A water supply and drainage pipe connection device

Technical Field

The utility model belongs to the field of water supply and drainage pipelines, in particular to a water supply and drainage pipeline connecting device.

Background Art

Drainage pipes refer to a system composed of pipes and their ancillary facilities that collect and discharge sewage, wastewater and rainwater, including main pipes, branch pipes and pipes leading to treatment plants. When laying the pipes, connecting devices are required to connect them. Due to their long-term exposure to a humid environment, the connected parts are prone to aging, which makes it easy for the water inside to leak out, and the connection parts are not firm. The State Intellectual Property Office issued an authorization announcement on July 28, 2023, with the authorization announcement number CN219432691U: "A water supply and drainage pipe connection device". The patent discloses a device that can connect pipes, but when the device is in use, multiple sets of bolts need to be turned to achieve horizontal and vertical clamping of the pipe, and the operation is relatively complicated. Therefore, we designed a water supply and drainage pipe connection device.

A water supply and drainage pipe connection device, as shown in Figure 1, comprises an inner pipe 1, and the outer peripheries of both ends of the inner pipe 1 are respectively provided with drainage pipes 2 in airtight sliding cooperation, characterized in that: a convex edge 3 is fixedly provided on the outer periphery of the middle part of the inner pipe 1, and the outer periphery of the convex edge 3 is provided with threads, and the two ends of the convex edge 3 are respectively fixed with sealing pads 4, and the ends of the drainage pipes 2 close to each other are respectively closely contacted and cooperated with the sealing pads 4, and the outer periphery of the drainage pipes 2 is respectively provided with outer pipes 5 in sliding cooperation, and the ends of the outer pipes 5 close to each other are respectively provided with internal thread grooves 6, and the internal thread grooves 6 can respectively cooperate with the threads of the outer periphery of the convex edge 3, and the outer pipes 5 are respectively provided with a plurality of threaded holes 7 with the bottoms inclined toward the convex edge 3, and the threaded holes 7 are respectively provided with threaded rods 8 in thread cooperation, and the inner ends of the threaded rods 8 can respectively contact and cooperate with the outer peripheries of the corresponding drainage pipes 2. The utility model has a simple structure and an ingenious design. By twisting a group of threaded rods 8, the horizontal and vertical clamping of the drainage pipes 2 can be realized, which is more convenient to use, can improve work efficiency, has a better sealing effect, can meet market demand, and is suitable for promotion. When using the utility model, firstly, the outer circumferences of the drainage pipes 2 that need to be connected are respectively covered with the outer tubes 5, the inner tube 1 is placed in the middle of the two drainage pipes 2, and the drainage pipes 2 on both sides are respectively covered on the two ends of the inner tube 1. The inner tube 1 forms a good support for the drainage pipes 2 to prevent the ends of the drainage pipes 2 from collapsing inward, and the ends of the drainage pipes 2 that are close to each other are respectively in contact with the sealing gaskets 4 on the flange 3. The outer tube 5 on the drainage pipes 2 is screwed so that the internal thread groove 6 is installed together with the threads on the outer circumference of the flange 3. At this time, the threaded rod 8 on the outer tube 5 is screwed, and the bottom end of the threaded rod 8 is in contact with the outer circumference of the soft drainage pipe 2. While vertically clamping the drainage pipes 2, the drainage pipes 2 can be driven to move closer to the inside, so that the ends of the drainage pipes 2 that are close to each other can be in close contact with the sealing gasket 4, thereby improving the sealing effect.

Specifically, as shown in the figure, the two ends of the inner tube 1 in this embodiment are inclined surfaces with a narrow inner side and a wide outer side. When the water in the drainage pipe 2 flows from one side to the other side, the wall thickness at the two ends of the inner tube 1 will prevent the water from being blocked, thereby affecting the water flow speed.

Specifically, as shown in the figure, first annular grooves 30 are respectively provided at both ends of the inner tube 1 of the present embodiment, and rubber rings 31 are respectively provided in the first annular grooves 30, and the rubber rings 31 can respectively slide in airtight cooperation with the inner circumference of the corresponding drainage pipe 2. The rubber rings 31 can increase the sealing between the inner tube 1 and the drainage pipe 2.

Further, as shown in the figure, one end of the outer tube 5 of this embodiment is respectively provided with a second annular groove 40, and a rubber ring 31 is also respectively provided in the second annular groove 40, and the rubber ring 31 can respectively slide with the outer periphery of the corresponding drainage pipe 2 in an airtight manner. The rubber ring 31 can increase the sealing between the outer tube 5 and the drainage pipe 2.

Furthermore, as shown in the figure, the ends of the drainage pipes 2 close to each other in this embodiment are respectively provided with protrusions, and one side of the internal thread groove 6 can respectively abut against and contact with the corresponding protrusions. When the internal thread groove 6 is matched with the outer peripheral thread of the convex edge 3, the internal thread groove 6 can squeeze the protrusion of the drainage pipe 2 inward, so that the ends of the drainage pipes 2 close to each other can be closely contacted and matched with the sealing gasket 4.

Furthermore, as shown in the figure, one end of the threaded rod 8 in this embodiment is respectively fixedly mounted with a hand wheel 60. Rotating the threaded rod 8 by rotating the hand wheel 60 is more convenient and labor-saving.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it.
