Abstract
The utility model belongs to an automatic safe lockup device comprising a hand button portion, a latch 1, a handle 9, an electromagnetic lock 11, and a handle gear 2 which is connected with the handle 9, wherein, the latch 1 is provided with a rack 10 which is meshed with the handle gear 2, and the handle 9 is provided with a switch mechanism. The utility model has the advantages of simple structure, little friction and flexible and reliable latching action. The switch mechanism of the handle 9 comprises a clamping pin 13, a connecting rod 12 of the clamping pin and a spring 15. The switch mechanism on the handle 9 prevents the handle 9 against non-manual rotation, thus increasing the reliability of the lockup of illegal opening.
Description
The utility model belongs to a kind of safety cabinet and arrests locking device automatically.
Along with the renewal of technology, more and more higher to the requirement of safety cabinet anti-theft alarm function.In the prior art, having employing to arrest device automatically carries out improved to safety cabinet.Lock wherein insert by with rotating disk that handle is connected on the cam slideway drive, frictional force is bigger, can cause after the wearing and tearing move unreliable; Sometimes available in addition fork implement turn handle, and cause chance without the hand-screw fixed handle.
Task of the present utility model provides a kind of safety cabinet simple in structure, that the reliable and non-hand-machine of mortise lock flexible movements can lack and arrests locking device automatically.
Task of the present utility model is achieved by the following scheme: safety cabinet is arrested locking device automatically and is comprised hand button part, lock slotting (1), handle (9) and electromagnetic locking device (11).It also comprises the handle gear (2) that is connected with handle (9), and lock is inserted on (1) has the tooth bar (10) that is meshed with handle gear (2), and handle (9) is provided with switching mechanism.The switching mechanism of handle (9) comprises bayonet lock (13), bayonet lock connecting rod (12) and spring (15), bayonet lock connecting rod (12) and spring (15) are loaded in the handle (9), bayonet lock (13) is hinged with bayonet lock connecting rod (12), and bayonet lock (13) mortise lock is in the lockhole of machine core board (14).
The utility model is realized the mortise lock action owing to the pinion and rack that adopts handle gear (2) and tooth bar (10) to form drives lock slotting (1), has simple in structure, little, the reliable advantage of mortise lock flexible movements of friction.On handle (9), be provided with switching mechanism in addition, thereby prevented the non-manual rotation of handle (9), increased the reliability that illegal unlatching is arrested.

Embodiment:
As shown in Figure 1, 2, 3, safety cabinet is arrested locking device automatically and is comprised that hand button part, lock insert (1), handle (9) and electromagnetic locking device (11).It also comprises the handle gear (2) that is connected with handle (9), and lock is inserted on (1) has the tooth bar (10) that is meshed with handle gear (2), and handle (9) is provided with switching mechanism.Machine core board (14) is fixed on the inboard of safe door outside plate (3).
The hand button comprises that partly drive motors (21), reduction gearing are to (22), hand buckle teeth wheel (23), hand button are to (24) and hand button rotating shaft (25), the hand button is to having the tooth that is meshed with hand buckle teeth wheel (23) on (24), the hand button can rotate (24) in thorny button rotating shaft (25).Handle (9) is located in the rotating cylinder (91), and the shaft support of rotating cylinder (91) is on machine core board (14), and handle gear (2) is fixed in the rotating shaft of rotating cylinder (91), and the tooth bar (10) on three locks slotting (1) is meshed with handle gear (2) simultaneously.The hand button is to (24) the hidden inboard of safe door outside plate (3) and the gap location of rotating cylinder (91) of being located at.Be provided with fore shaft on any one lock slotting (1), the stop pin of electromagnetic locking device (11) is inserted in the fore shaft, and stop pin and fore shaft have small preset clearance.
The switching mechanism of handle (9) comprises bayonet lock (13), bayonet lock connecting rod (12) and spring (15), bayonet lock connecting rod (12) and spring (15) are loaded in the handle (9), and bayonet lock (13) is hinged with bayonet lock connecting rod (12), and bayonet lock (13) mortise lock is in the lockhole of machine core board (14).
As shown in Figure 4, control circuit adopts dc source (31) power supply, and it comprises electronic cipher switch (32), and microswitch K1 arrests gauge tap K2, arrests alarm switch K3 and alarm (33).In order to improve the integrated alarm function, can with arrest alarm switch K3 access in parallel overtemperature sensitive switch (34), vibrating sensing switch (35) or other class switch.
In use, the opening safety cabinet is at first imported unlocking cipher if desired, and electronic cipher switch this moment (32) is connected circuit.At this moment electromagnetic locking device (11) energising work, the stop pin of pulling electromagnetic locking device (11) is away from the fore shaft on the lock slotting (1), simultaneously by arresting the power supply of gauge tap K2 cut-out drive motors (21).Hand is stretched in the rotating cylinder (91), hold handle (9), simultaneously Push switch mechanism, make bayonet lock (13) leave the lockhole of machine core board (14), turning handle (9) drives the lock slotting (1) with tooth bar (10) by handle gear (2) and moves, and just can open the cabinet door of safety cabinet this moment.If during illegal opening safety cabinet, because hand must be stretched in the rotating cylinder (91) Push switch mechanism to make bayonet lock (13) leave the lockhole of machine core board (14), then can make lock insert (1) as turning handle (9) and do micro displacement according to preset clearance this moment, and shake-up microswitch K1, drive motors (21) work of switching on immediately, by reduction gearing (22) and hand buckle teeth wheel (23) are driven the hand button to (24) thorny button rotating shafts (25) quick-make, pin wrist, the hand button is arrested alarm switch K3 and alarm (33) is reported to the police (24) shake-up simultaneously.
