[0024] Please see Figures 1 to 8To address the problem of large packaging box volume hindering the storage and transportation of empty boxes, this utility model provides a cylindrical packaging box 100. The cylindrical packaging box 100 is formed by splicing together N equally divided cylindrical components 10, where N ≥ 3. Each equally divided cylindrical component 10 includes a 360 / N° arc-shaped side plate 11 and a cover 20. A strip-shaped sliding bar 113 protrudes from the first free side 111 extending along the axial direction of the cylinder on the arc-shaped side plate 11, and a groove 114 matching the sliding bar 113 is recessed into the second free side 112 extending along the axial direction of the cylinder on the arc-shaped side plate 11. The N equally divided cylindrical components 11 are sequentially spliced ​​together end-to-end via the sliding bar 113 and the groove 114 to form a cylindrical side panel 200. The cover 20 is fixed to the top and / or bottom of the cylindrical side panel 200.

[0025] During assembly, the cylindrical side panel 200 can be spliced ​​simply by aligning the slide bar 113 with the slide groove 114 and pushing it in. The operation is simple, and the individual equally divided cylindrical components 10 can be stacked and stored through the inner side of the arc surface.

[0026] For example, in this embodiment, a diagram is drawn to illustrate N=3. In other embodiments, the cylindrical component 10 can also be made into four equal parts.

[0027] Please see Figure 4 and Figure 7 In one embodiment, each equally divided cylindrical component 10 further includes a fan-shaped base plate 12 integrally formed with the arc-shaped side plate 11. The arc-shaped edge 121 of the fan-shaped base plate 12 is integrally fixed to the arc-shaped side plate 11 at the bottom position of the inner side wall of the arc-shaped side plate 11 to form the overall structure of the equally divided cylindrical component 10. The outer diameter of the fan-shaped base plate 12 matches the inner diameter of the arc-shaped side plate 11 to ensure that the fan-shaped base plate 12 and the arc-shaped side plate 11 fit tightly together, effectively enhancing the stability and load-bearing capacity of the cylindrical packaging box 100.

[0028] Please see Figure 7 In one embodiment, the fan-shaped base plate 12 includes a first radius side 122 near the first free side 111 and a second radius side 123 near the second free side 112. A lower locking edge portion 13 coplanar with the bottom surface of the fan-shaped base plate 12 extends from the first radius side 122, and an upper locking edge portion 14 coplanar with the top surface of the fan-shaped base plate 12 extends from the second radius side 123. This allows the lower locking edge portion 13 to engage with the upper locking edge portion 14 when assembling the cylindrical packaging box 100, thereby achieving the positioning of the equally divided cylindrical components 10 along the length of the cylinder and effectively improving the connection strength between the equally divided cylindrical components 10.

[0029] Furthermore, the length of the upper edge portion 14 is consistent with the length of the second radius side 123, and the length of the lower edge portion 13 is consistent with the length of the first radius side 122. This ensures that the upper edge portion 14 and the lower edge portion 13 can completely cover the corresponding second radius side 123 and first radius side 122, respectively, forming a continuous support surface during splicing, avoiding local stress concentration, and effectively improving the overall stability of the cylindrical packaging box 100.

[0030] Please see Figure 5 , Figure 6 and Figure 7 In one embodiment, the upper retaining edge 14 includes an upper retaining edge (not shown) that protrudes from the sector base plate 12 near the second radius side 123 and is coplanar with the inner surface of the sector base plate 12. The inner surface of the upper retaining edge is higher than the inner surface of the second radius side 123, and an outer step (not shown) is formed on the inner surface of the upper retaining edge and the sector base plate 12. The thickness of the outer step on the inner surface of the sector base plate 12 is the same as that of the lower retaining edge. The lower retaining edge 14 includes a first radius side of the sector base plate 12 near the first free side 111. The lower edge (not shown in the figure) protrudes from the side 122 and is coplanar with the outer surface of the fan-shaped base plate 12. The outer surface of the lower edge is higher than the outer surface of the first radius side 122, and an inner step (not shown in the figure) is formed on the outer surface of the lower edge and the fan-shaped base plate 12. The thickness of the inner step on the outer surface of the fan-shaped base plate 12 is the same as that of the upper edge. The setting of the inner and outer step structures allows adjacent equally divided cylindrical components 10 to fit together when spliced, preventing misalignment and effectively enhancing the sealing performance and structural strength of the cylindrical packaging box 100.

[0031] Please see Figures 1 to 2 In this embodiment, when N equals 3, the angle between the first radius side 122 and the second radius side 123 of the sector base plate 12 at the adjacent side is 120°, and the three equally divided cylindrical components 10 are spliced ​​together to form a cylindrical packaging box 100.

[0032] In another embodiment, when N equals 4, the angle between the first radius side 122 and the second radius side 123 of the sector base plate 12 at adjacent sides is 90°, and the four equally divided cylindrical components 10 are spliced ​​together to form a cylindrical packaging box 100.

[0033] Figures 1 to 2 Taking N=3 as an example, the cylindrical packaging box 100 formed by splicing the equally divided cylindrical components 10 is shown. The cylindrical packaging box 100 provided by this utility model can be flexibly adjusted in size by selecting the number of equally divided cylindrical components 10 as needed.

[0034] Please see Figure 8In this embodiment, the cover 20 may also include a circular top cover (not shown in the figure), which is placed on the top of the cylindrical side panel 200. Specifically, the circular top cover can be fixed by interference fit or snap-fit ​​structure to ensure that the top of the cylindrical side panel 200 is firmly closed.

[0035] It should be noted that in this embodiment, the circular top cover is the cover body 20 itself, and the bottom of the cylinder is sealed to the bottom surface of the cylinder through the fan-shaped bottom plate 12.

[0036] Preferably, in other embodiments, the equally divided cylindrical member 10 does not have a formed fan-shaped bottom plate 12; the cover 20 includes a circular top cover (not shown) and a circular bottom cover (not shown), the circular top cover is placed on the top of the cylindrical side panel 200, and the circular bottom cover is placed on the bottom of the cylindrical side panel 200. The double cover design provides a complete closed space for the cylindrical packaging box 100.

[0037] Please see Figures 5 to 6 In one embodiment, the slider 113 includes a rectangular first strip 1131 protruding from a first free side 111 and a second strip 1132 extending from the top of the first strip 1131 with a circular cross-section; the groove 114 matches the shape of the slider 113.

[0038] When assembling the cylindrical side panel 200, the second strip 1132 is aligned with the circular entrance of the slide groove 114 and pushed in, and then the first strip 1131 is slid into the rectangular channel, thereby achieving a firm connection between the various equally divided cylindrical components 10, effectively improving the smoothness of the splicing and the connection strength of the cylindrical side panel 200.

[0039] Compared with the prior art, the present invention has at least the following technical effects: 1. The cylindrical packaging box 100 provided by this utility model is formed by splicing together N (N≥3) equally divided cylindrical components 10. Each equally divided cylindrical component 10 includes an arc-shaped side plate 11 with a specific arc angle.

[0040] 2. The cylindrical packaging box 100 provided by this utility model has a splicing design, which can divide the empty cylindrical packaging box 100 into multiple equally divided cylindrical components 10, greatly reducing the space occupied and facilitating transportation and storage.

[0041] 3. The cylindrical packaging box 100 provided by this utility model is connected to each equally divided cylindrical component 10 by a slide bar 113 and a slide groove 114, which makes it easy to assemble without the need for additional tools and improves the efficiency of use.
