Description

本発明は、給湯器の内部等において使用される接続管同士の接続部に装着されて抜け止めに用いられるクリップに対して、接続部からの脱落を防止するために前記クリップに装着される係止片に関するものである。   The present invention relates to a clip that is attached to a connection part of connection pipes used in the interior of a water heater or the like and is attached to the clip in order to prevent the clip from being detached from the connection part. It is about a stop piece.

接続管同士を接続して連結する場合、図7及び図8に示されるように各接続管100,200の端部にフランジ部101,201をそれぞれ設けて接続部300を形成し、この接続部300にクリップ400を嵌合することでワンタッチに接続することが行われている。このクリップ400は、図9に示されるように、一枚の帯状の金属部材を折曲形成することで、中央に形成された管挿通部401と、接続部300へ装着するための開口部402を形成するための開口片403、404と、クリップ両側面に形成されて各接続管100,200のフランジ部101,201が嵌合される窓部405,406とを有して構成され、全体として弾性を有している。   When connecting and connecting the connecting pipes, as shown in FIGS. 7 and 8, flanges 101 and 201 are provided at the ends of the connecting pipes 100 and 200 to form the connecting part 300, and this connecting part One-touch connection is performed by fitting a clip 400 to 300. As shown in FIG. 9, the clip 400 is formed by bending a single band-shaped metal member, so that a tube insertion portion 401 formed in the center and an opening 402 for mounting to the connection portion 300 are formed. Are formed with opening pieces 403 and 404 and window portions 405 and 406 that are formed on both side surfaces of the clip and into which the flange portions 101 and 201 of the connection pipes 100 and 200 are fitted. It has elasticity.

すなわち、クリップ400を使用して接続管同士を接続する場合、接続管同士のフランジ部101,201を当接させるとともに、一方の接続管100の先端部102を相手の接続管200へ内嵌して接合する。なお、両接続管間のシールは、接続管100の先端部102に外嵌装着したOリング103によって行われる。
次に、クリップ400を準備し、その開口部402側から接続管100,200の接続部300を跨ぐように、前記フランジ101及びフランジ部201の一部が窓部405,406に嵌合するように装着することで、接続管同士の抜け止めが行われる。
That is, when connecting the connecting pipes using the clip 400, the flange portions 101, 201 of the connecting pipes are brought into contact with each other, and the tip 102 of one of the connecting pipes 100 is fitted into the mating connecting pipe 200. And join. The sealing between both connecting pipes is performed by an O-ring 103 that is externally fitted to the distal end portion 102 of the connecting pipe 100.
Next, the clip 400 is prepared, and the flange 101 and a part of the flange part 201 are fitted to the window parts 405 and 406 so as to straddle the connection part 300 of the connection pipes 100 and 200 from the opening 402 side. By attaching to the connecting pipe, the connection pipes are prevented from coming off.

ところが、上記クリップ400を使用した接続構造によれば、クリップ400に対して図の下側方向(開口部402の方向)から外部力が加わると、クリップ400が容易に脱落する場合があった。このような脱落があると、接続管同士の連結が外れるので、接続管内の流体が漏出するという事態に陥る。   However, according to the connection structure using the clip 400, when an external force is applied to the clip 400 from the lower side of the drawing (the direction of the opening 402), the clip 400 may easily fall off. If such a drop occurs, the connection pipes are disconnected from each other, so that the fluid in the connection pipe leaks.

そこで、接続管同士の接続部300へのクリップ400の固定を確実にするため、クリップ400の開口部側に装着される管接続用クリップの抜止カバー500が提案されている(特許文献1)。
特開平8−28770
Then, in order to ensure the fixation of the clip 400 to the connection part 300 between connection pipes, a retaining cover 500 for a pipe connection clip mounted on the opening side of the clip 400 has been proposed (Patent Document 1).
JP-A-8-28770

この抜止カバー500は、図8に点線で示されるように、クリップ400の開口部402側に位置する開口片403,404同士を跨ぐ位置に形成されたカバー本体部501と、該カバー本体部501の両端に形成されて開口片同士が外へ開かないように開口片の外側面に接合する拡開防止壁502、502と、カバー本体部501の中央位置に設けられ接合部300のフランジ部の外周面に接合する当接部503を具備して構成されている。   As shown by a dotted line in FIG. 8, the retaining cover 500 includes a cover body 501 formed at a position straddling the opening pieces 403 and 404 located on the opening 402 side of the clip 400, and the cover body 501. Of the flange portion of the joint portion 300 provided at the center position of the cover body portion 501 and the spread prevention walls 502 and 502 which are formed at both ends of the cover body and are joined to the outer surface of the opening pieces so that the opening pieces do not open to the outside. An abutting portion 503 joined to the outer peripheral surface is provided.

上記構造の抜止カバー500をクリップ400に使用した場合、開口片403,404に跨って開口片同士が開かないように装着されるため、クリップ400の開口片同士が開拡することがなくクリップ400の接続部300からの脱落を防止することができる。   When the retaining cover 500 having the above-described structure is used for the clip 400, the clip 400 is mounted so that the opening pieces do not open across the opening pieces 403 and 404, so that the opening pieces of the clip 400 do not spread. Can be prevented from falling off from the connecting portion 300.

しかしながら、上記構造の抜止カバー500によれば、接続部300にクリップ400を装着した後に開口片403,404を跨ぐように装着する作業が必要となるので作業工程が増加して煩雑であるという問題点があった。特に、抜止カバー500はクリップ400とは別部品となるため、クリップとは別に個数などを管理する必要も生じる。   However, according to the retaining cover 500 having the above-described structure, it is necessary to perform the mounting operation so as to straddle the opening pieces 403 and 404 after the clip 400 is mounted on the connecting portion 300, and thus the work process is increased and complicated. There was a point. In particular, since the retaining cover 500 is a separate component from the clip 400, it is necessary to manage the number and the like separately from the clip.

本発明は上記実情に鑑みてなされたもので、接続管同士の接続部に装着されるクリップに対する抜止用の係止片であって、接続部への装着前後を通じてクリップに一体的に固定でき、装着作業工程を増加させない係止片の構造を提供することを目的としている。   The present invention has been made in view of the above circumstances, and is a locking piece for retaining the clip attached to the connecting portion between the connecting pipes, and can be integrally fixed to the clip through before and after being attached to the connecting portion, An object of the present invention is to provide a structure of a locking piece that does not increase the mounting work process.
