DETAILED DESCRIPTION OF THE INVENTION

[0016] The technical solutions in the embodiments of the present invention are clearly and completely described with reference to the drawings in the embodiments of the present invention, and of course, the described embodiments are not all embodiments but only one embodiment of the present invention. Based on the embodiments of the present invention, any other embodiments that can be obtained by those skilled in the art without creative efforts are all within the scope of protection of the present invention.

[0017] Example 1

[0018] Referring to FIGS. 1 to 15, a first embodiment provides a stackable storage basket.

[0019] As shown in Figure 1, the storage basket comprises a storage basket body 5, which comprises side frames 1 and a bottom plate 2. The side frames 1 surround the bottom plate 2 to form a storage compartment 3 for storing items. The bottom plate 2 is attached to the bottom of the side frames 1 and fixedly connected to the side frames 1, improving the stability of the entire structure.

[0020] In this embodiment, the bottom plate 2 and the side frame 1 have a split structure, which is convenient for manufacturing and assembly, and at the same time, it is advantageous for the selection of materials, reducing weight and production costs. The bottom plate 2 is fixed to the bottom of the side frame 1 by welding, which ensures a strong connection and at the same time increases the overall load-bearing capacity.

[0021] Furthermore, in other embodiments, the bottom plate 2 may be integrally formed with the side frame 1 or may be press-formed, thereby shortening the assembly process and improving production efficiency. For example, the bottom plate 2 and side frame 1 structure may be press-formed using a single steel plate or aluminum alloy plate, or the bottom plate 2 and side frame 1 structure may be press-formed using a metal mesh plate, thereby realizing different usage needs and aesthetic effects.

[0022] In this embodiment, an opening is provided at the top of the storage basket main body 5 and is not sealed, so items can be put in and taken out through the top opening.Of course, a plastic plate can be placed on the support part 132 at the top opening of the storage basket main body 5 to seal the top of the storage basket main body 5 and prevent dust and miscellaneous items from entering, making it easier for users to operate it.

[0023] At the same time, when the storage basket bodies 5 are stacked, the bottom of the upper storage basket body 5 can be fitted into the opening of the lower storage basket body 5, and by closing the opening of the lower storage basket body 5, items can be prevented from falling out of the lower storage basket body 5.

[0024] In this embodiment, the side frame 1 comprises a lower connecting plate 11, a middle connecting plate 12 and an upper connecting clamp plate 13 connected in sequence, the lower connecting plate 11 is connected to the bottom plate 2, the upper connecting clamp plate 13 is used to support the upper storage basket body 5, and the middle connecting plate 12 plays the role of a transition connection, making the overall structure of the side frame 1 more stable, and the upper connecting clamp plate 13 comprises an upper connecting part 131 connected to the middle connecting plate 12 and a support part 132 connected to the upper connecting part 131, the support part 132 extending into the storage chamber 3 to support the lower connecting plate 11 of the previous storage basket body 5, realizing a vertical stacking arrangement of multiple storage basket bodies 5. This structural design allows multiple storage basket bodies 5 to be stacked together, saving space and increasing overall flexibility in use.

[0025] To achieve a stable stacking effect, the side frames 1 are inclined, allowing the upper storage basket bodies 5 to naturally align and fit tightly together when placed on top of the lower storage basket bodies 5. Specifically, the upper connecting clamp plate 13 of the side frames 1 is larger than the lower connecting plate 11 at the bottom, and the lower connecting plate 11 of the previous storage basket body 5 is inserted into the upper connecting part 131 of the next storage basket body 5 to create an internal limit, thereby ensuring stability and strength when stacked. Furthermore, the support part 132 of the upper connecting clamp plate 13 has sufficient load-bearing capacity to effectively support the weight of the upper storage basket body 5 and prevent structural deformation or damage due to gravity. This structural design not only increases the overall strength of the storage basket bodies 5 when stacked, but also improves safety and reliability, meeting storage needs in different scenarios. In actual application, the inclination angle of the side frames 1 can be adjusted according to the stacking height of the storage basket bodies 5 to achieve optimal stacking stability and load-bearing capacity.

[0026] Furthermore, in order to make it easier to lift the storage basket body 5 vertically, a handle structure 4 for lifting the storage basket body 5 vertically is provided on the side frame 1, and the handle structure 4 lifts the storage basket body 5 vertically and places it on top of the next storage basket body 5, which is supported by the support part 132.

[0027] The design of the handle structure 4 not only improves the convenience of stacking the storage basket bodies 5, but also helps the user complete the stacking operation more easily by vertically lifting the storage basket body 5 and accurately placing it on the next storage basket body 5, while at the same time reducing misalignment and instability during the stacking process. The installation of the handle structure 4 makes it possible to flexibly combine multiple storage basket bodies 5 and adapt to storage scenarios with different heights and capacity requirements.

[0028] As shown in FIG. 6, in this embodiment, the storage basket body 5 is covered with a flocked layer, and the bottom plate 2 is a rectangular or square metal mesh; in other embodiments, the bottom plate 2 may be a rectangular, square, circular, sector-shaped, or oval metal plate, metal mesh, or wooden plate.

[0029] Furthermore, in this embodiment, the side frame 1 is formed by bending at least one sheet-like metal plate, the connection parts are connected in a ring shape by welding or crimped rivets, and the bottom plate 2 and the side frame 1 are connected by welding.

Specifically, the metal mesh is made of a metal material, such as stainless steel, iron, aluminum, etc., and has a plurality of uniformly distributed meshes, each mesh penetrating the metal mesh. Preferably, in this embodiment, the meshes have a diamond shape. Of course, according to actual needs, the meshes may have different shapes such as rectangles, squares, circles, sectors, hexagons, etc., and are not limited to this embodiment.

[0032] 8, the bottom plate 2 may be provided with a plurality of reinforcing grooves 29 arranged in a horizontal or vertical direction, which can improve the overall strength and carrying capacity of the bottom plate 2 and prevent deformation due to pressure from heavy objects. In a specific implementation, the depth and width of the reinforcing grooves 29 can be reasonably designed according to the use and carrying requirements of the storage basket body 5, thereby achieving both strength and light weight. In addition, the surface of the reinforcing grooves 29 can also have a certain anti-slip property, which can increase the sliding friction of items on the bottom plate 2.

[0033] In this embodiment, as shown in FIG. 6, the cross section of the lower connecting plate 11 is L-shaped, and the lower connecting plate 11 includes a vertical folded edge 112 on the side and a horizontal inner folded edge 111 on the bottom. The peripheral edge of the bottom plate 2 is welded, crimped or riveted to the horizontal inner folded edge 111. The middle connecting plate 12 is formed by bending a metal mesh, and the connecting parts are connected in a ring shape by welding or crimped rivets.
