Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明は給水装置に係り、特に小形の合成樹脂製受水槽
とポンプとを組合せる給水装置に関する。Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water supply device, and more particularly to a water supply device in which a small-sized synthetic resin water receiving tank and a pump are combined.
受水槽とポンプとを組合せて、受水槽内の水を加圧給水
する給水装置は、例えば特開昭61−286590号のように、
受水槽の上面にポンプを載置し、受水槽内側よりボルト
を貫通させてポンプを固定する方法をとつている。A water supply device that combines a water receiving tank and a pump to pressurize the water in the water receiving tank is disclosed in, for example, JP-A-61-286590.
A method of mounting the pump on the upper surface of the water receiving tank and fixing the pump by penetrating a bolt from the inside of the water receiving tank is adopted.
上記従来技術は、締付ナツトを回転するときの貫通ボル
トの供回り防止について配慮されておらず、ポンプの取
付け、取外しなどの保全作業性に課題を有すると考えら
れる。The above-mentioned prior art does not take into consideration the prevention of the rotation of the through bolt when the tightening nut is rotated, and is considered to have a problem in maintenance workability such as installation and removal of the pump.
つまり、上記従来技術は、単に、受水槽に内側よりボル

ツトを締付ける場合には、ボルトが回らないように受水
槽内側よりボルトを保持する必要がある。従つて、内側
に人が入れるようにするため、受水槽を複数個に分解し
た構造にする必要があつた。That is, the above-mentioned conventional technique is simply structured such that the bolt is penetrated from the inside to the outside in the water receiving tank, and the nut is tightened by this bolt via the pump holding metal fitting. Therefore, when tightening the nut, it is necessary to hold the bolt from the inside of the water receiving tank so that the nut does not rotate. Therefore, in order to allow people to enter inside, it was necessary to disassemble the water receiving tank into multiple parts.

脂のクリープにより固定力が低下し、ボルトも回転して
しまう。特に、ポンプ固定用のナツトが腐食などでボル
トに固着している場合には、ボルトとナツトが共回りす
る欠点がある。Also, when the nut is loosened in order to remove the pump from the water receiving tank, it is necessary to drain the water in the water receiving tank, disassemble the water receiving tank, and then enter it in order to fix the bolts. There is a drawback. Especially, if the water tank is made of synthetic resin, even if you try to fix the bolt by simply tightening the nut with other nuts and bolts as in the conventional example, the fixing force will decrease due to the creep of the synthetic resin and It will rotate. In particular, when the nut for fixing the pump is fixed to the bolt due to corrosion or the like, there is a drawback that the bolt and the nut rotate together.
本発明の目的は上記した従来例の欠点を改良し、ボルト
に自己保持性をもたせることで、保全性の良好な給水装
置を提供することにある。It is an object of the present invention to provide a water supply device having improved maintainability by improving the above-mentioned drawbacks of the conventional example and making the bolt self-holding.
上記目的は、合成樹脂製受水槽の一面にポンプを取り付

槽に取付け、前記保持体が受水槽の凹部の壁部に当接し
てボルトの回り止め作用を生じさせることにより達成で
きる。The above-mentioned purpose is to attach a pump to one surface of a synthetic resin water receiving tank, and in a water supply device that pressurizes and supplies water in the water receiving tank with a pump, a part of the water receiving tank is pushed outward to serve as a pump mounting portion, A bolt penetrating hole is formed at a position deviated from the center of the mounting portion, and a bolt integrally provided with a holding body is provided in a recess formed on the back surface of the mounting portion. This can be achieved by projecting in one direction, attaching the pump to the water receiving tank with this bolt, and causing the holding body to abut the wall of the recess of the water receiving tank to prevent the bolt from rotating.
本発明の場合には、ポンプ取付用の外部ナツトを回転さ
せると、保持部が受水槽凹部の内壁面に当接し、それ以
上ボルトが回転することは防止される。In the case of the present invention, when the external nut for mounting the pump is rotated, the holding portion comes into contact with the inner wall surface of the recess of the water receiving tank and further rotation of the bolt is prevented.

けられている。As shown in FIG. 1, the water supply device according to the present invention is a combination of a water receiving tank 2 made of synthetic resin by blow molding and an automatic pump 4. The water receiving tank 2 is provided with a ball tap 6 to which a water pipe is attached, an overflow pipe 8 and a drain port 10.

良好である。The tap water stored in the water receiving tank 2 is supplied and pressurized by the pump 4 to be supplied to the faucet. Here, the upper surface of the water receiving tank 2 is provided with a convex portion extruded from the inner side to the outer side, and serves as a mounting portion 12 of the pump 4. As shown in FIG. 2 which is a sectional view of the mounting portion 12, the mounting bolt 14 has an inner recess 16
The mounting portion 12 is held in a watertight manner by a nut 24 through the packing 20 and the washer 22 so as to project outward from the side through the hole 18. The leg 4A of the pump 4 is on the packing 20.
Is placed and further fixed by the bag nut 30 via the washer 26. A holding body 32 having a U-shaped cross section is fixed to the head 14A of the bolt 14. The dimensional relationship between the holding body 32 and the mounting portion 12 is shown in FIG. 4 as seen from the inner surface side of the water receiving tank 2. A mounting hole 18 is provided at a position eccentric from the center of the mounting portion 12 by 1. From the center of rotation of the bolt 14 to the holder
The distance L to the end of 32 is longer than the distance A to the inner wall 16A closest to the recess 16 formed inside the mounting portion 12 of the water receiving tank 2. Further, in this example, the distance L is made longer than the distance B to the other inner wall 16B. Therefore, when the bag nut 30 is tightened or warmed, even if the bolt 14 slightly rotates, the holding body 32 contacts the inner walls 16A and 16B to prevent the bolt 14 from rotating. Therefore, when the pump 4 is attached to and removed from the water receiving tank 2, it is not necessary to enter the water receiving tank 2 and the bag nut 30 can be easily attached and detached, so that the maintainability is good.
