Description

[Detailed Description of the Invention] The present invention relates to a low tank and toilet bowl mounting structure of a low tank closed type toilet bowl in which the low tank is placed and fixed on the upper surface of the rear side of the toilet bowl.

FIG. 1 is an exploded perspective view showing a conventional low tank closed toilet bowl 1, and FIG. 2 is an exploded perspective view of the low tank 2.
FIG. 3 is a partial cross-sectional view showing how the toilet bowl 3 is installed. As shown in the figure, a conventional low tank closed toilet bowl 1
A pedestal 4 is formed on the upper surface of the rear side of the toilet bowl 3, and the low tank 2 is connected and fixed to the pedestal 4 with bolts 5 or the like. A ball tap 6 is attached to the upper left side wall of the low tank 2 so that one end thereof passes through to the outside, and is connected to a water supply pipe 8 through a water supply pipe 7. Further, a handle 9 for operating a float valve is attached to the upper part of the right side wall of the low tank 2, and is connected to a float valve 10 fixed to the bottom surface inside the low tank 2.

However, in order to connect the low tank 1 and the toilet bowl 2, first, the bolt 5 is passed through the through hole 14 provided on the bottom of the low tank 2 and fixed with a nut 11. The nut 12 had to be screwed into the base 4 from the underside of the base 4. This fixing method of tightening nuts from the bottom side of the pedestal 4 causes the low tank 2 to get in the way, and moreover, the work must be done in an awkward position in a toilet with limited space, which may cause wobbling. , uneven tightening, etc. may occur. As a result, the sealing function of the gasket 13 disposed between the low tank 2 and the toilet bowl 3 was lost, resulting in the problem of water leakage.

Therefore, in view of the above-mentioned drawbacks of the conventional low-tank closed toilet bowl, the present invention has been developed to improve and eliminate the drawbacks. is inserted from the bottom side of the pedestal and fixed, and a screw member is inserted from the inner side of the low tank into a through hole in the bottom wall of the low tank that is bored at a position corresponding to the through hole, and the screw member is connected to the double screw. It is an object of the present invention to provide a mounting structure for a low tank and a toilet bowl in which the low tank can be attached to the toilet bowl from the inner side of the low tank by screwing into the inner threaded hole of the bolt exhibiting the structure.

The configuration of the present invention will be explained below based on the embodiments shown in the drawings. Note that the same reference numerals as in the conventional case represent the same members.

Figure 3 shows the low tank 2 and toilet bowl 3 according to the present invention.
FIG. 3 is a longitudinal cross-sectional view showing an example of a mounting structure. As shown in the figure, in this embodiment, to attach the low tank 2 to the toilet bowl 3 (see Figure 1), first insert a bolt 1 with an internal and external double screw structure into the through hole 15 of the pedestal 4.
6 is inserted from the bottom side of the base 4. and,
Insert the nut 17 from the top side of the pedestal 4, and then tighten the bolt 1
The bolt 16 is fixed to the base 4 by screwing it into the outer screw 18 of No.6. After that, the low tank 2 is placed on the upper surface side of the pedestal 4 via the packing 13. After the low tank 2 is placed on the pedestal 4 in this way, the through hole 15 of the pedestal 4 is
Insert the screw member 1 from the inner surface of the low tank into the through hole 14 bored in the bottom wall 2a of the low tank at a position corresponding to
Insert 9. Then, the screw member 19 is screwed into the inner screw hole 20 of the bolt 16 having the above-mentioned internal and external double screw structure, and the low tank 2 is connected and fixed to the pedestal 4 of the toilet bowl 3, thereby obtaining a low tank closed type toilet bowl. .

In this way, in this embodiment, before placing the low tank 2 on the pedestal 4, the through hole 1 of the pedestal 4 is
A bolt 16 having an internal and external double screw structure is inserted into and fixed to the tank 5, and the bolt 16 can be fixed relatively easily because the low tank 2 does not get in the way of the work as in the conventional case. Further, since the fixing of the low tank 2 is performed from the inner surface of the tank 2, a sufficient working space can be secured, the work is easy, and uniform fastening can be performed.

By the way, the technique of the present invention is not limited to the embodiment shown in FIG. 3, and the shape of the low tank 2, the shape of the screw member 19 and the bolt 16, etc. can be changed as appropriate.

As explained above, in the present invention, since the low tank can be attached from the inner surface of the low tank, it is possible to secure a sufficient working space. Therefore, the installation work is easy to perform, uniform fastening is possible, and installation defects such as looseness and uneven tightening do not occur as in the past. Therefore, there is no problem of water leakage.
