<p>[PROBLEMS] To provide a seal breaking device of a gas cylinder suitably used, for example, for a carbon dioxide fire extinguisher using a cartridge type gas cylinder, incorporating a single or a plurality of gas cylinders, reduced in size and weight and improved in aesthetic appearance, capable of easily breaking these gas cylinders at a time, rapidly usable with safety, and capable of providing stable and sufficient fire extinguishing action by preventing dry ice from being frozen and a flow passage from being clogged after unsealing. [MEANS FOR SOLVING PROBLEMS] Sealing plates (23) to (25) sealing the opening parts of the plurality of gas cylinders (20) to (22) axially stored in cylindrical bodies are broken by moving needle tubes (45), (55), and (56) at a time to blow out a filled gas. Also, the plurality of cylindrical bodies (12) and (13) are connected to each other on a same axis so that one of the cylindrical bodies can be bent or rotated.</p> |
