[0031] The present invention is described in detail below with reference to the accompanying drawings.

[0032] See also Figures 1 to 5As shown, the utility model is a paper-plastic packaging box with a front and rear packaging structure for a liquid crystal display screen, comprising an outer box 1, a lower supporting structure 2, and an upper supporting structure 3. The outer box 1, the lower supporting structure 2, and the upper supporting structure 3 are all made of paper materials, making the packaging green and environmentally friendly and easy to recycle.

[0033] An accommodating cavity 11 is provided inside the outer box 1. The lower supporting structure 2 and the upper supporting structure 3 are respectively packaged on the front and rear sides of the display screen and arranged in the accommodating cavity 11, which fully wraps and protects the display screen to avoid screen breakage.

[0034] A first buffer cavity 21 is provided at the front end of the lower supporting structure 2 corresponding to the display screen, and multiple first reinforcing structures 22 are provided in the first buffer cavity 21. Second reinforcing structures 23 are provided around the first buffer cavity 21. Through the cooperation of the first buffer cavity 21, the first reinforcing structure 22 and the second reinforcing structure 23, the buffering performance of the lower supporting structure 2 is improved and the protection of the display screen is more comprehensive.

[0035] The upper supporting structure 3 is provided with a second buffer cavity 31 corresponding to the rear end of the display screen. The second buffer cavity 31 is provided with a contact structure 32 that interferes with the rear end of the display screen. The second buffer cavity 31 and the contact structure 32 limit the displacement of the display screen in the package, thereby ensuring the stability of the display screen in the package and reducing the risk of damage caused by vibration and impact during transportation.

[0036] The present application utilizes a lower support structure 2 and an upper support structure 3, respectively packaged on the front and rear sides of the display screen and disposed within a receiving cavity 11. This not only provides the necessary buffer space for the display screen, but also ensures the stability of the display screen within the package through the contact structure 32, reducing the risk of damage caused by vibration and impact during transportation and preventing screen breakage. This packaging structure comprises only three components: the outer box 1, the lower support structure 2, and the upper support structure 3. This simplifies the packaging structure, reduces packaging costs, and improves the packaging's protective properties.

[0037] Preferably, the lower supporting structure 2 and the upper supporting structure 3 are provided with avoidance grooves 4 corresponding to the swing cover of the outer box 1 , so that the swing cover of the outer box 1 can close the accommodating cavity 11 through the avoidance grooves 4 .

[0038] See also Figure 3 As shown, the first reinforcement structure 22 of this embodiment includes a sinking groove 221 , a boss 222 and a reinforcement rib 223 .

[0039] The sinking groove 221 is arranged in the middle of the first buffer cavity 21 . There are multiple bosses 222 , which are evenly spaced in the sinking groove 221 . The reinforcing ribs 223 are arranged between the bosses 222 and the sides of the sinking groove 221 .

[0040] The combination of the sinking groove 221, the boss 222 and the reinforcing rib 223 achieves structural integration and reinforcement of the first reinforcing structure 22, making it more resistant to external impact and pressure.

[0041] The provision of the sinking groove 221 helps to disperse stress to a larger area when subjected to external force, reduce local stress concentration, and reduce the risk of structural damage caused by stress concentration.

[0042] The plurality of bosses 222 are evenly spaced apart in the sinking groove 221 , providing additional support points, thereby enhancing the stability and bearing capacity of the overall structure, and making the structure less likely to deform or fail when subjected to stress.

[0043] The provision of the reinforcing ribs 223 strengthens the connection between the boss 222 and the side of the sinking groove 221, further improving the overall strength and rigidity of the first reinforcing structure 22, and also improving the overall durability, thereby extending the service life of the packaging structure.

[0044] See also Figure 3 As shown, the boss 222 of this embodiment includes a top plane 2221 and a wavy side surface 2222 . The wavy side surface 2222 gradually shrinks toward the center along the height direction, and the top plane 2221 is arranged on the top of the wavy side surface 2222 .

[0045] The design of the wavy side surface 2222 increases the surface area of ​​the boss 222. This design enables the boss 222 to better disperse and transfer stress when subjected to external force, thereby reducing the risk of structural damage.

[0046] The wave side surface 2222 gradually shrinks toward the center along the height direction. This design helps optimize stress distribution and reduce structural damage caused by stress concentration. Through the gradually shrinking side surface, stress can be more evenly distributed on the boss 222 and the first buffer cavity 21.

[0047] The top plane 2221 provides a stable support surface, so that the boss 222 is not prone to tilting or becoming unstable when subjected to external force.

[0048] The design of the wavy side surface 2222 also gives the boss 222 a certain toughness, making it better able to adapt to and resist external shocks and vibrations. This toughness helps to extend the service life of the boss 222 and reduce damage caused by external factors.

[0049] See also Figure 3 As shown, the second reinforcement structure 23 of this embodiment includes a surrounding edge 231 , and the side of the display screen is confined within the surrounding edge 231 , so that the display screen is fixed to the first buffer cavity 21 .

[0050] A cavity 2311 is provided in the perimeter edge 231, and a reinforcement block 2312 is provided in the cavity 2311. The cavity 2311 and the reinforcement block 2312 are combined to further enhance the structural strength of the perimeter edge. The reinforcement block 2312 can fill the cavity 2311 to provide additional support and stability.

[0051] A contact strip 2313 is provided on one side of the peripheral edge 231 close to the first reinforcement structure 22. The contact strip 2313 contacts the side of the display screen, which not only helps to fix the display screen, but also disperses stress when subjected to external force, protecting the display screen from damage.

[0052] See also Figure 3 As shown, the surrounding edge 231 of this embodiment is provided with a notch 2314 for conveniently depressing the display screen, and the display screen is easily taken out from the first buffer cavity 21 through the notch 2314 .

[0053] See also Figure 4 As shown, the present embodiment includes multiple contact structures 32. Providing multiple contact structures 32 increases the number of contact points with the rear surface of the display screen, thereby enhancing the stability and reliability of the connection. This helps ensure a stable connection to the display screen under various usage conditions, preventing loosening or falling off.

[0054] Each contact structure 32 has a contact surface 321 at its end that mates with the rear surface of the display screen. This surface 321 is coated with a scratch-resistant coating. This coating effectively prevents scratches or other damage to the display screen surface caused by the contact structure. This is crucial for protecting the integrity of the display screen and extending its lifespan.

[0055] The anti-scratch coating can be a polymer material such as diamond-like carbon DLC, silicon dioxide SiO2, titanium dioxide TiO2, siloxane, polyolefin resin or silicone masterbatch.

[0056] See also Figure 2 As shown, the upper support structure 3 of this embodiment is provided with a fixing slot 33 for securing accessories on the end facing away from the display screen. This fixing slot 33 allows the upper support structure 3 to securely hold accessories such as a base and cable tie-related equipment. This enhances the stability and functionality of the overall structure, allowing these accessories to be placed and secured in place in an orderly manner, avoiding clutter and potential damage.

[0057] See also Figure 2 and Figure 5As shown, the edge of the upper support structure 3 is provided with a guide structure 34 to facilitate the upper support structure 3 entering the accommodating cavity 11. The guide structure 34 simplifies the process of the upper support structure 3 entering the accommodating cavity 11. The guide structure 34 can serve as a guide tool to help the user easily and accurately insert the upper support structure 3 into the accommodating cavity 11, thereby simplifying the installation process and improving installation efficiency. It also makes the disassembly process easier, making it easier for users to perform maintenance and replacement.

[0058] See also Figure 2 As shown, the fixing slot 33 of this embodiment includes a first limiting slot 331, a second limiting slot 332 and a third limiting slot 333.

[0059] The first retaining slot 331 is used to secure the base, while the second and third retaining slots 332 and 333 are used to secure cable clips, securing display-related accessories. These retaining slots 331, 332, and 333 each securely engage with the accessory, simplifying installation and removal while improving overall reliability and stability.

[0060] See also Figure 5 As shown, the guide structure 34 of this embodiment includes a sloped surface 341 disposed at the top edge of the upper support structure 3. The sloped surface 341 slopes outward along the inner side of the upper support structure 3, so that the edge thickness of the upper support structure 3 is less than the center thickness of the upper support structure 3. The sloped surface 341 provides a gradually changing transition surface, allowing the upper support structure to move smoothly along this transition surface during installation and removal. This design reduces friction and resistance between the upper support structure 3 and the accommodating cavity 11, improving the smoothness of operation.

[0061] See also Figure 1 As shown, the outer box 1 of this embodiment is provided with a hand-grip hole 12 penetrating the accommodating cavity 11 on the side thereof, so that the user can carry the outer box 1 conveniently through the hand-grip hole 12 .
