[0002] Pipe connectors are essential pipe parts in pipe connection. According to the usage method, they can be divided into external thread end-connected pipe connectors, ferrule pipe connectors, and self-fixing pipe connectors. Currently, the most commonly used is the external thread end-connected pipe connector. After retrieval, it is found that in the prior art with the publication number: CN218599049U, there is a knurled threaded quick connector. This connector includes a clamping pipe. One end of the clamping pipe is integrally connected with a clamping package. The clamping package is circular. There is an annular groove on the inner side surface of the clamping package. Sealing rings are arranged on the front side wall and the rear side wall of the groove. The other end of the clamping package is connected with a connecting pipe. A hexagonal flange is connected to the connecting pipe. The hexagonal flange is hollow inside. The hexagonal flange is connected with an external threaded pipe. The connecting pipe and the external threaded pipe are both communicated with the hexagonal flange. A number of concave points are distributed on each tooth of the external threaded pipe. The beneficial effect of this patent is that knurling is applied to the external threaded pipe, and when winding the sealing strip, the pressure between the sealing strip and the thread is dispersed, preventing the sealing strip from being squeezed to death with the thread and causing the thread to derail. A clamping package is provided. During installation, the clamping pipe and the connected pipe are directly clamped with a hydraulic fixture, which is convenient, fast, and has high installation efficiency.

[0003] To sum up: In the above case, it has no structure to prevent the reverse rotation of the pipe caused by external force, resulting in the easy reverse rotation and loosening of the threaded connection of the external threaded pipe, thereby reducing the sealing performance and stability of the connection.
