[0043] like Figures 1-4 As shown, this embodiment provides a seepage prevention device for water supply and drainage pipes in building engineering, including:

[0044] First drainage pipe 100;

[0045] The first drain pipe 100 is disposed on one side of the connecting assembly 200;

[0046] The second drain pipe 110 is located on the other side of the connecting assembly 200;

[0047] The fixing mechanism 300 is positioned above the connecting component 200;

[0048] The connection component 200 includes:

[0049] The outer casing 210 has fixing blocks 220 at both ends. The first drain pipe 100 and the second drain pipe 110 pass through the fixing blocks 220 and are connected to the inside of the outer casing 210.

[0050] A rubber tube 230 is disposed inside the housing 210 and contacts the inner wall of the housing 210, and the first drain pipe 100 and the second drain pipe 110 are connected inside the rubber tube 230.

[0051] An annular groove 240 is formed on the outer wall of the rubber tube 230 and the inner wall of the outer shell 210, and multiple annular grooves 240 are provided.

[0052] An operating hole 250 is provided through the housing 210, and the position of the operating hole 250 corresponds to that of the annular groove 240;

[0053] A steel wire 260 is disposed inside the annular groove 240, and both ends of the steel wire 260 extend through the operating hole 250 to the outside of the housing 210.

[0054] In this technical solution, to reduce loosening at the connection between the first drain pipe 100 and the second drain pipe 110, a connecting component 200 is provided on the outer side where the first drain pipe 100 and the second drain pipe 110 connect. The outer shell 210 of the connecting component 200 is located on the outer side of the first drain pipe 100 and the second drain pipe 110. Fixing blocks 220 are fixedly installed on both sides of the outer shell 210. The first drain pipe 100 and the second drain pipe 110 are connected inside the outer shell 210 by passing through the fixing blocks 220 on both sides. The fixing blocks 220 are made of rubber, which can reduce the vibration received by the first drain pipe 100 and the second drain pipe 110 during drainage and reduce the risk of leakage at the connection between the two drain pipes. In addition, a rubber tube 230 is provided inside the outer shell 210. The outer wall of the rubber tube 230 is fitted with the inner wall of the outer shell 210, and the first drain pipe 100 and the second drain pipe 110 are inside the rubber tube 230. To facilitate connection, an annular groove 240 is formed at the contact point between the outer wall of the rubber tube 230 and the inner wall of the outer casing 210. The annular groove 240 is formed on both sides of the connection point of the two drain pipes. A through operating hole 250 is formed on the outer casing 210 at the corresponding position of the annular groove 240. A steel wire 260 is placed inside the annular groove 240, with both ends of the steel wire 260 extending through the operating hole 250 to the outside of the outer casing 210. After the first drain pipe 100 and the second drain pipe 110 are connected inside the rubber tube 230, the two ends of the steel wire 260 are wrapped around it, thereby sealing the rubber tube 230 with the two drain pipes. This reduces leakage at the connection point and also reduces vibration of the two drain pipes, thus reducing the risk of gaps at the connection point and further reducing the risk of leakage between the first drain pipe 100 and the second drain pipe 110.

[0055] This embodiment provides a seepage prevention device for water supply and drainage pipes in building engineering. In addition to the technical solutions of the above embodiments, it also has the following technical features.

[0056] like Figures 1-4 As shown, in this embodiment, the fixing mechanism 300 includes:

[0057] The mounting slot 310 is formed through the center of the housing 210;

[0058] The rotating shaft 320 has its two ends fixedly connected to the housing 210 on both sides of the mounting groove 310;

[0059] The first connecting plate 330 is rotatably mounted on the rotating shaft 320 at one end;

[0060] The second connecting plate 340 is rotatably mounted on the rotating shaft 320 at one end;

[0061] The upright plate 350 is fixedly disposed at the end of the first connecting plate 330 and the second connecting plate 340 away from the rotation axis 320;

[0062] The limiting mechanism 360 is fixedly mounted on the outer casing 210.

[0063] In this technical solution, to ensure the stability of the connection between the first drain pipe 100 and the second drain pipe 110, a through mounting groove 310 is provided in the center of the outer casing 210. A rotating shaft 320 is fixed inside the mounting groove 310, and both ends of the rotating shaft 320 are fixedly connected to the outer casing 210 on both sides of the mounting groove 310. A rotatable first connecting plate 330 and a second connecting plate 340 are respectively mounted on the rotating shaft 320. One end of the first connecting plate 330 and the second connecting plate 340 are respectively mounted on the rotating shaft 320, and the first connecting plate 330 and the second connecting plate 340 are located away from the rotating shaft 320. One end of each is fixed with a vertical plate 350. A limiting mechanism 360 is provided on the outer shell 210. The limiting mechanism 360 can limit the vertical plate 350, thereby ensuring that the first connecting plate 330 and the second connecting plate 340 rotate at a certain angle on the rotating shaft 320. Then, it is fixed, thereby fixing the area between the first connecting plate 330 and the second connecting plate 340. This allows the first drain pipe 100 and the second drain pipe 110 to be fixed inside the outer shell 210, reinforcing the connection between the two drain pipes and reducing the shaking at the connection between the two drain pipes, further reducing the possibility of leakage from the two drain pipes.

[0064] This embodiment provides a seepage prevention device for water supply and drainage pipes in building engineering. In addition to the technical solutions of the above embodiments, it also has the following technical features.

[0065] like Figures 1-4 As shown, in this embodiment, the limiting mechanism 360 includes:

[0066] Mounting bracket 361 is fixedly mounted on the surface of housing 210;

[0067] The receiving plate 362 is fixedly installed on one side of the mounting base 361;

[0068] A sliding groove 363 is formed on the upper surface of the mounting base 361;

[0069] Slider 364 is slidably positioned inside sliding groove 363;

[0070] The U-shaped frame 365 is horizontally fixed above the slider 364, and the upright plate 350 is disposed between the U-shaped frames 365.

[0071] A threaded hole 366 is formed through the U-shaped frame 365 and the receiving plate 362;

[0072] Bolt 367 is installed inside threaded hole 366.

[0073] In this technical solution, a limiting mechanism 360 is provided to fix the first connecting plate 330 and the second connecting plate 340. The mounting base 361 of the limiting mechanism 360 is fixedly installed on the surface of the housing 210 and is located on the side of the housing 210 away from the rotation axis 320. A receiving plate 362 is fixedly installed on one side of the mounting base 361. A sliding groove 363 is provided on the upper surface of the mounting base 361. A sliding slider 364 is provided inside the sliding groove 363. A U-shaped frame 365 is fixedly installed on the upper surface of the slider 364, with the opening of the U-shaped frame 365 facing the upright plate. A vertical plate 350 is positioned on one side of a U-shaped frame 365, with a through threaded hole 366 on the U-shaped frame 365 and a threaded hole 366 of the same height on the receiving plate 362. A bolt 367 is installed inside the threaded hole 366, allowing the position of the U-shaped frame 365 in the sliding groove 363 direction to be changed. This causes the vertical plate 350 to move with the U-shaped frame 365, thereby changing the fixed area formed between the first connecting plate 330 and the second connecting plate 340, thus limiting the movement of the two drain pipes.

[0074] This embodiment provides a seepage prevention device for water supply and drainage pipes in building engineering. In addition to the technical solutions of the above embodiments, it also has the following technical features.

[0075] like Figures 1-4 As shown, in this embodiment, the distance between the inner walls of the U-shaped frame 365 is equal to the width of the upright plate 350, and the upright plate 350 slides against the inner wall of the U-shaped frame 365.

[0076] In this technical solution, to enable the U-shaped frame 365 to limit the upright plate 350, the width of the internal opening of the U-shaped frame 365 is set to be equal to the width of the upright plate 350, and the height of the U-shaped frame 365 is greater than the height of the upright plate 350. The outer wall of the upright plate 350 slides against the inner wall of the U-shaped frame 365. Thus, when the position of the U-shaped frame 365 is changed horizontally, the upright plate 350 can change its height vertically within the U-shaped frame 365. This allows the upright plate to remain in place while the length and shape of the first connecting plate 330 and the second connecting plate 340 remain unchanged. As the horizontal position of plate 350 changes with the U-shaped frame 365, the vertical position of plate 350 inside the U-shaped frame 365 also changes. The longer U-shaped frame 365 can limit the vertical position of plate 350. After the first connecting plate 330 and the second connecting plate 340 abut against the outer periphery of the two drain pipes, bolt 367 can stabilize the position of U-shaped frame 365, thereby stabilizing the position of plate 350. Ultimately, the position of the connecting plate is stabilized, reducing the shaking at the connection of the two drain pipes and reducing the occurrence of leakage.

[0077] This embodiment provides a seepage prevention device for water supply and drainage pipes in building engineering. In addition to the technical solutions of the above embodiments, it also has the following technical features.

[0078] like Figures 1-4 As shown, in this embodiment, there are two limiting mechanisms 360. The two limiting mechanisms 360 are disposed on the outer shell 210 on both sides of the mounting groove 310, and the two limiting mechanisms 360 respectively limit the first connecting plate 330 and the second connecting plate 340.

[0079] In this technical solution, to limit the movement of drain pipes of different diameters, the first connecting plate 330 and the second connecting plate 340 are designed to be non-intersecting, with one side of the two connecting plates close to each other and sliding together. Therefore, the two connecting plates rotate at different angles on the rotating shaft 320, and the fixed area formed between the two connecting plates can be increased or decreased. Thus, the first connecting plate 330 and the second connecting plate 340 can limit drain pipes of different diameters, increasing practicality. Furthermore, before installing the two drain pipes, the two upright plates 350 are respectively installed inside the two U-shaped frames 365, and then... The two drain pipes are connected by inserting them into the housing 210 from the fixing block 220. Then, the first connecting plate 330 and the second connecting plate 340 are moved closer to the two drain pipes until the two connecting plates abut against the outer walls of the two drain pipes. Then, the U-shaped frame 365 is fixed in place, and the bolt 367 is rotated until the nut of the bolt 367 abuts against the receiving plate 362. At this point, the U-shaped frame 365 can be fixed on the mounting base 361, thereby stabilizing the position of the two connecting plates and thus stabilizing the position of the connection between the two drain pipes. This reduces the shaking of the two drain pipes and reduces the occurrence of leakage.

[0080] This embodiment provides a seepage prevention device for water supply and drainage pipes in building engineering. In addition to the technical solutions of the above embodiments, it also has the following technical features.

[0081] like Figures 1-4 As shown, in this embodiment, the first drain pipe 100 and the second drain pipe 110 are connected by a thread.

[0082] In this technical solution, in order to facilitate the connection between the first drain pipe 100 and the second drain pipe 110, an internal thread is provided on one side of the first drain pipe 100 and an external thread is provided on one side of the second drain pipe 110. In this way, the two drain pipes can be connected by turning the end of the second drain pipe 110 with the external thread into the end of the first drain pipe 100 with the internal thread. This connection is convenient for the operator.

[0083] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive.
