Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard box technology, and in particular to a corrugated cardboard box that is easy to assemble and disassemble. Background Technology

[0002] Currently, corrugated cardboard boxes are a common packaging container widely used in logistics, transportation, product packaging, and warehousing. Traditional corrugated cardboard boxes often use tape sealing or simple tongue-and-groove structures for sealing, which, while cost-effective, presents many inconveniences in practical use.

[0003] This utility model, disclosed in announcement number CN221069138U, discloses a corrugated cardboard box that is easy to assemble and disassemble, relating to the field of corrugated cardboard boxes. It includes a base, a box body fitted onto the outer wall of the base, a connecting frame fixedly connected to the outer wall of the base, the connecting frame fitted onto the outer wall of the box body, a mounting frame fixedly connected to the upper end of the outer wall of the box body, the upper end of the connecting frame penetrating the mounting frame, a fixing component fixedly connected to the upper end of the connecting frame, and a limit cover fitted onto the upper end of the connecting frame through the fixing component. The lower end of the limit cover is fitted to the upper end of the mounting frame. This utility model, using the above structure and setting a base, protects the bottom and sides of the box body, allowing the box body to be disassembled while increasing its strength and reducing the risk of deformation or bending that could affect normal use. Simultaneously, the coordinated arrangement of the connecting frame and the mounting frame ensures a stable connection between the base and the box body, resulting in better overall stability of the cardboard box.

[0004] However, in actual use, cardboard boxes sealed with tape often require tools such as scissors and utility knives to open, which is not only cumbersome but also poses a risk of scratching the contents or the user. Secondly, most cardboard boxes with simple interlocking flaps have poor sealing stability and are prone to loosening or even opening during transportation due to bumps, affecting the reliability of the packaging. In addition, although some cardboard box designs that facilitate opening exist, such as those with pre-installed tear strips, their functions are relatively limited, focusing only on ease of opening. They are still insufficient in terms of quick assembly, secure closure, and ease of carrying, making it difficult to meet users' overall packaging experience needs. Utility Model Content

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to solve the shortcomings of the existing technology, such as cumbersome operation and scratching of the contents, and to provide a corrugated cardboard box that is easy to disassemble and assemble.

The inner wall of the connecting groove 8 is engaged with the outer surface of the retaining plate 4. A fixing groove 5 is formed on the outer surface of the cardboard box body 1. A rigid plastic plate 10 is provided on the outer surface of the cardboard box body 1. A fixing block 11 is fixedly connected to the outer surface of the rigid plastic plate 10. The outer surface of the fixing block 11 is engaged with the inner wall of the fixing groove 5. A second retaining groove 13 is formed on the outer surface of the rigid plastic plate 10. A second retaining block 12 is fixedly connected to the outer surface of the rigid plastic plate 10. The inner wall of the second retaining groove 13 is engaged with the outer surface of the second retaining block 12. A first retaining groove 7 is formed on the outer surface of the cardboard box body 1. A first retaining block 6 is fixedly connected to the outer surface of the second top plate 3. The inner wall of the first retaining groove 7 is engaged with the outer surface of the first retaining block 6.

[0031] In this embodiment, the first slot 7 engages with the first slot block 6 to bend the first top plate 2 and the second top plate 3, ensuring a tighter connection at the bend and preventing the top plate from separating from the cardboard box body 1. After the first top plate 2 and the second top plate 3 are closed, the slot 4 engages with the connecting groove 8, increasing the contact area between the first top plate 2 and the second top plate 3. Then, the fixing block 11 engages with the fixing groove 5, connecting the rigid plastic plate 10 to the cardboard box body 1, ensuring it does not separate when lifted. Finally, the second slot block 12 engages with the second slot 13 to bend the rigid plastic plate 10, further ensuring a tighter connection at the bend.

[0032] refer to Figures 1-5 The outer surface of the first top plate 2 is provided with a through hole 9. The outer surface of the hard plastic plate 10 is fixedly connected with a sliding frame 16. The sliding frame 16 is slidably connected to the through hole 9. The inner wall of the sliding frame 16 is fitted with a sliding rod 15. One end of the sliding rod 15 is fixedly connected with a pressing plate 14. One end of the sliding rod 15 is fixedly connected with a flexible plastic plate 17.

[0034] Working principle: Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, when assembling a corrugated cardboard box, firstly, the first top plate 2 and the second top plate 3 are connected to the cardboard box body 1 by engaging the first slot 7 with the first locking block 6. At this time, the two top plates can be bent towards the cardboard box body 1 to complete the initial preparation for closure. Next, the locking plate 4 is inserted into the connecting slot 8 to tightly connect the first top plate 2 and the second top plate 3 together, thereby closing the cardboard box body 1. Then, the fixing block 11 on the rigid plastic plate 10 is aligned with the fixing slot 5 of the cardboard box body 1 and engaged to firmly fix the rigid plastic plate 10 to the cardboard box body 1. Then, the rigid plastic plate 10 is bent, and the engagement of the second slot 13 with the second locking block 12 ensures a tight connection at the bend and that the rigid plastic plate 10 will not break. At the same time, the sliding frame 16 is aligned with the through hole 9 on the first top plate 2 and inserted to make the rigid plastic plate 10 fit against the top plate. After pressing the flexible plastic plate 17 to fit it, insert it into the slide frame 16. Then push the slide rod 15 to slide inside the slide frame 16. When the flexible plastic plate 17 passes through the slide frame 16, it rebounds, ensuring that the hard plastic plate 10 is tightly connected to the top plate, which further fixes and limits the two top plates.

[0035] When disassembling the corrugated cardboard box, first pull the pressing plate 14 forcefully to move the sliding rod 15, pulling the flexible plastic plate 17 out of the sliding frame 16, thus separating the rigid plastic plate 10 from the top plate. Then, release the engagement between the fixing block 11 on the rigid plastic plate 10 and the fixing groove 5 of the cardboard box body 1, and remove the rigid plastic plate 10. Next, pull the clamping plate 4 out of the connecting groove 8, separating the first top plate 2 and the second top plate 3. Finally, release the engagement between the first clamping groove 7 and the first clamping block 6, separating the first top plate 2 and the second top plate 3 from the cardboard box body 1, completing the disassembly of the entire corrugated cardboard box.
