Description

Technical Field

[0001] This utility model relates to the field of wooden pallet technology, and in particular to a wooden pallet with a spreading structure. Background Technology

[0002] In the logistics and warehousing sector, wooden pallets serve as crucial tools for carrying and handling goods, and their structural rationality directly impacts the stability of storage and transportation efficiency. Currently, most wooden pallets have a fixed load-bearing area. When dealing with large or irregularly shaped goods, these fixed-area pallets are often unsuitable, leading to sagging edges, instability, and increased risk of damage during transport. Replacing them with larger pallets increases warehousing costs and wastes resources.

[0003] Furthermore, in actual use, some pallets with extension functions suffer from insufficient support stability of the extension structure. After extension, they are prone to deformation or swaying under load, failing to reliably ensure the safety of goods. At the same time, the ease of operation and storage rationality of the extension mechanism need improvement; complex structural designs reduce efficiency and negatively impact user experience. Therefore, there is an urgent need for a wooden pallet that can flexibly adjust the load-bearing area, provides stable support after extension, and is easy to operate, in order to address the shortcomings of existing technologies. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, one of the objectives of this utility model is to provide a wooden pallet with a spreading structure.

[0005] One of the objectives of this utility model is achieved through the following technical solution: A wooden pallet with an expandable structure includes a pallet body, on both the front and rear sides of the pallet body having expandable extension mechanisms, and support legs fixedly connected to the bottom of the pallet body near the front and rear sides. A limit block is fixedly connected to the middle of the bottom of the pallet body, and a forklift fork hole is formed between the limit block and the two support legs.

[0006] The spreading and extending mechanism includes grooves respectively formed on the front and rear sides of the pallet body. The inner cavity of each of the two grooves is fitted with an extension plate, and the side of each extension plate away from the pallet body is fixedly connected with a handle.

[0007] Each of the two extension plates has a storage slot at the bottom center, and each storage slot has a support rod inside. The end of each support rod away from the tray body is fixedly connected to a connecting shaft, and the left and right ends of the two connecting shafts are movably connected to the left and right inner walls of the storage slots, respectively.

[0008] Each of the two support rods has a first threaded hole near its corresponding end.

[0009] Two reinforcing blocks are fixedly connected to the side of each of the two support legs away from the pallet body, and several reinforcing blocks are further fixedly connected to the support legs by several connecting bolts.

[0010] Each of the reinforcing blocks has a second threaded hole, and the two support rods are fixedly connected by screws and nuts that pass through adjacent first threaded holes and second threaded holes.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. Flexible adjustment of load-bearing area to accommodate various goods: By setting up an extension mechanism on the front and rear sides of the pallet body, the extension plate can be pulled out from the groove, effectively expanding the load-bearing area of ​​the pallet, which can accommodate goods of different sizes, avoid the problem of goods hanging, improve the stability of goods placement, and reduce transportation losses.

[0012] 2. Stable and reliable support after extension: The bottom of the extension plate is equipped with a rotatable support rod, which is movably connected to the storage groove through a connecting shaft. After the extension plate is pulled out, the support rod can be lowered, and the support rod and the reinforcing block on the support leg can be fixed with screws and nuts (through the first threaded hole and the second threaded hole), forming a stable support structure, effectively distributing the load of the extension part, preventing the extension plate from deforming or shaking due to force, and ensuring safety in use.

[0013] 3. High structural strength and durability: The outer side of the support leg is fixedly connected to a reinforcing block and further reinforced by connecting bolts, which enhances the load-bearing capacity of the support leg and the overall structural strength; at the same time, the threaded connection between the support rod and the reinforcing block ensures the reliability of the support and extends the service life of the pallet.

[0014] 4. Easy to operate and reasonably stored: The extension plate can be easily pulled out or pushed into the groove using the handle, and the support rod can be stored in the storage slot at the bottom of the extension plate without taking up extra space. The operation is simple and convenient, improving the efficiency of use.

[0015] 5. Compatible with forklift handling and highly practical: The bottom of the pallet forms forklift fork holes through the limit blocks and support legs, retaining the forklift handling function of traditional pallets. This ensures that goods can still be easily transferred after adjusting the load-bearing area, balancing flexibility and practicality.

[0022] I. Component Specifications and Initial State The wooden pallet described in this embodiment is suitable for carrying and transferring small to medium-sized goods in logistics warehousing. Its specific structure and initial state are as follows: The tray body 1 is made of pine wood and is rectangular in shape, with a length of 1200mm, a width of 800mm, and a thickness of 50mm. The front and back sides are symmetrically provided with grooves 4 along the length direction. The grooves 4 are 1200mm long, 200mm wide, and 40mm deep, and are used to store the extension board 2.

[0023] Extending mechanism: includes two extension plates 2 that fit the groove 4. The extension plates 2 are also made of pine wood, with a length of 1200mm, a width of 200mm, and a thickness of 40mm. A solid wood handle 3 with a length of 100mm and a diameter of 30mm is fixedly connected to the middle of the side away from the pallet body 1, which is convenient for operators to push and pull. A storage groove 9 is opened in the middle of the bottom of the extension plate 2 along the length direction. The storage groove 9 is 1100mm long, 50mm wide, and 30mm deep, and is used to store the support rod 10.

[0024] Support structure: Four support legs 5 made of pine wood are symmetrically fixed to the front and rear sides of the bottom of the pallet body 1. They are 150mm high and have a cross-section of 100mm×100mm. A limiting block 7 made of pine wood is fixedly connected to the middle of the bottom. It is 150mm high and has a cross-section of 80mm×80mm. Two forklift fork holes 6 are formed between the limiting block 7 and the two support legs 5. The fork holes 6 are 200mm wide and 150mm high, and are adapted to the standard forklift fork tooth size.

[0025] Reinforcing components: Each support leg 5 has two iron reinforcing blocks 13 fixedly connected to the side away from the pallet body 1. The iron blocks are 80mm long, 50mm wide, and 10mm thick. The reinforcing blocks 13 are fastened to the support leg 5 by four M8 connecting bolts. The extension plate 2 has a support rod 10 made of pine wood in the storage groove 9. The support rod 10 is 1100mm long, 45mm wide, and 25mm thick. The end of the support rod 10 away from the pallet body 1 is movably connected to the inner wall of the storage groove 9 by a 10mm diameter iron connecting shaft 8. The two ends of the connecting shaft 8 are embedded in the left and right inner walls of the storage groove 9 and can rotate freely. The end of the support rod 10 near the pallet body 1 has a first threaded hole 15M6. The corresponding position on the reinforcing block 13 has a second threaded hole 16. Screws 11M6×30mm and nuts 14M6 are provided to fix the support rod 10.

[0026] II. Actual Operation Procedures 1. Status when extended functions are not used In its initial state, the extension plate 2 is fully fitted and stored in the groove 4, and the support rod 10 is rotated into the storage slot 9 through the connecting shaft 8. The overall structure is compact, and the pallet bearing area is 1200mm×800mm. It can be directly used for placing goods of regular size. The forklift forks can be inserted through the forklift fork hole 6 for handling. The limit block 7 can prevent the forklift forks from deviating and ensure the stability of handling.

[0027] 2. Operational adaptation for extra-long cargo when the carrying capacity needs to be expanded. When the length of the goods exceeds the width of the pallet body 1, such as when the width of the goods is 1000-1200mm, the operating steps are as follows: Pull out the extension plate: The operator holds the handle 3 and pulls the extension plate 2 outward along the groove 4 until the extension plate 2 is fully extended out of the groove 4. At this time, the total load-bearing width of the pallet is expanded to 800mm + 200mm × 2 = 1200mm, and the front and rear extension plates extend 200mm each.

[0028] Unfold the support rod: Rotate the support rod 10 in the storage groove 9 at the bottom of the extension plate 2 downward by 90° through the connecting shaft 8, so that the support rod 10 is perpendicular to the bottom of the extension plate 2 and the lower end is parallel to the ground.

[0029] Fixed support structure: Align the first threaded hole 15 of the support rod 10 with the second threaded hole of the reinforcing block 13 on the support leg 5, pass the screw 11 through the two threaded holes, and tighten it with the nut 14 to make the support rod 10 and the support leg 5 form a rigid connection, thereby dispersing the load-bearing pressure of the extension plate 2.

[0030] 3. Placement and handling of goods After the extension is completed, the extra-long goods are placed stably on the pallet body 1 and the two side extension plates 2. The weight of the goods is transferred to the support legs 5 through the pallet body 1. At the same time, the weight of the extension plates 2 is transferred to the reinforcing block 13 and the support legs 5 through the support rod 10, so as to prevent the extension plates 2 from deforming due to the load. When the forklift is handling, the fork teeth are still inserted through the forklift fork hole 6. The limiting block 7 ensures that the fork teeth are accurately positioned. The overall structure of the extended pallet is stable and there is no risk of shaking.

[0031] 4. Storage after completing the task After the goods are unloaded, the extension structure needs to be stowed away to save storage space. Loosen nut 14 and remove screw 11 to release the support rod 10 from the reinforcing block 13; The support rod 10 is rotated upwards into the storage slot 9 via the connecting shaft 8 to ensure a complete fit for storage. Hold handle 3 and push extension plate 2 back into groove 4 to restore the initial compact state.

[0032] III. Advantages of the Implementation Examples This embodiment achieves flexible adjustment of the pallet's load-bearing area through a modular expansion mechanism, adapting to goods of different sizes; the rigid connection between the support rod and the reinforcing block ensures the stability of the support after extension, preventing goods from shaking or pallet deformation; the operation process is simple and convenient, requiring no complicated tools to complete the expansion and storage, taking into account both practicality and safety, and is suitable for various logistics and warehousing scenarios.
