[0026] Exemplary embodiments of the present disclosure will be described in greater detail below with reference to the accompanying drawings.

[0027] Embodiment

[0028] As mentioned in the background, in the water supply and drainage engineering, whether in the normal laying process of the pipeline or in the temporary pipeline laying, the branch pipe is needed for the diversion of water source, and the three-way pipe is mostly used for the branch pipe. However, the inventor finds that the existing three-way pipe has many defects in use, for example, the size of the connected pipeline needs to be strictly controlled, and if the pipeline is too long or too short, it needs to be shortened or lengthened to complete the connection with the three-way pipe. Therefore, the inventor innovates and improves, and designs a new type of branch pipe, which will be described in detail below in combination with the drawings.

[0029] The embodiment provides a branch pipe for water supply and drainage, referring to Figure 1 and Figure 3 , comprising a main pipe part 1, and the main pipe part 1 is a three-way structure, comprising two communicating horizontal ends 110 and a vertical end 120 vertically communicated with the two, the main pipe part 1 is a normal three-way joint structure, the horizontal end 110 and the vertical end 120 are used for water inlet or water outlet, and the pipelines connected with the two are communicated to realize the water flow guiding function.

[0030] In this embodiment, as one of the main design points of the scheme, two horizontal ends 110 are respectively provided with mounting pipes 2, the mounting pipes 2 and the horizontal ends 110 are connected through connecting pipes 3, and the connecting pipes 3 are telescopic. Through the telescopic connecting pipes 3, the distance between the mounting pipes 2 and the main pipe part 1 can be adjusted, so that when the branch connecting pipe is installed with the pipeline, whether the pipeline is too long or not enough to be connected with the branch pipeline, the telescopic connecting pipes 3 can be adjusted to compensate, so that the branch connecting pipe can be connected and fixed with the pipeline.

[0031] In addition, the bottom of the vertical end 120 is also connected with the mounting pipe 2, and the mounting pipe 2 and the vertical end 120 are connected through the telescopic connecting pipe 3. The connecting mode of the vertical end 120 and the mounting pipe 2 is consistent with that of the horizontal end 110, which further expands the adjustment range of the branch connecting pipe and can adapt to more different actual installation conditions.

[0032] On the basis of the above structure, the connecting pipe 3 is a corrugated pipe, and the two ends are respectively connected and fixed with the main pipe part 1 and the mounting pipe 2 through flanges. The corrugated pipe is the preferred scheme adopted by the inventor, and is not a limitation on the material and type of the connecting pipe 3. It can be telescopic to realize the extension and retraction of the mounting pipe 2.

[0033] In this embodiment, after the length of the mounting pipe 2 is adjusted, it is secondarily fixed with the main pipe part 1. The horizontal end 110 close to the mounting pipe 2 is connected through a connecting piece 4. The connecting piece 4 can connect the horizontal end 110 and the mounting pipe 2. Similarly, the vertical end 120 and the mounting pipe 2 are also connected through the connecting piece 4, and the connecting mode is consistent. A strip-shaped slot 5 is longitudinally and centrally provided in the connecting piece 4. The strip-shaped slot 5 is horizontally provided in the scheme, and the two ends do not penetrate the connecting piece 4. In combination with Figure 2 The horizontal end 110 and the side surface of the mounting pipe 2 are both provided with mounting holes 6. When the connecting piece 4 is fixed, the mounting holes 6 are aligned with the strip-shaped slot 5. The mounting holes 6 are provided with limiting columns 7, and the limiting columns 7 penetrate the strip-shaped slot 5. The limiting columns 7 can limit the connecting piece 4, complete the fixation, and the mounting holes 6 are provided with internal threads. The limiting columns 7 are provided with external threads, which can be matched with the internal threads of the mounting holes 6. Through the matching of the external threads of the limiting columns 7 and the internal threads of the mounting holes 6, the stability of the fixation of the connecting piece 4 is improved. The width of the mounting slot is smaller than the size of the head of the fastening bolt, which can form abutment with the connecting piece 4 after the fastening bolt is tightened to complete the fixation.

[0034] It needs to be explained that the connecting piece 4 is provided at least two groups around the outer edge surface of the mounting pipe 2, and at least two mounting holes 6 are provided on the side surface of the mounting pipe 2. The two groups of connecting pieces 4 are oppositely arranged on both sides of the mounting pipe 2, and the fixing strength and balance of the mounting pipe 2 and the main pipe part 1 can be improved by the two groups of oppositely arranged connecting pieces 4.

[0035] On the basis of the above structure, a plurality of arc-shaped grooves 8 are arranged in the length direction of the strip-shaped groove 5, and the arc-shaped grooves 8 can accommodate the outer end surface of the fastening bolt. The spacing size of the arc-shaped grooves 8 is uniform, and by arranging the arc-shaped grooves 8, the arc-shaped grooves 8 can be matched with the end surface of the fastening bolt after the fastening bolt is inserted into the mounting hole 6, thereby forming a limit between the two, and the stability of the connecting piece 4 is improved.

[0036] In this embodiment, in combination with Figure 4 , the mounting pipe 2 gradually increases in outer diameter and inner diameter from the direction towards the main pipe part 1, that is, the diameter of one end of the mounting pipe 2 connected to the pipe 3 is larger, which facilitates the insertion of the pipe, in addition, the mounting pipe 2 is made of elastic material, and a plurality of grooves 10 are arranged on the outer edge surface of the end of the mounting pipe 2 away from the main pipe part 1. In this scheme, the grooves 10 are arranged in an array of 4 with respect to the mounting pipe 2, so that the mounting pipe 2 can be pushed outward when the pipe is inserted, which facilitates the insertion, and the length of the groove 10 is not more than 1 / 2 of the length of the end surface of the mounting pipe 2. The size of the groove 10 can be prevented from being too large, so that the end of the pipe can enter the position of the mounting pipe 2 far away from the groove 10 after the pipe is inserted into the mounting pipe 2, and water seepage at the groove 10 is avoided when the pipe is inserted into the mounting pipe 2, which improves the sealing of the connection between the pipe and the mounting pipe 2. The outer edge surface of the mounting pipe 2 is provided with external threads, and a locking nut 9 is connected through the external threads. After the pipe is inserted into the mounting pipe 2, the locking nut 9 is rotated and moved away from the mounting pipe 2 to press the mounting pipe 2 and the pipe to be laid, which improves the stability of the connection between the pipe and the mounting pipe.
