[0023] Please refer to Figures 1-4, the present utility model provides a technical solution: a municipal sewage drainage pipe fitting, which includes a first connecting pipe 1, a second connecting pipe 2 and a rubber gasket 3. Four groups of rectangular grooves 4 are provided on the outer surfaces of both the first connecting pipe 1 and the rubber gasket 3. Eight groups of limiting holes 5 are provided on the right side surfaces of both the first connecting pipe 1 and the rubber gasket 3. Eight groups of limiting shafts 6 adapted to the eight groups of limiting holes 5 are fixedly connected to the left side surface of the second connecting pipe 2. Four groups of fixing blocks 7 in the shape of triangular prisms are fixedly connected to the inner wall of the right side of the first connecting pipe 1. An annular sliding groove 8 is provided on the outer surface of the second connecting pipe 2. A rotating ring 9 is rotatably connected inside the annular sliding groove 8.

A supporting block 12 is fixedly connected to the outer surface of the second connecting pipe 2. A rotating shaft 13 is rotatably connected inside the supporting block 12 through a bearing. A transmission assembly is installed at the left end of the rotating shaft 13. The transmission assembly includes a transmission gear 14 fixedly sleeved on the left end of the rotating shaft 13 and teeth fixed on the right side of the outer surface of the rotating ring 9. The transmission gear 14 meshes with the teeth. The materials of both the transmission gear 14 and the teeth are cast iron. A driving assembly is installed on the outer surface of the second connecting pipe 2. The driving assembly includes a fixed cylinder 15 fixedly installed on the outer surface of the second connecting pipe 2 and a worm gear 16 fixedly sleeved on the right end of the rotating shaft 13. A round shaft 17 is rotatably connected inside the fixed cylinder 15 through a bearing. A worm 18 meshing with the worm gear 16 is fixedly sleeved on the outer surface of the round shaft 17. A control lever is fixedly inserted at the top of the round shaft 17.

[0024] In the present utility model, in order to enable the limiting shaft 6 to stably limit the first connecting pipe 1 and the second connecting pipe 2, the material of the limiting shaft 6 is set to stainless steel, thereby improving the service life of the limiting shaft 6. And eight groups of limiting shafts 6 are arranged in a circular array centered on the center line of the second connecting pipe 2, so that the eight groups of limiting shafts 6 can evenly and effectively limit the first connecting pipe 1 and the second connecting pipe 2, and relatively effectively improve the convenience of the limiting shaft 6 to limit the first connecting pipe 1 and the second connecting pipe 2.

[0025] In the present utility model, in order to enable the control lever to smoothly drive the round shaft 17 and the worm 18 to rotate, the shape of the control lever is set to be cylindrical, and the included angle between the center line of the control lever and the center line of the round shaft 17 is 90 degrees, so that the control lever can evenly and effectively apply the acting force to the round shaft 17, greatly improving the smoothness of the control lever driving the round shaft 17 and the worm 18 to rotate.

[0026] In the present utility model, in order to enable the limiting shaft 6 to pass through the limiting hole 5 conveniently, the outer diameter of the limiting shaft 6 is set to be smaller than the inner diameter of the limiting hole 5. The edges of the left side surface of each group of limiting shafts 6 are all chamfered, and the radius of the chamfer is one millimeter, so that the limiting shaft 6 can flexibly cross the limiting hole 5, effectively improving the convenience of the butt joint between the first connecting pipe 1 and the second connecting pipe 2.

[0027] The electrical components mentioned in this article are all electrically connected to the external main controller and 220V mains power, and the main controller can be a conventional known device such as a computer for control.

[0028] The working principle of the present utility model is as follows:

[0029] S1. Butt-join the first connecting pipe 1 and the second connecting pipe 2, align the limiting shaft 6 with the limiting holes 5 on the first connecting pipe 1 and the rubber pad 3, and align the driving frame 10 with the rectangular grooves 4 on the first connecting pipe 1 and the rubber pad 3. Make the second connecting pipe 2 drive the rotating ring 9, the driving frame 10 and the driving block 11 to move leftward relative to the first connecting pipe 1. When the limiting shaft 6 is inserted into the limiting hole 5 and the opposite surfaces of the first connecting pipe 1 and the second connecting pipe 2 are both in contact with the outer surface of the rubber pad 3, turn the operating rod.

[0030] S2. Fix the first connecting pipe 1 and the second connecting pipe 2. After turning the operating rod, the operating rod drives the round shaft 17 and the worm 18 to rotate counterclockwise. The worm 18 meshes with the worm wheel 16 for transmission, so that the worm wheel 16 drives the rotating shaft 13 and the transmission gear 14 to rotate clockwise. The transmission gear 14 meshes with the gear teeth for transmission, so that the transmission gear 14 drives the rotating ring 9, the four groups of driving frames 10 and the four groups of driving blocks 11 to rotate counterclockwise along the track of the annular sliding groove 8 at the same time. The four groups of driving blocks 11 are respectively adapted to the four groups of fixing blocks 7 at the same time. Since the shapes of the driving block 11 and the fixing block 7 are both triangular prisms, when the driving block 11 rotates counterclockwise, the opposite surfaces of the driving block 11 and the fixing block 7 mutually extrude and apply forces, so that the driving block 11 can drive the driving frame 10, the rotating ring 9 and the second connecting pipe 2 to move leftward relative to the first connecting pipe 1 to squeeze the rubber pad 3, thereby stably fixing the first connecting pipe 1 and the second connecting pipe 2.

[0031] In summary, for this municipal sewage drainage pipe fitting, after the first connecting pipe 1 and the second connecting pipe 2 are butted and the control rod is turned, the worm 18 can be stably and effectively meshed with the worm wheel 16 for transmission, so that the driving frame 10 can stably and effectively drive the driving block 11 to rotate along the track of the annular sliding groove 8 as the rotating ring 9 rotates. During the movement of the driving block 11, it fits with the fixed block 7, so that the driving block 11 can stably apply a force to the driving frame 10, the rotating ring 9 and the second connecting pipe 2, which effectively improves the convenience of installing the first connecting pipe 1 and the second connecting pipe 2. It takes less time and effectively avoids the situation of affecting traffic. By setting the transmission gear 14 to be meshed with the gear teeth for transmission, the gear teeth can stably and effectively drive the four groups of driving frames 10 and the four groups of driving blocks 11 to rotate simultaneously. During the movement of the four groups of driving blocks 11, they respectively fit with the four groups of fixed blocks 7 at the same time, so that the four groups of driving blocks 11 and the four groups of driving frames 10 can apply forces to the rotating ring 9 and the second connecting pipe 2 at the same time, which effectively improves the tightness of installing the first connecting pipe 1 and the second connecting pipe 2. By setting the limiting shaft 6 to fit with the limiting holes 5 on the first connecting pipe 1 and the rubber pad 3, the first connecting pipe 1 and the second connecting pipe 2 can be butted conveniently, which effectively improves the accuracy of butting the first connecting pipe 1 and the second connecting pipe 2. And under the action of the rectangular groove 4, the driving frame 10 and the driving block 11 can conveniently cross over the first connecting pipe 1, so that the driving block 11 can be more conveniently adapted to the fixed block 7, further improving the convenience of connecting the first connecting pipe 1 and the second connecting pipe 2.
