Description

Technical Field

[0001] This utility model relates to the field of folding cardboard box technology, specifically a corner-reinforced cardboard box that can be quickly assembled. Background Technology

[0002] Cardboard boxes, as packaging containers made primarily of corrugated cardboard, are an indispensable cornerstone of modern logistics and commerce. Their structure typically consists of a linerboard and a corrugated core bonded together. This unique construction gives them excellent physical properties, and the internal cavity effectively cushions impacts, ensuring the safety of contents during transport. From an environmental perspective, cardboard boxes are primarily made of renewable wood fiber, possessing recyclable and biodegradable properties, which aligns perfectly with the concept of sustainable development. Their high cost-effectiveness, ease of printing, and flexibility in customization make them extremely versatile, ranging from e-commerce parcels for daily consumer goods and the transportation and turnover of food and beverages to the precision protection of electronic products and even as a carrier of creative marketing—cardboard boxes are ubiquitous.

[0003] To save storage space, some cardboard boxes need to be stacked. However, cardboard boxes have limited compressive strength, especially those at the bottom, which are prone to deformation, causing the entire stack to collapse. Unstable stacking and uneven stacking can also lead to uneven stress on the cardboard boxes, resulting in deformation and collapse. Utility Model Content

[0004] To address the aforementioned issues, this application provides a corner-reinforced cardboard box that can be quickly assembled, solving the problem of cardboard boxes collapsing due to insufficient compression resistance or improper placement.

[0005] A corner-reinforced carton that can be quickly assembled includes a bottom plate, a side guard inserted into the top of the bottom plate, and a reinforcing ring snapped into the top of the side guard for reinforcing its top strength and correcting its shape; Four L-shaped reinforcing strips are inserted between the reinforcing ring and the side guard to reinforce the side corners of the side guard; Limiting groove blocks are fixedly installed on the outer side of the L-shaped reinforcing strip, and restraint straps that reduce bending of the L-shaped reinforcing strip are installed on the outer side of the limiting groove blocks.

[0006] Preferably, the bottom plate has a lower insertion groove at the top that engages with the L-shaped reinforcing strip, and the reinforcing ring has an upper insertion groove at the bottom that engages with the L-shaped reinforcing strip.

[0007] Preferably, the bottom of the reinforcing ring has a mating groove that engages with the top of the side guard.

[0008] Preferably, the bottom of the base plate is provided with a transport groove.

[0009] Preferably, the top of the transport trough is connected to a bundling trough.

[0010] Preferably, a cover plate is slidably installed on the outer side of the reinforcing ring.

[0011] Preferably, the top of the cover plate is fixedly installed with multiple limiting posts, and the bottom of the base plate is provided with multiple limiting holes, with the limiting posts and limiting holes being inserted and matched.

[0012] The beneficial effects of this utility model are as follows: The present invention describes a corner-reinforced cardboard box that can be quickly assembled. The top of the side panel is provided with a reinforcing ring, which makes the top of the side panel less prone to deformation. Workers can put goods into the side panel, especially goods whose size is not much different from the opening size of the top of the side panel, thus improving the placement efficiency. The L-shaped reinforcing strip and reinforcing ring improve the impact resistance of the side panel. The L-shaped reinforcing strip can also improve the vertical compression resistance of the side panel, so that more layers of cardboard boxes can be stacked. When the goods are heavy, the staff use restraint straps to wrap around the outside of the limiting groove block, and use Velcro or tightening device to tighten the restraint straps, so that the L-shaped reinforcing strip is not easy to bend or deform outward, further improving the vertical compression resistance of the carton. During stacking, the upper limiting hole is inserted into the lower limiting post, which makes the weight of the carton more uniform, resulting in neat and stable placement. The bottom carton is subjected to more uniform force, reducing the possibility of the side panels bending or deforming under force. Attached Figure Description

[0016] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the present utility model will be briefly introduced below in conjunction with the accompanying drawings and descriptions of the embodiments or the prior art. Obviously, the following description of the structure of the accompanying drawings is only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is used to help understand this utility model, but does not constitute a limitation on this utility model.

[0017] like Figure 1 , Figure 2 , Figure 5 As shown, this utility model embodiment provides a corner-reinforced carton that can be quickly assembled, including a base plate 1, a side baffle 2 inserted into the top of the base plate 1, and a reinforcing ring 11 for reinforcing its top strength and correcting its shape, which is snapped into the top of the side baffle 2. The bottom of the reinforcing ring 11 is provided with a mating groove 12 that engages with the top of the side baffle 2, so that the connection between the reinforcing ring 11 and the top of the side baffle 2 is more stable.

[0018] Furthermore, such as Figure 2 , Figure 4 As shown, four L-shaped reinforcing strips 4 are inserted between the reinforcing ring 11 and the side guard 2 to reinforce the side corners of the side guard 2. The bottom plate 1 has a lower insertion groove 10 that is inserted and matched with the L-shaped reinforcing strips 4 at the top, and the reinforcing ring 11 has an upper insertion groove 13 that is inserted and matched with the L-shaped reinforcing strips 4 at the bottom, so that the connection between the top of the reinforcing ring 11 and the L-shaped reinforcing strips 4 is more stable.

[0019] In this embodiment, during assembly, the worker first inserts the side panel 2 into the base plate 1, then inserts four L-shaped reinforcing strips 4 into the lower insertion slot 10, then inserts the mating slot 12 of the reinforcing ring 11 into the top of the side panel 2, and inserts the top of the four L-shaped reinforcing strips 4 into the upper insertion slot 13. Goods are then stacked onto the side panel 2, and finally the top of the reinforcing ring 11 is sealed with the cover plate 3. The reinforcing ring 11 makes the top of the side panel 2 less prone to deformation, allowing the worker to place goods into the side panel 2, especially goods with a similar opening size to the top of the side panel 2, thus improving placement efficiency. The L-shaped reinforcing strips 4 and the reinforcing ring 11 enhance the impact resistance of the side panel 2, and the L-shaped reinforcing strips 4 also enhance the vertical compressive strength of the side panel 2, allowing for the stacking of more layers of cardboard boxes.

[0020] Furthermore, such as Figure 1 As shown, a limiting groove block 5 is fixedly installed on the outer side of the L-shaped reinforcing strip 4. A restraint strap to reduce bending of the L-shaped reinforcing strip 4 is installed on the outer side of the limiting groove block 5. Velcro is installed at both ends of the restraint strap, or a tightening device is installed together to tighten the restraint strap. This is a relatively mature existing technology.

[0021] In this embodiment, when the weight of the goods is large, the staff uses a restraint strap to wrap around the perimeter of the limiting groove block 5, and uses Velcro or a tightening device to tighten the restraint strap, so that the L-shaped reinforcing strip 4 is not easy to bend or deform outward, further improving the vertical compressive strength of the carton.

[0022] Furthermore, such as Figure 3 As shown, the bottom of the base plate 1 is provided with a transport groove 8, which facilitates the movement of cartons using tools such as forklifts and improves the transfer efficiency.

[0023] In this embodiment, workers use forklifts or other tools to move goods by inserting them into the handling trough 8, thereby increasing the speed of goods transfer and stacking.

[0024] Furthermore, such as Figure 1 , Figure 3 As shown, a cover plate 3 is slidably installed on the outer side of the reinforcing ring 11 to seal the top of the side guard 2. A bundling groove 9 is opened at the top of the transport trough 8 for placing packing straps. Workers use a packing machine to wrap the packing straps around the bottom plate 1, side guard 2, and cover plate 3. The packing straps are inserted into the bundling groove 9. When the moving mechanism of forklifts and other equipment is inserted into the transport trough 8, it will not touch the packing straps, effectively preventing damage to the packing straps during the transfer process.

[0025] In this embodiment, the staff uses a packing machine to wrap the packing strap around the base plate 1, side guards 2, and cover plate 3. The packing strap is inserted into the bundling groove 9. When the moving mechanism of the forklift or other equipment is inserted into the handling groove 8, it will not touch the packing strap, effectively preventing the packing strap from being damaged during the transfer process.

[0026] Furthermore, such as Figure 1 , Figure 3 As shown, multiple limiting posts 6 are fixedly installed on the top of the cover plate 3, and multiple limiting holes 7 are opened at the bottom of the base plate 1. The limiting posts 6 and limiting holes 7 are inserted and matched to limit the placement position of the carton.

[0027] In this embodiment, during stacking, the upper limiting hole 7 is inserted into the lower limiting post 6, which makes the weight of the carton more uniform, neat and stable, and the bottom carton is subjected to more uniform force, reducing the possibility of the side guard 2 bending or deforming under force.

[0028] Specific working methods: During assembly, the workers first insert the side panel 2 into the base plate 1, then insert the four L-shaped reinforcing strips 4 into the lower insertion slot 10, then insert the mating slot 12 of the reinforcing ring 11 into the top of the side panel 2, and insert the top of the four L-shaped reinforcing strips 4 into the upper insertion slot 13. The goods are then stacked onto the side panel 2, and finally the top of the reinforcing ring 11 is sealed with the cover plate 3. The reinforcing ring 11 makes the top of the side panel 2 less prone to deformation, allowing the workers to place the goods into the side panel 2, especially the goods whose size is not much different from the opening size of the top of the side panel 2, thus improving the placement efficiency. The L-shaped reinforcing strips 4 and the reinforcing ring 11 enhance the impact resistance of the side panel 2, and the L-shaped reinforcing strips 4 also enhance the vertical compression resistance of the side panel 2, allowing for the stacking of more layers of cardboard boxes.

[0029] Workers use a strapping machine to wrap the strapping tape around the base plate 1, side guards 2, and cover plate 3. The strapping tape is then inserted into the bundling slot 9. When the moving mechanism of forklifts and other equipment is inserted into the handling slot 8, it will not touch the strapping tape, effectively preventing damage to the strapping tape during transportation.

[0030] Workers use forklifts or other tools to move the cartons through the handling slots 8, increasing the speed of cargo transfer and stacking. When stacking, the upper limit hole 7 is inserted into the lower limit post 6, making the weight of the cartons more uniform, neat and stable, and the bottom cartons are subjected to more uniform force, reducing the possibility of the side guards 2 bending or deforming under force.

[0031] When the goods are heavy, the staff use a restraint strap to wrap around the perimeter of the limiting groove block 5, and use Velcro or a tightening device to tighten the restraint strap, so that the L-shaped reinforcing strip 4 is not easy to bend or deform outward, further improving the vertical compression resistance of the carton.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
