DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a base plate interposed between a toilet body and a low tank.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG.
A base plate 2 is interposed between the toilet body 1 and the low tank 3, and the base plate 2 is fastened and fixed to the toilet body 1 via a close-up bolt 4. 2 is deformed, the float valve 9 of the low tank 3 is misaligned, the adhesion of the packings 6, 7, 8 is deteriorated, water may leak from the sealing bolt 4, and local cleaning on the base plate 2 may be performed. The operation section 11 of the apparatus is also deformed and moved downward by the tightening of the closing bolt 4, and the opening 1 of the low tank cover 10 is
There is a problem that the matching between the upper surface 0a and the upper surface of the operation unit 11 is deteriorated.

[0003]

SUMMARY OF THE INVENTION The present invention has been devised in view of the above-mentioned conventional problems, and does not provide a base plate capable of reducing the deformation of an operation portion or the like even when tightened to a main body side with a close-tightening bolt. The gist of this is that the float valve hole inserted between the toilet body and the low tank, into which the float valve of the low tank is inserted, and the operation unit installation surface where the operation unit of the local cleaning device is installed, are densely located in the middle. In a base plate having a bolt hole for a tying bolt, a notch groove for partitioning and separating the operation portion installation surface is formed over an outer periphery of the bolt hole and a part of an outer periphery of the float valve hole. .

[0004]

[Operation] When the tightening bolt is inserted into the bolt hole and the tightening bolt is tightened to the toilet body side, the tightening of the tightening bolt lowers only the vicinity of the bolt hole through the notch groove, and installs the operation unit. Since the section installation surface is partitioned and separated by the cutout grooves, the operation section can be arranged at a favorable position without falling downward.

[0005]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a plan view of a base plate, and FIG. 2 is a cross-sectional view of a main part of the base plate when the base plate is installed on a toilet body. The base plate 2 has a float valve hole 2 through which the float valve 9 of the low tank 3 is inserted.
a is formed, and the outer periphery of the float valve hole 2a is
A base plate packing mounting portion 2e on which the base plate packing 7 is mounted is formed, and an operation portion installation surface 2c on which the operation portion 11 of the local cleaning device is installed is formed on the base plate 2. A bolt hole 2b through which the sealing bolt 4 is inserted is formed between the installation surface 2c and the base plate packing receiving portion 2e. 2f is formed.

In this embodiment, a notch groove 2d penetrating vertically is formed over the outer periphery of the bolt hole 2b and a part of the outer periphery of the base plate packing mounting portion 2e. As a result, the float valve hole 2a and the bolt hole 2b are separated from the operation section installation surface 2c.

As shown in FIG. 2, such a base plate 2 is disposed on the upper surface of the toilet body 1 and a tight bolt 4 is inserted from above into a bolt hole 2b. At this time, a base plate packing 7 is mounted on the base plate packing mounting portion 2e, and the base plate 2 is opposed to the base plate packing 7 at this time. A lower packing 6 is arranged on the back side between the toilet body 1 and the float valve 9 of the low tank 3 is inserted into the float valve hole 2a from above so that the valve packing 9a contacts the bottom surface of the low tank 3. The low tank packing 8 is disposed on the base plate packing 7 on the outer periphery of the float valve 9 so as to be watertight. 6, the base plate packing 7,
Low tank gasket 8 and low tank 3 and toilet body 1
The watertightness between them is ensured, and an operation unit 11 for operating the local cleaning device is installed on the operation unit installation surface 2c of the base plate 2.

In the present embodiment, the tightly coupled bolt 4 is connected to the nut 5
When the screw is tightened by screwing, the periphery of the bolt hole 2b and a part of the outer periphery of the float valve hole 2a are moved downward by tightening, but the operating portion installation surface 2c is partitioned by the notch groove 2d. As a result, the operation unit installation surface 2c is maintained at a predetermined height without moving downward even by tightening the close-up bolt 4, and therefore, is installed on the operation unit installation surface 2c. The height of the upper surface of the operation unit 11 is also maintained at a predetermined height. That is, the upper surface of the operation unit 11 has the opening 1 formed in the low tank cover 10.
It can be installed in a flush state in alignment with 0a, the appearance is refreshed, and the operation of the operation unit 11 can be easily performed.

The center of the float valve 9 with respect to the float valve hole 2a does not occur because the deformation of the base plate 2 is reduced, and the packings 6, 7, 8 can function well to prevent water leakage. Become.

[0010]

According to the present invention, a float valve hole interposed between a toilet body and a low tank, into which a float valve of the low tank is inserted, and an operation section installation surface on which an operation section of a local cleaning device is installed are provided in the middle. In the base plate in which the bolt hole for the close-tightening bolt is formed, a cutout groove for partitioning and separating the operation portion installation surface is formed over the outer periphery of the bolt hole and a part of the outer periphery of the float valve hole. Since the notch groove is formed even when the tightening bolt is tightened, the operating part installation surface does not move downward, and the operating part is accurately placed at a predetermined position and has a neat appearance It can be.
