Description

この発明は、流体を輸送する配管相互、ホース相互等を接続するレバー式カップリングに関する。   The present invention relates to a lever type coupling for connecting pipes for transporting fluids, hoses and the like.

従来のレバー式カップリングは、一方の配管やホースと接続される筒状のアダプターと、このアダプターが内挿され、他方の配管やホースと接続される筒状のカプラーとから構成されている。前記アダプターにはその外周面に凹部が設けられ、前記カプラーには凹部に係合してアダプターとカプラ-とを結合状態でロックするカム部を有する２本の締結カムレバーを備えている（例えば、特許文献１参照。）。   The conventional lever type coupling is composed of a cylindrical adapter connected to one pipe or hose, and a cylindrical coupler in which this adapter is inserted and connected to the other pipe or hose. The adapter has a recess on its outer peripheral surface, and the coupler includes two fastening cam levers having a cam portion that engages the recess and locks the adapter and the coupler in a coupled state (for example, (See Patent Document 1).

このレバー式カップリングは、図６に示すように、筒状のアダプター１が内挿される筒状のカプラー２に外方に突出する一対の突出部３が対称的に設けられ、これら突出部３には枢支軸４を中心に回動可能に枢着された締結カムレバー５が設けられている。   In this lever type coupling, as shown in FIG. 6, a pair of projecting portions 3 projecting outward are symmetrically provided on a tubular coupler 2 into which a tubular adapter 1 is inserted. Is provided with a fastening cam lever 5 pivotally mounted about a pivot shaft 4.

締結カムレバー５の基端部にはカム部６が設けられ、このカム部６は締結カムレバー５の回動によってカプラー２の側壁に設けられた開口７からカプラー２の内部に突没可能になっている。アダプター１の外周壁にはカム部６と係合する凹部８が設けられ、アダプター１をカプラー２に内挿した状態で、締結カムレバー５を枢支軸４を中心として回動すると、カム部６が凹部８の面上を回動しながら凹部８に係合してアダプター１とカプラー２が結合状態でロックされるようになっている。
すなわち、締結カムレバー５がカプラー２のアダプター１との接続側に回動した状態においてはカム部６が開口７から没入してアンロック状態となり、締結カムレバー５が逆方向に回動した状態においてはカム部６が開口７から内部に突出してアダプター１の凹部８と係合してロック状態となる。
特開２００１−７４１８６号公報 A cam portion 6 is provided at the base end portion of the fastening cam lever 5, and the cam portion 6 can be projected and retracted into the coupler 2 from the opening 7 provided on the side wall of the coupler 2 by the rotation of the fastening cam lever 5. Yes. A concave portion 8 that engages with the cam portion 6 is provided on the outer peripheral wall of the adapter 1. When the fastening cam lever 5 is rotated about the pivot shaft 4 in a state where the adapter 1 is inserted in the coupler 2, the cam portion 6 is provided. The adapter 1 and the coupler 2 are locked in a coupled state by engaging with the recess 8 while rotating on the surface of the recess 8.
That is, when the fastening cam lever 5 is rotated to the connection side of the coupler 2 with the adapter 1, the cam portion 6 is recessed from the opening 7 to be unlocked, and when the fastening cam lever 5 is rotated in the reverse direction. The cam portion 6 protrudes inward from the opening 7 and engages with the concave portion 8 of the adapter 1 to be locked.
JP 2001-74186 A

しかしながら、前述のように構成されたレバー式カップリングは、カプラー２のアダプター１との接続側が上向きに位置しているとき、締結カムレバー５をカプラー２のアダプター１との接続側（上方）に回動してアンロック状態にしようとしても、締結カムレバー５が自重によって下方へ回動してカム部６が開口７から内部に突出してしまう。従って、アダプター１をカプラー２に内挿しようとしても、カプラー２の先端がカム部６に当接してしまい、締結カムレバー５を手指で押えてカプラー２のアダプター１との接続側（上方）に回動しないと接続できず、操作性が悪い。
また、締結カムレバー５を逆方向（下方）に回動してカム部６が開口７から突出してアダプター１の凹部８と係合してロック状態にあっても、振動や衝撃が加わったときに、締結カムレバー５がアンロック側に回動してアダプター１とカプラー２との結合が解除される虞がある。
この発明は、前記事情に着目してなされたもので、この目的とするところは、締結カムレバーが不用意に回動してロック状態が解除される虞はなく、また締結カムレバーを所定位置に保持してカプラーに対するアダプターの結合時の操作もし易いレバー式カップリングを提供することにある。 However, the lever-type coupling configured as described above rotates the fastening cam lever 5 to the connection side (upward) of the coupler 2 with the adapter 1 when the connection side of the coupler 2 with the adapter 1 is positioned upward. Even if it tries to move to the unlocked state, the fastening cam lever 5 rotates downward due to its own weight, and the cam portion 6 protrudes from the opening 7 to the inside. Therefore, even if the adapter 1 is inserted into the coupler 2, the tip of the coupler 2 comes into contact with the cam portion 6, and the fastening cam lever 5 is pushed with a finger and turned to the connection side (upward) of the coupler 2 with the adapter 1. If it does not move, it cannot be connected and operability is poor.
Further, even when the fastening cam lever 5 is rotated in the reverse direction (downward) so that the cam portion 6 protrudes from the opening 7 and engages with the concave portion 8 of the adapter 1 to be in a locked state, vibration or impact is applied. The fastening cam lever 5 may turn to the unlock side and the coupling between the adapter 1 and the coupler 2 may be released.
The present invention has been made paying attention to the above circumstances. The purpose of the present invention is to prevent the fastening cam lever from inadvertently rotating and releasing the locked state, and to hold the fastening cam lever in a predetermined position. Another object of the present invention is to provide a lever type coupling that is easy to operate when the adapter is coupled to the coupler.

There is an effect that the adapter can be easily coupled to the coupler while being held in position.

以下、この発明の実施の形態を図面に基づいて説明するが、従来と同一構成部分は同一番号を付して説明を省略する。   DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the drawings.

図１〜図５は第１の実施形態を示し、図１〜図３に示すように、カプラー２の外壁に対称的に設けられ、外方に突出する突出部３は間隙部１１を挟んで対向する一対の突起部１２ａ，１２ｂが設けられている。一対の突起部１２ａ，１２ｂには締結カムレバー５を枢支する枢支軸４の両端部が軸支され、間隙部１１に締結カムレバー５が回動可能に枢着されている。   1 to 5 show the first embodiment, and as shown in FIGS. 1 to 3, the protrusions 3 that protrude symmetrically are provided on the outer wall of the coupler 2 with the gap 11 interposed therebetween. A pair of opposing protrusions 12a and 12b are provided. Both ends of a pivot shaft 4 that pivotally supports the fastening cam lever 5 are pivotally supported by the pair of protrusions 12a and 12b, and the fastening cam lever 5 is pivotally attached to the gap portion 11.

締結カムレバー５の基端部にはカム部６が設けられ、このカム部６は締結カムレバー５の回動によってカプラー２の側壁に間隙部１１と貫通して設けられた開口７からカプラー２の内部に突没可能になっている。すなわち、締結カムレバー５がカプラー２のアダプター１との接続側（上方）に回動した状態においてはカム部６が開口７から没入してアンロック状態となり、締結カムレバー５が逆方向（下方）に回動した状態においてはカム部６が開口７から内部に突出してアダプター１の凹部８と係合してロック状態となる。   A cam portion 6 is provided at the base end portion of the fastening cam lever 5, and this cam portion 6 is connected to the inside of the coupler 2 through an opening 7 provided through the gap 11 on the side wall of the coupler 2 by the rotation of the fastening cam lever 5. It is possible to sneak into. That is, when the fastening cam lever 5 is rotated to the connection side (upward) of the coupler 2 with the adapter 1, the cam portion 6 is immersed from the opening 7 to be unlocked, and the fastening cam lever 5 is moved in the reverse direction (downward). In the rotated state, the cam portion 6 protrudes inward from the opening 7 and engages with the concave portion 8 of the adapter 1 to be locked.

図４に示すように、締結カムレバー５の基端部における枢支軸４よりカム面６ａ側の側面には底の浅い第１の係合凹部１３が設けられ、枢支軸４より反カム面６ｂ側の側面には底の深い第２の係合凹部１４が設けられている。そして、第１の係合凹部１３と第２の係合凹部１４は枢支軸４を中心とする同一回転軌跡上に位置している。
さらに、図５に示すように、一方の突起部１２ａには枢支軸４と平行し、かつ第１の係合凹部１３と第２の係合凹部１４の回転軌跡上に対向してピン穴１５が設けられている。このピン穴１５は内側が小径部１６ａ、外側が大径部１６ｂに形成され、さらに大径部１６ｂの開口端の内周面には雌ねじ部１６ｃが設けられている。ピン穴１５には突起部１２ａの外側からロックピン１７が進退自在に挿入されている。 As shown in FIG. 4, a first engagement recess 13 having a shallow bottom is provided on a side surface of the base end portion of the fastening cam lever 5 closer to the cam surface 6 a than the pivot shaft 4. A second engaging recess 14 having a deep bottom is provided on the side surface on the 6b side. The first engagement recess 13 and the second engagement recess 14 are located on the same rotation locus with the pivot shaft 4 as the center.
Further, as shown in FIG. 5, the one projection 12 a has a pin hole parallel to the pivot shaft 4 and facing the rotation locus of the first engagement recess 13 and the second engagement recess 14. 15 is provided. The pin hole 15 is formed with a small-diameter portion 16a on the inside and a large-diameter portion 16b on the outside, and a female screw portion 16c is provided on the inner peripheral surface of the open end of the large-diameter portion 16b. A lock pin 17 is inserted into the pin hole 15 from the outside of the protrusion 12a so as to be able to advance and retract.

ロックピン１７は、第１の係合凹部１３と第２の係合凹部１４に係合しやすいように先端部が丸みを帯びており、基端部の貫通孔１８にはリング状の指押え部１９が取付けられている。このロックピン１７は中間部が雌ねじ部１６ｃにねじ込み固定された駒２０によって支持されている。ロックピン１７の先端側にはバネストッパ２１が固定され、このバネストッパ２１と駒２０との間にはコイルバネ２２がロックピン１７に嵌合して圧縮した状態に設けられている。従って、ロックピン１７はコイルバネ２２のバネ力によって前進方向、つまり先端部が締結カムレバー５の側面に当接する方向に付勢されている。   The lock pin 17 has a rounded tip so that it can be easily engaged with the first engagement recess 13 and the second engagement recess 14, and a ring-shaped finger presser is formed in the through hole 18 at the base end. Part 19 is attached. The lock pin 17 is supported by a piece 20 having an intermediate portion screwed and fixed to the female screw portion 16c. A spring stopper 21 is fixed to the distal end side of the lock pin 17, and a coil spring 22 is provided between the spring stopper 21 and the piece 20 in a state of being compressed by being fitted to the lock pin 17. Therefore, the lock pin 17 is urged by the spring force of the coil spring 22 in the forward direction, that is, in the direction in which the tip portion contacts the side surface of the fastening cam lever 5.

さらに、ロックピン１７に取付けられたリング状の指押え部１９は、そのリング中間部１９ａが突起部１２ａの角部２３に位置している。従って、指押え部１９を手指で押えて突起部１２ａ方向に押し込むと、指押え部１９は角部２３を支点とし、てこ作用によってロックピン１７を付勢力に抗して後退させることができるようになっている。   Further, the ring-shaped finger pressing portion 19 attached to the lock pin 17 has a ring intermediate portion 19a positioned at the corner portion 23 of the projection portion 12a. Therefore, when the finger presser 19 is pressed with a finger and pushed in the direction of the protrusion 12a, the finger presser 19 can be moved backward against the urging force by lever action with the corner 23 as a fulcrum. It has become.

次に、前記実施形態の作用について説明する。
カプラー２のアダプター１との接続側を上向きに位置しているとき、締結カムレバー５をカプラー２のアダプター１との接続側（上方）に回動してアンロック状態にすると、締結カムレバー５に設けられた第１の係合凹部１３がロックピン１７に対向する。従って、ロックピン１７はコイルバネ２２のバネ力によって前進し、ロックピン１７の先端部が第１の係合凹部１３に係合し、さらにコイルバネ２２のバネ力によって係合状態に保持される。
このため、締結カムレバー５が自重によって下方へ回動することはなく、締結カムレバー５はカプラー２の上方に回動してアンロック状態に保持され、カム部６は開口７から没入される。従って、アダプター１をカプラー２に内挿するとき、アダプター１の先端がカム部６に干渉することなくカプラー２に対してアダプター１を容易に接続できる。 Next, the operation of the embodiment will be described.
When the connecting side of the coupler 2 with the adapter 1 is positioned upward, the fastening cam lever 5 is provided on the fastening cam lever 5 by rotating the connecting cam lever 5 to the connecting side with the adapter 1 of the coupler 2 (upward). The formed first engaging recess 13 faces the lock pin 17. Therefore, the lock pin 17 moves forward by the spring force of the coil spring 22, the tip end portion of the lock pin 17 engages with the first engagement recess 13, and is held in the engaged state by the spring force of the coil spring 22.
For this reason, the fastening cam lever 5 does not turn downward due to its own weight, the fastening cam lever 5 turns upward above the coupler 2 and is held in the unlocked state, and the cam portion 6 is retracted from the opening 7. Therefore, when the adapter 1 is inserted into the coupler 2, the adapter 1 can be easily connected to the coupler 2 without the tip of the adapter 1 interfering with the cam portion 6.

この状態から締結カムレバー５を下方に回動すると、カム部６が開口７から突出してアダプター１の凹部８と係合してロック状態となり、このとき締結カムレバー５に設けられた第２の係合凹部１４がロックピン１７に対向する。従って、ロックピン１７はコイルバネ２２のバネ力によって前進し、ロックピン１７の先端部が第２の係合凹部１４に係合し、さらにコイルバネ２２のバネ力によって係合状態に保持される。
第２の係合凹部１４は底が深く、ロックピン１７と深く係合しているため、レバー式カップリングに振動や衝撃が加わってもロックピン１７と第２の係合凹部１４との係合が外れることはなく、締結カムレバー５がアンロック側に回動してアダプター１とカプラー２との結合が解除される虞はない。 When the fastening cam lever 5 is rotated downward from this state, the cam portion 6 protrudes from the opening 7 and engages with the concave portion 8 of the adapter 1 to be in a locked state. At this time, the second engagement provided on the fastening cam lever 5 The recess 14 faces the lock pin 17. Therefore, the lock pin 17 moves forward by the spring force of the coil spring 22, the tip end portion of the lock pin 17 engages with the second engagement recess 14, and is held in the engaged state by the spring force of the coil spring 22.
Since the second engagement recess 14 has a deep bottom and is deeply engaged with the lock pin 17, the engagement between the lock pin 17 and the second engagement recess 14 is not affected even if vibration or impact is applied to the lever type coupling. There is no possibility that the coupling cam lever 5 is turned to the unlock side and the coupling between the adapter 1 and the coupler 2 is released.

また、ロックピン１７と第２の係合凹部１４との係合を解除し、締結カムレバー５をアンロック側に回動してアダプター１とカプラー２との結合を解除する場合、指押え部１９の自由端側を手指で押えて突起部１２ａ方向に押し込むと、指押え部１９は角部２３を支点とし、てこ作用によってロックピン１７を付勢力に抗して後退させることができる。従って、ロックピン１７の先端部を第２の係合凹部１４から脱出させてロックピン１７と第２の係合凹部１４との係合を解除できる。このため、締結カムレバー５が回動自在となり、締結カムレバー５を上方に回動してアンロック状態にすることができる。   When the engagement between the lock pin 17 and the second engagement recess 14 is released and the fastening cam lever 5 is rotated to the unlock side to release the connection between the adapter 1 and the coupler 2, the finger presser 19 When the free end side is pressed with the fingers and pushed in the direction of the protruding portion 12a, the finger pressing portion 19 can use the corner portion 23 as a fulcrum and retract the lock pin 17 against the urging force by lever action. Accordingly, it is possible to disengage the lock pin 17 from the second engagement recess 14 by releasing the tip of the lock pin 17 from the second engagement recess 14. For this reason, the fastening cam lever 5 becomes rotatable, and the fastening cam lever 5 can be turned upward to be in an unlocked state.
