Claims (1)

[Scope of Claim for Utility Model Registration] (1) A socket consisting of a socket and a plug, which opens a valve provided on the plug side when the socket is inserted into the plug, and also causes a disconnection tool provided on the socket side to protrude. is connected to a plug, and in this connected state, the disconnection tool protruding from the socket side so as to cover the plug is pushed back toward the socket side, thereby releasing the connection and closing the valve. , a ball insertion hole is passed through the cylindrical wall of the cylindrical socket body in a direction substantially perpendicular to the connection direction to the plug, and a cylindrical connection release tool is slidably inserted to the outside of the ball insertion hole portion; A ball is inserted into the ball insertion hole so as to be able to move in and out, and a circumferential groove into which the ball engages is formed in the mouthpiece of the plug. In a gas connection device, a connection release tool is provided, which is formed with a ball holding part that projects inward of the ball insertion hole and engages the ball in the circumferential groove, and a ball relief part that introduces the ball escaped from the circumferential groove. A gas connection device in which a relief slope is formed between the ball holding part and the ball relief part to cause the ball to escape toward the ball relief part when an external force of more than a certain level is applied to the socket. (2) A gas connection device consisting of a socket and a plug, which opens a valve provided on the plug side when the socket is inserted into the plug, and has a cylindrical wall of the cylindrical socket body that indicates the connection direction to the plug. A ball insertion hole is penetrated in a substantially orthogonal direction, a ball is inserted into the ball insertion hole so as to be movable in an inward/outward direction, and a circumferential groove is formed in the mouth portion of the plug for the ball to fit into.
A gas connection device that uses a spring plate to force a ball into a circumferential groove so that it can freely escape. (3) A gas connection device consisting of a socket and a plug, which opens a valve provided on the plug side when the socket is inserted into the plug, and has a cylindrical wall of the cylindrical socket body that indicates the connection direction to the plug. The insertion hole is penetrated in a substantially orthogonal direction, the connector is inserted into the insertion hole so as to be movable in the inward and outward directions, a circumferential groove is formed in which the connector engages in the mouthpiece of the plug, and the connector is inserted into the spring plate. A gas connector that is formed in a series at the tip and is biased by a spring plate into a circumferential groove so that the connector can be released freely.
