[0035] The working principle of this utility model:

[0036] When in use, the pipe 5 is assembled with the joint 4, and then the rubber ring 18 is sleeved on the surface of the pipe 5. At this time, the plug ring 7 and the fixed ring 6 can be assembled. During assembly, the rotating column 1305 is rotated clockwise, and the rotating column 1305 drives the main gear 1303 to rotate clockwise, and the main gear 1303 drives the meshing driven gear 1304 to rotate counterclockwise. At this time, the main gear 1303 and the driven gear 1304 both drive the two transmission gear plates 1301 to move to the side close to the plug ring 7, and the transmission gear plates 1301 are rotated counterclockwise. When moving, 301 drives the pushing column 1302 to move toward the side close to the plug-in ring 7. When moving, the pushing column 1302 squeezes the inner wall of the transmission hole 1203, thereby driving the two plug-in rods 1202 to move toward the side close to each other, and then squeezes the compression spring 1201. At this time, the plug-in ring 7 and the fixing ring 6 can be assembled, and then the rotating column 1305 is rotated in the opposite direction, and then the plug-in rod 1202 is passed through the inside of the socket 9 to complete its fixation, thereby completing the locking of the pipe 5 and the joint 4.

[0037] To sum up: the air sampling pipe connection assembly solves the problem that when sampling air through the equipment, a hose is needed to transfer the sampled air to the storage container. However, if the connection between the hose and the equipment is too loose, the hose will be separated from the equipment, resulting in sampling failure.
