【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、特にブロー成形などで成形さ
れる合成樹脂製受水槽を備えた給水装置の改良に関す
る。Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water supply device, and more particularly to improvement of a water supply device provided with a synthetic resin water receiving tank formed by blow molding or the like.
従来の受水槽付き給水装置は、特開昭60−230592号のよ

え、受水槽内に垂下した吸込管を介して貯水をポンプで
汲み上げ、水栓に加圧給水するものである。Some conventional water supply devices with a water receiving tank have a pump mounted on the upper surface of the water receiving tank, as in JP-A-60-230592. When the tap water pressure is low, the tap water is stored in a one-piece water receiving tank, and the stored water is pumped through a suction pipe hanging in the water receiving tank to supply water under pressure to a faucet.

の寸法関係も、ポンプヘツド構成部品が複数のため、そ
れだけ寸法誤差も集積されて大きくなつている。The conventional water supply device described above has a difficulty in assembling because it does not take into consideration the molding size of the water receiving tank and the size variation of the suction pipe. That is, when the water receiving tank is made of synthetic resin, the pitch between the suction pipe through hole and the pump mounting bolt hole tends to vary because the water receiving tank is large and thin and hollow. In addition, the dimensional relationship between the suction pipe mounting port of the pump and the pressure tank of the pump is large due to the accumulation of dimensional errors due to the plurality of pump head constituent parts.
さらに、吸込管にも水平方向の横引き部があり、水平方

大の要因となつている。従つて、ポンプと受水槽とを組

ていた。このような方法では、組立性に難点があるばか
りでなく、吸込管の貫通穴から雨滴が浸入するのを防止
するパツキンの密封性にも悪影響を及ぼすことになる。Further, the suction pipe also has a horizontal horizontal pulling portion, and in addition to the dimensional error in the horizontal direction, the inclination of the hanging portion also causes the error in the mounting dimension to increase. Therefore, when combining the pump and the receiving tank, if the pump is first fixed to the receiving tank,
It is difficult to match the position of the water tank's hole that penetrates the suction pipe with the position of the hanging part of the suction pipe. Therefore, conventionally, the suction pipe is first penetrated through the water receiving tank, and then the pump is gradually moved in accordance with the position of the suction pipe to be mounted at an appropriate position. Further, as another method, a method with poor workability has been performed, in which the laterally drawn portion of the suction pipe is cut at appropriate times to perform alignment. Such a method not only has a difficulty in assembling, but also adversely affects the sealing property of the packing that prevents raindrops from entering through the through hole of the suction pipe.
本発明は、上記の従来技術の欠点を改良し、組立性と雨
滴密封性の良好なる受水槽付き給水装置を提供すること
を目的とする。SUMMARY OF THE INVENTION It is an object of the present invention to improve the above-mentioned drawbacks of the prior art and to provide a water supply device with a water receiving tank, which is excellent in assemblability and raindrop sealing property.

成される。The purpose is to mount and fix the pump on the upper surface of the water receiving tank made of synthetic resin, hang down the suction pipe of the pump through an opening provided on the upper surface of the water receiving tank, and to the opening is larger than the outer diameter of the suction pipe. An annular packing made of an elastic body having an inner diameter is attached, and an annular body having an inner diameter larger than the outer diameter of the suction pipe is press-fitted into the inner circumference of the packing, and the space between the upper portion of the ring body and the outer circumference of the suction pipe. This is achieved by closely attaching an elastic cover to the.
上記の構造により、ポンプと受水槽との寸法関係のばら
つきを比較的余裕をもつて吸収することができる。With the above structure, it is possible to absorb the variation in the dimensional relationship between the pump and the water receiving tank with a relatively large margin.
従つて、先にポンプを受水槽に固定し、次いで吸込管を

侵入は防げる。Therefore, first fix the pump to the water receiving tank, then hang the suction pipe into the water receiving tank and then connect it to the pump.Finally, assemble the sealing structure between the through hole of the water receiving tank and the suction pipe. Assembling workability is good because it is sufficient. Further, since the through hole of the suction pipe can be opened at an arbitrary position of the water receiving tank, an appropriate structure can be formed in consideration of the position of the suction port of the pump, stress distribution, and the like. Further, even if the center position of the suction pipe and the hole of the water receiving tank deviates from each other, the sealing property of the hole of the water receiving tank is kept good, so that the entry of raindrops can be prevented.
従つて、組立性と密封性の良好な給水装置が得られる。Therefore, a water supply device having good assembling property and sealing property can be obtained.
以下、本発明の一実施例を、第１図ないし第４図により

緩衝され、中空の受水槽２と共鳴することは無くなる。In addition, considering the formation of the mounting portion 2A of the pump 4, the handle portion 2C, and the vertical groove portion 2D for weight resistance, the center of the split surface of the mold of the water tank 2
The vertical surface including 11 is used as a horizontal split mold system. As shown in FIG. 2, by pushing out a part of the upper surface of the water receiving tank 4,
A mounting portion 2A of the pump 4 is provided, a bolt 14 is projected from the inside through the hole 12, and the cushion 16 is watertightly held and fixed by the nut 20 via the washer 18. This cushion 16
The leg portion 4A of the pump 4 is placed on the upper portion, and the bag nut 24 is tightened and fixed via the washer 22. Therefore, the water-sealing action of the cushion 16 prevents raindrops from entering the water receiving tank 2 through the holes 12. Further, the vibration of the pump 4 is also buffered by the cushion 16 and does not resonate with the hollow water receiving tank 2.

Attach the suction ring 8 to the hole 2B in a watertight manner. Here, this mounting state will be described with reference to FIG. First, the hole 2B of the water receiving tank 2
Then, attach the bush 26. Ring projection 26A of bush 26
The outer diameter of is slightly larger than the inner diameter of hole 2B.
The entire bush 26 is slightly contracted inward when attached to the. Next, when the synthetic resin ring body 28 is press-fitted into the bush 26, the bush 26 expands outward and the annular protrusion 26A
Keeps watertightness by crimping to the inner circumference of hole 2A. Next, the suction pipe 8 to which the cover 30 is attached in advance is hung through the ring body 28 into the water receiving tank 2. The flange portion 25 of the suction pipe 8 is attached to the suction port of the pump 2. Here, rather than the inner diameter of the ring 28,
Since the inner diameter of the lower end edge portion 26B of the bush 26 is made small, the propagation and resonance of the vibration sound of the pump 2 due to the suction pipe 8 hitting the ring body 28 can be prevented. This bush 26 and ring 28
The inner diameter of is larger than the outer diameter of the suction pipe 8 so that a gap 32 is formed. This gap is determined in consideration of the displacement of the mounting position of the pump 2, the dimensional error of the laterally drawn portion 8A of the suction pipe 8, the molding dimensional error of the water receiving tank 2, and the like. Then
The lower end edge portion 30A of the cover 30 is attached to the upper end portion of the ring body 28. The lower edge 30A and the upper edge 30B of this cover 30 are
The dimensions are such that they closely contact the ring body 28 and the suction pipe 8 with a tight margin, and keep the airtightness to prevent raindrops from entering.
