Please refer to fig. 1 to 4. It should be understood that in the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate the position or positional relationship based on the position or positional relationship shown in the drawings, or the position or positional relationship that the product of the present invention is usually placed when in use, and are only for convenience of describing the present invention and simplifying the description, but do not indicate or imply that the device or element to which the term refers must have a specific position, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," "third," and the like are used solely to distinguish one from another, and are not to be construed as indicating or implying relative importance. The terms "horizontal", "vertical", "overhang" and the like do not imply that the components are required to be absolutely horizontal or overhang, but may be slightly inclined. For example, "horizontal" merely means that the direction is more horizontal than "vertical" and does not mean that the structure must be perfectly horizontal, but may be slightly inclined.

In the description of the present invention, it should be further noted that, unless otherwise explicitly stated or limited, the terms "disposed," "mounted," "connected," and "connected" are to be construed broadly and may include, for example, a fixed connection, a detachable connection, an integral connection, a mechanical connection, an electrical connection, a direct connection, an indirect connection via an intermediate medium, and a connection between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Example (b): as shown in fig. 1 to 4, an electronic control lock structure of a drawer 1 includes a drawer 1, an electronic control lock mechanism is disposed at a tail of the drawer 1, the electronic control lock mechanism includes a base 2, a lock body 3 is disposed on the base 2, the lock body 3 includes a movable block 31, a hook 32, a connecting rod 33 and a roller 34, the roller 34 is coaxially connected with an output shaft of a driving motor, the movable block 31 is rotatably disposed on the base 2 through a first rotating shaft 35, the hook 32 and the connecting rod 33 are rotatably disposed on the movable block 31 through a second rotating shaft 36, and meanwhile, a top of the connecting rod 33 is overlapped with a surface of the roller 34; the bottom of the drawer 1 is provided with a lock rod 4, and the tail end of the lock rod 4 is provided with a lock block 5 corresponding to the hook 32; the first rotating shaft 35 and the second rotating shaft 36 are both sleeved with clamp springs.

The automatically controlled keying of drawer 1 of this scheme design constructs, can the opening and closing of automatic control drawer 1, and concrete theory of operation does: as shown in fig. 2, the drawer 1 is in a locked state, at this time, the locking block 5 at the tail end of the locking lever 4 at the top of the drawer 1 is correspondingly clamped with the hook 32, and the top of the connecting rod 33 abuts against the bottommost position of the roller 34; when the drawer needs to be unlocked, as shown in fig. 3, the driving motor controls the roller 34 to rotate, the roller 34 drives the connecting rod 33 to move upwards by the tangential centripetal force while rotating, the connecting rod 33 drives the movable block 31 to turn upwards, at this time, the hook 32 is lifted, the locking block 5 at the tail part of the locking rod 4 is not limited, and the drawer 1 can be unlocked and pulled out; when the drawer 1 needs to be locked, as shown in fig. 4, the locking block 5 at the front end of the locking rod 4 drives the hook 32 to turn upwards while being pushed, at this time, the clamp spring on the second rotating shaft 36 is perpendicular to the stretched state, and after the locking block 5 is pushed into the inner side of the hook 32, the clamp spring can drive the hook 32 to automatically reset under the condition of no external force, meanwhile, the hook 32 is clamped with the locking rod 4, and the drawer 1 is locked.

The preferred embodiment is as follows:

the surface of the roller 34 is provided with convex teeth; the teeth increase the friction between the top of the link 33 and the surface of the roller 34, so that the roller 34 can lift the link 33 more easily.
