Description

Technical Field

[0001] This application relates to the technical field of plastic products, and particularly to a plastic storage box. Background Art

[0002] Currently, people generally use storage boxes or storage containers to organize and store items. The most common storage boxes are all square hollow box structures, plus a lid connected movably, to achieve the purpose of storage. However, with the diversification of people's needs, there are more requirements for the functionality of storage boxes. For example, it is required to be able to partition the space inside the box to facilitate the placement of different items.

[0003] Currently, there are some storage boxes with partitions on the market. For example, a Chinese patent with the authorization announcement number CN217779355U and the publication date of November 11, 2022 discloses a storage box, including: a box body, which has a receiving cavity inside; at least two inner walls of the box body are provided with first slots; a positioning member is provided on the bottom plate of the box body, and the center of the positioning member overlaps with the intersection line formed by the extension of two of the first slots into the box; a fixing column, which is detachably connected to the positioning member, and a plurality of second slots are provided on the circumferential side of the fixing column, and the number of second slots on each fixing column corresponds to the number of first slots on the inner wall that can extend to this fixing column; a partition board, both ends of the partition board are inserted into the opposite second slots and first slots or two opposite second slots to divide the receiving cavity into multiple placement spaces.

[0004] In the above, by changing the number and position of the partition boards, the placement space inside the box can be flexibly changed to improve the utilization rate. However, the inventor believes that the partition boards and connectors in this application are fixed inside the box body, which is prone to interference when storing larger-sized objects, and the slots inside the box will also limit the stored items, affecting the use effect; at the same time, the partition boards in this application cannot be used alone.
