Abstract

当該意匠に係る物品は、「使用状態を表した参考図1」および「参考図2」の断面図および外観図にあるように、ボンベAの開口に装着される略円筒状のプラグ1であって、ボンベAに収容または排出される流動体をボンベ・ボンベ間またはボンベ・流体圧回路間で給排する通路をなすものである。給排通路2はプラグ1の中心軸線上に形成され、その先端2aは「使用状態を表した参考図3」にあるように、他のボンベまたは流体圧回路(図示せず)からの連絡通路端2bと対向され、半割れ構造重ね合わせタイプのクランプ3が4本のボルト3a(参考図2参照)の締結により固定される。「プラグの構造を説明するための参考図4」にあるように、プラグ1にはボンベの開口内壁との気密を保つO-リング5,6が設置され、その収容空間を埋めるバックアップリング7,8も介装される。さらにはプラグ1の奧端にはリテーナー9がねじ部9aを介して取り付けられ、O-リング6の脱落を阻止している。なお、凹み12は、ピンスパナを差し込みリテーナー9を回すため、背部周上2ヶ所に設けられた小さな空間である。このようなボンベ用のプラグは単体で市場に流通されるが、給排通路2の径、O-リング5,6の耐圧程度により商品はライナップ化される。プラグ1の飛び出しを阻止するスレッドリング10(参考図3を参照)は、その左端面でプラグ1の中央の円輪状面1aを押さえるものである。その外周ネジ(雄ねじ)10aがボンベ開口部のネジ(雌ねじ)11に螺着される結果、ボンベ側の部品として扱われ、プラグ1はスレッドリング10とは独立して取り引される。The article related to the design is a substantially cylindrical plug 1 attached to the opening of the cylinder A, as shown in the cross-sectional views and external views of "Reference FIG. 1 and Reference FIG. 2 showing the usage state". Therefore, the fluid contained or discharged in the cylinder A forms a passage for supplying and discharging the fluid between the cylinders or between the cylinders and the fluid pressure circuit. The supply / discharge passage 2 is formed on the central axis of the plug 1, and its tip 2a is a connecting passage from another cylinder or a fluid pressure circuit (not shown) as shown in "Reference FIG. 3 showing the usage state". Facing the end 2b, the half-split structure overlapping type clamp 3 is fixed by fastening four bolts 3a (see Reference FIG. 2). As shown in "Reference Figure 4 for Explaining the Structure of the Plug", the plug 1 is equipped with O-rings 5 and 6 that maintain airtightness with the inner wall of the opening of the cylinder, and the backup ring 7 that fills the accommodation space. 8 is also intervened. Further, a retainer 9 is attached to the back end of the plug 1 via a threaded portion 9a to prevent the O-ring 6 from falling off. The dents 12 are small spaces provided at two locations on the circumference of the back for inserting a pin spanner and turning the retainer 9. Such cylinder plugs are distributed on the market as a single unit, but the products are lined up depending on the diameter of the supply / discharge passage 2 and the pressure resistance of the O-rings 5 and 6. The thread ring 10 (see Reference FIG. 3) that prevents the plug 1 from popping out presses the circular ring-shaped surface 1a at the center of the plug 1 with its left end surface. As a result of the outer peripheral screw (male screw) 10a being screwed to the screw (female screw) 11 at the opening of the cylinder, it is treated as a part on the cylinder side, and the plug 1 is traded independently of the thread ring 10.
