Description

Technical Field

[0001] This utility model relates to the field of logistics and warehousing equipment technology, specifically to pallets. Background Technology

[0002] Pallets, as indispensable unitized loading equipment in modern logistics warehousing, are widely used in cargo handling, stacking, and transportation. For a long time, traditional pallets have mostly adopted a one-piece structure, primarily made of wood, plastic, or metal. While these pallets can meet basic requirements in terms of load-bearing strength and durability, their inherent one-piece structure leads to many insurmountable drawbacks. First, because the structure cannot be disassembled, they occupy a huge amount of space during empty-load recovery or storage, resulting in serious waste of transportation costs and storage space, and extremely low space utilization.

[0003] To overcome the aforementioned drawbacks, some detachable or foldable pallet designs have emerged in existing technologies. However, the connection structure of pallets is usually quite complex, involving various specialized connectors, intricate clips, or requiring the use of wrenches, screwdrivers, or even specific installation tools to complete assembly and disassembly. This complexity directly leads to cumbersome and time-consuming operations, significantly reducing the efficiency of logistics operations and making it difficult to meet the requirements of modern supply chains for high efficiency and rapid response. Utility Model Content

[0004] To address the technical problem of complex pallet connection structures in existing technologies, this utility model proposes a pallet that allows for rapid switching between the first and second states via a pin, eliminating the need for specialized tools such as wrenches, screwdrivers, and hammers, thus greatly reducing the operational threshold and tool costs.

[0005] The technical solution adopted by this utility model is as follows: A pallet includes a panel, a base plate, legs, and a pin, wherein a limiting block is provided at one end of the pin, and a strip-shaped locking block is provided at the other end of the pin; the panel, legs, and base plate are respectively provided with strip-shaped holes for the strip-shaped locking block to pass through, and the diameter of the limiting block is larger than the diameter of the strip-shaped hole; the pin has a first state and a second state. In the first state, the direction in which the strip-shaped locking block extends outward relative to the pin is consistent with the length direction of the strip-shaped hole, and the pin passes through the strip-shaped hole; in the second state, the direction in which the strip-shaped locking block extends outward relative to the pin is at an angle to the length direction of the strip-shaped hole, and the upper surface of the strip-shaped locking block abuts against the lower surface of the strip-shaped hole of the base plate.

[0006] Optionally, both the strip hole in the panel and the strip hole in the base plate are countersunk holes. The top surface of the countersunk hole wall of the strip hole in the panel is provided with at least one slot, and the bottom surface of the limiting block is provided with a protrusion that cooperates with the slot. When the pin is in the second state, the protrusion is engaged in the slot.

[0007] Optionally, there are two strip-shaped blocks, which are symmetrically arranged on both sides of the end of the pin. The strip-shaped hole includes an arc-shaped hole for the shaft rod of the pin to pass through and two irregular holes for the strip-shaped blocks to pass through. The two irregular holes are respectively connected to the arc-shaped hole.

[0008] Optionally, the support leg includes a support plate and a support column fixedly disposed inside the support plate. Both ends of the support column protrude from the support plate. The support column is provided with the strip-shaped hole, and the strip-shaped hole passes through both ends of the support column. The side of the panel facing the support leg and the side of the base plate facing the support leg are respectively provided with grooves that match the shape of the end of the support column.

[0009] Optionally, the bottom surface of the base plate is detachably provided with a cover, and the base plate is provided with a through hole that matches the shape of the cover, and the through hole is connected to the strip hole; when the pin is in the second state, the cover closes the through hole.

[0010] Optionally, the cover has limiting protrusions on both sides, and the sidewall of the through hole has a limiting groove that matches the limiting protrusions.

[0011] Optionally, the bottom surface of the cover is provided with an anti-slip surface.

[0012] Optionally, the number of the support legs is multiple, and the multiple support legs are arranged in an array between the panel and the base plate.

[0013] The beneficial effects of this invention are as follows: The assembly process requires only three simple steps: manually aligning the holes, inserting the pin, and rotating it. No special tools such as wrenches, screwdrivers, or hammers are needed, greatly reducing the operational threshold and tool costs. The pin's first and second states transition rapidly, and a single rotation locks a single connection point. Compared to traditional bolt tightening or snap-fit ​​methods, assembly speed is increased several times, making it particularly suitable for logistics scenarios requiring frequent disassembly and rapid deployment. If a component, such as a support leg or pin, is damaged, the damaged part can be quickly replaced simply by reversing the operation, without scrapping the entire pallet. This modular repair significantly extends the overall product lifecycle and aligns with the concepts of green environmental protection and sustainable development. Attached Figure Description

Detailed Implementation

[0020] The present application will now be described in further detail with reference to the accompanying drawings and embodiments.

[0021] like Figs. 1 to 5 As shown, this embodiment discloses a pallet, including a front panel 1, a bottom plate 2, a plurality of legs 3 arranged in an array between the front panel 1 and the bottom plate 2, and pins 4 for connecting and fixing the three together.

[0022] One end of the pin 4 is provided with a limiting block 41, and the other end is provided with a strip-shaped locking block 42. Correspondingly, strip-shaped holes 5 for the pin 4 to pass through are provided at corresponding positions on the panel 1, the support leg 3 and the base plate 2. The diameter of these strip-shaped holes 5 is designed to allow the shaft of the pin 4 and the strip-shaped locking block 42 at its end to pass smoothly under a specific orientation, that is, when the direction in which the strip-shaped locking block 42 extends outward relative to the pin 4 is consistent with the length direction of the strip-shaped hole 5.

[0023] The assembly and locking process of the pallet is as follows:

[0024] First, place the support leg 3 between the panel 1 and the base plate 2, aligning the slots 5 on each component. Then, align the slotted end 42 of the pin 4 with the slot 5, ensuring that the outward extension direction of the slotted end 42 relative to the pin 4 is consistent with the length direction of the slot 5. This is the first state of the pin 4. In this state, the pin 4 can easily pass through the slots 5 of the panel 1, the support leg 3, and the base plate 2 sequentially from top to bottom (or from bottom to top).

[0025] After the strip-shaped locking block 42 has completely passed through the strip-shaped hole 5 in the base plate 2, rotate the pin 4, for example, by 90 degrees, so that the outward extension direction of the strip-shaped locking block 42 relative to the pin 4 is at an angle to the length direction of the strip-shaped hole 5, preferably 90 degrees. This is the second state of the pin 4. In this state, the strip-shaped locking block 42 can no longer pass through the strip-shaped hole 5, and the upper surface of the strip-shaped locking block 42 abuts against the lower surface of the lower edge of the strip-shaped hole 5 in the base plate 2, forming an axial limiting fit of the pin 4. At the same time, since the radial dimension of the limiting block 41 is larger than the diameter of all the strip-shaped holes 5, it is restricted to the top of the panel 1. In this way, the panel 1, the support leg 3, and the base plate 2 are firmly clamped between the limiting block 41 and the strip-shaped locking block 42, achieving a quick and reliable connection.

[0026] The pallet assembly process requires only three simple steps: manually aligning the holes, inserting, and rotating pin 4. No specialized tools such as wrenches, screwdrivers, or hammers are needed, significantly reducing the operational threshold and tooling costs. The pin 4's transition between its first and second states is rapid, and a single rotation locks a single connection point. Compared to traditional bolt tightening or snap-fit ​​methods, assembly speed is increased several times, making it particularly suitable for logistics scenarios requiring frequent disassembly and rapid deployment. If a component, such as leg 3 or pin 4, is damaged, the damaged part can be quickly replaced by reversing the process, without scrapping the entire pallet. This modular repair capability greatly extends the overall product lifecycle, aligning with green environmental protection and sustainable development principles.

[0027] Furthermore, both the slot 5 in the panel 1 and the slot 5 in the base plate 2 are countersunk. This provides space for the limiting block 41, making the pallet surface flatter. Additionally, at least one groove 11 is provided around the top surface of the countersunk hole in the panel 1, and a protrusion 411, matching the shape of the groove 11, is provided on the bottom surface of the limiting block 41. When the pin 4 rotates from the first state to the second state, the protrusion 411 engages with the groove 11. The engagement of the protrusion and groove 11 provides a clear tactile feedback, allowing the user to intuitively confirm that the locking is complete. Furthermore, the engagement of the protrusion 411 and the groove 11 forms an effective anti-rotation mechanism, preventing the pin 4 from automatically rotating back to the first state when subjected to vibration or accidental impact, greatly enhancing the reliability and safety of the connection.

[0028] Furthermore, to optimize the fit between the strip-shaped locking block 42 and the strip-shaped hole 5, two strip-shaped locking blocks 42 are preferably arranged symmetrically on both sides of the end of the pin 4. Correspondingly, the strip-shaped hole 5 is composed of an arc-shaped hole 51 and two irregularly shaped holes 52 communicating with it. The diameter of the arc-shaped hole 51 is slightly larger than the diameter of the pin 4 shaft, used to guide the pin 4 through. The shape of the irregularly shaped hole 52 is adapted to the shape of the strip-shaped locking block 42, providing a clear passage path and a final limiting support surface for the strip-shaped locking block 42.

[0029] To enhance the overall structural strength and stability of the pallet, the support leg 3 consists of a support plate 31 and an internally fixed support column 32. Both ends of the support column 32 protrude from the corresponding surfaces of the support plate 31, and the support column 32 has a strip-shaped hole 5 formed along its axial direction. Additionally, grooves matching the shape of the ends of the support column 32 are machined on the side of the panel 1 facing the support leg 3 and the side of the base plate 2 facing the support leg 3, respectively. As the core load-bearing component, the support column 32 precisely engages with the panel 1 and the base plate 2 through the grooves, forming a stable mortise and tenon joint structure. This design directly transmits vertical pressure through the support column 32, avoiding stress concentration on the thinner support plate 31, significantly improving the pallet's load-bearing capacity and impact resistance, and extending its service life.

[0030] To further enhance the aesthetics and safety of the pallet bottom, a cover 6 is detachably installed on the bottom surface of the base plate 2. A through hole 21, matching the shape of the cover 6, is provided on the base plate 2, and this through hole 21 communicates with the strip-shaped hole 5. When the pin 4 is in the second state, installing the cover 6 can cover the through hole 21 and the internal strip-shaped locking block 42. This not only prevents dust and debris from entering the connecting mechanism, ensuring its long-term effective operation, but also prevents the strip-shaped locking block 42 from scratching the conveyor belt, forklift wheels, and other equipment, while also making the bottom of the pallet flat and aesthetically pleasing. To achieve quick installation and fixation of the cover 6, limiting protrusions 61 are provided on both sides of the cover 6, and limiting grooves 22, matching the limiting protrusions 61, are provided on the sidewall of the through hole 21. The bottom surface of the cover 6 is provided with an anti-slip surface 62. This anti-slip surface 62 can be achieved by knurling, setting raised dots, or a rubber coating. The anti-slip surface 62 effectively increases the friction between the pallet and the placement surface, such as the ground, shelves, or another pallet, preventing the pallet from sliding during storage, stacking, or transportation, and improving operational safety.

[0031] Furthermore, the number of legs 3 is multiple, and they are arranged in a rectangular array between the panel 1 and the base plate 2 according to the size of the pallet and the load-bearing requirements. The array distribution of multiple legs 3 provides uniform and stable support for the pallet, ensuring that the pallet will not bend or deform when subjected to heavy loads, and meeting the strength and rigidity requirements under different application scenarios.
