[0001] The utility model relates to the technical field of trays for cartons, in particular to a wooden tray facilitating the stacking of multiple layers of cartons. Background Art

[0002] Wooden trays are the earliest materials used as trays. They are convenient for obtaining materials, easy to manufacture and repair, and have low costs, and have always occupied a dominant position in the tray market. Carton packaging of goods has the advantages of being light, dust-proof, foldable, good airtightness, etc., and is widely used. However, due to the low compressive strength of cartons, usually only one carton is placed on a wooden tray for transportation in actual applications.

[0003] Chinese Patent CN201920594650.1 discloses a tray coil packing box, in which only one carton can be placed for transportation, greatly reducing the utilization rate of the tray and increasing the manufacturing and transportation costs. In addition, for existing wooden trays, anti-collision protection is usually not provided for the corners of cartons, increasing the risk of the goods inside the box being impacted. If anti-collision protection is provided for the corners of cartons, a circle of protection plates is set on the outer periphery of the cartons, with a complex structure, more materials used, and inconvenient use. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a wooden tray facilitating the stacking of multiple layers of cartons, which can solve the problems in the prior art such as low utilization rate of wooden trays, increased manufacturing and transportation costs, high risk of the goods inside the cartons being impacted, complex structure, more materials used, and inconvenient use caused by setting a circle of protection plates to achieve the anti-collision function.

[0021] In order to make the purpose, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in combination with the accompanying drawings and specific implementation manners. The following embodiments can enable those skilled in the art to understand the present utility model more comprehensively, but do not limit the present utility model within the scope of the described embodiments.

[0022] As Figures 1-3 shown, the following technical solutions are adopted in this specific implementation manner: It includes a base 1, an intermediate partition 2 and an upper cover plate 3; the base 1 is rectangular, the intermediate partition 2 is also rectangular, and the intermediate partition 2 is in a cross-shaped frame structure for supporting the upper-layer carton 10. The length and width of the intermediate partition 2 are respectively the same as the length and width of the base 1; the upper cover plate 3 is also rectangular, and the upper cover plate 3 is in a square frame structure. The length and width of the upper cover plate 3 are respectively the same as the length and width of the base 1.

[0023] At the four top corners of the top of the base 1, there are right-angle limit blocks 4 for limiting the bottom of the lower-layer carton 10. The outer edge of the right-angle limit block 4 on the base 1 is flush with the outer edge of the base 1 to ensure the stability of the carton 10 on the wooden pallet base 1.

[0024] There is at least one intermediate partition 2 between the base 1 and the upper cover plate 3 for stacking the cartons 10 up and down. At the two sides of the top and bottom of the intermediate partition 2, there are U-shaped limit blocks 5. The outer edge of the U-shaped limit block 5 arranged on the intermediate partition 2 is flush with the outer edge of the intermediate partition 2 for front-back, left-right limiting and fixing of the upper and lower-layer cartons 10, improving the stability of the cartons 10 on the wooden pallet base 1. The U-shaped design reduces the risk of the side of the carton 10 being impacted.

[0025] At the four corners of the bottom of the upper cover plate 3, there are right-angle limit blocks 4 for limiting the top of the carton 10. The outer edge of the right-angle limit block 4 on the upper cover plate 3 is flush with the outer edge of the upper cover plate 3 for anti-wear and anti-collision protection of the upper-layer carton 10, and for limiting and fixing the upper-layer carton 10, improving the stability of the upper-layer carton 10 on the wooden pallet base 1.

[0026] The middle partition 2 is supported and limited between the base 1 and the upper cover plate 3 through a support structure. The support structure includes support columns 6. A limit groove 7 for sleeving the support columns is provided on the right-angle limit block 4 at the top of the base 1. Limit grooves 7 for sleeving the support columns 6 are also provided on the U-shaped limit blocks 5 arranged at the top and bottom of the middle partition 2. Limit grooves 7 for sleeving the support columns 6 are also provided on the right-angle limit blocks 4 at the bottom of the upper cover plate 3. The limit grooves 7 are respectively arranged at the top corners of the right-angle limit blocks 4 and the U-shaped limit blocks 5. The support columns 6 are sleeved in the limit grooves 7 on the corresponding right-angle limit blocks 4 and U-shaped limit blocks 5 to support and limit the middle partition 2 between the base 1 and the middle partition 2 between the upper cover plate 3. By designing the middle partition 2, and the middle partition 2 is supported on the base 1 through the support structure, the middle partition 2 will not press on the lower-layer carton 10. The carton 10 is less stressed, and the cartons 10 can be stacked and used in multiple layers, solving the problem of poor compressive resistance of the cartons 10 and greatly improving the utilization rate of the wooden pallet.

[0027] Working principle: When transporting the carton 10, place the carton 10 on the base 1 of the wooden pallet. The right-angle limit block 4 on the base 1 can limit the carton 10. To increase the transportation efficiency, stack the cartons 10. First, place the middle partition 2 above the carton 10 on the base 1 and support the middle partition 2 on the base 1 through the support structure, that is, sleeve the support columns 6 in the limit grooves 7 on the corresponding right-angle limit blocks 4 and U-shaped limit blocks 5 of the base 1 and the middle partition 2. The middle partition 2 is supported and will not press on the lower-layer carton 10. The lower-layer carton 10 is less stressed. By arranging the U-shaped limit blocks 5 on both sides of the upper and lower surfaces of the middle partition 2, the upper and lower-layer cartons 10 can be limited and fixed, improving the stability of the carton 10 on the base of the wooden pallet and effectively avoiding the problem that the goods in the carton 10 are damaged by collision due to shaking during transportation. And so on, several middle partitions 2 can be used to stack and use the cartons 10 in multiple layers, improving the utilization rate of the wooden pallet, reducing the production and transportation costs. Moreover, the support columns 6 of the support structure are connected to the right-angle limit blocks 4 and the U-shaped limit blocks 5 through the limit grooves 7. The support structures of the middle partition 2 and the upper cover plate 3 are simple, use less materials, are flexible in disassembly and assembly, and are more convenient to use. After stacking, install the upper cover plate 3 on the top-layer carton 10, and set right-angle limit blocks 4 at the bottom corners of the upper cover plate 3 to improve the overall stability of the carton 10 on the wooden pallet and reduce the risk of the corners of the carton 10 being impacted. When unloading after transportation, the upper cover plate 3, the support columns 6, and the middle partition 2 can be disassembled respectively, which is convenient to use.
