[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0026] Reference Figures 1 to 5 A cargo protection device for road freight transport includes a load-bearing component 1, which includes a storage plate 13; wherein the load-bearing component 1 is the entire device consisting of a placement platform and a support platform, and the upper surface of the storage plate 13 has a certain space for placing cargo.

[0027] The buffer assembly 2 includes a first threaded rod 25 and a second threaded rod 26 disposed on the outer wall of the storage plate 13, and a protective plate 29 disposed on the outside of the first threaded rod 25 and the second threaded rod 26. The outer walls of the first threaded rod 25 and the second threaded rod 26 are provided with threads of opposite directions. The first threaded rod 25 and the second threaded rod 26 are installed perpendicular to each other, and their surfaces are provided with thread grooves of opposite directions on both sides. The reverse-designed thread grooves on both sides drive the collar 27 on its surface to move towards each other or in the opposite direction.

[0028] The first threaded rod 25 and the second threaded rod 26 are rotated, thereby using the opposite threads on their outer surfaces to move the protective plates 29 away from or towards each other, thus achieving clamping and buffering of goods of different sizes.

[0029] Specifically, the supporting component 1 also includes a support plate 11 fixedly connected to the outer wall of the storage plate 13. Self-locking wheels 12 are fixedly installed at the four corners of the support plate 11. The support plate 11 supports the storage plate 13 and the buffer component 2, and, together with the self-locking wheels 12 at its bottom, enables rapid entry and exit from the truck bed, improving loading and unloading efficiency. The self-locking wheels 12 ensure the stability of the support plate 11 within the truck bed during transportation, preventing it from moving arbitrarily.

[0030] Furthermore, the buffer assembly 2 also includes a first through groove 21 and a second through groove 22 formed on the outer wall of the storage plate 13, with a certain height difference between the first through groove 21 and the second through groove 22. Since both the first threaded rod 25 and the second threaded rod 26 need to rotate, they need to be installed in a staggered manner inside the storage plate 13, resulting in a certain height difference between them.

[0031] Reference Figure 3 , Figure 4 and Figure 5 The first threaded rod 25 is disposed on the inner wall of the first through groove 21, and the second threaded rod 26 is disposed on the inner wall of the second through groove 22. Multiple sets of sliding grooves 23 are formed on the end face of the storage plate 13. The first through groove 21 and the second through groove 22 are located at both ends of the storage plate 13, with a portion of the middle position left unconnected, thereby limiting the first threaded rod 25 and the second threaded rod 26.

[0032] Specifically, multiple sets of sliding grooves 23 are respectively connected to the first through groove 21 or the second through groove 22, and the end face of the storage plate 13 is provided with a guide groove 24. Among them, there are four sets of sliding grooves 23, which are located around the upper end face of the storage plate 13, and the sliding grooves 23 have a certain length to ensure that the two threaded rods can move a sufficient distance to accommodate goods of different sizes.

[0033] Furthermore, both the first threaded rod 25 and the second threaded rod 26 are threadedly connected to a collar 27, and a connecting plate 28 is fixedly connected to the end face of the collar 27. The connecting plate 28 can move along the slide groove 23. The collar 27 can move along the surfaces of the first threaded rod 25 and the second threaded rod 26 by rotating the threaded rod, thereby matching the size of the goods.

[0034] Reference Figure 4 and Figure 5 The outer wall of the protective plate 29 is fixedly connected to the end face of the connecting plate 28. The outer wall of the protective plate 29 is integrally formed with a guide plate 210, which is adapted to the guide groove 24. The protective plate 29 is connected to the collar 27 through the connecting plate 28. Both the guide plate 210 and the guide groove 24 are designed in two sets and distributed on both sides of the slide groove 23. The stability of the movement of the collar 27 is achieved by the sliding of the guide plate 210 and the guide groove 24.

[0035] Specifically, a buffer plate 211 is provided on the outer wall of the protective plate 29, and a spring 212 is fixedly connected to the end of the buffer plate 211. The end of the spring 212 is fixedly connected to the end face of the protective plate 29. The buffer plate 211 can be made of flexible material to further protect the goods, and together with the spring 212, the elastic force of the spring 212 can provide a cushioning effect when the goods shake.

[0036] Working principle: First, the protective plates 29 around the storage plate 13 are moved to the edge of the storage plate 13. Then, the goods to be transported are placed on the upper surface of the storage plate 13. The first threaded rod 25 and the second threaded rod 26 are staggered and have a certain height difference. The center position of the first threaded rod 25 and the second threaded rod 26 is rotatably connected to the storage plate 13. The first threaded rod 25 and the second threaded rod 26 are manually controlled to rotate. The rotation of the oppositely spiraling grooves on the surfaces of the first threaded rod 25 and the second threaded rod 26 drives the collars 27 on both sides to move towards each other or in the same direction along their surfaces. The bottom of the protective plate 29 is provided with a guide plate 210. The sliding of the guide plate 210 in the guide groove 24 ensures the stability of the movement direction of the collars 27. Protective plates 29 are provided around the storage plate 13. The movement of the protective plates 29 can be used to position goods of different sizes and placement areas. The protection around the perimeter can provide a buffer protection for the goods.

[0037] The support plate 11 is then moved into the cargo compartment of the truck by the self-locking wheel 12. During the truck's transportation, the cargo is protected by the surrounding protective plates 29 and buffer plates 211. When the truck bumps, the cargo will shake. At this time, the elastic force of the spring 212 controls the buffer plate 211 to move adaptively in sync with the shaking range of the cargo, thereby providing further protection for the cargo.

[0038] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
