The quality of the connection directly affects the sealing performance, durability and overall function of the water supply and drainage system. In terms of sealing performance, the existing pipe connection devices for water supply and drainage projects commonly use threaded connections, which lack an integrated sealing and blocking structure. After long-term use, they are easily affected by factors such as water flow impact and vibration, which can lead to sealing failure at the connection and cause water leakage. It is also inconvenient to improve the durability of the sealing structure. Utility Model Content

[0026] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0027] Example 1: As Figure 1 and 2 ,include:

[0028] A water supply and drainage pipe 100 is provided at the end of the water supply and drainage pipe 100, and the joint of two water supply and drainage pipes 100 is fixedly connected by the flange 110.

[0029] The docking assembly includes a sealed docking cylinder 200. The outer walls of both ends of the sealed docking cylinder 200 are provided with inner insertion tubes 220, which are inserted and sealed to the inner wall of the docking end of the water supply and drainage pipe 100.

[0030] The specific application scenario of this embodiment is as follows: When connecting the water supply and drainage pipes 100, first align the ends of the two water supply and drainage pipes 100, and perform preliminary positioning using the flange 110. The flange 110 provides a fixed foundation for the docking of the water supply and drainage pipes 100, enabling the two pipes to maintain a relatively stable positional relationship. Subsequently, insert the inner tubes 220 at both ends of the sealing docking cylinder 200 into the inner wall of the docking end of the water supply and drainage pipe 100. The insertion of the inner tubes 220 into the inner wall of the water supply and drainage pipe 100, through the tight fit between the two, forms the first line of sealing defense, which can effectively prevent water from leaking from the gap at the pipe docking point. In the actual water supply and drainage process, when the water flows inside the water supply and drainage pipe 100, due to the sealed connection between the inner tubes 220 and the inner wall of the water supply and drainage pipe 100, the water can only flow inside the pipe and will not flow out from the docking point, thereby realizing the basic sealing function of the pipe connection and ensuring the normal operation of the water supply and drainage system.

[0031] Example 2: Figures 3-5 The flange 110 is welded to the outer wall of the end of the water supply and drainage pipe 100. The inner wall of the flange 110 has evenly spaced insertion holes 120. The outer wall of the flange 110 on the side away from the water supply and drainage pipe 100 has an annular groove 130. Sealing rings 221, made of rubber, are evenly fixedly installed on the outer wall of the inner insertion pipe 220. The deformation of the outer wall of the sealing ring 221 seals and fills the gap between the outer wall of the inner insertion pipe 220 and the inner wall of the water supply and drainage pipe 100. The annular structure in the middle of the sealing coupling cylinder 200 matches the diameter of the flange 110. Embedded sealing rings 210 are fixedly installed on both outer walls of the annular structure. The sealing ring 210 is inserted into the inner wall of the annular groove 130 for sealing connection. Rubber plug tubes 230 are uniformly fixedly installed on the inner wall of the annular structure. The rubber plug tubes 230 are distributed in corresponding positions to the plug holes 120. The rubber plug tubes 230 are inserted into the inner wall of the plug holes 120 for sealing connection. The end of the rubber plug tube 230 is flush with the outer wall of the plug hole 120. A bolt hole 231 is opened on the inner wall of the center of the inner wall of the rubber plug tube 230. A screw 240 is inserted into the inner wall of the bolt hole 231. Nuts 250 are threaded on the outer walls of both ends of the screw 240 for sealing and fixing the two water supply and drainage pipes 100 and the sealing docking cylinder 200.

[0032] The specific application scenario of this embodiment is as follows: During the connection process, the flange 110 is first welded to the outer wall of the end of the water supply and drainage pipe 100. The insertion hole 120 on its inner wall and the annular groove 130 on its outer wall provide a precise fitting structure for the subsequent installation of the sealing docking cylinder 200. The embedded sealing rings 210 on both sides of the annular structure in the middle of the sealing docking cylinder 200 are inserted into the annular groove 130 of the flange 110 to form an annular sealing structure, which further enhances the sealing performance at the joint and effectively prevents water from seeping out from the connection between the flange 110 and the sealing docking cylinder 200. At the same time, the sealing rings 221 on the outer wall of the inner insertion tubes 220 at both ends of the sealing docking cylinder 200 deform due to compression when inserted into the inner wall of the water supply and drainage pipe 100, tightly filling the gap between the outer wall of the inner insertion tube 220 and the inner wall of the water supply and drainage pipe 100, achieving a more reliable sealing effect and ensuring that water will not seep out from the inner wall. Leakage occurs in the joint between the insertion pipe 220 and the water supply and drainage pipe 100. In addition, the rubber insertion pipe 230 on the inner wall of the annular structure of the sealing connection cylinder 200 is inserted into the insertion hole 120 on the inner wall of the flange 110. The bolt hole 231 on the inner wall of the rubber insertion pipe 230 is inserted into the screw 240 and tightened by the nuts 250 at both ends. This structure not only tightly fixes the two water supply and drainage pipes 100 and the sealing connection cylinder 200 together, but also generates a certain pressure on each component during the tightening of the nuts 250, further promoting the tight fit between the sealing ring 221 and the embedded sealing ring 210, enhancing the sealing performance. During the water supply and drainage process, the pressure generated by the water flow in the pipe is borne by these multiple sealing and fastening structures, ensuring that the water flow always flows in the sealed pipe and there is no leakage, thus ensuring the stability and reliability of the water supply and drainage pipeline connection.

[0033] The working principle of this utility model is as follows: When used by those skilled in the art, the water supply and drainage pipeline connection device works by first aligning the ends of the two water supply and drainage pipes 100 and initially positioning them using the flange 110. Then, the inner tubes 220 at both ends of the sealing docking cylinder 200 are inserted into the inner wall of the water supply and drainage pipes 100. The sealing ring 221 on the outer wall of the inner tube 220 is compressed and deformed, filling the gaps and forming a seal.

[0034] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
