Abstract: A sprinkler head cover including a housing adapted to be attached to a sprinkler head which is connected to a water supply piping and in which, in the case of fire, a valve disposed inside the sprinkler head is opened to allow a fire-extinguishing liquid in the water supply piping to be dispersed. A cover plate is adapted to cover the sprinkler head so that the sprinkler head cannot be seen from outside, and a mount is installed in the housing and has a hole inside thereof. The cover plate and the mount are connected to each other by a low melting point alloy melted out from the hole, and a heat collector of the sprinkler head has a structure for allowing the heat collector to come into contact with the cover plate.
Abstract: [Problem] An object of the present invention is to provide a sprinkler head cover and a sprinkler head, which can be actuated quickly in case of fire and in which a constant connection strength can be accomplished between the cover plate and the housing without any variations in connection strength exhibited therebetween.
