Two pipes 8 can be inserted from both ends of the joint body 1 until the end of the pipe 8 abuts the end of the limiting rib 11. At this time, the sealing ring 4 abuts the annular side of the pipe 8. By setting a plurality of limiting ribs 11, the pipe 8 can be installed and limited. By setting the sealing ring 4, the sealing effect can be improved to prevent the pipe 8 from leaking when liquid or gas passes through. In the present invention, two sealing rings 4 are provided in each first annular groove 12, and the two sealing rings 4 can further improve the sealing effect.

[0037] An annular platform 13 is provided at both ends of the joint body 1. The annular platform 13 is integrally formed with the joint body 1. The outer diameter of the annular platform 13 is smaller than the outer diameter of the joint body 1. A rotating sleeve 3 is sleeved on the outside of the annular platform 13. Specifically, a limiting sleeve 2 is provided at both ends of the annular platform 13. The limiting sleeve 2 includes a first annular rib 21. The first annular rib 21 is sleeved on the outside of the annular platform 13. The rotating sleeve 3 is positioned in a groove formed by the end of the first annular rib 21 and the end of the joint body 1. The limiting sleeve 2 includes a second annular rib 22. The second annular rib 22 is inserted into the annular platform 13 and is threadedly connected to the annular platform 13. The second annular rib 22 is sleeved on the outside of the pipe 8 and is clearance-matched with the outer wall of the pipe 8.

[0038] The limiting sleeve 2 is connected to the annular platform 13 by a threaded connection, which is convenient for the disassembly and assembly of the limiting sleeve 2. By setting the first annular rib 21, not only can the rotating sleeve 3 be limited to prevent the rotating sleeve 3 from separating from the annular platform 13, but also the assembly process can be optimized to facilitate the disassembly and assembly of the rotating sleeve 3. By setting the second annular rib 22, the pipe 8 can be limited to reduce the shaking amplitude of the pipe 8, which is beneficial to improve the sealing effect and the fixing effect of the pipe 8.

[0039] A second annular groove 15 is provided on the inner wall of the annular platform 13, and an arc-shaped fastening sleeve 5 is provided in the second annular groove 15. A stopper 16 is provided in the second annular groove 15, and the stopper 16 is located between the two ends of the arc-shaped fastening sleeve 5. The arc-shaped fastening sleeve 5 is a metal part, and the material is consistent with the material of the retaining spring. By providing the stopper 16, the arc-shaped fastening sleeve 5 can be limited to prevent the arc-shaped fastening sleeve 5 from rotating in the second annular groove 15.

[0040] The outer wall of the annular platform 13 is provided with a plurality of limiting grooves 14, and a slider 6 is provided in the limiting groove 14. One end of the slider 6 passes through the annular platform 13 and abuts the outer wall of the arc-shaped fastening sleeve 5. Rotating the rotating sleeve 3 can drive the slider 6 to move toward the inside of the joint body 1 so that the inner wall of the arc-shaped fastening sleeve 5 exceeds the inner surface of the joint body 1. In the present invention, the outer wall of each annular platform 13 is provided with three limiting grooves 14 evenly distributed along the axis of the joint body 1. The slider 6 can move in the limiting groove 14. When the slider 6 moves toward the pipe 8, it can push the arc-shaped fastening sleeve 5 to move and abut the pipe 8. The arc-shaped fastening sleeve 5 can clamp the pipe 8, thereby preventing the pipe 8 from loosening. Through the above-mentioned operation method, the pipe 8 can be clamped and fixed directly by manual means without the aid of any tools, which greatly facilitates the fixing operation of the pipe 8. Moreover, when the pipe 8 needs to be disassembled, it is only necessary to manually rotate the rotating sleeve 3 to complete the disassembly of the pipe 8, which is convenient and quick to operate.

[0041] Specifically, the rotating sleeve 3 includes a through hole 31 corresponding to the slider 6, and the outer end surface of the slider 6 can be inserted into the through hole 31 or abut the annular inner wall of the rotating sleeve 3. The contour of the outer end surface of the slider 6 in the horizontal direction is arc-shaped, and the inner end surface of the slider 6 is provided with a thimble 61 and a limit platform 62. The thimble 61 passes through the annular platform 13 and abuts the outer wall of the arc-shaped fastening sleeve 5. A spring 7 is provided on the outer side of the thimble 61, and the two ends of the spring 7 respectively abut the limiting groove 14 towards one side of the arc-shaped fastening sleeve 5 and the inner end surface of the slider 6. The limit platform 62 can abut or disengage from the annular inner wall of the rotating sleeve 3. When the outer end surface of the slider 6 is located in the through hole 31, the arc-shaped fastening sleeve 5 does not contact the pipe 8. Through the cooperation between the arc-shaped outer end surface of the slider 6 and the annular inner wall of the rotating sleeve 3, when the rotating sleeve 3 is rotated When the pipe 8 needs to be removed, the inner wall of the rotating sleeve 3 can squeeze the outer end surface of the slider 6, so that the slider 6 moves toward the pipe 8. When the outer end surface of the slider 6 completely abuts the inner wall of the rotating sleeve 3, the slider 6 can produce the maximum displacement. At this time, the arc-shaped fastening sleeve 5 can firmly abut the outer wall of the pipe 8, thereby fixing the pipe 8 to prevent the pipe 8 from being separated from the joint body 1, and the slider 6 and the through hole 31 are in a misaligned state; when the pipe 8 needs to be removed, it is only necessary to rotate the rotating sleeve 3 until the slider 6 is facing the through hole 31. The slider 6 is quickly reset by the action of the spring 7 and the arc-shaped fastening sleeve 5, so that the outer end surface of the slider 6 is inserted into the through hole 31, and the arc-shaped fastening sleeve 5 is separated from the pipe 8, and the pipe 8 can be pulled out. Through the above design, not only the installation and fixation of the pipe 8 is greatly facilitated, but also the operation is convenient, fast and efficient.

[0042] When the pipe 8 is fixed, the slider 6 is misaligned with the through hole 31, which can effectively prevent the slider 6 from rebounding, greatly improving the reliability of the connection of the pipe 8. Through the above design, the mechanism for fixing the pipe 8 (rotating sleeve 3, arc-shaped fastening sleeve 5 and slider 6) can be directly assembled on the joint body 1, which can prevent the loss of the fixing mechanism and further improve the fixing efficiency of the pipe 8.

[0043] The outer ring of the rotating sleeve 3 is provided with an anti-slip portion 32 , which can be protrusions or grooves arranged at intervals. By providing the anti-slip portion 32 , the friction force can be increased when the rotating sleeve 3 is rotated, thereby facilitating the rotation of the rotating sleeve 3 .
