Claims

[Scope of utility model registration request]

The opening of a metal pressure-resistant container containing drugs and pressurizing agents has a rim formed by folding back and tightening the opening at the upper end, a broken part protruding in the center, an upstanding wall near the outer periphery, and a rim around the outer periphery. A ring-shaped elastic body is placed between the groove-like part and the mouth edge of the pressure-resistant container, and the ring-shaped elastic body is crimped and fitted to the metal sealing plate having a groove-like part that folds back the standing wall to form a pressure-resistant part of the metal sealing plate. The main body of the pressure-accumulating fire extinguisher has a siphon tube attached to the outside of the seal-breaking part that protrudes downward inside the container, and has a space in which the injection nozzle and the firing pin communicating with it can descend, and an operating handle can be attached. A three-dimensional part, a flat plate that forms the bottom surface and has a center hole through which the firing pin passes, and an injection part that is a cylindrical part that protrudes from the flat plate on the opposite side of the three-dimensional part and through which the firing pin passes, the cross section of which is an inverted U. When fixing the fixing ring by sandwiching it between the flat plate and the outside of the grooved part of the metal sealing plate, the firing pin that communicates with the injection nozzle is connected to the center hole of the flat plate and the inside of the cylindrical part. , so that the tip of the firing pin is located near the seal-breaking part, and an inverted T-shaped lever-type operating handle is provided on the three-dimensional part of the injection part so that its fulcrum can be rotated at the top of the injection nozzle. The point of action is located at the top of the firing pin, and the lever, which is the point of force, is located above the injection part, and the area other than the injection hole of the injection nozzle and the part where the lever moves is covered with a cap-like cover, and the accumulating pressure is A safety device attached to an accumulator fire extinguisher that has a handle that fits approximately within the outside diameter of the fire extinguisher body above the cap-like cover, and consists of an n-shaped safety plug consisting of two long and short rods and a sloped or arcuate surface. and a locking body that is capable of retracting on the flat plate in the opposite direction to the injection hole, an N-shaped safety plug passes through two places at the top of the handle, and one short rod is connected to the lever. The moving side of the rod touches the lever, and the other long rod passes behind the injection nozzle inside the three-dimensional part of the injection part, passes through the locking body, and when temporarily fixed to the flat plate, the locking body A safety device for an accumulator fire extinguisher, characterized in that a locking body is temporarily fixed on the flat plate so that the slope or arcuate surface contacts the rear lower end of the injection nozzle.
