However, the specific embodiments given by the applicant should not be regarded as a limitation to the technical solution of the utility model. Any change in the definition of components or technical features and / or any formal but not substantial transformation of the overall structure should be regarded as the protection scope defined by the technical solution of the utility model.

[0020] See Figures 1 to 2 as shown, the technical solution of the utility model is as follows:

[0021] A die suspension plugging tool for indoor sewer holes. The die suspension plugging tool is arranged on the bottom surface of the hole 1. The die suspension plugging tool includes a left mold 6 and a right mold 7 with the same structure. Both the left mold 6 and the right mold 7 are integrally formed of plastic material. Both the left mold 6 and the right mold 7 include a semi-circular ring plate 2. An arc plate 3 extending downward is arranged on the inner ring of the bottom surface of the semi-circular ring plate 2. The arc plate 3 is consistent with the radian of the inner ring of the semi-circular ring plate 2. First rib plates 4 are connected to both the upper end and the lower end of the arc plate 3. The two first rib plates 4, the arc plate 3 and the semi-circular ring plate 2 are integrally formed. The first rib plates 4 are all fixed on the bottom surface of the semi-circular ring plate 2. The two first rib plates 4 support the semi-circular ring plate 2 and reduce the risk of the semi-circular ring plate 2 breaking. The two semi-circular ring plates 2 are butted and jointly abutted against the bottom surface of the hole 1. A through hole 5 adapted to the outer diameter of the indoor sewer pipe 19 is formed by the two semi-circular ring plates 2. The inner diameter of the through hole 5 is consistent with the outer diameter of the indoor sewer pipe 19, avoiding the diameter of the through hole 5 being too large and the slurry leaking along the gap between the through hole 5 and the indoor sewer pipe 19. The indoor sewer pipe 19 is located in the hole 1 and passes downward through the through hole 5. The two arc plates 3 are both attached to the outer surface of the indoor sewer pipe 19. Fastening parts are jointly arranged on the two first rib plates 4 on the same side. Fastening bolt groups for connecting and fixing the two semi-circular ring plates 2 on the indoor sewer pipe 19 are installed on the fastening parts. The two semi-circular ring plates 2 are fixed on the indoor sewer pipe 19 relying on the indoor sewer pipe 19 to prevent the left mold 6 and the right mold 7 from sliding downward and causing slurry leakage.

[0022] A ring-shaped sealing gasket 8 is clamped between the two semi-circular ring plates 2 and the bottom surface of the hole 1. The ring-shaped sealing gasket 8 is integrally formed of rubber material. The inner diameter of the ring-shaped sealing gasket 8 is adapted to the outer diameter of the indoor sewer pipe 19. The indoor sewer pipe 19 is inserted into the inner ring of the ring-shaped sealing gasket 8. Through the above-mentioned ring-shaped sealing gasket 8, the gap between the bottom surface of the hole 1 and the two semi-circular ring plates 2 is plugged, improving the sealing performance, reducing the risk of slurry leakage, and at the same time facilitating the disassembly of the die suspension plugging tool after the plugging construction of the hole 1 is completed, avoiding the left mold 6 and the right mold 7 from adhering to the slurry.

[0023] The fastening part includes a left open slot 9 and a right open slot 10. Both the left open slot 9 and the right open slot 10 are integrally formed with the left mold 6 or the right mold 7. The left open slot 9 is fixed on the left side of the first rib plate 4 of the left mold 6, and the right open slot 10 is fixed on the right side of the first rib plate 4 of the right mold 7. A channel 11 penetrating through the two first rib plates 4 is commonly provided on the left open slot 9 and the right open slot 10. The channel 11 is in an open shape and the opening faces outward. The fastening bolt group includes a fastening bolt 12. One end of the fastening bolt 12 is rotatably connected to the left open slot 9. The fastening bolt 12 is placed in the channel 11 and the other end extends out of the right open slot 10. A fastening nut 13 is installed on the other end of the fastening bolt 12. A steel gasket 14 is clamped between the right open slot 10 and the fastening nut 13. Through the above structural arrangement, the fastening bolt group is connected to the fastening part. By screwing the fastening nut 13 on the fastening bolt group, the two semi-circular ring plates 2 are connected or separated, which is beneficial to the installation and disassembly of the semi-circular ring plates 2.

[0024] A vertically penetrating vertical hole is commonly provided on the end of the left open slot 9 and the fastening bolt 12. A hairpin pin 15 is installed in the vertical hole. The fastening bolt 12 is fixed on the left open slot 9 through the hairpin pin 15, and at the same time, it also ensures that the end of the fastening bolt 12 rotates around the hairpin pin 15.

[0025] A groove 16 is provided on the docking side of one of the semi-circular ring plates 2, and a boss 17 adapted to the groove 16 is provided on the docking side of the other semi-circular ring plate 2. The boss 17 is inserted into the groove 16. Through the cooperation of the boss 17 and the groove 16, the two semi-circular ring plates 2 are tightly connected together, which not only strengthens the firmness of the connection between the two semi-circular rings but also reduces the risk of slurry leakage along the docking seam of the two semi-circular ring plates 2.

[0026] A number of second rib plates 18 are fixed in the middle of the outer arc surface of the arc plate 3. The number of the second rib plates 18 is determined according to actual needs. The number of second rib plates 18 is fixed on the bottom surface of the semi-circular ring plate 2. The second rib plates 18 are integrally formed with the arc plate 3 and the semi-circular ring plate 2. The number of second rib plates 18 is provided between the two first rib plates 4, and adjacent second rib plates 18 are spaced apart from each other. Through the above second rib plates 18, the strength of the semi-circular ring plate 2 is strengthened, which plays a supporting role for the semi-circular ring plate 2 and reduces the risk of fracture of the semi-circular ring plate 2.

[0027] The utility model comprises two parts, namely a left mold 6 and a right mold 7. The left mold 6 and the right mold 7 jointly abut against the bottom surface of the hole 1. The left mold 6 and the right mold 7 are butted and surrounded and fixed on the indoor sewer pipe 19 to realize the plugging of the hole 1, solving the defect of the plugging method of the multi-layer board hanging mold for the hole 1. The left mold 6 and the right mold 7 are connected and fixed on the indoor sewer pipe 19 through a fastening bolt group. Not only is the connection structure stable, but also the installation and disassembly are simple and convenient. The hanging mold plugging tool can be reused multiple times, meeting the requirements of energy conservation and environmental protection. The left mold 6 and the right mold 7 have simple structures and low production costs. The hanging mold plugging tool not only reduces the risk of slurry leakage, but also avoids the defect of slurry leakage polluting the ceiling of the household, ensuring the quality of the plugging construction of the hole 1, and has been well applied in the actual construction process and recognized by all parties and residents.
