器のガス圧低下表示構造。[Claims for Utility Model Registration] 1. A bellows 2 is attached to a switch case 1 having a sealed structure so that it can expand and contract with changes in gas pressure within the case 1, and a bellows 2 is attached to the outside of the switch case 1. The actuating rod 2a of the bellows 2 is exposed inside the attached mechanism case 3, and can protrude to the outside from the protruding through hole 3a of the case 3 in conjunction with the movement of the actuating rod 2a. Display bar 16
In the gas pressure drop display structure in which the protrusion of the display rod 16 is made visible to confirm the drop in gas pressure inside the switch case 1, the protrusion through hole 3a of the mechanism case 3 is made of elastic material such as rubber. It is closed with a closing member 22 made of material, and the closing member 22 has a plurality of notches 2 so that the tip of the display rod 16 can protrude to the outside through the projection hole 3a and the closing member 22.
3. A gas pressure drop display structure for a gas switch, characterized in that the gas switch has a gas pressure drop display structure. 2. The gas pressure drop display structure for a gas switch according to claim 1, wherein the notches 23 of the closing member 22 are formed radially from the protruding center of the display rod 16. 3. Utility model registration claim No. 3, in which a display tube 21 is attached to the outside of the locking device case 3 to enclose the tip of the display rod 16 so that it can be seen from the outside when it protrudes to the outside through the closing member 22. The gas pressure drop display structure of the gas switch according to item 1 or 2.
