Description

The drain member of face washing basin member

The utility model relates to the fluid line accessory, makes the field in particular for the sewer pipe spare of the dishware sanitaryware of washing one's face.

Existing ceramic washer washbasin; water member is a tube coupling under it; tube coupling top is that turned welt is circular; be used to withhold on the pad of drain member of face washing basin hole shoulder end face and seal; drainage hole is stretched out in the tube coupling bottom; be equipped with screw thread on it; spiral gland matches with it; with the packing ring roof pressure on lower surface, drain member of face washing basin hole; because the overflow water of general ceramic washer washbasin through the inner passage, and behind the eyelet that presets on the above-mentioned tube coupling wall, enters sewer from the tube coupling inner chamber from overfall again; the problem that this structure exists is; on the one hand, there is water to accumulate all the time in the gap in above-mentioned tube coupling outer wall and drain member of face washing basin hole, simultaneously; this gap is that overflow water must be through part, and the threaded engagement portion of its gland and tube coupling usually can become leakage point.Although (also adopt filling sealings such as raw material, long and other reason is always easily leaked owing to service time) uses account bitterly; On the other hand, owing to limited by positional factor, eyelet is less on the tube coupling wall, becomes the unimpeded bottleneck of overflow water, so make water diffuse out the washbowl ground of getting wet often because of the overflow water discharge value is little.

This evil is to overcome above the deficiencies in the prior art part and a kind of drain member of face washing basin member is provided with novel purpose, to solve tube coupling screw thread place leakage problem.

The purpose of this utility model is realized by the following technical programs: a kind of drain member of face washing basin member comprises upper fastener and following pipe fitting and bolt and nut; The top of upper fastener is provided with one and is used for the annulus that seals mutually through packing ring and drain member of face washing basin hole shoulder end face, and the upper fastener bottom is one to have the U-shaped bar of bolt hole on it; The top of this time pipe fitting is provided with one and is used for the annulus that seals mutually through packing ring and lower surface, drain member of face washing basin hole, and this annulus middle part is provided with a horizontal stripe that has bolt hole on it, and following pipe fitting bottom is a cylindrical shape tube coupling; Above-mentioned bolt and nut is connected upper fastener by two bolts hole with following pipe fitting.

In view of technique scheme, the annulus of upper fastener and drain member of face washing basin hole shoulder end face are by washer sealing, and the annulus of following pipe fitting and this drainage hole lower surface are by another washer sealing; Upper fastener is connected by bolt with following pipe fitting, through the bolt reinforcing above-mentioned two packing rings are compressed, realize sealing function, on structure, reduced by place's seal point on the whole, and what reduce is that original screw thread seals the seal point that this is easy to leak, simultaneously, " bottleneck " of original overflow water discharging limits---and tube coupling cinclides eye has not existed yet.Overflow water has reduced the overflow water exhaust resistance through the inner overflow ducts of overfall, washbowl, directly enter in the drain member of face washing basin hole and discharge.Thereby the utility model sealing performance is improved, and the overflow water discharging is more unimpeded, can not occur the trouble that the sealing of pipe fitting screw thread is leaked and overflow water outwards diffuses out again.

Below in conjunction with accompanying drawing the utility model is described in detail:

Fig. 1 Fig. 2 is respectively the stereogram of the utility model upper fastener and following pipe fitting;

Fig. 3 is the assembling section under the behavior in service of the present utility model.

In conjunction with Fig. 1 Fig. 2, Fig. 3 illustrates, and upper fastener 1 is the sectional drawing along A-A line shown in Figure 1, and following pipe fitting 2 is the sectional drawings along B-B line shown in Figure 2.The upper fastener top is an annulus (circular slab of center drilling), and the internal orifice of this annulus is provided with a groove inclined-plane 1a, as using the plug shutoff.The upper fastener bottom is a U-shaped bar, has bolt hole 1b on it.The circumscribed circle diameter of the cross section of U-shaped bar should be less than washbowl 7 drainage hole 7a diameters, i.e. requirement can conveniently be inserted it in this drainage hole, and packing ring 3 places between drainage hole shoulder end face and the upper fastener annulus, seals.Following pipe fitting top is an annulus, there is a horizontal stripe 2c at its middle part, be the fluid passage 2a that its central hole location forms two semicircles, have bolt hole 2b on the horizontal stripe, following pipe fitting bottom is a cylindrical shape tube coupling, and nut b preferably connects firmly the place, bolt hole position at following pipe fitting, bolt 5 reaches upper fastener down through above-mentioned two bolts hole, and pipe fitting is connected and fixed, and pipe fitting is pressed on down packing ring 3 on the shoulder end face of the mouth of a river, and pipe fitting is being descended packing ring 4 roof pressures on the lower surface, the mouth of a river, realize sealing.Bolt 5 heads have notch, and with easy disassembly, what should illustrate is, following pipe fitting upper bolt hole 2b can make screwed hole, directly cooperates with bolt, and this is that routine is equal to replacement, should belong to protection domain of the present utility model; The utility model not only is confined to the use of washbowl, and all structurally identical or approximate uses should belong to protection domain of the present utility model.
