Description

Combined type antiseep flange

Technical field

The utility model relates to a kind of flange and relates in particular to a kind of combined type antiseep flange being connected with blow-off pipe for closestool bottom.

Background technology

Consult Fig. 1 (a), Fig. 1 (b), existing closestool bottom is mainly the flange of taking as shown in Fig. 1 (a), Fig. 1 (b) with being connected of blow-off pipe, by body 1 and clay 2, formed, consult Fig. 2, on ground 3 smooth blow-off pipes 4 for external diameter be that 110mm internal diameter is that the standard size of 105mm and mouth of pipe cutting are neat and in the situation that make toilet bowl sewage draining mouth center aim at the center of blow-off pipe 4 in installation process, really can make bottom and the ground 3 of clay 2 be adjacent to, top and toilet base plate 6 are adjacent to, and toilet 6 is not seeped water in water-rinsing process;

Consult Fig. 3 (a), Fig. 3 (b), but actual conditions are due to the deviation in constructor's work, the mouth of pipe of blow-off pipe 4 is all not too smooth, and mouth of pipe ground 3 is around also out-of-flatness, and in installation process, be difficult to make toilet bowl sewage draining mouth center to aim at the center of blow-off pipe 4, although the top of clay 2 can be adjacent to toilet base plate 5, but in the irregular situation of the mouth of pipe of blow-off pipe 4 and ground around 3 thereof, the bottom of clay 2 just has part and can not be adjacent to ground 3, thereby makes sewage a small amount of in toilet 6 flushing processes from bottom leaky to ground;

Consult Fig. 4 (a), Fig. 4 (b), also there is many times the position due to original standard blow-off pipe entrance in washroom not meet resident family's needs, will make in this case the position of blow-off pipe entrance be shifted, consider the thickness of accomodation ground and the convenience of displacement, all in most cases that to adopt external diameter be that 100mm internal diameter is that the standard water service pipe of 90mm is as blow-off pipe, due to the internal diameter of blow-off pipe 7 than the internal diameter of standard blow-off pipe 4 little 15mm, will make like this body 1 be withstood by the mouth of pipe of blow-off pipe 7, thereby the bottom of clay 2 can not contact with ground 3; Consult Fig. 5 (a), Fig. 5 (b), must cut away the mouth of pipe of part blow-off pipe 7 in this case, because the out-of-flatness of cutting also will make the bottom of clay 2, there is part not to be adjacent to ground 3, thereby also can make sewage a small amount of in toilet 6 flushing processes from bottom leaky to ground.

The specific embodiment

Consult Fig. 6 (a), Fig. 6 (b), Fig. 6 (c), Fig. 6 (d), on body 8, have flange 9, little percolation-proof seal channel 10, external screw thread 11, little guide head 12, little mudhole 13;

Wherein, little guide head 12 is taper;

Consult Fig. 7 (a), Fig. 7 (b), Fig. 7 (c), Fig. 7 (d), on regulating sleeve 14, have internal thread 15, large percolation-proof seal channel 16, large guide head 17, large mudhole 18;

Wherein, large guide head 17 is taper;

Consult Fig. 8, on little percolation-proof seal 19, have little elastic sealing strip 20;

Consult Fig. 9, on large percolation-proof seal 21, have large elastic sealing strip 22;

Consult Figure 10, the flange 9 on body 8 is wrapped in wherein by clay layer 23 completely.

Blow-off pipe 27 has a standard size in the ordinary course of things, external diameter at Chinese Industrial Standards (CIS) blow-off pipe 27 is 110mm, internal diameter is 105mm, and in this specific embodiment, the external diameter of the maximum of the large guide head 17 of taper is 102mm, and the external diameter of the maximum of the little guide head 12 of taper is 88mm;

First toilet 6 upset is made to base plate 5 upward or towards side, consult Fig. 6 (a) to Figure 13 (b), little percolation-proof seal 18 is arranged in little percolation-proof seal channel 10, large percolation-proof seal 21 is arranged in large percolation-proof seal channel 16, again regulating sleeve 14 is enclosed within on body 8, and rotate regulating sleeve 14 internal thread 15 and external screw thread 11 are fastened, little guide head 12 is in large mudhole 18;

The combined type antiseep flange having combined is arranged on base plate 5, little mudhole 13 is alignd with sewage draining exit 27, clay layer 23 is tightly being pasted on described base plate 5, down, movable toilet 6 makes large guide head 17, large percolation-proof seal 21 stretch in blow-off pipe 4 to the base plate 5 that turnover closestool 6 makes to install combined type antiseep flange again.

So because large guide head 17 is that taper is easy to make combined type antiseep flange of the present utility model to stretch in blow-off pipe 4 in toilet process is installed, due to the maximum of the large guide head 17 of taper and the gap of blow-off pipe 4 less, so substantially can there is not off normal in combined type antiseep flange center and blow-off pipe center, large elastic sealing strip 22 on large percolation-proof seal 21 just can prevent that sewage from emitting from blow-off pipe 4, does not have effluent seepage in flush toilets process.

Consult Figure 14 (a), Figure 14 (b), also there is many times the position due to original standard blow-off pipe entrance in washroom not meet resident family's needs, will make in this case the position of blow-off pipe entrance be shifted, considering the thickness of accomodation ground and the convenience of displacement, is all in most cases that to adopt external diameter be that 100mm internal diameter is that the standard water service pipe of 90mm is as blow-off pipe 7; Will rotate in this case regulating sleeve 14 departs from internal thread 15 and external screw thread 11, regulating sleeve 14 is pulled down from main flange, then toilet 6 upset is made to base plate 5 upward or towards side, main flange is arranged on base plate 5, little mudhole 13 is alignd with sewage draining exit 27, clay layer 23 is tightly being pasted on described base plate 5, and down, movable toilet 6 makes little guide head 12, little percolation-proof seal 19 stretch in blow-off pipe 7 to the base plate 5 that turnover closestool 6 makes to install main flange again.

So because little guide head 12 is that taper is easy to make main flange to stretch in blow-off pipe 7 in toilet process is installed, due to the maximum of the little guide head 12 of taper and the gap of blow-off pipe 7 less, so substantially can there is not off normal in main flange center and blow-off pipe center, little elastic sealing strip 20 on little percolation-proof seal 19 just can prevent that sewage from emitting from blow-off pipe 7, does not have effluent seepage in flush toilets process.

Consult Figure 15 (a), Figure 15 (b), the external screw thread 11 on body 8 can carry out various deformation, as having breach 24 at external screw thread 11 places; Consult Figure 16 (a), Figure 16 (b), the internal thread 15 on regulating sleeve 14 also can carry out various deformation, as having breach 24 at internal thread 15 places; When breach 24 is enough large, just not needing whole circle to rotate regulating sleeve 14 just can be fixing with body 8, only needs to rotate four/once enclosing, can fix with body 8.

Consult Figure 17, percolation-proof seal can carry out various deformation, as only having a slice elastic sealing strip 26 on percolation-proof seal 25, also can stop sewage to emit from blow-off pipe.
