1. A folding box, comprising:
a bottom board comprising two opposite first sides, and two opposite second sides connected between the first sides; two first folding board sets opposite to each other, each first folding board set comprising a first upper folding board and a first lower folding board pivotably coupled to each other; two second folding board sets opposite to each other, each second folding board set comprising a second upper folding board and a second lower folding board pivotably coupled to each other; and a mounting frame comprising two opposite first sidewalls, and two opposite second sidewalls connected between the first sidewalls; wherein a bottom side of each of the second lower folding boards of the second folding board sets is pivotably coupled to a corresponding one of the second sides of the bottom board, each of the first folding board sets is connected between a corresponding one of the first sidewalls of the mounting frame and a corresponding one of the first sides of the bottom board, and sandwiched between the second folding board sets; wherein to adjust a height of the folding box to receive something, the first upper folding board and the corresponding first lower folding board are folded to each other, the second upper folding board and the corresponding second lower folding board are folded to each other; wherein the bottom sides of the first upper folding boards of the first folding board sets are lockable to the opposite first sides of the bottom board respectively, the top sides of the second lower folding boards of the second folding board sets are lockable to the opposite second sidewalls of the mounting frame respectively; and wherein at least two pivot portions are formed from two opposite ends of the bottom side of each second upper folding board of the second folding board sets, to be pivotably connected to the top sides of the corresponding second lower folding board of the second folding board sets, a first locking slot is defined in each second upper folding board of the second folding board sets, a second locking slot is defined in one of the pivot portions of each second upper folding board of the second folding board sets, a block is formed on an inner side of each second sidewall of the mounting frame, the blocks are lockable to the first locking slots respectively, when the second upper folding boards of the second folding board sets are folded to the second lower folding boards of the second folding board sets respectively, the at least two pivot portions are rotated out to make the second locking slots face out, the blocks are lockable to the second locking slots respectively. |
