Description
【０００１】[0001]
本考案は管継手に関し、詳しくは、食品、医療、塗料生産設備等の分野に用い られ、分解や洗浄等を容易に行い得る管継手に関する。 The present invention relates to a pipe joint, and more particularly to a pipe joint which is used in the fields of food, medical treatment, paint production equipment and the like and which can be easily disassembled and washed.
【０００２】[0002]
これらのサニタリー分野に用いられる配管設備は、常に清潔にしておかなけれ ばならないため、分解、洗浄、組立てが容易な構造であると共に、流体物の滞留 を防ぐためパイプなどの接続部の流路内に流体が滞留しない構造である必要があ った。 一般に、これらの分野の継手として、サニタリーパイプの端部にフェルールを 溶接若しくは螺合し、さらに、対向する一対のフェルールの接合面にガスケット 等を挟むと共に、クランプで両フェルールを圧接するサニタリー継手が用いられ ている。 しかしながら、これらのサニタリー継手は、パイプの軸心を正確に合わせるた めフェルールの接合を正確に行う必要があり、パイプの接続が面倒であり、熟練 者による作業も必要としていた。 Since the piping equipment used in these sanitary fields must be kept clean at all times, it has a structure that is easy to disassemble, clean, and assemble, and to prevent the accumulation of fluids inside the flow path of the connection part such as a pipe. It was necessary to have a structure in which the fluid did not stay in. In general, as a joint in these fields, there is a sanitary joint in which a ferrule is welded or screwed to the end of a sanitary pipe, a gasket or the like is sandwiched between the mating faces of a pair of opposing ferrules, and both ferrules are pressed together by a clamp. It is used. However, in these sanitary joints, it was necessary to join the ferrules accurately in order to accurately align the axial center of the pipe, the pipe connection was troublesome, and the work of a skilled worker was also necessary.
【０００３】 一方、ソケット本体とプラグ本体とからなる管継手の構造は、ソケット本体の プラグ挿入口近傍にテーパ孔を形成し、各テーパ孔に施錠部材である施錠ボール を設け、さらに、この施錠ボールをロック或いは解除するためのスリーブをプラ グ挿入口近傍に付勢ばねを介して摺動可能に装着し、プラグ本体の胴部には、こ の施錠ボールが係合する施錠溝が形成されたものである。On the other hand, in the structure of the pipe joint composed of the socket body and the plug body, a tapered hole is formed in the vicinity of the plug insertion port of the socket body, and each tapered hole is provided with a locking ball as a locking member. A sleeve for locking or unlocking the ball is slidably mounted near the plug insertion opening via a biasing spring, and a locking groove with which the locking ball engages is formed in the body of the plug body. It is a thing.
【０００４】 そして、ソケット本体にプラグ本体を挿入すると、ソケット本体のスリーブは 施錠ボールの遠心方向への移動を規制して、プラグ本体の施錠溝に係合するので 、双方がロックされ、使用に供される状態となる。また、ソケット本体のスリー ブを摺動させると、ソケット本体に設けられた施錠ボールは遠心方向に移動可能 となって、プラグ本体の施錠溝からの係合が解かれてロックが解除される。When the plug body is inserted into the socket body, the sleeve of the socket body restricts the movement of the locking ball in the centrifugal direction and engages with the locking groove of the plug body, so that both are locked and ready for use. It is ready to be served. Further, when the sleeve of the socket body is slid, the locking ball provided on the socket body can move in the centrifugal direction, the engagement with the locking groove of the plug body is released, and the lock is released.
【０００５】[0005]
しかし、この種の管継手は、分解、洗浄、組立てが困難であるため、衛生面に おいて洗浄が重要となるサニタリー分野等には不向きであった。 そこで、本考案は、このような従来における各種の継手による課題に鑑みて開 発されたものであり、施錠構造による管継手をサニタリー分野に用いることがで きる特有の構造を有した管継手を提供することを目的とする。 However, this type of pipe joint is difficult to disassemble, clean and assemble, so it was not suitable for sanitary fields where cleaning is important from a hygiene standpoint. Therefore, the present invention was developed in view of the problems caused by such various conventional joints, and a pipe joint having a unique structure that can be used in the sanitary field is a pipe joint having a locking structure. The purpose is to provide.
【０００６】[0006]
上記の目的を達成するために、本考案は、分離可能に設けた一対のパイプの接 続端部に跨って施錠筒体を設け、この施錠筒体には、一対のパイプの端部近傍位 置を施錠する施錠機構をそれぞれ取付けると共に、この施錠筒体を一対のパイプ の長さ方向に沿って移動自在に設け、かつ施錠筒体を一対のパイプの何れか一方 側に移動させたときパイプの接続部位が施錠筒体より露出するような構成を採用 した。 In order to achieve the above-mentioned object, the present invention provides a locking cylinder over the connecting ends of a pair of separable pipes, and the locking cylinder has a position near the ends of the pair of pipes. A locking mechanism for locking the lock is installed, and the locking cylinder is movably provided along the length direction of the pair of pipes, and when the locking cylinder is moved to one side of the pair of pipes, the pipe is moved. We adopted a structure in which the connection part of is exposed from the locking cylinder.
【０００７】 また、一対のパイプの接続部位の構造は、雄パイプの端部の外径を縮径した縮 径段部と雌パイプの端部の内径を拡径した拡径段部とをＯリングを介して接続嵌 合するインロー構造が好ましい。In addition, the structure of the connecting portion of the pair of pipes has a reduced diameter step portion in which the outer diameter of the end portion of the male pipe is reduced and an enlarged diameter step portion in which the inner diameter of the end portion of the female pipe is increased. A spigot structure that is connected and fitted via a ring is preferable.
【０００８】 一対のパイプの接続端部に跨って施錠する施錠筒体の施錠機構は、双方のパイ プの端部近傍位置の外周面に、少なくとも一本の施錠溝を形成し、このパイプの 外周面を摺動する施錠筒体に形成したテーパ孔に施錠ボールを装着すると共に、 前記施錠筒体の外周面にバネを介して摺動するスリーブにより前記施錠溝に係合 する施錠ボールを出没自在に設けた構造を選択するのが良い。The locking mechanism of the locking cylinder that locks over the connecting ends of a pair of pipes has at least one locking groove formed on the outer peripheral surface near the ends of both pipes. A locking ball is mounted in a tapered hole formed in the locking cylinder that slides on the outer peripheral surface, and a locking ball that engages with the locking groove is inserted and retracted by a sleeve that slides on the outer peripheral surface of the locking cylinder via a spring. It is better to select a structure that is freely provided.
【０００９】[0009]
本考案は上記のように構成したので、施錠筒体に設けられた施錠部材である施 錠ボールを各パイプに形成した施錠溝に係合させて一対のパイプを接続すること ができ、また、一対のパイプを分離するときは、施錠筒体を何れか一方のパイプ に移動し退避させることができるので、パイプの分離、接続が容易であると共に 、一対のパイプの嵌合端部がそれぞれ露出するので洗浄も容易に行える。 Since the present invention is configured as described above, it is possible to connect a pair of pipes by engaging a locking ball, which is a locking member provided in the locking cylinder, with a locking groove formed in each pipe. When separating a pair of pipes, the locking cylinder can be moved to one of the pipes and retracted, so that the pipes can be easily separated and connected, and the fitting ends of the pair of pipes are exposed. Therefore, cleaning can be easily performed.
【００１０】 さらに、前記一対のパイプを接続した時の施錠溝の間隔と同間隔に離間した施 錠筒体の円周部分に前記施錠部材を複数配設しているので、１つの施錠筒体によ って一対のパイプを接続することができる。Further, since a plurality of the locking members are arranged in the circumferential portion of the locking cylinder which is spaced at the same interval as the interval between the locking grooves when the pair of pipes are connected, one locking cylinder is provided. With this, a pair of pipes can be connected.
【００１１】 施錠筒体に装着されたスリーブは、バネで施錠部材である施錠ボールを規制す る位置に付勢され、スリーブに設けられた規制部で施錠ボールの遠心方向への移 動を規制し、施錠筒体と一対のパイプとをロックする。A sleeve mounted on the locking cylinder is biased by a spring to a position that restricts a locking ball that is a locking member, and a restricting portion provided on the sleeve restricts the movement of the locking ball in the centrifugal direction. Then, the locking cylinder and the pair of pipes are locked.
【００１２】 また、一対のパイプを分離する場合、スリーブの逃げ部が施錠ボール上に位置 するように、バネの弾発力に抗してスリーブを移動させる。この状態で、施錠筒 体を何れか一方のパイプ側に移動させると、施錠ボールは、パイプの施錠溝に沿 って遠周方向に押されて施錠溝から飛び出し、スリーブの逃げ部とパイプ外周面 との間隙に入り込んでスリーブを規制するので、スリーブがバネの弾発力に抗し てこの位置に保持される。そして、一方のパイプに施錠筒体を退避させ、他方の パイプを分離する。Further, when separating the pair of pipes, the sleeve is moved against the elastic force of the spring so that the escape portion of the sleeve is located on the locking ball. When the locking cylinder is moved to one of the pipes in this state, the locking ball is pushed in the distal direction along the locking groove of the pipe and jumps out of the locking groove, and the escape portion of the sleeve and the outer circumference of the pipe. The sleeve is held in this position against the elastic force of the spring because it enters the gap with the surface and regulates the sleeve. Then, the locking cylinder is retracted to one pipe and the other pipe is separated.
【００１３】 さらに、一対のパイプを接続する場合、施錠筒体を嵌合した一対のパイプの嵌 合部分上に移動させ、施錠ボールを各パイプの施錠溝に係合させる。この時、ス リーブを係止していた施錠ボールが内径方向に移動してスリーブの規制を解除す るため、バネで付勢されているスリーブは、施錠ボールを規制する位置に弾発復 帰し、スリーブの規制部が施錠ボールの遠心方向への移動を規制し、施錠筒体と 一対のパイプとをロックする。Further, when connecting the pair of pipes, the locking cylinder is moved onto the fitting portion of the pair of fitted pipes, and the locking ball is engaged with the locking groove of each pipe. At this time, the locking ball that locked the sleeve moves in the inner diameter direction to release the restriction of the sleeve, so the sleeve that is biased by the spring springs back to the position that restricts the locking ball. The restricting portion of the sleeve restricts the movement of the locking ball in the centrifugal direction, and locks the locking cylinder and the pair of pipes.

【００１８】 そして、施錠筒体６の両端外周面には、施錠筒体６の中央円周部分に形成され た係止段部７の突部７ａと施錠筒体６の両端部に取り付けたストップリング（割 りリング）１０，１０との間で摺動自在、且つ、回動自在にスリーブ１１，１２ が装着されている。各スリーブ１１，１２は、施錠筒体６に設けられた施錠ボー ル９の遠心方向への移動を規制する規制部１１ａ，１２ａが内周面に突設され、 ストップリング１０側の内径側端部には、施錠ボール９の規制を解除するための 逃げ部１１ｂ，１２ｂが形成され、さらに、各スリーブ１１，１２内周面に突設 された規制部１１ａ，１２ａの係止段部７側の端面と、係止段部７の胴部７ｂ端 面との間にバネ１３，１４がそれぞれ介在され、施錠ボール９を規制する位置（ ストップリング１０，１０側）に付勢されている。Then, on both outer peripheral surfaces of both ends of the locking tubular body 6, a protrusion 7 a of a locking step portion 7 formed in a central circumferential portion of the locking tubular body 6 and a stop attached to both ends of the locking tubular body 6. Sleeves 11 and 12 are mounted so as to be slidable and rotatable between the rings (split rings) 10 and 10. Each of the sleeves 11 and 12 has restriction portions 11a and 12a, which restrict the movement of the locking ball 9 provided in the locking cylinder 6 in the centrifugal direction, projecting from the inner peripheral surface thereof, and the stop ring 10 side inner diameter side end. Escape portions 11b and 12b for releasing the regulation of the locking ball 9 are formed in the portion, and further, the locking step portion 7 side of the regulation portions 11a and 12a provided on the inner peripheral surfaces of the sleeves 11 and 12 is formed. The springs 13 and 14 are respectively interposed between the end surface of the locking step portion 7 and the end surface of the body portion 7b of the locking step portion 7 and are biased to the position (stop ring 10, 10 side) for restricting the locking ball 9.
【００１９】 次に、上記実施例の作用を説明する。 図１等に示すように、雄パイプ１の外径を縮径した縮径段部１ａと、雌パイプ ２の内径を拡径した拡径段部２ａとを嵌合し、施錠筒体６の両端円周部分に設け た施錠ボール９,９,・・を各パイプ１，２の施錠溝４，５に係合して、一対のパイ プ１，２が接続されている。この時、施錠筒体６に装着された各スリーブ１１， １２は、バネ１３，１４で施錠ボール９,９,・・を規制する位置（ストップリング １０側）に付勢されているので、各スリーブ１１，１２の内周面に突設された規 制部１１ａ，１２ａが、施錠ボール９の遠心方向への移動を規制し、施錠筒体６ と一対のパイプ１，２とをロックしている。さらに、雄パイプ１の縮径された縮 径段部１ａの外周面には、テフロン樹脂性等の耐腐食性に優れたＯリング３が取 り付けられているので、一対のパイプ１，２の嵌合部分の密封性を高め、腐食に よる流体洩れを防ぐ。Next, the operation of the above embodiment will be described. As shown in FIG. 1 and the like, a reduced diameter stepped portion 1a having a reduced outer diameter of the male pipe 1 and an enlarged diameter stepped portion 2a having an increased inner diameter of the female pipe 2 are fitted to each other, and A pair of pipes 1 and 2 are connected to each other by engaging locking balls 9, 9 ... At the circumferential portions of both ends with locking grooves 4 and 5 of the pipes 1 and 2, respectively. At this time, the sleeves 11 and 12 mounted on the locking cylinder 6 are urged by the springs 13 and 14 to positions (stop ring 10 side) that regulate the locking balls 9, 9 ,. Control parts 11a and 12a provided on the inner peripheral surfaces of the sleeves 11 and 12 restrict the movement of the locking ball 9 in the centrifugal direction, and lock the locking cylinder 6 and the pair of pipes 1 and 2. There is. Further, since the O-ring 3 having excellent corrosion resistance such as Teflon resin is attached to the outer peripheral surface of the reduced diameter stepped portion 1a of the male pipe 1, the pair of pipes 1, 2 Improves the sealing performance of the mating part of and prevents fluid leakage due to corrosion.
【００２０】 また、図２に示すように、施錠ボール９,９,・・と施錠溝４，５との係合を解除 する場合には、まず、バネ１３，１４の弾発力に抗して各スリーブ１１，１２を 施錠筒体６の係止段部７側に移動させて、各スリーブ１１，１２の一端部分に形 成した逃げ部１１ｂ，１２ｂを施錠ボール９,９,・・上に位置させる。この時、各 スリーブ１１，１２の他端部が係止段部７の突部７ａに当接するので、スリーブ １１，１２が必要以上に移動することはなく、上記位置決めが容易である。Further, as shown in FIG. 2, when the engagement between the locking balls 9, 9, ... And the locking grooves 4, 5 is released, first, the elastic force of the springs 13, 14 is resisted. By moving the sleeves 11 and 12 to the locking step 7 side of the locking cylinder body 6 so that the relief portions 11b and 12b formed at one end of the sleeves 11 and 12 are locked on the locking balls 9, 9 ,. Located in. At this time, the other ends of the sleeves 11 and 12 come into contact with the protrusion 7a of the locking step 7, so that the sleeves 11 and 12 do not move more than necessary and the positioning is easy.
【００２１】 次いで、各スリーブ１１，１２をこの位置に保持した状態で、施錠筒体６を一 方の雄パイプ１に移動させて施錠ボール９,９,・・と施錠溝４，５との係合を解除 させる。このように、施錠筒体６を一方の雄パイプ１側に移動させると、施錠ボ ール９,９,・・は、パイプ１，２の施錠溝４，５に沿って遠周方向に押されて施錠 溝４，５から飛び出し、スリーブ１１，１２の逃げ部１１ｂ，１２ｂとパイプ１ ，２外周面との間隙に入り込み、施錠溝４，５から完全に抜け出す。また、施錠 ボール９,９,・・がスリーブ１１，１２の逃げ部１１ｂ，１２ｂとパイプ１，２外 周面との間隙に入り込むと、施錠ボール９,９,・・の上部がスリーブ１１，１２の 逃げ部１１ｂ，１２ｂに当接し、バネの弾発力に抗してスリーブ１１，１２を規 制するので各スリーブ１１，１２を保持し続ける必要が無くなる。そして、移動 自在になった施錠筒体６を一方の雄パイプ１に退避させ、他方の雌パイプ２を離 脱させる。 このように、一対のパイプ１，２を分離する場合には、パイプの内圧を零にし てから行うものとする。なお、一対のパイプ１，２を分離する際、施錠筒体６を 退避させるパイプは、雄パイプ１，雌パイプ２のどちらでも良い。また、退避後 、退避した雄パイプ１の施錠溝４に施錠部材９,９,・・を係合させることにより、 施錠筒体６を雄パイプ１に留まらせることができる。なお、この場合、施錠筒体 ６を一方のパイプに仮に固定できるように施錠溝を２本形成するのが好ましい。Next, with the sleeves 11 and 12 held in this position, the locking cylinder 6 is moved to one of the male pipes 1 to move the locking balls 9, 9, ... And the locking grooves 4, 5. Disengage. Thus, when the locking cylinder 6 is moved to the one male pipe 1 side, the locking balls 9, 9, ... Are pushed in the circumferential direction along the locking grooves 4, 5 of the pipes 1, 2. Then, it pops out from the locking grooves 4 and 5, enters into the gap between the escape portions 11b and 12b of the sleeves 11 and 12 and the outer peripheral surfaces of the pipes 1 and 2, and completely escapes from the locking grooves 4 and 5. If the locking balls 9, 9, ... Enter into the gap between the escape portions 11b, 12b of the sleeves 11, 12 and the outer peripheral surfaces of the pipes 1, 2, the upper parts of the locking balls 9, 9 ,. Since the sleeves 11 and 12 are in contact with the escape portions 11b and 12b of 12 to control the elastic force of the springs, it is not necessary to keep holding the sleeves 11 and 12. Then, the movable locking cylinder 6 is retracted to the one male pipe 1 and the other female pipe 2 is released. In this way, when the pair of pipes 1 and 2 are separated, the internal pressure of the pipes should be set to zero. When separating the pair of pipes 1 and 2, either the male pipe 1 or the female pipe 2 may be used as the pipe for retracting the locking cylinder 6. Further, after retreating, by engaging the locking members 9, 9, ... With the retreating locking groove 4 of the male pipe 1, the locking cylinder body 6 can be retained in the male pipe 1. In this case, it is preferable to form two locking grooves so that the locking cylinder 6 can be temporarily fixed to one pipe.
【００２２】 再び一対のパイプ１，２を接続する場合は、一対のパイプ１，２を嵌合させ、 施錠筒体６を他方の雌パイプ２に向かって移動させて、施錠筒体６に設けられた 施錠ボール９,９,・・を各パイプ１，２の施錠溝４，５に係合させる。この時、各 スリーブ１１，１２を規制していた施錠ボール９,９,・・は、内径方向に移動して スリーブ１１，１２の規制を解除するので、バネ１３，１４によって付勢されて いたスリーブ１１，１２は、施錠ボール９,９,・・を規制する位置に弾発復帰し、 図１に示すように、スリーブ１１，１２の各規制部１１ａ，１２ａが施錠ボール ９,９,・・の遠心方向への移動を規制して、施錠筒体６と一対のパイプ１，２とを ロックする。When the pair of pipes 1 and 2 are to be connected again, the pair of pipes 1 and 2 are fitted to each other, and the locking cylinder 6 is moved toward the other female pipe 2 to be provided on the locking cylinder 6. .. are engaged with the locking grooves 4, 5 of the pipes 1, 2. At this time, the locking balls 9, 9, ... Which regulated the sleeves 11, 12 move in the inner diameter direction and release the regulation of the sleeves 11, 12, so that they are urged by the springs 13, 14. The sleeves 11 and 12 elastically return to the positions for regulating the locking balls 9, 9, ..., As shown in FIG. 1, the restricting portions 11a and 12a of the sleeves 11 and 12 lock the locking balls 9, 9 ,. Restricting the movement of in the centrifugal direction, locks the locking cylinder 6 and the pair of pipes 1 and 2.
