Description

Technical Field

[0001] The present invention relates to the technical field of freight containers, and in particular to a freight container locking mechanism which is easy to disassemble. Background Art

[0002] Containers, also known as cargo containers, are large standardized cargo containers that can carry packaged or unpackaged goods for transportation and are easy to load and unload with mechanical equipment. The success of this tool lies in the standardization of its products and the entire transportation system established by it, which allows a behemoth with a load capacity of dozens of tons to be standardized, and on this basis gradually realizes a logistics system that matches ships, ports, routes, roads, transfer stations, bridges, tunnels, and multimodal transport around the world.

[0003] Container transportation is a modern transportation method that uses containers as transportation units to transport goods. It is suitable for ocean transportation, railway transportation and international multimodal transportation, etc. It has the advantages of high standardization, good sealing, low damage rate, intensive, large-scale, liner, low cost, good quality, etc., which greatly improves the safety and efficiency of cargo transportation.

[0004] In the existing freight containers, in order to maintain the stability of the container during transportation, most of the containers stacked from bottom to top are connected by locking mechanisms, and the locking mechanisms are mostly installed at the four corners of the container to achieve the purpose of four-point positioning of the container. However, with the changes in transportation needs, the existing containers need to be gradually locked and disassembled at four points of the container, which is time-consuming and cumbersome. With the long-term operation of the container, if the manually controlled locking mechanism is offset or loosened, it is easy to affect the stability of the container and affect the safety of the container during transportation. Therefore, the present application provides a freight container locking mechanism that is easy to disassemble to meet the needs. Summary of the invention

[0005] In view of the above problems, the present application provides a freight container locking mechanism that is easy to disassemble.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a freight container locking mechanism that is easy to disassemble, comprising four upper pressure blocks and four lower pressure blocks arranged at the four corners of the top and bottom of the container. When the containers are stacked from bottom to top, the lower pressure blocks arranged at the bottom of the upper container are connected to the upper pressure blocks arranged at the top of the lower container.

[0007] The upper pressing blocks are each provided with a docking block extending above them, and the bottom ends of the lower pressing blocks are each provided with a docking groove for accommodating the docking block to move into its inner cavity, and the docking blocks are provided with two locking plates that can open and close, and the upper pressing blocks are provided with a driving unit that can control the synchronous movement of the two locking plates, and when the lower pressing block is connected to the upper pressing block below it, the two locking plates are moved out to the outside of the docking block and pressed against the bottom wall of the lower pressing block, forming an interception structure to prevent the lower pressing block from separating from the upper pressing block.

[0008] Furthermore, the two lower pressing blocks located in the same row are connected by a connecting beam, and an angle groove is provided on the connecting beam. A locking plate that can move synchronously with the locking plate is provided in the relative space between the two upper pressing blocks located in the same row. When the locking plate is pressed against the bottom wall of the lower pressing block, the locking plate is locked into the inner side of the angle groove.

[0009] Furthermore, the ends of the locking plates are provided with adjusting shafts, and the adjusting shafts are arranged on the docking blocks. A group of driven gears are provided on the adjusting shafts. The two groups of driven gears on the two adjusting shafts are meshed and connected. When one group of driven gears rotates synchronously with the adjusting shafts, the other group of driven gears rotates in the opposite direction with the adjusting shafts until the two locking plates are synchronously moved out and moved into the inner side of the docking block.

[0010] Furthermore, the driving unit includes a driving shaft penetrating through the docking block, the driving shaft is distributed in parallel with the adjustment shaft, and a driving gear meshing with one of the two sets of driven gears is provided on the driving shaft.

[0011] The two driving shafts distributed from front to back in the same row both penetrate the upper pressing blocks and are connected with the clamping plates located in the relative spaces between the two upper pressing blocks. When the driving shafts rotate, the clamping plates rotate synchronously.

[0012] Furthermore, the end of the drive shaft away from the locking plate extends to the outside of the upper pressure block, and the end of the drive shaft located outside the upper pressure block is provided with a handle that can rotate synchronously with it. As the handle rotates, the driving gear and the driven gear located inside the docking block rotate synchronously.

[0013] Furthermore, the upper pressure block is provided with a reverse gear block on the side opposite to the handle which can rotate in the direction opposite to the rotation direction of the drive shaft, the reverse gear block is provided with a storage sleeve which can rotate synchronously with the reverse gear block, a movable intercepting rod is provided in the storage sleeve, and the handle is provided with a receiving groove for accommodating the storage sleeve and the intercepting rod, and when the drive shaft and the reverse gear block rotate in opposite directions respectively, the storage sleeve and the intercepting rod pass through the receiving groove.

[0014] Furthermore, a first linkage wheel is provided on the driving shaft, a second linkage wheel is provided obliquely below the first linkage wheel, the first linkage wheel and the second linkage wheel are connected by a synchronous belt, and a synchronous shaft passing through the second linkage wheel is provided on the upper pressure block, and a synchronous gear is provided at one end of the synchronous shaft close to the handle, and the synchronous gear is meshed with the reverse gear block.

[0015] Furthermore, the storage sleeve is threadedly connected to the intercepting rod. When the locking plate is pressed against the bottom wall of the lower pressing block and the positioning plate is inserted into the inner side of the angle groove, the storage sleeve and the intercepting rod are both located below the handle.

[0016] In summary, the technical effects and advantages of the present invention are as follows:

[0017] 1. The present invention can quickly switch the connection status of the two rows of lower pressure blocks and the upper pressure blocks through an adjustable driving unit, and then quickly switch the connection status of the four corners of the container, reducing the time required for locking and disassembly operations point by point, and the connection status of the stacked containers is convenient for rapid disassembly of the containers, which has the advantage of portable operation.

[0018] 2. When adjusting the driving unit, the present invention can also synchronously switch the connection state of the positioning plate and the connecting beam. The combination of the positioning plate and the connecting beam can be located in the relative space of the lower pressing block and the upper pressing block in the same row to form a docking structure. This expands the docking range of the container, further improves the structural strength of the lower pressing block and the upper pressing block when connected, and improves the stability of the connection between the two.

[0019] 3. In the present invention, a storage sleeve and an interception rod are provided that can move synchronously with the drive unit, which have an interception effect on the handle. When the lower pressing block and the upper pressing block are locked, the stability of the handle and the drive shaft is maintained, and the stability of the connection between the locking plate and the lower pressing block is maintained, which can avoid the deviation of the handle caused by external force impact. The use of the storage sleeve and the interception rod to limit the handle can be implemented simultaneously during the operation of the drive unit, without the need to install additional limiting components.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Example 1: Reference Figure 1-10 The illustrated embodiment shows a freight container locking mechanism that is easy to disassemble, comprising four upper pressing blocks 2 and four lower pressing blocks 1 arranged at the four corners of the top and bottom of the container. When the containers are stacked from bottom to top, the lower pressing block 1 arranged at the bottom of the upper container is in contact with the upper pressing block 2 arranged at the top of the lower container.

[0034] Furthermore, in order to maintain the stability of the connection between the upper and lower distributed containers, the upper pressure block 2 is provided with a docking block 21 extending above it, and the bottom end of the lower pressure block 1 is provided with a docking groove 11 that can accommodate the docking block 21 to move into its inner cavity, and the docking block 21 is provided with two locking plates 22 that can be opened and closed, and the upper pressure block 2 is provided with a driving unit that can control the synchronous movement of the two locking plates 22.

[0035] When the lower pressing block 1 is connected to the upper pressing block 2 below it, the two locking plates 22 are moved out to the outside of the docking block 21 and pressed against the bottom wall of the lower pressing block 1, forming an interception structure to prevent the lower pressing block 1 from separating from the upper pressing block 2.

[0036] Therefore, when the containers are stacked for use, after the lower pressure block 1 is connected to the upper pressure block 2, the staff can operate the driving unit to lock the lower pressure block 1 and the upper pressure block 2, which has a four-corner positioning effect on the container, avoiding the container deviation caused by the separation of the lower pressure block 1 and the upper pressure block 2, and effectively ensuring the stability and safety of the container during the freight process.

[0037] like Figure 2-5 As shown, in order to further improve the stability and accuracy of the connection between the lower pressing block 1 and the upper pressing block 2, the two lower pressing blocks 1 located in the same row are connected by a connecting beam 3, and an angle groove 31 is provided on the connecting beam 3. A locking plate 4 that can move synchronously with the locking plate 22 is provided in the relative space between the two upper pressing blocks 2 located in the same row. When the staff operates the driving unit to press the locking plate 22 against the bottom wall of the lower pressing block 1, the locking plate 4 is locked into the inner side of the angle groove 31.

[0038] The combination of the positioning plate 4 and the connecting beam 3 can be located in the relative space between the lower pressing block 1 and the upper pressing block 2 in the same row to form a docking structure, thereby expanding the docking range of the container, further improving the structural strength of the lower pressing block 1 and the upper pressing block 2 when connected, and improving the stability of the connection between the two.

[0039] like Figure 5-9 As shown, specifically, the ends of the locking plates 22 are each provided with an adjusting shaft 23, the adjusting shafts 23 are each provided on the docking block 21, and a set of driven gears 24 are each provided on the adjusting shafts 23, and the two sets of driven gears 24 located on the two adjusting shafts 23 are meshed and connected. Therefore, when one set of driven gears 24 rotates synchronously with the adjusting shaft 23, the other set of driven gears 24 rotates in the opposite direction to the adjusting shaft 23 until the two locking plates 22 are synchronously moved out and moved into the inner side of the docking block 21, thereby achieving the purpose of synchronously controlling the two locking plates 22.

[0040] In order to drive the two sets of driven gears 24 and the two adjustment shafts 23 to rotate synchronously and in opposite directions, in the present application document, the driving unit includes a driving shaft 6 that passes through the docking block 21, the driving shaft 6 is parallel to the adjustment shaft 23, and the driving shaft 6 is provided with a driving gear 5 that meshes with one of the two sets of driven gears 24. The two driving shafts 6 located in the same column and distributed from front to back both pass through the upper pressing block 2 and are connected to the positioning plate 4 located in the relative space between the two upper pressing blocks 2. By controlling the rotation of one driving shaft 6 in each column, the other driving shaft 6 in the column can be controlled to rotate synchronously.

[0041] Therefore, when the driving shaft 6 rotates, the driving gear 5 can drive one of the two groups of driven gears 24 to rotate, so as to achieve the purpose of causing the two groups of driven wheels to rotate synchronously and in opposite directions, and then the two locking plates 22 can be rotated synchronously and in opposite directions to switch their own position states. During the rotation of the locking plate 22, the locking plate 4 can also rotate synchronously to switch the connection state with the connecting beam 3. When the locking plate 22 moves out of the docking block 21 and is pressed against the inner bottom wall of the lower pressing block 1, the lower pressing block 1 can be locked with the upper pressing block 2, and the locking plate 4 and the connecting beam 3 are also in a docking state. When the locking plate 22 moves into the docking block 21 and is away from the inner bottom wall of the lower pressing block 1, the lower pressing block 1 can be separated from the upper pressing block 2, and the locking plate 4 and the connecting beam 3 are also in a separated state.

[0042] Therefore, through the adjustable driving unit, the connection status of the two rows of lower pressure blocks 1 and the upper pressure blocks 2 can be quickly switched, and then the connection status of the four corners of the container can be quickly switched, reducing the time required for locking and disassembly operations point by point, and the connection status of the stacked containers is convenient for rapid disassembly of the containers, which has the advantage of portable operation.

[0043] like Figure 6-9 As shown, further, in order to facilitate the adjustment of the drive unit, in the present application document, the end of the drive shaft 6 away from the locking plate 4 extends to the outside of the upper pressure block 2, and the end of the drive shaft 6 located on the outside of the upper pressure block 2 is provided with a handle 7 that can rotate synchronously therewith. As the handle 7 rotates, the driving gear 5 and the driven gear 24 located inside the docking block 21 rotate synchronously.

[0044] Example 2: Figure 1-9As shown, on the basis of embodiment 1, the lower pressing block 1 and the upper pressing block 2 are provided with a reverse gear block 25 that can rotate in the direction opposite to the rotation direction of the driving shaft 6 on the side of the upper pressing block 2 facing the handle 7, and the reverse gear block 25 is provided with a storage sleeve 26 that can rotate synchronously with it, and a movable interception rod 27 is provided in the storage sleeve 26, and the handle 7 is provided with a receiving groove 71 that can accommodate the storage sleeve 26 and the interception rod 27. When the driving shaft 6 and the reverse gear block 25 rotate in opposite directions respectively, the storage sleeve 26 and the interception rod 27 pass through the receiving groove 71. The storage sleeve 26 and the interception rod 27 have an interception effect on the handle 7.

[0045] Specifically, a first linkage wheel 8 is provided on the driving shaft 6, and a second linkage wheel 9 is provided obliquely below the first linkage wheel 8. The first linkage wheel 8 and the second linkage wheel 9 are connected by a synchronous belt 10. A synchronous shaft 28 passing through the second linkage wheel 9 is provided on the upper pressure block 2. A synchronous gear 29 is provided at one end of the synchronous shaft 28 close to the handle 7, and the synchronous gear 29 is meshed with the reverse gear block 25.

[0046] Therefore, while the driving shaft 6 is rotated by operating the handle 7 to press the two locking plates 22 against the inner bottom wall of the lower pressing block 1, the first interlocking rotating wheel 8 and the second interlocking rotating wheel 9 arranged on the driving shaft 6 can rotate synchronously to achieve the purpose of driving the synchronous rotating shaft 28 and the synchronous gear 29 to rotate synchronously and in the same direction as the driving shaft 6. Under the meshing force of the synchronous gear 29 and the reverse gear block 25, the reverse gear block 25 rotates in the opposite direction to the driving shaft 6 and the handle 7 until the storage sleeve 26 and the intercepting rod 27 pass through the accommodating groove 71.

[0047] Furthermore, the storage sleeve 26 is threadedly connected with the interception rod 27. When the locking plate 22 is pressed against the bottom wall of the lower pressing block 1 and the positioning plate 4 is inserted into the inner side of the angle groove 31, the storage sleeve 26 and the interception rod 27 are both located below the handle 7. The interception rod 27 can be screwed out so that the end of the interception rod 27 moves to the front of the handle 7. This has a limiting effect on the handle 7, maintaining the stability of the handle 7 and the drive shaft 6, and further maintaining the stability of the connection between the locking plate 22 and the lower pressing block 1. When the lower pressing block 1 and the upper pressing block 2 are locked, the deviation of the handle 7 caused by external force impact can be avoided, and the deviation of the locking plate 22 caused by the deviation of the handle 7 and the drive shaft 6 can be effectively avoided.

[0048] Furthermore, the operation of limiting the position of the handle 7 by using the storage sleeve 26 and the intercepting rod 27 can be performed simultaneously during the operation of the handle 7 and the driving shaft 6 without the need to install additional limiting components, thus having the advantage of portable operation.

[0049] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
