Description

Technical Field

[0001] The utility model relates to the technical field of assembled buildings, in particular to a water supply and drainage pipeline connection structure of an assembled building. Background Art

[0002] The main task of water supply and drainage pipes is to transmit water for building production, cold water for domestic use, hot water, and wastewater for treatment, etc. When connecting drainage pipes, connecting devices are required to connect two pipes or multiple groups of pipes together. After multiple water supply and drainage pipes are connected, they must be fixed to the outer wall surface or other installation locations of the prefabricated building through external fastening components to ensure a firm connection between the water supply and drainage pipes and the prefabricated building.

[0003] However, the existing water supply and drainage pipes are generally large in size. When installing vertical water supply and drainage pipes, the gravity of the pipes themselves will affect the connection process between the pipes. Usually, the pipes need to be supported before the connection ends of the two water supply and drainage pipes can be in contact. This makes the construction of water supply and drainage pipes difficult and requires a lot of manpower during the actual installation process. After connecting multiple water supply and drainage pipes, users also need to fix the pipes to the prefabricated building through external fastening components such as clamps, which prolongs the construction steps of the entire pipe installation. To this end, we propose a prefabricated building water supply and drainage pipe connection structure. Utility Model Content

[0004] The utility model mainly solves the technical problems existing in the above-mentioned prior art and provides a prefabricated building water supply and drainage pipe connection structure.

[0006] Preferably, the two ends of the left limit block are respectively fixedly installed with docking rods, and the docking rods are penetrated by a docking groove. The two ends of the left sealing ring are respectively fixedly installed with extension blocks, and the ends of the extension blocks are fixedly installed with clamping plates used in conjunction with the docking grooves.

[0007] Preferably, the outer walls at both ends of the left sealing ring are fixedly connected to the middle position of the docking rod, and the outer walls at both ends of the right sealing ring are fixedly connected to the middle position of the extension block.

[0008] Preferably, the two right limit blocks and the outer wall of the right sealing ring are fixedly connected with a connecting column, and the connecting column is arranged in the middle position between the two right limit blocks and the right sealing ring.

[0009] Preferably, a guide plate is provided inside the docking groove, and the guide plate is inclined, and one end of the guide plate is rotatably connected to one side edge of the docking groove.
