[0027] Correspondingly, in Figure 1 In the example shown, one side wall of plugging disc 8 is rotatably sleeved with screw sleeve 5 one end through bearing, and the other end of screw sleeve 5 penetrates top disc 3 and extends into the inner cavity of plugging rubber barrel 1, in the inner cavity of plugging rubber barrel 1, the inner wall of the other end of screw sleeve 5 away from plugging disc 8 is provided with internal thread, and the outer wall of one end of middle shaft screw 4 towards plugging disc 8 is provided with external thread matched with the internal thread of screw sleeve 5, so that the other end of middle shaft screw 4 towards plugging disc 8 is threadedly sleeved with the other end of screw sleeve 5 away from plugging disc 8, and the other end of middle shaft screw 4 is connected with bottom disc 2 penetrating the inner cavity of plugging rubber barrel 1.

[0028] And the other side wall of the sealing disc 8 is provided with a receiving groove 801 for receiving the rotating wheel 7, and Figure 1 In the example shown, the receiving groove 801 has the same disc structure as the sealing disc 8, but the radius of the receiving groove 801 is smaller than that of the sealing disc 8. It should be noted that although the receiving groove 801 is described as a disc in this example, it is not limited to a disc structure. The receiving groove 801 can also have a rectangular structure, a rhombic structure, an elliptical structure, etc., as long as it can accommodate the rotating wheel 7.

[0029] Correspondingly, one end of the rotating shaft 6 is connected to the side of the rotating wheel 7 facing the sealing disc 8, and the other end of the rotating shaft 6 penetrates the sealing disc 8 and is slidably connected to the inner wall of the screw sleeve 5. The side wall of the screw sleeve 5 is provided with a plurality of axial limiting sliding grooves 9, and the side wall of the rotating shaft 6 is provided with a plurality of limiting protrusions 10 which are inserted into the limiting sliding grooves 9 and are slidably connected to the limiting sliding grooves 9. The relative position of the rotating shaft 6, the rotating wheel 7, the sealing disc 8 and the screw sleeve 5 is limited by the limiting sliding grooves 9 and the limiting protrusions 10.

[0030] In actual use, first, the sealing rubber barrel 1 is inserted into the pipeline to be sealed, and the sealing disc 8 is used to seal the port of the pipeline. The sealing disc 8 is fixed to the pipeline by bolts, so that the device and the pipeline form an integral structure. Pulling the rotating wheel 7 makes the limiting protrusions 10 move in the limiting sliding grooves 9 towards the sealing disc side until the rotating wheel 7 is pulled out of the receiving groove 801. Rotating the rotating wheel 7 drives the rotating shaft 6 and the screw sleeve 5 to rotate synchronously. The middle shaft screw 4 is driven by the screw sleeve 5 to move the bottom disc 2 towards the top disc 3, thereby clamping the two ends of the sealing rubber barrel 1. With the rotation of the rotating wheel 7, the sealing rubber barrel 1 is driven to expand until the outer wall of the sealing rubber barrel 1 abuts against the inner wall of the pipeline, thereby sealing the inner cavity of the pipeline. Then, the rotating wheel 7 is pushed to move the limiting protrusions 10 in the limiting sliding grooves 9 away from the sealing disc side until the rotating wheel 7 returns to the receiving groove 801.

[0031] The application sets the slidingly connected rotating shaft 6, so that the distance between the rotating wheel 7 and the sealing disc 8 can be adjusted. The application also sets the appropriate receiving groove 801 to accommodate the rotating wheel 7, greatly reducing the possibility of the rotating wheel 7 colliding with external objects, thereby avoiding the possibility of affecting the sealing effect of the sealing rubber barrel 1 due to external collision driving the rotating wheel 7 to rotate after sealing the pipeline.

[0034] Specifically, in order to further improve the firmness of the runner 7 placed in the receiving groove 801 and at the same time ensure the convenience in the pushing and pulling process of the runner 7, different magnets are respectively embedded in the inner parts of the butt blocks 11 and the insertion blocks 704.

[0035] Reference Figure 4 The shaft 6 is provided with a through cavity coaxially arranged with the shaft 6 and penetrating through both ends of the shaft 6, and the one end of the central shaft screw 4 coaxially connected with the runner 7 is connected with a scale shaft 12, and the outer wall of the scale shaft 12 is slidingly sleeved with the inner wall of the through cavity. During the process of moving the bottom disc 2 and the central shaft screw 4 to the side of the top disc 3 by rotating the runner 7, the staff can directly judge the distance between the bottom disc 2 and the top disc 3 by observing the free end of the scale shaft 12, and then the degree of formation of the blocking rubber bucket 1 is judged, and the convenience of the use of the device is improved.

[0036] Exemplarily, in order to better cooperate with the overall structure, the overall length of the scale shaft 12 and the central shaft screw 4 is limited, so that when the blocking rubber bucket 1 is compressed to a predetermined state and the insertion block 704 is received into the butt cavity, the end of the free end of the scale shaft 12 is flush with the end of the inner ring block 701.

[0037] Correspondingly, it also includes a sliding clamping block 13, and the sliding clamping block 13 is provided with a sliding groove 14;

[0038] The free end of the scale shaft 12 is provided with a groove, and a rotating rod sleeved in the sliding groove 14 is arranged in the inner cavity of the groove, and the distance between at least one end wall of the sliding clamping block 13 and the same direction inner wall of the sliding groove 14 is smaller than the distance between the rotating rod and the inner bottom surface of the groove, so that the sliding clamping block 13 rotates around the rotating rod as the center;

[0039] At the same time, the end of the inner ring block 701 is provided with a clamping groove 15 with the same depth as the groove, and the distance between the bottom disc 2 and the top disc 3 and the thread between the central shaft screw 4 and the screw sleeve 5 are pre-set, so that when the insertion block 704 is received into the butt cavity and the sliding clamping block 13 rotates around the rotating rod to be perpendicular to the scale shaft 12, the sliding clamping block 13 is received into the clamping groove 15, and the sliding clamping block 13 is limited by the clamping groove 15, and the central shaft screw 4 is further limited, so that the rotation of the central shaft screw 4 does not affect the blocking effect of the blocking rubber bucket 1.
