Description

Corrugated paper packing box with reinforced stacking structure Technical Field The utility model relates to the field of packaging products, in particular to a corrugated paper packaging box with an enhanced stacking structure. Background The corrugated paper packing box is a standardized transport and storage container which is made of corrugated paper board as a base material through the processes of die cutting, indentation, folding, bonding and the like. The connection of the upper and lower layers of the existing corrugated paper box usually depends on simple plane contact or tape winding, and a rigid jogging mechanism is lacked. Under the high-rise stacking or heavy-load scene, the weight of the upper layer packaging box is concentrated on the top surface of the lower layer, so that the top of the lower layer packaging box is concavely deformed, and even the interlocking collapse accident is caused. The side wall of the traditional corrugated case is mostly formed by bending single-layer paperboards, and is easy to fold, bulge and even tear when being vibrated in transportation or manually stacked and extruded, so that internal goods are damaged by impact. Disclosure of utility model The utility model aims to provide a corrugated paper packing box with a reinforced stacking structure, which solves the problems that the traditional corrugated paper box is easy to collapse when being stacked on a high layer and the side wall is easy to deform when being pressed. The corrugated paper packaging box comprises a box body and a box cover, wherein the box body is formed by enclosing a front end plate, a rear end plate, a bottom plate and two side walls to form a containing cavity with an open top, the box cover is rotationally connected to the edge of the open top of the box body, inserting pieces are symmetrically arranged on two sides of the top of the box body, inserting holes are formed in positions, corresponding to the inserting pieces, of the two sides of the top of the box cover, the inserting pieces are configured to be inserted into the corresponding inserting holes when the box cover is closed, after the inserting pieces are inserted into the inserting holes, the ends of the inserting pieces penetrate through the inserting holes and are exposed out of the outer surface of the box cover, positioning holes are symmetrically formed on two sides of the bottom plate of the box body, and the positioning holes are configured to enable the ends of the inserting pieces, exposed out of the outer surface of the box cover, of the packaging box positioned on the upper layer, to be inserted into the positioning holes of the packaging box positioned on the lower layer when a plurality of packaging boxes are stacked and stacked. Preferably, the top edges of the two side walls of the box body are respectively connected with an inner plate bent towards the inner side of the accommodating cavity of the box body, the inner plate is arranged in parallel with the side walls, a double-layer corrugated board structure is formed between the side walls and the inner plate, the lateral extrusion resistance of the side walls is improved, and the side walls are prevented from deforming due to cargo deviation or external force impact in transportation. Preferably, the two side edges of the front end plate and the two side edges of the rear end plate are respectively provided with a paste plate vertically bent towards the inner side of the box body accommodating cavity, the paste plates are inserted into an interlayer gap formed between the side wall and the inner plate, two sides of the paste plates are respectively bonded and fixed with the side wall and the inner plate, and the processing is more convenient by using a bonding mode. Preferably, the waist type hole has all been seted up on two lateral wall surfaces of box body, and the gripping position when waist type hole was carried as the manual work is convenient for two hand-pulled packing box, promotes handling efficiency. Preferably, in the bottom edge of the box cover, except one side rotationally connected with the top of the box body, the edges of the other three sides are all connected with downward perpendicularly bent cover eaves, and the cover eaves can effectively prevent dust, water vapor or foreign matters from entering the box and protect cargoes from pollution.
