【考案の詳細な説明】
本考案は、水洗便器に好適に使用される水洗タンクに関
する。[Detailed Description of the Invention] The present invention relates to a flush tank suitably used in a flush toilet.
従来、例えば実公昭４７−１６９４４号公報に記載され

ツトをねじ着して傾斜壁部の外面にシート状パツキンを
圧接するようになした水洗タンクが存する。Conventionally, as described in Japanese Utility Model Publication No. 47-16944, an inclined surface is formed on the upper surface of the peripheral edge of a through hole in the bottom of the tank body, and a sheet-like packing is laid along this inclined surface. Insert a short cylindrical body with an inclined wall at the top and a small diameter section at the bottom into the hole, screw a tightening nut onto the outer surface of the small diameter section, and attach a sheet-like packing to the outer surface of the inclined wall. There are water wash tanks that are pressure-contacted.
しかしながら従来の水洗タンクでは、傾斜面が形成され

機械的強度がこの部分で低下し締付ナツトを強く締付け
すぎたり荷重や水圧等により変形しやすい欠点があった
。However, in conventional flush tanks, the part where the slope is formed is thinner than the other parts of the tank body.
The mechanical strength decreases in this part, and there is a drawback that it is easily deformed by tightening the tightening nut too strongly or by loads, water pressure, etc.
又、透孔周縁上面の傾斜面に沿ってシート状パツキンが
敷設されているが傾斜面は周状に形成されるため、パツ
キンの敷設が容易でないし、パツキンがシート状では充
分な厚みを持たせることはできないから弾性変形を充分
に利用することができない腰パツキンがシート状では伸
びを生じたりしやすく、パツキンによる封水効果が充分
得られないおそれがあった。In addition, sheet-like packing is laid along the sloped surface of the upper surface of the periphery of the through hole, but since the sloped surface is formed in a circumferential shape, it is not easy to lay the packing, and if the packing is in sheet form, it is not thick enough. Since the elastic deformation cannot be fully utilized because the elastic deformation cannot be fully utilized, the waist gasket tends to stretch when it is in sheet form, and there is a risk that the water sealing effect of the gasket may not be sufficiently obtained.

されてなる水洗タンクに存する。The present invention was made with the aim of eliminating the above-mentioned drawbacks, and its gist is that a through hole is provided at the bottom of the tank body, an inclined surface is formed on the upper surface of the periphery of the through hole, and The lower surface of the peripheral edge is made thick by protruding downward, and the lower surface of the thick portion is a flat surface, and an annular groove is provided in the inclined surface, and a groove having a substantially circular cross section is provided in the annular groove. An elastic water sealing ring is fitted, a short cylinder is inserted into the through hole, and the short cylinder has an inclined wall between an upper large diameter part and a lower small diameter part, The large-diameter portion of the short cylindrical body projects into the tank body, and the upper end opening is opened and closed by a discharge valve. Facing - An elastic water seal ring is formed on the outer surface of the inclined wall of the short cylinder by screwing a tightening nut onto the external thread provided on the outer circumferential surface of the small diameter part of the short cylinder that protrudes below the tank body. It resides in a flushing tank whose body is pressed together.
以下、本考案の一例を図面と共に説明する。An example of the present invention will be described below with reference to the drawings.

機械的強度の向上を図っている。A through hole 2 is provided at the bottom of the tank body 1, and the lower surface of the peripheral edge of the through hole 2 is made thicker by protruding downward to improve mechanical strength.
厚肉部の下面は平坦面とされて締付ナツト１１の締付け
がしやすくなされている。The lower surface of the thick portion is made flat so that the tightening nut 11 can be easily tightened.
透孔２の周縁部上面には傾斜面４が形成されている。An inclined surface 4 is formed on the upper surface of the peripheral edge of the through hole 2 .
傾斜面４には環状凹溝５が設けられ、該環状凹溝５にコ

該タンク本体１の透孔２には短筒体７が挿着されている
。A short cylindrical body 7 is inserted into the through hole 2 of the tank body 1.
該短筒体７は上部に径大部８、下部に径小部９が設けら
れ、該径大部８と径小部９の間に傾斜壁部１０が設けら
れている。The short cylindrical body 7 has a large-diameter portion 8 at the top and a small-diameter portion 9 at the bottom, and an inclined wall portion 10 is provided between the large-diameter portion 8 and the small-diameter portion 9.
該径小部９の外周面には雄ねじ部が設けられ、該タンク
本体１の底部下方より締付はナツト１１が該径小部９の
雄ねじ部にねじ着されることにより、短筒体７が傾斜壁
部１０の外面に弾性封水環体６が圧接される。A male threaded portion is provided on the outer peripheral surface of the small diameter portion 9, and tightening is performed by screwing a nut 11 onto the male threaded portion of the small diameter portion 9 from below the bottom of the tank body 1. The elastic water seal ring 6 is pressed against the outer surface of the inclined wall portion 10.
該短筒体７の径大部８の上端部はタンク本体１内におい
て底部より一定の高さに突出され吐水弁１２の受は部１
３が形成される。The upper end of the large-diameter portion 8 of the short cylinder body 7 protrudes from the bottom of the tank body 1 to a certain height, and the receiving portion of the water discharge valve 12 is located at the portion 1.
3 is formed.
吐水弁１２は適時に上下して吐水弁受は部１３を開閉し
て短筒体７より水を吐出させるものである。The water discharge valve 12 is moved up and down at appropriate times, and the water discharge valve receiver opens and closes the portion 13 to discharge water from the short cylindrical body 7.
該短筒体７は合成樹脂あるいは金属で、タンク本体１と
は別体で成形し、吐水弁受は部１３を精度よく形成する
ことができる。The short cylindrical body 7 is made of synthetic resin or metal and is molded separately from the tank body 1, and the water discharge valve receiver portion 13 can be formed with high precision.
水洗タンクでは、吐水口部において、短筒体７を締付は
ナツト１１で締付は過ぎると、タンク本体１の透孔２の
周縁部３や短筒体７を変形させようとする力が掛るが、
断面略円形の弾性封水環体６が環状凹溝５に嵌合され、
短筒体７の傾斜壁部１０の外面に圧接されることにより
封水は良好であり、締付はナツト１１で短筒体７を強固
に締付けする必要はない。In the flush tank, if the short cylindrical body 7 is tightened with the nut 11 at the spout, a force that tends to deform the peripheral edge 3 of the through hole 2 of the tank body 1 and the short cylindrical body 7 will be generated. It takes, but
An elastic water sealing ring body 6 having a substantially circular cross section is fitted into the annular groove 5,
Since the short cylinder body 7 is pressed against the outer surface of the inclined wall portion 10, water sealing is good, and there is no need to firmly tighten the short cylinder body 7 with the nut 11.
又、タンク本体１の透孔２の周縁部３に傾斜面４が形成
されているから、短筒体７の傾斜壁部１０と締付はナツ
ト１１による締付は力は、透孔２の周縁部３において上
下方向と左右方向に分散し、しかも透孔２の周縁部下面
は下方に突出されて厚内とされているので機械的強度が
すぐれたものとなり、透孔２の周縁部３及び短筒体７が
変形することがなくなる。In addition, since the inclined surface 4 is formed on the peripheral edge 3 of the through hole 2 of the tank body 1, the force of tightening the short cylinder body 7 with the inclined wall portion 10 using the nut 11 is the same as that of the through hole 2. The peripheral edge part 3 is dispersed in the vertical and horizontal directions, and the lower surface of the peripheral edge of the through hole 2 is protruded downward and is made thicker, so it has excellent mechanical strength, and the peripheral edge part 3 of the through hole 2 And the short cylindrical body 7 will not be deformed.
本考案水洗タンクは、上記に記載された構成になされて
いるから、組み立てが容易であり、タンク本体の透孔か
らの浅水は傾斜面の環状凹溝に嵌合される断面略円形の
弾性封水環体によりなされ、前記弾性封水環体は締付ナ
ツトの締付は力により短筒体の傾斜壁部に圧接されて浅
水が完全に防止されるのである。Since the flushing tank of the present invention has the configuration described above, it is easy to assemble, and the shallow water from the through hole in the tank body is absorbed by an elastic seal with a substantially circular cross section that fits into the annular groove on the inclined surface. When the tightening nut is tightened, the elastic water sealing ring is brought into pressure contact with the inclined wall portion of the short cylindrical body, completely preventing shallow water from entering.
更に、締付はナツトによる締付は力は透孔の周縁部の傾
斜面で分散し、しかも透孔の周縁部下面は下方に突出さ

なりタンク本体の透孔の周縁部が変形して浅水が起った
り、短筒体が変形して吐水弁の閉鎖が不完全になって水
が無駄になることがない。Furthermore, when tightening with a nut, the force is dispersed on the sloped surface of the periphery of the through hole, and the lower surface of the periphery of the through hole is thickened by protruding downward, resulting in excellent mechanical strength. This prevents water from being wasted due to deformation of the periphery of the through hole in the tank body, causing shallow water, or deformation of the short cylindrical body, resulting in incomplete closing of the water discharge valve.
