A guide angle is installed on the outer periphery of the curved surface, a sealing ring is installed in the annular concave tank, and the effect of forming a preload space in the sealing ring by the curved surface is achieved. By installing the guide angle, the plug body and the external coupling device can be stopped together to achieve the effect of limiting the position, and the purpose of preventing the seal ring from being deformed due to excessive pressure is achieved.

一般プラグは図１、図２に示すとおり、プラグ本体１を含む。該プラグ本体１の一端は平面部１３を設置し、また該プラグ本体１の平面部１３は連結部１１が伸びて設置する。該連結部１１は外ネジ紋を設置し、また該連結部１１は、外部連結装置２と相互に連結する。該連結部１１とプラグ本体１の間には環凹槽１２を設置し、また該環凹槽１２は密封環１４を設置し、該密封環１４とプラグ本体１の平面部１３は相互に停止する。また該プラグ本体１は中空部１０を形成し、該連結部１１によって該プラグ本体１が外部連結装置２で相互に連接する目的を達成する。また該プラグ本体１の中空部１０は外部連結装置２の気体に流動効果を与える。 The general plug includes a plug body 1 as shown in FIGS. One end of the plug body 1 is provided with a flat part 13, and the flat part 13 of the plug body 1 is provided with a connecting part 11 extending. The connecting portion 11 is provided with an external screw pattern, and the connecting portion 11 is connected to the external connecting device 2. An annular concave tank 12 is installed between the connecting portion 11 and the plug body 1, and the annular concave tank 12 is provided with a sealing ring 14, and the sealing ring 14 and the flat portion 13 of the plug body 1 stop each other. To do. Further, the plug body 1 forms a hollow portion 10 and achieves the purpose of connecting the plug body 1 to each other by the external connection device 2 by the connection portion 11. Further, the hollow portion 10 of the plug body 1 gives a flow effect to the gas of the external connection device 2.

該「プラグ」は外部連結装置２に連接する目的を達成するものであるが、該プラグ本体１一端には平面部１３を設置し、該密封環１４と平面部１３は互いに停止する。そのため、ユーザーが該プラグ本体１の連結部１１と外部連結装置２を相互連結すると、該プラグ本体１の平面部１３は該密封環１４が外部連結装置２と相互に接合する。そのため、ユーザーがプラグ本体１と外部連結装置２の密接度を更に高めたい場合、再度該プラグ本体１を回転し、該プラグ本体１の平面部１３と外部連結装置２を密封環１４で相互に押して強く接合するが、該密封環１４は長時間加圧すると、変形するという欠点があり、密封環１４は予圧空間が足りないために破裂してしまう。更に該プラグ本体１の連結部１１の外ネジ紋と外部連結装置２の内ネジ紋は密接に螺合し、該外部連結装置２の内ネジ紋が直線歯ネジ紋、または傾斜歯ネジ紋、または異なる角度のネジ紋である時、相互に対応するプラグ本体１の連結部１１に交換することで、やっと外部連結装置と相互に連結できるようになり不便である。 The “plug” achieves the purpose of connecting to the external connecting device 2, but a flat portion 13 is installed at one end of the plug body 1, and the sealing ring 14 and the flat portion 13 stop each other. Therefore, when the user interconnects the connecting portion 11 of the plug main body 1 and the external connecting device 2, the sealing ring 14 of the flat portion 13 of the plug main body 1 is joined to the external connecting device 2. Therefore, when the user wants to further increase the closeness between the plug body 1 and the external connection device 2, the plug body 1 is rotated again, and the flat portion 13 of the plug body 1 and the external connection device 2 are mutually connected by the sealing ring 14. The seal ring 14 is pressed and strongly joined. However, when the seal ring 14 is pressurized for a long time, there is a defect that the seal ring 14 is deformed, and the seal ring 14 is ruptured due to insufficient preload space. Further, the external screw pattern of the connecting portion 11 of the plug body 1 and the internal screw pattern of the external connection device 2 are closely screwed together, and the internal screw pattern of the external connection device 2 is a straight tooth screw pattern or an inclined tooth screw pattern, Alternatively, when the screw pattern has a different angle, it is inconvenient because it can be finally connected to the external connecting device by replacing the connecting portions 11 of the plug body 1 corresponding to each other.
