Most of the commodities are sold with respective outer packages, while larger commodities are placed in the packaging boxes. In the related art, the conventional packing cases are continuously pursued for simpler manufacturing methods and lower production costs, thereby meeting the demands of wholesale sales, but this may result in insufficient protection capability of the packing cases for goods.

The inventor of the present utility model found through researches that in order to make the conventional packing box in a simpler manner, thereby realizing a lower production cost, the conventional packing box is mostly provided as a folding packing box formed by folding a preset paperboard. Although the folding type packing box is simple to manufacture and low in cost, the side wall of the packing box formed by the paperboard enables the packing box to be easily deformed. When the packing box is extruded and collided, the packing box can be easily deformed, so that the protection capability of the packing box on products is weak.

In view of this, the utility model provides a packaging box, which aims to solve the problem that the conventional packaging box has insufficient protection capability on commodities due to pursuing a simpler manufacturing mode and lower production cost. Fig. 1 to 5 are schematic structural views of a packaging box according to the present utility model.

When the inner support 2 is specifically manufactured, the production machine will first fold the four folded portions 324 around the corresponding first folding lines 33 to be perpendicular to the bottom plate 31, and then fold the attaching portions 325 on the two first side plates 321 towards the corresponding folded portions 324. And then, each first redundant part 3211 is folded around a corresponding third folding line 3212 to be perpendicular to the corresponding attaching part 325, and finally, the attaching parts 325 on the two second side plates 322 are folded towards the corresponding folding parts 324, so that the attaching parts 325 on the second side plates 322 and the folding parts 324 clamp the corresponding first redundant parts 3211, and the attaching parts 325 and the folding parts of the second side plates 322 define an energy absorption cavity.

In this embodiment, the planar board 3 of the preset structure is provided with the first redundant portion 3211, so that the inner support 2 can directly form the energy absorption cavity through folding, without being preset in the planar board 3, and therefore, the production of the inner support 2 is simpler and the production cost is lower.
