Abstract:
1. A removable hard drive storage device, comprising: a housing having at least one first partition board, at least one second partition board parallel to the first partition board, wherein the first partition board and the second partition board define an accommodating space having an opening end and a bottom end, the opening end is defined as up and the bottom end is defined as down; a plurality of hard drive casings configured to be slidably accommodated in the accommodating space and each having a tray, a first side plate on one side of the tray and a second side plate at another side of the tray, wherein the tray, the first side plate and the second side plate define a hard drive accommodating slot for accommodating one hard drive, the first side plate and the second side plate are respectively proximal to the first partition board and the second partition board, an upper end of the hard drive casing is formed with an opening, and a cover plate is disposed at the opening; a plurality of guiding units protruding from outer faces of the first side plate and the second side plate, wherein the guiding units are aligned along a length-wise direction of the first side plate and the second side plate; a plurality of guiding grooves formed at the first partition board and the second partition board and corresponding to the positions of the guiding units, wherein the guiding units are configured to slidably engage the guiding grooves; and a plurality of expansion units disposed at two side faces of the first side plate and the second side plate and above the guiding units, wherein a lower end of each of the expansion units is connected to an outer surface of the first side plate or the second side plate, another end of each of the expansion units slantedly extends upward and away from the surface of the first side plate and the second side plate; wherein the expansion units have elasticity, when the hard drive casing is moved upward away from the accommodating space and the height of the expansion unit is greater than upper edges of the first partition board and the second partition board, the expansion units each expand outward through elasticity and abut the upper edge of the first partition board and the second partition board, and the hard drive casing is configured to be safe from moving downward.
