The side of the lower pressure plate 5 close to the fixed pressure block 7 is fixedly connected with the movable pressure block 6. The movable pressure block 6 is far away from the lower pressure plate. One side of 5 is a tapered arc surface, and one end of the lower pressure plate 5 away from the movable pressure block 6 extends out of the outer surface of the connecting member body 1. The movable pressure block 6 and the fixed pressure block 7 are arranged oppositely, and the outer surfaces of the two reinforcing ribs 2 Both are fixedly connected with a fixed base 8. The fixed base 8 is provided with a rotating shaft movable hole 12. The rotating shaft movable hole 12 is a through hole. An eccentric wheel rotating shaft 9 is rotatably connected between the two rotating shaft movable holes 12. The outer surface of the eccentric wheel rotating shaft 9 The surface fixed sleeve is provided with an eccentric cam 11. The outer surface of the eccentric shaft 9 is fixedly connected with an eccentric handle 10. The eccentric handle 10 is U-shaped. The eccentric cam 11 is located in the eccentric handle 10. The eccentric handle 10 is eccentric. The side is perpendicular to the bottom of the eccentric handle 10. Two flanges 13 are provided in the connecting member body 1. Fixed holes 16 are evenly provided on the outer surface of the flange 13. A butterfly valve is fixedly connected to the left surface of the left flange 13. The body 15 and the outer surface of the right flange 13 are fixedly connected to the pipe 14. When in use, the flange 13 on the butterfly valve body 15 and the flange 13 on the pipe 14 are aligned, and then the two flanges 13 are The corresponding fixing holes 16 on the top are also aligned with each other, and then snap the connecting member body 1 into the outer surfaces of the two flanges 13, and connect the fixing pressure block 7 in the connecting member body 1 with the fixing holes on the left flange 13 16 are aligned, and then the operator manually pulls one end of the eccentric handle 10 to rotate the eccentric handle 10 90° to the right. When the eccentric handle 10 rotates, it drives the eccentric shaft 9 on it to move through the two rotating shaft movable holes 12 Internal rotation, through the rotation of the eccentric shaft 9, drives the eccentric cam 11 fixed on it to rotate with the center of the circle of the movable hole 12 of the shaft as the axis.

By setting the opposite surfaces of the movable pressure block 6 and the fixed pressure block 7 as conical arc surfaces, the flange 13 can be mounted on the flange 13. The fixing holes 16 can be aligned and locked, so that the two flanges 13 can not only be firmly fixed in the radial direction, but also well fixed in the axial direction, preventing the pipe 14 from being subject to external rotational force and causing the flange 13 to The connection may become loose.

The fixed eccentric cam 11 rotates with the center of the circle of the movable hole 12 of the rotating shaft as the axis. When the eccentric cam 11 rotates with the center of the circle of the movable hole 12 of the rotating shaft as the axis, the convex eccentric part of the eccentric cam 11 gradually moves down the pressure plate 5 away from the movable pressure. One end of the block 6 approaches until the raised eccentric part of the eccentric cam 11 contacts the end of the lower pressure plate 5 away from the movable pressure block 6, and then the rotation of the eccentric handle 10 causes the eccentric cam 11 to continue to move away from the lower pressure plate 5 and the movable pressure block 6. One end of the block 6 exerts a force to the right, and the end of the lower pressure plate 5 away from the movable pressure block 6 receives the force transmitted from the eccentric cam 11, and is limited by the pressure plate rotating shaft 4 to rotate, thus driving the lower pressure plate. The movable pressing block 6 on 5 rotates to the left with the axis of the pressing plate rotating shaft 4 as the center of the circle. At the same time, the movable pressing block 6 also gradually approaches the fixed pressing block 7. While the movable pressing block 6 approaches the fixed pressing block 7, it moves towards the pipe 14. The flange 13 on the upper body exerts force, and at the same time, the flange 13 is deflected by the force of the movable pressure block 6, so that the movable pressure block 6 can be clamped into the fixing hole 16 on the flange 13, thereby connecting the two sides. The fixing holes 16 on each flange plate 13 are aligned and locked. At this time, the eccentric handle 10 is rotated 90° to the right. Repeat the operation until the fixing holes 16 on the flange plate 13 are all fixed, and then the installation can be completed. , and when it is necessary to inspect the butterfly valve body 15, pull the eccentric handle 10 in the opposite direction, and then rotate the eccentric handle 10 90° to the left, and then the movable pressure block 6 can lock the two flanges 13.
