[0002] Drainage pipes refer to the system of pipes and their ancillary facilities that collect and discharge sewage, wastewater and rainwater. They include main pipes, branch pipes and pipes leading to treatment plants. They are responsible for collecting sewage, wastewater and rainwater inside and outside buildings and discharging them in an orderly manner to sewage treatment plants or natural water bodies to ensure environmental hygiene and dryness, and to prevent water accumulation and sewage overflow from causing environmental pollution and inconvenience to life. During the installation of drainage pipes, fastening equipment is a key component to ensure that the pipe connections are firm and the operation is stable. It can effectively prevent the pipes from loosening, shifting, or even leaking due to water pressure, self-weight, temperature changes, or external impact. It fixes the pipes to the wall, floor, ceiling, or brackets, restricts the lateral and longitudinal displacement of the pipes, distributes the weight of the pipes, and avoids loosening of the joints due to long-term stress. In the installation of water supply and drainage pipes, some equipment uses a fixed method to connect the pipe fixing structure and the base. The fixing structure and the base are usually connected at a vertical angle, and the angle cannot be adjusted. It is suitable for scenarios where the pipe route is simple and the angle is fixed, which limits the scope of use. Utility Model Content

[0013] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0014] Please see Figure 1-4 This utility model provides a fastening device for building water supply and drainage pipes, including a mounting base plate 1. The mounting base plate 1 has first mounting holes 2 at its corners. When fixing the mounting base plate 1, matching bolts pass through the first mounting holes 2 to fix it in a suitable position. A connecting base 3 is fixedly connected to the top center of the mounting base plate 1. Angle positioning holes 4 are formed at equal angles at the top edge of the connecting base 3. A first rotating connector 5 is rotatably connected to the top of the connecting base 3. A rotating cross 6 is rotatably connected to the top of the first rotating connector 5. A rotating connecting groove 14 is formed at the bottom of the rotating cross 6. The rotating connecting groove 14 and the first rotating connector 5 at the top of the connecting base 3 are rotatably matched. A horizontal rotating angle positioning component is fixedly connected to the top of the rotating cross 6. An angle adjusting plate 8 is fixedly connected to the top of the positioning component. A guide rail 16 is symmetrically fixedly connected to the top of the angle adjusting plate 8. A docking component is symmetrically slidably connected to both ends of the guide rail 16. A fastening component is movably connected to the top of the docking component. Second mounting holes 9 are formed inside both the rotating cross 6 and the angle adjusting plate 8. A longitudinal angle locking component is fixedly installed inside each of the two second mounting holes 9.
[0015] Furthermore, the horizontal rotation angle positioning assembly includes a positioning bolt 15, which is threadedly connected to the middle of the rotating cross 6 and passes through the rotating cross 6. The positioning bolt 15 matches the angle positioning hole 4. A universal connector 7 is fixedly connected to the top center of the rotating cross 6. When it is necessary to adjust the orientation of the rotating cross 6, the positioning bolt 15 is first removed from the angle positioning hole 4, and then the rotating cross 6 is turned so that it rotates. At this time, the first rotating connector 5 rotates inside the rotating connecting groove 14. After rotating to the appropriate position, the positioning bolt 15 rotates so that it enters the angle positioning hole 4, thus completing the fixation of the rotating cross 6. During this process, the universal connector 7 rotates accordingly.
[0016] Furthermore, the docking assembly includes two sliding frames 17, which are symmetrically slidably connected to the ends of two guide rails 16. Each of the two sliding frames 17 has a fixed arc-shaped frame 18 fixedly connected to its top, and each of the two guide rails 16 has a longitudinal positioning hole 21 at its top.
[0017] Furthermore, the fastening assembly includes two movable locking top covers 22, which are movably connected to the tops of two fixed arc-shaped frames 18 respectively. Connecting horizontal plates 19 are fixedly connected to both sides of the two movable locking top covers 22 and the fixed arc-shaped frames 18. A positioning screw 20 is threadedly connected to the middle of the top of the connecting horizontal plate 19 on the side of the movable locking top cover 22. The positioning screw 20 passes through the sliding frame 17, is inserted into the longitudinal positioning hole 21, and is screwed into it.
[0018] Furthermore, each of the two movable locking top covers 22 and the fixed arc frame 18 has a docking groove 25 on the side close to each other. A drain pipe body 23 is movably inserted into the docking groove 25. A sealing gasket 26 is movably connected to the end of the two drain pipe bodies 23 close to each other. A two-way fastening screw 24 is symmetrically inserted between the two movable locking top covers 22 and the fixed arc frame 18. Nuts are threaded at both ends of the two-way fastening screw 24, and the end face of the nut contacts the side of the fixed arc frame 18 and the movable locking top cover 22.
[0019] Furthermore, the longitudinal angle locking assembly includes four second rotating connectors 10, which are symmetrically fixedly connected to the inside of two second mounting holes 9. A rotating block 11 is rotatably connected between two second rotating connectors 10 located in the same second mounting hole 9. A screw rod 12 is fixedly connected to one end of each of the two rotating blocks 11 that is close to each other. A bidirectional internal thread tube 13 is threadedly connected to the outside of the two screw rods 12.
[0020] When this application embodiment is used: During pipe installation, the matching bolts are passed through the first mounting hole 2 and fixed in the appropriate position. The positioning bolt 15 is then removed from the angle positioning hole 4. The rotating cross 6 is then turned, causing the first rotating connector 5 to rotate inside the rotating connecting groove 14. After rotating to the appropriate position, the positioning bolt 15 rotates and enters the angle positioning hole 4, thus fixing the rotating cross 6. During this process, the universal connector 7 rotates accordingly. Then, the bidirectional internal threaded pipe 13 is screwed to engage with the two engagement screws 12, causing the two engagement screws 12 to move closer or further apart. This simultaneously drives the rotating block 11 to move closer together, allowing the angle adjustment plate to adjust. Rotate the pipe on the universal connector 7 to adjust the angle. Then, put the two sliding brackets 17 on the guide rail 16, place both ends of the pipe inside the fixed arc frame 18, and then place the movable locking top cover 22 on the top of the fixed arc frame 18 so that the movable locking top cover 22 and the connecting horizontal plate 19 on the fixed arc frame 18 correspond. Screw the positioning screw 20 into the connecting horizontal plate 19, place the sealing gasket 26 between the two pipes, and then use the two-way fastening screw 24 to dock and position the movable locking top cover 22 and the fixed arc frame 18. Then continue to screw the positioning screw 20 into the longitudinal positioning hole 21 to complete the fixation.
