Description

Technical Field

[0001] This utility model relates to the field of rotomolded packaging boxes, and in particular to a corner reinforcement structure for an impact-resistant rotomolded packaging box. Background Technology

[0002] Rotomolded packaging boxes are widely used in the transportation and storage of heavy equipment, precision instruments, and fragile goods due to their advantages such as integral molding, good sealing, and corrosion resistance. These boxes are typically made of special rotomolding materials such as polyethylene, possessing excellent overall structural strength and weather resistance, making them suitable for various industrial environments.

[0003] However, existing ordinary rotomolded packaging boxes still have significant shortcomings in dealing with impact conditions such as corner collisions and drops during actual transportation, loading, unloading, and stacking. On the one hand, the corner areas of the box lack specialized energy absorption structures, causing the impact force to be directly transmitted to the inside of the box, which can easily cause structural damage. On the other hand, the box lacks an effective multi-dimensional elastic support system, making it difficult to effectively suppress the displacement of items during vibration or drops, resulting in damage to the internal items due to collisions. The overall protective performance needs to be further improved. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a corner reinforcement structure for an impact-resistant rotomolded packaging box. This structure prevents structural displacement or failure, significantly enhances the box's impact resistance under conditions such as drops and collisions, absorbs vibration energy, and prevents damage to items due to internal collisions. It is particularly suitable for the transportation of fragile or precision equipment.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A corner reinforcement structure for an impact-resistant rotomolded packaging box includes a rotomolded placement box for support, a rotomolded cover frame rotatably connected to the top of the placement box, and multiple reinforcing rods evenly fixed to the top of the cover frame. Installation notches are provided around both the placement box and the cover frame, and corner buffer components are installed inside each notch to protect the corners of the placement box. An upper connecting frame is fixedly connected to the upper inner side of the cover frame, and an upper elastic protective net is fixedly connected inside the upper connecting frame. A lower connecting frame is fixedly connected to the upper inner side of the placement box, and a buffer placement component is installed inside the lower connecting frame to ensure stability during transport.

[0006] Furthermore, the buffer placement assembly includes a placement frame fixed at the bottom of the lower connecting frame. Multiple longitudinal slots are provided on both the front and rear sides of the placement frame, and transverse slots are provided on both sides of the placement frame. A longitudinal elastic protective net is fixedly connected inside each of the longitudinal slots, and a transverse elastic protective net is fixedly connected inside each of the transverse slots.

[0007] Furthermore, the corner buffer assembly includes a connecting block fixed inside the mounting notch, with multiple filling grooves evenly provided on the outer side of the connecting block, and a through-fixing rod fixedly connected inside the connecting block.

[0008] Furthermore, the corner buffer assembly also includes a side rubber pad fixed inside the mounting notch. The inside of the side rubber pad is filled inside the filling groove, and a through fixing rod passes through the inside of the side rubber pad. Anti-detachment plates are fixedly connected to both the upper and lower sides of the through fixing rod.

[0009] Furthermore, multiple limiting straps are fixedly connected to both the inner and outer sides of the mounting notch, with the inner side of the limiting straps adhering to the outer side of the side pad.

[0010] Furthermore, multiple lifting handles are rotatably connected to both sides of the rotational molding placement box.

[0011] Furthermore, a protective rubber pad is fixedly connected to the inner side of the placement frame.

[0012] This utility model has the following beneficial effects: 1. In this utility model, when the corner of the packaging box is subjected to external impact, the impact force is effectively guided to the corner buffer component through the installation notch. The side rubber pad undergoes elastic deformation in the filling groove, absorbing and dispersing the impact energy. Combined with the limiting effect of the through fixing rod and the anti-detachment plate, it prevents structural displacement or failure, and significantly enhances the impact resistance of the box under conditions such as drop and collision.

[0013] 2. In this utility model, the placement frame inside the box is fixed by the lower connecting frame. The longitudinal groove and the transverse groove are respectively installed with longitudinal elastic protective net and transverse elastic protective net, forming a multi-dimensional elastic support system. This system can effectively suppress the displacement of the items and absorb vibration energy during vibration or drop, and avoid damage to the items due to internal collision. It is especially suitable for the transportation of fragile or precision equipment. Attached Figure Description

[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] Reference Figures 1-3 This utility model provides an embodiment of a corner reinforcement structure for an impact-resistant rotomolded packaging box, comprising a rotomolded placement box 1 for support, a rotomolded cover frame 2 rotatably connected to the top of the rotomolded placement box 1, a plurality of reinforcing rods 3 uniformly fixedly connected to the top of the rotomolded cover frame 2, mounting notches 8 being provided around the rotomolded placement box 1 and the rotomolded cover frame 2, and corner buffer components installed inside the mounting notches 8 to protect the corners of the rotomolded placement box 1, an upper connecting frame 6 fixedly connected to the upper inside of the rotomolded cover frame 2, an upper elastic protective net 7 fixedly connected inside the upper connecting frame 6, and a lower connecting frame 15 fixedly connected to the upper inside of the rotomolded placement box 1, with a buffer placement component installed inside the lower connecting frame 15 to protect the corners of the rotomolded placement box 1. To ensure the stability of goods transportation, the corner buffer assembly includes a connecting block 10 fixed inside the mounting notch 8. Multiple filling grooves 11 are evenly provided on the outer side of the connecting block 10. A through-fixing rod 12 is fixedly connected inside the connecting block 10. The corner buffer assembly also includes a side rubber pad 4 fixed inside the mounting notch 8. The inner side of the side rubber pad 4 is filled inside the filling groove 11. The through-fixing rod 12 passes through the inside of the side rubber pad 4. Anti-detachment plates 13 are fixedly connected to both the upper and lower sides of the through-fixing rod 12. Multiple limiting straps 9 are fixedly connected to both the inner and outer sides of the mounting notch 8. The inner side of the limiting straps 9 is attached to the outer side of the side rubber pad 4. Multiple lifting handles 5 are rotatably connected to both sides of the rotomolded placement box 1. When the corners of the packaging box are subjected to external impact during transportation or handling, the main body consisting of the rotomolded placement box 1 and the rotomolded cover frame 2 effectively transmits the impact force to the corner buffer assembly through the installation notches 8 set around the perimeter. The side rubber pads 4 in this assembly are embedded in the filling grooves 11 of the connecting block 10 and undergo elastic deformation when squeezed, thereby absorbing and dispersing the impact energy; the through fixing rod 12 passes through the connecting block 10 and the side rubber pads 4, and is limited by the anti-detachment plates 13 at the upper and lower ends, effectively preventing the rubber pads from shifting or loosening under repeated impacts, and ensuring the stability and durability of the buffer structure in long-term use.

[0018] Reference Figure 4 and Figure 5 The buffer placement assembly includes a placement frame 14 fixed at the bottom of the lower connecting frame 15. Multiple longitudinal grooves 19 are provided on both the front and rear sides of the placement frame 14. Transverse grooves 20 are provided on both sides of the placement frame 14. A longitudinal elastic protective net 18 is fixedly connected inside the longitudinal grooves 19. A transverse elastic protective net 17 is fixedly connected inside the transverse grooves 20. A protective rubber pad 16 is fixedly connected to the inner side of the placement frame 14. Inside the container, the placement frame 14 is fixed to the bottom of the container via a lower connecting frame 15. Longitudinal grooves 19 and transverse grooves 20 are respectively provided on its front and rear sides, and longitudinal and transverse elastic protective nets 18 and 17 are installed accordingly, forming a complete mesh-like elastic support system. When the container vibrates or falls during transportation, this elastic protective net system can effectively restrict the movement of the internal items and absorb some of the impact and vibration energy through its own elastic deformation, thereby preventing damage to the items due to collision.

[0019] Working Principle: When the corners of the packaging box are impacted during transportation or handling, the main body consisting of the rotomolded placement box 1 and the rotomolded cover frame 2 directs the impact force to the corner buffer assembly through the installation notches 8 on all four sides. The side rubber pads 4 in this assembly are filled in the filling grooves 11 of the connecting block 10. When compressed, they undergo elastic deformation, absorbing and dispersing the impact energy. The through-fixing rod 12 passes through the connecting block 10 and the side rubber pads 4, and is limited by the anti-detachment plates 13 at the upper and lower ends to prevent the rubber pads from shifting or falling off under repeated impacts, ensuring the stability and durability of the buffer structure. Inside the box, the placement frame 14 is fixed to the bottom of the box through the lower connecting frame 15. The longitudinal grooves 19 and transverse grooves 20 on its front and rear sides are respectively equipped with longitudinal elastic protective nets 18 and transverse elastic protective nets 17, forming a mesh elastic support system. When the box vibrates or falls, this elastic protective net system can effectively suppress the displacement of the internal items and absorb vibration energy through its own deformation, preventing the items from being damaged by collision.

[0020] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
