Description

Technical Field

[0001] This utility model relates to an external corner post assembly for a container, belonging to the field of container technology. Background Technology

[0002] As a core component of the global logistics system, container shipping operates efficiently based on the container corner fitting standards established by the International Organization for Standardization (ISO). This standard system ensures seamless connections between different modes of transport, achieving continuous door-to-door transportation. However, in actual logistics operations, there are a large number of non-standard sized or specially structured special containers (such as equipment compartments, generator sets, mobile laboratories, etc.), which are usually loaded inside standard containers for initial transport.

[0003] When these specialized containers arrive at the transit station or destination and need to be detached from their external containers to enter the next stage of transportation, they face a serious technical bottleneck: the container itself lacks corner fittings that meet ISO standards, making it impossible to use common port lifting equipment, transport vehicles, and yard facilities for operations.

[0004] This structural defect forces the logistics chain of specialized containers to be interrupted after they are removed from the standard outer shell. Currently, the industry mainly uses two methods to solve this problem: one is to permanently modify the container structure by welding fixed corner brackets. This method compromises the structural integrity of the container, and the modified corner bracket positions often cannot meet the needs of various operational scenarios. The other is to use temporary binding spreaders, which have significant drawbacks such as high safety hazards, low operational efficiency, and insufficient reliability. Although there are some external corner bracket solutions in existing technologies, most suffer from complex structures, cumbersome installation, unreliable locking, and inability to achieve synchronous operation, making them difficult to promote and apply in actual logistics environments.

[0005] Specifically, existing external corner post devices have the following main technical defects: First, the upper and lower locking mechanisms usually need to be operated separately, making it impossible to achieve synchronous locking and releasing, resulting in cumbersome operation procedures and low work efficiency; second, the lack of effective guiding and limiting structures makes them prone to wear and corrosion during long-term use, leading to a decrease in locking position accuracy and posing safety hazards; third, the transmission mechanism is poorly designed, easily causing motion interference and affecting service life; finally, the overall structure is complex, manufacturing costs are high, and installation and maintenance are inconvenient, restricting its large-scale application in actual logistics.

[0006] Therefore, there is an urgent need for a dedicated external corner post assembly that is structurally sound, easy to operate, reliably locked, and easy to install and maintain, which can quickly and safely convert non-standard containers into transport units with standard lifting points, thereby truly achieving standardization and seamless connection of the entire logistics chain.

[0031] The present invention will be further described below with reference to specific embodiments, and the advantages and features of the present invention will become clearer as a result of the description. However, these embodiments are merely exemplary and do not constitute any limitation on the scope of the present invention. Those skilled in the art should understand that modifications or substitutions can be made to the details and form of the technical solution of the present invention without departing from the spirit and scope of the present invention, but all such modifications and substitutions fall within the protection scope of the present invention.

[0032] See Figures 1 to 9 This utility model relates to an external corner post assembly for a container, comprising: a corner post 2, wherein a corner plate 1 is fixedly installed at the upper and lower ends of the corner post 2 respectively; The locking support assembly consists of two sets: an upper locking support assembly and a lower locking support assembly, both of which are hinged to the corner post 2. One locking support assembly is close to the upper corner plate 1, and the other locking support assembly is close to the lower corner plate 1. A rotary drive assembly is rotatably mounted in the middle of the corner post 2. The rotary drive assembly is hinged to the upper locking support assembly via the upper connecting rod 14 and to the lower locking support assembly via the lower connecting rod 19. When the rotary drive assembly rotates, it synchronously drives the upper locking support assembly and the lower locking support assembly to rotate.

[0033] The central rotary drive assembly, in conjunction with the upper and lower linkage mechanisms, enables synchronous operation of the upper and lower locking support assemblies. Only one drive component needs to be operated to lock or release both ends, significantly improving loading and unloading efficiency.

[0034] The locking support assembly and the corner post are connected by a hinge and a limiting hole, and a pressure block and a retaining ring are set as a guide and limiting structure, which effectively improves the centering accuracy and stability during the locking process and prevents locking failure caused by vibration or off-center load.

[0035] It can be attached to the outside of non-standard containers to give them the function of standard corner bracket lifting points, and is compatible with existing lifting and stacking equipment, effectively expanding the versatility and multimodal transport capabilities of special containers.

[0036] The rotary drive assembly includes a turntable 13, a stop 11, a support frame 12, a shaft 10, and a handle 9. The shaft 10 is rotatably mounted on the corner post 2 via the support frame 12. The handle 9 is installed at the outer end of the shaft 10, and the turntable 13 is installed at the inner end. The stop 11 is also installed on the shaft 10, located on one side of the support frame 12, and the turntable 13 is located on the other side of the support frame 12. The external handle facilitates manual force application, enabling precise rotation of the turntable. The overall structure is simple, with clear connections between components, facilitating disassembly, replacement, and routine maintenance. The stop 11 on the shaft 10, in conjunction with the support frame 12, restricts axial movement of the shaft during rotation, preventing transmission failure due to component displacement and improving operational stability and safety.

[0037] The lower end of the upper connecting rod is hinged to the turntable 13 via a pin 15; the upper end of the lower connecting rod is hinged to the turntable 13 via a pin 15; the upper connecting rod and the lower connecting rod are located on both sides of the turntable 13.

[0038] The upper and lower locking support assemblies have the same structure, both including a galvanized bolt 4, a first retaining ring 5, a support block 6, and a lock head 7. The support block 6 is rotatably installed in the limiting hole of the corner post 2. The lock head 7 is located on one side of the support block 6, with one end extending into the center hole of the support block 6 and rotatably engaging with it. The other end of the lock head is located outside the corner post 2, forming a hook-shaped locking end. The first retaining ring 5 is located on the other side of the support block 6. The threaded portion of the galvanized bolt 4 passes through the first retaining ring 5 and is welded to it. The threaded portion of the galvanized bolt 4 is threadedly engaged with the lock head 7.

[0039] One end of the lock head rotates with the support block, while the other end forms an exposed hook-shaped locking end, which facilitates lifting and ensures stable load-bearing capacity.

[0040] The system uses galvanized bolts and a dual connection method of welding and threaded engagement, which not only ensures a strong connection but also provides excellent rust resistance, making it suitable for humid and harsh environments such as ports and seaports, thus extending the overall service life. The lock head and galvanized bolts are threaded together, and the extension length of the lock head can be adjusted by turning it to compensate for gaps caused by wear, maintain effective locking force for a long time, and the components are highly standardized, making on-site replacement simple.

[0041] A second retaining ring 17 is welded to the periphery of the support block 6.

[0042] Inside the corner post 2, a second retaining ring 17 is welded to the support block 6 along the circumferential direction of the limiting hole. A first pressing block 18 is welded to the inner side of the corner post 2. The first pressing block 18 is located on the periphery of the assembly formed by the lock head 7, the second retaining ring 17 and the support block 6. When the assembly rotates, the assembly rotates with the first pressing block 18 and is guided by the first pressing block 18.

[0043] The first pressure block is arranged around the outer circumference of the lock head, providing stable radial guidance and circumferential limiting for the lock head rotation process.

[0044] The first pressure block is welded to the outside of the support block. It not only serves as a guide but also strengthens the local structural rigidity around the corner post limiting hole, effectively resisting the lateral forces generated during locking and bearing, and ensuring the stability of the overall structure.

[0045] Inside the corner post 2, several second pressure blocks 8 are welded along the circumferential direction of the limiting hole. The second pressure blocks 8 are located around the support block 6 and the first retaining ring 5. When the support block 6 and the first retaining ring 5 rotate, the support block 6 and the first retaining ring 5 rotate in conjunction with the second pressure blocks 8. The second pressure blocks 8 guide the support block 6 and the first retaining ring 5.

[0046] The second pressure block 8 is arranged circumferentially along the inner limiting hole of the corner post, providing precise inner circumferential guidance and limiting for the rotational movement of the support block and the first retaining ring, ensuring that its rotation trajectory is stable and controllable, and effectively preventing deviation or jamming during operation.

[0047] When the support block and the first retaining ring rotate and bear load, their outer periphery cooperates with the second pressure block, so that the force can be evenly distributed to the inner wall of the corner column, which significantly improves the load-bearing capacity of the local structure and the overall rigidity.

[0048] It also includes a connecting plate 16, the upper end of the upper connecting rod 14 is hinged to one end of the connecting plate 16 of the upper locking support assembly, and the other end of the connecting plate 16 of the upper locking support assembly is welded to the support block 6 of the upper locking support assembly; the lower end of the lower connecting rod 19 is hinged to one end of the connecting plate 16 of the lower locking support assembly, and the other end of the connecting plate 16 of the lower locking support assembly is welded to the support block 6 of the lower locking support assembly.

[0049] The rotational motion of the rotary drive assembly is converted into the rotation of the support block, forming a stable force transmission path and ensuring reliable execution of the locking action. The rigid connection between the upper and lower connecting plates and the corresponding connecting rods and support blocks ensures that the upper and lower locking support assemblies rotate synchronously via the rotary drive assembly, effectively avoiding jamming or incomplete locking problems that may be caused by asynchronous actions.

[0050] A reinforcing plate 3 is installed at the weld between the corner plate 1 and the corner post 2. The reinforcing plate between the corner post and the corner plate enhances the overall strength of the connection area; the locking force is effectively transmitted to the corner post body through the support block and the lock head, the force transmission path of the structure is clear, and the overall rigidity and load-bearing capacity are significantly improved.

[0051] This utility model also relates to a container, including the aforementioned container external corner post assembly.

[0052] This utility model relates to an external corner post assembly for a container, which is based on a rotary drive component that synchronously drives the upper and lower locking support components through a linkage mechanism to achieve fast and reliable locking and releasing. Its working principle is as follows: Step 1: Standby Status When not in a lifting position, this corner post assembly serves as a permanent structure at the corner of the container. The hook-shaped ends of the upper and lower locking support assemblies are typically at a preset angle, ready for subsequent lifting or locking operations.

[0053] Step 2: Synchronization Drive When lifting or securing containers is required, the operator turns the handle 9 of the rotary drive assembly located in the middle of the corner post 2. The handle 9 drives the shaft 10 to rotate, and the turntable 13 fixed inside the shaft 10 rotates synchronously. The stop block 11 on the shaft 10 cooperates with the support frame 12 to effectively prevent axial movement of the shaft during rotation, ensuring the stability of the drive.

[0054] Step 3: Force Transmission and Conversion The rotation of turntable 13 is transmitted synchronously to its upper and lower ends via upper connecting rod 14 and lower connecting rod 19, which are respectively hinged to its two sides. The other end of the connecting rod is connected to the support block 6 of the upper and lower locking support assembly via connecting plate 16. Therefore, the rotation of turntable 13 is converted into synchronous rotation of support block 6 within the limiting hole of corner post 2.

[0055] Step 4: Lock Cylinder Positioning and Load Bearing The rotation of support block 6 causes the locking head 7, which it meshes with, to rotate as well. Locking head 7 is an inherent load-bearing component of the container, with one end designed as a hook for easy lifting. During operation: The lock head 7 rotates to the working position, and its hook-shaped end is precisely positioned at the working angle to ensure smooth and reliable engagement with the lock hole of an external lifting device or a twist lock on a transport vehicle. In this position, the lock head 7 will bear the entire load during lifting and transportation.

[0056] Guiding and Stability: During this process, the first pressure block 8 welded to the outside of the corner post provides peripheral guidance and limitation for the rotation of the lock head 7, ensuring its rotation trajectory is accurate and without wobbling; the second pressure block 18 welded inside the corner post provides internal peripheral guidance for the support block 6 and the first retaining ring 5, ensuring the smooth rotation of the entire assembly. The second retaining ring 17 around the support block 6 further enhances its structural stability.

[0057] Step 5: Torque Transmission and Overall Load Bearing During lifting or transportation, the external load is transferred to the support block 6 through the lock head 7, then distributed to the corner post 2 through the support block 6, and finally converges on the corner plate 1, which conforms to ISO standard specifications, thus completing the force transfer. The reinforcing plate 3 at the weld between the corner plate 1 and the corner post 2 enhances the strength of this connection area, ensuring the overall structural strength and durability of the container under frequent lifting and harsh working conditions.

[0058] Step Six: Reset Process When the hoisting or locking operation is completed and it is necessary to disengage the lock head 7 from its working state, turn the handle 9 in the opposite direction. Through the aforementioned transmission action, the lock head 7 is driven to rotate synchronously in the opposite direction, causing its hook-shaped end to move away from the working position and return to its initial state.

[0059] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
