Description

Technical Field

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

[0002] Cardboard boxes are widely used in product packaging due to their advantages such as low cost, ease of processing, and recyclability. However, the structural design of existing cardboard boxes is mostly based on universality, and the interior is usually a single cavity or divided into several fixed areas by simple partitions, making it difficult to adapt to the storage needs of items with special shapes, especially with obvious defects when placing ring-shaped objects.

[0003] Specifically, ring-shaped objects have a hollow center. If placed directly into the single cavity of a traditional packaging box, they lack a positioning structure specific to their ring shape. During transportation or carrying, they are prone to shaking and collisions, which can easily lead to wear and tear on the object itself and deformation due to the stacking and compression of multiple ring-shaped objects. At the same time, the internal space adjustment performance of existing packaging boxes is poor. The partition positions are mostly fixed designs, making it impossible to flexibly adjust the size of the accommodating area according to the diameter, thickness, and other dimensions of the ring-shaped object. When different sizes of ring-shaped objects need to be placed, it is often necessary to change to packaging boxes of different sizes, which increases packaging costs and reduces packaging efficiency. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing a partitioned cardboard packaging box. The specific technical solution is as follows: A partitioned cardboard packaging box includes a main body. Multiple annular placement grooves are formed at the bottom of the main body. Each annular placement groove has a first annular paper tube on its inner wall, and a second annular paper tube is placed inside the first annular paper tube. Multiple limiting plates are fixedly installed on the inner wall of the top of the main body. A first partitioned inner box, a second partitioned inner box, and a third partitioned inner box are slidably installed between the limiting plates. The inner walls of the first partitioned inner box, the second partitioned inner box, and the third partitioned inner box are all provided with partitioning components to divide the inner box space into multiple independent areas for placing items of different sizes.

[0005] As an improvement to the above technical solution, multiple sets of connecting grooves are provided on the inner walls of the multiple sets of annular placement grooves and the multiple sets of first annular paper tubes, and multiple sets of support plates are fixedly installed on the outer surfaces of the multiple sets of first annular paper tubes and the multiple sets of second annular paper tubes, and the multiple sets of support plates and the multiple sets of connecting grooves are engaged with each other.

[0006] As an improvement to the above technical solution, each of the openings of the annular placement grooves is threaded with an annular cover, the outer diameter of which is adapted to the opening diameter of the annular placement groove, and a handle for easy turning is fixedly installed on the outer surface of the annular cover.

[0007] As an improvement to the above technical solution, the partitioning component includes multiple sets of partition plates fixedly installed on the inner walls of the first partition inner box, the second partition inner box, and the third partition inner box. Each set of partition plates is provided with a card plate, and multiple sets of first card slots are opened on the multiple sets of partition plates. Multiple sets of second card slots are opened on the multiple sets of card plates, and the multiple sets of second card slots and the multiple sets of first card slots engage with each other.

[0008] As an improvement to the above technical solution, the volume of the inner box in the first partition is twice the volume of the inner box in the second partition, and the volume of the inner box in the second partition is twice the volume of the inner box in the third partition.

[0009] As an improvement to the above technical solution, a box lid is slidably installed on the top of the main body of the packaging box.

[0010] The beneficial effects of this utility model are: By utilizing a three-level adaptation structure consisting of a second annular paper tube, a first annular paper tube, and an annular placement groove, the positioning method can be flexibly selected according to the diameter of the annular object. There is no need to equip separate packaging boxes for annular objects of different sizes, which significantly improves the versatility and adaptability of the packaging.

[0011] The tiered volume design of the first, second, and third partition inner boxes allows for flexible selection of the appropriate inner box based on the quantity and volume of items, avoiding space waste and improving overall storage efficiency. The adjustable interlocking structure of the second slot of the card plate and the first slot of the divider allows for quick changes in the internal space partitioning of the inner box, accommodating small items of different sizes and shapes. This enables independent storage of items, facilitating orderly organization and preventing damage caused by friction and squeezing between items, thus enhancing ease of access.

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0015] Example For partitioned cardboard packaging boxes, please refer to... Figures 1-5 The packaging box includes a main body 1. Multiple annular placement slots 11 are formed at the bottom of the main body 1. Each annular placement slot 11 has a first annular paper tube 8 on its inner wall, and a second annular paper tube 81 is placed inside the first annular paper tube 8. The arrangement of the first and second annular paper tubes 8 and 81 provides good support and positioning for the annular object, reducing shaking during storage and transportation. Multiple limiting plates 9 are fixedly installed on the inner wall of the top of the main body 1. A first partition inner box 4, a second partition inner box 5, and a third partition inner box 6 are slidably installed between the multiple limiting plates 9. The inner walls of the first partition inner box 4, the second partition inner box 5, and the third partition inner box 6 are all equipped with partitioning components to divide the inner box space into multiple independent areas for placing items of different sizes.

[0016] like Figure 2-3 As shown, multiple sets of annular placement slots 11 and multiple sets of first annular paper tubes 8 have multiple sets of connecting slots 83 on their inner walls. Multiple sets of support plates 82 are fixedly installed on the outer surfaces of multiple sets of first annular paper tubes 8 and multiple sets of second annular paper tubes 81. The multiple sets of support plates 82 and multiple sets of connecting slots 83 interlock with each other. This structure makes it easier to install and disassemble the first annular paper tubes 8 and the second annular paper tubes 81. At the same time, the interlocking structure ensures that the annular paper tubes will not easily shift during use, enhances the positioning effect of the annular object, and thus improves the stability of the packaging.

[0017] like Figure 1-4As shown, each of the openings of the multiple annular placement grooves 11 is threaded with an annular cover 3. The outer diameter of the annular cover 3 is matched with the opening diameter of the annular placement groove 11, and a handle 31 for easy unscrewing is fixedly installed on the outer surface of the annular cover 3. The matching of the outer diameter of the annular cover 3 with the opening diameter of the annular placement groove 11 ensures the sealing effect. The handle 31 on the outer surface makes it easy for users to unscrew and close the annular cover 3, making the operation simple and effortless, and improving the convenience of use.

[0018] like Figure 2-3 As shown, the partitioning component includes multiple sets of partition plates 71 fixedly installed on the inner walls of the first partition inner box 4, the second partition inner box 5, and the third partition inner box 6. Each set of partition plates 71 is provided with a retaining plate 7. Multiple sets of first retaining slots 72 are opened on the multiple sets of partition plates 71, and multiple sets of second retaining slots 73 are opened on the multiple sets of retaining plates 7. The multiple sets of second retaining slots 73 and the multiple sets of first retaining slots 72 engage with each other. By adjusting the position of the retaining plates 7, the internal space division of the inner box can be changed to meet the storage needs of items of different sizes and shapes. This adjustable structure enhances the versatility of the inner box, improves the space utilization efficiency, and can also prevent items from colliding and squeezing each other, causing damage.

[0019] like Figure 2-5 As shown, the volume of the inner box 4 in the first section is twice the volume of the inner box 5 in the second section, and the volume of the inner box 5 in the second section is twice the volume of the inner box 6 in the third section. The volumes of the inner boxes 4, 5, and 6 in the first section are set in a ratio of 2:1:0.5, which allows for the selection of appropriate inner boxes for storage based on the quantity and volume of items.

[0020] like Figure 1 As shown, a lid 2 is slidably installed on the top of the main body 1 of the packaging box. The lid 2 can seal the top of the packaging box to prevent the contents from falling out, and also to block external debris from entering.

[0021] Working principle: When storing a ring-shaped object, the ring cover 3 is opened along the threaded structure of the ring placement groove 11 by rotating the handle 31, revealing the internal accommodating space. For ring-shaped objects of regular size, they can be directly fitted onto the second ring paper tube 81. The outer peripheral wall of the second ring paper tube 81 and the inner ring of the ring object are used for positioning. When a ring-shaped object with a larger diameter needs to be placed, the second ring paper tube 81 can be pulled outward to disengage the support plate 82 on its surface from the connecting groove 83 on the inner wall of the first ring paper tube 8, and the second ring paper tube 81 can be taken out as a whole. At this time, the ring-shaped object can be directly fitted onto the first ring paper tube 8. If a larger ring-shaped object needs to be placed, the first ring paper tube 8 can be pulled further to disengage the support plate 82 on its surface from the connecting groove 83 on the inner wall of the ring placement groove 11, and the first ring paper tube 81 can be taken out. The inner wall of the ring placement groove 11 is used directly as the positioning structure. The storage needs of ring-shaped objects of different diameters can be met through three-level adaptation adjustment. After placement, the ring cover 3 can be closed by rotating the handle 31 in the opposite direction to achieve sealing protection. For small, non-circular items, they can be placed directly in the first inner box 4, the second inner box 5, or the third inner box 6. Depending on the size of the items, the space can be flexibly divided by adjusting the matching position of the card plate 7 and the divider plate 71. By engaging the second slot 73 of the card plate 7 with the first slot 72 at different positions on the divider plate 71, the spacing between adjacent card plates 7 can be changed, forming multiple independent and variable storage units to accommodate items of different sizes.

[0022] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
