Claims

[Claims for Utility Model Registration] 1. In a locking device that uses a locking member to restrict opening/closing operations when gas pressure drops, the locking member 15 is configured to be able to maintain the unlocked position when the locking member 15 is moved from the locked position to the unlocked position. A locking device for opening/closing operation of a gas switch when gas pressure decreases, characterized by comprising a movement restricting means that is engaged with a locking member 15. 2. The movement restricting means includes an engaging protrusion 19.20 formed on the bar-shaped locking member 15, and an engaging stage with which the engaging protrusion 19.20 is engaged when the lock rod 15 is rotated from the unlocked position. A locking device for opening/closing operation when gas pressure decreases in a gas switch according to claim 1, which comprises a locking member 14 having portions 21 and 22. 3. The locking member 14 is a guide cylinder into which the lock rod 15 is fitted so that it can be moved between the locked position and the unlocked position, and is equipped with a spring 16 that biases the lock rod 15 toward the locked position. There, the retaining step portion 21,
22 is an engagement protrusion 19.2 of the lock rod 15 as it moves.
Gas pressure in the gas switch according to claim 2 of the utility model registration claim, which is formed by cutting out a part of the elongated hole 17 formed in the guide tube 14 so that the guide tube 14 is movably inserted. Lock device for opening/closing operation when lowered.
