[0001] The utility model relates to the technical field of automatic twist locks for containers, in particular to a fully automatic marine container twist lock. Background Technique

[0002] The greatest success of containers lies in the standardization of their products and the resulting complete set of transportation systems. It is truly one of the great miracles created by mankind to standardize a behemoth weighing dozens of tons and gradually establish a logistics system that matches ships, ports, shipping lines, roads, transfer stations, bridges, tunnels, and multimodal transport globally. The existing locks for containers are generally locked by the principle of dislocation. However, this method requires the lock to have a certain amount of movement space and is not completely locked. During the transportation of containers, there may be a situation of shaking due to loose connection, which will cause wear on the lock. In addition, a certain amount of space is required to translate the container to unlock it when disassembling the box, which is not suitable for some scenarios with insufficient space. Therefore, we propose a fully automatic marine container twist lock to solve the above problems. Content of the Utility Model

Detailed implementation manners

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1-4 , an embodiment provided by the present invention: A fully automatic twist lock for marine containers, including a container 1, on which four groups of mounting blocks 2 are fixedly installed.

[0020] A lower side of the mounting block 2 is fixedly installed with an insertion frame 3. A limiting block 4 is movably arranged in the insertion frame 3. A limiting frame 5 is arranged on an upper side of the mounting block 2. Engaging grooves 6 are formed on both the insertion frame 3 and the limiting frame 5. The limiting block 4 is engaged in the engaging groove 6. A contraction mechanism is arranged in the mounting block 2, and a guiding mechanism is arranged at the mounting block 2 and the limiting frame 5. The device is fixed by a clamping method, which increases the stability during the use of the device. In addition, the restriction is released by a contraction method, thereby increasing the convenience of disassembling the container 1.

[0021] Further, the contraction mechanism includes first moving grooves 7. Two groups of first moving grooves 7 are formed in the mounting block 2. A first rack 8 is movably inserted into the right first moving groove 7. Left and right sides of a lower end of the first rack 8 are respectively hinged with hinge rods 9. The hinge rods 9 are hinged at a central position of the limiting block 4. A gear 13 is rotatably installed between the two groups of first moving grooves 7. A second rack 14 is movably inserted into the left first moving groove 7. Both the second rack 14 and the first rack 8 are engaged with the gear 13. A second moving groove 10 is formed on one side of the right first moving groove 7. A limiting plate 11 is fixedly installed on the first rack 8. A spring 12 is arranged in the second moving groove 10. The spring 12 abuts against the limiting plate 11. This structure enables the second rack 14 to contract the limiting block 4 when a downward force is applied, thereby realizing the release of the restriction of the device. While making the connection between the containers 1 more stable, it also makes the disassembly of the container 1 more convenient.

[0022] Further, the cross-section of the limit block 4 is T-shaped. One end of the limit block 4 is sized to fit the engaging groove 6, and the other end of the limit block 4 is in contact with the inner wall of the insertion frame 3. This structure makes the engagement between the limit block 4 and the engaging groove 6 tighter and enables the limit block 4 to be stably retracted.

[0023] Further, a receiving plate 15 is fixedly installed at the upper end of the second rack 14. Guide rods 16 are fixedly installed at the four corners of the receiving plate 15. Four groups of guide grooves 17 are formed on the upper side of the mounting block 2. The guide rods 16 are movably inserted into the guide grooves 17. A limit frame 5 is fixedly installed at the upper end of the receiving plate 15. This structure makes the force on the second rack 14 more uniform and improves the lateral support force of the device.

[0024] Further, the mounting blocks 2 on the left and right sides are symmetrical. The minimum distance between the rear mounting block 2 and the edge of the container 1 is adapted to the width of the mounting block 2. This structure enables the mounting blocks 2 to engage with each other when different rows of containers 1 are placed, thereby increasing the stability of the container 1 when placing the containers 1 and saving space at the same time.

[0025] Further, the guiding mechanism includes a guiding block 18. A guiding block 18 is fixedly installed on one side of the limit frame 5. An engaging groove 6 is formed on the guiding block 18, and the position of the engaging groove 6 is opposite to the engaging groove 6 on the limit frame 5. The edge of the lower side of the mounting block 2 is rounded. This structure enables the container 1 to be conveniently installed through the guiding between the guiding block 18 and the mounting block 2 when the container 1 is hoisted, increasing the convenience of using the device.

[0026] Working principle: During use, the container 1 needs to be hoisted for installation. At this time, the hoisting mechanism will squeeze the limit frame 5 to make the limit frame 5 descend, so that the second rack 14 moves downward, drives the gear 13 to rotate through meshing with the gear 13. The rotation of the gear 13 drives the first rack 8 to rise. At this time, the limit plate 11 rises to squeeze the spring 12, so that the hinge rod 9 gradually becomes vertical, and the limit block 4 retracts into the insertion frame 3. Then the container 1 is hoisted and aligned with another container 1. At this time, the rounded corner at the lower side of the mounting block 2 will abut against the guiding block 18 to guide the container 1, so that the insertion frame 3 can be inserted into the limit frame 5. After the hoisting mechanism is removed, the limit plate 11 descends under the resilience of the spring 12, so that the first rack 8 descends, making the hinge rod 9 gradually horizontal, and the limit block 4 is re-engaged in the engaging groove 6 to complete the limit. The above is the entire working principle of the present invention.

[0027] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, in any aspect, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present utility model. Any reference signs in the claims should not be construed as limiting the claims involved.
