Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figure 1-6 , the present utility model provides the following technical solutions: A foam packaging box capable of enhancing compressive performance, including a foam packaging box body 1 and a foam box cover 2 connected to the top of the foam packaging box body 1. A first reinforcement plate 3 is connected to the inner wall corner of the foam packaging box body 1;

[0024] One side of the first reinforcement plate 3 is connected to a movable plate 4. A second reinforcement plate 5 is also connected to the inner wall corner of the foam packaging box body 1. One side of the second reinforcement plate 5 is connected to a positioning plate 6. The other end of the positioning plate 6 is connected to a limit block 7. One side of the limit block 7 is movably connected to a movable rod 8. The other end of the movable rod 8 is connected to a linkage plate 9. One side of the linkage plate 9 is connected to a linkage spring 10. The other side of the linkage plate 9 is connected to a clamping post 11.

[0025] Preferably: The first reinforcement plate 3, the movable plate 4, the second reinforcement plate 5 and the positioning plate 6 are all made of PVC material, and the surface size of the movable plate 4 is adapted to the inner wall opening size of the limit block 7. By adopting the method of reuse, material waste can be avoided.

[0026] Preferably: The other end of the linkage spring 10 is connected to the inner wall of the limit block 7, and the linkage spring 10 and the linkage plate 9 form an elastic telescopic structure.

[0027] Preferably: A positioning groove is provided on one side of the movable plate 4, and the clamping post 11 and the positioning groove form an engaging structure. By fitting the clamping post 11 into the positioning groove, it is convenient to fix the movable plate 4.

[0028] Preferably, a handle 12 is connected to the bottom openings on both sides of the foam packaging box body 1, and the handle 12 is made of plastic. By using the handle 12, it is convenient for personnel to carry the foam box and avoid damaging the foam box during handling.

[0029] Preferably, an L-shaped clamping strip 13 is connected to the surface of the handle 12, and a clamping groove 14 is formed in the bottom surface of the foam packaging box body 1. The clamping strip 13 is engaged with the clamping groove 14. By installing the clamping strip 13 into the inside of the clamping groove 14, it is convenient to assemble the handle 12.

[0030] The working principle of the specific use of the present utility model: First, by pulling the movable rod 8, the linkage plate 9 is driven to squeeze the linkage spring 10, so that the clamping column 11 is disengaged from the connection with the movable plate 4. Then, the first reinforcing plate 3 and the second reinforcing plate 5 are adjusted outward or inward relative to each other to facilitate adaptation to the foam packaging box body 1. At the same time, the movable plate 4 slides along the opening on one side of the limiting block 7. When the distance between the first reinforcing plate 3 and the second reinforcing plate 5 is adjusted, the movable rod 8 is released. At this time, the clamping column 11 is subjected to the elastic force of the rebound of the linkage spring 10, and the clamping column 11 is clamped into the positioning groove, thereby improving the overall bearing capacity of the foam packaging box body 1 and extending the service life of the foam packaging box body 1. In addition, the reinforcing plate can be reused and can be adapted and adjusted according to the size of the foam box, improving the practicability and enhancing the compressive performance of the foam box. In addition, by clamping the handle 12 into the bottom opening of the foam packaging box body 1, the clamping strip 13 on the surface of the handle 12 is docked with the clamping groove 14. Then, personnel can carry the foam packaging box body 1 through the handle 12 to avoid damaging the foam packaging box body 1.
