The positioning mechanisms include a first connecting cylinder 2, a second connecting cylinder 201, a plurality of moving grooves 5, a limiting rod 6, a moving block 7, an adsorption element 701, a plurality of fixing grooves 15, and an adsorption cylinder 16. The first connecting cylinder 2 is fixedly installed at one end of the pipe body 1 and at one end of the plurality of branch pipes. The second connecting cylinder 201 is located at one end of the first connecting cylinder 2. A plurality of moving grooves 5 are opened at one end of the first connecting cylinder 2. The limiting rod 6 is fixedly installed on the wall of the moving groove 5. The moving block 7 is slidably installed on the outer wall of the limiting rod 6. The adsorption element 701 is fixedly installed on one side of the moving block 7. A plurality of fixing grooves 15 are opened at one end of the second connecting cylinder 201. The adsorption cylinder 16 is fixedly installed on the wall of the fixing groove 15.

[0031] One end of the moving groove 5 extends to the position between the first card plate 3 and the first baffle 4, and the adsorption cylinder 16 is located on one side of the second card plate 13.

[0032] The adsorption element 701 adsorbs the corresponding adsorption cylinder 16.

[0033] In this embodiment, by setting a positioning mechanism, when connecting the first connecting cylinder 2 and the second connecting cylinder 201, the first spring 12 supports the moving block 7 to be positioned between the first clamping plate 3 and the first baffle 4. The adsorption member 701 and the corresponding adsorption cylinder 16 are adsorbed, and the adsorption member 701 is inserted into the corresponding adsorption cylinder 16. At this time, the positions of the first clamping plate 3 and the first baffle 4 on the first connecting cylinder 2 are aligned with the positions of the second clamping plate 13 and the second baffle 14 on the second connecting cylinder 201, which facilitates the alignment of the first connecting cylinder 2 and the second connecting cylinder 201 and allows the first connecting cylinder 2 and the second connecting cylinder 201 to be quickly inserted and engaged.

[0034] Optionally, the adsorption element 701 can be a magnet, and the adsorption cylinder 16 can be a cylindrical iron block.

[0035] In one embodiment, a plurality of first clamping plates 3 and first baffles 4 are fixedly installed on the inner wall of the first connecting cylinder 2. The first clamping plates 3 and first baffles 4 are staggered on the inner wall of the first connecting cylinder 2. A plurality of second clamping plates 13 and second baffles 14 are fixedly installed on the inner wall of the second connecting cylinder 201. The second clamping plates 13 and second baffles 14 are staggered on the inner wall of the second connecting cylinder 201, and the corresponding first clamping plates 3 and second baffles 14, and the second clamping plates 13 and first baffles 4 are engaged.

[0036] When connecting the first connecting cylinder 2 and the second connecting cylinder 201, the first clamping plate 3 is aligned with the position between the second clamping plate 13 and the second baffle 14. At this time, the second clamping plate 13 is aligned with the position between the first clamping plate 3 and the first baffle 4. Press and rotate the first connecting cylinder 2 and the second connecting cylinder 201 to make the first connecting cylinder 2 and the second connecting cylinder 201 engage.

[0037] In one embodiment, the inner wall of the movable block 7 is provided with a slot, and a ball bearing 8 is rotatably installed on the slot wall. The outer walls of the movable block 7 are provided with mounting grooves 9 on both sides. A connecting rod 10 is rotatably installed on the mounting groove 9 through a torsion spring. A roller 11 is rotatably installed on one end of the connecting rod 10.

[0038] In this example, by setting the ball bearing 8, the moving block 7 moves more smoothly on the limiting rod 6. The torsion spring supports the connecting rod 10 to rotate, so that the roller 11 is in close contact with the wall of the moving groove 5, so that the moving block 7 can maintain a certain distance from the wall of the moving groove 5 when it moves, thus limiting the movement of the moving block 7.

[0039] In one embodiment, a first spring 12 is fixedly installed at one end of the wall of the moving groove 5. The first spring 12 is installed on the outer wall of the limiting rod 6. The other end of the first spring 12 is fixedly installed on one side of the moving block 7. An installation cylinder 17 is fixedly installed on the inner wall of the first connecting cylinder 2 and the second connecting cylinder 201. A sliding groove is opened in the wall of the installation cylinder 17. A plurality of moving columns 18 are fixedly installed in the wall of the sliding groove. A moving ring 20 is slidably installed on the outer wall of the moving column 18. A plurality of installation columns 21 are fixedly installed at one end of the moving ring 20. A sealing element 22 is provided on the inner wall of the moving ring 20. An installation ring 23 is fixedly installed on the outer wall of the sealing element 22. A plurality of installation holes are opened on the installation ring 23. The installation columns 21 engage with the corresponding installation holes. A plurality of second springs 19 are fixedly installed at both ends of the wall of the sliding groove. The second springs 19 are installed on the outer wall of the corresponding moving column 18. The other end of the second springs 19 is fixedly installed at both ends of the moving ring 20.

[0040] In this example, when the first connecting cylinder 2 and the second connecting cylinder 201 are installed together, the seals 22 on the first connecting cylinder 2 and the second connecting cylinder 201 are aligned and pressed against each other, and the other end of the seal 22 is pressed against the communication point at the other end of the inner wall of the first connecting cylinder 2 and the second connecting cylinder 201, sealing the connection between the first connecting cylinder 2 and the second connecting cylinder 201. The seal 22 is inserted into the mounting post 21 on the moving post 18 through the mounting ring 23. When the first connecting cylinder 2 and the second connecting cylinder 201 are not connected, the second spring 19 supports the moving ring 20 to move upward, so that the seal 22 protrudes slightly from one end of the first connecting cylinder 2 and the second connecting cylinder 201, making it convenient to remove the seal 22 for replacement.

[0041] In one embodiment, a fixed opening is provided on the outer wall of the branch pipe, and a ball valve 24 is welded to the inner wall of the fixed opening. The inlet and outlet of the ball valve 24 at both ends correspond to the internal channel of the branch pipe, and a fire hose is provided on one side of the second connecting cylinder 201.

[0043] In this example, ball valve 24 is used to control the connection of channels in each branch pipe.
