Description

Technical Field

[0001] The utility model relates to the technical field of pipe joints, in particular to a double-thread pipe joint assembly. Background Technique

[0002] At present, one end of a commonly used pipe joint is provided with an external thread and the other end is provided with an internal thread. Therefore, these threads are an important part of the joint. However, when the threads at both ends of the existing double-thread pipe joint are not in use, no corresponding protection device is provided, and they are easily damaged under the action of external forces, resulting in the scrapping of the joint and inability to be used, greatly reducing the practicability.

[0003] For example, the publication number is CN215111086U, a double-thread pipe joint, which includes a joint body, an end cover assembly and a sealing and protection assembly. The joint body includes a first connector, a mounting nut and a second connector. The mounting nut is fixedly connected between the first connector and the second connector. The end cover assembly includes an end cover body, and the end cover body is screwed to one end of the first connector away from the mounting nut. The sealing and protection assembly includes a protective ring sleeve and a sealing ring.

[0004] The above application effectively protects the external thread by blocking the end of the first connector with the end cover body, and effectively protects the first internal thread with the sealing cover, effectively preventing the joint body from being damaged under the action of external forces when not in use, greatly improving the practicability. However, when the double-thread components are connected, glue is used for connection, and the rotational force between the two components is completely limited by the adhesion performance and friction force of the glue. When the torque is too large, the two will still rotate relative to each other, and it is not reliable to use. Therefore, there is an urgent need in the market to develop a double-thread pipe joint assembly to help people solve the existing problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a double-thread pipe joint assembly to solve the problem that when the general double-thread components are connected by glue, the rotational force between the two components is completely limited by the adhesion performance and friction force of the glue, and when the torque is too large, the two will still rotate relative to each other, and it is not reliable to use as mentioned in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A double-thread pipe joint assembly, including a double-thread pipe joint assembly. The double-thread pipe joint assembly includes a first component and a second component. The first component includes a connecting cylinder, and an inlay groove is arranged inside the connecting cylinder. The second component includes an insertion pipe, and a limiting block is arranged on the outer side of the insertion pipe. The limiting block is engaged with the inlay groove, and both the limiting block and the inlay groove are provided with two.

[0007] Through the above technical solution, two inlay grooves are provided inside the connecting cylinder of the first component, and at the same time, two limiting blocks are provided outside the insertion pipe of the second component. The size of the limiting block fits the size of the inlay groove. When connecting the first component and the second component, the insertion pipe is directly inserted into the connecting cylinder, and the limiting block is inserted into the inlay groove to limit and fix the first component and the second component, so that they cannot rotate relative to each other, improving the reliability of use.

[0008] In a preferred embodiment of the present invention, it can be further configured that: a glue blocking groove is provided inside the connecting cylinder, a first octagonal nut is provided below the connecting cylinder, a connecting head is provided below the first octagonal nut, a second internal thread groove is provided inside the connecting head, and a water outlet is provided inside the first octagonal nut.

[0009] Through the above technical solution, when the first component and the second component are connected, glue can be prevented from flowing into the water outlet, thereby avoiding blockage inside the component and preventing the situation where water cannot be sprayed during a fire, improving the safety of use.

[0010] In a preferred embodiment of the present invention, it can be further configured that: a second octagonal nut is provided above the insertion pipe, and a first internal thread groove is provided inside the second octagonal nut.
