Technical Field

[0001] This utility model relates to the field of cargo transportation and securing technology, specifically to a modular and expandable cargo organization device and cargo securing method for transportation spaces such as truck beds and containers. Background Technology

[0002] In the field of automobile freight transportation, how to effectively secure goods to prevent them from sliding or colliding during transport is an important issue. Existing technologies mainly employ two methods: one is using rigid frames or partitions, whose fixed dimensions cannot flexibly adapt to goods of different shapes and sizes, resulting in low space utilization; the other is using ropes, bandages, etc., for binding, but this method is cumbersome to operate, relies on personnel experience, and is prone to loosening during long-distance travel, resulting in poor reliability.

[0003] Therefore, there is an urgent need in this field for a cargo organization device that can be quickly assembled and disassembled, flexibly adjusted according to the size of the cargo and cargo box, has a firm and reliable connection, and is highly versatile. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a plug-in expandable cargo organization device. This device has the advantages of modularity, expandability, high connection strength, convenient installation and adjustment, and high space utilization.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a plug-in expandable cargo organization device, the innovation of which lies in comprising: Multiple panel units, each with a bidirectional dovetail tenon structure on its thickness edge surface, are used to achieve a detachable interlocking connection between adjacent panel units; At least one pin has a cavity structure at its bottom that mates with an array of insertion holes on the first surface of the panel unit. The outer wall of the cavity structure is a guide surface, which is a polygon with a rounded transition to achieve an interference fit with the insertion holes. The top of the pin has multiple threaded holes. At least one fastener has a mounting surface and a blocking surface that are perpendicular to each other. The mounting surface is provided with an array of multiple through holes, which are connected to the threaded holes of the pin by bolts.

[0006] Furthermore, the second surface of the panel unit is provided with multiple weight-reduction openings.

[0007] Furthermore, the bottom of the threaded hole of the pin is machined with a recessed structure.

[0008] Furthermore, the blocking surface of the fixing member is provided with a hollow structure.

[0009] Furthermore, an arc-shaped notch is provided at the intersection of the mounting surface and the blocking surface of the fastener.

[0010] Furthermore, the bidirectional dovetail joint structure allows the panel unit to be spliced ​​and expanded in both the length and width directions.

[0011] The beneficial effects of this utility model are: Highly modular and infinitely expandable: The two-way interlocking design of the panel units allows the platform size to be flexibly changed according to the cargo box and the goods, making it extremely versatile.

[0012] Secure connection and easy assembly / disassembly: The interference fit between the pins and the panel provides reliable connection strength, while the pre-assembled "fixture-pin" assembly allows for easy plugging and unplugging, resulting in extremely high deployment efficiency without the need for specialized tools.

[0013] The fixed position and angle are flexible and adjustable: the array of plug holes and multiple sets of through holes allow the position and angle of the fastener to be infinitely adapted to the shape of the goods, achieving precise and tight fixation, greatly improving space utilization and fixing effect.

[0014] Optimized structure, lightweight and durable: The weight-reducing openings on the panel and the hollow and notched designs of the fasteners achieve lightweighting while ensuring structural strength, making them easy to handle and store.

[0015] Non-destructive installation: The entire system exists independently of the cargo box, requiring no drilling or modification to the vehicle's sheet metal, thus protecting the vehicle's integrity. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model.

[0026] like Figure 1-7 As shown, a plug-in expandable cargo organization device mainly consists of three core components: panel unit 1, pins 2, and fasteners 3.

[0027] Panel unit 1 is the basic module constituting the support platform. Its body has a thickness edge surface 1-3 and a first panel surface 1-1 and a second panel surface 1-2 located on opposite sides in the thickness direction. The thickness edge surface 1-3 is provided with complementary protrusions 1-3a and recesses 1-3b (preferably a two-way dovetail joint structure). This structure allows any two panel units 1 to interlock along the mating direction, achieving infinite expansion. The first panel surface 1-1 is provided with an array-type interlocking structure 1-1a (such as a matrix arrangement of flower-shaped holes, round holes, or square holes). The second panel surface 1-2 is provided with structurally optimized weight-reducing openings 1-2a.

[0028] The pin 2 is an interface component connecting the panel unit 1 and the fastener 3. It has a first pin surface 2-1 and a second pin surface 2-2. The sidewall of the pin 2 forms a guide surface 2-3, which is a polygon with a rounded transition. The first pin surface 2-1 has multiple threaded holes 2-1a for connecting the fastener 3. The bottom of each threaded hole 2-1a has a recessed structure 2-1b. The second pin surface 2-2 has a cavity structure 2-2a in the middle for forming an interference fit with the array-type insertion structure 1-1a of the panel unit 1.

[0029] The fastener 3 (taking the L-type as an example) is a functional component that directly acts on the cargo. It includes a mounting surface 3-1 and a blocking surface 3-2 that is substantially perpendicular to it. The mounting surface 3-1 has multiple sets of through holes 3-1a, which are arranged in an array. The blocking surface 3-2 has a hollow structure 3-2a. At the intersection of the mounting surface 3-1 and the blocking surface 3-2, there is a notch 3-3 (preferably a rounded notch).

[0030] The device is connected into a unit by fasteners 4 (such as bolts) passing through the through hole 3-1a of the fixing member 3 and screwing them into the threaded hole 2-1a of the pin 2. The unit is then fixed to the support platform by inserting the pin 2 into the plug-in structure 1-1a of the panel unit 1.

[0031] Example: Cargo securing in the cargo compartment of a pickup truck.

[0032] Platform Setup: First, estimate the number of panel units 1 needed based on the length and width dimensions of the pickup truck bed. Take two panel units 1, align the protrusions 1-3a of one panel unit with the recesses 1-3b of the other, and gently push them in along the fitting direction until they are properly fitted. Repeat this process, from left to right and from back to front, until the assembled platform covers the bottom of the cargo bed.

[0033] Pre-assembly of fixing points: Determine the fixing points at the corners where the goods 6 are to be placed. Take four pins 2 and four L-shaped fasteners 3. Pass the fasteners 4 (bolts) through the through holes 3-1a on the mounting surface 3-1 of the fasteners 3 and screw them into the threaded holes 2-1a of the pins 2 to pre-assemble them into four assemblies.

[0034] Installation fixing points: Align these four assemblies with the corresponding array-type plug-in structures 1-1a on the panel platform, press the plug pins 2 vertically downwards by hand, and use the guide surfaces 2-3 to guide them to be inserted smoothly until they are tightly connected.

[0035] Loading and fine-tuning: Place the goods on the prepared platform and push them until they initially contact the blocking surface 3-2 of the fastener 3. Observe the gap between the goods 6 and the fastener 3. If the gap is not ideal, loosen the fastener 4 slightly, adjust the angle of the fastener 3 by selecting different through holes 3-1a for connection, or adjust the insertion position of the assembly 5 on the panel, and then tighten the fastener 4 again until the goods are tightly and securely clamped.

[0036] Disassembly and Storage: After transportation, simply remove the goods 6, then use your hands or tools to pry open the perforated structure 3-2a of the fixing part 3-2 and pull upwards to pull out the assembly 5. The panel unit 1 can be separated piece by piece, and all components can be stacked for storage.

[0037] The above description is only used to illustrate the technical solution of this utility model and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
