Reinforcing type packaging box

The invention discloses a reinforcing type packaging box. Reinforcing columns are arranged at the connecting parts of every two adjacent parts of cover walls and are fixed with cover walls on two sides; and platy connecting ribs in parallel with the reinforcing columns are arranged between the two cover walls. The reinforcing columns directly enhance the longitudinal stressed structure of the packaging box cover, and the cover walls are fixed through the platy connecting ribs to prevent the cover walls from deformation, so that the compressive strength of the packaging box cover is improved. The support seats of a base are composed of a plurality of corrugated plates; a gap is reserved between every two adjacent support seats, and gaps are reserved for the positions, corresponding to the reinforcing columns on the box cover, of the support seats, so that the stable base is provided for the box cover, and the packaging box is stressed more uniformly during stacked. 种加强型包装箱，在盖壁两两相邻接的连接处设置加强柱，加强柱与两侧的盖壁相固定，在两盖壁之间
