本発明は、接続された管が動揺するのを防止するために採用する管路連結構造と、前記管路連結構造を採用した給水装置に関するものである。 The present invention relates to a pipe connection structure employed to prevent connected pipes from shaking, and a water supply device employing the pipe connection structure.
上下水道工事に際して使用される仮設配管の管路接続は、連結作業が容易であると共にその分離作業も容易である必要が求められる。この要求に対して、特許文献１に連結対象の一方の管路端に鞘管部を設け、他方の挿入管の先端所定位置に係止突部を設け、鞘管部に前記係止突部の係合機構を内設した管路連結構造が開示されている。前記の係合機構は鞘管部内周面に、係止突部が係合する係合凹条部と係合凹条部の奥方にシール収納凹条部を設けると共に、係合凹条部が開口端に露出して係止突部が進出可能とする切欠部を開口端に形成し、前記シール収納凹条部に所定のリングシールを装着して構成されている。 Pipe connections for temporary piping used in water and sewage works require easy connection work as well as easy separation work. In response to this request, in Patent Document 1, a sheath tube section is provided at one end of the pipe line to be connected, a locking protrusion is provided at a predetermined position at the distal end of the other insertion tube, and the locking protrusion is provided on the sheath tube section. A pipe connection structure is disclosed that includes an internal engagement mechanism. The above-mentioned engagement mechanism is provided with an engagement groove on the inner circumferential surface of the sheath tube portion, an engagement groove with which the locking protrusion engages, and a seal storage groove on the inner side of the engagement groove. A notch is formed at the open end so that the locking protrusion can extend through the open end, and a predetermined ring seal is attached to the seal storage groove.
前記の管路連結構造は、挿入管の係止突部を切欠部から差し入れて係合凹条部の延長上に位置させた後、挿入管を回動させて係止突部を切欠部から移動させると、挿入管の抜け止めがなされると共にリングシールで密封されるので、管接続作業が非常に容易である。 In the pipe connection structure described above, the locking protrusion of the insertion tube is inserted through the notch and positioned on the extension of the engagement groove, and then the insertion tube is rotated to remove the locking protrusion from the notch. When moved, the insertion tube is prevented from coming off and is sealed with a ring seal, making the tube connection work very easy.
また災害時などにおいて、給水車への給水を消火栓など既存給水機構に連結した緊急給水装置が知られている（特許文献２）。前記の緊急給水装置は、既存給水機構に連結して所定の高さまで起立させる起立管部分と、前記起立管部分に連結して横方向に突出して先端に給水口を設けた腕管部分とを備え、起立管部分に給水栓と自由回転連結部を介設し、腕管部分を回動させることで給水車への給水を可能としている。 Moreover, in the event of a disaster, an emergency water supply device is known that connects water supply to a water truck to an existing water supply mechanism such as a fire hydrant (Patent Document 2). The above-mentioned emergency water supply device includes an upright pipe part that is connected to an existing water supply mechanism and erected to a predetermined height, and an arm pipe part that is connected to the upright pipe part and projects laterally and has a water supply port at its tip. A hydrant and a free-rotation connecting part are interposed in the standpipe part, and by rotating the arm pipe part, it is possible to supply water to the water tanker.
特許文献１で開示されているように一方の管端を他方の管端に挿入して回動するだけで連結ができ、また逆操作で分離できる管連結構造は、仮設配管のような使用後に分離するものには最適であるが、着脱操作を容易にするために連結部分には遊びがある。このため例えば特許文献２に開示されているような緊急給水装置の組み立てに前記連結構造を採用すると、遊びのために起立管部分や腕管部分が動揺することがあり、給水作業がスムーズに行われない問題が生ずる。 As disclosed in Patent Document 1, the pipe connection structure that can be connected simply by inserting one pipe end into the other pipe end and rotating, and can be separated by reverse operation, is easy to use after use such as temporary piping. It is ideal for detachable items, but there is some play in the connecting parts to make attachment and detachment easier. For this reason, if the above connection structure is adopted for assembling an emergency water supply device as disclosed in Patent Document 2, for example, the standpipe portion and the arm tube portion may sway due to play, making it difficult to perform water supply work smoothly. Problems that cannot be solved will arise.
そこで本発明は、差込回動という単純な操作で連結される管路連結構造において、連結後の遊びが生じない新規な管路連結構造及び前記管路連結構造を採用した給水装置を提案したものである。 Therefore, the present invention proposes a new pipe connecting structure in which the pipe connecting structure is connected by a simple operation of insertion and rotation, and in which play does not occur after connection, and a water supply device that employs the pipe connecting structure. It is something.

The opening end of the tube section is provided with a notch in which the engagement groove is exposed and the locking protrusion can advance, and the locking protrusion of the insertion part is inserted through the notch to open the engagement groove. In the pipe connection structure in which the connection part is prevented from coming off by being positioned on the extension and relatively rotating around the pipe axis direction, the sheath is attached to the insertion part at the rear position from the locking protrusion. A disc body is fitted with a sealing tongue part that abuts the opening end surface of the pipe part and extends from the notch to the locking groove, and the disc body is inserted so as to be pressable toward the locking protrusion. It is characterized by comprising a pressing cylinder screwed onto the outer periphery of the part.
而して上記の管路連結構造は、係止突部と切欠部の位置を合わせて挿入部を鞘管部内に挿入し、管軸方向を中心とした相対的回動で係止突部を係合凹条内に位置させ、封止舌片部を切欠部から差し入れて円板体を鞘管部の開口端に当接し、押圧筒体を回転して円板体を強圧すると、係止突部が係止凹条部内の開口側に強く押し付けられ、管路の連結部分は遊び状態が無く、堅牢に連結されることになる。 In the above-mentioned pipe connection structure, the insertion part is inserted into the sheath tube by aligning the positions of the locking protrusion and the notch, and the locking protrusion is rotated relative to the tube axis direction. Position it in the engagement groove, insert the sealing tongue part through the notch, bring the disc body into contact with the open end of the sheath tube part, and rotate the pressing cylinder to strongly press the disc body to lock it. The protrusion is strongly pressed against the opening side of the locking groove, and the connecting portion of the conduit is firmly connected without any play.
本発明に係る給水装置は、適宜な給水源との連結部を設け、開閉脚（三脚又は四脚等）を付設して起立可能とした給水源用管路と、開閉弁及び管軸方向を中心として自由回転可能とした回転連結部を介設した操作用管路と、エルボ管路と、給水口を備えた給水管路を連繋して所定高さに給水口が位置する管路構成として、各管路の管端に前記した鞘管部と、円板体及び押圧筒体を付設した挿入管部を溶着したものである。 The water supply device according to the present invention is provided with a connection part with an appropriate water supply source, a water supply pipe line that can be erected by attaching opening/closing legs (tripods, quadrupeds, etc.), an opening/closing valve, and a pipe axis direction.
