[0024] See also Figure 1-4 The sealing ring B9 is slidably connected to the sealing groove 5. The sealing ring A7 and the sealing ring B9 are both made of natural rubber. The natural rubber material design of the sealing ring A7 and the sealing ring B9 improves the sealing effect of the connection between the connecting pipe A1 and the connecting pipe B2. A sleeve 10 is fixedly installed on the surface of the connecting pipe A1. The rotating block 3 and the sleeve 10 are connected by threads. The threaded connection design of the rotating block 3 and the sleeve 10 facilitates the disassembly and assembly of the connecting pipe A1 and the connecting pipe B2.

[0025] Embodiment 2

[0026] See also Figure 1-4A card slot 13 is provided at the connection between the rotating block 3 and the sleeve 10, and a sealing block 12 is provided inside the card slot 13. A sealing sleeve 11 is fixedly installed on the surface of the sealing block 12. The sealing sleeve 11 and the sealing block 12 are both made of natural rubber. The sealing block 12 is slidably connected to the card slot 13. The sliding design of the sealing block 12 and the card slot 13 makes it easy to disassemble, assemble and replace the sealing sleeve 11 and the sealing block 12.

[0027] Working principle: When assembling the connecting pipe A1 and the connecting pipe B2, first insert the sealing ring A7 and the sealing ring B9 into the placement groove A6 and the placement groove B8, and then rotate the connecting pipe B2 through the rotating block 3 to rotate the clamping block 4 until the clamping block 4 is connected to the sleeve 10 through the thread. At this time, the sealing ring B9 will be inserted into the sealing groove 5. At this time, the assembly of the connecting pipe A1 and the connecting pipe B2 can be completed. The rotating block 3, the clamping block 4, the sealing groove 5, the placement groove A6, the placement groove B8, the sealing ring A7, the sealing ring B9 and the sleeve 10 prevent rubber from being rubbed during installation. In the event of loosening of the glue, it is also convenient to disassemble and replace the sealing ring A7 and the sealing ring B9. After assembling the connecting pipe A1 and the connecting pipe B2, the sealing sleeve 11 is sleeved on the surface of the rotating block 3 and the sleeve 10. At this time, the sealing sleeve 11 will drive the sealing block 12 to be stuck in the groove 13. The sealing sleeve 11, the sealing block 12 and the groove 13 can improve the sealing effect of the connection between the rotating block 3 and the sleeve 10, and also can replace the sealing sleeve 11 and the sealing block 12 when their sealing effect is reduced due to oxidation or corrosion.
