Description

Technical Field

[0001] The utility model relates to the technical field of leak-blocking devices, in particular to a quick leak-blocking device for municipal drainage pipes. Background Art

[0002] The leak plugger is a pipe leak plugger used to repair pipelines, also known as a plug-in joint. It has a simple structure and is easy to use. It can be widely used in water supply and drainage and various liquid, gas, and pressure pipelines to repair water and gas leakage accidents caused by sand holes, air holes, transverse and longitudinal fractures. It saves labor, time and money to use.

[0003] When using a leak plugger to repair a damaged pipe, the leak plugger is mainly used to replace the damaged section of the pipe to achieve the purpose of plugging the leak. However, the pipe and the leak plugger are fixed by the contact between the sealing ring on the leak plugger and the pipe. If the leak plugger loosens and shifts under the action of external force, it may cause the leak plugger to leak, affecting the normal use of the pipe. Utility Model Content

[0004] The utility model provides a municipal drainage pipe leakage quick plugging device to solve the problem that if the plugging device is loosened and shifted under the action of external force, it may cause water leakage from the plugging device and affect the normal use of the pipeline.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a municipal drainage pipe leakage quick plugging device, comprising two semicircular tubes, one side of the two semicircular tubes abutting each other, both sides of the semicircular tubes are fixedly connected with extension blocks, the inner walls of the two adjacent extension blocks are evenly inserted with three threaded pins, the outer surfaces of the threaded pins are provided with nuts, the outer surfaces of the threaded pins are threadedly inserted into the inner walls of the nuts, one side of the nut abuts against one side of one of the extension blocks, the edge of the inner wall of the semicircular tube is fixedly connected with a sealing ring, and auxiliary devices are provided on both sides of the semicircular tube, the auxiliary device comprises two L-shaped plates, one end of the two L-shaped plates are fixedly connected to the two ends of the semicircular tube respectively, the inner wall of the L-shaped plate is threadedly connected with a threaded rod, one end of the threaded rod is rotatably connected with a clamping plate, and the outer surfaces of the two semicircular tubes are provided with reinforcement devices.

[0006] The effect achieved by the above components is: by arranging clamps at both ends of the two semicircular tubes, under the action of the threaded rod, the threaded rod is rotated, and the threaded rod will be extended and retracted on the inner wall of the L-shaped plate. During the extension and retraction process, the threaded rod will drive the clamps to move synchronously until the two adjacent clamps completely clamp the pipeline, so that the leak stopper and the pipeline can be fixed for the second time, which is beneficial to prevent the leak stopper from shifting and loosening on the outer surface of the pipeline, thereby facilitating the normal use of the pipeline.

[0007] Preferably, one end of the threaded rod is fixedly connected to an operating block, and a protrusion is provided on the outer surface of the operating block.

[0009] Preferably, the outer surface of the threaded rod is threadedly connected with a screw hole block, and the screw hole block is arranged between the clamping plate and the L-shaped plate.

[0010] The effect achieved by the above components is: by setting a screw hole block and rotating the screw hole block so that one side of the screw hole block abuts against one side of the L-shaped plate, the threaded rod can be limited, which is helpful to prevent the threaded rod from rotating and causing the clamping plate to loosen the pipe.

[0011] Preferably, a round rod is fixedly connected to one side of the clamping plate, the outer surface of the round rod is slidably connected to the inner wall of the L-shaped plate, and a stopper is fixedly connected to one end of the round rod.

At the same time, the stopper can limit one end of the round rod, which is helpful to prevent the round rod from detaching from the inner wall of the L-shaped plate due to misoperation.

[0013] Preferably, a rubber plate is provided on one side of the two clamping plates that are close to each other, and one side of the rubber plate is fixedly connected to one side of the clamping plates.

[0014] The effect achieved by the above components is that by arranging the rubber sheet, one side of the clamping plate can be replaced to contact the outer surface of the pipe, and the friction between the clamping plate and the pipe is increased, so that the clamping plate clamps the pipe more tightly.

[0016] The effect achieved by the above components is: by inserting the metal strip into the auxiliary holes on both sides of the two semicircular tubes and tightening the metal strip, the metal strip can assist in fixing the two semicircular tubes and strengthen the connection between the two semicircular tubes.

[0017] Preferably, the two ends of the metal strip are respectively fixedly connected with a first mounting block and a second mounting block, a side of the second mounting block is fixedly connected with a pin, a side of the first mounting block is evenly provided with a plurality of sockets, and an outer surface of the pin is inserted into an inner wall of one of the sockets.

[0018] The effect achieved by the above components is: by setting the pin, when the metal strip is completely tightened, the pin is inserted into the inner wall of the corresponding socket, so that the tightened metal strip can be fixed, which is helpful to prevent the metal strip from loosening.

[0019] Preferably, one end of the latch is fixedly connected to a rubber block, and the cross-section of the rubber block is an isosceles trapezoid.

[0020] The effect achieved by the above components is: by setting the rubber block, one end of the rubber block is smaller, which is convenient for inserting into the inner wall of the hole, while the other end of the rubber block is larger, which can limit the position between the pin and the first mounting block, which is helpful to prevent the pin from detaching from the inner wall of the hole.

[0021] Compared with the prior art, the advantages and positive effects of the utility model are:

[0022] In the utility model, by arranging clamping plates at both ends of the two semicircular tubes, under the action of the threaded rod, the threaded rod can drive the clamping plates to move synchronously until the two adjacent clamping plates completely clamp the pipeline, so that the leak stopper and the pipeline can be fixed for the second time, which is beneficial to prevent the leak stopper from shifting and loosening on the outer surface of the pipeline, thereby facilitating the normal use of the pipeline.
