Description

Technical Field

[0001] This utility model relates to the field of drainage pipe technology, and in particular to a drainage pipe connection joint with good leak-proof effect. Background Technology

[0002] Drainage pipelines refer to the system of pipes and their ancillary facilities that collect and discharge sewage, wastewater, and rainwater. This includes main pipes, branch pipes, and pipes leading to treatment plants. Regardless of whether they are built on streets or anywhere else, any pipe that serves a drainage function should be counted as a drainage pipeline. The length of a drainage pipeline refers to the sum of the lengths of all main drainage pipes, branch pipes, inspection wells, and connecting well inlets and outlets. When calculating, it should be calculated as a single pipe. That is, if there are two or more drainage pipelines running side by side on the same street, the lengths of each drainage pipeline should be added together.

[0003] Drainage pipe connectors are an indispensable component in building and municipal engineering. Their function is to tightly connect various parts of the drainage pipe system to ensure smooth water flow and prevent leakage. The installation process of traditional connectors is cumbersome, requiring precise alignment and fixing, which not only increases the difficulty of construction but also reduces construction efficiency. To address these issues, we propose a drainage pipe connector with good leak-proof performance. Utility Model Content

A first positioning plate is fixedly connected to the outer surface of the first pipe, and a second positioning plate is fixedly connected to the outer surface of the second pipe. Both the right side of the second positioning plate and the right side of the first positioning plate have annularly arranged connecting holes. A locking pin is inserted into the inner ring of each set of connecting holes. A locking cap is threaded onto the outer surface of each locking pin. An annularly arranged positioning rod is fixedly connected to the right side of the second positioning plate. An annularly arranged positioning hole is formed on the right side of the first positioning plate. The right end of each positioning rod passes through a positioning hole and extends to the right side of the first positioning plate, with the positioning rod and positioning hole being compatible. The right end of the second pipe extends into the interior of the first pipe. Multiple semi-circular sealing grooves are formed on the inner wall of the first pipe and the outer surface of the second pipe. A sealing ring is engaged with the inner wall of each semi-circular sealing groove.

[0007] In a further embodiment, two snap-fit ​​recesses are fixedly connected to the upper surface of the support base, and the inner sidewalls of the two snap-fit ​​recesses are respectively snapped into the outer surface of the first pipe and the outer surface of the second pipe.

[0008] In a further embodiment, the support base has two sets of mounting holes on its front side, and each mounting hole has a threaded inner ring.

[0009] In a further embodiment, reinforcing rings are fixedly connected to the outer surfaces of the first pipe and the second pipe, and the sides of the two reinforcing rings that are close to each other are fixedly connected to the sides of the first positioning plate and the second positioning plate that are far apart from each other.

[0010] In a further embodiment, a ring of limiting blocks is fixedly connected to the right side of the second positioning disk, and the right end of each limiting block is in contact with the left side of the first positioning disk. The sides of the two sets of limiting blocks that are close to each other are in contact with the outer surface of the first pipe.

[0011] In a further embodiment, an annular sealing groove is provided at the right end of the second pipe, and a sealing gasket is provided inside the first pipe, and the sealing gasket is engaged with the annular sealing groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This device, through the cooperation of the support base and mounting holes, can securely install the drain pipe connection joint in the designated position. By connecting the first and second positioning plates and utilizing the cooperation of the connection holes, locking pins, locking caps, positioning rods, and positioning holes, the two pipes are accurately positioned and firmly fixed. The locking pins and locking caps can lock the pipes. At the same time, the use of the sealing gasket, annular sealing groove, sealing ring, and semi-circular sealing groove can seal the connection gap between the first and second pipes, thereby effectively preventing water leakage at the connection gap between the pipes.
