They include pipe clamps, internal pipe clamps, reducers, flexible joints and quick connectors. Pipe connectors are made of many materials and can be used under different conditions. The most important thing about pipe connectors is that they are easy to connect.

[0003] For example, a pipe connector with publication number CN105736886A includes a connecting pipe, a connecting head and a fixing ring. One end of the connecting head is provided with a thread. The connecting head cooperates with a sealing ring to be sealed and threaded with the connecting pipe, and the fixing ring is clamped on the outside of the connecting pipe. This invention has the advantages of low cost, easy installation, simple structure and high sealing level.

However, only a single sealing ring is set at the connecting pipe and the connector head for sealing. As the sealing ring is used, it is subject to wear and corrosion at the connecting pipe and the connecting head, and its sealing performance will be reduced. Moreover, when the connecting pipe is screwed to the connecting head, the fixing ring is blocked by the protrusion, and it is not easy to disassemble and replace the internal sealing ring. In view of this, it is very necessary to design a pipe connection device with good sealing performance to solve this problem. Utility Model Content

[0008] Preferably, the other ends of the left and right cross bars are fixedly connected with second stoppers, and the outer wall of the second stoppers is gap-matched with the inner wall of the cylinder.

[0009] Preferably, a spring is installed inside the cylinder, and two ends of the spring are connected to the second stopper and the cylinder respectively.

[0010] Preferably, the fixing mechanism includes a plurality of screws fixedly connected to the outer wall of the connecting head, and the outer wall of the screw is gap-matched with the inner wall of the through hole of the second disc, the outer wall of the screw is threadedly connected with a nut, the outer wall of the screw is sleeved with a gasket, and the two ends of the gasket are respectively fitted with the nut and the outer wall of the second disc.

[0011] Beneficial Effects

[0012] The utility model provides a pipeline connection device with good sealing performance, which has the following beneficial effects:

[0013] When it is necessary to use this device, the first sealing ring can be installed inside the connecting pipe, the first disc can be used to block the first sealing ring, and then the second sealing ring can be sleeved onto the pipe to drive the pipe to move, so that the pipe enters the connecting pipe and fits with the first sealing ring.
