Specific embodiment
Present invention is further described in detail with reference to the accompanying drawings and detailed description: a kind of referring to Fig. 1 to Fig. 6
Water return preventing floor drain, including barrel-type casing 1,1 top edge of shell is provided with flange 11, if being provided at the top of the shell 1
Dry first through hole 12,1 side of shell are provided with discharge outlet 13, and rotation is provided with first rotating shaft 2, institute at the top of the shell 1
It states first rotating shaft 2 and is circumferentially provided with several winding rods 21, be provided with impeller in the first rotating shaft 2 of 21 lower section of winding rod
22,2 peripheral, axial of first rotating shaft is provided with several first sliding grooves 23, and sliding is provided with several knives in the first sliding groove 23
Piece 24, several blades 24 are fixed in circular ring shape blade holder 25, and 1 inboard, upright of shell is provided with several second sliding slots
14, sliding is provided with rack gear 3 in several second sliding slots 14, and several 3 upper ends of rack gear connect a slip ring jointly
4, the slip ring 4 is rotatablely connected with the blade holder 25, is provided with fixed plate 15 in the shell 1, the fixed plate 15 with
It is provided with spring 5 between the blade holder 25,2 bottom of first rotating shaft is provided with first gear 26, in the fixed plate 15
Rotation is provided with several second shafts 16, and the second gear engaged with the first gear 26 is provided in second shaft 16
17, worm screw portion 18 is additionally provided in second shaft 16, rotation is provided with third shaft 19, the third in the shell 1
It is provided with worm gear 6 in shaft 19, there is cutting face 61 on the worm gear 6,61 width of cutting face is less than the tooth of the worm gear 6
