That is, the pipe joint is kept in the blocking state before being connected with the joint connector or the joint nut, and the positioning boss 19 of the joint connector can push the closure cylinder 70 to conduct the flow passage 51 when being matched with the pipe joint, so that the practicability of the joint connector is improved.
In practical application, a fitting gap is formed between the closure cylinder 70 and the inner wall of the outer end of the outer shell 50, and the housing 10 is inserted into the fitting gap and is in threaded fit with the outer shell 50. In this embodiment, the inner wall of the outer end of the outer shell 50 is provided with an internal thread, the outer wall of the open end of the housing 10 is provided with an external thread, the closure cylinder 70 is inserted into the outer shell 50, and simultaneously, the outer shell 50 is inserted into the fit clearance, and the internal thread and the external thread are locked by rotation, thereby realizing the tight connection between the joint connector and the joint.
The above is only the optional embodiment of the present invention, and not the scope of the present invention is limited thereby, all the equivalent structure changes made by the contents of the specification and the drawings are utilized under the inventive concept of the present invention, or the direct/indirect application in other related technical fields is included in the patent protection scope of the present invention.
