Description
【０００１】[0001]
この考案は、エアーチューブ接続用の管継手に関するものである。 This invention relates to a pipe joint for connecting an air tube.
【０００２】[0002]
エアーチューブ接続用の管継手としては、例えば、図３に示されるようなもの があり、このものは同図に示すように、弾性合成樹脂で構成された筒状の主体１ と、この主体１の一端に具備させたチューブ接続部２と、主体１の他端に具備さ せた取付体３とから構成されている。 As a pipe joint for connecting an air tube, for example, there is a pipe joint shown in FIG. 3, which is a tubular main body 1 made of an elastic synthetic resin and a main body 1 as shown in FIG. Of the main body 1 and a mounting body 3 provided at the other end of the main body 1.
【０００３】 上記した取付体３は、図３に示すように、他部より大径の工具対応部３０を有 した筒状のもので、一端に取付用ネジ部３１を形成すると共に他端側周面に係止 片３２を設けてある。As shown in FIG. 3, the above-mentioned mounting body 3 is a tubular one having a tool corresponding portion 30 having a diameter larger than that of the other portion, and has a mounting screw portion 31 formed at one end and the other end side. A locking piece 32 is provided on the peripheral surface.
【０００４】 このものは、取付体３における係止片３２側部分にＯリングを外装した状態で 、この端部側を主体１の開口端から圧入するようにして取り付ける。この取付け 状態では、係止片３の主体１への食込みにより、取付体３は主体１に対して抜止 め状態となっており、又、Ｏリングの存在により主体１と取付体３との間の気密 性は確保されている。In this case, the O-ring is mounted on the portion of the mounting body 3 on the side of the locking piece 32, and the end portion side is press-fitted from the opening end of the main body 1. In this mounted state, the mounting body 3 is prevented from coming out of the main body 1 by the biting of the locking piece 3 into the main body 1, and the presence of the O-ring causes the space between the main body 1 and the mounting body 3 to be prevented. The airtightness of is secured.
【０００５】 そして、近年、エレクトロニクス産業界で使用される装置において、小径のチ ューブを接続する為の小型の管継手が要望され、上記管継手の構成をそのまま採 用、即ち、相似的縮小したものが製作されている。In recent years, in devices used in the electronics industry, a small pipe joint for connecting a tube having a small diameter has been demanded, and the structure of the pipe joint is directly adopted, that is, reduced in size. Things are being manufactured.
【０００６】 ところが、上記のものでは、主体１側に例えば、チューブ接続部２側に下方に 向く外力が作用すると、図４に示す如く、取付体３が圧入されている主体１部分 （特に開放端部）が変形し、主体１の内周面と取付体３の外周面との間に同図に 示す如く間隙ｇができてしまう。この現象は、場合によってはＯリングの機能低 下による流体漏れを招来する。However, in the above-mentioned one, when an external force directed downward is applied to the main body 1 side, for example, to the tube connection portion 2 side, as shown in FIG. The end) is deformed, and a gap g is formed between the inner peripheral surface of the main body 1 and the outer peripheral surface of the mounting body 3 as shown in FIG. This phenomenon may lead to fluid leakage due to the functional deterioration of the O-ring.
【０００７】 尚、主体１における取付体３の圧入部分の肉厚を大きくするか、又は、前記部 分の長さを大きくすると上記問題は解決できるが、全体の形状を可能な限り小さ くしたいことからこの案は採用できない。The above problem can be solved by increasing the thickness of the press-fitted portion of the mounting body 3 in the main body 1 or by increasing the length of the above-mentioned portion, but it is desirable to make the overall shape as small as possible. Therefore, this plan cannot be adopted.
【０００８】[0008]
そこで、この出願の考案では、小型であり、外力が作用した場合でも主体 と取付体との間の気密性が確保される管継手を提供することを課題とする。 Therefore, it is an object of the invention of this application to provide a pipe joint that is small in size and ensures airtightness between the main body and the mounting body even when an external force is applied.
【０００９】[0009]
この考案では、弾性合成樹脂で構成された筒状の主体１と、拡大径部３３を有 し且つ前記主体１への挿入部側外周壁に係止片３２を有する筒状の取付体３とを 具備し、前記主体１の開放端に取付体３の挿入部側を圧入して構成された管継手 に於いて、主体１の開放端に環状薄肉片１０を延長させると共に、拡大径部３３ に前記環状薄肉片１０と対応する環状溝３４を形成し、前記環状薄肉片１０を環 状溝３４に圧入させ、取付体３における係止片３２と環状薄肉片１０との間の外 周壁と、主体１の内周壁との間にシールリングを介装してあり、前記環状溝３４ を、溝底面に向かって拡大径又は縮小径となる構成としている。 In this invention, a tubular main body 1 made of an elastic synthetic resin, a tubular mounting body 3 having an enlarged diameter portion 33 and a locking piece 32 on an outer peripheral wall of the main body 1 on the side of an insertion portion are provided. In a pipe joint comprising the main body 1 and the insertion end of the attachment body 3 press-fitted into the open end of the main body 1, the annular thin piece 10 is extended to the open end of the main body 1, and the enlarged diameter portion 33 is formed. An annular groove 34 corresponding to the annular thin piece 10 is formed in the annular thin piece 10, and the annular thin piece 10 is press-fitted into the annular groove 34, and an outer peripheral wall between the locking piece 32 and the annular thin piece 10 in the mounting body 3 is formed. A seal ring is interposed between the inner peripheral wall of the main body 1 and the annular groove 34 has an enlarged diameter or a reduced diameter toward the groove bottom surface.
【００１０】 この出願の考案は次の作用を奏する。 この管継手では、係止片３２と主体１の内周壁との係止により、また、環 状薄肉片１０と環状溝３４の構成壁との係止により、主体１は取付体３に対して 二箇所で且つ全周で支持された状態となっている。そして主体１と取付体３との 間は前記二箇所で支持された部分相互間に装着されたシールリングにより気密性 が確保された状態となっている。ここで、上記とで係止されている範囲の主 体１部分は前記両者の係止より変形が抑制されるものとなっている。したがって 、たとえ、チューブ接続部側に外力（図１参照）が作用したとしても、上記と で係止されている範囲内に位置するシールリングは主体１の内周壁と取付体３ の挿入部外周壁により全周でほぼ均等圧で挟圧された状態は維持され、シールリ ングによる主体１の内周壁と取付体３の挿入部外周壁相互間の気密性は確保され ることになる。The invention of this application has the following effects. In this pipe joint, the main body 1 is attached to the mounting body 3 by the engagement between the engagement piece 32 and the inner peripheral wall of the main body 1 and the engagement between the annular thin piece 10 and the constituent wall of the annular groove 34. It is supported in two places and all around. The airtightness is ensured between the main body 1 and the mounting body 3 by the seal ring mounted between the portions supported at the two locations. Here, the deformation of the main body 1 portion in the range locked by the above is suppressed more than the locking of the both. Therefore, even if an external force (see FIG. 1) is applied to the tube connecting portion side, the seal ring located within the range locked by the above is the inner peripheral wall of the main body 1 and the outer peripheral portion of the insertion portion of the mounting body 3. The condition that the wall is clamped by the wall with a substantially uniform pressure is maintained, and the airtightness between the inner peripheral wall of the main body 1 and the outer peripheral wall of the insertion portion of the mounting body 3 is secured by the sealing ring.
【００１１】[0011]
以下、この出願の考案の実施の形態を図面に従って説明する。 Embodiments of the invention of this application will be described below with reference to the drawings.
【００１２】 この実施例の管継手は、基本的には従来の技術の欄に記載したものと同様の構 成であり、図１に示すように、弾性合成樹脂で構成されたＬ型筒状の主体１と、 この主体１の一端に具備させたチューブ接続部２と、主体１の他端に具備させた 取付体３とから構成されている。The pipe joint of this embodiment basically has the same structure as that described in the section of the prior art, and as shown in FIG. 1, is an L-shaped tubular member made of elastic synthetic resin. The main body 1 of the main body 1, the tube connecting portion 2 provided at one end of the main body 1, and the mounting body 3 provided at the other end of the main body 1.
【００１３】 主体１は、図１及び図２に示すように、一つの開放端に環状薄肉片１０を延長 させてあると共に、この環状薄肉片１０の直径を主体１の外径よりも少し小さく 設定してある。As shown in FIGS. 1 and 2, the main body 1 has an annular thin piece 10 extended to one open end, and the diameter of the annular thin piece 10 is slightly smaller than the outer diameter of the main body 1. It is set.
【００１４】 上記チューブ接続部２としては、同図に示すように、押込筒２０を進退させて 環状爪２１によりチューブを脱着させる形式の公知のものを採用してある。As the tube connecting portion 2, as shown in the figure, a known type in which the pushing cylinder 20 is advanced and retracted and the tube is attached and detached by the annular claw 21 is adopted.
【００１５】 上記した取付体３は、図１及び図２に示すように、拡大径部３３と対応する工 具対応部３０を有した筒状のもので、一端に取付用ネジ部３１を形成すると共に 他端側周面に係止片３２を設けてある。そして、上記工具対応部３０の係止片３ ２形成側面に、上記環状薄肉弁１０を圧入する為の環状溝３４（溝幅を環状薄肉 片１０の肉厚と同一又は少し小さく設定してある）を形成している。As shown in FIGS. 1 and 2, the above-mentioned mounting body 3 is a tubular one having a tool corresponding portion 30 corresponding to the enlarged diameter portion 33, and a mounting screw portion 31 is formed at one end thereof. In addition, a locking piece 32 is provided on the peripheral surface on the other end side. An annular groove 34 (the groove width is set to be the same as or slightly smaller than the thickness of the annular thin piece 10 for press-fitting the annular thin valve 10 on the side surface of the tool corresponding portion 30 where the engaging piece 32 is formed. ) Is formed.
【００１６】 このものは、取付体３における係止片３２側部分にＯリング４を外装した状態 で、この端部側を主体１の開口端から圧入すると共に環状薄肉片１０を環状溝３ ４に圧入するようにして取りつける。この状態では、図１に示すように、係止片 ３２の主体１への食込みにより、取付体３は主体１に対して抜止め状態となって おり、又、Ｏリングの存在により主体１と取付体３との間の気密性は確保されて いる。なお、この実施例では図１に示すように、Ｏリング４は取付体３における 係止片３２と環状薄肉片１０との間の外周壁と、主体１の内周壁との間に介装し てある。そして、この実施例の管継手では、図１に示すような外力Ｆが主体１等 に作用した場合、主体１の環状薄肉片１０の内周面や外周面が取付体３の環状溝 ３４構成壁面に当接することとなり、これにより、主体１の開放端全周が取付体 ３によって支持された状態となる。This is a state in which the O-ring 4 is externally mounted on the locking piece 32 side portion of the mounting body 3, and this end side is press-fitted from the open end of the main body 1 and the annular thin piece 10 is inserted into the annular groove 34. Install by pressing into. In this state, as shown in FIG. 1, the mounting body 3 is in a state of being prevented from being pulled out from the main body 1 by the biting of the locking piece 32 into the main body 1. Airtightness with the mounting body 3 is ensured. In this embodiment, as shown in FIG. 1, the O-ring 4 is interposed between the outer peripheral wall between the locking piece 32 and the annular thin piece 10 of the mounting body 3 and the inner peripheral wall of the main body 1. There is. In the pipe joint of this embodiment, when the external force F as shown in FIG. 1 acts on the main body 1 or the like, the inner peripheral surface or the outer peripheral surface of the annular thin piece 10 of the main body 1 has the annular groove 34 configuration of the mounting body 3. It comes into contact with the wall surface, whereby the entire circumference of the open end of the main body 1 is supported by the mounting body 3.
【００１７】 したがって、この管継手では、主体１における取付体３の圧入部分の肉厚が小 さく且つそれの長さが小さいものであったとしても、外力Ｆにより係止片３２と 主体１の内周壁との係止部と、環状薄肉片１０と環状溝３４の構成壁との係止部 との間は変形しにくいものとなり、その結果、Ｏリング４の機能が低下するよう なことは少なくなる。Therefore, in this pipe joint, even if the press-fitted portion of the attachment body 3 in the main body 1 has a small thickness and a small length, the external force F causes the engagement piece 32 and the main body 1 to be separated from each other. The engagement between the inner peripheral wall and the engagement between the thin annular piece 10 and the wall forming the annular groove 34 is less likely to be deformed, and as a result, the function of the O-ring 4 may deteriorate. Less.
【００１８】 なお、上記実施例では、環状溝３４の溝幅を環状薄肉片１０の肉厚と同一又は 僅かに小さく設定したが、少し大きく設定することもできる。In the above embodiment, the groove width of the annular groove 34 is set to be the same as or slightly smaller than the thickness of the annular thin piece 10, but it may be set to be slightly larger.
【００１９】 また、上記実施例で示した環状溝３４を、溝底面に向かって拡大径、又は、縮 小径となるものとしてもよく、この構成を採用した場合においても、上記変形防 止機能が向上すると共に抜止機能について優れたものとなる。Further, the annular groove 34 shown in the above embodiment may have an enlarged diameter or a reduced diameter toward the groove bottom surface. Even when this configuration is adopted, the deformation preventing function is It will be improved and the retaining function will be excellent.
【００２０】 更に、上記実施例では、主体１をＬ字状のものとしたが、これに限定されるこ となく、Ｔ字、Ｙ字等の形状のものを採用してもよい。Further, although the main body 1 is L-shaped in the above embodiment, the main body 1 is not limited to this and may be T-shaped, Y-shaped or the like.
