Abstract: The present disclosure pertains to a modular storage box in the technical field of containers. The box includes a bottom plate and a side portion. An edge of the bottom plate is provided with an upward-opening insertion groove, whose side wall includes a first wedge member. A bottom surface of the side portion is provided with an insertion strip, whose lower end side wall includes a second wedge member. During assembly, inserting the strip into the groove causes the second wedge member to deflect outward via wedge-fit interaction with the first wedge member and subsequently rebound to its original position. This locks it against the first wedge member, preventing upward movement, while the groove restricts downward displacement. This vertical bidirectional locking structure significantly enhances the connection strength between the side portion and the bottom plate, thereby greatly improving the overall structural stability and firmness of the modular storage box.

Abstract: The present disclosure describes a pull-out storage box, comprising a pull-out box and a pull-out frame. The frame consists of an upper plate, a lower plate, and a support beam assembly that includes two side beams and two independently disposed rear beams. Insertion grooves are provided at the left, right, and rear ends of both the upper and lower plates. During assembly, inserting the side beams and rear beams into their respective grooves forms an integrated frame structure, on which the pull-out box is seated and can slide. This configuration establishes a support system that distributes bearing points to both sides and the rear, creating a more uniform spatial load-bearing layout. Consequently, it effectively minimizes overall shaking and deformation of the box, thereby significantly enhancing the structural durability and operational stability of the entire pull-out storage system.
