Description

Technical Field

[0001] This utility model relates to the field of water supply and drainage pipeline technology, and in particular to a connection structure for water supply and drainage pipelines in prefabricated buildings. Background Technology

[0002] The water supply and drainage pipeline system plays a core role in the allocation of water resources within a building. Its functions include a forward distribution system responsible for supplying water for production and circulating hot and cold water for domestic use; and a reverse collection system responsible for wastewater discharge and pre-treatment diversion. During the system construction process, the topological connection of drainage pipelines integrates the fluid channels of multiple pipeline nodes through specialized connection devices.

[0003] Chinese Patent No. CN222760466U discloses a prefabricated building water supply and drainage pipe connection structure, including a first water supply and drainage pipe and a second water supply and drainage pipe. Both ends of the first water supply and drainage pipe are fixedly equipped with first connecting rings, and both ends of the second water supply and drainage pipe are fixedly equipped with second connecting rings. An installation plate is provided on the outside of the connection end of the first and second water supply and drainage pipes. When installing the vertically arranged first and second water supply and drainage pipes, the first connecting rings fixedly installed at both ends of the first water supply and drainage pipe can be pre-installed and fixed between the left limiting block and the left sealing ring, respectively. Then, the user can pre-install the second water supply and drainage pipe in the same way. The pre-installation and fixation of the first and second water supply and drainage pipes through the structure on the installation plate avoids the influence of the self-weight of the first and second water supply and drainage pipes on the installation process.

[0004] However, the above technical solution has the following shortcomings: when the connection structure is used to fix and install water supply and drainage pipes, it cannot adjust the fixing effect according to the size deviation of the water supply and drainage pipes, which can easily lead to loose clamping and thus affect the normal use of water supply and drainage pipes. Utility Model Content

[0005] The purpose of this utility model is to address the problems existing in the background technology by proposing a prefabricated building water supply and drainage pipe connection structure, which can not only play a good and stable fixing role for the connection parts of water supply and drainage pipes, but also improve the applicability of the connection structure.

[0006] The technical solution of this utility model is a prefabricated building water supply and drainage pipe connection structure, including a second rotating frame and a fastening assembly; the second rotating frame is provided with a connecting block and a second platform, the connecting block is rotatably connected to a first rotating frame, and the first rotating frame is provided with a first platform; the fastening assembly includes five first fixing plates provided on the first rotating frame and the second rotating frame, a rotating shaft threadedly connected to the first fixing plate, two guide rods slidably connected to the first fixing plate, a pressure plate provided on the guide rods, a fixing ring coaxially provided on the rotating shaft, a handle provided at the end of the rotating shaft away from the fixing ring, and a first elastic anti-slip pad provided on the pressure plate; the rotating shaft is provided with a threaded part, the threaded part is threadedly connected to the first fixing plate, and the fixing ring is rotatably provided inside the pressure plate.

[0007] Preferably, a retaining ring is provided on the guide rod.

[0008] Preferably, the first rotating frame and the second rotating frame are provided with five pre-fixing components. The pre-fixing components include a second fixing plate, three springs equidistantly distributed on the second fixing plate, and a top plate disposed on the springs.

[0009] Preferably, a second elastic anti-slip pad is provided on the top plate.

[0010] Preferably, three stabilizing rods are slidably connected to the second fixed plate, with one end of each stabilizing rod disposed on the top plate.

[0011] Preferably, a convex ring is coaxially provided on the stabilizer bar, and the convex ring is slidably disposed inside the second fixed plate.

[0012] Preferably, two bolts are provided through the first platform and the second platform, and nuts are threaded onto the bolts. The bolts and nuts abut against the first platform and the second platform, respectively.

[0013] Compared with the prior art, the present invention has the following beneficial technical effects:

[0014] This utility model not only improves the stability of the connection between water supply and drainage pipes by setting the pre-fixing component, but also facilitates the subsequent fixing operation. The fastening component can not only play a good role in fixing the water supply and drainage pipes, but also realize the adjustment of the position of the pressure plate 7 according to the size deviation of the water supply and drainage pipes, which improves the practicality of the connection structure and is simple and convenient to operate.

[0020] Example 1

[0021] like Figures 1-4 As shown in the figure, the prefabricated building water supply and drainage pipe connection structure proposed in this embodiment includes a second rotating frame 2 and a fastening assembly; the second rotating frame 2 is provided with a connecting block 3 and a second platform 14, the connecting block 3 is rotatably connected to a first rotating frame 1, and the first rotating frame 1 is provided with a first platform 13.

[0022] The fastening assembly includes five first fixing plates 4 mounted on the first rotating frame 1 and the second rotating frame 2, a rotating shaft 5 threadedly connected to the first fixing plate 4, two guide rods 6 slidably connected to the first fixing plate 4, a pressure plate 7 mounted on the guide rods 6, a fixing ring 8 coaxially mounted on the rotating shaft 5, a handle 11 mounted on the end of the rotating shaft 5 away from the fixing ring 8, and a first elastic anti-slip pad 9 mounted on the pressure plate 7; the rotating shaft 5 is provided with a threaded part 12, which is threadedly connected to the first fixing plate 4, the fixing ring 8 is rotatably mounted inside the pressure plate 7, and the guide rod 6 is provided with a retaining ring 10.

[0023] In this embodiment, when connecting, the ports of the two water supply and drainage pipes are first inserted into each other, and a sealing kit is set at the joint gap. Then, the openings of the first rotating frame 1 and the second rotating frame 2 wrap around the outer surfaces of the water supply and drainage pipes on both sides of the joint. The first rotating frame 1 and the second rotating frame 2 are then closed by the connecting block 3. Then, the rotating shaft 5 is rotated by the handle 11 so that the threaded part 12 of the rotating shaft 5 is screwed into the first fixing plate 4. Under the guidance of the guide rod 6 and the pushing action of the fixing ring 8 on the pressure plate 7, the rotating shaft 5 drives the pressure plate 7 to move towards the water supply and drainage pipe until the pressure plate 7 is pressed tightly against the outer wall of the water supply and drainage pipe. At the same time, the first elastic anti-slip pad 9 is provided to improve the fastening effect of the pressure plate 7 without abrading the pipe. Furthermore, the movement adjustment of the rotating shaft 5 and the elastic compensation of the first elastic anti-slip pad 9 allow the position of the pressure plate 7 to be adjusted according to the size deviation of the water supply and drainage pipe, which improves the practicality of the connection structure and makes the operation simple and convenient.

[0024] It should be noted that the threaded part 12 adopts a thread with a small pitch, a large thread angle and a large coefficient of friction to achieve self-locking of the shaft 5 and avoid the problem of displacement after long-term use.

[0025] Example 2

[0026] like Figure 3 As shown in the figure, the prefabricated building water supply and drainage pipe connection structure proposed in this embodiment, compared with the first embodiment, has five pre-fixing components on the first rotating frame 1 and the second rotating frame 2. The pre-fixing components include a second fixing plate 15, three springs 16 equidistantly on the second fixing plate 15, and a top plate 17 on the springs 16. A second elastic anti-slip pad 18 is provided on the top plate 17.

[0027] Three stabilizing rods 19 are slidably connected to the second fixed plate 15. One end of the stabilizing rod 19 is set on the top plate 17. A convex ring 20 is coaxially set on the stabilizing rod 19 and is slidably set inside the second fixed plate 15.

[0028] In this embodiment, during the closing process of the first rotating frame 1 and the second rotating frame 2, the top plate 17 around the perimeter will abut against the connection of the two water supply and drainage pipes and their surrounding outer peripheral surfaces in advance. The abutment action between the top plate 17 and the water supply and drainage pipes will gradually compress the spring 16. The elastic force of the spring 16 when it is compressed will play a pre-fixing role, which not only improves the stability of the connection, but also helps the subsequent operation of the fixing components. At the same time, the setting of the stabilizing rod 19 plays a guiding role in the extension and retraction of the spring 16, preventing the spring 16 from being completely twisted. The convex ring 20 is used to limit the extension and retraction of the spring 16 and control the spring 16 to always be in a compressed state.

[0029] Example 3

[0030] like Figure 4 As shown in the figure, the prefabricated building water supply and drainage pipe connection structure proposed in this embodiment has two bolts 21 through the first platform 13 and the second platform 14, and nuts 22 are threadedly connected to the bolts 21. The bolts 21 and nuts 22 abut against the first platform 13 and the second platform 14 respectively.

[0031] In this embodiment, after the first platform 13 and the second platform 14 are closed together with the first rotating frame 1 and the second rotating frame 2, the bolt 21 is passed through the first platform 13 and the second platform 14, and then the nut 22 is screwed onto the bolt 21.

[0032] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
