All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, a container corner fitting structure capable of automatically picking up a lock comprises a first frame 1 fixedly installed at four corners of the bottom end of a container and a second frame 4 movably connected in an inner cavity of the first frame 1, as shown in fig. 4, two sides of the inner cavity of the first frame 1 are respectively provided with a group of first grooves 3, a group of linkage blocks 2 with isosceles triangle-shaped cross sections are fixedly installed in the first grooves 3, as shown in fig. 5-6, two sides of the top of the inner cavity of the second frame 4 are respectively provided with a group of slide rails 5, the bottom of the inner cavity of the second frame 4 is movably clamped with a third frame 6, two ends of the third frame 6 are respectively provided with a second groove 7, four corners of the slide rails 5 on the second frame 4 and located at the top of the inner cavity of the second frame 4 are respectively and movably connected with a group of driving sliders 8, as shown in fig. 2, one end of the driving slider 8 is in transmission connection with the inner side of the second frame 4 through a pressure spring 14, so that the two corresponding sets of driving sliders 8 keep a mutually attached state when the driving sliders are not stressed, the two sets of second frames 4 on the left side are just positioned above the left side linkage block 2 on the first frame 1, and the two sets of second frames 4 on the right side are just positioned above the right side linkage block 2 on the first frame 1.

As shown in fig. 7, in the present technical solution, a sliding groove 9 movably sleeved with the sliding rail 5 on the second frame 4 is provided at the top of one side of the driving slider 8, a first inclined plane 10 having the same inclination angle as the two sides of the linkage block 2 on the first frame 1 is provided at the inner side of the driving slider 8, a second inclined plane 11 is provided at the bottom of one side of the driving slider 8, and a movable ball 13 therein can swing when the first frame 1 moves up in cooperation with the first groove 3, and a locking block 12 is fixedly installed at the other side of the driving slider 8 for clamping a locking chuck on the twist lock mechanism.

As shown in fig. 3, in the present embodiment, the surface of the second groove 7 on the third frame 6 is provided with a movable ball 13, and the outer surface of the movable ball 13 is respectively contacted with the end surface of the driving slider 8 and the first groove 3 on the inner wall of the first frame 1, and the movable ball 13 is arranged to control the relative moving state among the first frame 1, the second frame 4 and the third frame 6 under different stress states.

In this technical solution, when the third frame 6 falls naturally under the action of gravity, the movable ball 13 in the second groove 7 is in a loose state, and when the third frame is stressed and kept flush with the bottom end of the first frame 1, the movable ball 13 in the second groove 7 is in a clamped state under the action of the first groove 3 on the first frame 1 and the second inclined plane 11 on the driving slider 8.

In the technical scheme, when the first frame 1 moves upwards, the maximum distance of the two groups of driving slide blocks 8 at the corresponding positions driven by the upper linkage block 2 to move towards two sides can force the locking chucks on the twist locks matched with the first frame to fall off.

In the technical scheme, a certain gap is kept between the second inclined surface 11 on the driving slide block 8 and the end surface of the linkage block 2 on the first frame 1 in an initial state, so that the movable ball 13 on the first frame 1 can be loosened firstly when the first frame moves upwards.

The use method and the working principle of the embodiment are as follows:

when the container with the corner fitting structure is placed in a warehouse, the third frame 6 on the corner fitting structure is forced to move upwards until the bottom end of the third frame is flush with the bottom end of the first frame 1, and the first frame 1 is always forced downwards by the gravity of the container, so that the movable ball 13 in the second groove 7 on the third frame is forced to be in contact with and completely clamped between the second inclined plane 11 on the driving slide block 8 and the inner wall of the first groove 3 on the first frame 1, and the first frame 1, the second frame 4 and the third frame 6 can form a relatively stable integral structure, and the container is fixed in the warehouse by a twist lock mechanism under the action of the locking block 12 on the driving slide block 8;

when the container is unloaded by using the hoisting equipment, the first frame 1 on the container is pulled upwards and moves upwards along with the pulling force, so that the movable ball 13 on the container is loosened under the action of the first groove 3 on the first frame 1, and further, the third frame 6 and the driving slide block 8 are loosened and the second frame 4 is forced to move downwards;

in the process of continuous upward movement of the first frame 1, the linkage block 2 on the first frame and the first inclined surface 10 on the driving slide block 8 are contacted, and then the two groups of driving slide blocks 8 on the corresponding positions are driven to move outwards and compress the corresponding pressure springs 14, so that the gap between the two groups of locking blocks 12 on the corresponding positions is gradually increased until the locking chucks on the twist-lock mechanism can be disengaged, and then the locking action on the container can be automatically released by applying upward pulling force on the container when the container is unloaded.
