Abstract
Description
Technical Field
[0001] This utility model relates to a panel structure, a pallet panel splicing component and a splicing frame, and belongs to the field of pallet technology. Background Technology
[0002] Pallets are frequently used in high-bay warehouses and conveyor lines in the logistics warehousing and manufacturing industries as a carrier for stacking and storing various materials, achieving containerized storage and handling (used in conjunction with forklifts), improving logistics efficiency, and better ensuring the integrity of stored and handled materials to prevent damage. Pallets are one of the essential logistics equipment in modern logistics warehousing. A pallet is typically a frame structure on which goods can be stacked, and forklifts are used to move the pallets and the goods on them.
[0003] Pallets are the medium that transforms static goods into dynamic goods; they are a type of cargo platform, and a mobile platform, or movable ground. Dynamic loading and unloading methods using pallets as the basic tool are called pallet operations. Currently, various types of warehouses mainly use plastic pallets, wooden pallets, and steel pallets. Among them, the plastic pallets used in traditional automated warehouses have poor rigidity due to material issues, leading to frequent inbound alarms; they also have poor UV resistance, suffer severe aging from sunlight exposure, and have a short lifespan. While traditional wooden pallets are widely used, their heavy weight, susceptibility to damage, and non-reusability remain prominent problems. With the rapid development of e-commerce, the logistics and transportation industry has an increasing demand for efficient, environmentally friendly, and reusable pallets. Traditional steel pallets, on the other hand, use a lot of material, are heavy, costly, and not practical enough.
[0004] Furthermore, the existing pallets often have relatively thin bottom plates, resulting in weak load-bearing capacity, easy deformation, and premature replacement, thus reducing the pallet's lifespan. To improve their load-bearing capacity, the sub-panels are typically set to be 100mm wide, and multiple sub-panels are then assembled into a complete pallet panel. However, the narrow width of the sub-panels results in a larger number of parts in the manufacturing process, making production inconvenient and inefficient. Summary of the Invention
[0005] In order to overcome the shortcomings of the prior art, this utility model provides a panel structure, a tray panel splicing component, and a splicing frame.
[0006] The technical solution adopted by this utility model is as follows: a panel structure is designed, which includes a middle support part, edge support parts disposed on the left and right sides of the middle support part, and a load-bearing platform part connecting the middle support part and the edge support parts. The middle support part, the load-bearing platform part and the edge support parts are integrally formed and are made of a single steel plate bent into shape. The middle support part is an I-shaped structure, the edge support part is a C-shaped structure with the opening facing inward, and the load-bearing platform part is a rectangular thin plate with a reinforcing groove bent downward in the middle.
[0007] Furthermore, the intermediate support includes a first base plate, second base plates bent from the left and right sides of the first base plate toward the center of the first base plate, support plates bent upward from the adjacent ends of the two second base plates, and load-bearing plates bent outward from the two support plates.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0017] The tray structure of the present utility model is changed from a 100-panel to a 200-panel or 300-panel. The middle of the panel is roll-pressed into a "ji"-shaped (or I-shaped) by a rolling mill to ensure the intermediate supporting force.

[0030] Example 1
[0031] like Figure 1As shown, a panel structure includes a central support 1, edge support 2 located on the left and right sides of the central support 1, and a load-bearing platform 3 (for supporting and placing goods) connecting the central support 1 and the edge support 2. The central support 1, the load-bearing platform 3, and the edge support 2 are integrally formed from a single steel plate bent (rolled). The central support 1 has an I-shaped (or U-shaped) structure, providing strong support. The edge support 2 has a C-shaped structure, also providing some support. Especially when two panel structures are closely assembled, the C-shaped edge support 2 combine to form an I-shaped support structure, further enhancing the support capacity. The edge support 2 opens inward, facing the inside of the panel structure. The load-bearing platform 3 is a rectangular thin plate with a reinforcing groove 4 bent downward in the middle to strengthen the structural strength of the load-bearing platform 3 and improve its resistance to deformation.
[0032] In this embodiment, the intermediate support part 1 includes a first base plate 5, second base plates 6 that bend from the left and right sides of the first base plate 5 toward the middle of the first base plate 5 (and the second base plates 6 are located on the upper side of the first base plate 5 and are parallel to each other), support plates 7 that bend upward from the adjacent ends of the two second base plates 6, and bearing plates that bend outward from the two support plates 7 (at this time, the bearing plates and the bearing platform part 3 partially overlap).
[0033] In this embodiment, the panel structure is a 200mm-300mm wide panel structure, which can reduce the number of panel structures required for subsequent pallet panel splicing assembly, reduce costs, improve manufacturing efficiency, and achieve cost reduction and efficiency improvement.
[0034] Example 2
[0035] This embodiment provides a tray panel splicing assembly, such as Figure 2-3 As shown, it includes the panel structure described in Embodiment 1, and also includes two baffles 8 and two protective plates 9. The tray panel splicing assembly is formed by welding the panel structure, baffles 8 and protective plates 9 together.
[0036] More specifically, the pallet panel splicing assembly adopts a multi-panel structure that is closely arranged from left to right to form a base panel. Then, a baffle 8 is set on the left and right sides of the panel to protect the left and right sides. A guard plate 9 is set on the front and rear sides of the base panel to protect the front and rear ends.
[0037] In this embodiment, the baffle 8 is made of a rectangular tube, and the guard plate 9 is made of a bent rectangular plate, including a horizontal fastening part 10, a vertical protective part 11 and an inclined protective part 12, which are integrally formed. The horizontal fastening part 10 is pressed on the upper surface of the panel structure and the baffle 8, the vertical protective part 11 is blocked at the port of the panel structure and the baffle 8, and the inclined protective part 12 is folded down below the panel structure.
[0038] Example 3
[0039] This embodiment provides a pallet splicing frame, such as Figure 4-6 As shown, it includes the pallet panel splicing assembly described in Embodiment 2, and also includes a bottom leg assembly, with multiple sets of bottom leg assemblies disposed on the lower side of the pallet panel splicing assembly.
[0040] Steel pallets are suitable for forklift operations, facilitating the storage and retrieval of goods. They are primarily used for multi-purpose ground storage, rack storage, and intermodal transport and turnover of goods—a series of ultra-lightweight metal pallets. Steel pallets are available in four-way and two-way forklift configurations. With four-way forklift pallets, forklifts can insert into the bottom of the pallet from four directions, enabling the transfer of goods. In this embodiment, the pallet splicing frame (i.e., the pallet) adopts a four-way forklift design.
[0041] Example 4
[0042] This embodiment is a further optimization and refinement of the pallet splicing frame structure based on embodiment 3, specifically as follows:
[0043] In this embodiment, the pallet splicing frame has three sets of bottom leg components on the lower side of the pallet panel splicing assembly to provide support for its two ends and the middle, respectively; and the three sets of bottom leg components form a fork entry channel. At the same time, the bottom leg components are provided with two fork entry channels, thereby enabling four-way fork entry and facilitating forklift operation.
[0044] The base assembly includes a top beam 13, a ground beam, and support columns 14. The top beam 13 and the ground beam are arranged parallel to each other vertically and are connected by two support columns 14. The structure is simple, has high support strength, and provides stable and reliable support.
[0045] Example 5
[0046] This embodiment is a further optimization and refinement of the base leg assembly structure based on Embodiment 4, specifically as follows:
[0047] The pallet splicing frame described in this embodiment further includes an end plate 15 in the bottom leg assembly. An end plate 15 is provided at both ends of the top beam 13 and the ground beam. The end plate 15 is an M-shaped bent plate. The bottom leg assembly located at both ends of the pallet panel splicing assembly also includes a sealing plate 16. The sealing plate 16 is located between the two support columns 14 and on the outside of the support columns 14, forming a certain closed environment to reduce the entry of foreign objects into the lower part of the pallet.
[0048] Example 6
[0049] This embodiment is a further optimization and refinement of the base leg assembly structure based on Embodiment 5, specifically as follows:
[0050] The base leg assembly described in this embodiment has a ground beam that is a polyethylene beam, which includes a polyethylene clamping plate 17 and a polyethylene pad 18. The polyethylene clamping plate 17 has a slot on its lower side, and the polyethylene pad 18 is clamped into the slot on the lower side of the polyethylene clamping plate 17. The two are detachably connected by bolts or the like.
[0051] The bottom of the pallet is prone to wear. A removable polyethylene pad 18 facilitates replacement and provides good anti-slip properties. This application's use of polyethylene legs on steel pallets offers the following advantages: lightweight and portability: Polyethylene has a much lower density than steel, significantly reducing the overall weight of the pallet, facilitating handling and installation, and lowering transportation costs. Corrosion and weather resistance: Polyethylene is highly resistant to acids, alkalis, salts, oils, and humid environments, avoiding the rust problems common with metal legs and extending service life. Shock absorption and impact resistance: The elasticity and impact resistance of polyethylene effectively absorb vibrations from equipment operation or uneven ground, reducing damage to the pallet structure and the ground. Insulation protection: As an insulating material, polyethylene legs can block current conduction, preventing safety hazards caused by metal conductivity during electrical work or thunderstorms. Wear resistance and durability: The high wear resistance of polyethylene reduces wear from friction between the legs and the ground, complementing the high load-bearing capacity of the steel pallet. Environmentally friendly and cost-effective, polyethylene is recyclable and can be used for a long time without the need for anti-corrosion maintenance, and its overall cost is lower than that of wooden or single metal legs that require frequent replacement.
[0052] The application scenarios for this application include:
[0053] 1. Manufacturing: Material transfer on the production line to improve production efficiency.
[0054] 2. Logistics industry: Loading, unloading, stacking and transferring goods to reduce damage rates and save costs.
[0055] 3. Retail industry: a platform for product storage and display, enhancing brand image.
[0056] 4. Agriculture and food industry: Hygienic and corrosion-resistant, ensuring food safety and hygiene.
[0057] Furthermore, in the description of this utility model, unless otherwise stated, the terms "multiple," "multiple roots," and "multiple groups" mean two or more, and "several," "several roots," and "several groups" mean one or more. In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on this utility model.
