[0007] Preferably, a positioning plate is fixedly provided on the rotating ring, a screw is screwed on the positioning plate, and one end of the screw is tightly pressed against the outer surface of the pipe.

[0008] Preferably, a sealing gasket is fixedly arranged in the slot.

[0009] Preferably, the end of the insertion rod and the port of the insertion hole are both chamfered.

[0010] Beneficial Effects

[0011] The utility model provides a mine ventilation duct docking device, which has the following beneficial effects: by rotating the swivel, multiple insertion rods on the first connecting rod can be simultaneously inserted into the insertion holes in the second connecting rod or removed from the insertion holes in the second connecting rod, thereby realizing the rapid connection of the first connecting rod and the second connecting rod, and the swivel can be prevented from rotating by tightening the screws, thereby further improving the stability of the connection.
