Detailed Description

The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.

As shown in fig. 1 to 4, the novel full-automatic lock for containers comprises a lock body 10, wherein an upper hook 20 is arranged at the upper end of the lock body 10, a locking platform 30 is convexly arranged at the middle part, and a lower hook 40 is arranged at the lower end.

Specifically, in the novel full-automatic container lock, a clamping groove 11 is formed between the upper hook head 20 and the lock platform 30 and used for clamping and locking the corner of the upper container. The top surface of the lock platform 30 is provided with an accommodating groove 31, and the accommodating groove 31 and the card slot 11 are arranged in a staggered manner; a stop block 32 is rotationally connected in the containing groove 31; a second elastic piece 33 is connected between the stopper 32 and the inner wall of the containing groove 31; the stopper 32 can be rotated to protrude out of the receiving groove 31 by the elastic force of the second elastic member 33. Preferably, the second elastic member 32 is a spring.

Further, a guide block 34 for guiding the stopper 32 to rotate is provided in the housing groove 31.

In the novel full-automatic container lock, a movable block 50 is arranged on one side of a lock body 10; the movable block 50 is arranged close to the head of the lower hook head 40, and the lower end of the movable block is rotatably connected with the lock body 10 through a pin shaft 12; a first elastic member 60 is connected between the movable block 50 and the lock body 10; the lock body 10 is also provided with a limiting part 13; the movable block 50 can rotate to abut against the limiting part 13 under the elastic force of the first elastic piece 60, and the side part of the movable block extends out of the head part of the lower hook head 40; in the locked state, the lower hook head 40 extends into the container, and the movable block 50 is in hook-lock connection with the corner of the container.

Wherein, the side of the movable block 50 far away from the lock body 10 is provided with a guide surface 52 and a first locking surface 51 which form an included angle with each other, and the first locking surface 51 is positioned above the guide surface 52 and smoothly transits with the guide surface 52. When the container is inserted, the corner presses the movable block 50, and the movable block 50 rotates toward the lock body 10 under the guiding action of the guiding surface 52, so that the container can be smoothly inserted into the container. After entering the container, the movable block 50 is automatically ejected by the first elastic member 60, and the first locking surface 51 is in hook-and-lock connection with the corner of the container. Preferably, the first elastic member 60 is a spring.

In the novel full-automatic container lock, the tail part of the lower hook head 40 protrudes outwards to form a hook part 41. The hook portion 41 has a second locking surface 411 for locking the corner of the box, and the second locking surface 411 is an inclined surface and forms an included angle with the first locking surface 51. Because the lower hook head 40 adopts a double-hook head design, in the using process, once the locking between the movable block 50 and the box corner fails, one end of the lower hook head 40 can hook the box corner, and the lock can be prevented from being opened. Therefore, the lower hook head 40 and the movable block 50 are matched for use, so that double locking of the box corner can be realized, and the situation that the box is separated and falls due to the fact that the lock is accidentally opened in the using process is effectively prevented.

When the novel container full-automatic lock of the utility model locks a container, as shown in fig. 5-7, the lock body 10 moves downwards to drive the movable block 50 and the lower hook head 40 to move downwards together to be contacted with the container corner; and the box corner continues to move downwards, the movable block 50 is extruded by the box corner, the movable block 50 rotates towards the lock body 10 under the guiding action of the guide surface 52, after the lower hook head 40 completely enters the box corner, the movable block 50 automatically pops up, and the first locking surface 51 of the movable block 50 is locked with the box corner.

In the locked state, the box corner acts on the first locking surface 51 of the movable block 50, and the force direction of the movable block 50 is perpendicular to the first locking surface 51, so that the movable block 50 cannot rotate relative to the lock body 10 at this time.

When unlocking, as shown in fig. 8-10, first, the lock body 10 moves upward along the first locking surface 51 until the hook portion 41 of the lower hook head 40 contacts the corner of the box, and at this time, the guide surface 52 of the movable block 50 contacts the corner of the box; then, the lock body 10 moves upward along the second locking surface 411, and at the same time, the movable block 50 is pressed by the corner of the container to rotate toward the lock body 10, and finally the lower hook 40 and the movable block 50 are completely separated from the container, thereby completing the unlocking operation.

It can be seen that, the utility model discloses a novel full-automatic lock of container utilizes can rotate under the effect of first elastic component 60 and stretches out down the movable block 50 of the head of gib head 40 and the coupler lock is connected between the case angle of container, can effectively improve the condition that the locking became invalid, has improved the security of using. In addition, the contact area between the lock and the corner of the container is increased through the movable block 50, the problem of concentrated stress of the corner is solved, and the risk of damaging the corner is reduced.

The technical principle of the present invention is described above with reference to specific embodiments. The description is made for the purpose of illustrating the principles of the invention and should not be construed in any way as limiting the scope of the invention. Based on the explanations herein, those skilled in the art will be able to conceive of other embodiments of the present invention without any inventive effort, which would fall within the scope of the present invention.
