By adopting the above technical solution, after the connecting ring is screwed on the fixing ring, the fixing bolt is rotated so that one end of the fixing bolt abuts against the outer wall of the pipeline, thereby further increasing the stability between the pipeline and the connecting ring.

Preferably, a sealing ring is sheathed on the peripheral side of the inclined surface, and the outer wall of the sealing ring abuts against the inner wall of the pipeline.

By adopting the above-mentioned technical scheme, when installing the fixed ring, the sealing ring is placed on the peripheral side of the beveled surface of the fixed ring, and then inserted into the inner peripheral side of the pipeline under the action of the beveled surface, and the sealing ring can increase the connection between the fixed ring and the pipe. tightness between roads.

Preferably, a first rotating nut is sheathed in the middle of the outer peripheral side of the fixing ring, and a second rotating nut is sheathed in the outer peripheral side of the connecting ring away from the end of the pipeline.

By adopting the above technical solution, when the fixed ring and the connecting ring are fixed, the first rotating nut is screwed by a tool, and the second rotating nut is fixed by a tool at the same time, so that the connecting ring and the fixing ring are interacted by threads, The fixing ring is connected and fixed with the connecting ring.

In summary, the present application includes at least one of the following beneficial technical effects:

1. Under the action of multiple top cones, it can prevent the pipeline from detaching from the connecting ring and the fixed ring, and increase the stability of the pipeline between the connecting ring and the fixed ring;

2. After the thread of the connecting ring is rotated on the fixing ring, turn the fixing bolt so that one end of the fixing bolt abuts against the outer wall of the pipeline, thereby further increasing the stability between the pipeline and the connecting ring;

3. The first rotating nut is screwed by the tool, and the second rotating nut is fixed by the tool at the same time, so that the connecting ring and the fixing ring are interacted by threads, so that the fixing ring and the connecting ring are connected and fixed.
