[0042] Embodiment 4

[0043] Based on any one of Embodiments 1 - 3, as Figures 1-5As shown in the figure, an anti - detachment component is provided on the joint body 1. The anti - detachment component includes a rotating ring 11. The rotating ring 11 is rotatably arranged on the outer wall of the joint body 1. The rotating ring 11 is located on the side of the long strip sliding hole 5 away from the connecting flange 2. An annular groove 12 is provided on the side wall of the rotating ring 11. A number of contact blocks 13 are provided on the inner wall of the annular groove 12. A contact inclined surface is provided at one end of the contact block 13 close to the joint body 1.

The sliding hole 15 is arranged in the joint body 1. One end of the sliding hole 15 is internally communicated with the stepped hole 3. A baffle 16 is provided on the outer part of the sliding rod 14. A spring 17 is sleeved on the outer wall of the sliding rod 14. One end of the spring 17 is connected to the baffle 16, and the other end of the spring 17 is connected to the outer wall of the joint body 1;

[0044] A ball 18 is provided at one end of the sliding rod 14 close to the contact inclined surface. The ball 18 is in contact with the contact inclined surface;

[0045] A fixing plate 19 is provided on the outer wall of the joint body 1. A threaded hole is provided in the fixing plate 19. A screw rod 20 is arranged in the threaded hole.

Then rotate the rotating block 22. The rotating block 22 drives the screw rod 20 to rotate. The screw rod 20 drives the contact plate 21 to contact the outer wall of the rotating ring 11, so that the rotating ring 11 is fixed outside the joint body 1. Under the pressing action of the sliding rod 14, the connection between the inner wall of the hose body 4 and the outer wall of the fixed pipe 8 is tighter, further improving the stability of the connection between the hose body 4 and the joint body 1 and preventing the hose body 4 from falling off. When disassembling the hose body 4, first rotate the rotating block 22 in the reverse direction to separate the contact plate 21 from the outer wall of the rotating ring 11. Then rotate the rotating ring 11 in the reverse direction. Under the action of the spring 17, the sliding rod 14 slides into the sliding hole 15 and the sliding rod 14 is separated from the outer wall of the hose body 4. At this time, the hose body 4 can be pulled out from the joint body 1.
