Description

Technical Field

[0001] This application relates to the field of logistics equipment and warehousing technology, and in particular to a foldable logistics turnover box. Background Technology

[0002] Logistics turnover boxes are standardized containers used for loading, handling, and storing goods in logistics transportation, warehousing, and distribution. They are usually made of materials such as plastic and metal, and have the characteristics of high strength, wear resistance, and corrosion resistance, effectively protecting goods from damage during circulation. Their standardized design makes them easy to use with warehousing and logistics equipment such as forklifts and racks, enabling mechanized operations and improving work efficiency. At the same time, some turnover boxes are also foldable and nestable, saving space when not in use and reducing warehousing and transportation costs. They are an important tool in the modern logistics system for achieving efficient flow of goods and ensuring the smooth operation of the supply chain.

[0003] Foldable logistics turnover boxes achieve their function through a special structural design. The various parts of the box are connected by hinges, buckles, or slide rails. After use, the locking device is released, and the parts can rotate, slide, or nest flexibly along the connecting parts. The box volume is reduced by folding and shrinking, saving storage and transportation space. When it is needed again, the box is unfolded and locked again to restore its load-bearing function and meet the needs of various logistics links.

[0004] However, some existing foldable logistics turnover boxes suffer from cumbersome top-to-body connection issues. The connection process is complex, requiring operators to spend considerable time and effort on alignment and fastening, thus reducing logistics efficiency. Furthermore, some turnover boxes lack adaptability in their top-to-body connection structure, making it difficult to achieve stable and suitable fixing for goods of different sizes and weights. This fails to meet diverse logistics transportation needs and limits the effectiveness of foldable logistics turnover boxes in practical applications. Therefore, a foldable logistics turnover box is proposed to address these problems. Utility Model Content

[0008] Preferably, the limiting mechanism includes multiple rotating shafts, with the outer sides of the multiple rotating shafts fixedly connected to the inner walls of the two long baffles. Each of the multiple rotating shafts is rotatably connected to a limiting plate. A fixing rod is rotatably connected to the inner wall of the multiple limiting plates on adjacent sides. A connecting block is fixedly connected to the top of the multiple limiting plates on adjacent sides. A damping column is rotatably connected to the top of the multiple connecting blocks. A spring is sleeved on the outer side of each of the multiple damping columns. A connecting rod is fixedly connected to the top of each of the multiple fixing rods on both sides. A control rod is fixedly connected to the outer side of the multiple connecting rods on opposite sides. By adopting the above technical solution, the limiting mechanism uses the rotating shaft fixed to the inner wall of the long baffle as the fulcrum. When the limiting plate rotates around the shaft, it is linked with the fixed rod, the connecting rod and the control rod. The operation of the control rod can drive the limiting plate to move. At the same time, the connecting block, the damping column and the spring cooperate to achieve reset through damping buffer and spring energy storage when the limiting plate rotates, thereby limiting and fixing the turnover box component.

[0009] Preferably, the external fixed disks of the plurality of fixed disks are fixedly connected to the inner wall of the bottom end of the top cover, the external sliding connection of the plurality of springs II is to the inner wall of the bottom end of the top cover, and the external fixed connection of the plurality of L-shaped fixed plates is to the inner wall of the plurality of concave plates II. By adopting the above technical solution, the fixed plate is fixed to the inner wall of the top cover, providing a sliding track for the push column and transmitting its force. The two springs are sleeved on the outside of the push column and slide in cooperation with the inner wall of the top cover, which can provide a reset elastic force and enhance the sealing effect of the top cover. The L-shaped fixed plate is fixed to the inner wall of the concave plate, realizing a stable connection between the long baffle and the short baffle, and ensuring the structural strength of the turnover box.

[0010] Preferably, the two fixed blocks are fixedly connected to the inner wall of the long baffle on opposite sides, the outer sides of the multiple support bars are slidably connected to the inner wall of the top of the two long baffles, the outer sides of the multiple limiting blocks are slidably connected to the inner wall of the two long baffles, and the outer sides of the multiple triangular plates are slidably connected to the inner wall of the two long baffles. By adopting the above technical solution, the fixing block three is fixed to the inner wall of the long baffle, providing support for the damping rod two to constrain the movement of the rotating plate; the support bar, the limiting block, and the triangular plate are respectively slidably engaged with the long baffle, the support bar helps the top cover to accurately connect with the long baffle, and the limiting block and the triangular plate cooperate to achieve reliable locking, jointly ensuring the structural stability of the turnover box.

[0011] Preferably, the outer surfaces of the plurality of support bars are slidably connected to the inner wall of the bottom end of the top cover, and the top end of the triangular plate is fixedly connected to the top ends of the two limiting blocks; By adopting the above technical solution, the support bar slides in conjunction with the inner wall of the top cover, allowing it to slide inside the top cover and evenly transmit the pressure of the top cover to the long baffle; the top of the triangular plate is fixedly connected to the limiting block to form a linkage locking structure, ensuring that the two move synchronously and jointly enhancing the stability of the turnover box structure.

[0012] Preferably, the top ends of the plurality of damping columns are fixedly connected to the inner walls of the two long baffles, and the outer sides of the plurality of control rods are slidably connected to the inner walls of the two long baffles. By adopting the above technical solution, the top of the damping column is fixed to the inner wall of the long baffle, providing elastic support for the limiting plate to stably press the L-shaped fixing plate; the control rod slides with the long baffle, and the operator can drive the limiting mechanism to move through the sliding control rod to realize the limiting and release of the turnover box components.

[0013] Preferably, the bottom ends of the plurality of limiting plates are fixedly connected to the top ends of the plurality of concave plates one, the bottom ends of the plurality of limiting plates are fixedly connected to the top ends of the plurality of concave plates two, and the bottom ends of the plurality of limiting plates are fixedly connected to the top ends of the plurality of L-shaped fixing plates. By adopting the above technical solution, the bottom end of the limiting plate is fixedly connected to the concave plate one, the concave plate two, and the L-shaped fixing plate respectively. Through secondary reinforcement and symmetrical constraint of the connection points of the three, a triple locking structure is formed, eliminating the connection gap, ensuring that the forces on both sides of the short baffle are balanced, and ensuring the overall stability of the turnover box.

[0014] In summary, this application includes at least one of the following beneficial technical effects: 1. In this utility model, a triangular plate is fixed by a limiting block. The triangular plate drives the support bar to move, and the support bar in turn drives the top cover to be fixed with the long baffle and the short baffle to form a closed space. When unfolded or folded, each component moves in coordination through damping rods, springs and other structures to release or restore the fixed state, thereby achieving the effect of quick opening and closing and stable fixing of the turnover box. This not only ensures the airtightness of the box and the safety of the goods during transportation, but also facilitates folding and storage, and improves logistics turnover efficiency.

[0015] 2. In this utility model, the damping column pushes the limiting plate to rotate around the pivot to a vertical state. After the limiting plate rotates, it restricts the position of the L-shaped fixing plate within the concave plate one and concave plate two, thereby achieving the positioning and locking of the L-shaped fixing plate, preventing it from detaching from the concave plate one and concave plate two, and ensuring the support stability of the turnover box after it is unfolded.

[0017] The following is in conjunction with the appendix Figure 1 - Appendix Figure 4 This application will be described in further detail below.

[0018] Example: A foldable logistics turnover box, referring to... Figures 1 to 3 The container includes a top cover 1, with two long baffles 2 fixedly connected to the bottom end of the top cover 1. The long baffles 2 enhance the overall strength and stability of the container, enabling it to withstand greater loads. A fixing mechanism 3 is fixedly connected to the inner walls of the two long baffles 2. The function of the fixing mechanism 3 is to ensure a tight connection between the top cover 1, the long baffles 2, and other components when the container is unfolded, preventing loosening or separation and ensuring the container's sealing and stability during loading and transportation. A short baffle 4 is fixedly connected to the bottom end of the top cover 1. Specifically, the bottom of the top cover 1 is fixedly connected to the long baffle 2 and the short baffle 4 to form the turnover box frame. The long baffle 2 enhances the load-bearing capacity of the box, while the fixing mechanism 3 ensures that the top cover 1 is tightly connected to each component in the unfolded state, ensuring the sealing and stability of the turnover box during use.

[0019] The short baffle 4 and the long baffle 2 together form the four walls of the turnover box, which enclose the side space of the box and further enhance the sealing and structural stability of the turnover box. A base plate 5 is fixedly connected to the bottom end of the two long baffles 2. The base plate 5, through its fixed connection with the long baffles 2, evenly distributes the load to the entire box structure. A limiting mechanism 6 is fixedly connected to the inner wall of the two long baffles 2. The main function of the limiting mechanism 6 is to limit the position of relevant components after the turnover box is unfolded, preventing displacement or detachment during use and ensuring the stability of the turnover box structure. Two concave plates 7 are fixedly connected to the opposite sides of the two long baffles 2. Specifically, the short baffle 4 and the long baffle 2 form four walls to enhance sealing and stability, the bottom plate 5 transmits the load, the limiting mechanism 6 limits the position of the components to prevent displacement, and the concave plate 7 provides auxiliary connection, all of which together ensure the structural stability of the turnover box.

[0020] The concave plate 7 is mainly used to cooperate with other components to connect and fix the various parts of the turnover box, playing an important role in the structural assembly and stable support of the turnover box. The fixing mechanism 3 includes multiple connecting shafts 31, the two sides of which are fixedly connected to the inner walls of two long baffles 2. The connecting shafts 31 are key components in the fixing mechanism 3 to realize the rotation of the components, providing rotation fulcrums for components such as the rotating plate 32. The rotating plates 32 are rotatably connected to the outside of the multiple connecting shafts 31. The rotating plates 32 rotate under the support of the connecting shafts 31. Limiting blocks 33 are fixedly connected to the adjacent sides of the two rotating plates 32. The limiting blocks 33 cooperate with the rotating plates 32 to limit the position of other components, thereby achieving further fixation and stability of the turnover box structure. Specifically, the concave plate 7 assists in connecting and fixing the various components of the turnover box. In the fixing mechanism 3, the connecting shaft 31 provides a rotation fulcrum for the rotating plate 32. When the rotating plate 32 rotates, it drives the limiting block 33, thereby limiting the position of other components to strengthen the turnover box structure.

[0021] Multiple connecting shafts 34 are fixedly connected to the inner wall of the bottom end of the top cover 1. Similar to connecting shaft 31, connecting shafts 34 provide rotation fulcrums for components such as support bars 35. Support bars 35 are rotatably connected to the outside of each connecting shaft 34. The support bars 35 rotate under the support of the connecting shafts 34, serving to support and fix the top cover 1. Triangular plates 36 are fixedly connected to the bottom ends of each support bar 35. The triangular plates 36 cooperate with the support bars 35, and through interaction with components such as limiting blocks 33, limit and fix the support bars 35. Connecting components 37 are fixedly connected to the bottom ends of multiple rotating plates 32. Through the coordinated work of their internal components, a stable connection and linkage between the rotating plates 32 and other components of the turnover box are achieved, ensuring the structural stability of the turnover box in its unfolded state. Specifically, the connecting shaft 34 on the inner wall of the bottom end of the top cover 1 provides a fulcrum for the support bar 35. When the support bar 35 rotates, it drives the triangular plate 36 to cooperate with the limiting block 33 to achieve its own limiting and fixing. At the same time, the connecting component 37 at the bottom end of the rotating plate 32, through the cooperation of internal components, ensures that the rotating plate 32 is stably connected and linked with other components, and together maintains the structural stability of the unfolded state of the turnover box.

[0022] Reference Figures 2 to 4 The limiting mechanism 6 includes multiple rotating shafts 61, which are the core rotational fulcrums of the limiting mechanism 6, providing basic support for the movement of the entire mechanism. The two sides of the multiple rotating shafts 61 are fixedly connected to the inner walls of two long baffles 2. Fixing the rotating shafts 61 to the inner walls of the long baffles 2 forms a rigid connection between the limiting mechanism 6 and the main structure of the turnover box. Limiting plates 62 are rotatably connected to the outside of each of the multiple rotating shafts 61. The limiting plates 62 limit and release the L-shaped fixed plate 9 by rotating around the rotating shafts 61. Fixed rods 63 are rotatably connected to the inner walls of adjacent sides of the multiple limiting plates 62. Specifically, in the limiting mechanism 6, the rotating shaft 61 is fixed to the inner wall of the long baffle 2 as the core rotation fulcrum, providing support for the movement of the mechanism. The limiting plate 62 rotates around the rotating shaft 61 to realize the limiting and release of the L-shaped fixed plate 9. The fixed rod 63 is rotatably connected to the limiting plate 62 to assist in realizing the overall limiting function.

[0023] The fixed rod 63 connects the two limiting plates 62 to achieve synchronous motion control. Connecting blocks 64 are fixedly connected to the top of adjacent sides of multiple limiting plates 62. Connecting blocks 64 serve as the connection medium between the limiting plates 62 and the damping columns 65, transmitting elastic force. Damping columns 65 are rotatably connected to the outer top of each of the multiple connecting blocks 64. When the limiting plates 62 rotate, the connecting blocks 64 cause the damping columns 65 to extend and retract. The damping columns 65 slow down their movement through their internal damping structure, while the spring 66 generates elastic potential energy due to deformation. When the external force is removed, the elastic force of the spring 66 pushes the damping columns 65 back to their original position, causing the limiting plates 62 to return to their initial position. Springs 66 are fitted onto the outer surface of each of the multiple damping columns 65. Specifically, the fixed rod 63 connects the two limit plates 62 to achieve synchronous movement, and the connecting block 64 serves as a medium to connect the limit plate 62 and the damping column 65. When the limit plate 62 rotates, it drives the damping column 65 to extend and retract, and the damping column 65 slows down the movement speed. The spring 66 stores elastic potential energy. After the external force is removed, the spring 66 pushes the damping column 65 to reset, so that the limit plate 62 returns to the initial position.

[0024] When the limiting plate 62 rotates, compressing the damping column 65, the spring 66 is simultaneously compressed and stores elastic potential energy. When the control rod 68 releases external force, the elastic potential energy of the spring 66 is converted into kinetic energy, pushing the damping column 65 and the connecting block 64 to move, causing the limiting plate 62 to reset and press against the L-shaped fixed plate 9. Connecting rods 67 are fixedly connected to the top ends of both sides of the multiple fixed rods 63. When the control rod 68 is pulled or pushed, the force is transmitted to the fixed rods 63 through the connecting rods 67. Since the connecting rods 67 are perpendicularly fixed to the fixed rods 63, the horizontal operating force can be converted into the rotational torque of the fixed rods 63, thereby driving the limiting plate 62 to move. Control rods 68 are fixedly connected to the opposite sides of the multiple connecting rods 67. The control rod 68 is the operating input end of the limiting mechanism 6, allowing the operator to control the state of the limiting plate 62. Specifically, the control lever 68, as the operating end, is pulled or pushed, and the horizontal force is converted into the rotational torque of the fixed lever 63 through the connecting lever 67, which drives the limit plate 62 to move. When the limit plate 62 rotates and the damping column 65 is compressed, the spring 66 stores elastic potential energy. After the control lever 68 releases the external force, the spring 66 pushes the damping column 65 to reset, which drives the limit plate 62 to press the L-shaped fixed plate 9.

[0025] Reference Figures 1 to 3 The connecting component 37 includes multiple fixing blocks 371, the top ends of which are fixedly connected to the bottom ends of multiple rotating plates 32. Two concave plates 8 are fixedly connected to the opposite sides of the two short baffles 4. The concave plates 8 serve as the connection medium between the short baffles 4 and the L-shaped fixing plates 9. Through their fixed connection with the short baffles 4, the concave plates 8 form a lateral support frame. One end of the L-shaped fixing plate 9 is embedded in its groove, achieving an indirect connection between the short baffles 4 and the long baffles 2. L-shaped fixing plates 9 are fixedly connected to the inner walls of the multiple concave plates 7. The L-shaped fixing plates 9 act as a bridge connecting the concave plates 7 and the concave plates 8, achieving bidirectional fixation through the L-shaped structure. Specifically, in the connecting component 37, the fixing block 371 connects the rotating plate 32 and the connecting component 37. The concave plate 8 serves as the connecting medium between the short baffle 4 and the L-shaped fixing plate 9, forming a lateral support frame to achieve the indirect connection between the short baffle 4 and the long baffle 2. The L-shaped fixing plate 9 fixes the concave plate 7 and the concave plate 8 in both directions by means of the L-shaped structure, thus jointly ensuring the stability of the turnover box structure.

[0026] Two fixed blocks 371 are rotatably connected to adjacent sides of a damping rod 372. When the rotating plates 32 on both sides swing inward or outward, the damping rod 372 extends and retracts with the movement of the fixed blocks 371. The internal damping structure slows down the movement speed and prevents the rotating plates 32 from rapidly colliding with other components. A spring 373 is fitted around the outside of each damping rod 372. The spring 373 provides a restoring force for the rotating plates 32. Two fixed blocks 374 are fixedly connected to the far ends of the tops of the two rotating plates 32. Fixed blocks 374 are the connection points between the rotating plates 32 and the damping rods 375, used to convert the swinging motion of the rotating plates 32 into the extension and retraction motion of the damping rods. Specifically, the damping rod 372, which is rotatably connected between the two fixed blocks 371, swings and extends with the rotating plate 32 and slows down its movement speed. The externally sleeved spring 373 provides a restoring force. The fixed block 374, as a connecting node, converts the swing of the rotating plate 32 into the extension and retraction of the damping rod 375, and works together to ensure the stable operation of the connecting assembly 37.

[0027] Damping rods 375 are rotatably connected to the opposite sides of two fixed blocks 374. Damping rods 375 are elastic supports connecting the rotating plate 32 and the long baffle 2, limiting the maximum swing angle of the rotating plate 32 through their cooperation with fixed block 376. Fixed blocks 376 are rotatably connected to the opposite sides of two damping rods 375. Fixed blocks 376 are fixed to the inner wall of the long baffle 2, serving as the fixed fulcrum for damping rods 375 and transmitting the force of the damping rods to the long baffle 2. Fixed blocks 377 are fixedly connected to the opposite sides of multiple support bars 35. Fixed blocks 377 are the connecting hubs between the support bars 35 and the push column 379, used to convert the rotation of the support bars 35 into the linear motion of the push column 379. Push columns 379 are rotatably connected to the opposite sides of multiple fixed blocks 377. Push columns 379 push the top cover 1 against the side wall by sliding within the fixed plate 378. Each of the multiple pushers 379 has two fixed plates 378 that are slidably connected to its exterior. Specifically, the damping rod 375 cooperates with the fixing block 376 fixed on the inner wall of the long baffle 2 to limit the swing angle of the rotating plate 32 as an elastic support and transmit the force to the long baffle 2; the fixing block 377 connects the support bar 35 and the push column 379, so that the rotation of the support bar 35 is converted into the linear sliding of the push column 379 in the fixed plate 378, thereby pushing the top cover 1 to fit against the side wall.

[0028] Fixed disc 378 is fixed to the inner wall of top cover 1, providing a sliding track and limiting support for push column 379, ensuring stable axial movement of push column 379. Multiple push columns 379 are each fitted with a second spring 301. The second spring 301, fitted to the outside of the push column 379, provides a restoring elastic force for the push column 379, and simultaneously enhances the sealing effect of top cover 1 through pre-tightening force. Multiple fixed discs 378 are externally fixedly connected to the inner wall of the bottom end of top cover 1. The fixed connection between the fixed discs 378 and top cover 1 directly transmits the force of the push column 379 to top cover 1, forming a stable force system. Multiple second springs 301 are externally slidably connected to the inner wall of the bottom end of top cover 1. The sliding fit between the second spring 301 and the inner wall of top cover 1 allows the spring to deform freely during extension and contraction, while preventing lateral displacement of the spring. Multiple L-shaped fixed plates 9 are externally fixedly connected to the inner walls of multiple concave plates 8. Specifically, the fixed plate 378 is fixed to the inner wall of the top cover 1, providing a sliding track and limiting support for the push column 379, and transmitting the force of the push column 379 to form a stable force system; the second spring 301 is sleeved on the outside of the push column 379, providing a reset elastic force and enhancing the sealing effect of the top cover 1, and its sliding cooperation with the inner wall of the top cover 1 ensures free expansion and contraction; the L-shaped fixed plate 9 is fixed to the inner wall of the concave plate 8, assisting in the construction of a stable structure for the turnover box.

[0029] The two ends of the L-shaped fixing plate 9 are rigidly connected to the concave plate 7 and the concave plate 8, respectively, so that the forces on the long baffle 2 and the short baffle 4 are transferred to each other through the L-shaped structure to form an overall frame. The opposite sides of the two fixing blocks 376 are fixedly connected to the inner wall of the long baffle 2. The fixed connection between the fixing blocks 376 and the long baffle 2 provides stable support for the damping rod 375, ensuring that it can effectively restrain the movement of the rotating plate 32. The external sliding connection of multiple support bars 35 is slidably connected to the inner wall of the top of the two long baffles 2. The sliding cooperation between the support bars 35 and the long baffle 2 allows the support bars 35 to slide along the inner wall of the long baffle 2 when rotating, so as to achieve precise docking between the top cover 1 and the long baffle 2. Specifically, the L-shaped fixing plate 9, through rigid connection with the concave plate 1 7 and the concave plate 2 8, realizes the force transmission between the long baffle 2 and the short baffle 4, and constructs the overall frame; the fixing block 376 fixed to the inner wall of the long baffle 2 provides support for the damping rod 2 375 to constrain the rotating plate 32, while the support bar 35 slides with the long baffle 2 to help the top cover 1 and the long baffle 2 to accurately connect.

[0030] Multiple limiting blocks 33 are externally slidably connected to the inner walls of two long baffles 2. The sliding engagement of the limiting blocks 33 with the long baffles 2 allows the limiting blocks 33 to slide up and down along the inner walls of the long baffles 2, precisely engaging with the outer surface of the triangular plates 36. Multiple triangular plates 36 are externally slidably connected to the inner walls of the two long baffles 2. The sliding engagement of the triangular plates 36 with the long baffles 2 allows the triangular plates 36 to move with the support bars 35 and reliably lock with the limiting blocks 33. Multiple support bars 35 are externally slidably connected to the inner wall of the bottom end of the top cover 1. The sliding engagement of the support bars 35 with the top cover 1 allows the support bars 35 to slide along the inner wall of the top cover 1, evenly transmitting the pressure of the top cover 1 to the long baffles 2. Specifically, the limiting block 33 and the triangular plate 36 are slidably engaged with the long baffle 2, so that the limiting block 33 can be accurately engaged with the triangular plate 36 and reliably locked; the support bar 35 is slidably engaged with the top cover 1 and the long baffle 2, so that it can slide on the inner wall of the top cover 1 and evenly transmit the pressure of the top cover 1 to the long baffle 2, ensuring the stability of the turnover box structure.

[0031] The top of the triangular plate 36 is fixedly connected to the top of the two limiting blocks 33. The fixed connection between the triangular plate 36 and the limiting blocks 33 forms a linkage locking structure, ensuring that their movements are synchronized. The tops of multiple damping columns 65 are fixedly connected to the inner walls of the two long baffles 2. The fixed connection between the damping columns 65 and the long baffles 2 provides elastic support for the limiting plate 62, ensuring that the limiting plate 62 can stably press against the L-shaped fixing plate 9. The outer surfaces of multiple control rods 68 are slidably connected to the inner walls of the two long baffles 2. The sliding cooperation between the control rods 68 and the long baffles 2 allows the operator to drive the limiting mechanism 6 to move by sliding the control rods 68. The bottom ends of the multiple limiting plates 62 are fixedly connected to the tops of multiple concave plates 7. Specifically, the triangular plate 36 and the limiting block 33 are fixedly connected to form a linkage lock to ensure synchronous movement; the damping column 65 is fixed to the inner wall of the long baffle 2 to provide elastic support for the limiting plate 62, so that it can stably press the L-shaped fixing plate 9. At the same time, the operator drives the limiting mechanism 6 by sliding the control rod 68 that cooperates with the long baffle 2, and the bottom end of the limiting plate 62 is fixed to the concave plate 7, which helps to stabilize the turnover box structure.

[0032] The fixed connection between the limiting plate 62 and the concave plate 7 forms a secondary reinforcement of the connection point between the concave plate 7 and the L-shaped fixing plate 9. The bottom ends of multiple limiting plates 62 are fixedly connected to the top ends of multiple concave plates 8. The fixed connection between the limiting plate 62 and the concave plate 8, together with the connection to the concave plate 7, forms a symmetrical constraint, ensuring balanced force on both sides of the short baffle 4. The bottom ends of multiple limiting plates 62 are fixedly connected to the top ends of multiple L-shaped fixing plates 9. The fixed connection between the limiting plate 62 and the L-shaped fixing plate 9 forms a triple locking structure, completely eliminating connection gaps. Specifically, the limiting plate 62 is fixedly connected to the concave plate 7, the concave plate 8, and the L-shaped fixing plate 9 respectively. This not only reinforces the connection point between the concave plate 7 and the L-shaped fixing plate 9, but also balances the force on both sides of the short baffle 4 through symmetrical constraints, thus forming a triple locking structure that effectively eliminates connection gaps and ensures the stability of the turnover box structure.

[0033] The implementation principle of this application embodiment is as follows: When a sealed space needs to be formed, the rotating plate 32, which rotates externally on the connecting shaft 31, drives the limiting block 33 to move, so that the limiting block 33 fixes the triangular plate 36. After the triangular plate 36 is fixed, it drives the support bar 35, which is fixedly connected to it, to slide on the inner wall of the top of the long baffle 2 and the inner wall of the bottom of the top cover 1. The movement of the support bar 35 then drives the top cover 1, making it tightly fixed with the long baffle 2 and the short baffle 4, ultimately forming a sealed space. In this process, the damping rod 372, spring 373, damping rod 375, fixing block and other structures in the connecting assembly 37 cooperate with each other to ensure the stability and controllability of the movement of the rotating plate 32 and the support bar 35.

[0034] When release is required, push column 379 is pushed, and push column 379 pushes support bar 35 to rotate around connecting shaft 2 34 as fulcrum, disengaging from limit block 33 fixing triangular plate 36, so as to achieve the opening and closing effect of top cover 1 with long baffle 2 and short baffle 4, thereby realizing the effect of quickly and stably forming a sealed space in the turnover box, effectively preventing the goods in the box from getting damp, contaminated, or shaken and damaged during transportation, and improving the practicality and reliability of turnover box in all aspects of logistics.

[0035] When the turnover box is unfolded, the rotating shaft 61 is fixed to the inner wall of the long baffle 2, serving as the fulcrum for the rotation of the limiting plate 62. The limiting plate 62 rotates around the rotating shaft 61 to a suitable position, and the concave plate 7, concave plate 8, and L-shaped fixing plate 9, which are fixedly connected to the bottom end, are then in place. At this time, the limiting plate 62 restricts the L-shaped fixing plate 9 by its own position, making it stably embedded in the concave plate 7 and concave plate 8, preventing it from falling off. At the same time, the connecting block 64 drives the damping column 65 to rotate, and the spring 66 sleeved on the outside of the damping column 65 provides buffering and support for the limiting plate 62, further ensuring the stability of the structure after unfolding.

[0036] When the turnover box needs to be stored, the operator moves the control lever 68, which drives the connecting rod 67 fixedly connected to it. The connecting rod 67 then drives the fixing rod 63, causing the limiting plate 62 to rotate around the rotating shaft 61, releasing the restriction on the L-shaped fixing plate 9, so that each component can be folded and stored. This achieves the effect of stable and reliable support when the turnover box is unfolded, and simple and quick operation when stored, improving warehousing and transportation efficiency and reducing logistics costs.
