Description

Technical Field

[0001] This utility model relates to the field of cardboard box technology, and in particular to a cardboard box with a pressure-resistant structure. Background Technology

[0002] Cardboard boxes are a widely used packaging container. They are mainly used to package various products, such as daily necessities, electronic devices, and food, protecting them from damage during transportation and storage. Cardboard boxes are typically hexagonal in structure, with top and bottom surfaces and four sides. They are easy to print with various patterns and text, and can be used for product branding, instructions, etc.

[0003] Traditional cardboard boxes are generally rectangular in shape with a regular structure. Their main components are the lid, bottom, and side panels, primarily made of corrugated cardboard. Corrugated cardboard is a multi-layered cardboard with a corrugated core and linerboard on the top and bottom. The corrugated core resembles a series of continuous arches, which can cushion external forces to some extent. However, the inherent material properties of corrugated cardboard limit its compressive strength. From a materials mechanics perspective, its compressive strength is affected by factors such as the corrugation shape, cardboard thickness, and material quality. In practical applications, when the box is subjected to significant pressure, such as when stacking multiple boxes or being squeezed by heavy objects during transport, the box is prone to deformation. If the box contains fragile items, this deformation can lead to product damage. To address these issues, we have proposed this cardboard box with a compression-resistant structure.

[0020] 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.

[0021] like Figure 1-4As shown, a cardboard box with a pressure-resistant structure includes a cardboard box body 1, a top frame 5, multiple first connectors 3 and multiple second connectors 11. The cardboard box body 1 is provided with a bottom frame 2. Multiple insertion holes 8 are provided on the side walls of both the bottom frame 2 and the top frame 5. A connecting mechanism for connecting each other is provided in the bottom frame 2 and the top frame 5. The connecting mechanism includes a rod 9 disposed in the insertion hole 8. A vertical rod 7 is fixedly connected to the side walls of two adjacent rods 9 in the vertical direction.

[0022] The bottom frame 2 is provided with a support mechanism for supporting goods. The support mechanism includes multiple third connectors 12 that are fixedly connected to the inner wall of the bottom frame 2. The multiple third connectors 12 are arranged at equal intervals.

[0023] In this utility model, the vertical rod 7 is slidably connected to the adjacent second connecting member 11. The cross-section of the second connecting member 11 is X-shaped. The second connecting member 11 is slidably connected to the vertical rod 7. The X-shaped structure increases the contact area with the vertical rod 7. When the carton is compressed, it can better withstand the force from different directions and prevent the vertical rod 7 from shaking or displacing.

[0024] In this utility model, a placement block 10 is fixedly connected to the side wall of the vertical rod 7, and the third connecting member 12 has an X-shaped cross section. The third connecting member 12 is fixed to the inner wall of the bottom frame 2 to support the goods. The X-shaped design increases the contact area with the goods, which can more evenly distribute the weight of the goods and improve the stability of the support.

[0025] In this utility model, slots 6 are provided on the side walls of both the bottom frame 2 and the top frame 5. Inserts 4 are provided in the slots 6. The inserts 4 are fixedly connected to the adjacent first connecting member 3. The gap between the bottom frame 2 and the top frame 5 is protected by the first connecting member 3, reducing the impact of lateral pressure on the carton structure.

[0026] In this utility model, the first connecting member 3 has an X-shaped cross section. Its X-shaped structure cooperates with the slot 6 and the insert 4. When the carton is subjected to external force, it can distribute the force to multiple contact parts, preventing the insert 4 from easily coming out of the slot 6, making the connection between the top frame 5 and the bottom frame 2 more stable. The slot 6 is slidably connected to the adjacent insert 4, and the insert rod 9 is slidably connected to the adjacent insertion hole 8.

[0027] In the initial state, the bottom frame 2, vertical rod 7, top frame 5, first connector 3, and second connector 11 are separated from each other, and the carton body 1 is folded.

[0028] It should be noted that this utility model is a cardboard box with a pressure-resistant structure. The user unfolds the cardboard box body 1, first places the bottom frame 2 at the bottom of the box, then inserts the inserts 9 of the multiple vertical rods 7 into the insertion holes 8, inserts the inserts 4 of the first connector 3 into the slots 6, and then places the top frame 5 on the inserts 9 and inserts 4 on the vertical rods 7 and the first connector 3 to complete the assembly of the cardboard box. Then, the goods or items are placed in, the cover plate of the cardboard box body 1 is closed, and the cover plate is sealed with tape. The bottom frame 2, vertical rods 7, top frame 5, first connector 3, and second connector 11 serve as the main frame inside the cardboard box body 1, which can greatly improve the pressure resistance of the cardboard box body 1.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
