Adjustable height stacking box structure

Abstract

This invention relates to an adjustable-height stackable box structure, comprising a box with a bottom surface and a plurality of side surfaces forming an accommodating space. It includes a first side surface and a second side surface arranged opposite each other. Each of the first and second side surfaces has two sets of interlocking units staggered along a vertical direction, such that the first and second interlocking components have different height differences and are arranged on the inside and outside respectively. When the two boxes are stacked, a low-level interlock is formed when the first side surface of the upper box is aligned with the first side surface of the lower box; a high-level interlock is formed when the first side surface of the upper box is aligned with the second side surface of the lower box. This effectively solves the problems of fixed height and unstable stacking of traditional storage boxes.

Claims

1. An adjustable-height stacked box structure, comprising: a box body, which is formed by a bottom surface and a plurality of side surfaces extending vertically from the bottom surface to create an accommodating space, the plurality of side surfaces including a first side surface and a second side surface disposed opposite to each other; wherein, The first side is provided with two sets of engaging units staggered in the vertical direction, including: a first engaging component located on the outer side of the first side and a second engaging component located on the inner side of the first side; the second side is provided with two sets of engaging units staggered in the vertical direction, including: a second engaging component located on the outer side of the second side and a first engaging component located on the inner side of the second side; the characteristic is that the first engaging component and the second engaging component can be correspondingly fitted into each other, and the first engaging component and the second engaging component have different height differences, so that when the two boxes are stacked, when the first side of the upper box is aligned with the first side of the lower box, the first engaging component on the outer side of the upper box and the second engaging component on the inner side of the lower box engage, forming a low-level engagement; when the first side of the upper box is aligned with the second side of the lower box, the first engaging component on the outer side of the upper box and the first engaging component on the inner side of the lower box engage, forming a high-level engagement.

2. The adjustable height stacked box structure as described in claim 1, wherein, The first and second engaging components are each provided with a guide structure to guide the accurate alignment of the engaging components during the stacking process and avoid misalignment or poor engagement.

3. The adjustable height stacked box structure as described in claim 1, wherein, The first engaging component and the second engaging component are each provided with a protruding structure and a groove structure, respectively. The top of the protruding structure is provided with a guide slope, and the entrance of the groove structure is provided with a tapered guide surface, which is used to reduce the alignment error during stacking and improve the engagement smoothness.

4. The adjustable height stacked box structure as described in claim 1, wherein, The side of the box has modular expansion interfaces, which can be equipped with roller brackets, telescopic rods or external hooks to meet the needs of logistics handling and movement.

5. The adjustable height stacked box structure as described in claim 1, wherein, The box has a carrying handle on its side for easy handling and movement.

6. The adjustable height stacked box structure as described in claim 1, wherein, The locking mechanism of the housing is equipped with a locking mechanism to further secure the locking components after locking, preventing them from loosening due to external force.

7. The adjustable height stacked box structure as described in claim 1, wherein, The box has a transparent window on the side, making it easy to observe the contents inside.
