Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of logistics transportation equipment, in particular to a lightweight recyclable container with a detachable structure. BACKGROUND

[0002] As an important carrier of modern logistics transportation, the structural performance of the container directly affects the transportation efficiency and cost. The existing container is usually welded by all-steel corrugated plates. Although this structure ensures the overall strength of the container body, it also leads to a large self-weight of the container. In the process of long-distance transportation, the excessive self-weight not only increases the fuel consumption of the transportation vehicle, but also occupies the effective cargo loading quota, which is difficult to meet the urgent needs of energy saving and emission reduction and lightweight of the current green logistics.

[0003] In terms of cargo loading and unloading operations, most traditional containers are only provided with a pair of opposing doors at the tail of the container body, and the loading and unloading of goods must follow a strict sequence. When a specific cargo located in the deep part of the container body needs to be accessed, the external cargo often needs to be removed first. This operation mode limits the flexibility of loading and unloading, prolongs the material turnover time, and reduces the operation efficiency of the logistics transfer station. Although some containers attempt to open side doors, most of them are heavy and rigid door plate structures, which occupy a large space and are inconvenient to operate.

[0004] In order to facilitate the recycling of empty containers and reduce transportation costs, detachable containers have gradually attracted attention. However, the existing detachable containers mostly use simple bolts to directly connect the rod members when assembling the frame. This connection method is prone to stress concentration at the connection nodes when facing bumps and vibrations during transportation, heavy pressure or lateral wind load. Long-term dynamic load will cause the connection points to loosen, deform or even break, and lack effective torsional structure, which makes the overall rigidity of the frame insufficient, seriously affecting the service life and transportation safety of the container.

[0005] Therefore, the present application provides a lightweight recyclable container with a detachable structure to solve the problems of the prior art. SUMMARY

[0010] Preferably, the first connecting component includes a first pin, which is disposed on the outer side of the second baffle. A first locking block is fixedly connected to the outer side of the second support plate. The first locking block passes through the first skin and is slidably connected to the middle of the second baffle. The insertion rod of the first pin is slidably connected to the middle of the first locking block.

[0011] Preferably, the second connecting component includes two second pins, which are respectively fixedly connected to the outer sides of the two second plates. The outer sides of the two first plates are each fixedly connected to a second block, and the inserts of the two second pins are respectively slidably connected to the middle of the two second blocks.

[0012] Preferably, the fixing assembly includes a plurality of first inserts, which are respectively fixedly connected to the upper and lower ends of a plurality of uprights.

[0017] This invention provides a lightweight, recyclable container with a detachable structure. It offers the following advantages: 1. This invention uses flexible skin combined with multi-level support plates to construct wall panel components, replacing the traditional all-steel corrugated structure and reducing the overall weight of the container. The inner and outer skins are fastened to the internal support frame with screws to form a composite wall structure. This significantly reduces the weight of the container while ensuring sufficient impact resistance and planar stiffness of the side walls, effectively resolving the contradiction between lightweight design and structural strength requirements.

[0018] 2. This invention utilizes movable components to construct a side-folding storage mechanism. A sliding plate along a track causes the support plate to converge, pulling the flexible skin to fold and deform, achieving a large-span opening of the container's sidewalls. This overcomes the limitation of traditional containers that can only be operated through the tailgate, allowing loading and unloading equipment to directly access goods deep within the container from the side, significantly shortening the loading and unloading path and time, and improving the efficiency of logistics transshipment.

[0019] 3. This invention employs a multi-directional plug-in connection with bolt locking, effectively dispersing shear stress transmitted through the nodes by utilizing the large-area contact between the plug and the slot. Combined with the mechanical engagement of the limiting groove and the limiting block, the torsional freedom of the frame members is restricted, improving the overall rigidity and torsional load resistance of the frame nodes in dynamic transportation environments. This avoids connection breakage or failure caused by localized stress concentration, extending the service life of the enclosure. Attached Figure Description

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Reference Appendix Figure 1 Appendix Figure 2 Appendix Figure 4 Appendix Figure 5 and attached Figure 9 This embodiment provides a lightweight recyclable container with a detachable structure, including a frame assembly. The frame assembly includes multiple corner blocks 1, uprights 2, longitudinal bars 3, and transverse bars 4. A fixed component is provided in the middle of each of the multiple corner blocks 1. A wall panel assembly is provided between two adjacent transverse bars 4 and two adjacent uprights 2. A movable component is provided on the side of the multiple transverse bars 4 near the wall panel assembly. The wall panel assembly includes a first skin 8, a second skin 17, and a support assembly. The first skin 8 and the second skin 17 are both located in the middle of the movable assembly. A second support plate 23, a plurality of third support plates 24, a plurality of fourth support plates 25, and a first support plate 22 are sequentially arranged between the first skin 8 and the second skin 17. Screws 21 are provided in the middle of the plurality of third support plates 24 and the plurality of fourth support plates 25. The first skin 8 and the second skin 17 are connected to the second support plate 23, the plurality of third support plates 24, and the plurality of fourth support plates 25 by screws 21. The second support plate 23, the first support plate 22, the first skin 8, and the second skin 17 are connected to the frame assembly by the support assembly.

[0024] In one specific embodiment, the frame assembly serves as the main skeleton of the container, bearing the main stacking load and transportation stress; the wall panel assembly serves as the side enclosure structure, achieving lightweight while ensuring strength through a multi-layer composite design; the movable assembly provides guidance and support paths for the folding and storage of the wall panels, realizing the side opening function; and the fixed assembly is responsible for the connection and locking of the frame nodes, dispersing the node stress through plug-in cooperation. Both the first skin 8 and the second skin 17 are made of flexible composite materials, selected from thermoplastic polyurethane-coated high-strength industrial fabric, polyvinyl chloride-coated polyester fiber cloth, or aramid fiber-reinforced rubber composite cloth. They possess high tensile strength and high tear strength, resisting wind and rain erosion and external impacts during transportation. This replaces traditional corrugated steel plates, reducing the box's weight. The second support plate 23, third support plate 24, fourth support plate 25, and first support plate 22 form a skeletal support within the skin. Screws 21 are used to lock the first skin 8, second skin 17, second support plate 23, third support plate 24, and fourth support plate 25 together, forming a composite wall with a certain rigidity, preventing the first skin 8 and second skin 17 from bulging or denting during transportation.

[0025] Reference Appendix Figure 3 and attached Figure 7 The support assembly includes two fixing plates 19, which are fixedly connected to the outer sides of two of the uprights 2 respectively. The first skin 8, the second skin 17 and the first support plate 22 are connected to the fixing plates 19 by bolts. The outer sides of the other two uprights 2 are fixedly connected to a first baffle 18 and a second baffle 30. The second support plate 23 is slidably connected between the first baffle 18 and the second baffle 30. A first connecting assembly is provided between the second baffle 30 and the second support plate 23.

[0026] In one specific embodiment, the fixing plate 19 rigidly anchors one end of the wall panel, i.e., the end where the first support plate 22 is located, to the upright 2, forming the fixed starting end of the wall panel. On the opposite side of the upright 2, the first baffle 18 and the second baffle 30 form a limiting slide, and the second support plate 23, as the moving end of the wall panel, slides into the slide for fixation. Through the connection method of fixing one end and sliding the other end, when the wall panel assembly is pulled by an external force, it can drive the second support plate 23 to move along the length direction of the frame with the fixing plate 19 as a reference, thereby realizing the unfolding and folding operation of the first skin 8 and the second skin 17.

[0027] Reference Appendix Figure 6 and attached Figure 11 The active components include multiple third plates 16, which are fixedly connected to the side of multiple crossbars 4 near the first skin 8. Hinges 27 are fixedly connected to the outer sides of multiple uprights 2. Two second plates 10 and two first plates 7 are fixedly connected to the outer sides of the multiple hinges 27. Slide plates 20 are fixedly connected to the upper and lower ends of the second support plate 23, multiple third support plates 24, multiple fourth support plates 25 and the first support plate 22. A pulley 15 is provided in the middle of the slide plate 20. A groove 28 is provided in the middle of the multiple third plates 16, the first plates 7 and the second plates 10. The slide plate 20 is slidably connected in the middle of the groove 28. Second connecting components are provided on the outer sides of the multiple first plates 7 and the second plates 10. A water channel 29 is provided at the bottom of the two second plates 10 and the two first plates 7 to drain the water accumulated in the third plates 16, the second plates 10 and the first plates 7.

[0028] In one specific embodiment, the movable components constitute a guide rail system for the folding of the wall panel. The third card plate 16, the second card plate 10, and the first card plate 7 are assembled together to form a complete horizontal track. The grooves 28 opened in the third card plate 16, the second card plate 10, and the first card plate 7 provide a movement path for the sliding plate 20. When it is necessary to open the side of the container, the sliding plate 20 rolls in the grooves 28 using pulleys 15, reducing frictional resistance and allowing the second support plate 23, multiple third support plates 24, and multiple fourth support plates 25 to slide smoothly and move closer together, driving the flexible first skin 8 and the second skin 17 to fold and store. This eliminates spatial obstruction during unloading and facilitates direct side operation. The hinge 27 allows the first card plate 7 and the second card plate 10 to rotate outward, so that when the third support plate 24 and the fourth support plate 25 are damaged by external impact, they can be replaced locally, avoiding the waste caused by replacing the whole, and realizing recycling. The water channel 29 uses the principle of gravity to drain the water accumulated in the track, preventing long-term water accumulation from causing component corrosion or pulley jamming.

[0029] Reference Appendix Figure 7The first connecting component includes a first pin 13, which is disposed on the outer side of the second baffle 30. A first locking block 26 is fixedly connected to the outer side of the second support plate 23. The first locking block 26 passes through the first skin 8 and is slidably connected to the middle of the second baffle 30. The insertion rod of the first pin 13 is slidably connected to the middle of the first locking block 26.

[0030] In one specific embodiment, the first connecting component acts as a lock to prevent the moving end of the wall panel. When the wall panel is fully extended, i.e., the container is closed, the first locking block 26 on the second support plate 23 moves to a predetermined locking position. At this time, the first pin 13 is inserted into the hole of the first locking block 26, creating mechanical interference. This structure restricts the horizontal freedom of the second support plate 23, preventing the wall panel from accidentally sliding open due to vehicle bumps or cargo impacts during transportation, thus ensuring the container's sealing.

[0031] Reference Appendix Figure 8 The second connecting component includes two second pins 14, which are fixedly connected to the outer sides of the two second plates 10 respectively. The outer sides of the two first plates 7 are fixedly connected to second blocks 31 respectively. The inserts of the two second pins 14 are slidably connected to the middle of the two second blocks 31 respectively.

[0032] In one specific embodiment, the second connecting assembly is used to maintain the straightness and rigidity of the track. Since the first locking plate 7 and the second locking plate 10 are connected by a hinge 27, they can rotate relative to each other in the unlocked state. By inserting the second pin 14 into the second locking block 31, the two independent locking plates are rigidly connected at the joint, eliminating the rotational freedom at the hinge. This ensures that the slide 28 remains straight and aligned during the sliding of the wall panel, preventing the slide plate 20 from derailing or jamming due to track misalignment.

[0033] Reference Appendix Figure 10 -Appendix Figure 13 The fixing assembly includes multiple first inserts 5, which are fixedly connected to the upper and lower ends of multiple uprights 2 respectively. Multiple corner blocks 1 are provided with second slots 33 in the middle. Multiple first inserts 5 are slidably connected to the middle of multiple second slots 33 respectively. Multiple crossbars 4 are fixedly connected with fixing blocks 37 in the middle. A round rod 38 is fixedly connected to the middle of the fixing block 37. A second insert 39 is slidably connected to the outer periphery of the round rod 38. A stop block 40 is fixedly connected to the outer periphery of the second insert 39. Multiple corner blocks 1 are provided with first slots 32 in the middle. The second insert 39 is slidably connected to the middle of the first slot 32. Multiple vertical rods 3 are provided with threaded holes 43 in the middle. Multiple corner blocks 1 are slidably connected with fixing bolts 11 in the middle. Multiple fixing bolts 11 pass through multiple second inserts 39 and multiple first inserts 5 respectively and are threadedly connected to the middle of the threaded holes 43.

[0034] In one specific embodiment, the fixing assembly uses a combination of pre-insertion and bolt locking as the connecting frame. When the crossbar 4 is aligned with the first slot 32 on the corner block 1, the second insert 39 is pushed to slide on the round rod 38. The stop block 40 is used to limit the sliding displacement of the second insert 39, thereby ensuring that the second insert 39 can be accurately aligned and inserted into the first slot 32 during assembly. During disassembly, the second insert 39 is pulled to slide on the round rod 38, so that the second insert 39 can be retracted into the crossbar 4, preventing the crossbar 4 from being blocked during disassembly. When the first insert 5 is inserted into the second slot 33 of the corner block 1, and the second insert 39 is inserted into the first slot 32 of the corner block 1, the insertion and engagement in all directions bear most of the shear force and bending moment of the upright 2 and the crossbar 4. The fixing bolt 11 passes through the first insert 5 and the second insert 39 and is screwed into the threaded hole 43 of the longitudinal rod 3, pressing the upright 2, the crossbar 4, the longitudinal rod 3, and the corner block 1 axially. The number of fixing points in traditional welding or multi-bolt connections is reduced, and the load is transferred by utilizing the large-area contact of the first insert 5, the second slot 33, the second insert 39 and the first slot 32, which effectively disperses the stress concentration at the node.

[0035] Reference Appendix Figure 10 -Appendix Figure 12 Each of the corner blocks 1 has a first limiting groove 34 on its outer wall, and each of the two ends of the multiple crossbars 4 is fixedly connected to a first limiting block 41. The first limiting block 41 is slidably connected to the middle of the first limiting groove 34. Each of the corner blocks 1 has a second limiting groove 35 on its outer wall, and each of the two ends of the multiple vertical bars 3 is fixedly connected to a second limiting block 42. The second limiting block 42 is slidably connected to the middle of the second limiting groove 35.

[0036] In one specific embodiment, the cooperation of the first limiting block 41 with the first limiting groove 34 and the second limiting block 42 with the second limiting groove 35 forms an auxiliary positioning and anti-torsional structure. During assembly, the first limiting block 41 with the first limiting groove 34 and the second limiting block 42 with the second limiting groove 35 act as guides, ensuring that the crossbar 4 and the longitudinal bar 3 are quickly aligned. During stress, the contact between the first limiting block 41 with the first limiting groove 34 and the second limiting block 42 with the second limiting groove 35 restricts the torsional freedom of the crossbar 4 and the longitudinal bar 3 relative to the corner block 1, further increasing the node rigidity and sharing part of the torque load transmitted to the fixed component.

[0037] Reference Appendix Figure 10 and attached Figure 13 The outer walls of multiple corner blocks 1 are provided with positioning grooves 36, and the two ends of multiple uprights 2 are fixedly connected with positioning blocks 44, which are slidably connected in the middle of the positioning grooves 36.

[0038] In one specific embodiment, the positioning block 44 is embedded in the positioning groove 36 to achieve a shape fit between the upright 2 and the corner block 1. This not only assists in the verticality correction of the upright, but also, when subjected to lateral wind loads or stacking eccentric loads, utilizes the supporting effect of the groove wall on the positioning block to share the shear stress at the end of the upright, protecting the internal fixing components from failure due to excessive stress.

[0039] Reference Appendix Figure 4 and attached Figure 5 A pull rod 12 is fixedly connected to the outer side of the second support plate 23. The pull rod 12 passes through the first skin 8 and is used to pull the second support plate 23.

[0040] In one specific embodiment, the pull rod 12 is exposed on the outside of the skin as an operating handle. By applying a pulling force to the pull rod 12, the operator can directly drive the internal second support plate 23 to slide along the guide rail. This effectively transmits the external operating force to the internal support structure, making the folding and storage operation of the wall panel simple and effortless.

[0041] Reference Appendix Figure 1 and attached Figure 2 The top of the frame assembly is provided with a top plate 6, and the outside of the frame assembly is provided with a back plate 9. The top plate 6, the back plate 9, the second support plate 23, multiple third support plates 24, multiple fourth support plates 25, the first support plate 22 and the frame assembly are all made of basalt composite material.

[0042] In one specific embodiment, basalt composite material exhibits excellent specific strength and physicochemical stability. Compared to traditional carbon steel, basalt composite material has a much lower density than steel, but its tensile strength is higher. The application of this material reduces the overall mass of the back panel 9, top panel 6, back panel 9, second support plate 23, multiple third support plates 24, multiple fourth support plates 25, first support plate 22, and frame components, thereby significantly reducing the container's weight and effectively improving the economic efficiency and energy utilization of a single transport. Simultaneously, basalt composite material naturally possesses excellent corrosion resistance, acid and alkali resistance, and aging resistance. In harsh environments with high humidity and high salt spray, it can effectively resist chemical corrosion, avoiding the rusting problem of traditional metal containers, extending the service life of the container, reducing maintenance costs, and effectively reducing the cost of frequent surface anti-corrosion (coating) of traditional metal containers. Furthermore, the production process of basalt composite material is energy-efficient and pollution-free, and it is easy to handle and recycle after disposal, ensuring the structural stability and environmental protection properties of the container during long-term, high-frequency circulation.
