Description

Technical Field

[0001] The utility model relates to the technical field of novel equipment for water supply and drainage engineering, in particular to a novel assembled functional device for water supply and drainage engineering. Background Art

[0002] The major of water supply and drainage engineering takes the social cycle of water as its research object, and its research content involves urban water resources, urban municipal water engineering, construction water engineering, industrial water engineering, agricultural water engineering, water-saving industry and other fields. Water supply and drainage science and engineering generally refers to urban water supply system and drainage system (municipal water supply and drainage and construction water supply and drainage), referred to as water supply and drainage. Water supply is to purify water into tap water that meets the standards of production and living water through a series of physical and chemical means, and then transport tap water to thousands of households through the well-connected urban water network. In water supply and drainage engineering, assembled functional devices are often used to connect drainage pipes.

[0003] Chinese utility model disclosure specification CN215908641U discloses a novel assembled functional device for water supply and drainage engineering. When using the device, one end of the external water pipe is inserted into the reducer, and the fixing ring is rotated. The fixing ring moves toward one end of the reducer through the cooperation of the external thread and the internal thread, and fixes the external water pipe. After completion, the extrusion block is aligned with the extrusion groove, and the dial wheel is turned. The dial wheel drives the threaded rod to rotate, because the threaded rod is screwed with the second fixing block, and drives the extrusion block to move, so that the extrusion block is tightly attached to the extrusion groove, and fixes the fixing ring to prevent loosening.

[0004] In summary, the method of fixing the fixing ring by rotating the dials one by one is rather troublesome, and the user needs to rotate multiple dials to make the extrusion block engage with the extrusion groove. Utility Model Content
