[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0016] Reference Figures 1-5 This embodiment provides a foldable container for logistics transportation, including a bottom plate 1, two side plates 2, two end plates 4, and a top plate 3. One end plate 4 is provided with a container door 6. The side plates 2 are hinged to the long side of the bottom plate 1 through a first hinge 7, and the end plate 4 is hinged to the short side of the bottom plate 1 through a second hinge 8. The top plate 3 is hinged to the top of one of the side plates 2 through a third hinge 9. Corner connecting mechanisms 5 are provided on the top of both sides of the end plate 4. A limiting and reinforcing plate 10 is provided on the end plate 4 for fastening the side plates 2, the top plate 3, and the end plate 4.
[0017] Specifically, when unfolding and using the equipment, firstly, the operator flips the end plate 4 to a vertical position, then flips the side plate 2 upward so that the positioning hole 53 is aligned with the positioning rod 52 and inserted, thus completing the initial connection of the four corners and laying the basic framework of the box. Then, the top plate 3 is flipped upward to cover the top of the box, achieving the initial positioning of the box. Finally, the limiting and reinforcing plates 10 are locked in sequence by the locking bolts 11, thus achieving a tight connection between the top plate 3 and the end plate 4, and between the side plate 2 and the end plate 4. The locking bolts 11 make the connection more secure, thus tightly compressing the structure composed of the bottom plate 1, side plate 2, end plate 4 and top plate 3 into a whole, thereby obtaining the rigidity and strength required for transportation. When folding, folding is the reverse process of unfolding. It relies on the rotation of the hinge and the guidance of mechanical external force. After unscrewing the locking bolts 11 in sequence and removing the limiting reinforcement plate 10, fold the opposite side plate 2: pull the side plate 2 opposite to the non-hinged top plate 3 inward and lay it flat on the bottom plate 1. Then use a forklift to hook the outer edge of the top plate 3 and move it backward. At this time, the top plate 3 acts as the main action and drags the side plate 2 that is hinged to it through the third hinge mechanism (7) so that the two become a whole composite unit and rotate inward synchronously to cover the opposite side plate 2. Finally, fold the end plate 4: use a forklift or other machinery to pull the two end plates 4 inward in sequence, so that they perfectly cover the top layer of the entire folded stack, complete the folding, and make it convenient to use.
[0018] Furthermore, the corner connection mechanism 5 includes a mounting block 51 fixed to the top side of the end plate 4, and a positioning hole 53 opened on the top side of the side plate 2. A positioning rod 52 adapted to the positioning hole 53 is fixedly connected to one side of the mounting block 51. A locking bolt 11 is provided on one side of the limiting reinforcement plate 10. The side plate 2 and the end plate 4, and the top plate 3 and the end plate 4 are fixedly connected by the locking bolt 11.
[0019] Specifically, the bottom hinge positioning provides the basic connection and rotation basis for the panels. Through the cooperation of the positioning rod 52 and the positioning hole 53, it effectively resists the separation force between the side plate 2 and the end plate 4, and achieves initial vertical positioning. Then, the top plate 3 flips upwards to the other side plate 2, and after the box is initially unfolded, the end plate 4 and the top plate 3 are fastened together by the limiting reinforcement plate 10 and the locking bolt 11. The end plate 4 and the side plate 2 are also fastened together by the locking bolt 11. The quantity is set to 4 end plates, which are fixed to the four corners of the top of the box, thus firmly fixing the end plate 4, side plate 2 and top plate 3 together, forming a stable and torsion-resistant rigid hexahedral structure. Through the folding sequence of "opposing side plate 2 → hinged side plate 2 → top plate 3 and end plate 4", this process is highly consistent with the operation mode of standard logistics machinery such as forklifts. Operators only need to pull down or push up each plate in a fixed order, without complicated judgment, realizing fast and labor-saving operation of large boxes and high work efficiency.
[0020] Furthermore, the base plate 1, side plate 2, end plate 4, and top plate 3 are all independent plates. Each plate includes a rigid planar frame made of metal profiles, and its outer surface is covered with a metal skin. The metal skin is only set on the outer surface of the metal frame of each plate, and its inner surface is an exposed frame structure. The frames of the base plate 1, side plate 2, end plate 4, and top plate 3 are all provided with reinforcing ribs 12.
[0021] Specifically, the metal frame, usually made of high-strength steel or aluminum profiles, forms the "skeleton" of the container and bears the main tensile, compressive, bending, and torsional stresses. This structure achieves maximum load-bearing capacity with minimal materials. Combined with reinforcing ribs 12, it enhances overall strength. The metal skin, such as corrugated steel plates welded or riveted to the frame, is not merely a covering; it acts as a "stress skin," effectively resisting localized deformation and distributing loads. Working in conjunction with the frame, it resists torsional deformation of the container, significantly enhancing overall rigidity and stability. The metal skin can withstand collisions and friction during loading and unloading, as well as the bumps and vibrations during long-distance transport. It is more wear-resistant and damage-resistant than wood or plastic composite materials. Furthermore, the metal skin forms a continuous, seamless barrier, effectively preventing rainwater and dust intrusion, especially in welded cases, protecting the cargo inside. The cutting and welding of the metal frame, as well as the pressing, welding, or riveting of the skin, are mature industrial production processes, easily achieving standardization and large-scale production, thus controlling costs. If local frames or skin are damaged, they can be repaired through welding, patching, or component replacement, resulting in relatively low maintenance costs.
[0022] Furthermore, the first hinge 7, the second hinge 8, and the third hinge 9 are all hinges or sliding hinges.
[0023] Specifically, choose hinges or ring hinges. They have a simple structure, extremely high reliability, and are usually made of metals such as steel, stainless steel, or brass. They have high strength and hardness, are sturdy and durable, and are inexpensive, easy to purchase and replace, easy to install, and convenient to use.
[0024] Furthermore, the side plate 2 and end plate 4 are provided with lifting holes or guide grooves for cooperating with forklift forks.
[0025] Specifically, through dedicated lifting holes or guide slots, it provides a clear and standardized force point and operating interface for forklift forks, simplifying the complex "flipping" action into a simple "linear pulling" or "linear pushing" action. This achieves mechanization to replace manual labor, provides a clear and reliable operating interface for forklifts, and allows the folding and unfolding of all panels to be completed independently and smoothly by the forklift. It simplifies the complex flipping action into a simple linear motion, greatly improving operating efficiency and reducing labor intensity and dependence on skilled workers.
[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
