Description

Technical Field

[0001] This utility model relates to the field of logistics packaging equipment technology, and more specifically, to a foldable heavy-duty packaging box. Background Technology

[0002] Heavy-duty packaging boxes are protective containers specifically designed for transporting large, heavy, or high-value industrial equipment. Their design must comply with international transportation standards and possess impact resistance, rust prevention, and stacking pressure resistance. Some customized packaging boxes integrate temperature and humidity monitoring, GPS tracking, and hydraulic cushioning systems to ensure the safe transportation of precision equipment in complex environments. Heavy-duty packaging boxes achieve reusability through modular design, reducing logistics costs and are suitable for cross-border logistics transportation in fields such as machinery, military, and aerospace.

[0003] A search revealed that the heavy-duty packaging box with publication number CN201432841Y addresses the problem that cardboard boxes have limited load-bearing capacity and are easily damaged during transportation, thus causing damage to the transported goods. The paper solves this problem by using cardboard boxes and pallets.

[0004] However, among the aforementioned technologies, there is a problem that heavy packaging boxes cannot be folded. This causes heavy packaging boxes to occupy a lot of warehouse space when they are not in use, increasing the warehousing costs of logistics and transportation. Therefore, improvements are needed.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1 to 6 As shown, this utility model provides a foldable heavy-duty packaging box, including a base plate 1. Pads 2 are fixedly connected to both the front and rear ends of the upper surface of the base plate 1. A first baffle 3 is fixedly connected to both the left and right ends of the pads 2. The lower surface of the first baffle 3 is fixedly connected to the upper surface of the base plate 1. A first rotating shaft 4 is movably connected to both the left and right sides of the inner surface of the pads 2. Both the front and rear ends of the first rotating shaft 4 penetrate the pads 2 and extend into the interior of the pads 2. Two first box plates 5 are fixedly sleeved on the outer surface of the first rotating shaft 4. The outer surfaces of both the front and rear sides of the two first box plates 5 are movably connected to the inner surface of the pads 2. The front and rear sides of the inner surface of the first baffle 3 are... A movable groove 6 is provided, and a second rotating shaft 7 is movably connected to the inner surface of the movable groove 6. A second box plate 8 is fixedly sleeved on the outer surface of the second rotating shaft 7. There are two second box plates 8. The outer surfaces of the left and right sides of the two second box plates 8 are movably connected to the inner surface of the first baffle 3. The design of the first rotating shaft 4 and the first box plate 5 allows the two first box plates 5 to rotate around the first rotating shaft 4 as the axis, thereby realizing the folding of the two first box plates 5. The design of the movable groove 6 allows the second rotating shaft 7 and the second box plate 8 to move upward along the inner surface of the movable groove 6, thereby allowing the two second box plates 8 to be stacked on top of the two first box plates 5 as a whole.

[0018] The lower surface of the base plate 1 is fixedly connected with four strip blocks 9, which are made of wood. The design of the strip blocks 9 not only provides support for the base plate 1 as a whole, but also prevents the base plate 1 from directly contacting the ground, thereby avoiding water from the ground from getting on the lower surface of the base plate 1.

[0019] Among them, the outer surfaces of the two second-tier box panels 8 are movably connected with box covers 10, and the inner surface of the box covers 10 is movably connected with the outer surfaces of the two first-tier box panels 5. The design of the box covers 10 serves to seal and shield the inner surfaces between the two second-tier box panels 8 and the two first-tier box panels 5, thereby achieving the function of protecting the goods.

[0020] The upper surfaces of both the first box panel 5 and the second box panel 8 are movably connected with insert plates 11. The bottom end of the insert plate 11 passes through the first box panel 5 and the second box panel 8 and extends into the interior of the first box panel 5 and the second box panel 8. The design of the insert plate 11 serves to fix the position of the first box panel 5 and the second box panel 8. When the insert plate 11 is pulled out of the first box panel 5 and the second box panel 8, the operator can fold and store the first box panel 5 and the second box panel 8.

[0021] Among them, the outer surfaces of the two No. 2 box panels 8 are movably connected with No. 2 baffles 14. The bottom end of the No. 2 baffle 14 is fixedly connected to the upper surface of the bottom plate 1, and the outer surfaces of the left and right ends of the No. 2 baffle 14 are fixedly connected to the No. 1 baffle 3. The design of the No. 2 baffle 14 serves to block the gap between the No. 2 box panel 8 and the bottom plate 1. When the No. 2 box panel 8 and the No. 2 baffle 14 are in contact, the sand and soil from the outside cannot enter between the No. 1 box panel 5 and the No. 2 box panel 8.

[0022] The inner surface of the insert plate 11 is movably fitted with an insert post 12. The outer end of the insert post 12 passes through the insert plate 11 and the first box plate 5 in sequence and extends to the outer side of the first box plate 5 and is fixedly connected to a connecting plate 13. When the outer surface of the insert post 12 and the first box plate 5 are movably connected to the inner surface of the insert plate 11, the insert plate 11 will be fixed inside the first box plate 5 and the second box plate 8, thereby preventing the insert plate 11 from falling off from the inner surface of the first box plate 5 and the second box plate 8.

[0023] Hollow blocks 16 are movably connected to the outer surface of the connecting plate 13. There are four hollow blocks 16. The outer surfaces of the four hollow blocks 16 are fixedly connected to the outer surfaces of the two first box plates 5 respectively. Springs 15 located inside the hollow blocks 16 are fixedly connected to the outer surface of the connecting plate 13. The other end of the springs 15 is fixedly connected to the outer surface of the first box plate 5. The design of the springs 15 allows the connecting plate 13 to move automatically toward the hollow blocks 16 under the elastic force of the springs 15. The design of the hollow blocks 16 serves to shield the springs 15.

[0024] Working principle and usage process of this utility model: First, the operator pulls the connecting plate 13, causing the insert 12 to move to the outside of the first box plate 5 and pull out the insert plate 11. At this time, the limit of the insert plate 11 on the first box plate 5 and the second box plate 8 will be released. Then, the operator pulls the connecting plate 13 again, causing the insert 12 to be reinserted into the first box plate 5. Then, the operator places the insert plate 11 on the upper surface of the bottom plate 1 and rotates the first box plate 5.

[0025] At this point, the two No. 1 box panels 5 will rotate towards each other, eventually contacting and pressing down on the insert plate 11. Then, the operator will lift any one of the No. 2 box panels 8 upwards, moving it above the connecting plate 13. The operator will then rotate this No. 2 box panel 8, pressing it down on the connecting plate 13. The operator will then lift and rotate the other No. 2 box panel 8, finally stacking the two No. 2 box panels 8 together, thus completing the overall folding and storage of the base plate 1.
