[0020] As Figures 1 to 4 shown, the present utility model discloses a packing box structure with a storage and classification function, including a box body 1. A lid body 2 that can be opened is covered on the top of the box body 1. The lid body 2 is fixed to the box body 1 by the friction generated by contact. A cavity is provided inside the box body 1. A bottom box 3 is provided in the cavity. The bottom box 3 is fixed to the inner wall of the box body 1. A first storage cavity 31 for storing items is provided in the bottom box 3. An expansion box assembly is symmetrically provided above the bottom box 3. The expansion box assembly includes an upper outer box 4 and a lower outer box 5. A second storage cavity 41 and a third storage cavity 51 are respectively provided in the upper outer box 4 and the lower outer box 5. The upper outer box 4 and the lower outer box 5 are rotated to open or close the second storage cavity 41 and the third storage cavity 51 respectively. The space between the inner wall of the box body 1 and the bottom box 3 serves as a fourth storage cavity. The first storage cavity 31, the second storage cavity 41, and the third storage cavity 51 are formed inside the upper outer box 4, the lower outer box 5, and the bottom box 3 and are independent of each other. And the fourth storage cavity formed between the inner wall of the box body 1 and the bottom box 3 can classify and store items, improving the organization when storing items. In addition, the upper outer box 4 and the lower outer box 5 are provided with a rotation and unfolding structure, which can improve the space utilization rate of the inner cavity of the box body 1.

[0021] In this embodiment, a first mounting bracket 32 is fixed to the outer wall of the bottom box 3, and second mounting brackets 42 and third mounting brackets 52 are respectively fixed to the outer walls of the upper outer box 4 and the lower outer box 5. A first connecting rod 6 and a second connecting rod 7 are provided outside the bottom box 3. Two ends of the first connecting rod 6 are respectively rotatably connected to the first mounting bracket 32 and the second mounting bracket 42, and the middle of the first connecting rod 6 is rotatably connected to the third mounting bracket 52. Two ends of the second connecting rod 7 are respectively rotatably connected to the first mounting bracket 32 and the third mounting bracket 52. The arrangements of the first mounting bracket 32, the second mounting bracket 42 and the third mounting bracket 52 facilitate the connection of the first connecting rod 6 and the second connecting rod 7 and ensure the stability of the connection between the first connecting rod 6 and the second connecting rod 7. The first mounting bracket 32, the second mounting bracket 42 and the third mounting bracket 52 are all made of plastic material and are fixed by bonding. When classifying and storing items, by pulling the upper outer box 4 outwards, the connection between the first connecting rod 6 and the first mounting bracket 32 can rotate around the rotation center. Since the center of the first connecting rod 6 is connected to the lower outer box 5, the lower outer box 5 can be driven to rotate outwards around the connection between the second connecting rod 7 and the first mounting bracket 32, so that the second storage cavity 41 and the third storage cavity 51 can be opened simultaneously, making the opening of the second storage cavity 41 and the third storage cavity 51 more convenient and fast.

[0022] In this embodiment, a synchronous gear 8 is further provided at the junction of the second connecting rod 7 and the first mounting bracket 32. The two synchronous gears 8 on both sides are meshed with each other. When pulling the upper outer box 4 on one side outwards to drive the lower outer box 5 to rotate outwards around the connection between the second connecting rod 7 and the first mounting bracket 32, the synchronous gear 8 on this side can be driven to rotate. With the rotation of the synchronous gear 8 on this side, the synchronous gear 8 on the other side can be driven to rotate, so that the expansion box components on both sides can rotate and expand synchronously, and further make the opening of the second storage cavities 41 and the third storage cavities 51 on both sides more convenient and fast.

[0023] In this embodiment, a fence 9 is further provided on the outer periphery of the bottom box 3. The fence 9 is fixed to the inner wall of the box body 1. When storing items in the fourth storage cavity, the fence 9 can separate the items from components such as the synchronous gear 8, so as to avoid interference with the second storage cavity 41 and the third storage cavity 51.

[0024] In this embodiment, when the second storage cavity 41 is opened, the bottom of the upper outer box 4 abuts against the top of the box body 1. In this way, the box body 1 can provide certain support for the upper outer box 4 to ensure the stability after the opening of the second storage cavity 41 and the third storage cavity 51.

[0025] This specific embodiment is only an interpretation of the present utility model and does not limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment that do not contribute creatively as needed, but as long as they are within the scope of the claims of the present utility model, they are protected by the patent law.
