Description

Technical Field

[0001] This application relates to the field of cargo reinforcement technology, and in particular to a modular, reusable pallet cargo reinforcement device and method. Background Technology

[0002] Pallets, as the core carrier of modern logistics unitized operations, are widely used throughout the entire supply chain of production, warehousing, transshipment, and transportation. Goods stacked on pallets are susceptible to external impacts, center of gravity shifts, vibrations, and friction during forklift handling, pallet truck transfers, truck travel, and stacking, leading to problems such as interlayer slippage, overall tipping, and goods scattering. This constitutes a systemic risk source throughout the entire logistics chain.

[0003] Unreinforced palletized cargo can trigger a series of chain reactions: First, friction and collisions between cargo items can easily cause scratches and deformation of the outer packaging, resulting in irreversible damage to fragile items such as glass and ceramics, precision parts such as electronic components, and easily scratched parts such as painted metal and plastic. Second, loose cargo restricts stacking height, reduces warehouse space utilization, increases the caution required for loading, unloading, and storage operations, lowers overall operational efficiency, and significantly increases labor and time costs. Third, cargo tipping over can injure operators, damage forklifts and racking equipment, and scatter cargo can block aisles, increasing secondary handling costs and on-site safety risks. Fourth, loose or damaged cargo during transit and loading / unloading can easily lead to disputes over liability between the shipper, logistics provider, and consignee, resulting in additional processes and economic costs such as rework, replenishment, and insurance claims. Therefore, reliable, efficient, and economical reinforcement of palletized cargo is a necessary step to ensure logistics safety, improve operational efficiency, and control operating costs.

[0004] Currently, the industry mainly improves the overall integrity and transportation stability of pallet units through physical constraints or interface resistance enhancement. According to the technical complexity, implementation cost and applicable scenarios, the mainstream reinforcement methods can be divided into three categories: basic simple reinforcement method, professional tool reinforcement method, and combined reinforcement method.

[0005] Basic and simple reinforcement methods, such as wrapping with stretch film, strapping, and rope binding, rely on the binding force of flexible materials to restrain goods. These methods are low-cost and easy to operate, but they have significant drawbacks: stretch film wrapping results in uneven stress, easily damaging goods at the edges and corners, and loosening in the central area, leading to creep and loosening during long-term transportation; it also requires large quantities per use and is environmentally unfriendly. Straps and ropes have limited binding points, achieving only localized tightening and failing to prevent interlayer slippage and lateral tipping; they are prone to loosening due to long-term vibration and can damage goods upon unpacking.

[0006] Specialized tool-based reinforcement methods, represented by snap-on fasteners, frame-type corner protectors, integral side panels, and pallet binding devices, provide restraint through rigid or semi-rigid components. While these methods offer better stability than simple reinforcement, they lack versatility, often relying on specific pallet sizes and cargo shapes, resulting in poor adaptability. Some devices are structurally complex and time-consuming to assemble and disassemble, hindering rapid loading and unloading. Furthermore, most are custom-made components, leading to high procurement and maintenance costs, making large-scale adoption difficult across multiple product categories and specifications.

[0007] Combined reinforcement methods typically use stretch film, binding straps, corner protectors, and baffles in combination to balance constraint strength and protective effect. However, this method involves more procedures, takes longer, uses a wider variety of materials, and is difficult to manage and recycle, leading to increased overall costs. Furthermore, the combination of different materials relies on manual experience, resulting in inconsistent reinforcement quality and making it difficult to meet the requirements of automated and standardized logistics operations.

[0008] In summary, existing palletized cargo reinforcement methods generally suffer from drawbacks such as insufficient versatility, low operational efficiency, high overall costs, and poor environmental performance, making it difficult to simultaneously adapt to the demands of modern logistics that require diverse cargo sizes, multi-scenario transshipment, high-efficiency operations, and green, low-carbon practices. Therefore, it is necessary to develop a pallet reinforcement auxiliary device and method that is highly versatile, quick to assemble and disassemble, reliably restrained, reusable, and cost-effective, in order to systematically address the core shortcomings of existing technologies. Summary of the Invention

[0009] To meet the demands of modern logistics that require multi-specification goods, multi-scenario transfer, high-efficiency operation, and green and low-carbon practices, this application provides a modular, reusable pallet cargo reinforcement device and method.

[0010] The modular, reusable palletized cargo securing device provided in this application adopts the following technical solution: A modular, reusable pallet cargo securing device includes pre-installed fixing bases and multiple straps connected to the pallet. The pallet is polygonal. The number of pre-installed fixing bases is the same as the number of sides of the pallet, or the number of pre-installed fixing bases is half the number of sides of the pallet. If the number of pre-installed fixing bases is half the number of sides of the pallet, the pre-installed fixing bases are located on both symmetrical sides of the pallet. If the number of pre-installed fixing bases is the same as the number of sides of the pallet, the pre-installed fixing bases are located on each side of the pallet. Each pre-installed fixing base is provided with multiple handle holes, which are symmetrically arranged along the pre-installed fixing base. The handle holes are used for connecting and securing the ends of the straps.

[0011] By adopting the above technical solution, when using the product, the user first connects the pre-set fixing base to the pallet before stacking the goods. If two pre-set fixing bases are set and symmetrically arranged on opposite sides of the pallet, a pull-type binding structure can be formed, ensuring that the goods are evenly stressed and stably restrained, effectively preventing the goods from tilting, shifting, or tipping over. If four pre-set fixing bases are set... Each strap is positioned around the pallet to form a four-sided reinforcement system, providing comprehensive restraint for goods from all four directions. This offers a wider restraint range and higher stability, making it particularly suitable for transporting oversized, heavy-duty, easily tipped-over, and high-stacking goods. Based on the volume, weight, and stacking height of the goods, an appropriate number of straps are selected. One end of the strap is pre-fixed to the handle hole on one side of the pallet. After pallet stacking, the other end of the strap is fixed to the corresponding handle hole on the pre-set fixing base on the opposite side. The tension of the straps can be easily adjusted manually to ensure all goods are within the effective protection range of the straps. The pre-set fixing base serves as the hub connecting the pallet and the straps. Both the pre-set fixing base and the straps are reusable, adaptable to various goods sizes and transport scenarios, simple to operate, highly efficient, and meets the green and low-carbon requirements of modern logistics.

[0012] Optionally, one end of the binding strap is tied to a handle hole on one side, and the other end is tied to a handle hole on the opposite side; or both ends of the binding strap are fixedly connected to elastic clips, and multiple elastic clips are fixedly connected to the binding strap. The elastic clip at the end of the binding strap passes through the handle hole and engages with two adjacent elastic clips. The elastic clip has two arc-shaped parts for fitting the elastic clips; or both ends of the binding strap are fixedly connected to elastic buckles, and multiple hanging holes are provided on the binding strap. The elastic buckles can directly hook onto the handle hole, or they can pass through the handle hole and hook onto the hanging hole.

[0013] By adopting the above technical solution, users can directly tie the two ends of the strap to the handle hole, making the operation simple and quick. A single person can quickly complete the strapping operation, greatly improving the efficiency of logistics loading and unloading. The elastic plate at the end of the strap passes through the handle hole and engages between two elastic rings. The cooperation between the elastic plate and the elastic rings forms a two-way limiting and self-locking fixation. Moving the elastic locking pin creates a gap between the elastic locking pin and the limiting pin, allowing the hanging hole to pass through. The locking body hooks into the hanging hole. After releasing, the elastic locking pin automatically abuts against the limiting pin, and the locking block engages in the slot. Rotating the locking sleeve moves it to the outside of the locking block, forming an axial limiting and anti-loosening constraint on the locking block. Structurally, this completely prevents the locking block from falling out of the slot, achieving double anti-loosening and triple insurance. It remains stable and reliable even under heavy loads and high-frequency use. Optionally, the elastic latch includes a latch body, which is annular. One end of the latch body is hinged to an elastic locking post, and the other end is fixedly connected to a limiting post. A slot is fixedly connected to the limiting post, and a locking block for insertion into the slot is fixedly connected to the elastic locking post. A locking sleeve is threadedly connected to the limiting post.

[0014] By adopting the above technical solution, when using the device, the user moves the elastic locking pin to create a gap between the elastic locking pin and the limiting pin, allowing the hook hole to pass through. This allows the locking body to hook onto the hook hole. After releasing, the elastic locking pin automatically abuts against the limiting pin, and the locking block engages in the slot. The elastic locking pin can be manually moved to create a through gap, and it automatically springs back to close after being released. No complicated alignment or tools are required, and a single person can quickly complete the hooking, locking, and disassembly, greatly improving work efficiency. Finally, the locking sleeve is rotated to move it to the outside of the locking block, forming an axial limit and anti-disengagement constraint on the locking block. Structurally, this completely prevents the locking block from falling out of the slot, achieving double anti-loosening and triple insurance. It remains stable and reliable even under heavy loads and high-frequency use.

[0015] Optionally, the pre-set fixing base is provided with bolt holes for bolts to pass through. The tray is a perforated tray, and the stud end of the bolt passes through the bolt hole and is threaded onto the tray.

[0016] By adopting the above technical solution, when using the device, the bolt passes through the mounting hole of the pre-set fixing base and is threaded onto the perforated pallet, fixing the pre-set fixing base and the perforated pallet together. No complicated tooling is required, and a single person can quickly install it, resulting in high work efficiency. The fixing base and the perforated pallet are detachable, replaceable, and reusable, which is conducive to maintenance and recycling, meets the requirements of green and low-carbon logistics, and the bolt fixing connection has high strength and is not easy to loosen. It can withstand the tension and vibration during the transfer of goods, and has strong overall stability.

[0017] Optionally, the pre-set fixing base is provided with a flexible mounting hole, which is located on the side of the pre-set fixing base away from the handle hole. The flexible mounting hole is used to insert the fiber tape. After the fiber tape passes through the flexible mounting hole, it is connected to the tray column to fix the pre-set fixing base and the tray.

[0018] By adopting the above technical solution, when using the device, the user places the pre-installed fixing base at the corresponding position on the non-drillable pallet, ensuring that the elliptical, elongated, flexible mounting holes on the pre-installed fixing base face the pallet uprights. A fiber tape is then passed through the flexible mounting holes and wrapped, tied, or locked to the pallet uprights. The fiber tape's binding action reliably fixes the pre-installed fixing base to the pallet uprights, completing the pre-installation positioning of the pre-installed fixing base on the non-drillable pallet. The fiber tape connection and fixation eliminates the need for drilling, tapping, or using bolts on the pallet, making it suitable for all types of pallets, including non-drillable pallets, wooden pallets, and plastic pallets, thus expanding its applicability. Both the fixing base and the fiber tape are detachable and reusable, meeting the requirements of green, low-carbon, and recyclable logistics.

[0019] Optionally, one end of the fiber tape passes through the flexible mounting hole and is tied to the pre-set fixed base, while the other end is tied to the pallet column; or one end of the fiber tape is fixedly connected to a rope, which is looped onto the pallet column and fixed to the column in a non-removable manner, while the other end of the fiber tape is fixedly connected to a rivet. The fiber tape has multiple rivet holes, and after the end of the fiber tape passes through the flexible mounting hole, the rivet is inserted into the fiber tape to achieve fixation.

[0020] By adopting the above technical solution, users can use fiber straps for binding and fixing without drilling, tapping, or damaging the pallet. It is perfectly compatible with various types of pallets, such as non-drillable pallets, wooden pallets, and plastic pallets, and has strong versatility. The rope is directly looped onto the pallet upright to form a non-removable fixation, which has high connection strength and is not easy to shift or fall off under the vibration and pulling of transportation, ensuring the overall stability of the base. The fiber strap has multiple rivet holes, which can be used to fix it with end rivets. The locking hole position can be freely selected according to the actual installation distance, and the length can be adjusted in multiple levels, making it more adaptable.

S3. Cargo stacking: Arrange the cargo neatly in the center of the pallet, ensuring that the cargo is within the area enclosed by the pre-set fixed base, so that the cargo is placed stably and without obvious off-center loading.

[0027] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described can be combined in any suitable manner in one or more embodiments or examples. Example

[0030] This application provides a modular, reusable pallet cargo reinforcement device, referring to... Figure 1 , Figure 2 and Figure 3 This system includes a pre-installed fixing base 1 connected to the pallet 3 and multiple binding straps 2. The pre-installed fixing base 1 serves as the hub connecting the pallet 3 and the binding straps 2, enabling the binding straps 2 to reinforce the goods on the pallet 3. Different numbers of pre-installed fixing bases 1 and binding straps 2 can be selected according to different needs, achieving the beneficial effects of adapting to various specifications of goods, providing stable restraint, facilitating assembly and disassembly, and allowing for recycling. This is because by rationally setting the number of bases and the connection method, the stress on the goods can be changed, ensuring that the goods are effectively restrained in all directions, and facilitating operation and subsequent recycling.

[0031] Specifically, the pre-set fixing base 1 is provided with multiple handle holes 11, which are symmetrically arranged along the pre-set fixing base 1. The number of handle holes 11 can be odd or even, for example, four is common, but not limited to this. The handle holes 11 are generally circular through holes, and their function is to allow the ends of the binding straps 2 to be connected and fixed. In some special cases, the handle holes 11 can also be designed as square or oval shapes to adapt to the connection requirements of different types of binding straps 2.

[0032] The tray 3 can be polygonal. The number of pre-set fixing bases 1 is the same as the number of sides of the tray 3, or the number of pre-set fixing bases 1 is half the number of sides of the tray 3. If the number of pre-set fixing bases 1 is half the number of sides of the tray 3, then the pre-set fixing bases 1 are located on both sides of the tray 3. If the number of pre-set fixing bases 1 is the same as the number of sides of the tray 3, then the pre-set fixing bases are located on each side of the tray 3. For example, if the pallet is quadrilateral, each pallet 3 is equipped with 2 or 4 pre-set fixing bases 1. If 2 are set, these 2 pre-set fixing bases 1 are located on the symmetrical sides of the pallet 3, which can form a pull-type binding structure, so that the goods are evenly stressed from left to right and the constraint is stable, which can effectively prevent the goods from tilting, shifting or tipping over. If 4 are set, the 4 pre-set fixing bases 1 are located on the four sides of the pallet 3, which can form a four-sided enclosed reinforcement system, which can constrain the goods from the front, back, left and right directions in all directions. The restraint range is larger and the stability is higher, which is especially suitable for the transfer scenarios of oversized, heavy-duty, easily tipped over, and high-stacked goods.

[0033] There are several ways to connect the pre-installed fixed base 1 to the pallet 3. One way is that the pre-installed fixed base 1 has bolt holes 12, and the number of bolt holes 12 is not limited to two. When the pallet 3 is a perforated pallet 3, such as a wooden pallet 3, the stud end of the bolt passes through the bolt hole 12 and is threaded onto the wooden pallet 3. This connection method makes the fixed base and the perforated pallet 3 detachable, removable, replaceable, and reusable, which is conducive to maintenance and recycling, meets the requirements of green and low-carbon logistics, and the bolt fixing connection has high strength, is not easy to loosen, can withstand the tension and vibration during the transfer of goods, and has strong overall stability.

[0034] Another method involves a flexible mounting hole 13 on the pre-installed fixing base 1. The flexible mounting hole 13 is located on the side of the pre-installed fixing base 1 away from the handle hole 11 and is an elliptical elongated slot for threading the fiber tape 14. The fiber tape 14 passes through the flexible mounting hole 13 and connects to the pallet 3 upright 31 to secure the pre-installed fixing base 1 and the pallet 3. This method eliminates the need for drilling, tapping, or using bolts on the pallet 3, making it suitable for all types of pallets 3, including non-drillable pallets 3, wooden pallets 3, and plastic pallets 3, thus expanding its applicability. Furthermore, both the fixing base and the fiber tape 14 are detachable and reusable, meeting the requirements of green, low-carbon, and recyclable logistics. There are several ways to connect the fiber tape 14 to the tray 3 uprights 31 and the pre-set fixing base 1. For example, one end of the fiber tape 14 can pass through the flexible mounting hole 13 and be tied to the pre-set fixing base 1, while the other end can be tied to the tray 3 uprights 31. Alternatively, one end of the fiber tape 14 can be fixedly connected to a loop 141, which is then fixed to the tray 3 uprights 31 and cannot be detached. The other end of the fiber tape 14 can be fixedly connected to a rivet 142. The fiber tape 14 has multiple rivet holes 143. After the end of the fiber tape 14 passes through the flexible mounting hole 13, the rivet 142 is inserted into the fiber tape 14 for fixation. The former method achieves connection through binding, which is simple to operate and does not damage the tray 3. The latter method provides a high connection strength between the loop 141 and the uprights 31. The fiber tape 14 has multiple rivet holes 143, which, together with the end rivet 142, can be inserted for fixation. The locking hole position can be freely selected according to the actual installation distance, achieving multi-level length adjustment and greater adaptability.

[0035] Specifically, the binding straps 2 play a direct role in securing the goods within the entire reinforcement system. The binding straps 2 are made of materials with high elasticity, resilience, strength, wear resistance, and UV resistance to meet the demands of high-intensity, high-frequency, and long-term outdoor use. For example, rubber straps are made of natural or synthetic rubber, offering excellent elasticity and abrasion resistance; latex straps are a blend of latex filaments and high-strength fiber fabrics, balancing elasticity and tensile strength; elastic straps use highly elastic polyurethane material, possessing excellent stretch recovery and weather resistance; and high-elasticity polyester straps are a blend of high-elasticity polyester and latex filaments, maintaining high elasticity while exhibiting excellent fatigue resistance and UV resistance. These binding straps 2, made of different materials, allow the elastic structure to adapt to the shape and stacking height of the goods, achieving comprehensive wrapping for irregular and multi-sized goods, preventing looseness or partial suspension. Furthermore, vibrations and impacts generated during transportation can be buffered and absorbed by the elastic straps, reducing bumps, shifting, and damage to the goods, thus improving transport safety. Its combination of high strength and elasticity provides sufficient locking force without damaging goods or pallets 3 due to rigid tension, and it is not prone to loosening or falling off during long-term transportation. Its UV resistance ensures that the straps 2 are not prone to aging, embrittlement, or failure in outdoor storage and open-air transportation scenarios, exhibiting strong environmental adaptability and stable performance over long-term use. Its abrasion resistance guarantees that the straps 2 are not easily worn or broken during repeated use and friction with goods and pallets 3, resulting in a long service life and multiple recycling options, reducing operating costs.

[0036] One end of the binding strap 2 is tied to the handle hole 11 on one side, and the other end is tied to the handle hole 11 on the opposite side. This connection method is simple to operate and quick to learn, allowing a single person to quickly complete the binding operation, greatly improving the efficiency of logistics loading and unloading. Two pre-set fixed bases 1 are symmetrically arranged on both sides of the pallet 3, and are tied in opposite directions with multiple binding straps 2, resulting in even force distribution and good stability, which can effectively prevent goods from tilting, shifting, or tipping over. By selecting different handle hole positions 11 and different numbers of binding straps 2, it can also flexibly adapt to goods of different sizes, heights, and weights, meeting the binding needs of multiple types of goods.

[0037] The implementation principle of this embodiment is as follows: This modular, reusable pallet 3 cargo reinforcement device, by reasonably setting the number and position of pre-set fixed bases 1 and using binding straps 2 with a binding connection method, can flexibly adjust the reinforcement method according to the specifications, weight, stacking height, and transfer scenarios of different goods, thereby achieving stable constraint on the goods. The selection of multiple connection methods and materials not only facilitates operation and improves logistics efficiency, but also ensures the recyclability of the device, reduces usage costs, and meets the needs of green and low-carbon modern logistics. Compared with traditional pallet 3 cargo reinforcement methods, it has stronger versatility, better stability, and higher environmental protection. Example

[0038] The difference between this embodiment and the above embodiments is that: (Refer to...) Figure 4 , Figure 5 and Figure 6 Both ends of the binding strap 2 are fixedly connected to elastic retaining plates 21, and multiple elastic retaining rings 22 are fixedly connected to the binding strap 2. The elastic retaining plates 21 at the ends of the binding strap 2 pass through the handle holes 11 and are engaged with two adjacent elastic retaining rings 22. The elastic retaining plates 21 are provided with two arc-shaped parts, which are used to fit the elastic retaining rings 22. When the elastic retaining plates 21 pass through the handle holes 11 and are engaged between the elastic retaining rings 22, the arc-shaped parts on the elastic retaining plates 21 can fit with the curved surface of the elastic retaining rings 22, and the force is evenly distributed, effectively reducing stress concentration, avoiding deformation and tearing at the engagement point, and improving the connection strength and service life. The cooperation between the elastic retaining plates 21 and the elastic retaining rings 22 forms a two-way limiting and self-locking fixation, which is not easy to slip off or loosen under the action of transportation vibration, bumps and tension, and the binding reliability is high. Multiple elastic retaining rings 22 are provided on the binding strap 2. Different retaining ring positions can be selected to engage according to the volume of goods, stacking height, and binding tightness requirements, so as to achieve flexible adjustment of tension and adapt to goods of various specifications.

[0039] The implementation principle of this embodiment is as follows: This modular, reusable pallet 3 cargo reinforcement device, through the reasonable setting of the number and position of pre-set fixed bases 1, and the binding straps 2 using the connection method of elastic clamping plates 21 passing through handle holes 11 and snapping into elastic clamping rings 22, can flexibly adjust the reinforcement method according to the specifications, weight, stacking height, and transfer scenarios of different goods, thereby achieving stable restraint of the goods. The selection of multiple connection methods and materials not only facilitates operation and improves logistics efficiency, but also ensures the recyclability of the device, reduces usage costs, and meets the needs of green and low-carbon modern logistics. Compared with traditional pallet 3 cargo reinforcement methods, it has stronger versatility, better stability, and higher environmental protection. Example

[0040] The difference between this embodiment and the above embodiments is that: (Refer to...) Figure 7 , Figure 8 and Figure 9The binding strap 2 has elastic buckles 23 fixedly connected to both ends. Multiple hook holes 24 are provided on the binding strap 2. The elastic buckles 23 can directly hook onto the handle hole 11, or they can pass through the handle hole 11 and hook onto the hook hole 24. When binding, simply align the elastic buckle 23 with the handle hole 11 or hook onto the hook hole 24 to lock, eliminating the tedious steps of binding, knotting, threading, and adjusting. A single person can quickly complete binding and unbinding, significantly improving logistics efficiency. The binding strap 2 has multiple hook holes 24, which, together with the multiple handle holes 11 on the base, allow for flexible selection of hook positions and adjustment of binding tightness according to actual needs. The elastic buckles 23 can either directly hook onto the handle hole 11 for quick fixation, or pass through the handle hole 11 and hook onto the hook hole 24 on the binding strap 2 itself. The two connection methods can be freely switched, adapting to goods of different sizes and stacking heights, thus broadening its applicability.

[0041] The elastic latch 23 includes a latch body 231, which is annular. One end of the latch body 231 is hinged to an elastic locking post 232, and the other end is fixedly connected to a limiting post 234. A slot 235 is fixedly connected to the limiting post 234. A locking block 233 for inserting into the slot 235 is fixedly connected to the elastic locking post 232. A locking sleeve 236 is threadedly connected to the limiting post 234. In use, the elastic locking pin 232 is moved to create a gap between the elastic locking pin 232 and the limiting pin 234, allowing the hanging hole 24 to pass through. The locking body 231 hooks onto the hanging hole 24. After release, the elastic locking pin 232 automatically abuts against the limiting pin 234, and the locking block 233 is engaged in the slot 235. Finally, the locking sleeve 236 is rotated to move it to the outside of the locking block 233, forming an axial limit and anti-disengagement constraint on the locking block 233. Structurally, this completely prevents the locking block 233 from falling out of the slot 235, achieving double anti-loosening and triple insurance. It remains stable and reliable even under heavy load and high-frequency use.

[0042] Furthermore, the connection between the binding strap 2 and the pre-installed fixing base 1 can be achieved using elastic hooks and hanging holes 24. Elastic hooks are fixedly connected to both ends of the binding strap 2, and multiple hanging holes 24 are provided on the binding strap 2. The elastic hooks can directly hook onto the handle hole 11, or pass through the handle hole 11 to hook onto the hanging hole 24. The elastic hook includes a hook body, which is a semi-circular shape and is used to hook onto the hanging hole 24.

[0043] The advantage of this connection method lies in its extremely simple and quick operation, saving a significant amount of time in logistics operations. When bundling, workers simply align the elastic buckle 23 with the handle hole 11 or the hanging hole 24 and hook it in place. Unlike traditional methods, there's no need for cumbersome binding or knotting. A single person can quickly complete the bundling and unbundling work, greatly improving logistics efficiency. Furthermore, because the binding strap 2 has multiple hanging holes 24, combined with the multiple handle holes 11 on the base, the hooking position can be flexibly selected according to actual needs, thus easily adjusting the tightness of the binding. The two connection methods of the elastic buckle 23—directly hooking onto the handle hole 11 and hooking through the handle hole 11 onto the hanging hole 24 of the binding strap 2 itself—can be freely switched, adapting well to goods of different sizes and stacking heights, making it widely applicable. In addition, the special structural design of the elastic latch 23, through the engagement of the latch block 233 and the latch slot 235, plus the axial limiting and anti-disengagement constraint of the locking sleeve 236 on the latch block 233, achieves double anti-loosening and triple insurance, which can ensure the stability and reliability of the connection even under heavy load and high frequency of use.

[0044] The implementation principle of this embodiment is as follows: By adopting the connection method of elastic buckle 23 and hanging hole 24, the connection process between the binding strap 2 and the pre-set fixed base 1 is simplified. The convenient operation and flexible adjustment of the elastic buckle 23 improve the efficiency of logistics operations and the adaptability of the device to different goods. At the same time, the special structural design of the elastic buckle 23 ensures the stability and reliability of the connection, enabling the reinforcement device to play a good role in various logistics scenarios. Compared with traditional connection methods, it better meets the needs of modern logistics for speed, efficiency, and stability. Example

[0045] This application provides a modular, reusable pallet 3 cargo reinforcement method, comprising the following steps: S1. Selection and Installation of Pre-installed Fixing Bases 1: Select the corresponding fixing base installation method according to the type of pallet 3. For perforated pallets 3, such as wooden pallets 3, arrange two or four pre-installed fixing bases 1 on the symmetrical sides or four sides of the pallet 3. Secure the bases to the pallet 3 by threading bolts through the bolt holes 12 on the bases. This installation method offers the advantages of a strong connection, the ability to withstand significant tension and vibration, and a simple and quick installation process that can be performed by a single person. During installation, ensure the bolts are tightened to prevent the bases from loosening. For non-perforated pallets 3, arrange two or four pre-installed fixing bases 1 on the symmetrical sides or four sides of the pallet 3. Use fiber tape 14 to pass through the elliptical, elongated, flexible mounting holes 13 on the bases. There are two specific installation methods. One method is to tie one end of the fiber tape 14 to the base and the other end to the upright 31 of the pallet 3, thus completing the installation of the pre-installed fixed base 1. The other method is to use a rope 141 to be looped onto the upright 31 of the pallet 3, pass the other end of the fiber tape 14 through the flexible mounting hole 13, and fix it by inserting a rivet 142 into the rivet hole 143 on the fiber tape 14, thus completing the installation of the pre-installed fixed base 1. Neither of these methods requires drilling holes in the pallet 3, making them suitable for various types of pallets 3, highly versatile, and both the fiber tape 14 and the base can be reused, meeting the requirements of green and low-carbon development.

[0046] S2. Selection and Pre-fixing of Binding Straps 2: Based on the volume, weight, and stacking height of the goods, select binding straps 2 made of high-elasticity, high-strength, wear-resistant, and UV-resistant materials, such as rubber straps, latex straps, elastic straps, and high-elasticity polyester straps, and determine the quantity of binding straps 2. Different goods require different specifications and quantities of binding straps 2 to achieve the best reinforcement effect. For example, for large and heavy goods, it is necessary to select binding straps 2 with higher strength and better elasticity, and increase the quantity of binding straps 2. Pre-connect and fix one end of each binding strap 2 to the corresponding handle hole 11 on the pre-set fixing base 1 on one side of the pallet 3. This step prepares for subsequent stacking and further reinforcement of the goods.

[0047] S3. Cargo Stacking: Neatly stack the goods in the central area of ​​pallet 3, ensuring the goods are entirely within the enclosure of the pre-positioned fixed base 1, guaranteeing stable placement and no significant off-center loading. Neat stacking distributes weight evenly across pallet 3, preventing tilting or tipping during transport due to off-center loading. Simultaneously, the goods being within the enclosure of the pre-positioned fixed base 1 facilitates effective restraint using straps 2 later.

[0048] S4. Tightening and securing the binding straps 2: After the goods are stacked, straighten and tighten each binding strap 2. According to the selected binding strap 2 structure, secure the other end to the corresponding handle hole 11 on the pre-set fixing base 1 on the opposite side. If a tie-on binding strap 2 is used, tie the end of the binding strap 2 directly into the handle hole 11 to complete the pull-type fixation; if a binding strap 2 with elastic clamp 21 and elastic retainer 22 is used, pass the elastic clamp 21 at the end of the binding strap 2 through the handle hole 11 and engage it between two adjacent elastic retainers 22, so that the arc-shaped part on the elastic clamp 21 fits and limits the elastic retainer 22; if a binding strap 2 with elastic buckle 23 and hanging hole 24 is used, hook the elastic buckle 23 directly into the handle hole 11, or pass it through the handle hole 11 and hook it into the hanging hole 24 on the binding strap 2. If using the annular elastic buckle 23 with locking sleeve 236, first move the elastic locking pin 232 to create a gap for loading, hook the buckle and then release it, allowing the locking block 233 to engage with the locking groove 235. Then rotate the locking sleeve 236 to move it to the outside of the locking block 233 to achieve anti-detachment safety. Different binding straps 2 have their own characteristics, and operators can choose the most suitable method according to the actual situation to ensure that the binding straps 2 firmly restrain the goods to the pallet 3.

[0049] S5. Tension Adjustment: Based on the cargo size and bundling requirements, adjust the tension of the binding strap 2 by selecting different handle holes 11, different elastic retaining ring positions 22, or different hanging hole positions 24. This ensures the binding strap 2 evenly wraps the cargo, preventing it from becoming loose or wobbling. Appropriate tension is crucial for the safe transport of goods. Insufficient tension may cause the cargo to sway or shift during transport; excessive tension may damage the cargo or pallet 3. Therefore, the tension of the binding strap 2 should be flexibly adjusted according to the specific conditions of the cargo.

[0050] S6. Overall Inspection and Confirmation: Check that all pre-installed fixing bases 1 are secure, that the binding straps 2 are reliably tensioned, that the connecting structures are in place, and that the goods are stably restrained. After confirming that everything is correct, complete the reinforcement of the entire pallet 3. This step is crucial to ensuring the quality of the entire reinforcement process. Through careful inspection, potential problems can be identified and resolved in a timely manner, ensuring the safety of the goods during transportation.

[0051] The implementation principle of this embodiment is as follows: This reinforcement method, through scientific and reasonable steps, combines the selection of appropriate pre-installed fixing bases 1 and binding straps 2 to orderly and effectively reinforce the goods on pallets 3. Appropriate base installation methods are selected according to different types of pallets 3 to ensure the stability of the bases; appropriate binding straps 2 are selected according to the actual situation of the goods and their tension is adjusted reasonably to achieve good restraint of goods of different specifications, improving the stability of the goods during logistics transportation. Each step works closely together to ultimately achieve reliable reinforcement of the goods on pallets 3. Compared with existing reinforcement methods, this method improves operational efficiency, reduces logistics costs, and also meets the needs of green and low-carbon modern logistics, representing a substantial improvement and optimization of existing technology.

[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
