[0033] 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.

[0034] Reference Figures 1-6This utility model provides an embodiment of a reinforced corrugated cardboard box, comprising a box body 1 for containing and protecting internal goods. The box body 1 is made of corrugated cardboard. Main box covers 2 are fixedly connected to the top and bottom front and rear sides of the box body 1. The main box covers 2 can seal the front and rear of the box body 1 during packaging, providing dust and impact protection, and also providing a stable force-bearing surface during stacking. Secondary box covers 3 are fixedly connected to the top and bottom left and right sides of the box body 1. The main box covers 2 and secondary box covers 3 can seal the top and bottom of the box body 1 during packaging, providing dust and impact protection, and also providing a stable force-bearing surface during stacking. A shock-absorbing component is installed inside the box body 1. The shock-absorbing component includes a cushioning pad 4 made of rubber, which abuts against the inner wall of the box body 1. The cushioning pad 4 fits tightly against the inner wall of the box body 1, reducing vibration. The impact on the goods is directly caused by the following: the bottom of the cushioning pad 4 is fixedly connected to the pad plate 5, and the bottom of the pad plate 5 is fixedly connected to multiple evenly distributed springs 6. The pad plate 5 bears the pressure transmitted by the cushioning pad 4 on the one hand, and provides a stable support surface for the springs 6 below on the other hand, ensuring that the springs 6 are evenly stressed. The springs 6 use their own elastic deformation to perform secondary buffering of the impact force, converting the vibration energy into the elastic potential energy of the springs 6, effectively reducing the vibration amplitude. The bottom of the springs 6 is fixedly connected to the front and rear distributed support plates 7. The support plates 7 prevent the springs 6 from shifting when stressed. The bottom of the support plates 7 is fixedly connected to the connecting plate 8, which plays a role in stabilizing the connection. The bottom of the connecting plate 8 is fixedly connected to the support frame 9. The support frame 9 is the bottom support structure of the shock absorption component, which distributes the force transmitted from above to the bottom of the box 1, while enhancing the pressure resistance of the bottom of the box 1 and preventing the bottom from deforming.

[0035] Reference Figures 1-3 A cardboard sleeve 10 is fitted around the outer periphery of the box body 1. The cardboard sleeve 10 covers the outside of the box body 1 and provides additional protection for the box body 1. At the same time, it provides auxiliary positioning and fixing functions when stacking. Multiple evenly distributed limiting rods 11 are fixedly connected to the outside of the box body 1. The limiting rods 11 are slidably connected in the limiting grooves 12. The limiting grooves 12 are slidably connected to the limiting rods 11 on the box body 1. When the cardboard boxes are stacked, the cardboard sleeve 10 slides into the outside of the lower cardboard box. At the same time, the limiting rods 11 limit the descent depth of the cardboard sleeve 10, so that the upper and lower cardboard boxes are stacked together stably and quickly. Positioning plates 14 are fixedly connected to the front and left sides of the cardboard sleeve 10. Positioning grooves 13 are opened on the rear and right sides of the cardboard sleeve 10. Multiple evenly distributed limiting grooves 12 are opened on the outside of the cardboard sleeve 10. The positioning plates 14 are slidably connected in the positioning grooves 13. The positioning plates 14 and the positioning grooves 13 can quickly and smoothly merge the left and right cardboard boxes together, which is convenient for workers to stack multiple cardboard boxes and ensure that the stacking is stable, firm and flat.

[0036] Reference Figure 4The pad 5 abuts against the inner wall of the housing 1. This abutting method prevents the pad 5 from shifting when under force, thereby ensuring the normal operation of the shock absorption component. The front and rear parts of the connecting plate 8 abut against the inner wall of the housing 1. The connection between the connecting plate 8 and the inner wall of the housing 1 further enhances the connection stability between the shock absorption component and the housing 1. The bottom left and right sides of the support plate 7 abut against the top of the bottom auxiliary housing cover 3. The front and rear sections of the support frame 9 abut against the inner wall of the housing 1. The top of the support frame 9 abuts against the bottom of the bottom auxiliary housing cover 3. The bottom of the support frame 9 abuts against the top of the bottom main housing cover 2. In this way, the entire shock absorption component can be distributed to the bottom of the housing 1 through the auxiliary housing cover 3, while improving the stability of the overall structure.

[0037] Working principle: When the reinforced corrugated cardboard box encounters vibration during transportation, the rubber buffer pad 4, which is pressed against the inner wall of the box body 1, uses its own elasticity to flexibly buffer the initial impact force. Then, the impact force is transmitted through the pad plate 5 to multiple evenly distributed springs 6. The springs 6 generate elastic deformation through compression or stretching, further absorbing and dispersing the vibration energy. After the support plate 7 receives the force transmitted by the springs 6, it is evenly transmitted to the support frame 9 through the connecting plate 8, and finally dispersed to the main box cover 2 and the secondary box cover 3 at the bottom of the box body 1. This multi-stage buffering process weakens the vibration force layer by layer, thereby effectively protecting fragile items such as electronic products and glass products inside the box and reducing the risk of breakage.

[0038] When stacking cartons, the operator aligns the upper cartons with the lower cartons. The upper carton sleeve 10 falls under gravity. At the same time, the limiting rod 11 on the outside of the carton 1 slides vertically along the limiting groove 12 on the outside of the carton sleeve 10. The length of the limiting groove 12 limits the descent depth of the carton sleeve 10, achieving automatic horizontal alignment and fixation, and preventing the cartons from shifting left or right. When it is necessary to stack cartons left and right, the operator brings the side of one carton close to another. At this time, the positioning plate 14 on the front or left side of the carton sleeve 10 can quickly align with the positioning groove 13 on the rear or right side of the adjacent carton sleeve 10. Through lateral translation, the positioning plate 14 slides into the positioning groove 13, forming a stable interlocking structure, thereby quickly and smoothly connecting the two cartons together. This design not only greatly improves the efficiency of carton stacking, but also significantly enhances the overall stability after stacking through tight nesting, effectively preventing cartons from shifting or tipping over during storage and transportation, and ensuring the safety of goods.

[0039] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
