding hole is an adhesive wall, and a glue blocking ring is arranged at the bottom of the embedding hole.

[0007] Through the above technical scheme, at the bottom of the embedding hole, a glue blocking ring protrudes inside the joint. When the component is connected to the internal thread joint, it can prevent the glue from flowing into the nozzle, thus avoiding blockage of the nozzle, no water spraying during a fire, and improving the use safety.

[0008] The utility model can be further configured in a preferred example as follows: two positioning chutes are arranged inside the embedding hole.

[0009] Through the above technical solution, by setting the positioning chute, on the one hand, the installation accuracy can be improved, and on the other hand, the rotation between the component and the internal thread joint can be prevented, further improving the use reliability.

[0010] In a preferred example of the present utility model, it can be further configured that: an octagonal nut is arranged below the connecting pipe, and a connector is arranged below the octagonal nut.

[0011] In a preferred example of the present utility model, it can be further configured that: an internal thread groove is arranged inside the connector.

[0012] In a preferred example of the present utility model, it can be further configured that: a water outlet is arranged inside the octagonal nut.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] 1. At the bottom of the inlay hole of this utility model, a glue-blocking ring protrudes inside the joint. When the component is connected to the internal thread joint, it can prevent glue from flowing into the nozzle, thus avoiding nozzle blockage and the inability to spray water in case of a fire, improving the use safety.

[0015] 2. Through the setting of the positioning chute of this utility model, on the one hand, the installation accuracy can be improved, and on the other hand, the rotation between the component and the internal thread joint can be prevented, further improving the use reliability.
