Detailed Description
The embodiment of the multi-seal quick-plug connector for corrugated stainless steel pipe of the present invention is further described with reference to fig. 1 to 3.
Many sealed types of inserting soon of nonrust corrugated steel pipe connect, including bellows loose joint 9 and nut 12, the one end of bellows loose joint 9 is equipped with first connection external screw thread 8, the other end is equipped with second connection external screw thread 11, the one end inner wall of nut 12 is equipped with first connection internal thread 4 in proper order, connect anchor ring 14 and extrusion ring inclined plane 1, the diameter that the one end of connecting anchor ring 14 was kept away from to extrusion ring inclined plane 1 is less than the diameter of the other end, extrusion nut 12 is through first connection internal thread 4 and the first connection external screw thread 8 threaded connection of bellows loose joint 9, bellows loose joint 9 is equipped with the rubber pad in proper order between side and the extrusion ring inclined plane 1 of extrusion ring inclined plane 1 towards extrusion ring inclined plane 1, rand 3 and ring spring 2, extrusion ring inclined plane 1 blocks the bellows that will pass nut 12 through extrusion ring spring 2.
As shown in fig. 3, the rubber pad comprises a connecting barrel 6, an inner ring 15 is arranged at one end of the connecting barrel 6, an outer ring 5 is arranged at the other end of the connecting barrel 6, the inner ring 15 and the outer ring 5 are integrally formed, a mounting groove 13 is arranged at one end of a bellows loose joint 9 connected with a nut 12, the connecting barrel 6 and the mounting groove 13 are connected, the outer ring 5 and the bellows loose joint 9 are abutted to the side face of the extrusion ring inclined plane 1, and the inner ring 15 is abutted to the bottom face of the mounting groove 13.
