SPRINGCOOLER OF FUZE TYPE

摘要

The present invention relates to a fuse-type sprinkler which sprays firefighting water while opening a drainage hole by melting a fuse by heat of a fire. Specifically, the fuse-type sprinkler accurately and quickly opens the drainage hole by effectively shrinking a support rings inwards by an inclined portion between a holder and a support protrusion of a body when a balancer is lowered by melting the user by the heat of the fire to effectively contain the fire in an early stage, and prevents leakage of the firefighting water until a firefighting operation is started by completely melting the fuse to prevent the fuse from being cooled without melting to greatly improve operational efficiency of a device.
