The pressing block 322 is mounted on one side of the rubber 321 away from the mounting hole 312. Referring to fig. 10, the rotating member 323 includes a second through hole 324 and a relief hole 325, and the relief hole 325 penetrates a wall of the rotating member 323 and communicates with the second through hole 324.

The plurality of groups of rubber pieces 321 and the pressing blocks 322 are arranged in the circumferential direction of the pipeline connecting device, and the plurality of rubber pieces 321 are used for sucking the external pipeline together, so that the contact area and the contact position of the pipeline connecting device and the connection of the external pipeline can be increased, and the reliability of the connection of the pipeline connecting device and the external pipeline is greatly improved.
Referring to fig. 4, in some embodiments, the rotating member 323 is uniformly provided with a plurality of relief holes 325 along the circumferential direction of the rotating member 323. Each of the compacts 322 corresponds to one of the relief holes 325. That is, in the locked state, all of the press pieces 322 simultaneously avoid all of the escape holes 325. In the unlocked state, one of the compacts 322 is located in each of the escape holes 325. In other embodiments, the press blocks 322 and the relief holes 325 are not in one-to-one correspondence, and it is also possible that the number of relief holes 325 is greater than the number of press blocks 322. In the introduced state, only a portion of the escape holes 325 have the press pieces 322 therein. This way locking and unlocking of the line connection and the external line can likewise be achieved.

The fitting projection 326 is a projection of the inner wall of the rotating member 323. During rotation of the rotating member 323, the movement path of the engaging protrusion 326 passes through the pressing block 322. When the engaging protrusion 326 is pressed against the pressing block 322, the pressing block 322 is pressed toward the radial direction of the pipe connection device, and the rubber member 321 is also moved toward the central axis of the pipe connection device, so that the gas between the cavity M of the rubber member 321 and the external pipe is discharged, the rubber member 321 is sucked against the external pipe, at this time, the rubber member 321 plays a role like a suction cup, the friction between the rubber member 321 and the external pipe is increased, the contact area is also increased due to the deformation of the rubber member 321, and the external pipe is difficult to be separated, thereby playing a role of improving the locking effect.
