Description

Technical Field

[0001] The utility model relates to the technical field of drainage pipelines, in particular to a water supply and drainage pipeline construction connection device. Background Art

[0002] Drainage pipes refer to the system composed of pipes and ancillary facilities that collect and discharge sewage, wastewater and rainwater, including main pipes, branch pipes and pipes leading to treatment plants. During construction, connecting devices are usually required to connect drainage pipes.

[0003] When using the existing water supply and drainage pipe construction connection device, the staff usually manually presses the drainage pipe against the sealing ring, and then uses the limit device to limit the drainage pipe. However, in actual use, we found that the sealing ring is usually made of deformable rubber material. When limiting the drainage pipe, the drainage pipe and the sealing ring are often not in close contact due to the rebound of the sealing ring, thereby affecting the sealing of the entire connection device. At the same time, manual operation also greatly increases the workload of the staff. Therefore, how to solve this problem is what we need to consider. Utility Model Content

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-Figure 4 , a water supply and drainage pipeline construction connection device, comprising a support plate 1, the upper end of the support plate 1 is fixedly connected to two side plates 2, a bidirectional threaded rod 3 is rotatably connected between the two side plates 2, the two threaded ends of the bidirectional threaded rod 3 have opposite thread directions, a guide rod 4 is fixedly connected between the two side plates 2, the two threaded ends of the bidirectional threaded rod 3 are both threadedly connected to a first connecting plate 5, the middle part of the bidirectional threaded rod 3 is slidably connected to a second connecting plate 6, the guide rod 4 is slidably connected to the two first connecting plates 5 and the second connecting plate 6, the upper end of the second connecting plate 6 is fixedly connected to a first connecting ring 7, and a sealing ring 8 is arranged in the first connecting ring 7;

[0022] Among them, it also includes two limiting components, both of which are used to limit the drainage pipe. The limiting component includes a second connecting ring 9 fixedly connected to the upper end of the first connecting plate 5, and the drainage pipe can be placed in the second connecting ring 9. The inner circle radius of the first connecting ring 7 is equal to the inner circle radius of the two second connecting rings 9. The inner circle of the first connecting ring 7 is aligned with the inner circles of the two second connecting rings 9. The inner top of the second connecting ring 9 is provided with an arc-shaped inner groove, and an arc-shaped pressing plate 10 is arranged in the arc-shaped inner groove. The arc-shaped pressing plate 10 can limit the drainage pipe. The upper end of the second connecting ring 9 is provided with a threaded groove, and the threaded groove is threadedly connected to a limiting screw 11. The lower end of the limiting screw 11 is rotatably connected to the arc-shaped pressing plate 10;

[0023] Among them, it also includes a torsion mechanism, which is used to control the rotation of the bidirectional threaded rod 3. The torsion mechanism includes a rotating handle 12 arranged at the right end of the bidirectional threaded rod 3. A rectangular inner groove 13 is horizontally opened on the right side of the bidirectional threaded rod 3. A rectangular connecting block 14 is fixedly connected to the left side of the rotating handle 12. The left end of the rectangular connecting block 14 passes through the rectangular inner groove 13 and is slidably connected to the inner wall of the rectangular inner groove 13. The left inner wall of the rectangular inner groove 13 is elastically connected to the left side of the rectangular connecting block 14 through a spring 15. The spring 15 can make the annular rubber pad 16 always fit with the side plate 2 on the right side when it is not controlled by humans. The left side of the rotating handle 12 is fixedly connected with the annular rubber pad 16, which fits with the side plate 2 on the right side, which can further improve the stable limiting of the two second connecting rings 9 by the bidirectional threaded rod 3.

[0024] In the utility model, when in use, first limit one of the drainage pipes, insert the drainage pipe from left to right into the second connecting ring 9 on the left side and ensure that the right end of the drainage pipe exceeds the right side of the second connecting ring 9 by a distance, twist the limiting screw 11 on the left side, so that the corresponding arc-shaped pressing plate 10 moves down and tightly abuts against the drainage pipe, thus completing the limiting of one drainage pipe, and similarly, the other drainage pipe can be limited to the second connecting ring 9 on the right side;

[0025] After completing the two limit operations, pull the rotating handle 12 to the right, drive the annular rubber pad 16 to move right, and make it out of contact with the right side plate 2. At this time, the spring 15 will be stretched by force, and then turn the handle 12 to drive the two-way threaded rod 3 to rotate, drive the two first connecting plates 5 to move toward each other, and drive the two drainage pipes to move toward each other. Since the second connecting plate 6 and the two-way threaded rod 3 and the guide rod 4 are all slidingly connected, no matter whether the initial distances between the two drainage pipes and the sealing ring 8 are the same, the two drainage pipes will be tightly against the sealing ring 8 one after another. After the friction, the pulling force on the rotating handle 12 is released. Due to the action of the spring 15, the annular rubber pad 16 is tightly against the right side plate 2, which can further ensure the stable sealing of the two drainage pipes and the sealing ring 8.

[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
