Storage box

A storage box comprising at least one storing unit including:

• a main box that is elongated in a longitudinal direction, and that includes
• a main box body defining a dividable space that has an upward-facing top opening, and
• two first engaging subunits spaced apart from each other in a transverse direction which is perpendicular to the longitudinal direction, and formed on a top end of said main box body, each of said first engaging subunits including a plurality of spaced-apart first engaging members that are arranged in the longitudinal direction;
• and
• at least one dividing plate that has
• a plate body disposed removably in said dividable space and dividing said dividable space into two storage areas, and
• two second engaging members opposite to each other in the transverse direction, respectively connected to two opposite ends of said plate body, and respectively and separably engaging one of said first engaging members of one of said first engaging subunits and one of said first engaging members of the other one of said first engaging subunits;
• wherein said main box body of said main box has
• a main base wall that has two first edges opposite to each other in the transverse direction, and
• two first side walls that extend upwardly and respectively from said first edges of said main base wall;
• wherein each of said first engaging subunits is formed on a top end of a respective one of said first side walls;
• wherein each of said first side walls has a first top surface that faces away from said main base wall, and a first inner lateral surface that extends downwardly from said first top surface and that faces said dividable space;
• wherein, for each said first engaging subunit, each of said first engaging members is an indentation formed in an intersection of said first top surface and said first inner lateral surface of the respective one of said first side walls;
• wherein said second engaging members of said at least one dividing plate are respectively connected to opposite ends of a top portion of said plate body, each of said second engaging members being a protrusion;
• wherein each of said first side walls of said main box body further has a slide groove that is indented at a bottom portion of said first inner lateral surface and that extends in the longitudinal direction;
• and
• wherein said at least one dividing plate further has two sliding members that protrude respectively from opposite ends of a bottom portion of said plate body, each of said sliding members engaging rotatably and being slidable along said slide groove of a respective one of said first side walls so that said at least one dividing plate is rotatable and linearly movable relative to said main box body when said second engaging members are separated from said first engaging members of said first engaging subunits.
