For example, in stable production processes, steel pallets are often used to transfer workpieces, allowing them to be moved between different processes.

[0003] In related technologies, the top of a metal pallet is usually a flat surface. When workpieces such as stables and iron railings are placed on the metal pallet and transported, the workpieces are prone to falling off. Although existing technologies can prevent workpieces from falling off by adding a barrier around the metal pallet, the barrier affects the efficiency of workpiece handling, and the height of the barrier is usually fixed, which means that stacked metal pallets require more space and affect the storage of metal pallets. Based on this, this application proposes a stackable metal pallet structure. Utility Model Content

[0023] 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.

[0024] This utility model provides a stackable iron pallet structure, including a first support frame and a second support frame. The first support frame and the second support frame are connected by a bearing plate 5. A positioning groove is formed between two adjacent bearing plates 5. Positioning blocks 7 are fixedly connected to the bottom of both the first support frame and the second support frame. The positioning blocks 7 are adapted to the positioning groove. By setting the positioning blocks 7 and the positioning groove, the iron pallet can be positioned to ensure the verticality of the stacked iron pallets in the vertical direction and improve the stability of the iron pallets when stacked.

[0025] The first support frame includes an outer support plate 1 and an inner support plate 2. The inner support plate 2 has a positioning structure, which includes a toothed plate 8 movably connected to the inner support plate 2 and a rotating roller 12 movably connected to the top of the inner support plate 2. The rotating roller 12 is located on the side of the inner support plate 2 closest to the outer support plate 1. A gear 10 is fixedly connected to the outer ring of the rotating roller 12, and the gear 10 meshes with the toothed plate 8. A spring groove is provided in the middle of the toothed plate 8, and a spring 11 is fixedly connected inside the spring groove. The inner side of the outer support plate 1 has a slot 15 that matches the toothed plate 8. The other end of the spring 11 is fixedly connected to the inner wall of the slot 15. A limiting plate 16 is fixedly connected to the side of the toothed plate 8 away from the outer support plate 1. The inner support plate 2 is located between the gear 10 and the limiting plate 16. As described above, the toothed plate 8 can move under the action of external force. When the toothed plate 8 moves, it drives the gear 10 that meshes with it. The gear 10 drives the rotating roller 12 that is fixedly connected to it to rotate. Positioning rods 9 are fixedly connected to the outer rings at both ends of the rotating roller 12. When the rotating roller 12 rotates, it can drive the positioning rods 9 that are fixedly connected to it to rotate. When the restriction on the toothed plate 8 is released, the rebound force of the spring 11 can drive the toothed plate 8 to reset. The toothed plate 8 drives the gear 10 to mesh. The gear 10 drives the positioning rod 9 to rotate in the opposite direction through the rotating roller 12. When the toothed plate 8 resets, the positioning rod 9 is in a horizontal state. The top of the positioning rod 9 is not higher than the top of the bearing plate 5. Preferably, the height of the positioning rod 9 is the same as the height of the bearing plate 5.

[0026] A push plate 13 is fixedly connected to the side of the toothed plate 8 near the outer support plate 1. Both ends of the push plate 13, the outer support plate 1, and the inner support plate 2 are provided with forklift holes 6 adapted to forklifts.

[0027] The second support frame includes an outer support plate 4 and another inner support plate 2. The other inner support plate 2 is provided with another positioning structure, which includes another toothed plate 8 movably connected to the other inner support plate 2, another rotating roller 12 movably connected to the top of the other inner support plate 2, another gear 10 fixedly connected to the outer ring of the other rotating roller 12, and another positioning rod 9 fixedly connected to the outer ring of the other rotating roller 12. The other positioning rod 9 is offset from the positioning rod 9 in the first support frame. The other gear 10 meshes with the other toothed plate 8. The other toothed plate 8 is connected to the outer support plate 4 through another spring 11. The inner side of the outer support plate 4 is provided with another slot 15. The middle part of the other toothed plate 8 is provided with a spring groove. One end of the other spring 11 is fixedly connected to the inner wall of the spring groove, and the other end of the other spring 11 is fixedly connected to the inner wall of the other slot 15. The end of the other toothed plate 8 away from the outer support plate 4 is fixedly connected to another limiting plate 16. The other inner support plate 2 is located between the other limiting plate 16 and the other rotating roller 12.

[0028] Another toothed plate 8 is fixedly connected to a push plate 14 near the side of the outer support plate 2 4. Both ends of the push plate 14, the outer support plate 2 4, and the inner support plate 2 are provided with forklift holes 3 adapted to the forklift. The forklift holes 3 are offset from the forklift hole 6. Both the push plate 1 13 and the push plate 14 are located below the roller 12 and below the positioning rod 9. The lengths of the push plate 13 and the push plate 14 are the same. The forklift hole 3 and the forklift hole 6 are at the same height, and the end of the push plate 13 is located on the straight line of the forklift hole 3, while the end of the push plate 14 is located on the straight line of the forklift hole 6. With the arrangement of push plate 13 and push plate 14, when the forklift forks are inserted into the inner cavity of forklift hole 2 3, the forks will press against push plate 13. Push plate 13 can drive the toothed plate 8 connected to it to move, thereby allowing the positioning rod 9 to change from a horizontal state to a vertical state. The positioning rod 9 limits the workpieces such as fences and stables placed on the iron pallet. When the forklift is separated from the iron pallet, the positioning rod 9 can be reset under the action of the spring 11, which facilitates the stacking of iron pallets and the loading and unloading of workpieces. When the forklift forks are inserted into forklift hole 1 6, the forks can push push plate 2 14 to move, so that the iron pallet can be loaded and unloaded from multiple directions, improving the adaptability of the iron pallet.

[0029] In practical applications, an inner support plate 2 can be added between the first support frame and the second support frame as needed to ensure the strength of the iron pallet.

[0030] In summary, this stackable iron pallet structure is suitable for transporting workpieces such as stables and iron fences. The following example, using the iron pallet for transporting iron fences and the forklift forks inserted into the forklift hole 2 3, will further illustrate this application.

[0031] When using this stackable iron pallet structure, the operator adjusts the distance and length of the two positioning rods 9 in the positioning structure according to the distance between two adjacent vertical bars in the iron fence. When the iron fence is placed on the iron pallet, the positioning rod 9 is located between two adjacent vertical bars in the iron fence. When the iron pallet needs to be transferred, the forklift forks are inserted into the forklift hole 3. During the insertion of the forks, the push plate 13 can be squeezed. The push plate 13 can drive the toothed plate 8 connected to it to move until the positioning rod 9 changes from a horizontal state to a vertical state. The positioning rod 9 can limit the iron fence to prevent it from falling off during the transfer. After the forks are separated from the iron pallet, the toothed plate 8 returns to its original position under the action of the spring 11. The toothed plate 8 drives the gear 10 meshing with it to rotate in the opposite direction. The gear 10 drives the rotating roller 12 fixedly connected to it to rotate in the opposite direction. The rotating roller 12 drives the positioning rod 9 to rotate in the opposite direction. The positioning rod 9 changes from a vertical state to a horizontal state, which facilitates the picking and placing of workpieces on the iron pallet. Furthermore, during the stacking process, the positioning block 7 is inserted into the positioning groove, which improves the stability of the stacked iron pallets.
