Description
Technical field
The utility model relates to a kind of lockset using on strongbox, safety cabinet or the supermarket locker of valuables that is adapted at depositing, and relates in particular to a kind of electromagnetic lock.
Background technology
The existing lockset for strongbox, safety cabinet or cashbox door, generally be divided into mechanical lock and the large class of electronic lock two, for mechanical lock, generally by locking bar or lock pin that will be connected with locking bar are inserted in the spacing hole that latch board is corresponding and realize the restriction to latch board, and also drive thus latch board flexible.Yet in actual use,, if its lock core violence nature ground is inwardly struck de-, the connected lock pin of its locking bar or locking bar will depart from latch board, thereby removes the restriction to latch board.
On the other hand, it is comparatively common at present on strongbox, adopting the combination of mechanical lock and electronic lock, latch board wherein can be respectively by mechanical lock, the executing agency of electronic lock is spacing, usually, wherein the execution unit of electronic lock is the electromagnetic valve lock for the armature that can reset, under electromagnetic valve lock power failure state, its armature or insert or embed in the groove that latch board arranges at corresponding site with the lock pin of this armature interlock, make this latch board spacing, only have after the confirmation such as the password of electronic lock or fingerprint, electromagnet energising, its armature is inhaled, thereby remove the locking to latch board, now, with key operated mechanical lock, can drive latch board inside contract and unblank.A kind of combined mechanoelectric lock as disclosed in the patent No. Chinese utility model patent < < combined mechanoelectric lock > > that is ZL02215701.8 (notification number is CN2525181Y).
Yet just because of the armature of electromagnetic valve lock is mobilizable, and electric armature is all directly to contact with latch board, overexerts once turning handle, latch board just can directly clash into armature, damages armature or directly slips over armature, and door is opened, and causes potential safety hazard; In addition, existing electromagnetic lock just plays the effect of locking latch board, and the unlatching of latch board needs other handle arrangement, and this certainly will have the door body that handle protrudes locker outward, causes locker to take up space greatly.
Summary of the invention
Technical problem to be solved in the utility model is the electromagnetic lock that provides a kind of armature directly not contact with latch assembly for above-mentioned prior art present situation, this electromagnetic lock not only plays the effect of pinning latch assembly simultaneously, it is direct opened lock bolt assemblies also, without the handle of opened lock bolt assemblies is additionally set on cabinet door or chamber door.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of electromagnetic lock, comprise lock housing, and in lock housing, be provided with the electromagnetic valve lock with telescopic armature, armature keeps overhanging trend by the first spring supporting; It is characterized in that: in described lock housing, rotate and be provided with a clamp, one end of clamp and described armature are hinged; In lock housing, be also provided with the axis of rotation that can rotate around self axis, be arranged with shift fork and the lock banking stop that can rotate with axis of rotation on axis of rotation, a side of lock banking stop is provided with the draw-in groove coordinating with described clamp; On axis of rotation, be also arranged with and act on lock banking stop and lock banking stop is had towards the torsion spring of unlocking condition direction deflection trend; When shift fork is subject to External Force Acting to rotate to lock position from unlocking condition, the deflection under the first spring action of described clamp slips in described draw-in groove lock banking stop is locked; At electromagnetic valve lock, obtain under the electric state inside contracting with moving armature, described clamp overcomes the reverse deflection of the first spring force and skids off described draw-in groove, and meanwhile, described lock banking stop synchronously drives axis of rotation direction deflection towards unlocking condition together with shift fork under the effect of torsion spring.
As improvement, in above-mentioned lock housing, be also provided with microswitch, this microswitch coordinates with described clamp, and the deflection of clamp can touch described microswitch.Microswitch is set can be connected with display structure, according to microswitch, whether by clamp, triggered and send coherent signal, microswitch can be touched after unblanking, also can be touched after locking, sort signal can be wireless signal, also can be the state displaying symbol being directly presented on display screen, can tell the cabinet door of this locker of custodian to be in the lock state or unlocking condition, for the security management setting of locker provides possibility.
The above-mentioned lock banking stop side face that is positioned at described draw-in groove bottom is curved, and the top of draw-in groove has the rib that protrudes lock banking stop side face.The deflection of lock banking stop makes curved lock banking stop outer peripheral face can promote clamp to move outward, when clamp moving to draw-in groove over against time, clamp resets and snaps in draw-in groove under the first spring action, as excessive towards the lock position anglec of rotation under axis of rotation drives in lock banking stop, rib can be conflicted with clamp, stops the further deflection of lock banking stop, and lock banking stop resets under torsion spring effect, until clamp moving to draw-in groove over against time, clamp resets and snaps in draw-in groove under the first spring action.
For making this electromagnetic lock there is emergency opening function, in above-mentioned lock housing, be provided with the emergent unlocking pull bar of slippage up and down, the inner of this emergent unlocking pull bar is connected with described clamp, the outer end of emergent unlocking pull bar is stretched out lock housing and is driven and slippage up and down for mechanical emergency lock, is provided with and acts on emergent unlocking pull bar and make it keep the second spring of the trend of moving in lock housing.Emergent unlocking pull bar is set and can, in the situation that electromagnetic valve lock damages, by mechanical emergency, locks this electromagnetic lock of emergency opening.
The sidepiece of above-mentioned clamp has the connecting portion extending to a side, on described emergent unlocking pull bar, have bar hole, described connecting portion is through hinged with described armature after this bar hole, the top of described clamp has upwardly extending card division, this card division coordinates with described draw-in groove, and the bottom of described clamp has the touch part coordinating with microswitch to downward-extension.When emergent unlocking pull bar moves down, the upper inwall of bar hole can promote the super direction deflection of unblanking of clamp.
In above-mentioned lock housing, be fixed with the fixed head that wears installation for axis of rotation.Because the sidewall of lock housing is thinner, can not provide firm installation position to axis of rotation, the setting of fixed head provides more safe installation position to axis of rotation.
On above-mentioned fixed head, have the chute that described card division is retrained.
Compared with prior art, the utility model has the advantage of: armature is associated with latch board by clamp, lock banking stop, axis of rotation, shift fork, latch board can directly not clash into armature and damage electromagnetic valve lock, the safety that has further improved electromagnetic lock; In addition after electromagnetic valve lock is unblanked, the locking of clamp contact to lock banking stop, lock banking stop driven rotary axle and shift fork deflection and open locker under torsion spring effect, open locker without handle drives latch board is additionally set, and this electromagnetic lock has locking simultaneously and opens locker function.
