Therefore, the pressure pipe nut is also shown in the figure to facilitate the stable connection of the pipeline seal.

The improvement of the present invention is that: on the joint main body 1, a radial slot 11 and a pin hole 12 are formed on the end face of the movable joint 3, and the pin hole 12 is located in one of the axial insertion holes 10. side, a "T" shaped bayonet 121 and bayonet spring 122 are installed in it; a bayonet steel sheet 5 is installed inside the radial bayonet groove 11, and the bayonet steel sheet 5 is provided with a socket for the movable joint 3 The through hole 51 through which the insertion portion 31 passes is slightly larger than the axial insertion portion 31; on one side of the through hole 51 there is a section extending along the direction of the radial slot 11 for the T-shaped card. The chute 511 where the pin 121 slides, and the clamping steel sheet 5 also has a pushing part 52 located in the lateral direction of the joint body 1, and a steel leaf spring 53 is provided between the pushing part 52 and the side wall of the joint body 1;

The root of the insertion portion 31 of the movable joint 3 forms a groove 311 whose height is equivalent to the thickness of the locking steel sheet 5, that is, the insertion portion 31 passes through the opening of the locking steel sheet 5. Behind the hole 51, the edge of the through hole 51 of the clamping steel sheet 5 snaps into the groove 311, thereby preventing the insertion part 31, that is, the movable joint 3 from detaching in reverse, and completing the insertion of the movable joint 3 and the joint main body 1, that is, Complete the access connection.
