Abstract: A fire extinguisher box is composed of a box body in which a base frame and a link mechanism are mounted. The base frame is fastened pivotally with a seat for locating the fire extinguisher in the box body. The link mechanism is composed of an upright rod fastened with the base frame, a first link rod fastened with the upright rod, and a second link rod coupled with the first link rod and a pull rod of a door of the box body. As the door of the box body is opened, the link mechanism is actuated by the pull rod such that the base frame is driven by the link mechanism to locate at an inclined position, thereby causing the fire extinguisher to locate likewise so as to enable a person to remove the fire extinguisher from the box body easily and quickly.
