Description

Technical Field

[0001] This application relates to the field of container technology, and more particularly to a detachable container. Background Technology

[0002] Container shipping is an important mode of transport in the multimodal transport of goods in international trade. It has the advantage of high standardization and greatly improves the convenience of goods transportation.

[0003] However, during transportation, shipping containers are frequently subjected to complex external forces and rain erosion due to road and sea conditions, posing various challenges to their load-bearing capacity and sealing. Deformation, collapse, or leakage of the container can threaten cargo transportation safety and directly cause economic losses. Currently, the bottom beams of shipping containers are weak, and their waterproofing performance is generally poor.

[0004] Furthermore, due to trade imbalances, empty containers may return on certain routes, leading to resource waste and increased transportation costs, especially when transporting small batches or low-value goods, where the cost advantage is not obvious. Although container handling is highly mechanized, its non-detachable nature makes it less adaptable to different types of goods in some situations, failing to meet the transportation needs of certain special cargoes. It is also less flexible in transporting oversized or overweight goods, potentially leading to a waste of transportation resources.

[0005] It is evident that existing containers suffer from problems such as weak load-bearing capacity, poor waterproofing, and empty container return trips, resulting in high transportation costs and resource waste. Utility Model Content

[0006] To address at least one of the aforementioned technical problems, this application provides a detachable container. By setting up high bottom beams to increase the load-bearing capacity and stability of the container, by setting up waterproof side panels and sealing structures to improve the waterproof capability of the container, and by setting up a detachable container structure to improve the container's cargo adaptability and transportation flexibility, transportation costs are reduced.

[0007] Therefore, this application provides a detachable container, including a bottom plate, a top plate, a left side plate, a right side plate, a front frame, and a rear frame that are movably connected; the bottom plate includes symmetrically arranged bottom beams, the left side plate and the right side plate are respectively fixed on the bottom beams, and the two ends of the bottom beams are detachably connected to the front frame and the rear frame respectively through connecting parts, wherein the height of the bottom beams is set to 350-650mm; the top plate is provided with a waterproof edge and a sealing structure, the waterproof edge is provided on both sides of the top plate and is arranged parallel to the left side plate and the right side plate respectively; the sealing structure is provided at the connection between the top plate and the front frame and the rear frame; wherein, the sealing structure includes a water baffle and a sealing strip, the water baffle has a water-blocking folded edge, and the sealing strip is fitted with the water-blocking folded edge; the water baffle is respectively fixed on the front frame and the rear frame.

[0008] In this implementation, the 350-650mm high bottom beam effectively enhances the load-bearing capacity of the bottom plate, allowing for load-bearing requirements of over 30 tons of cargo without welding, simply through bolt connections. It also facilitates the overall disassembly of the container. Waterproofing at the top plate is achieved through waterproof side panels and a sealing structure. The waterproof side panels improve the waterproofing performance of the top side panels, while the sealing structure enhances the waterproofing performance between the front and rear frames and the top plate. In this embodiment, all bolt connections are completed inside the container, ensuring that the container cannot be opened externally without force, thus enhancing its security and anti-theft capabilities.

[0009] In one implementation, the connecting part includes a corner piece and a pin, the corner piece being bolted to the front frame / rear frame, and the pin being movably connected to the upright of the front frame / rear frame.

[0010] This method involves securing the corner brackets and uprights with bolts before using pins for better connection. Furthermore, the pin connection allows for more even distribution of external forces within the enclosure, preventing stress concentration.

[0011] In one implementation, corner pieces are located at the four corners of the front / rear frame and are fixedly connected to the bottom beam and top plate, respectively.

[0012] This implementation method sets corner brackets at the connection points of the front and rear frames with the bottom beam and top plate, and connects the front frame, rear frame, bottom beam and top plate by a combination of bolts and pins, which enhances the structural strength and load-bearing capacity of the connection points and effectively avoids stress concentration.

[0013] In one implementation, both the corner piece and the upright have fixing holes for inserting pins.

[0014] To facilitate the installation of the pin and make it easier for workers to operate, this implementation method involves making fixing holes in the column and corner fittings. The pin can be directly fixed in the fixing holes and can be secured with cotter pins to prevent it from coming out of the fixing holes.

[0015] In one implementation, the connecting parts are fixedly installed at the four corners of the front / rear frame, and the connecting parts are bolted to the bottom beam and the top plate.

[0016] This implementation method sets up connecting parts at the connection points between the front and rear frames and the bottom beam and top plate, and connects the front frame, rear frame, bottom beam and top plate by bolt connection, which enhances the structural strength and load-bearing capacity of the connection and effectively avoids stress concentration.

[0017] In one implementation, the connecting part includes a connecting plate, which is fixedly installed at the four corners of the front frame / rear frame and bolted to the bottom beam and top plate; wherein, the connecting plate and the bottom beam and top plate are provided with a plurality of first bolt holes, and the number and position of the plurality of first bolt holes on the connecting plate and the bottom beam and top plate are matched.

[0018] This implementation fixes the connecting plate at the four corners of the front and rear frames, making it easy to align with the bottom beam and top plate. Multiple first bolt holes are provided on the connecting plate and the bottom beam and top plate to be used for multiple bolt connections. Using multiple bolt connections can improve the connection stability.

[0019] In one implementation, the connecting part further includes a reinforcing plate, which is bolted to the connecting plate, the bottom beam, and the top plate; the reinforcing plate has a plurality of second bolt holes, the number and position of which match the first bolt holes on the connecting plate, the bottom beam, and the top plate.

[0020] In this implementation, by adding bolted connections between the reinforcing plate and the connecting plate, bottom beam, and top plate, the connection strength of the connecting plate, bottom beam, and top plate can be improved, thereby enhancing the connection stability between the front and rear frames and the bottom beam and top plate.

[0021] In one implementation, the bottom beam is an I-beam.

[0022] This implementation method uses I-beams for the bottom beam, which effectively improves the load-bearing capacity of the bottom plate. It eliminates the need for welding, allowing for bolted connections to meet load-bearing requirements of over 30 tons. It boasts strong load-bearing capacity and high stability.

[0023] In one implementation, the top plate is fixed to the left and right side plates by fasteners, wherein the fasteners are fixed to the left / right side plates.

[0024] This implementation method uses a snap-fit ​​connection between the top plate and the left side plate, as well as the top plate and the right side plate, to achieve a detachable connection between the top plate and the left and right side plates, thereby achieving overall detachability and strong adaptability to goods and transportation flexibility.

[0025] In one implementation, in the usage state, the bottom plate, top plate, left side plate, right side plate, front frame, and rear frame form a closed space for loading goods; in the non-use state, the front frame, rear frame, top plate, left side plate, and right side plate are stacked sequentially on the bottom plate, and the front frame, rear frame, top plate, left side plate, and right side plate are detachably connected to the bottom plate through movable connectors.

[0026] This implementation improves the container's cargo adaptability and transportation flexibility by using a detachable container structure. In use, the bottom, top, left, right, front, and rear frames form a sealed space for loading goods. For empty container return trips, the front, rear, top, left, and right frames can be stacked sequentially on the bottom. Multiple containers can be folded and stacked for empty container transport. This not only saves space but also reduces transportation costs and minimizes resource waste.

[0027] Compared with existing technologies, the detachable container provided in this application offers the following advantages: This application increases the container's load-bearing capacity and stability by setting a high bottom beam; improves the container's waterproof capability by setting waterproof side panels and a sealing structure; and enhances the container's cargo adaptability and transportation flexibility by setting a detachable container structure, thereby reducing transportation costs. In use, the bottom plate, top plate, left side plate, right side plate, front frame, and rear frame form a sealed space for loading goods. When returning empty, the front frame, rear frame, top plate, left side plate, and right side plate can be stacked sequentially on the bottom plate. Multiple containers can be folded and stacked for empty container transport, achieving a multi-functional solution. This not only saves space but also reduces transportation costs and minimizes resource waste. It solves the resource waste problems caused by weak load-bearing capacity, poor waterproof performance, and empty container return trips in existing technologies.

[0043] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0044] In the description of this application, the terms “center,” “upper,” “lower,” “front,” “rear,” “left,” “right,” “vertical,” “horizontal,” “top,” “bottom,” “inner,” and “outer,” etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0045] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation", "connection" and "joining" should be interpreted broadly, for example, they can be fixed connections, detachable connections, mating connections or integral connections; those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0046] In the description of this specification, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments.

[0047] During transport, shipping containers are frequently subjected to complex external forces and rain erosion due to road and sea conditions, posing various challenges to their load-bearing capacity and sealing. Deformation, collapse, or leakage of the container can threaten cargo safety and directly cause economic losses. Currently, the bottom beams of containers are weak, and their waterproofing performance is generally inadequate. Furthermore, due to trade imbalances, empty containers may be returned on certain routes, leading to resource waste and increased transportation costs, especially when transporting small batches or low-value goods, where cost advantages are not significant. Although container loading and unloading are highly mechanized, their non-detachable nature makes them less adaptable to certain types of cargo, failing to meet the needs of transporting specific goods. They are also inflexible in transporting oversized or overweight cargo, potentially leading to a waste of transportation resources.

[0048] This shows that existing containers suffer from resource waste during transportation due to factors such as weak load-bearing capacity, poor stability, poor waterproof performance, and empty container return trips.

[0049] Therefore, to solve the above problems, this application provides a detachable container. By setting up a high-bottom beam 610 to increase the container's load-bearing capacity and stability, by setting up a waterproof side panel 101 and a sealing structure to improve the container's waterproof capability, and by setting up a detachable container structure to improve the container's cargo adaptability and transportation flexibility, thereby reducing transportation costs. When returning empty, multiple containers can be folded and stacked for transport using a single empty container, saving space, reducing transportation costs, and minimizing resource waste.

[0050] like Figure 1-9 As shown, this application provides a detachable container, including a bottom plate 600, a top plate 100, a left side plate 200, a right side plate 300, a front frame 400, and a rear frame 500 that are movably connected. The bottom plate 600 includes symmetrically arranged bottom beams 610. The left side plate 200 and the right side plate 300 are respectively fixed to the bottom beams 610. The two ends of the bottom beams 610 are detachably connected to the front frame 400 and the rear frame 500 through connecting parts 620, respectively. The height of the bottom beams 610 is set to 350-650mm. The top plate 100 is provided with a waterproof edge plate 101 and a sealing structure. The waterproof edge plate 101 is provided on both sides of the top plate 100 and is arranged parallel to the left side plate 200 and the right side plate 300, respectively. The sealing structure is provided at the connection between the top plate 100 and the front frame 400 and the rear frame 500. The sealing structure includes a water baffle 102 and a sealing strip 103. The water baffle 102 has a water-blocking folded edge, and the sealing strip 103 is fitted to the water-blocking folded edge. The water baffle 102 is fixed to the front frame 400 and the rear frame 500 respectively.

[0051] Specifically, in this embodiment, the bottom beam 610 with a height of 350-650mm effectively enhances the load-bearing capacity of the bottom plate 600, allowing it to meet the load-bearing requirements of over 30 tons of cargo without welding, simply by bolting connections. It also facilitates the overall disassembly of the container. Waterproofing at the top plate 100 is achieved through the waterproof side panel 101 and the sealing structure. The waterproof side panel 101 improves the waterproofing performance of the top of the side panels, and the sealing structure improves the waterproofing performance between the front and rear frames and the top plate 100.

[0052] Typically, existing container bottom beams 610 are relatively low, with their upper surface flush with the container's bottom plate 600. The left side plate 200 and right side plate 300 are fixedly connected to the bottom beam 610. In this structure, if the container shakes or tilts during transport, the weight of the cargo inside the container directly presses on the side plates, resulting in significant pressure and making them highly susceptible to deformation. If the side plate structure is not strong enough, or if the impact force of the cargo on the side plates exceeds their load-bearing capacity, it can lead to side plate deformation or even container disintegration.

[0053] In this embodiment, bottom beams 610 are disposed on both sides of the bottom plate 600. Exemplarily, the bottom beams 610 can be disposed along the length of the container. The bottom beams 610 are high bottom beams, meaning their height is greater than the plane of the bottom plate 600 used for loading cargo. When the container shakes or tilts during transportation, the weight of the cargo is distributed between the bottom beams 610 and the side plates. Since the bottom beams 610 and the bottom plate 600 are rigidly connected, the bottom beams 610 can withstand greater impact forces from the cargo. Most of the impact force of the cargo on the side plates is borne by the bottom beams 610, thus reducing the impact force borne by the side plates. This significantly reduces the deformation of the side plates, effectively preventing side plate deformation or container disintegration, thereby improving the container's load-bearing capacity and stability.

[0054] To improve the waterproof performance of the container, a waterproof edge plate 101 is provided at the edge of the top plate 100 in this embodiment. The waterproof edge plate 101 is provided along the length of the container and is fixedly installed at the edge of the top plate 100. The waterproof edge plate 101 is parallel to the left side plate 200 and the right side plate 300, and has gaps between them. The waterproof edge plate 101 can be fixedly connected to the top plate 100 by welding. After the top plate 100 and the left and right side plates are installed, the waterproof edge plate 101 can cover part of the left and right side plates, that is, the waterproof edge plate 101 covers the connection between the top plate 100 and the left and right side plates. Since the top plate 100 is movably connected to the left and right side plates, the waterproof performance at this connection is poor. Using the waterproof edge plate 101 to cover the connection between the top plate 100 and the left and right side plates can significantly improve the waterproof performance of the container and provide strong splash resistance.

[0055] In addition, a sealing structure is provided at the connection between the top plate 100 and the front and rear frames. For example, the sealing structure includes a water baffle 102 and a sealing strip 103. The water baffle 102 has a water-blocking folded edge, and the sealing strip 103 is fitted into the water-blocking folded edge. The water baffle 102 is fixed to the front frame 400 and the rear frame 500, respectively.

[0056] like Figure 3 As shown, the baffle 102 has a bend, with one end fixed to the front frame 400 or the rear frame 500, and the other end has a folded edge that serves as a water-blocking edge. The water-blocking edge can be integrally formed with the baffle 102, or it can be combined using welding or bonding. A sealing strip 103 is located at the water-blocking edge and can be fitted snugly to improve the sealing effect. A square tube is provided along the edge of the top plate 100. When the top plate 100 is connected to the front frame 400 / rear frame 500, the square tube presses down on the sealing strip 103, strengthening the sealing ability between the square tube and the front frame 400 / rear frame 500, thereby improving the waterproof capability between the top plate 100 and the front frame 400 / rear frame 500, and significantly enhancing the splash-proof capability.

[0057] In this embodiment, the bottom plate 600, top plate 100, left side plate 200, right side plate 300, front frame 400, and rear frame 500 are all detachably connected. In use, these components form a sealed space for loading goods. During the return trip with an empty container, the front frame 400, rear frame 500, top plate 100, left side plate 200, and right side plate 300 can be stacked sequentially on the bottom plate 600. Multiple containers can be folded and stacked for transport with a single empty container, improving the container's cargo adaptability and transport flexibility, and reducing transportation costs.

[0058] Compared with existing technologies, this embodiment increases the load-bearing capacity and stability of the container by setting a high bottom beam 610, improves the waterproof capability of the container by setting a waterproof side plate 101 and a sealing structure, and enhances the cargo adaptability and transportation flexibility of the container by setting a detachable container structure, thereby reducing transportation costs. In use, the bottom plate 600, top plate 100, left side plate 200, right side plate 300, front frame 400, and rear frame 500 form a sealed space for loading goods. When returning empty, the front frame 400, rear frame 500, top plate 100, left side plate 200, and right side plate 300 can be stacked sequentially on the bottom plate 600. Multiple containers can be folded and stacked for empty container transport, achieving a multi-functional solution. This not only saves space but also reduces transportation costs and minimizes resource waste. It solves the resource waste problems caused by weak load-bearing capacity, poor waterproof performance, and empty container return trips in existing technologies.

[0059] In one embodiment, the connecting part 620 includes a corner piece 621 and a pin 622. The corner piece 621 is bolted to the front frame 400 / rear frame 500, and the pin 622 is movably connected to the column of the front frame 400 / rear frame 500.

[0060] like Figure 4 As shown, the corner fitting 621 can be a general-purpose corner fitting for containers, with a structure similar to the corner fitting 621 in the invention module of CN104417964A, entitled "Segmented Assembled Container, Manufacturing, Stacking and Transportation Method and Finished Product Module", which has a detailed description, and will not be elaborated further in this application.

[0061] In this embodiment, corner bracket 621 can be bolted to the front frame 400 / rear frame 500 to achieve a detachable connection between corner bracket 621 and the front frame 400 / rear frame 500. The difference between this embodiment and the prior art is that after corner bracket 621 is bolted to the front frame 400 / rear frame 500, a pin 622 is used to fix corner bracket 621 to the front frame 400 / rear frame 500. The pin 622 makes the connection between corner bracket 621 and the front frame 400 / rear frame 500 more stable and improves the connection effect. Furthermore, the pin 622 connection allows for more even distribution of external forces across the container, avoiding stress concentration. Therefore, this embodiment can significantly reduce stress concentration in the container, preventing structural failure and cracking due to stress concentration, and improving the container's load-bearing capacity.

[0062] In this embodiment, the corner piece 621 is connected to the uprights of the front frame 400 / rear frame 500, making installation convenient.

[0063] In one embodiment, corner fittings 621 are disposed at the four corners of the front frame 400 / rear frame 500 and are fixedly connected to the bottom beam 610 and the top plate 100, respectively. Since the container is rectangular in shape and has eight corners in total, corner fittings 621 need to be provided at the connection points between the front and rear frames and the top plate 100 and the bottom plate 600. That is, four corner fittings 621 are provided at the four corners of the front frame 400 and four corner fittings 621 are provided at the four corners of the rear frame 500 to facilitate the connection between the top plate 100 and the bottom plate 600.

[0064] In this embodiment, corner brackets 621 are provided at the connection points of the front and rear frames with the bottom beam 610 and the top plate 100, and the front frame 400, rear frame 500, bottom beam 610 and top plate 100 are connected by bolts and pins 622, which enhances the structural strength and load-bearing capacity of the connection points and effectively avoids stress concentration.

[0065] In one embodiment, both the corner piece 621 and the column are provided with fixing holes for inserting pins 622.

[0066] As mentioned earlier, to facilitate the installation of the latch 622 and make it easier for workers to operate, fixing holes are made on the upright and corner fitting 621. The latch 622 can be directly fixed in the fixing holes, and can be secured with cotter pins to prevent it from coming out of the fixing holes. This makes it very convenient for workers to install or remove the latch 622; they only need to remove the cotter pins to pull it out. This significantly improves work efficiency during container assembly.

[0067] In one embodiment, the connecting part 620 is fixedly disposed at the four corners of the front frame 400 / rear frame 500, and the connecting part 620 is bolted to the bottom beam 610 and the top plate 100.

[0068] In one embodiment, the front frame 300 and the rear frame 400 can also be disassembled; for example, the pillar and the door panel can be detachably connected. Figure 1 As shown, the front frame 300 includes a pillar and a door panel, which are bolted together. The pillar is bolted to the connecting part 620. Similarly, the rear frame 400 includes detachably connected left and right door assemblies, which include detachably connected pillars and door panels, with the pillars bolted to the connecting part 620.

[0069] like Figure 2 As shown, this embodiment differs from the corner piece 621 connection described above. Connecting portions 620 are provided at the four corners of the front frame 400 and rear frame 500. These connecting portions 620 are plate-like structures that can be welded and fixed to the columns of the front frame 400 and rear frame 500. During connection, the connecting portions 620 are aligned with the bottom beam 610 and top plate 100, and then fixed together with bolts. It is understood that, to facilitate bolt connection, threaded holes or through holes can be provided at corresponding positions on the connecting portions 620, the bottom beam 610, and the top plate 100.

[0070] In this embodiment, a connecting part 620 is provided at the connection between the front and rear frames and the bottom beam 610 and the top plate 100, and the front frame 400, the rear frame 500, the bottom beam 610 and the top plate 100 are connected by bolts, which enhances the structural strength and load-bearing capacity of the connection and effectively avoids stress concentration.

[0071] In one embodiment, the connecting part 620 includes a connecting plate 623, which is fixedly disposed at the four corners of the front frame 400 / rear frame 500 and bolted to the bottom beam 610 and the top plate 100. The connecting plate 623, the bottom beam 610, and the top plate 100 are all provided with a plurality of first bolt holes 625, and the number and position of the plurality of first bolt holes 625 on the connecting plate 623, the bottom beam 610, and the top plate 100 are matched.

[0072] In this embodiment, the connecting plate 623 is fixed at the four corners of the front and rear frames to facilitate alignment with the bottom beam 610 and the top plate 100. Multiple first bolt holes 625 are provided on the connecting plate 623, the bottom beam 610, and the top plate 100 for multiple bolt connections. Using multiple bolt connections can improve the connection stability.

[0073] In one embodiment, the connecting portion 620 further includes a reinforcing plate 624, which is bolted to the connecting plate 623, the bottom beam 610, and the top plate 100. The reinforcing plate 624 has a plurality of second bolt holes 626, the number and position of which match the first bolt holes 625 on the connecting plate 623, the bottom beam 610, and the top plate 100.

[0074] In this embodiment, by adding a reinforcing plate 624 and bolting it to the connecting plate 623, the bottom beam 610, and the top plate 100, the connection strength of the connecting plate 623, the bottom beam 610, and the top plate 100 can be improved, thereby improving the connection stability between the front and rear frames and the bottom beam 610 and the top plate 100.

[0075] In one embodiment, the bottom beam 610 is an I-beam.

[0076] In this embodiment, the bottom beam 610 uses I-beams, which effectively enhances the load-bearing capacity of the bottom plate 600. It can meet the load-bearing requirements of over 30 tons of cargo by bolting without welding. It boasts strong load-bearing capacity and high stability.

[0077] In one embodiment, the top plate 100 is fixed to the left side plate 200 and the right side plate 300 by a fastener 700, wherein the fastener 700 is fixedly disposed on the left side plate 200 / right side plate 300.

[0078] To achieve waterproofing, existing shipping containers typically weld the top panel 100 to the left side panel 200 and right side panel 300 together, making them non-removable, hindering flexible transport, and resulting in high transportation costs. However, this application incorporates a waterproof side panel 101 and a sealing structure, allowing the top panel 100 and side panels to be detachably connected, enabling flexible transport and reducing costs.

[0079] Specifically, such as Figure 7-9 As shown, the latch 700 can be configured as a bent plate 701 and a fixing plate 702. The fixing plate 702 can be fixed to the top plate 100 or the side plate, and the bent plate 701 can be fixed to the side plate or the top plate 100. The two are connected by bolts to achieve a detachable connection between the top plate 100 and the side plate. The installation or disassembly process is simple and efficient.

[0081] In one embodiment, in the usage state, the base plate 600, top plate 100, left side plate 200, right side plate 300, front frame 400, and rear frame 500 form a sealed space for loading goods. In the non-use state, the front frame 400, rear frame 500, top plate 100, left side plate 200, and right side plate 300 are stacked sequentially on the base plate 600, and the front frame 400, rear frame 500, top plate 100, left side plate 200, and right side plate 300 are detachably connected to the base plate 600 via movable connectors.

[0082] This embodiment improves the cargo adaptability and transportation flexibility of the container by setting a detachable box structure. In use, the bottom plate 600, top plate 100, left side plate 200, right side plate 300, front frame 400, and rear frame 500 form a closed space for loading goods. When returning empty, the front frame 400, rear frame 500, top plate 100, left side plate 200, and right side plate 300 can be stacked sequentially on the bottom plate 600. Multiple containers can be folded and stacked for transport using a single empty container. This embodiment enables four-in-one transportation, such as... Figure 10-11 As shown, the three containers are disassembled, and the components are stacked into one container for transportation. One container carries three containers, which not only saves space but also reduces transportation costs and minimizes resource waste.

[0083] In summary, the detachable container provided in this application meets the ISO requirements for general cargo containers, including a movable bottom plate structure, a top plate module, a left side plate module, a right side plate module, a front frame module, and a rear frame module. The top plate module, left side plate module, right side plate module, front frame module, and rear frame module are all standard modules in the container industry and are replaceable. This will greatly save on maintenance costs in the future. The container can also be disassembled into individual modules and placed into other containers to save on return shipping costs.

[0084] This embodiment of the application increases the load-bearing capacity and stability of the container by setting a high bottom beam 610, improves the waterproof capability of the container by setting a waterproof side plate 101 and a sealing structure, and improves the cargo adaptability and transportation flexibility of the container by setting a detachable container structure, thereby reducing transportation costs. In the use state, the bottom plate 600, top plate 100, left side plate 200, right side plate 300, front frame 400 and rear frame 500 form a closed space for loading goods. When returning empty, the front frame 400, rear frame 500, top plate 100, left side plate 200 and right side plate 300 can be stacked on the bottom plate 600 in sequence. After multiple containers are folded and stacked, they can be transported empty, achieving the purpose of multiple uses in one. This not only saves space, but also reduces transportation costs and minimizes resource waste. It solves the resource waste problems caused by weak load-bearing capacity, poor waterproof performance and empty return trips in the prior art.
