A stackable storage box

Abstract

This utility model discloses a stackable storage box, comprising: a storage box body, an opening at the top of the storage box body, and support structures with staggered side projection positions on opposite side walls of the storage box body. The support structures are formed by inward indentation of a portion of the side wall of the storage box body. When stacked, the support structures allow for horizontal, reverse stacking of another storage box body. The distance between the upper surface of the support structure and the opening of the storage box body is 1 / 10 to 1 / 3 of the height of the storage box body. This stackable storage box, through the design of a distance of 1 / 10 to 1 / 3 of the height of the storage box body between the upper surface of the support structure and the opening of the storage box body, increases the stacking depth of the upper storage box body within the opening of the lower storage box body, thereby improving stacking stability.

Description

Technical Field

[0001] This utility model relates to the field of storage box technology, and in particular to a stackable storage box. Background Technology

[0002] Traditional storage boxes take up too much volume during transportation and placement, increasing transportation costs and space requirements. Therefore, a new type of storage box has emerged that allows for both standard stacking and 180° rotation, as shown in publication number CN203975448U, named a plastic turnover box for staggered stacking and storage. This saves space during transportation and also acts as a protective lid to prevent items from being crushed. However, because the distance between the upper surface of the support pillars on the side walls and the opening of the storage box is small, the boxes are unstable when stacked. When stacked at a high height or used to store large-capacity boxes, they are prone to tipping over due to external forces. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a stackable storage box, comprising:

[0004] The storage box body has an opening at the top and support structures with staggered side projection positions on opposite side walls. The support structures are formed by a portion of the side wall of the storage box body being recessed inward.

[0005] When stacked, the support structure can be used to horizontally and in reverse stack another storage box body;

[0006] The distance L between the upper end of the support structure and the opening end of the storage box body is 1 / 10 to 1 / 3 of the height of the storage box body.

[0007] Preferably, the distance L between the upper end face of the support structure and the opening end of the storage box body is 20mm-140mm.

[0008] Preferably, the support structure includes a first support structure and a second support structure;

[0009] The first support structure is located at two corners on the same side of the storage box body;

[0010] The second support structure is located on the other side of the storage box body, and the two second support structures are spaced apart at non-corner positions.

[0011] Preferably, the cross-section of the first support structure is rectangular, and the cross-section of the second support structure is trapezoidal.

[0012] Preferably, the side wall of the storage box body between the first support structure and the second support structure is provided with a reinforcing structure.

[0013] Preferably, the edges of the first support structure, the second support structure, and the reinforcing structure are chamfered.

[0014] Preferably, the storage box body has a handle structure at the open edge.

[0015] The stackable storage box provided by this utility model has a design where the distance between the upper end of the support structure and the opening end of the storage box body is 1 / 10 to 1 / 3 of the height of the storage box body. This design increases the stacking depth of the upper storage box body within the opening end of the lower storage box body, thereby improving the stability during stacking.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] like Figure 1 , Figure 2 As shown, this embodiment of the utility model provides a stackable storage box, comprising:

[0027] The storage box body 10 is a box structure with an opening at the top. The two opposite side walls of the storage box body 10 are provided with support structures whose side projection positions are staggered. The support structures are formed by a portion of the side wall of the storage box body 10 being recessed inward.

[0028] When stacked, the support structure can be horizontally and reversed to place another storage box body 10; the support structure can use an existing structure, which will not be described in detail here;

[0029] like Figure 6 As shown, the distance L between the upper end face of the support structure and the opening end of the storage box body 10 is 1 / 10 to 1 / 3 of the height of the storage box body.

[0030] The distance between the upper surface of the support structure and the opening end of the storage box body 10 is 1 / 10 to 1 / 3 of the height of the storage box body, including but not limited to 1 / 10, 1 / 5, 4 / 15, and 1 / 3. This ratio is based on the actual height of the storage box body 10. For example, if the height of the storage box body 10 is 200mm, then L can be 20mm-70mm, including but not limited to 20mm, 40mm, and 66mm; if the height of the storage box body 10 is 420mm, then L can be 42mm, 84mm, 100mm, and 140mm.

[0031] When storing unused items, such as Figure 3 As shown, since the support structure is formed by a portion of the side wall of the storage box body 10 being recessed inward, and the support structures of the storage box bodies 10 are the same, several storage box bodies 10 can be stored normally.

[0032] When stacking is required, such as Figure 4 , Figure 5 , Figure 6 As shown, one of the two storage box bodies 10 is horizontally rotated in the opposite direction and placed on the open end of the other storage box body 10. Since the support structure of the same storage box body 10 is staggered and the support structure is formed by a part of the side wall of the storage box body 10 being recessed inward, after rotating 180 degrees in the opposite direction, the upper storage box body 10 can be placed on the support structure of the lower storage box body 10. The figure shows an example of stacking the two storage box bodies 10. The number of stacked storage box bodies 10 can be set to more layers according to actual needs. The stacking principle is the same as the stacking principle of the other storage box body 10, and will not be repeated here.

[0033] The stackable storage box provided in this embodiment of the utility model has a design where the distance between the upper end of the support structure and the opening end of the storage box body 10 is 1 / 10 to 1 / 3 of the height of the storage box body. This design increases the stacking depth of the upper storage box body 10 within the opening end of the lower storage box body 10, thereby improving the stability during stacking.

[0034] In specific implementation, such as Figure 1 , Figure 2 As shown, the support structure includes a first support structure 11 and a second support structure 12. Both the first support structure 11 and the second support structure 12 are columnar structures that protrude from the inner wall of the storage box body 10, formed by the indentation of part of the side wall of the storage box body 10.

[0035] The first support structure 11 is located at two corners on the same side of the storage box body 10, and the cross-section of the first support structure 11 is rectangular.

[0036] The second support structure 12 is located on the other side of the storage box body 10. The two second support structures 12 are spaced apart at non-corner positions, and the cross-section of the second support structure 12 is trapezoidal.

[0037] In this embodiment, a first support structure 11 is set at the corner of one side of the storage box body 10, and two second support structures 12 are set on the other side of the storage box body 10. On the one hand, by setting two support structures at the corner and on both sides, the problem of the storage box easily tipping over when stacked in a misaligned manner can be prevented, and the stability is better.

[0038] In practice, people such as Figure 1 , Figure 2As shown, a reinforcing structure 13 is provided on the side wall of the storage box body 10 between the first support structure 11 and the second support structure 12. The reinforcing structure 13 is formed by a portion of the side wall of the storage box body 10 being recessed inward. Since the two middle side walls of the storage box body 10 have a large area, using only a planar structure would lead to deformation due to internal stress after material cooling during product injection molding. The reinforcing structure 13 reduces this deformation, thus reducing the defect rate. Simultaneously, the reinforcing structure 13 also increases the load-bearing strength of the storage box body 10 at its location, thereby improving product quality.

[0039] In specific implementation, the vertical and horizontal edges of the first support structure 11, the second support structure 12 and the reinforcing structure 13 are chamfered (not marked in the figure). The chamfer design prevents users from being scratched by the right-angled edges during use.

[0040] In specific implementation, such as Figure 1 As shown, the storage box body 10 has two opposing handle structures 14 on the edge of the opening end. The handle structures 14 protrude from the edge of the storage box 10, providing convenience for users to manually move the object.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
