Description

Technical Field

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

[0002] As a key carrier in the cargo transportation process, freight containers occupy a pivotal position in the global logistics system. Freight containers typically use a basic structure consisting of a bottom plate and four side panels to enclose the loading space, thus meeting the basic loading and transportation needs of goods.

[0003] Some of the freight containers currently in use have a rigid and stable structure, achieved by thermoforming the bottom plate and four side panels into a single unit. However, these containers have significant space redundancy issues when unloaded, as they cannot be folded or disassembled and require considerable storage and transportation space when stacked. Therefore, foldable freight containers have emerged on the market. However, current foldable freight containers are generally assembled by disassembling the side panels and then reassembling them using interlocking or snap-fitting methods, which is cumbersome and inconvenient to use.

[0004] Therefore, based on the above situation, we propose a multifunctional foldable cargo container to solve the above problems. Utility Model Content

[0005] This invention provides a multifunctional foldable cargo container to solve the problems in the prior art.

[0006] The technical problem solved by this utility model is achieved by the following technical solution:

[0007] A multifunctional foldable cargo container includes a bottom plate for supporting the bottom when loading goods, a first box plate arranged opposite each other, a second box plate arranged opposite each other, and a first locking member. Both first box plates are hinged to the bottom plate. The second box plate includes a first folding portion hinged to the bottom plate and two second folding portions respectively hinged to both ends of the first folding portion. The two second folding portions are respectively hinged to the two first box plates. The first locking member is used to restrict the first box plate to a vertical state on the bottom plate. When both the first box plate and the second box plate are in a vertical state, a space for holding goods is formed between them and the bottom plate.

[0008] Preferably, the first folding part and the base plate are provided with an expansion part located in the middle and a plug-in part that slides on both sides of the expansion part. The size of the placement space can be adjusted by changing the distance between the two plug-in parts.

[0009] Preferably, the expansion portion is provided with a second locking member, which is used to lock the position of the insertion portion.

[0010] Preferably, the base plate is provided with an extension portion, which is used to limit the first box plate to a vertical position.

[0011] Preferably, the bottom of the base plate is flush with the bottom of the expansion section.

[0012] The beneficial effects of this utility model are as follows: by hinged together the bottom plate, two first box plates and two second box plates, a space for holding goods is formed, and the first locking member locks it, which improves the overall stability. At the same time, the components are connected to each other, and whether folded or unfolded, it is an integral structure, which solves the problem of assembling each part of the box one by one in the prior art and improves the convenience of use.

Detailed Implementation

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0022] Reference Figures 1-6 As shown, a multifunctional foldable cargo container includes a base plate 1. Two first boxes 2 are hinged to two ends of the base plate 1, and the two first boxes 2 are arranged opposite each other. Two second boxes 3 are hinged to the other two ends of the base plate 1, and the two second boxes 3 are also arranged opposite each other. When the first boxes 2 and the second boxes 3 are both in a vertical state, they will form a space for holding goods between the base plate 1 and the base plate 1. The base plate 1 supports the bottom when loading goods, while the two first boxes 2 and the two second boxes 3 limit the goods to prevent them from spilling. Since the first boxes 2 and the second boxes 3 are both hinged to the base plate 1, a first locking member 4 is also provided to maintain the stability of the placement space. The first locking member 4 is used to restrict the first boxes 2 to a vertical state on the base plate 1 to prevent the first boxes 2 from rotating along the part where they are hinged to the base plate 1.

[0023] After the goods are unloaded, for easy storage and folding, the second box panel 3 includes a first folding part 31 hinged to the bottom plate 1 and two second folding parts 32 respectively hinged to both ends of the first folding part 31. The two second folding parts 32 are respectively hinged to the two first box panels 2. During folding, the first locking member 4 is released from its limiting position on the first box panel 2. Then, the first box panel 2, the first folding part 31, and the second folding parts 32 all rotate towards the center of the bottom plate 1. At the same time, the first box panel 2 rotates with the second folding part 32, and the first folding part 31 rotates synchronously with the second folding part 32. (e.g.) Figure 2 (As indicated by the arrow), after folding, the inner wall of the first box panel 2 is attached to the inner wall of the second folding part 32, the outer wall of the second folding part 32 is attached to the outer wall of the first folding part 31, and the inner wall of the first folding part 31 is attached to the inner wall of the bottom plate 1. After folding, from top to bottom, the components are the first box panel 2, the second folding part 32, the first folding part 31, and the bottom plate 1, making the whole panel flat. To achieve this folded state, the above hinge method can be implemented using hinges or other structures. In addition, the first box panel 2, the bottom plate 1, the first folding part 31, and the second folding part 32 can all be made of materials such as plastic or metal, and can be customized according to usage requirements. Since all components are connected, when unfolding, the two first box panels 2 are unfolded in a direction away from each other, causing the second folding part 32 and the first folding part 31 to unfold simultaneously. This solves the problem of assembling each component of the box one by one in the prior art, improving the convenience of use.

[0024] Reference Figures 1-3As shown, the first locking member 4 further includes a limiting strip 41 connected to the first box plate 2 and a limiting part 42 provided on the bottom plate 1. In use, the limiting strip 41 can be made of a tough metal, plastic or other materials. One end of the limiting strip 41 can be fixed to the first box plate 2 or rotatably connected to the first box plate 2. When the first box plate 2 and the second box plate 3 are unfolded and in a vertical state on the bottom plate 1, the limiting part 42 is inserted into the limiting hole 5 at the other end of the limiting strip 41. When there are few goods inside the box, due to the limiting of the first locking member 4, even if there is a collision between the boxes, the first box plate 2 and the second box plate 3 will not fold, so that the first box plate 2 and the second box plate 3 remain stable and reduce the damage to the goods caused by the movement of the first box plate 2 or the second box plate 3.

[0025] Among them, such as Figure 5 As shown, in order to restrict the degree of freedom of the first box panel 2 and the second box panel 3 when they are unfolded, an extension 9 is provided on the base plate 1. When the first box panel 2 is unfolded, the extension 9 resists the degree of freedom of rotation of the first box panel 2. When the outer wall of the first box panel 2 contacts the inner wall of the extension 9, the operator is prompted that the first box panel 2 is in a vertical state to avoid angular deviation caused by hinge gap or external force. The box body has been fully unfolded and the limiting part 42 can be inserted into the limiting hole 5.

[0026] Reference Figures 1-4 As shown, furthermore, in order to improve the functionality of the box, both the first folding part 31 and the bottom plate 1 are provided with an expansion part 6 located in the middle and a plug part 7 that slides into both sides of the expansion part 6. During use, the plug part 7 can be slid in and out of the expansion part 6 according to different transportation needs, thereby changing the distance between the two plug parts 7. When the distance between the two plug parts 7 is small, the capacity inside the box is small. When the distance between the two plug parts 7 is large, the capacity inside the box is large. The position of the plug part 7 is fixed by the sliding resistance, further improving the functionality of the box.

[0027] In order to further lock the position of the plug-in part 7, the expansion part 6 is provided with a second locking member 8. The second locking member 8 can be a simple structure such as a screw. For example, when the second locking member 8 is a screw, after the capacity of the box is adjusted, the screw is turned so that one end of the screw tightly abuts against the plug-in part 7, thereby fixing the position of the plug-in part 7. In actual use, although it is necessary to lock the position of the plug-in part 7, this step is adjusted according to the usage requirements of the goods before loading. Moreover, the transportation process of a batch of goods may require multiple transportations, while the capacity of the box only needs to be adjusted once, which will not affect the convenience of folding, storing and unfolding the box.

[0028] Reference Figures 1-4 As shown, furthermore, in order to maintain the stability of the box, the bottom of the bottom plate 1 is flush with the bottom of the expansion section 6. The flush bottom surface can increase the contact area between the box and the ground. When encountering bumps during transportation, the impact force is transmitted to the box structure synchronously through the entire bottom surface, rather than being concentrated on one side of the bottom plate 1 or the expansion section 6.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
