Description

A combination pallet Technical Field

[0001] This invention belongs to the field of pallets, and specifically relates to a modular pallet. Background Technology

[0002] A pallet is a logistics unit used in conjunction with forklifts, racks, and other logistics equipment, and it is widely used in logistics and other fields. Plastic pallets are currently the most commonly used type of pallet. Depending on the usage scenario, existing plastic pallets are generally divided into four types: zigzag pallets, grid pallets, single-sided pallets, and double-sided pallets. Each type of pallet is further divided into smooth pallets and grid pallets based on whether the surface is smooth or mesh, resulting in eight different types of pallets currently available.

[0003] Currently, plastic pallets are all manufactured using injection molding. Injection molds are related to the type and size of the pallet; a mold of a certain size and structure can only produce pallets of one size and type. Furthermore, the larger the pallet, the significantly higher the cost of the required mold (for example, when the pallet size increases by 20%, the mold cost typically increases by about 80%). Existing plastic pallets are usually molded in one piece. To meet the needs of different customers, manufacturers need to purchase large molds corresponding to the eight types of pallets mentioned above (at least molds for producing 1m×1.2m pallets or larger), resulting in high costs. Moreover, when the pallet size required by a customer changes, the manufacturer also needs to purchase additional large molds of the corresponding size, further increasing costs. Therefore, for pallet manufacturers, how to meet customer needs for different sizes or types of pallets at a lower cost and in a better manner is an urgent problem to be solved.

[0004] Summary of the Invention

[0005] The first aspect of this invention addresses the aforementioned technical problems by providing a modular pallet, which not only allows for the acquisition of different types of pallets at a lower cost but also facilitates the acquisition of pallets of different sizes at a lower cost. The main concept is as follows:

[0006] A combined pallet includes a carrying module and a support leg module. The carrying module and the support leg module are connected in an up-and-down mating manner. Among them, the carrying module includes a supporting component with a rectangular structure. The top of the supporting component is constructed with a working surface for placing goods, and the bottom of the supporting component is constructed with a plurality of connecting parts. The top of the support leg module is provided with mating parts adapted to the connecting parts. The support leg module includes a channel-shaped support leg mold, a grid-shaped support leg module, a single-sided support leg module, and a double-sided support leg module. The support leg module is connected to the supporting component through the mating of the mating parts and the connecting parts, so that the supporting component and the support leg module are combined into different types of pallets, and the support leg module is used to support the supporting component. In this solution, by configuring the combined pallet to include a carrying module and a support leg module, and the carrying module and the support leg module can be connected in an up-and-down mating manner, not only can the carrying performance be ensured, but also the carrying module and the support leg module constituting the pallet can be manufactured separately, and the volume of the carrying module and the support leg module is greatly reduced, so that the cost of the required molds is greatly reduced. By configuring a plurality of connecting parts at the bottom of the carrying module and providing mating parts adapted to the connecting parts at the top of the support leg module, the support leg module can be connected to the supporting component through the mating of the mating parts and the connecting parts to form a combined pallet. At the same time, the support leg module is configured to include four types: a channel-shaped support leg mold, a grid-shaped support leg module, a single-sided support leg module, and a double-sided support leg module. On the one hand, different types of pallets can be obtained very conveniently and efficiently by installing different types of support leg modules on the carrying module. On the other hand, the volume of the support leg module is greatly reduced compared with the overall volume of the pallet, so that the mold cost of the support leg module required for production is greatly reduced, and different types of pallets can be obtained at a lower cost. In addition, this combination method can greatly reduce the manufacturing and forming difficulty of the smooth pallet, thus further reducing the cost. When in use, this combined pallet can be used as a basic pallet with a fixed size, and pallets of other sizes can be obtained by combining side strips of different sizes on the side of this basic pallet, which is beneficial to obtaining pallets of different sizes at a lower cost and meeting the needs of different customers.

[0007] To solve the problem of preventing water from entering between the connecting part and the mating part, preferably, the connecting part includes a connecting column protruding downward in a direction away from the working surface, and a connecting groove formed in the connecting column. The connecting groove penetrates the lower end of the connecting column. The mating part includes a mating protrusion adapted to the connecting groove. During assembly, the support leg module and the carrying module are sleeved and connected by inserting the top of the mating protrusion into the connecting groove of the corresponding mating part. It can not only achieve more stable connection and improve the carrying capacity, but also cover the mating protrusion with the connecting column, effectively preventing rainwater from the outside from entering the inside of the pallet through the gap between the connecting part and the mating part, making the pallet cleaner, especially suitable for occasions with higher requirements such as food.

[0008] To improve stability and versatility, further, the supporting component includes nine connecting parts, which are arranged in a 3×3 array. The spacing between adjacent connecting parts is used to form an opening on the side of the combined pallet or adapt to the forklift openings of a forklift. This can not only improve the bearing capacity of the combined pallet, but also enable the foot module to achieve stable support at different positions of the supporting component, avoiding problems such as the goods falling or being damaged due to uneven stress on the supporting component; moreover, it can ensure a closer connection between the foot module and the supporting component and significantly improve versatility, so as to obtain different types of pallets by cooperating with different foot modules.

[0009] To solve the problem of obtaining a channel-shaped combined pallet at a low cost, preferably, the channel-shaped foot module includes three linear foot components. Three mating parts are respectively arranged at the tops of the linear foot components. The linear foot components are fixed to the bottom of the supporting component through the cooperation of the three mating parts with the three connecting parts. Thus, a channel-shaped combined pallet can be obtained at a low cost through the cooperation of the supporting component and the three linear foot components.

[0010] To solve the problem of obtaining a grid-shaped combined pallet at a low cost, preferably, the grid-shaped foot module includes a grid-shaped foot component. Nine mating parts are arranged at the top of the grid-shaped foot component. The nine mating parts respectively adapt to the nine connecting parts on the supporting component. The grid-shaped foot component is fixed to the bottom of the supporting component through the cooperation of the nine mating parts with the nine connecting parts. Thus, a grid-shaped combined pallet can be obtained at a low cost through the cooperation of the supporting component and the grid-shaped foot module.

[0011] To solve the problem of obtaining a single-sided combined pallet at a low cost, preferably, the single-sided foot module includes nine block-shaped foot components. Mating parts are arranged at the tops of the block-shaped foot components. Each block-shaped foot component is fixed to the bottom of the supporting component through the cooperation of the mating part with the connecting part. Thus, a single-sided combined pallet can be obtained at a low cost through the cooperation of the supporting component and the single-sided foot module, and the bearing performance and stability can be improved.

[0012] To solve the problem of obtaining a double-sided combined pallet at a low cost, preferably, the double-sided foot module includes a rectangular planar foot component. The bottom of the planar foot component is a plane. Nine mating parts arranged in an array are arranged at the top of the planar foot component. The nine mating parts respectively adapt to the nine connecting parts on the supporting component. The planar foot component is fixed to the bottom of the supporting component through the cooperation of the nine mating parts with the nine connecting parts. Thus, a double-sided combined pallet can be obtained at a low cost through the cooperation of the supporting component and the double-sided foot module.

[0013] A second aspect of this invention addresses the problem of pallets easily slipping off shelves and causing accidents when used in cold storage. Furthermore, the support module is equipped with an anti-slip component to limit the sliding of the support module relative to the shelf. The anti-slip component includes an anti-slip pin, which is retractably mounted on the support module. When the combined pallet is suspended, the anti-slip pin automatically extends from the bottom of the support module under the influence of gravity. When the combined pallet is placed on the ground or platform, the anti-slip pin automatically retracts into the support module. In this solution, by configuring anti-slip components on the support module, the anti-slip components can effectively prevent the support module from sliding relative to the shelf, effectively solving the problem of pallets easily slipping off the shelf when used in cold storage. By configuring the anti-slip components to include anti-slip pins, and the anti-slip pins being retractable and set in the support module, they can automatically extend from the bottom of the support module when the pallet is suspended in the air and lock onto the shelf to prevent the pallet from slipping off the shelf. They can also automatically retract into the support module when the pallet is placed on the ground or platform. The entire process requires no manual operation and does not affect the normal use of the pallet, which is very ingenious.

[0014] Furthermore, the mating protrusion has a limiting groove, the upper end of which penetrates the top of the mating protrusion. The anti-slip component is disposed within the limiting groove, and the bottom of the limiting groove has a connecting port that penetrates the bottom of the support leg module. The anti-slip pin corresponds to the connecting port and can extend out of the bottom of the support leg module through the connecting port. By placing the anti-slip component within the limiting groove, the assembly of the anti-slip component can be easily completed during pallet assembly, which is very convenient and efficient. The connecting port is configured to solve the problem of the anti-slip pin being able to extend and retract within the support leg module.

[0015] Preferably, the anti-slip pin includes an anti-slip end and a mounting end. The anti-slip end is constructed as a straight rod, with its outer diameter smaller than the inner diameter of the connection port. The mounting end is used to engage with the connection port, preventing the anti-slip pin from dislodging. This not only effectively solves the problem of anti-slip pins easily falling off, but also increases the overall weight of the anti-slip pin by utilizing the mounting end, allowing it to better extend from the bottom of the support module under gravity, thus preventing slippage.

[0016] Preferably, the anti-slip pin includes two parallel anti-slip ends connected to the same mounting end, making the anti-slip pin n-shaped. The bottom of the limiting groove has two connection ports, into which the two anti-slip ends are respectively inserted. This not only allows the two connection ports to constrain the anti-slip pin, ensuring it remains vertical, but also allows for a clearance fit between the connection ports and the anti-slip pin, enabling the anti-slip pin to automatically extend and retract.

[0017] To further improve the reliability of the anti-slip pin, a limiting part is also constructed within the limiting groove. This limiting part includes a limiting notch with an open top. When the mating protrusion is inserted into the connecting groove, the upper end of the limiting notch corresponds to the inner wall of the connecting groove, and the mounting end of the anti-slip pin is located within the limiting notch, forming a limiting fit with it. This allows the length of the anti-slip end extending beyond the bottom of the support leg module to be controlled via the limiting notch. This notch not only prevents slippage but also keeps the anti-slip pin within the range of the limiting notch, ensuring it will not dislodge from the connecting port even if the tray flips over, thus improving reliability.

[0018] To address the issue of anti-slip pins easily getting stuck during use, a guide channel is further constructed inside the limiting groove. This guide channel is connected to the connection port and is coaxial, allowing the anti-slip end of the anti-slip pin to be movably accommodated within it. By configuring the guide channel, a longer clearance fit is achieved between the guide channel and the anti-slip end, ensuring that the anti-slip pin's position does not shift, thus effectively preventing it from getting stuck.

[0019] The third aspect of this invention addresses the problem that when pallets are used in cold storage, ice easily forms between the anti-slip pins and the guide pipes, preventing the anti-slip pins from extending automatically and causing them to fail. Furthermore, the bottom of the support module is provided with a recessed waterproof groove corresponding to the limiting groove, and the waterproof groove and the limiting groove are connected through a connection port. The guide pipe is located at the top of the waterproof groove. This positions the guide pipe and the anti-slip pin at a higher position. On the one hand, this prevents external water from entering the guide pipe during use; on the other hand, even if the lower end of the anti-slip pin gets wet, the wet part of the anti-slip pin will not move to the guide pipe, thus ensuring that the guide pipe and the mating anti-slip pin remain dry, preventing ice formation in the cold storage and allowing the anti-slip pin to reliably perform its anti-slip function.

[0020] A fourth aspect of this invention addresses the problem of preventing water from the ground from wetting the guide pipe. Furthermore, the outer ring of the waterproof groove is equipped with a waterproof recess, and a waterproof ring is installed within the waterproof recess. When the tray is placed on the ground, the waterproof ring serves both as an anti-slip device and as a seal under pressure, effectively preventing external rainwater from entering the waterproof groove.

[0021] A fifth aspect of this invention addresses the problem of improving the load-bearing capacity of the modular pallet and preventing localized collapse. Furthermore, a support assembly is provided between the leg module and the load-bearing module. This support assembly includes vertically arranged support members, which enhance the load-bearing capacity at the side openings of the modular pallet. This prevents the pallet from collapsing due to localized overload when heavy objects are placed on it.

[0022] To address the issue of facilitating the assembly of the support components, the support assembly further includes mounting grooves for adapting the support components. The bottom of the supporting component has the mounting groove, located between the two connecting parts. The top of the leg module also has the mounting groove, located between the two mating parts. The mounting grooves of the supporting component and the leg module correspond vertically, with the upper and lower ends of the support component inserted into the mounting grooves at the bottom of the supporting component and the top of the leg module, respectively. This allows the support component to be vertically installed between the supporting component and the leg module during assembly, which is very simple, convenient, and efficient.

[0023] To further improve the anti-tipping ability and installation efficiency of the support, a reinforcing rib is also provided inside the mounting groove. When the end of the support is inserted into the mounting groove, the reinforcing rib abuts against one side of the support. The height of the reinforcing rib is lower than the height of the mounting groove, and the top of the reinforcing rib is chamfered or rounded to guide the support to slide into the mounting groove.

[0024] The sixth aspect of this invention addresses the problem of improving stress distribution to enhance service life and stability. Further, the mounting groove sidewall at the top of the support member is provided with an insertion hole, which connects the inner and outer sides of the mounting groove. The support assembly also includes an adjusting block, the upper surface of which is inclined, and the bottom surface of the support member is also machined as an inclined surface, with the inclination angle being the same as the inclination angle of the upper surface of the adjusting block. The adjusting block passes through the insertion hole, and its upper surface abuts against the bottom surface of the support member. A notch is provided at the bottom of the reinforcing rib, allowing the end of the adjusting block to slide into the notch. A baffle is also provided on the outer side of the mounting groove, directly opposite the insertion hole. A screw hole is provided on the baffle, its axial direction directly facing the adjusting block. The screw hole is threadedly connected to an adjusting screw, the front end of which abuts against the adjusting block. Rotating the adjusting screw pushes the adjusting block to move horizontally.

[0025] To address the issue of adjusting the height of the support component based on actual conditions during later use, the side of the adjusting block is further constructed with a bearing hole, and the outer side of the bearing hole has at least two threaded holes. It also includes a cover plate adapted to the bearing hole, the cover plate having a through hole adapted to the threaded hole. A bearing is installed at the end of the adjusting screw via an interference fit, the bearing is located within the bearing hole, and the cover plate constrains the bearing within the bearing hole. The cover plate is installed on the adjusting block via fasteners adapted to the threaded hole, allowing the adjusting screw to rotate relative to the adjusting block.

[0026] The seventh aspect of the present invention aims to solve the problem of obtaining trays of different sizes at low cost. Further, plug slots are respectively formed on the four side surfaces of the supporting member, and first locking holes corresponding to the plug slots are formed on the top of the supporting member; plug slots are also formed on the side surface of the leg member, and first locking holes corresponding to the plug slots are formed on the bottom of the leg member; an edge strip and a corner piece are further included. Two upper and lower rows of pins adapted to the plug slots are provided on one side of the edge strip, and second locking holes adapted to the first locking holes are formed on the pins; a slot and a third locking hole communicated with the slot are formed at the end of the edge strip; the corner piece is constructed as a square structure, and plugs adapted to the slot are respectively provided on two adjacent side surfaces of the corner piece, and fourth locking holes adapted to the third locking holes are formed on the plugs; the edge strip is arranged on the four sides of the supporting member and is simultaneously connected to the supporting member and the leg member through fasteners; the corner piece is arranged at the corners of the supporting member and is fixed to the edge strip or an adjacent corner piece through fasteners. This solution can change the size of the entire tray by adding an edge strip, so as to obtain trays of different sizes. The required molds are small in volume and small in quantity, which can not only significantly reduce costs, but also obtain trays of different sizes, which is very simple and efficient.

[0027] Compared with the prior art, the combined tray provided by the present invention can obtain different types of trays through combination, which is very convenient and efficient. It can not only greatly reduce the costs of tray manufacturers, but also facilitate obtaining trays of different sizes at lower costs, meet the needs of different customers, and better meet the market demand.

Detailed Implementation

[0054] Example 1

[0055] As shown in Figure 1, this embodiment provides a load-bearing module 1 suitable for modular pallets, which can be adapted to different types of support modules 2, thereby forming different types of modular pallets according to the different types of support modules 2, such as: a three-line pallet, a grid pallet, a double-sided pallet, and a single-sided pallet.

[0056] In this embodiment, the supporting module 1 includes a supporting component, which has an overall rectangular structure, as shown in Figure 1. The supporting component is made of plastic and can be injection molded in one step. The top of the supporting component is a working surface, mainly used for placing goods. Depending on the application scenario, the working surface can be made into a flat surface (as shown in Figure 1) or a mesh surface. When the working surface is a mesh surface, the friction between the mesh surface and the goods increases, which helps prevent the goods from sliding.

[0057] As shown in Figure 1, a limiting plate 14 is provided at the edge of the working surface, which is integrally formed with the supporting component. The limiting plate 14 can restrain and limit the goods when there are goods on the supporting component, preventing the goods from sliding.

[0058] To enable the bottom of the supporting component to connect with different types of support leg modules 2, in this embodiment, the bottom of the supporting component is provided with multiple connecting parts, as shown in Figures 1 and 2. Each connecting part includes a connecting post 15 protruding downwards in the direction away from the working surface, and a connecting groove 12 constructed in the connecting post 15. The connecting groove 12 can be a rectangular groove, a circular groove, or a polygonal groove, etc., and extends through the lower end of the connecting post 15. This allows the top of the support leg module 2 to be inserted into the connecting groove 12 during assembly, enabling the supporting component and the support leg module 2 to fit together, forming a tray. Furthermore, the connecting groove 12 in this embodiment can accommodate different types of support leg modules 2. When different types of support leg modules 2 are connected to the connecting groove 12, the support leg module 2 and the supporting component combine to form different types of trays.

[0059] For example, when the connecting groove 12 is connected to the three-dimensional support leg module 2, the supporting component and the three-dimensional support leg module 2 combine to form a three-dimensional combined pallet, as shown in Figure 3. When the connecting groove 12 is connected to the four-dimensional support leg module 2, the supporting component and the four-dimensional support leg module 2 combine to form a four-dimensional combined pallet. When the connecting groove 12 is connected to the double-sided support leg module 2, the supporting component and the double-sided support leg module 2 combine to form a double-sided combined pallet. When the connecting groove 12 is connected to the single-sided support leg module 2, the supporting component and the single-sided support leg module 2 combine to form a single-sided combined pallet.

[0060] It is understandable that since the supporting component can be connected to different types of leg modules 2, different types of combined pallets can be obtained by connecting the supporting component to different types of leg modules 2. Therefore, in this case, on the one hand, different types of pallets can be obtained by installing different types of leg modules 2 on the supporting module, which is very convenient and efficient; on the other hand, using this method, the volume of the supporting module is greatly reduced compared to the existing integral pallets, thereby greatly reducing the mold cost. At the same time, the volume of each leg module 2 is also greatly reduced compared to the integral pallet, which reduces the difficulty of mold design and manufacturing, further reducing the mold cost, and thus allowing different types of pallets to be obtained at a lower cost.

[0061] In addition, since different types of support modules 2 can be combined to form different types of pallets, manufacturers can stock the support components in advance and then purchase or manufacture the corresponding support modules 2 as needed according to customer requirements. Pre-manufacturing the support components improves production efficiency.

[0062] In implementation, the number and arrangement of the connecting parts in the supporting component can be determined according to actual needs. During implementation, there is a gap between adjacent connecting posts 15, and the connecting posts 15 are arranged in an array, as shown in Figures 1 and 2. This not only allows the use of the gap to form openings 17 or forklift bays 16 for adapting to forklifts, but also better adapts to various types of support modules, enabling the acquisition of different types of pallets at low cost. For example, as shown in Figure 2, there are nine connecting posts 15 (including connecting grooves 12) at the bottom of the supporting component, arranged in an array. The nine connecting grooves 12 are arranged in a 3×3 array. The gap between adjacent connecting posts 15 is used to form openings 17 or forklift bays 16 on the side of the modular pallet, as shown in Figures 1 and 3. Simultaneously, the connecting grooves 12 (connecting posts 15) located on the outer side are positioned at the edge of the supporting component, as shown in Figure 1, ensuring that the edge of the supporting component is also supported.

[0063] By configuring nine connecting slots 12 (connecting posts 15), the three-dimensional support modules 2, the grid-shaped support modules 2, the double-sided support modules 2, and the single-sided support modules 2 can all be stably installed at the bottom of the supporting component, and the connection between the supporting component and the support modules 2 is tighter, preventing the supporting component from detaching from the support modules 2. Simultaneously, the nine connecting posts 15 arranged in an array ensure that different positions at the bottom of the supporting component are supported, making the goods placed on top of the supporting component more stable. It should be noted that in some other embodiments, the connecting part can also be other structures. For example, the connecting part can be a connecting bolt, which passes through the supporting component, and the support module 2 is provided with a threaded hole. By screwing the connecting bolt into the threaded hole, the connection between the supporting component and the support module 2 can be achieved.

[0064] Example 2

[0065] This embodiment provides a modular pallet, as shown in Figure 3, including a support module 2 and a load-bearing module 1 from Embodiment 1. In this embodiment, the support module 2 and the load-bearing module 1 are connected vertically to form a pallet. The load-bearing module 1 can be adapted to at least two different types of support modules 2, thereby forming different types of pallets depending on the different support modules 2. For example, the support module 2 may include a three-dimensional support module 2, a four-dimensional support module 2, a double-sided support module 2, and a single-sided support module 2. Each type of support module 2 has a mating part 2021 at its top, allowing the support module to be connected to the supporting component through the mating part 20 and the connecting part, thereby allowing the supporting component and the support module to be combined to form different types of pallets.

[0066] In this embodiment, the tandem-shaped support module 2 includes three straight support components 25, as shown in Figures 4 and 5. Each straight support component 25 has a mating portion 2021 at its top. The mating portion 2021 is a mating protrusion, which can be rectangular, circular, or polygonal. Its shape matches the connecting groove 12, and its size is slightly smaller than the connecting groove 12. The top of the mating protrusion can be embedded into the connecting groove 12, allowing the mating protrusion and the connecting groove 12 to fit together. When the mating protrusion and the connecting groove 12 are fitted together, the supporting component and the straight support component 25 are connected together. To ensure that the mating protrusions on the top of the straight support component 25 can fit into the arrayed connecting grooves 12, each straight support component 25 in this embodiment has three mating protrusions at its top, as shown in Figures 4 and 5. The three mating protrusions are respectively located at both ends and the middle of the straight support component 25. The three mating protrusions can simultaneously engage with the three connecting grooves 12 located at the bottom of the support component, making the connection between the support component and the straight leg component 25 tighter. When the three straight leg components 25 are installed in parallel at the bottom of the support component, the three straight leg components 25 and the support component combine to form a three-dimensional combined pallet.

[0067] In this embodiment, the grid-shaped support module 2 includes a grid-shaped support component, as shown in Figure 6. The top of the grid-shaped support component has nine mating protrusions arranged in an array, allowing each of the nine protrusions to correspond one-to-one with one of the nine connecting slots 12. When the mating protrusions on the top of the grid-shaped support component are connected one-to-one with the connecting slots 12 located at the bottom of the support component, the grid-shaped support component and the support component combine to form a grid-shaped combined tray.

[0068] In this embodiment, the double-sided support module 2 includes a rectangular faceted support component 28, as shown in Figure 7. The bottom of the faceted support component 28 is flat, and the top of the faceted support component 28 is provided with nine mating protrusions arranged in an array. The nine mating protrusions correspond one-to-one with nine connecting grooves 12. When the mating protrusions on the top of the faceted support component 28 are connected one-to-one with the connecting grooves 12 located at the bottom of the support component, the faceted support component 28 and the support component are combined to form a double-sided combined tray.

[0069] In this embodiment, the single-sided support module 2 includes at least four independent block-shaped support components 27. Each block-shaped support component 27 is rectangular in shape, as shown in Figure 8. A mating protrusion is provided on the top of each block-shaped support component 27. After the mating protrusion is embedded into the connecting groove 12 at the bottom of the supporting component, the block-shaped support component 27 is stably connected to the supporting component. In practice, the number of block-shaped support components 27 can be four to nine. Each block-shaped support component 27 is fixed to the bottom of the supporting component through the mating part 20 and the connecting part.

[0070] In this embodiment, the connecting groove 12 and the mating protrusion can be fixedly connected by a locking structure. The locking structure includes a limiting protrusion 22 and a limiting opening 13, as shown in Figures 1, 4, 9, and 13. The limiting protrusion 22 is disposed on the outer surface of the mating protrusion, and the limiting protrusion 22 can be a circular protrusion, a polygonal protrusion, or a rectangular protrusion, etc. At the same time, a through limiting opening 13 is constructed on the side wall of each connecting groove 12. The limiting opening 13 can also be a circular opening, a polygonal opening, or a rectangular opening, etc., and the limiting opening 13 is used to correspond to the limiting protrusion 22. Both the limiting protrusion 22 and the limiting opening 13 can be configured to be at least two, and are located on different sides of the mating protrusion and the connecting groove 12, respectively, so that the connection between the bearing module 1 and the support module 2 is more stable.

[0071] During assembly, when the mating protrusion is inserted into the connecting groove 12, the limiting protrusion 22 located on the side of the mating protrusion can be inserted into the limiting port 13. The mutual limiting of the limiting protrusion 22 and the limiting port 13 stabilizes the load-bearing module 1 and the support module 2. As shown in Figure 9, the top of the limiting protrusion 22 can be set as an inclined surface, allowing the connecting groove 12 to deform appropriately. This solves the problem of the limiting protrusion 22 getting stuck, ensuring that the mating protrusion can be smoothly inserted into the connecting groove 12.

[0072] Example 3

[0073] This embodiment further optimizes and improves upon embodiment 2, as shown in Figures 10 and 11. When pallets are used in cold storage, to accommodate more goods, pallets carrying goods are usually placed on shelves (usually made of metal) inside the cold storage. The shelves have multiple layers, each capable of accommodating pallets carrying goods. In low-temperature environments, ice and frost form on the surface of the pallets, making them very easy to fall off the shelves. To solve this problem, in the modular pallet provided in this embodiment, the support module 2 is also equipped with an anti-slip component 3 to limit the sliding of the support module relative to the shelf. Correspondingly, a limiting groove is constructed inside the protrusion, with the upper end of the limiting groove penetrating through the top of the protrusion, as shown in Figure 10. The inside of the limiting groove is hollow (of course, hollow does not mean that reinforcing ribs 43 and other related structures cannot be set inside the limiting groove).

[0074] An anti-slip component 3 is installed inside the limiting groove, as shown in Figure 10. The anti-slip component 3 includes anti-slip pins 31, and the number of anti-slip pins 31 can be adjusted according to different support leg modules 2. For example, when the support leg module 2 is a three-dimensional support leg module 2, two anti-slip pins 31 can be installed on each straight support leg component 25, and the two anti-slip pins 31 are respectively set at the bottom ends of the straight support leg component 25. When the support leg module 2 is a four-dimensional support leg module 2, six anti-slip pins 31 can also be set, and the six anti-slip pins 31 are arranged in an array on the bottom of the four-dimensional support leg component. That is, the anti-slip component 3 can be set on straight support leg component 25, four-dimensional support leg component 26, block support leg component 27, and surface support leg component 28.

[0075] In implementation, the anti-slip pin 31 is retractably installed inside the limiting groove. The anti-slip pin 31 includes an anti-slip end 31a and an installation end 31b. When the pallet is placed on the ground, the anti-slip end 31a of the anti-slip pin 31 is pressed against the ground and retracts into the mating protrusion. When the pallet is placed on a shelf, the pallet is suspended in the air, and the anti-slip pin 31 can automatically extend from the bottom of the support module 2 under the action of gravity. The anti-slip end 31a of the anti-slip pin 31 presses against the shelf, preventing the pallet from falling off the shelf, thus effectively solving the problem of pallets easily slipping off the shelf when used in cold storage.

[0076] In implementation, the bottom of the limiting groove is constructed with a connection port 29, which penetrates the bottom of the support module. The anti-slip end 31a of the anti-slip pin 31 corresponds to the connection port 29 and can extend out of the bottom of the support module through the connection port 29, as shown in Figure 10.

[0077] The anti-slip component 3 can be implemented in various ways. For example, the anti-slip pin 31 may include an anti-slip end 31a, which is constructed as a straight rod. The outer diameter of the anti-slip end 31a is smaller than the outer diameter of the connecting port 29. The mounting end 31b is used to lock into the connecting port 29 to prevent the anti-slip pin 31 from coming out of the connecting port 29. Alternatively, as shown in Figure 10, the anti-slip pin 31 may include two anti-slip ends 31a, which are parallel to each other and connected to the same mounting end 31b, making the anti-slip pin n-shaped. Correspondingly, as shown in Figure 10, the bottom of the limiting groove has two connecting ports 29, and the two anti-slip ends 31a are respectively inserted into the two connecting ports 29.

[0078] Furthermore, a limiting part 32 is constructed within the limiting groove. Specifically, the limiting part 32 includes a limiting notch 35 with an open top, as shown in Figure 10. The mounting end 31b of the n-shaped anti-slip pin 31 is accommodated in the limiting notch 35. When the mating protrusion is inserted into the connecting groove, the upper end of the limiting notch 35 abuts against the inner wall of the connecting groove, as shown in Figure 10. The mounting end 31b of the anti-slip pin 31 is located within the limiting notch 35 and forms a limiting fit with the limiting notch 35. This allows the length of the anti-slip end 31a extending beyond the bottom of the support module 2 to be controlled via the limiting notch 35. For example, when the anti-slip end 31a of the anti-slip pin 31 extends due to gravity, the mounting end 31b of the anti-slip pin 31 can contact the inner wall of the limiting notch 35. The mounting end 31b of the anti-slip pin 31 and the inner wall of the limiting notch 35 mutually limit each other, preventing the anti-slip pin 31 from extending further out of the support module 2. When the pallet is placed on the ground, the anti-slip end 31a of the anti-slip pin 31 retracts into the support leg module 2, preventing damage to the ground. The length of the limiting notch 35 is less than the length of the mounting end 31b, ensuring that the mounting end 31b will not come out of the connection port 29 even if the pallet is flipped.

[0079] More specifically, the limiting part 32 also includes a vertical plate 34 (reinforcing rib) constructed within the limiting groove, and a limiting notch 35 constructed at the top of the vertical plate 34, as shown in Figure 10. When the mating protrusion is inserted into the connecting groove, the top of the vertical plate 34 abuts against the inner wall of the connecting groove, as shown in Figure 10. Since the top of the limiting notch 35 is open before assembly, when it is necessary to install the anti-slip pin 31 inside the support module 2, the anti-slip end 31a of the anti-slip pin 31 can be inserted into the connecting port 29, while the mounting end 31b of the anti-slip pin 31 is directly placed inside the limiting notch 35, making installation more convenient.

[0080] When the tray is placed on the ground, in order to prevent the bottom of the anti-slip pin 31 from rubbing against the ground and to prevent damage to the ground or the anti-slip pin 31, the bottom of the anti-slip end 31a is also constructed with ball bearings 31c, as shown in Figure 11.

[0081] Furthermore, a guide pipe 33 is constructed inside the limiting groove. The guide pipe 33 is connected to the connection port 29 and is coaxial, as shown in Figure 10. The anti-slip end 31a of the anti-slip pin 31 can be accommodated in the guide pipe 33 to achieve the guiding function of the anti-slip pin 31 and solve the problem that the anti-slip pin 31 will deviate and get stuck when it performs telescopic movement.

[0082] When a pallet is placed on a shelf, the anti-slip pin 31 extends due to gravity and engages with the shelf for restraint. Therefore, after prolonged use, or when the goods are heavy, the anti-slip pin 31 is easily deformed due to the force exerted on it. When deformed, the anti-slip pin 31 cannot retract into the pallet and remains extended and tilted. Obviously, when the anti-slip pin 31 cannot retract into the pallet, it will press against the ground, preventing the pallet from lying flat and affecting its normal use, and may also damage the ground. To solve this problem, the mounting end 31b and the anti-slip end 31a of the anti-slip pin 31 are detachably connected, as shown in Figure 11. When the anti-slip end 31a of the anti-slip pin 31 is tilted and deformed, it can be separated from the mounting end 31b, ensuring that the anti-slip pin 31 does not affect the normal operation of the pallet. In practice, the anti-slip end 31a and the mounting end 31b can be detachably connected by a threaded connection to ensure a stable connection between the anti-slip end 31a and the mounting end 31b.

[0083] In a further embodiment, as shown in Figure 12, the bottom of the support module 2 is also provided with a recessed waterproof groove 23. The waterproof groove 23 can be a circular groove or a rectangular groove. The waterproof groove 23 corresponds to the limiting groove, and the waterproof groove 23 and the limiting groove are connected through the connection port 29. The guide pipe 33 is located at the inner top of the waterproof groove 23, which can effectively solve the problem that when the pallet is used in the freezer, ice easily forms between the anti-slip pin and the guide pipe, causing the anti-slip pin to fail to extend automatically.

[0084] In a further embodiment, as shown in Figure 12, the outer ring of the waterproof groove 23 is also equipped with a waterproof recess. The waterproof recess is a circular groove. A waterproof ring 24 is glued inside the waterproof recess. The waterproof ring 24 can be a rubber ring. When the tray is placed on the ground, the waterproof ring 24 contacts the ground and deforms to form a seal. Therefore, when external water flows to the waterproof ring 24, the external water is blocked by the waterproof ring 24, and the external water cannot enter the interior of the waterproof groove 23, effectively preventing the guide pipe from getting wet and causing ice to form inside the freezer.

[0085] Furthermore, the anti-slip end 31a is also equipped with a locking mechanism, which includes a locking bolt 91, a transmission rod 92, a limiting pin 93, and a spring 94. The anti-slip end 31a has a channel 311 extending through its lower end, and the lower end of the channel 311 has an internal thread 312. The locking bolt 91 has an external thread 911 adapted to the internal thread 312, as shown in Figure 23. The transmission rod 92 is adapted to the channel 311, is disposed within the channel 311, and can move along the channel 311. The side of the anti-slip end 31a has a slide 313 communicating with the channel 311, as shown in Figure 25. The slide 313 is stepped. The limiting pin 93 is adapted to... The slide 313 is equipped with a limiting pin 93, which is located within the slide 313 and can move along the slide 313. The inner side of the limiting pin 93 is constructed as a first inclined surface 931, as shown in Figure 23. At the same time, the upper end of the transmission rod 92 is constructed with a second inclined surface 921 adapted to the first inclined surface 931. The spring 94 is located between the limiting pin 93 and the inner wall of the channel 311. When the limiting pin 93 moves outward, the elastic potential energy of the spring 94 increases. As shown in Figure 25, the locking bolt 91 is threaded to the lower end of the anti-slip end 31a. The lower end of the transmission rod 92 abuts against the locking bolt 91. Under the elastic force of the spring 94, the first inclined surface 931 and the second inclined surface 921 remain pressed together. When the anti-slip component 3 of this pallet is needed, tighten the locking bolt 91 to move it away from the anti-slip end 31a. Under the elastic force of the spring 94, the limiting pin 93 automatically moves towards the center of the anti-slip end 31a, causing the limiting pin 93 to retract into the slide rail 313, as shown in Figures 24 and 25. This unlocks the anti-slip end 31a, allowing it to fall automatically under gravity when the pallet is suspended, thus achieving the purpose of limiting and preventing slippage. When the anti-slip component 3 of this pallet is not needed, tighten the locking bolt 91 to move it closer to the anti-slip end 31a, causing the transmission rod 92 to rise. The transmission rod 92 overcomes the elastic force of the spring 94, driving the limiting pin 93 to extend outward from the anti-slip end 31a. This allows the limiting pin 93 to lock onto the upper end of the guide pipe 33, thus locking the anti-slip end 31a, as shown in Figure 23. This prevents the anti-slip end 31a from extending automatically when the pallet is suspended. This design allows the pallet to meet various usage scenarios, significantly improving its versatility. It also solves the problem that the anti-slip component 3 can easily interfere with the normal use of the pallet in situations where anti-slip is not required. In implementation, two symmetrically arranged slide rails 313 and two symmetrically arranged locking bolts 91 can be configured, as shown in Figure 25. The upper end of the transmission rod 92 has two symmetrically constructed first inclined surfaces 931, which facilitates more stable transmission.

[0086] Example 4

[0087] In embodiments 1-3, different types of modular pallets are obtained by combining the supporting components and the support leg modules. As mentioned above, the spacing between two adjacent connecting parts can form an opening 17 or a forklift opening 16 adapted to a forklift on the side of the modular pallet, as shown in Figure 3. For the zigzag, grid, and double-sided modular pallets, a forklift opening 16 is formed in one set of opposite sides, while a closed opening 17 is formed in another set of opposite sides, as shown in Figures 3 and 13. This opening 17 is formed by the upper and lower fitting of the supporting components and the support leg modules. To further improve the load-bearing capacity of this modular pallet, the main difference between this embodiment and the above embodiments is that this modular pallet also includes a support component 4. The support component 4 includes a support member 41 and a mounting groove 42 adapted to the support member 41. The support member 41 can be tubular or columnar and is made of metal, such as iron or steel. Support member 41 is disposed between the support leg module 2 and the load-bearing module 1 to enhance the load-bearing capacity at the opening 17 of the combined pallet, preventing local collapse due to excessive stress on the pallet. Furthermore, to ensure better support, at least two support members 41 can be installed within the opening 17 between the support leg module 2 and the load-bearing module 1, as shown in Figure 13, to guarantee a better support effect. In implementation, rectangular tubes are preferred for the support member 41 to further improve load-bearing capacity.

[0088] In implementation, the bottom of the supporting component 11 is provided with a mounting groove 42, which is located between the two connecting parts (connecting posts 15), as shown in Figures 13 and 14. Simultaneously, the top of the support module 2 (such as the straight support component 25, the grid-shaped support component 26, and the surface-shaped support component 28) is also provided with a mounting groove 42, which is located between the two mating parts 20 (matting protrusions), as shown in Figure 13. The mounting grooves 42 of the supporting component and the support module 2 are in a vertically corresponding relationship. Furthermore, the dimensions of the mounting grooves 42 are adapted to the end dimensions of the support member 41. The upper and lower ends of the support member 41 can be respectively inserted into the mounting grooves 42 at the bottom of the supporting component 11 and at the top of the support module 2, thus constraining and fixing the two ends of the support member 41, as shown in Figure 13. This keeps the support member 41 vertical and prevents it from tipping over.

[0089] Example 5

[0090] This embodiment is a further optimization and improvement based on embodiment 4. As shown in Figure 15, in this embodiment, a reinforcing rib 43 is also provided inside the mounting groove 42. When the end of the support member 41 is inserted into the mounting groove 42, the reinforcing rib 43 abuts against one side of the support member 41, improving the anti-tipping ability and ensuring that the support member 41 remains stable and vertical. The top of the reinforcing rib 43 is provided with a chamfer or rounded corner, as shown in Figure 15. The chamfer and rounded corner can guide the support member 41 to slide into the mounting groove 42, reducing the difficulty of inserting the support member 41 and improving the installation efficiency of the support member 41.

[0091] As shown in Figure 15, the height of the reinforcing rib 43 is lower than the height of the mounting groove 42, allowing the support member 41 to first abut against the side of the mounting groove 42 under the guidance of the chamfer or rounded corner, and then continue to contact the reinforcing rib 43. When the other sides of the support member 41 are in contact with the mounting groove 42, the side of the support member 41 fits against the side of the mounting groove 42, keeping the support member 41 in a vertical state. At this time, the support member 41 can smoothly slide down along the side of the mounting groove 42, allowing the support member 41 to slide into the space between the reinforcing rib 43 and the mounting groove 42, so that the reinforcing rib 43 abuts against the side of the support member 41, allowing the support member 41 to be quickly installed in place and stably maintain a vertical state.

[0092] Since the support component 11 and the foot module 2 are fitted together, the initial distance H between the upper and lower mounting slots 42 is determined. However, due to manufacturing tolerances, assembly errors, etc., the height of the support component 41 is often less than H, causing the top of the installed support component 41 to not abut against the upper support component 11, thus failing to achieve the function of bearing and reinforcement. To solve this problem, the side wall of the mounting slot 42 at the top of the foot component 2 is provided with an insertion hole 44, as shown in Figure 15. The insertion hole 44 connects the inner and outer sides of the mounting slot 42 and is used to insert a pad 45. The pad 45 is inserted into the bottom of the mounting slot 42 through the insertion hole 44, so as to eliminate the influence of manufacturing and assembly errors and ensure that the top of the support component 41 and the support component 11 always maintain mutual contact.

[0093] During implementation, the pad 45 can be hammered into the mounting groove 42 from the insertion hole 44, between the bottom of the mounting plate 42 and the bottom of the support member 41. Multiple pads 45 can be inserted as needed, and the stacked pads 45 abut against the bottom of the support member 41, as shown in Figure 15, to adjust the height of the support member 41. As shown in Figure 16, the insertion hole 44 corresponds to the reinforcing rib 43, which positions and limits the pad 45, preventing damage to the side wall of the mounting groove 42.

[0094] Example 6

[0095] In Example 5, inserting a pad 45 is used to eliminate the influence of errors. However, in practice, if the inserted pad 45 is too thick, the two ends of the support member 41 will be pressed tightly against the supporting member 11 and the foot module 2, resulting in significant stress within the support member 41 and greatly reducing its service life. If the inserted pad 45 is too thin, it will not achieve the purpose of the support member 41 abutting against the supporting member 11. This makes it difficult to accurately control the required thickness of the inserted pad 45 in actual operation, and it cannot be guaranteed that the upper end of the support member 41 is exactly abutting against the supporting member 11 and is essentially stress-free. To solve this problem, the support assembly 4 in this embodiment also includes an adjusting block 46, as shown in Figure 16. The upper surface of the adjusting block 46 is an inclined surface, and the bottom surface of the support member 41 is also machined as an inclined surface, with the same inclination angle as the upper surface of the adjusting block 46. The adjusting block 46 passes through the insertion hole 44, and the upper surface of the adjusting block 46 abuts against the bottom surface of the support member 41, as shown in Figure 16. In use, the height of the support member 41 can be adjusted by moving the horizontal adjustment block 46, achieving continuous and stepless adjustment to meet any height requirement. Furthermore, the support member 11 and the adjustment block 46 jointly bear the vertical load, with the support member 11 and adjustment block 46 in surface contact, resulting in greater load-bearing capacity and stability. As shown in Figure 16, a notch is provided at the bottom of the reinforcing rib 43, allowing the end of the adjustment block 46 to slide into the notch, solving the problem of the reinforcing rib 43 obstructing the movement of the adjustment block 46. During the lifting and lowering of the support member 11, the reinforcing rib 43 and the side wall of the mounting groove 42 act as guides, ensuring that the support member 11 is raised and lowered strictly vertically. Adjusting the height of the support member 41 by moving the horizontal adjustment block 46 allows for continuous and stepless height adjustment, which is beneficial for the upper end of the support member 41 to abut against the supporting component 11 after adjustment, and maintains a state of minimal pressure between the support member 41 and the supporting component 11.

[0096] In addition, by using the adjustment block 46 in conjunction with the support member 41, the contact area of ​​the support member 41 can be increased, and the force transmitted by the support member 41 can be applied to a larger range, thereby dispersing the force of the support member 41 and avoiding stress concentration.

[0097] In a further embodiment, a baffle 47 is provided on the outer side of the mounting groove 42, as shown in Figure 16. The baffle 47 is positioned directly opposite the insertion hole 44. A screw hole is provided on the baffle 47, with the axis of the screw hole aligned with the adjusting block 46. The screw hole is threadedly connected to an adjusting screw 48, as shown in Figure 16. The front end of the adjusting screw 48 can abut against the adjusting block 46. By rotating the adjusting screw 48, the adjusting block 46 can be moved horizontally. The horizontally moving adjusting block 46 can finely adjust the height of the support member 41, making adjustment not only more convenient but also more precise.

[0098] As the tray is used, the distance H between the upper and lower mounting slots 42 may change, causing the originally adjusted support 41 to be too high. Therefore, in a further solution, the side of the adjusting block 46 is constructed in the bearing hole 461, as shown in Figure 17. The outer side of the bearing hole 461 has at least two threaded holes and also includes a cover plate 49 adapted to the bearing hole 461. The cover plate 49 has a through hole adapted to the threaded hole. The end of the adjusting screw 48 is fitted with a bearing 7 through an interference fit. The bearing 7 is set in the bearing hole 461 and is constrained in the bearing hole 461 by the cover plate. The cover plate 49 is installed on the adjusting block 46 by a fastener 6 adapted to the threaded hole, so that the adjusting screw 48 can rotate relative to the adjusting block 46 and can drive the adjusting block 46 to horizontally insert into the insertion hole 44 and horizontally withdraw from the insertion hole 44. This allows for fine adjustment of the lowering of the support 41, and the height of the support 41 can be adjusted according to the actual situation during subsequent use, thereby improving the stress state and service life of the support 41.

[0099] Example 7

[0100] To address the issue of obtaining pallets of different sizes at low cost, based on the above embodiments, the combined pallet provided in this embodiment further includes side strips 5 and corner pieces 8. The four sides of the supporting component 11 are each constructed with a row of insertion slots 19, and the top of the supporting component 11 is constructed with first locking holes 18 corresponding to the insertion slots 19, as shown in Figures 18 and 19. The sides of the support components 2 (such as straight support components 25, grid-shaped support components 26, block-shaped support components 27, and surface-shaped support components 28) are also constructed with a row of insertion slots 19, and the bottom of the support components 2 is constructed with first locking holes 18 corresponding to the insertion slots 19.

[0101] As shown in Figures 18-20, the edge strip 5 is elongated, with two rows of pins 51 on one side that fit into the insertion slot 19. The pins 51 are elongated and have second locking holes 52 that fit into the first locking hole 18. The length of the edge strip 5 matches the side length of the supporting component 11. The end of the edge strip 5 has a slot 82 and a third locking hole 53 that communicates with the slot 82. The third locking hole 53 is located on the upper or lower surface of the edge strip 5.

[0102] As shown in Figures 18 and 22, the corner piece 8 is constructed as a block-shaped structure. Two adjacent sides of the corner piece 8 are respectively provided with plugs 81 that are adapted to the slot 82. The plugs 81 are constructed with a fourth lock hole 83 that is adapted to the third lock hole 53.

[0103] During assembly, the side strips 5 are positioned on the four sides of the supporting component 11 and are simultaneously connected to the supporting component 11 and the support leg component 2 via fasteners 6. This provides a more stable connection between the side strips and improves the overall load-bearing capacity of the modular pallet. Corner pieces 8 are positioned at the corners of the supporting component 11 and are fixed to the side strips 5 or adjacent corner pieces 8 via fasteners 6, as shown in Figures 18 or 21. The corner pieces 8 fill the space at the corners of the supporting component 11, allowing pallets of different sizes to be formed through the combination of the supporting component, the side strips, and the corner pieces 8. For specific corner piece 8 splicing and assembly techniques, refer to Chinese Patent CN113955275B, "A Modular Pallet." This assembly method significantly reduces the number and size of molds required, thereby greatly reducing costs and enabling the production of pallets of different sizes.

[0104] Furthermore, the other side of the edge strip 5 is also constructed with a plug groove 19 for the fitting of the pin and a corresponding first locking hole, so that the edge strips can be spliced ​​together with fasteners, as shown in Figure 21. Thus, one layer, two layers, three layers, etc., of edge strips can be combined on the outside of the supporting component 11 to obtain trays of different sizes. The other two adjacent sides of the corner piece 8 are respectively provided with a slot 82 for the fitting of the plug 81 and a third locking hole 53 communicating with the pin, so that the corner pieces can be spliced ​​together with fasteners, as shown in Figure 21.

[0105] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
