The invention discloses a storage rack, which comprises a base plate (1), a rear baffle plate (1), side baffle plates (3) and a partition board (4), wherein the rear baffle plate (1), the base plate (2) and the side baffle plates (3) are mutually perpendicular to each other; sliding blocks (42) are arranged at the upper and lower ends of the partition board (4); a transverse sliding groove (21) and a longitudinal sliding groove (22) are arranged in the upper plane of the base plate (2); the sliding blocks (42) can slide in the transverse sliding groove (21) and the longitudinal sliding groove(22); and a plurality of grooves (31), which are parallel to the base plate (2), are arranged at the opposite sides of the side baffle plates (3) at intervals, so that the sliding blocks (42) at two ends of the partition board (4) are clamped into the grooves (31). According to the device (the storage rack), the partition board (4) and the base plate (2) can do sliding in transverse direction andlongitudinal direction, so that the position of the partition board (4) can be adjusted in accordance with the amounts of books and materials in practical use. Meanwhile, the partition board (4) can be also inserted into the two side baffle plates (3), so that some materials, which cannot be independently stored, can be placed; and therefore, the storage rack is relatively convenient to use.
