The invention discloses a centralized box for centralized placement of large-size articles and small-size articles for logistics. The centralized box comprises a centralized box body, a layered assembly is arranged in the centralized box body, and partition plates are arranged on one side of the layered assembly. The centralized box is scientific and reasonable in structure, and safe and convenient to use; the layered assembly is arranged, through the effects of a sliding rod supporting block, a sliding rod and a layering plate, the interior of the centralized box can be conveniently layered,the space pattern inside the centralized box can be changed according to actual requirements, the articles with different sizes can be placed, so that the orderliness of article placement is improved;through the effects of springs, fixing clamps, movable shafts and the anti-skid inner cushions, the layering plate can be conveniently arranged and disassembled; and the partition plates are arranged, through the effects of elastic clamping ball, connecting rods and connecting through holes, the partition plates with different sizes can be conveniently arranged on one side of the layering plate according to requirements to isolate the articles stored in the centralized box, so that collision between different objects in the moving process is avoided, and the safety of the articles is improved.
