The rotating shaft 20 is rotatably embedded in the top of the outer wall of the mounting frame 16.

[0052] In this embodiment, the mounting frame 16 is used to mount and place the annular plate 17 , and the second gear 19 is driven to rotate by the rotating shaft 20 , which can drive the first gear 18 to drive the annular plate 17 to rotate.

[0053] Specifically, each group of extrusion components includes an extrusion member 21, a moving member 22, a guide hole 23 and a cam hole 24. The extrusion member 21 slides through the outer wall of the male connector 3, the moving member 22 is fixedly arranged at the top of the outer wall of the extrusion member 21, the guide hole 23 is opened at the top of the outer wall of the mounting frame 16, the moving member 22 is slidably embedded in the inner wall of the guide hole 23, the cam hole 24 is opened at the top of the outer wall of the annular plate 17, and the moving member 22 is slidably embedded in the inner wall of the cam hole 24.

[0054] In this embodiment: as the annular plate 17 rotates, the position of each cam hole 24 can be changed, so that the cam hole 24 pushes the top of the movable member 22 to move, and the guide hole 23 limits the moving direction of the movable member 22, so that the movable member 22 drives the extrusion member 21 to move in the guide hole 23, so that each extrusion member 21 synchronously squeezes the inner wall of the sealing ring 7, so that the sealing ring 7 is close to the inner wall of the female connector 1, thereby improving the sealing effect.

[0055] Specifically, the rotating assembly includes a rotating shaft 25, a first bevel gear 26, a second bevel gear 27 and a rotating plate 28. The rotating shaft 25 is rotatably embedded in one side of the outer wall of the male joint 3, the first bevel gear 26 is fixedly sleeved on the outer wall of the rotating shaft 25, the second bevel gear 27 is fixedly sleeved on the outer wall of the rotating shaft 20, and the second bevel gear 27 is meshed with the first bevel gear 26, and the rotating plate 28 is fixedly set on one side of the outer wall of the rotating shaft 25.

[0056] In this embodiment, the rotating plate 28 is manually driven to rotate, so that the rotating shaft 25 drives the first bevel gear 26 to rotate, and the second bevel gear 27 drives the rotating shaft 20 to rotate, which is used to drive the second gear 19 to rotate.

[0057] Specifically, the elastic component includes a fixed frame 29, a fixed rod 30, a second spring 31 and a fixed hole 32. The fixed frame 29 is fixedly embedded in one side of the outer wall of the rotating plate 28, and the fixed rod 30 slides through both sides of the outer wall of the fixed frame 29. The second spring 31 is fixed between the fixed frame 29 and the fixed rod 30. The fixing hole 32 is opened on one side of the outer wall of the lock core rod 11, and the fixed rod 30 is slidably embedded in the inner wall of the fixing hole 32.

[0058] In the present embodiment: through the action of the second spring 31, the fixing rod 30 in the fixing frame 29 can enter the fixing hole 32, and the position of the rotating plate 28 and the lock core rod 11 can be limited and fixed, thereby preventing the rotating plate 28 from rotating at will, and further limiting the movement of the lock core rod 11, thereby effectively improving the stability of the connection between the female connector 1 and the male connector 3, and preventing the male connector 3 from rotating on the inner wall of the female connector 1, thereby reducing the wear of the sealing ring 7 and extending the service life of the sealing ring 7.

[0059] Specifically, the rotating shaft 20 movably passes through the bottom of the inner wall of the first cavity 14 , and the second bevel gear 27 is located inside the first cavity 14 .

[0060] In this embodiment, the second gear 19 is driven to rotate by the rotating shaft 20 .

[0061] When in use, the female connector 1 is inserted into the male connector 3, and the limit block 6 is inserted along the gap of the limit plate 5, which can effectively prevent the male connector 3 from being separated from the female connector 1, and the positioning block 9 is just inserted into the starting section of the positioning groove 8, and the male connector 3 is rotated to the right until the positioning block 9 is stuck and does not move. At this time, the limit block 6 is just located below the limit plate 5, so that the limit plate 5 is stuck with the limit block 6, and the male connector 3 and the female connector 1 are initially connected. At the same time, the lock core rod 11 is just aligned with the lock hole 10, and the lock core rod 11 is stuck in the lock hole 10 under the action of the first spring 13 and locked, fixing the connection between the male connector 3 and the female connector 1 to prevent the male connector 3 and the female connector 1 from rotating. Then, the rotating plate 28 is manually driven to rotate, so that the rotating shaft 25 drives the first bevel gear 26 to rotate, drives the second bevel gear 27 to drive the rotating shaft 20 and the second gear 19 to rotate, and drives the first gear 18 to drive the annular plate 17 to rotate, which can change each The position of each cam hole 24 makes the cam hole 24 push the top of the moving part 22 to move, and the guide hole 23 limits the moving direction of the moving part 22, so that the moving part 22 drives the extruding part 21 to move in the guide hole 23, so that each extruding part 21 synchronously squeezes the inner wall of the sealing ring 7, so that the sealing ring 7 is close to the inner wall of the female connector 1, and the sealing effect is improved. The fixed frame 29 on the rotating plate 28 is located on one side of the lock core rod 11. Under the action of the second spring 31, the fixed rod 30 in the fixed frame 29 can enter the fixed hole 32, and the position of the rotating plate 28 and the lock core rod 11 can be limited and fixed to prevent the rotating plate 28 from rotating at will, further restricting the movement of the lock core rod 11, thereby effectively improving the stability of the connection between the female connector 1 and the male connector 3, and preventing the male connector 3 from rotating on the inner wall of the female connector 1, thereby reducing the wear of the sealing ring 7 and extending the service life of the sealing ring 7.

[0062] Under the pressurized state, due to the effect of the seal 9 and the locking of the limit block 10 by the limit plate 3, the male connector can be effectively prevented from rushing out of the liquid passage hole of the female connector 1.
