Storage box having plate-shaped wall structure and capable of being repeatedly disassembled and assembled

A storage box having a plate-shaped wall structure and capable of being repeatedly disassembled and assembled, comprising two first plate-shaped walls (1), two second plate-shaped walls (2), and two third plate-shaped walls (3), wherein each first plate-shaped wall (1) of the two first plate-shaped walls (1) comprises a rectangular first wall body (1a), two opposite side surfaces of the first wall body (1a) are provided with one group of first insertion heads (1b), and another two opposite side surfaces are provided with one group of second insertion heads (1c);

• each second plate-shaped wall (2) of the two second plate-shaped walls (2) comprises a rectangular second wall body (2a), the second wall body (2a) is provided with two groups of first insertion grooves (2b) in one-to-one correspondence to the two groups of first insertion heads (1b) of a corresponding first plate-shaped wall (1), and two opposite side surfaces of the second wall body (2a) are provided with one group of third insertion heads (2c);
• each third plate-shaped wall (3) of the two third plate-shaped walls (3) comprises a rectangular third wall body (3a), the third wall body (3a) is provided with two groups of second insertion grooves (3b) in one-to-one correspondence to the two groups of second insertion heads (1c) of a corresponding first plate-shaped wall (1), and the third wall body (3a) is further provided with two groups of third insertion grooves (3c) in one-to-one correspondence to the two groups of third insertion heads (2c) of a corresponding second plate-shaped wall (2);
• a put-in/take-out opening (4) is formed in the first wall body (1a) of either of the two first plate-shaped walls (1), or in the second wall body (2a) of either of the two second plate-shaped walls (2), or in the third wall body (3a) of either of the two third plate-shaped walls (3);
• when the storage box is in an assembled state, the six plate-shaped walls define a storage space, the two first plate-shaped walls (1) and the two second plate-shaped walls (2) are located between the two third plate-shaped walls (3) disposed in parallel, the two first plate-shaped walls (1) are located between the two second plate-shaped walls (2) disposed in parallel, the two first plate-shaped walls (1) are disposed in parallel, the first insertion heads (1b) of each first plate-shaped wall (1) are inserted into the first insertion grooves (2b) of a corresponding second plate-shaped wall (2), the second insertion heads (1c) of each first plate-shaped wall (1) are inserted into the second insertion grooves (3b) of a corresponding third plate-shaped wall (3), and the third insertion heads (2c) of the second plate-shaped wall (2) are inserted into the third insertion grooves (3c) of a corresponding third plate-shaped wall (3);
• and
• when the storage box is in the assembled state, the two third plate-shaped walls (3) and the two first plate-shaped walls (1), or the two third plate-shaped walls (3) and the two second plate-shaped walls (2) are both connected via unlockable first locking structures (6-1).
