Detailed Implementation

[0022] 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.

[0023] Please see Figures 1-3 This utility model provides a high-strength packaging box, including a matching lower wooden box 1 and an upper box cover 11. The bottom of the lower wooden box 1 and the top of the upper box cover 11 are respectively provided with a lower iron frame 5 and an upper iron frame 9. Matching lower angle irons 4 and upper angle irons 8 are welded to the four corners of the lower iron frame 5 and the upper iron frame 9. The lower angle irons 4 and the upper angle irons 8 are quickly installed together by a connecting component. The lower wooden box 1 and the upper box cover 11 are provided with side protection components 6 on all four sides. The bottom of the lower iron frame 5 is fixedly connected with three evenly distributed wooden frames 2. Two fork slots 3 are provided between the wooden frames 2 and the lower iron frame 5, so that forklifts can lift and move the lower wooden box 1 from the two fork slots 3 or from the fork holes formed between two adjacent wooden frames 2.

[0024] In this utility model, the connecting component is a connecting angle iron 7. Both sides of the connecting angle iron 7 have mounting holes that mate with the lower angle iron 4 and the upper angle iron 8. The upper angle iron 8 extends downwards to near the middle of the lower wooden box 1. After the lower wooden box 1 and the upper box cover 11 are closed, the four opposing lower angle irons 4 and upper angle irons 8 are paired with each other. Then, the lower angle irons 4 and upper angle irons 8 are connected and fixed by the connecting angle iron 7. Alternatively, a self-tapping screw can be directly passed through the connecting angle iron 7, the lower angle irons 4, and the upper angle iron 8 and screwed into the lower wooden box 1 to achieve connection and fixation. Therefore, the lower wooden box 1 and the upper box... The corners of the cover 11 are protected by a strong protective frame formed by the lower iron frame 5, the upper iron frame 9, the four lower corner irons 4 and the upper corner iron 8. Since the upper corner iron 8 extends downward to near the middle of the lower wooden box 1, the contact surface between the upper corner iron 8 and the lower wooden box 1 is increased. The connection and fixing position of the lower corner irons 4 and the upper corner iron 8 is moved down from the four corners of the upper box cover 11 to the corners of the lower wooden box 1, so as to achieve the misalignment between the connection position of the lower corner irons 4 and the upper corner iron 8 and the connection position of the lower wooden box 1 and the upper box cover 11, which further improves the connection stability of the upper box cover 11 and the lower wooden box 1 after they are closed.

[0025] In this utility model, multiple weight-reducing grooves 10 are provided on both sides of the lower iron frame 5, the upper iron frame 9, the lower angle iron 4, and the upper angle iron 8. By removing material from non-critical stress areas, the material is concentrated in high stress areas to achieve "equal strength design". Therefore, not only is the weight reduced, but resources are also saved.

[0026] In this utility model, the side protection component 6 includes a lower iron plate 603 welded between two adjacent lower angle irons 4. The upper iron frame 9 has upper iron plates 601 welded to all four sides to mate with the lower iron plate 603. The ends of the upper iron plates 601 are provided with connecting components two that quickly connect to the lower iron plate 603. The connecting components two include two connectors 602 welded to the bottom of the upper iron plate 601. The connectors 602 are staggered with the upper iron plate 601, forming a clearance groove 604 to avoid obstructing the lower iron plate 603. The connector 602 has a connecting hole 605 inside for fixing to the lower iron plate 603. The connector 602 is snapped onto the outside of the lower iron plate 603, and then a self-tapping screw is passed directly through the connecting hole 605 and the lower iron plate 603 and screwed into the lower wooden box 1. This enables the quick installation and fixing of the upper iron plate 601 and the lower iron plate 603. The side protection assembly 6 formed by the upper iron plate 601 and the lower iron plate 603 can provide four-sided protection for the lower wooden box 1, further improving the protective capability of the packaging box.

[0027] The working principle of this utility model is as follows: In use, first, the object is placed into the lower wooden box 1 and secured. This can be done using straps, screws, or other methods. Then, the upper box cover 11 is snapped onto the lower wooden box 1. After the lower wooden box 1 and the upper box cover 11 are closed, the four lower angle irons 4 and upper angle irons 8 are paired with each other. Then, the lower angle irons 4 and upper angle irons 8 are connected and secured using connecting angle irons 7. Alternatively, self-tapping screws can be directly passed through the connecting angle irons 7, lower angle irons 4, and upper angle irons 8 and screwed into the lower wooden box 1 to achieve a secure connection. Therefore, the corners of the lower wooden box 1 and the upper box cover 11 are highly protected by the protective frame formed by the lower iron frame 5, the upper iron frame 9, the four lower angle irons 4, and the upper angle irons 8. Furthermore, because the upper angle irons 8 extend downwards to near the middle of the lower wooden box 1... Therefore, the contact area between the upper angle iron 8 and the lower wooden box 1 is increased, and the connection and fixing position of the lower angle iron 4 and the upper angle iron 8 is moved from the four corners of the upper box cover 11 to the corners of the lower wooden box 1, realizing the misalignment between the connection position of the lower angle iron 4 and the upper angle iron 8 and the connection position of the lower wooden box 1 and the upper box cover 11, further improving the connection stability after the upper box cover 11 and the lower wooden box 1 are closed. At the same time, the connector 602 is clamped on the outside of the lower iron plate 603, and then passes directly through the connection hole 605 and the lower iron plate 603 through the self-tapping screw and is rotated and screwed into the lower wooden box 1, thereby realizing the quick installation and fixing of the upper iron plate 601 and the lower iron plate 603, and the side protection component 6 formed by the upper iron plate 601 and the lower iron plate 603 can complete the four-sided protection of the lower wooden box 1, further improving the protection capability of the packaging box.

[0028] The electronic components and modules used in this utility model can all be parts that are commonly used in the market and can achieve the specific functions in this case. The specific models and sizes can be selected and adjusted according to actual needs.
