Detailed Description

Referring to fig. 1-7, a first embodiment;

the utility model discloses an electronic cabinet lock, including lock shell 1 and activity set up the handle 2 on lock shell 1, be equipped with the handle groove 11 of handle 2 lock on lock shell 1, be equipped with the automatically controlled locking device who is used for locking the handle in the lock shell 1, be equipped with supplementary unblock operating device 3 and through supplementary unblock operating device 3 driven unblock piece 4 on handle 2, as the technical personnel in the field are familiar with, supplementary unblock operating device 3 can be lock core, knob, push button or button etc. for the theftproof nature of realization mechanical operation mechanism, the lock core design is adopted to the priority, automatically controlled locking device includes self-sustaining electro-magnet 5, self-sustaining electro-magnet 5 is conventional part among the prior art, can be under solenoid power-off state, and the iron core keeps stretching out state or retracting state, reaches the flexible action of drive iron core (solenoid and permanent magnet are not shown in the figure when being switched on through solenoid forward, reverse), therefore, detailed description of the structure is omitted, the iron core 51 of the self-holding electromagnet 5 has a locking end 52 for locking/unlocking the handle, the lock case 1 is provided with a blocking surface 12 and an unlocking linkage member 6 correspondingly matched with the locking end 52, the unlocking member 4 pushes the unlocking linkage member 6 to unlock the handle at a position where the locking end 52 is unlocked, and the unlocking member 4 enters the position corresponding to the blocking surface 12, so that the unlocking member 4 is matched with the blocking surface 12 in a stopping manner in the opening direction of the handle 2 (as shown in fig. 4). When the locking end of the auxiliary unlocking operating mechanism needs to be unlocked, the unlocking piece enters the position of a blocking surface in the lock shell and is blocked by the blocking surface to lock the handle, the handle needs to be opened, the unlocking piece and the blocking surface need to be further unlocked, therefore, under the condition that the self-holding electromagnet normally runs, when the unlocking piece exits from the blocking surface, the unlocking piece 4 releases the pushing unlocking linkage piece 5, the locking end can be locked again under the action of the iron core, and the auxiliary unlocking mode cannot be used when the electric control locking device normally works; under the condition that the self-holding electromagnet is powered off, the iron core is kept in an unlocking state under the action of the self-holding electromagnet and the condition that the locking end of the iron core is unlocked through the unlocking linkage piece 5, then the unlocking piece exits from the blocking surface, and the handle can be opened; the electronic lock has the function that the electronic lock can be unlocked only when the electric control locking device fails in daily automatic unlocking and mechanical unlocking. The locking end of the self-holding electromagnet is matched with the unlocking piece through the unlocking linkage piece, the locking end and the unlocking piece are separated in the spatial position, when the unlocking piece unlocks the locking end to lock the handle, the unlocking piece needs to enter the blocking surface position to lock the handle, and therefore the safety and reliability of the lockset are improved, and the prying resistance is improved. And under the design of face that blocks, can cooperate and reach the locking to the handle with the deblocking piece, realize that the rack lock also can use under as the mechanical lock condition.

In order to reduce the power consumption of the electric control locking device during operation, the unlocking linkage member 6 is provided with the toggle block 61, the locking end 52 is provided with a linkage lug 521 which is in pushing fit with the toggle block 61, the unlocking linkage member 6 is provided with an unlocking position (such as the unlocking linkage member 6 shown in fig. 4) and a closing position (such as the unlocking linkage member 6 shown in fig. 2 and 3) along the moving direction, when the unlocking member 4 pushes the unlocking linkage member 6 to the unlocking position, the toggle block 61 pushes the linkage lug 521 to drive the locking end 52 to unlock the handle 2, and the unlocking linkage member 6 is matched with a reset mechanism which provides a reset driving force for the unlocking linkage member 6 to tend to the closing position from the unlocking position. The reset mechanism comprises a reset spring 6-1, one end of the reset spring 6-1 is abutted against the unlocking linkage piece 6, and the other end of the reset spring 6-1 is abutted against the lock shell 1. Certainly as the utility model discloses feasible scheme, canceling release mechanical system can also adopt the magnetic pole to repel each other and provide the drive power that resets, nevertheless adopts the spring design, has simple structure, the reliable and stable advantage of work. When the electric control locking device works, the unlocking linkage piece and the locking end are in pushing fit to realize linkage, the unlocking linkage piece is reset from an unlocking position to a closing position through the reset mechanism, and then the locking end can be separated from the unlocking linkage piece and is electrically driven by the electric control locking device to complete locking and unlocking actions, so that the power consumption is reduced. Under the guidance of the essential spirit of the present invention, the person skilled in the art can adopt the design of the unlocking linkage piece and the locking end connection follow-up structure without considering the power consumption.

The unlocking linkage member 6 is further provided with a reset shifting block 62, the shifting block 61 and the reset shifting block 62 are arranged at intervals along the extension direction of the iron core 51 to form a movable interval I, the linkage convex block 521 extends into the movable interval I, the unlocking linkage member 6 is limited at a closed position (the position of the unlocking linkage member 6 shown in fig. 2 and 3) by a handle 2 in a state of being buckled on the lock shell 1, as shown in the embodiment of the figure, the end part of the unlocking linkage member is abutted against the unlocking member to be limited at the closed position, of course, the end part of the unlocking linkage member can be directly abutted against the outer surface of the handle to be limited at the closed position, and the movable interval I of the unlocking linkage convex block 521 covers the movable stroke of the locking/unlocking action of the locking end 52 when the unlocking linkage member 6 is at the closed position, namely, when the locking end 52 is in the locking and unlocking action processes, the linkage protrusion 521 is free to move within the movement interval I, the unlocking linkage 6 is driven by the reset driving force of the reset mechanism to have an open position (the unlocking linkage 6 position shown in fig. 5), the handle 2 in the open state on the lock case 1 releases the limitation on the unlocking linkage 6 so as to form the unlocking linkage 6, the unlocking linkage 6 moves to the open position through the reset mechanism, the unlocking linkage 6 moves to the open position and pushes the linkage protrusion 521 through the reset shifting block 62 so that the locking end 52 is in the position of locking the handle 2. When the handle is opened from the lock shell, the unlocking linkage piece moves to an opening and closing position under the action of the reset driving force of the reset mechanism, and meanwhile, the reset shifting block shifts the linkage convex block to enable the locking end to be located at a locking position for locking the handle. The locking end 52 is touched and pressed by the handle 2 to move from the position of the locking handle 2 to the position of the unlocking handle 2 for avoiding, and due to the fact that the avoiding stroke is small, the iron core can reset to the position of the locking handle 2 under the action of resetting force after the touch pressure of the locking end 52 is relieved. The structure for avoiding displacement when the handle 2 is pressed against the locking end 52 may be a slope surface 5222 provided on the locking end 52, or/and a slope surface 212 provided on a portion of the handle 2 that is in locking engagement with the locking end 52.
