A vertical tube with an open slot at the lower part is located at the medial of the up cover roof. The gear is combined with the shaft of the vertical tube through the open slot. The draft tube is a tooth profile rod located in the vertical tube and combined with the gear disposed at the lower part of the vertical tube. A tubular dropping is covered outside the vertical tube. Racks are fixed in the inner cavity in the longitudinal direction. The tubular dropping is matched with the gear arranged on the vertical tube through the racks. Thus the peculiar smell in the sewer pipe can be sealed without water. The utility model has advantages of a simple structure, the proper water flow, a good sealing effect, and absolved water sealing. At the same time, the problem of cleaning the floor drain can be avoided.

Description

A kind of dry-sealing floor drain

The utility model relates to a kind of floor drain, relates to the dry-sealing floor drain that a kind of kitchen, washroom sewer pipe are used in particular, belongs to a kind of improvement of floor drain.

At present, the floor drain that kitchen, washroom sewer pipe use is generally the hydrolock structure, the upper port of this floor drain has an annular water tank, the lower edge of floor drain loam cake is suspended from the annular water tank, form water seal after being full of water in the groove, the peculiar smell that has blocked sewer pipe can not pass through in the floor drain inlet chamber it.But, need not when the floor drain long period, water in the annular water tank is done solid or water shutoff quantity not sufficient or tank internal memory hydrospace can't be formed water seal by the solid foreign materials filling time, a large amount of peculiar smell will be by in the floor drain inlet chamber, have to be regular add water or clear up annular water tank in the floor drain annular water tank brought inconvenience for people's daily life.

The purpose of this utility model provides a kind of dry-sealing floor drain, and it not only can enter indoor easily by the peculiar smell in the floor drain prevention sewer pipe, and has removed the trouble that often adds water and cleaning in floor drain from.

The purpose of this utility model is achieved in that it includes loam cake, drain hole, it is characterized in that being stamped the stile of tubular, and there is a standpipe inboard of last lid top panel, and the standpipe lower end is provided with open slot, and gear cooperates with the standpipe axle by open slot; Guide peg is the profile of tooth bar, and guide peg places standpipe to cooperate with the gear of standpipe lower end; Also be with tubular in the outside of standpipe and weigh down, the inner chamber that tubular is weighed down vertically is fixed with tooth bar, and tubular is weighed down by the gears engaged on tooth bar and the standpipe; Sealing plate is fixed on the lower end of guide peg, and sealing plate weighs down by tubular and the end opening of tubular stile is tightly connected.

The utility model has the advantages that, owing on sealing plate, fix a toothed guide peg, sealing plate reaches under the effect of weighing down with the tubular of gears engaged at guide peg, loam cake tubular stile end opening is sealed, constitute an inner chamber that surrounds by tubular stile and sealing plate, water still can not sealed the interior peculiar smell of sewer pipe like this, have simple in structure, the smoothness of leaking water, good sealing effect, without the characteristics of water seal, removing the trouble of cleaning floor drain simultaneously from, is a kind of novelty and the floor drain product that shows unique characteristics.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is a concrete structure generalized section of the present utility model.

In Fig. 1, drain hole 1 is arranged at the top of loam cake 4, and loam cake 4 also has the stile 12 of tubular, in loam cake 4 top board inboards a threaded umbilical opening 2 is arranged, and standpipe 3 is threaded by umbilical opening 2 with loam cake 4, and the end opening of standpipe 3 has two open slots 6 of symmetry.Gear 7 is two, and place 3 of the open slot 6 and the standpipes of two gear 7 symmetries cooperate.Guide peg 5 is housed in standpipe 3, on guide peg 5, has with gear 7 to cooperate teeth.The connecting hole at the lower end of guide peg 5 and sealing plate 10 middle parts is connected and fixed with nut after pegging graft.Be fixed with the sealing plate 10 of guide peg 5, be tightly connected by the end opening of tubular bob 8 with tubular stile 12, tubular is weighed down two tooth bars that are provided with vertical symmetry in 8.Tubular is weighed down 8 gravity greater than sealing plate 10, and the gravity of tubular bob 8 is tightly connected the sealing plate 10 and the end opening of tubular stile 12 by the conduction of gear 7.

Under normal conditions, sealing plate 10 is by guide peg 5, weigh down under 8 the effect with guide peg 5 meshed gears 7 and with the tubular of gear 7 engagements, and with the end opening sealing of the tubular stile 12 of loam cake 4, the peculiar smell in the sewer pipe is enclosed in the pipeline by floor drain and can not enters indoor.When water enters floor drain down, following water flows into the inner chamber 11 of floor drain from the drain hole 1 of floor drain, the weight of water itself is pressed on the sealing plate 10, water on being pressed in sealing plate 10 is great, and sealing plate 10 moves down synchronously with guide peg 5 when tubular is weighed down 8 weight, drives with guide peg 5 meshed gears 7 to rotate, gear 7 weighs down tubular by tooth bar 9 and moves up, sealing plate 10 breaks away from the end opening of loam cake tubular stiles 12, and sealing plate 10 is opened end opening, and following water flows into the sewer from floor drain.Instantly current to the greatest extent, when tubular was weighed down 8 weight greater than the weight of sealing plate 10, tubular was weighed down 8 and is moved down, and the tooth bars 9 that weigh down in 8 by tubular rotate gear 7, move on the guide peg 5 of gear 7 drives and gears engaged, sealing plate 10 is sealed the end opening of loam cake 4 tubular stiles 12 again.
