Description

Technical Field

[0001] The utility model relates to the technical field of pipeline connection, in particular to a municipal drainage pipeline quick repair connector. Background Art

[0002] Pipe connection refers to the process of connecting two or more sections of pipes together in a specific way to achieve fluid transportation or sealing. When the municipal drainage pipes encounter pipe ruptures and interface leakage, in order to ensure the restoration of the airtightness of the pipes, corresponding emergency repair connectors are needed.

[0003] The existing utility model with authorization announcement number CN221034439U discloses a water supply and drainage pipe connector. By setting a rubber pad and with the help of the extrusion plate, the purpose of limiting and clamping the pipes connected on both sides of the pipe can be achieved. By setting bolts and with the help of the mounting holes of the connecting base and the connector, the function of fixing the pipe by the connecting base and the connector can be achieved by tightening the bolts. By setting a screw rod and rotating the screw rod with the help of a turntable, the extrusion plate is driven to extrude downward, which can achieve the purpose of further stabilizing the connected pipes. The motor drives the rotating rod to rotate, and with the help of the stirring blades on the surface of the rotating rod, the debris in the pipe can be crushed to prevent blockage in the pipe.

[0004] Although the above technical solution can limit and clamp the pipes connected on both sides of the pipeline, and can crush the debris in the pipeline to prevent blockage in the pipeline, the above technical solution requires the use of a bolt structure for docking and fixing the connection structure, which requires the use of external tools. There is a lack of a convenient connection structure that is easy and quick to disassemble and assemble, resulting in poor efficiency in pipeline connection or emergency repair.

[0005] Therefore, those skilled in the art provide a municipal drainage pipe quick repair connector to solve the problems raised in the above background technology. Utility Model Content

[0011] As a further solution of the present invention: the inner wall of each of the first arc-shaped clips is fixedly connected to a first anti-slip pad, and the inner wall of each of the first anti-slip pads is in contact with the outer surface of the first sealing pad and the outer surface of the second sealing pad respectively.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

After the second arc clamp rotates around the first support rod, it can cooperate with the first arc clamp to clamp the first sealing gasket and the second sealing gasket to a limit position. After the rotating plate rotates around the second support rod and the limit plate slides along the outer surface of the guide rod, the limit plate can be stuck into the interior of the first arc clamp. In addition, the return spring can strongly return the limit plate, so that the first sealing gasket and the second sealing gasket can seal and tightly wrap the two pipe bodies very conveniently, and the removal of the first sealing gasket and the second sealing gasket only requires pulling the limit plate and rotating the rotating plate, which increases the repair speed and emergency repair efficiency of the broken pipe body and avoids the problem of poor pipeline connection or emergency repair efficiency due to the lack of a convenient connection structure that is easy to disassemble and assemble.
