If the combination of technical solutions is contradictory or impossible to implement, such a combination should be considered non-existent and not within the scope of protection claimed by this utility model.

[0020] like Figures 1-4 As shown, Figure 1 A three-dimensional structural diagram of the inner box structure; Figure 2 This is a breakdown diagram of the inner box structure. Figure 3 This is a cross-sectional schematic diagram of the inner box structure; Figure 4 for Figure 3 The enlarged view of section B shows the inner box structure, which includes a base plate 1, multiple side plates 2, and multiple curved blocks 3. The side plates 2 are distributed along the outer edge of the base plate 1, and the curved blocks 3 are staggered with the side plates 2. Adjacent side plates 2 are connected by a curved block 3. Specifically, the base plate 1, the side plates 2, and the curved blocks 3 together form a receiving slot 4, into which items can be placed.

[0021] Please refer to the following: Figure 5 As shown, Figure 5 for Figure 2 Enlarged view of section A. The base plate 1 has a notch 11, and the arc-shaped block 3 is set within the notch 11. Specifically, the base plate 1 has four notches 11, which are located at the four corners of the base plate 1.

[0022] Please refer to the following: Figure 6 and Figure 7 As shown, Figure 6 This is a schematic diagram of the three-dimensional structure of side plate 2; Figure 7 This is a three-dimensional structural diagram of the arc-shaped block 3. The side plate 2 has a first slot 21 located on one side of the side plate 2. The arc-shaped block 3 has an extension 31 that fits into the first slot 21. In use, the extension 31 is inserted into the first slot 21, thus connecting the side plate 2 and the arc-shaped block 3. In specific applications, extensions 31 are provided on both adjacent sides of the arc-shaped block 3, and each extension 31 is inserted into the first slot 21 of one side plate 2, thus connecting two adjacent side plates 2 and the arc-shaped block 3. In this embodiment, two side-by-side extensions 31 form a group, both inserted into a single first slot 21. To improve the stability of the connection between the arc-shaped block 3 and the side plate 2, two sets of extensions 31 are provided on one side of the arc-shaped block 3. Correspondingly, one side of one side plate 2 has two first slots 21, and the two sets of extensions 31 are respectively inserted into the two first slots 21.

[0023] Furthermore, each extension 31 has multiple protrusions 32 on its outer surface, arranged sequentially on the outer surface of the extension 31. An acute angle exists between the protrusions 32 and the outer surface of the extension 31. Specifically, the cross-section of the multiple protrusions 32 is barbed, and during use, all protrusions 32 abut against the inner wall of the first slot 21, thus improving the connection stability between the extension 31 and the first slot 21.

[0024] Furthermore, the arc-shaped block 3 has a first plane 33, a second plane 34, and an arc surface 35. The first plane 33 is connected to the second plane 34, and the arc surface 35 is connected to both the first plane 33 and the second plane 34. Simultaneously, the arc surface 35 is also joined to the outer surfaces of two adjacent side plates 2. Multiple extensions 31 are respectively disposed on the first plane 33 and the second plane 34. The first plane 33 and the second plane 34 abut against the two walls of the notch 11. In other words, the structure of the notch 11 provides space for the arc-shaped block 3 to be installed. Thus, after the first plane 33, the second plane 34, and the notch 11 are fitted together, the arc surface 35 and the outer surface of the side plate 2 can form a continuous external structure, making the entire inner box structure more aesthetically pleasing and more in line with conventional usage habits. In this embodiment, the included angle between the first plane 33 and the second plane 34 is a right angle.

[0025] The side plate 2 also has a second slot 22, in which the base plate 1 is secured. This not only facilitates the installation of the base plate 1 but also improves the tightness of the connection between the base plate 1 and the side plate 2. In this embodiment, the opening direction of the second slot 22 is parallel to the opening direction of the first slot 21.

[0026] The inner box structure also includes a face frame 5, which is disposed on the top surface of multiple side panels 2. Furthermore, a retaining strip 51 is provided on one side of the face frame 5, and a third retaining groove 23 is provided on the top of the side panel 2. The retaining strip 51 of the face frame 5 can be directly engaged in the third retaining groove 23. In addition, the inner box structure also includes a fixing strip 6, which has a fixing groove 61. The fixing strip 6 is located in the third retaining groove 23, and the opening direction of the fixing groove 61 is the same as the opening direction of the third retaining groove 23. The retaining strip 51 on the face frame 5 is engaged in the fixing groove 61.

[0027] The side panel 2 also has a fourth slot 24, which is located at the bottom of the side panel 2. The inner box structure also includes a bottom frame 7, which is fitted into the fourth slot 24 at the bottom of the multiple side panels 2.

[0028] The design of the front frame 5 and the bottom frame 7 not only enhances the aesthetics of the inner box structure, but also protects the top and bottom of the side panel 2.

[0029] Preferably, the inner box structure further includes a partition 8, which is disposed within the receiving groove 4. The partition 8 can be connected to the side plate 2, the bottom plate 1, or both. The partition 8 divides the space within the receiving groove 4. During use, the partition 8 can be appropriately arranged according to the required space distribution to partition off the desired space within the receiving groove 4. In specific use, the number of partitions 8 can be multiple, such as two, three, or more.

[0030] It should also be noted that, in this embodiment, the base plate 1 has a rectangular structure, and there are four side plates 2, which are located on the four sides of the base plate 1. There are also four arc-shaped blocks 3, with one arc-shaped block 3 connecting two adjacent side plates 2. Furthermore, the structures of the multiple side plates 2 are identical, so the structure of each side plate 2 will not be described in detail here; similarly, the structures of the multiple arc-shaped blocks 3 are also identical, so the structure of each arc-shaped block 3 will not be described in detail here. The face frame 5 can be an integral structure or a split structure. If a split structure is used, there are four face frames 5, each installed on the top of one side plate 2. Correspondingly, there are also four fixing strips 6, each fixedly installed in the third slot 23 of one side plate 2. The bottom frame 7 can be an integral structure or a split structure. If a split structure is used, there are four bottom frames 7, each corresponding to a fourth slot 24 at the bottom of one of the four side plates 2.

[0031] In summary, the splicing method between multiple arc-shaped blocks 3 and multiple side plates 2 changes the traditional integrated structure. Firstly, it can improve the problem of poor mold versatility and reduce precision requirements; secondly, it can improve process flexibility and reduce material requirements; and thirdly, it can increase the fault tolerance rate and improve the yield rate.

[0032] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
