[0028] In this embodiment, the box bottom 1, the two long side panels 3, the two wide side panels 4 and the box cover 5 are all made of PP material. The two long side panels 3 and the two wide side panels 4 are folded on the box bottom 1 by multiple hinges 2, thereby reducing the volume of the entire folding box. When the folding box needs to be unfolded for use, the two long side panels 3 and the two wide side panels 4 are unfolded on the box bottom 1 by multiple hinges 2, and the two long side panels 3 and the two wide side panels 4 are fixed by multiple groups of locking components, so that the box bottom 1, the two long side panels 3 and the two wide side panels 4 cooperate to form a complete box for use; wherein the two long side panels 3 and the two wide side panels 4 are adjacently and symmetrically arranged, and the locking components can be specifically set to four groups, each group of locking components is arranged at the adjacent connection between the two long side panels 3 and the two wide side panels 4, so that the two long side panels 3 and the two wide side panels 4 can be fixed.

[0029] Specifically, each locking assembly includes a first fixing plate 61, a positioning buckle 62, a bayonet 63, a second fixing plate 64, a limiting block 65, a limiting snap ring 66, a limiting protrusion 67 and an opening groove 68. The first fixing plate 61 is fixedly connected to a long side plate 3 of a box, the positioning buckle 62 is fixedly connected to the first fixing plate 61, the bayonet 63 is opened on the positioning buckle 62, the second fixing plate 64 is fixedly connected to a wide side plate 4 of a box and corresponds to the first fixing plate 61, the limiting block 65 is fixedly connected to the second fixing plate 64 and matches the bayonet 63, the limiting snap ring 66 is rotatably connected to the circumferential surface of the positioning buckle 62, the limiting protrusion 67 is fixedly connected to the inner surface of the limiting snap ring 66, the opening groove 68 is opened on the inner surface of the limiting snap ring 66 and corresponds to the limiting protrusion 67, and the opening groove 68 matches the limiting block 65.

[0039] Working principle: two long side panels 3 and two wide side panels 4 are folded on the bottom 1 of the box through multiple hinges 2, thereby reducing the volume of the entire folding box, making it easier to transport and place. When the folding box needs to be unfolded for use, the two long side panels 3 are rotated, and the two long side panels 3 drive the four first fixing plates 61, the four positioning buckles 62 and the four limiting snap rings 66 to rotate, and then the two wide side panels 4 are rotated, and the two wide side panels 4 drive the four second fixing plates 64 and the four limiting blocks 65 to rotate, and the four limiting blocks 65 are respectively rotated into the four bayonet openings 63 and enter respectively. The four opening grooves 68 are formed by rotating the four limiting snap rings 66 on the four positioning buckles 62 respectively. The four limiting snap rings 66 make the four opening grooves 68 and the four limiting blocks 65 misaligned. The four limiting protrusions 67 limit the four limiting blocks 65, so that the four limiting blocks 65 are respectively fixed in the four bayonet holes 63, completing the connection between the four first fixing plates 61 and the four second fixing plates 64, realizing the fixation between the two long side panels 3 and the two wide side panels 4 of the box, so that the box bottom 1, the two long side panels 3 and the two wide side panels 4 of the box cooperate to form a complete box for use.
