Detailed Implementation

[0030] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0031] Example 1

[0032] Figure 1 This is a structural schematic diagram of an embodiment of the present utility model, as shown below. Figure 1 As shown, the structure of a packaging box that is easy to assemble and disassemble according to an embodiment of the present invention will be described in detail.

[0033] According to an embodiment of the present invention, a packaging box that is easy to assemble and disassemble includes the following structure:

[0034] Please see Figure 4 The upper box body 1 includes an outer edge of the top cover 11 and an inner ring of the top cover 12. The outer edge of the top cover 11 is provided with a plurality of top edge locking tongues 111, preferably six, which extend outward and are provided with top cover protrusions 115 for locking and limiting to prevent the upper and lower boxes from rotating relative to each other. The inner ring of the top cover 12 is located inside the outer edge of the top cover 11 and is provided with an inner ring hook 121 for connecting the lower box body 2 to achieve a fixing function.

[0035] Please see Figure 5 The lower box 2, which cooperates with the upper box 1 to form a closed space, is detachably disposed inside the upper box 1. It includes an outer edge portion 21 of the bottom support and an inner ring portion 22 of the bottom support. The outer edge portion 21 of the bottom support is provided with a plurality of bottom edge grooves 211 that are adapted to the top edge locking tongue 111. Preferably, there are six bottom edge grooves 211 that can be engaged with the top edge locking tongue 111. Extending outward, it is provided with a bottom support protrusion 215 that is adapted to the top cover protrusion 115. The top cover protrusion 115 and the bottom support protrusion 215 are fitted together. The inner ring portion 22 of the bottom support is disposed inside the outer edge portion 21 of the bottom support. The inner ring portion 22 of the bottom support is provided with an inner ring groove 221 that is adapted to the inner ring hook 121. The inner ring hook 121 and the inner ring groove 221 are engaged.

[0036] In this process, the upper box 1 is aligned with the lower box 2, and the top edge locking tongue 111 of the upper box 1 is aligned with the bottom edge groove 211 of the lower box 2. The lower box 2 is then pressed into the upper box 1 axially. The top edge locking tongue 111 engages with the corresponding bottom edge groove 211, and simultaneously, the inner ring hook 121 engages with the corresponding inner ring groove 221. The upper box 1 and the lower box 2 are thus locked together to form an annular cavity for packaging items. This closed structure protects the items from compression and impact, while also limiting their movement.

[0037] Please see Figure 3 , Figure 4 and Figure 5To extend the contact length between the upper and lower boxes, the outer edge of the top cover 11 includes a front extension 112 extending towards the side closer to the lower box 2. The extended end of the front extension 112 has a rear extension 113 perpendicular to its extension direction, thus widening the force-bearing area. The outer edge of the bottom support 21 includes a front extension 212 extending in the same direction as the front extension 112. The extended end of the front extension 212 has a rear extension 213 perpendicular to its extension direction, forming an extension structure adapted to the front and rear extensions of the top cover. As the upper box 1 and lower box 2 are continuously pressed together axially, the front extension 112 and the front extension 212 approach each other, eventually fitting tightly together axially. Similarly, the rear extension 113 and the rear extension 213 approach each other, eventually fitting tightly together in a direction perpendicular to the axial direction.

[0038] Please see Figure 4 and Figure 5 To limit the locking tongue 111 and the bottom groove 211 and prevent the two boxes from rotating relative to each other, a top cover arc edge portion 114 is provided between the two ends of the top cover protrusion 115. The top cover protrusion 115 and the top cover arc edge portion 114 together form a closed shape. A bottom support arc edge portion 214 adapted to the top cover arc edge portion 114 is provided between the two ends of the bottom support protrusion 215. As the top cover front extension portion 112 and the bottom support front extension portion 212, and the top cover outer extension portion 113 and the bottom support outer extension portion 213 are pressed together, the top cover protrusion 115 on the outer edge portion 11 of the top cover of the upper box 1 and the corresponding bottom support protrusion 215 on the outer edge portion 21 of the bottom support of the lower box 2 fit together. At the same time, the top cover arc edge portion 114 also fits together with the bottom support arc edge portion 214.

[0039] Please see Figure 1 To accommodate the shape of ring-shaped or elongated items such as badminton rackets and net strings, the outer edge 11 of the top cover is provided with an arc-shaped protrusion 14. The arc-shaped protrusion 14 extends and protrudes towards the side away from the lower box 2, and its opposite side is recessed to form an upper placement groove 13. The upper placement groove 13 is used to accommodate the upper half of the packaged item. The side of the lower box 2 corresponding to the arc-shaped protrusion 14 is recessed to form a lower placement groove 23. The lower placement groove 23 is used to accommodate the lower half of the packaged item. The lower half of the packaged item, such as a badminton racket or net string, is placed in the lower placement groove 23 of the lower box 2. Align the upper box 1 with the lower box 2 and press them together axially. The upper box 1 and the lower box 2 fit together and are locked in place. The upper placement groove 13 and the lower placement groove 23 together form an annular cavity that is highly adapted to the shape of the packaged item. The upper half of the packaged item is accommodated in the upper placement groove 13 and the lower half is accommodated in the lower placement groove 23. The item is completely wrapped and positioned within the annular cavity.

[0040] Please see Figure 1 In order to engage with the inner ring groove and improve connection stability, the inner ring hook 121 extends and protrudes along the direction of the lower box 2, and its shape is either cylindrical or polygonal.

[0041] Please see Figure 4 and Figure 5 In order to fix the inner ring hook 121 inserted into the inner ring groove 221, a bottom lock buckle 2211 is provided on the outside of the inner ring groove 221 to clamp the inner ring hook 121, which plays a role in preventing the inner ring hook 121 from coming loose due to vibration during transportation or handling, and further strengthens the connection between the upper and lower boxes.

The main focus is on the structure that is different from that in Embodiment 1 of this utility model. The only difference between Embodiment 2 and other embodiments is the way the box is disassembled.

[0044] Please see Figure 6 To facilitate disassembly of the box, an arc-shaped upper outward protrusion 1131 is provided on either side of the top cover extension 113. The upper outward protrusion 1131 extends away from the lower box 2, and a gap is formed between the upper outward protrusion 1131 and the bottom support extension 213. During disassembly, the upper box and the lower box can be separated by inserting into the gap between the upper outward protrusion 1131 and the bottom support extension 213, making the operation quick and easy.
