Detailed Description

The present utility model will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1 to 7, the utility model provides a floor drain core assembly, which comprises an outer cylinder 1, wherein a positioning ring 11 is outwards extended from the top of the outer cylinder 1, a plurality of connecting strips 12 are downwards extended from the outer cylinder 1, a base 13 is formed at the bottom, a mounting column 2 is vertically arranged in the center of the base 13, a mounting hole 21 is arranged in the mounting column 2, an umbrella-shaped sealing plate 3 is arranged in the mounting hole 21, the umbrella-shaped sealing plate 3 comprises a lower rod part and a top panel part, the lower rod part is inserted into the mounting hole 21, a compression spring or a repulsive magnet is arranged between the lower rod part and the top panel part, the top panel part of the umbrella-shaped sealing plate 3 is in contact sealing with the inner side wall of the outer cylinder 1, and an annular sealing gasket 4 matched with floor drain inner diameters of different sizes is sleeved on the outer side surface of the outer cylinder 1.

In the above scheme, the outer diameter of the outer cylinder 1 is 32mm, the inner diameter of the annular sealing gasket 4 is matched with the outer diameter of the outer cylinder 1, and the outer diameter of the annular sealing gasket 4 is 40mm, 50mm or 75mm.

In addition, a pull ring 5 is hinged on the inner side wall at the top of the outer cylinder 1.

In addition, the mounting hole 21 is a step hole, the spiral sleeve 6 is arranged in the mounting hole 21, the inner side surface and the outer side surface of the spiral sleeve 6 are smooth surfaces, the bottom of the umbrella-shaped sealing plate 3 is inserted into the spiral sleeve 6, the rod part below the umbrella-shaped sealing plate 3 is inserted into the spiral sleeve 6, and friction force can be reduced when the umbrella-shaped sealing plate 3 rotates, so that the umbrella-shaped spiral sleeve 6 rotates faster.

In addition, the top surface of the umbrella-shaped sealing plate 3 is provided with a series of drainage convex strips 31 which are distributed at equal angles and spirally spread outwards.
