Description

Technical Field

[0001] This utility model relates to the field of logistics box technology, and in particular to a foldable logistics box. Background Technology

[0002] Logistics boxes, also known as turnover boxes, are widely used in industries such as machinery, automobiles, home appliances, light industry, and electronics. They are acid and alkali resistant, oil resistant, non-toxic, and odorless, and can be used to hold food, etc. They are easy to clean, facilitate the turnover of parts, stack neatly, and are easy to manage. To reduce storage volume and logistics costs during transportation, foldable logistics boxes have emerged.

[0003] In existing folding logistics boxes, all four side panels can be folded outwards, resulting in a flat surface for the four side panels and the bottom panel. While this reduces the box's height, it occupies too much space and is inconvenient for storage. Alternatively, the side panels can be foldable crease plates, further reducing the box's footprint. However, these crease plates are typically made of plastic, and their lifespan decreases with repeated folding. Another option is to fold two side panels inwards, with the other two folded into the base. This method is overly complex and inconvenient to operate. Utility Model Content

Detailed Implementation

[0034] 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 embodiments and accompanying drawings. Here, the illustrative embodiments and descriptions of this utility model are used to explain the present utility model, but are not intended to limit the present utility model.

[0035] It should also be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the solution according to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0036] It should be emphasized that the term "including / comprises" as used herein refers to the presence of a feature, element, step, or component, but does not exclude the presence or addition of one or more other features, elements, steps, or components.

[0037] It should also be noted that, unless otherwise specified, the term "connection" in this article can refer not only to a direct connection, but also to an indirect connection involving an intermediary.

[0038] In the following description, embodiments of the present invention will be illustrated with reference to the accompanying drawings. In the drawings, the same reference numerals represent the same or similar parts, or the same or similar steps.

[0039] To address the numerous technical problems existing in folding logistics boxes in the prior art, this embodiment provides a folding logistics box. The four side panels and top panel of the box can be stacked on the bottom panel, which greatly reduces the height of the folded box and shrinks the space occupied, making it easier to store. The coordinated design of the detachable side panels and the hinge folding mechanism allows the box to be quickly assembled and disassembled, making the assembly and disassembly process simple and quick.

[0040] Reference Figure 1 This utility model embodiment provides a folding logistics box (hereinafter referred to as the box body), including: a base 1, a top cover 2, two oppositely arranged detachable side panels 3, and oppositely arranged first folding side panels 4 and second folding side panels 5. Each panel constituting the logistics box can be made of metal, possessing high load-bearing capacity and impact resistance.

[0041] The folding logistics box in this embodiment has two states: box state and folded state. In the box state, the bottom of the two folding side panels can be folded and installed on the two opposite sides of the base 1 via hinge assemblies. It can be folded to a folded state parallel to the base 1 or unfolded into a box state perpendicular to the base 1. Both ends of the two folding side panels have mounting structures to limit or connect the two detachable side panels 3 to form the four-sided side structure of the box, making the entire box a cubic structure.

[0042] In the folded state of the folding logistics box, the first folding side panel 4 folds onto the base 1, and the second folding side panel 5 folds onto the first folding side panel 4. The two detachable side panels 3 and the top cover 2 are stacked in sequence, and the overall height of the box is shortened to the maximum extent. The overall height of the box is shortened to the sum of the thickness of six panels, which greatly optimizes the space occupation and reduces warehousing and transportation costs.

[0043] In the above embodiments, all six panels are integral panel structures, ensuring the basic load-bearing capacity and avoiding the problems of easy loosening and weak impact resistance of spliced ​​panels. The installation structures at both ends of the folding side panels provide physical constraints on the detachable side panels, improving the overall compressive strength and load-bearing capacity after enclosure. The detachable side panels can be directly removed from the box body, facilitating partial replacement and extending service life. The coordinated design of the detachable side panels and the hinged folding mechanism allows for quick assembly and disassembly of the box body, making the process simple and fast. In the folded state, the base, two folding side panels, two detachable side panels, and the top cover are stacked sequentially, reducing the space occupied without increasing the floor area; the folding side panels are connected to the base via hinge components, ensuring that the mechanical properties and lifespan of the folding side panels are not affected during folding, thus improving the lifespan of the folding side panels and the box body; the structure of each panel of the box body is simple and reliable, the folding method is simple, the operability is strong, and it is easy for operators to assemble and disassemble, making it highly practical.

[0044] In some embodiments, refer to Figure 11 and Figure 12 The installation structure includes a limiting groove structure formed at both ends of the first folding side plate 4 and the second folding side plate 5 in the length direction, facing the inner side of the box, for installing two detachable side plates 3.

[0045] The limiting groove structure is formed by an L-shaped structural member 41 fixedly installed on the outer side of the first folding side plate 4 and the second folding side plate 5 near the end. One flange of the L-shaped structural member 41 is fixedly connected to the main structure of the two folding side plates, and the other flange is parallel and in the same direction as the end face of the two folding side plates along their length. The gap between them forms the limiting groove structure. When the folding logistics box is in the box state, the left and right sides of the two detachable side plates 3 are located within the limiting groove structure. The limiting groove formed by the L-shaped structural member 41 restricts the five degrees of freedom of the detachable side plate 3 by constraining the left and right sides of the detachable side plate 3, thus limiting the detachable side plate 3. At the same time, the L-shaped structural member 41 itself has high strength and is not easily deformed, and can withstand the squeezing force of the goods inside the box on the detachable side plate 3. The L-shaped structural members 41 on both sides of the detachable side plate 3 can also serve as guides, facilitating the assembly and disassembly of the detachable side plate 3. The outer edge of the L-shaped structural component 41 does not extend beyond the outer edge of the folding side panel, ensuring that there are no protrusions after the detachable and folding side panels are folded, thus improving the flatness of the stack. The limiting groove structure allows the detachable side panel 3 to be inserted between the two folding side panels, creating a labyrinth-like structure at the joint between the detachable and folding side panels. Compared to using a foldable disassembly method for all four panels, this enhances the sealing performance of the joint.

[0046] The mounting structure also includes a side plate connecting structure 6, used to connect the adjacent folding side plates and the detachable side plates 3 within the limiting groove structure. The side plate connecting structure 6 restricts the vertical freedom of the detachable side plates 3, preventing them from coming off. The side plate connecting structure 6, combined with the L-shaped structural member 41, can connect the two folding side plates and the two detachable side plates 3 into one unit.

[0047] In some embodiments, refer to Figure 12 and Figure 13 The first folding side plate 4 and the second folding side plate 5 have a clearance structure on the opposite side for installing the side plate connecting structure 6. The side plate connecting structure 6 includes a pin 61, a guide 62, an elastic element 63 and a handle 64.

[0048] Among them, reference Figure 13 The detachable side panel 3, located within the limiting groove structure, has a first mounting hole 65 along its thickness direction, and the two folding side panels have a first through hole 66 along their length direction. When the folding logistics box is in its box state, the projections of the first mounting hole 65 and the first through hole 66 in the thickness direction of the detachable side panel 3 overlap, and the pin 61 is used to pass through the first through hole 66 and insert into the first mounting hole 65. The detachable side panel 3 and the folding side panel form a mechanical hard connection. Compared with traditional snap-fit ​​structures, such as the barbed design of the side panel box, the side panel connection structure 6 in this embodiment has significantly improved resistance to lateral shear force, effectively preventing the side panel from dislodging due to transportation vibration.

[0049] In the above embodiment, the guide member 62 is fixedly connected to the folding side plate. The guide member 62 has a second through hole in its middle, which is coaxially arranged with the first through hole 66. The pin 61 is slidably connected to the second through hole. This arrangement ensures the accurate movement trajectory of the pin 61 and avoids failure caused by uneven wear. One end of the elastic member 63 is fixedly connected to the pin 61, and the other end of the elastic member 63 is fixedly connected to the guide member 62 or the folding side plate. The spring or rubber elastic member can provide a continuous locking force, and the pin 61 automatically locks after insertion. The handle 64 is fixedly located at the end of the pin 61 away from the first through hole 66. The handle 64 is a ring structure, an L-shaped structure, or a T-shaped structure, which is convenient for the user's hand to grip.

[0050] To ensure that the second folding side plate 5 is snapped in flat and attached to the first folding side plate 4, the hinge size connected to the folding side plate can be set to be different, or the installation height of the hinge can be different.

[0051] In some embodiments, refer to Figures 6 to 8 as well as Figure 14The hinge assembly includes a fixed base and a rotating base that are rotatably connected to each other. The bottom surface of the fixed base is fixedly connected to the base 1, and the top surface of the rotating base is fixedly connected to the folding side plate. The rotating base connected to the second folding side plate 5 has an extension section 75 in its middle. The plane of the extension section 75 intersects the plane of the second folding side plate 5, allowing the second folding side plate 5 to fit against the first folding side plate 4 when the first folding side plate 4 is folded down to the base 1. The plane of the extension section 75 intersects (or may be perpendicular to) the plane of the second folding side plate 5, forming a space clearance structure. When the first folding side plate 4 is folded down, the second folding side plate 5 can fit against its surface without interference. (Refer to...) Figure 6 and Figure 7 The second rotating seat 74 is larger than the width of the first rotating seat 72.

[0052] In other embodiments, the portion of the base 1 used for hinged connection with the second folding side panel 5 is a raised structure, higher than the portion of the base 1 used for hinged connection with the first folding side panel 4. This allows the space formed between the second folding side panel 5 and the base 1 to accommodate the first folding side panel 4 when the second folding side panel 5 is folded inwards towards the inside of the housing and parallel to the base 1. This configuration allows the hinges on both folding side panels to be of the same specification, improving versatility.

[0053] In some embodiments, the fixing seat is mounted on the base 1. The distance between the outer edge of the fixing seat for connecting with the first folding side plate 4 and the outer edge of the base 1 is 5-9 mm, specifically 7 mm. The distance between the outer edge of the fixing seat for connecting with the second folding side plate 5 and the outer edge of the base 1 is 23-28 mm, specifically 25.5 mm.

[0054] In some embodiments, refer to Figure 4 , Figure 6 , Figure 7 and Figure 9 The first folding side panel 4, the second folding side panel 5, and the two detachable side panels 3 each include: a first square annular pressure strip 31, a box panel 32, and a square frame 33. The first square annular pressure strip 31 is located at the four edges of the inner side of the box panel 32, and the square frame 33 is located on the outer side of the box panel 32. The first square annular pressure strip 31, the box panel 32, and the square frame 33 are connected by fasteners. The first square annular pressure strip 31 is set at the edge of the box panel 32, which allows the edge of the box panel 32 and the square frame 33 to fit tightly together, increasing the sealing performance.

[0055] The square frame 33 includes an outer frame formed by four square tubes and at least one reinforcing rod 34 fixedly connected to the square tubes within the outer frame. The reinforcing rod 34 can be arranged laterally, longitudinally, or diagonally. The square tubes can be made of aluminum profiles, which are high-strength and lightweight, thus reducing the overall weight of the logistics box while increasing its strength. Compared to traditional single-layer enclosures, such as plastic enclosure boxes, the bending stiffness is improved. The diagonal arrangement of the reinforcing rods 34 can form a triangular stable structure, which can disperse local impact loads.

[0056] In some embodiments, refer to Figure 10 The base 1 includes a bottom frame 11, a support plate 12, and a support limiting member 13. The bottom frame 11 and the support plate 12 are fixedly connected by fasteners. The support plate 12 has a hinge clearance structure 14 near the edge of the folding side plate, which can be a rectangular hollow structure. Its size is adapted to the size of the hinge structure, so that the hinge is not disturbed during rotation. The hinge clearance structure 14 on the left side of the support plate 12 is adapted to the first fixed seat 71, and the hinge clearance structure 14 on the right side of the support plate 12 is adapted to the second fixed seat 73. The support plate 12 has installation clearance structures 15 at its four corners, which can be square hollow structures. This makes it inconvenient for the operator to put their hands into them during the assembly of the base 1, so as to facilitate the removal and placement.

[0057] In the above embodiment, the support limiting member 13 is fixedly installed at the four corners of the outer side of the bottom frame 11. The support limiting member 13 extends along the height direction of the box and is used to support the top cover 2. The support limiting member 13 has a right-angled baffle facing the inner side of the box and is used to limit the detachable side panel 3. The support limiting member 13 can be made of angle iron or other parts. The support limiting member 13 is installed vertically, and the opening structure formed by its two sides faces the inner side of the box. The extended lines of the sides of the four support limiting members 13 can form a rectangular structure to limit each box panel and prevent each box panel from falling off during transportation after folding or disassembling.

[0058] In some embodiments, refer to Figure 3 and Figure 5 The top cover 2 includes a top frame 21, a protective plate 22, and a second square annular pressure strip 23. The second square annular pressure strip 23 is located at the four edges of the inner side of the protective plate 22, and the top frame 21 is located on the outer side of the protective plate 22. The second square annular pressure strip 23, the protective plate 22, and the top frame 21 are connected by fasteners. The fasteners can be bolts or rivets. The second square annular pressure strip 23 can tightly press the edge of the protective plate 22 onto the top frame 21, enhancing the sealing performance of the top cover 2 and preventing moisture and dust from penetrating into the box through the top cover.

[0059] In some embodiments, refer to Figure 1 and Figure 2The outer sides of the first folding side panel 4 and the second folding side panel 5 are both provided with a sandwich structure 8 for placing documents. The sandwich structure 8 can be made of transparent acrylic material, and documents with cargo information can be placed inside the sandwich structure 8, making it easy for operators to identify the cargo contained in the box. It also has a waterproof and dustproof effect to prevent documents from getting dirty.

[0060] In the above embodiment, hooks 9 are provided on the two opposite side walls of the base 1. When the box is in a folded state, the hooks 9 can be used to tie the fixing rope to fix all the box panels and prevent them from falling apart during transportation.

[0061] The length, width, and height of the foldable logistics box are all between 800mm and 1500mm. Specifically, the dimensions of the foldable logistics box can be selected as 1100mm*1100mm*1062mm, and its specific dimensions can also be set according to actual needs. It can be shrunk or enlarged as a whole to adapt to the size of different goods.

[0062] The disassembly process of the folding logistics box in the above embodiment is as follows: First, remove the top cover; second, pull the pin to separate the folding side panel and the detachable side panel; third, flip the folding side panel outward at a certain angle so that the limiting groove structure no longer contacts the detachable side panel, at which point the two detachable side panels can be removed; fourth, fold the first folding side panel inward into the box and make it fit against the base, fold the second folding side panel inward into the box and make it fit against the first folding side panel, stack the two detachable side panels on the second folding side panel in sequence, and fasten the top cover onto the support limiting member of the base.
