Detailed Description

Referring to fig. 1-5, the present invention discloses an electronic lock, including a lock body 1, an electronic control locking device 2 and a handle 3, one end of the handle 3 is pivotally installed on the lock body 1, the other end of the handle 3 is provided with an unlocking operation mechanism 4, the unlocking operation mechanism 4 is provided with an unlocking dial wheel 41 which is rotatably fitted on the handle 3 and an operation mechanism for driving the dial wheel 41 to rotate, the operation mechanism can be a mechanical lock cylinder 42, a knob and a linkage component thereof, a slide button and a linkage component thereof, etc., the structure of the operation mechanism is conventional in the art, so the detailed structure is not described again, in order to consider the anti-theft performance, the embodiment adopts the mechanical lock cylinder 42 design, the electronic control locking device 2 includes a lock tongue 21 and an unlocking linkage component 22 for linking the lock tongue 21 and the dial wheel 41, the lock tongue 21 is driven by an electric actuator, the electric actuator is conventional in, the lock body 1 is provided with a avoiding space 1-1 for the thumb wheel 41 to swing along with the handle 3 to separate from the lock body 1 when the thumb wheel 41 is positioned at the tail end of the unlocking stroke, the lock tongue 21 is provided with a hook 211, the locking part 31 is provided with a buckle groove 311 which is in buckle/release fit with the hook 211, the lock body 1 is provided with a jacking part 11 which is in corresponding rotating stroke of the thumb wheel 41 and is in push fit with the thumb wheel 41, the jacking part 11 at least partially extends to the unlocking stroke of the thumb wheel 41, and one end of the jacking part 11 is stopped at the avoiding space 1-1, in the process that the thumb wheel 41 rotates from the starting end of the unlocking stroke to the avoiding space 1-1, the thumb wheel 41 is pressed by the pressing part 11 to form the pressing handle 3, so that the hook 211 is disengaged from the buckle groove 311. When the unlocking operation mechanism drives the thumb wheel to rotate to perform unlocking action, the thumb wheel rotates to the jacking part and finishes the pressing action on the handle through jacking of the jacking part, the handle does not need to be pressed additionally to perform tripping operation of the clamping hook and the clamping groove, and the unlocking operation of the unlocking operation mechanism is simpler and more convenient.

The push portion 11 has an extension 111 extending from the end position of the unlocking stroke to the start position of the unlocking stroke in the direction of the unlocking stroke in the rotation direction of the dial 41. When the thumb wheel is driven to rotate to unlock, the thumb wheel enters the extending section of the jacking portion in advance to press the handle to move, then the thumb wheel is kept in a jacking state by the jacking portion and enters an unlocking stroke until the thumb wheel is transited to an avoiding space position to complete unlocking movement, and therefore the movement is smooth and reliable.

The pushing portion is more smoothly and reliably pushed into the pushing wheel, and the surface of the pushing portion 11, which is in pushing fit with the pushing wheel 41, is an inclined surface 11-1. The design of the inclined surface 11-1 is convenient for the thumb wheel to enter and exit the jacking portion 11. The thumb wheel 41 is provided with a slope surface 411 correspondingly matched with the jacking portion 11, and the low position of the slope surface 411 extends to the edge of one side corresponding to the rotation direction of the thumb wheel 41. The slope design on the thumb wheel is convenient for the edge of the thumb wheel to enter the jacking portion, and then the handle is gradually pressed along with the rotation of the thumb wheel, so that the action process is softer and smoother.

For more convenient unlocking action, the dial wheel can complete unlocking operation when being allowed to act in both the anticlockwise direction and the clockwise direction, so that the lock body 1 is provided with the jacking parts 11 which are respectively arranged at two sides of the avoiding space 1-1 along the rotating direction of the dial wheel 41. The symmetrical layout is realized, and the poking wheel can complete corresponding unlocking action when rotating clockwise or anticlockwise.

Two slope surfaces 411 which are symmetrically arranged are arranged on the corresponding thumb wheel 41, so that the surfaces of the thumb wheel corresponding to the jacking parts are high in the middle and low on two sides. The thumb wheel can better enter the corresponding jacking part when rotating in the corresponding direction.
