Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0016] A special pallet device for logistics, such as Figure 1 、 2As shown, it includes a base 1, wherein the four sides of the base 1 are respectively plugged and matched with square tubes 2, each of which is provided with a through slot 3, and two screws 4 are respectively rotatably provided in the square tube 2, and the two corresponding screws 4 are symmetrically arranged. The screws 4 are respectively threaded and matched with nuts 5, and the nuts 5 are respectively connected to the base 1 through connecting rods 6 passing through the through slot 3. One end of the connecting rod 6 is rotatably mounted on the nut 5 via a hinge shaft, and the other end of the connecting rod 6 is rotatably mounted on the base 1 via a hinge shaft, and a driving mechanism for driving the corresponding two screws 4 to rotate simultaneously is respectively provided on the square tube 2. The utility model has a simple structure and an ingenious design. The square tubes 2 around the base 1 can all move outward, thereby avoiding the occurrence of the problem of load center of gravity offset and instability caused by one side or both sides, increasing the load-bearing area, simple operation, meeting market demand, and being suitable for promotion. When the utility model is used, the driving mechanism can drive the two screws 4 on the corresponding side to rotate simultaneously. The rotation of the screw 4 can drive the corresponding nut 5 to move to both sides, thereby driving the corresponding connecting rod 6 to rotate. The rotation of the connecting rod 6 can push the square tube 2 to expand outward, thereby increasing the bearing area of ​​the goods on the base 1, making it convenient to store and transport more goods. Moreover, since the four sides of the base 1 can be expanded outward, the problem of unstable center of gravity of the goods stored on the base 1 will not occur.

[0017] Specifically, as shown in the figure, two fixing plates 20 are fixedly provided in the square tube 2 of this embodiment. The corresponding two fixing plates 20 are symmetrically arranged. One end of the screw rod 4 is rotatably mounted on the fixing plate 20 via a bearing, and the other end of the screw rod 4 is rotatably mounted on the square tube 2 via a shaft seat. The outer periphery of the screw rod 4 is fixedly connected to the inner periphery of the bearing and the inner periphery of the shaft seat. The outer periphery of the bearing is fixedly mounted on the fixing plate 20, and the outer periphery of the shaft seat is fixedly mounted on the square tube 2. The provision of the fixing plates 20 and the shaft seat can increase the rotational stability of the screw rod 4 and facilitate use.

[0018] Specifically, as shown in the figure, the drive mechanism of this embodiment includes a first bevel gear 30. The inner ends of the screw rods 4 that are close to each other are respectively fixedly mounted with the coaxial first bevel gears 30. One side of the first bevel gear 30 is meshed with a second bevel gear 31. The second bevel gear 31 is fixedly mounted with a coaxial hexagon socket bolt 32. The outer periphery of the hexagon socket bolt 32 is rotatably mounted on a reserved hole opened in the square tube 2 via a bearing. The outer periphery of the hexagon socket bolt 32 is fixedly connected to the inner periphery of the bearing, and the outer periphery of the bearing is fixedly mounted on the reserved hole. By using an hexagon socket wrench to rotate the hexagon socket bolt 32, the second bevel gear 31 can be driven to rotate. The second bevel gear 31 can drive the first bevel gear 30 and the two screw rods 4 on both sides to rotate simultaneously.

[0019] Furthermore, as shown in the figure, the base 1 of this embodiment is provided with a plurality of slots (not shown in the figure) around its periphery. Each slot is provided with a rod 40 for insertion and engagement therewith. The rod 40 is fixedly mounted on the corresponding square tube 2. When the square tube 2 is moved outward, the rod 40 is driven out of the corresponding slot. The rod 40 can increase the support effect between the square tube 2 and the base 1, making it easier to use.

[0020] Furthermore, as shown in the figure, in this embodiment, adjacent corners of the square tubes 2 are respectively fitted with a fixed block 50, and two insert plates 51 are fixed to the fixed block 50. The insert plates 51 can be inserted into the interior of the corresponding square tube 2. When the square tube 2 moves, the fixed block 50 at the corresponding corner is driven out of the adjacent square tube 2. The fixed block 50 can increase the load-bearing area and facilitate use.

[0021] Furthermore, as shown in the figure, in this embodiment, a plurality of support seats 60 are fixedly provided on the base 1 and the square tube 2 and are spaced apart. Support seats 60 are also fixedly provided on the fixing block 50. A plurality of square slots 61 are formed on the base 1. The support seats 60 can support the base 1 and the square tube 2, while facilitating the insertion of a forklift between the spaced support seats 60. The square slots 61 facilitate ventilation and storage of goods.
