上部開口外周に連結用のフェルールフランジを有するガラス製の反応容器と、下部開口外周に連結用のフェルールフランジを有するガラス製の蓋体とを接合する場合、従来は、サニタリー配管を接続する際に用いられるサニタリー継手用のクランプを基にした構造を採用することが多かった。このクランプとして、半円状に２分割された２つの半割体の基端部をヒンジで開閉自在に連結し、両半割体の先端部に連結部材を設けるとともに、２つの半割体の内周部に、連結するフェルールフランジの当接部分の外周を覆う凹溝を備えたものがあり、半割体の凹溝でフェルールフランジの当接部分を覆い、連結部材により半割体の先端部同士を連結すると共に凹溝によって双方のフェルールフランジを、接合する配管の軸方向に締め付けることにより、気密性や水密性を確保しながら双方のフェルールフランジを接合するものがあった（例えば、特許文献１参照。）。   When joining a glass reaction container having a ferrule flange for connection at the upper opening outer periphery and a glass lid having a ferrule flange for connection at the lower opening outer periphery, conventionally, when connecting a sanitary pipe, In many cases, the structure based on the clamp for the sanitary joint used is adopted. As this clamp, the proximal end portions of two half bodies divided into two semicircular shapes are hingedly connected by a hinge, and a connecting member is provided at the tip end portions of both half bodies, and the two half bodies are The inner peripheral portion may be provided with a recessed groove covering the outer periphery of the contact portion of the ferrule flange to be connected, the contact groove of the ferrule flange is covered by the recessed groove of the half body, and the tip of the half body is connected by the connection member. There has been a case where both ferrule flanges are joined while securing airtightness and water tightness by connecting the parts together and fastening both ferrule flanges in the axial direction of the joined pipe by the concave groove (for example, patent) Reference 1.).

A pair of spring members 23, 23 are provided. Further, the hooking portion 20e has a hook-shaped hooking piece 20k engaged with the engaging portion 21 at the tip.

上述のように形成された反応容器用クランプ１１で反応容器１２と蓋体１３とを接合する際には、蓋体側フェルールフランジ１３ａの装着溝１３ｂにＯリング１４を装着し、容器側フェルールフランジ１２ａと蓋体側フェルールフランジ１３ａの端面同士を互いに付き合わせ、容器側フェルールフランジ１２ａと蓋体側フェルールフランジ１３ａとの外周に、フランジ挟着片１９の上部押圧片１９ａを蓋体側フェルールフランジ１３ａの上面に、下部押圧片１９ｂを容器側フェルールフランジ１２ａの下面にそれぞれ当接させるようにして、反応容器用クランプ１１の第１半割体１５と第２半割体１６とを配置する。   When joining the reaction container 12 and the lid 13 with the reaction container clamp 11 formed as described above, the O-ring 14 is attached to the mounting groove 13b of the lid side ferrule flange 13a, and the container side ferrule flange 12a The end faces of the lid side ferrule flange 13a are butted together, and the upper pressing piece 19a of the flange holding piece 19 is placed on the top surface of the lid side ferrule flange 13a on the outer periphery of the container side ferrule flange 12a and the lid side ferrule flange 13a. The first half 15 and the second half 16 of the reaction vessel clamp 11 are disposed such that the lower pressing piece 19b is in contact with the lower face of the vessel-side ferrule flange 12a.

この状態で、連結部材１８のレバー部２０ｃと掛止め部２０ｅとを係合部２１方向に延出させた状態で、掛止め部２０ｅの掛止め片２０ｋを係合部２１に掛け止めし、レバー部２０ｃを取付部２０ａ側に回動し、通常のパッチン錠と同様に、デッドポイントを越えて取付部２０ａの上部に沿った状態とすることにより、掛止め部２０ｅが係合部２１を取付部２０ａ側に引き寄せながら、取付部２０ａの上部に配置されたレバー部２０ｃの両側に沿った状態になってロックされる。   In this state, with the lever portion 20c of the connecting member 18 and the hooking portion 20e extended in the direction of the engaging portion 21, the hooking piece 20k of the hooking portion 20e is hooked to the engaging portion 21, The hook portion 20e is engaged with the engaging portion 21 by rotating the lever portion 20c to the mounting portion 20a side and setting it along the upper portion of the mounting portion 20a beyond the dead point in the same manner as a normal patchon lock. While being pulled toward the mounting portion 20 a side, the lever portion 20 c disposed at the top of the mounting portion 20 a is locked along both sides of the lever portion 20 c.

これにより、第１半割体１５と第２半割体１６とがリング状に連結され、付き合わされた容器側フェルールフランジ１２ａと蓋体側フェルールフランジ１３ａとの外周部を、薄板によって帯状に形成した両半割体１５，１６の弾性変形及びフランジ挟着片１９の弾性変形の作用で内周側に押圧し、反応容器１２の中心軸と蓋体１３との中心軸とを一致させることができる。また、フランジ挟着片１９の上部押圧片１９ａが蓋体側フェルールフランジを下方に押圧し、下部押圧片１９ｂが容器側フェルールフランジ１２ａを上方に押圧することにより、双方のフェルールフランジ１２ａ，１３ａの端面同士が互いに近付くように押し付けられ、シール性を保持しながら反応容器１２を蓋体１３とを確実に連結することができる。   As a result, the first half body 15 and the second half body 16 are connected in a ring shape, and the outer peripheral portions of the container side ferrule flange 12a and the lid side ferrule flange 13a which are attached to each other are formed in a strip shape with thin plates. The center axis of the reaction vessel 12 and the center axis of the lid 13 can be made to coincide with each other by pressing to the inner peripheral side by the action of the elastic deformation of both halves 15 and 16 and the elastic deformation of the flange clamping piece 19 . Further, the upper pressing piece 19a of the flange clamping piece 19 presses the lid side ferrule flange downward, and the lower pressing piece 19b presses the container side ferrule flange 12a upward, so that the end faces of both ferrule flanges 12a and 13a The reaction vessels 12 can be reliably connected to the lid 13 while being pressed so as to approach each other, maintaining the sealing performance.

さらに、レバー部２０ｃの回動端側に掛止め部２０ｅの第２支軸２０ｄを配置したので、図５に示すように、掛止め片２０ｋを係合部２１に係合させる際の第１支軸２０ｂと掛止め片２０ｋとの距離を十分に長くすることができ、反応容器１２と蓋体１３とを接合する際に、フランジ挟着片１９の先端がフェルールフランジ１２ａ，１３ａの外周部に当接して先端部１５ｂ，１６ｂ同士が離れた状態になっていても、掛止め片２０ｋを係合部２１に容易に係合させることができ、レバー部２０ｃの回動操作によって両半割体１５，１６を締め付けてフランジ挟着片１９の弾性でフェルールフランジ１２ａ，１３ａを確実に挟着することができる。   Furthermore, since the second support shaft 20d of the hooking portion 20e is disposed on the rotating end side of the lever portion 20c, as shown in FIG. The distance between the support shaft 20b and the hooking piece 20k can be made sufficiently long, and when the reaction container 12 and the lid 13 are joined, the tip of the flange clamping piece 19 is the outer peripheral portion of the ferrule flanges 12a and 13a. Even when the tip end portions 15b and 16b are in contact with each other and the tip end portions 15b and 16b are separated from each other, the retaining piece 20k can be easily engaged with the engaging portion 21. The ferrule flanges 12a and 13a can be reliably clamped by the elasticity of the flange clamping pieces 19 by clamping the bodies 15 and 16.

上述の反応容器用クランプ１１によれば、反応容器１２と蓋体１３との中心軸を一致させた状態で接合することができることから、蓋体１３に設ける温度計、ｐＨセンサ、攪拌シャフトなどを所定の位置に保持することができ、良好な実験を繰り返して行うことができる。また、フランジ挟着片１９の上部押圧片１９ａと下部押圧片１９ｂとは、両フェルールフランジ１２ａ，１３ａの内周側の厚肉に形成されている部分を押圧することから、双方のフェルールフランジ１２ａ，１３ａの端面同士を互いに近付く方向に、効果的に押し付けることができ、シール性の向上を図ることができる。   According to the above-mentioned clamp 11 for reaction container, since it can join in the state which made the central axis of reaction container 12 and lid 13 correspond, a thermometer, pH sensor, a stirring shaft, etc. provided in lid 13 It can be held in place and good experiments can be repeated. Further, since the upper pressing piece 19a and the lower pressing piece 19b of the flange sandwiching piece 19 press a thick portion formed on the inner peripheral side of both ferrule flanges 12a, 13a, both ferrule flanges 12a , 13a can be effectively pressed in the direction in which the end faces of each other approach each other, and the sealing performance can be improved.

また、連結部材１８の掛止め部２０ｅは、スプリング部材２３，２３を介してレバー部２０ｃの長さ方向にスライド可能に連結されていることから、各フェルールフランジ１２ａ，１３ａの直径に製造誤差があったとしても微調整が可能となり、工具などを用いて調整作業を行う必要がない。また、連結部材１８は、取付部２０ａの上部に配置されたレバー部２０ｃの外側に、係合部２１を係合した掛止め部２０ｅが重ねて配置されてロックされることから、ロックされた状態で、連結部材１８が第１半割体１５と第２半割体１６の外側に大きく突出することがなく、反応容器用クランプ１１の小型化を図ることができる。   Further, since the hooking portion 20e of the connecting member 18 is slidably coupled in the longitudinal direction of the lever portion 20c via the spring members 23, 23, manufacturing errors occur in the diameters of the respective ferrule flanges 12a, 13a. Even if there is, fine adjustment is possible, and it is not necessary to perform adjustment using a tool or the like. Further, the connecting member 18 is locked because the hooking portion 20e engaging with the engaging portion 21 is overlapped and arranged on the outside of the lever portion 20c disposed on the upper portion of the mounting portion 20a. In the state, the connecting member 18 does not largely protrude to the outside of the first half 15 and the second half 16, and the reaction container clamp 11 can be miniaturized.

さらに、反応容器用クランプ１１は、連結部材１８を外して大きく開くことができることから、蓋体１３に設けられた温度計、ｐＨセンサ、攪拌シャフトなどに邪魔されることなく簡単に着脱することができる。また、金属の薄板で製作できるので、反応容器用クランプの軽量化を図ることができ、製造コストの削減も図れる。   Furthermore, since the reaction container clamp 11 can be widely opened by removing the connection member 18, it can be easily attached and detached without being disturbed by a thermometer, a pH sensor, a stirring shaft or the like provided on the lid 13. it can. In addition, since it can be made of a thin metal plate, it is possible to reduce the weight of the reaction container clamp and to reduce the manufacturing cost.

なお、本発明の反応容器用クランプは、上述の形態例に限るものではなく、連結部の構造は任意である。また、フランジ挟着片は、付き合わせた状態のフェルールフランジを接合方向に押圧できればよく、形状や設置数は任意に設定できる。さらに、各半割体へのヒンジ部、連結部材、フランジ挟着片の取り付けは、ビス止め、溶接、リベットなどの各種固着手段を使用することができる。   In addition, the clamp for reaction containers of this invention is not restricted to the above-mentioned embodiment, The structure of a connection part is arbitrary. Further, the flange clamping pieces only have to be able to press the ferrule flanges in the butted state in the joining direction, and the shape and the number of installation can be set arbitrarily. Furthermore, attachment of a hinge part, a connection member, and a flange clamping piece to each half body can use various fixing means, such as screwing, welding, and a rivet.
