Description

Technical Field

[0001] The utility model relates to the technical field of water pipe plugs, in particular to a drainage pipe plug with a filtering function. Background Art

[0002] After the electromechanical engineering has finished the drainage pipe in the bathroom pipe well, the drainage pipe mouth is usually blocked with tape or a pipe cap. After the bathroom water test is completed, the water will be discharged through the reserved drainage port of the pipe well. Since there is a lot of sediment in the discharged water, in order to prevent the drainage pipe from being blocked, the tape or pipe cap that blocks the drainage port is usually removed and a filter net is installed to drain the water. The patent document with announcement number CN218543596U discloses a drainage pipe plug with filtering function, which relates to the technical field of water pipe plugs; a large diameter pipe at the lower end of the step pipe is fixedly inlaid with several sealing rings, and the large diameter pipe at the lower end of the step pipe is sealed and sleeved on the drainage pipe through a sealing ring, and a through hole is fixedly set on the small diameter pipe at the upper end of the step pipe, and a filter net is sleeved on the outer wall of the small diameter pipe, and a rubber plug is inserted into the inner cavity of the small diameter pipe, and a side slot is fixedly set on the rubber plug. In the above technical solution, the plug is fixed by the friction between the sealing ring and the drain pipe, and a certain friction is generated by squeezing the sealing ring and the inner wall of the drain pipe. When the pressure inside the drain pipe is too high for a long time, a certain thrust will continue to be generated on the drain pipe. When the pressure inside the drain pipe is too high, the plug may be pushed out. For this reason, we propose a drain pipe plug with a filtering function. Utility Model Content
