Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cargo transportation fixing, in particular to a modular and expandable cargo organizing device for transportation space such as automobile cargo compartment and container and a cargo fixing method. BACKGROUND

[0002] In the field of automobile cargo transportation, how to effectively fix the cargo to prevent it from sliding and colliding during transportation is an important issue. In the prior art, two methods are mainly used: one is rigid frame or partition, which has fixed size and cannot flexibly adapt to cargo of different shapes and sizes, resulting in low space utilization; the other is to use ropes, bandages and other methods for binding, which is complicated to operate, depends on personnel experience, and is prone to looseness in long-distance bumpy transportation, with poor fixing reliability.

[0003] Therefore, there is an urgent need in the art for a cargo organizing device that can be quickly disassembled, flexibly adjusted according to the size of the cargo and cargo compartment, firmly connected, and has strong universality. SUMMARY

[0009] Further, the fixing member comprises: a mounting surface provided with a plurality of through holes for connecting with the connecting portion of the pin through fasteners, and the array arrangement of the plurality of through holes allows the fixing member to be installed at multiple angles relative to the pin in the horizontal plane; a blocking surface substantially perpendicular to the mounting surface for directly contacting and limiting the goods.

[0010] Further, the surface of the blocking surface is provided with a hollow structure for reducing weight and providing an operating force point.

[0011] Further, the intersection of the mounting surface and the blocking surface is provided with a notch for avoiding the round corners or edges of the goods, while also serving to reduce weight.

DETAILED DESCRIPTION

[0028] The present application will be further described below in conjunction with the drawings.

[0029] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and should not be used to limit the present application.

[0030] As shown in the drawings, a plug-in expandable cargo organization device mainly consists of three core components: panel unit 1, pin 2 and fixing part 3. Figures 1-7 The panel unit 1 is the basic module constituting the bearing platform. Its body has a thickness edge surface 1-3 and a panel first surface 1-1 and a panel second surface 1-2 located on the opposite sides in the thickness direction. The thickness edge surface 1-3 is provided with complementary convex part 1-3a and recess 1-3b (preferably bidirectional dovetail structure). This structure allows any two panel units 1 to be embedded in each other along the fitting direction, realizing infinite expansion. The panel first surface 1-1 is provided with an array type plug-in structure 1-1a (such as matrix arranged pattern hole, round hole or square hole). The panel second surface 1-2 is provided with a structure optimized weight reduction opening 1-2a.

[0031] The pin 2 is the interface component connecting the panel unit 1 and the fixing part 3. It has a pin first surface 2-1 and a pin second surface 2-2. The side wall of the pin 2 constitutes a guide surface 2-3, which is a polygon with a circular arc transition. The pin first surface 2-1 is provided with a plurality of threaded holes 2-1a for connecting the fixing part 3. The bottom of the threaded hole 2-1a is processed with a sunken structure 2-1b. The pin second surface 2-2 is provided with a cavity structure 2-2a in the middle, which is used to form an interference fit with the array type plug-in structure 1-1a of the panel unit 1.

[0032] The fixing part 3 (for example, L-shaped) is a functional component directly acting on the cargo. It includes a mounting surface 3-1 and a substantially perpendicular blocking surface 3-2. The mounting surface 3-1 is provided with a plurality of through holes 3-1a, which are arranged in an array. The blocking surface 3-2 is provided with a hollow structure 3-2a. At the intersection of the mounting surface 3-1 and the blocking surface 3-2, a notch 3-3 (preferably R angle notch) is provided.

[0033] The device is connected into a combination by fasteners 4 (such as bolts) passing through the through holes 3-1a of the fixing part 3 and being screwed into the threaded holes 2-1a of the pin 2. The combination is then fixed on the bearing platform by inserting the pin 2 into the plug-in structure 1-1a of the panel unit 1.

[0034] Embodiment: cargo fixing for pickup truck cargo compartment.

[0035]

[0036] ​Platform building: First, estimate the number of panel units 1 needed according to the length and width of the pickup truck cargo bed. Take two panel units 1, align the protrusions 1-3a on the edges of one with the recesses 1-3b on the other, and gently push them in the fitting direction until they are fitted in place. Repeat this process from left to right and from back to front until the platform is fully assembled on the cargo bed floor.

[0037] Fixed point pre-assembly: Determine the fixed points at the corner positions where the goods 6 are expected to be placed. Take four prongs 2 and four L-shaped fixtures 3. Assemble four combined bodies by inserting the fasteners 4 (bolts) through the through-holes 3-1a on the mounting surfaces 3-1 of the fixtures 3 into the threaded holes 2-1a of the prongs 2.

[0038] Installation of fixed points: Align the four combined bodies with the corresponding arrayed plug-in structures 1-1a on the panel platform, respectively, and press the prongs 2 vertically downward with your hand. Use the guidance of the guide surfaces 2-3 to smoothly insert them until they are tightly combined.

[0039] Loading and fine-tuning: Place the goods on the built platform and push them to make preliminary contact with the blocking surfaces 3-2 of the fixtures 3. Observe the gap between the goods 6 and the fixtures 3. If the gap is not ideal, you can slightly loosen the fasteners 4, adjust the angle of the fixtures 3 by connecting them through different through-holes 3-1a, or adjust the plug-in position of the combined body 5 on the panel, then tighten the fasteners 4 again until the goods are tightly and securely clamped.

[0040] Disassembly and storage: After transportation is completed, simply remove the goods 6, then use your hand or a tool to pry the hollow structure 3-2a of the fixture blocking surface 3-2, and pull the combined body 5 out by force. The panel units 1 can be separated piece by piece, and all components can be stacked for storage.

[0041] The above description is only to illustrate the technical solutions of the present application and not to limit it. Other modifications or equivalent replacements made by those skilled in the art to the technical solutions of the present application, as long as they do not deviate from the spirit and scope of the present application, should be covered within the scope of the claims of the present application.
