Description

Double electronic cipher safe

The utility model relates to a kind of burglary insurance device, specifically a kind of duplex electronic cipher safe.

Existing strongbox is that handgrip opens the door, mechanical cipher, and cylinder lock also is with warning function.Recently existing electronic safe comes out, and it has increased code keypad on Qi Menbi, capable of automatic alarm, but does not have big broken on the case lock and the handle that opens the door.The shortcoming of this class strongbox is: mechanical cipher is easily decrypted, and inconvenience is used; Its code keypad of electronic safe exposes easily and goes to pot, and unrelated person closes conveniently by causing damage.In addition, its unlocking mechanism is relay control bayonet lock cylinder lock or is the relay system kayser that this lock is to the power requirement height, require also high to relay, for example: require the suction-combining force to want big, otherwise just inhale motionless door lock, and open the door and still need rotary door up knob or pulling handle.

The purpose of this utility model is: overcome existing machinery combination lock function singleness, easily decrypted shortcoming simultaneously also exposes and easily is damaged and its power requirement is high and unpack smooth problem in order to solve electronic cipher case keyboard.

Being constructed as follows of described utility model: double-deck casing is filled with fire proofing material in (1), from opening door (4) interior front motor-driven electric lock (7) is installed, from opening moving (4) inside back installation two set bolts (3) in the outside, spring door bolt (5) casing (1) back are installed, the case inner bottom part has its interior battery of placing of a box body (15), charging equipment and crypto-alarm circuit, one deck cover plate is arranged on it, itself and case inner matter space are separated, casing (1) front panel bottom center has a drawer type key box (8), place code keypad (10) in this drawer, charge power supply indicator lamp (11) and charging have been installed have finished indicator lamp (12), power safety seat (13), power line (14), the drawer outside is equipped with a drawer-lock (9).

Electric lock (7) is a kind of by motor-driven lock, it comprises shell, locking bar, card frame, its architectural feature is: in the shell (21) of described electric lock (7) micromachine (22) is installed, drive screw (23) passes the screw of inserted link nut (24) central authorities, stopping bar behind its rear portion (29) is fixed in the rotating shaft of micromachine (22), and stopping bar (26) was contained on the lock body shell (21) before it was anterior; The two ends up and down of inserted link nut (24) respectively are fixed with a locking bar (25) and foot piece (27), foot piece (27) pass card frame (28) and can the card frame in about move freely.When receiving the password unlocking signal, micromachine (22) is according to the uncaging time of setting (as 2 seconds) the 2 seconds kinds that turn clockwise, the back preceding stopping bar of stopping bar (29) drive screw (23) this moment (26) rotates simultaneously, inserted link nut (24) under the effect of drive screw (23) to left movement, be fixed in locking bar (25) on the inserted link nut (24), foot piece (27) together to left movement, locking bar (25) just withdraws from from the preformed hole of chamber door frame, after withdrawing from from doorframe fully, chamber door automatically springs open under the effect of spring door bolt (5); Motor continues to rotate to inserted link nut (24) when withdrawing from the spiral shell mosquito of drive screw (23) fully, and just be in slipping state and no longer be moved to the left, after the 2 second time of electric current of unblanking arrives, the motor stall, unlocking action finishes.The effect of card frame (28) is can guarantee that foot piece (27) does not rock so that the steady honest operation of locking bar (25) inserted link nut (24), limits inserted link nut (24) simultaneously and is unlikely fully and withdraws from.When micromotor (22) was switched on 2 seconds and shuts electric current, course of action was the same, and direction is opposite.

Duplex electronic cryptosecurity case described in the utility model in sum has following advantage: code keypad is hidden, not fragile and destruction; Unblank to be the compound safety that increased; Motor-driven is unblanked brisk nimble; Many power works mode makes its compliance stronger.

Fig. 1 is the utility model structure principle chart.(1) is casing among the figure, bilayer; (2) be active clapboard; (3) be set bolt; (4) be from opening door; (5) be spring door bolt; (6) be the escape button; (7) be electric lock; (8) be drawer type key box; (9) be key box lock; (10) be keyboard; (11) be the charge power supply indicator lamp; (12) finish indicator lamp for charging; (13) be fuse base; (14) be attaching plug; (15) be box body, battery, charging equipment and cryptochannel and warning circuit are housed in it.

Fig. 2 is the structure principle chart of electric lock in the strongbox described in the utility model (7).(21) are the lock body shell among the figure; (22) be micromachine; (23) be drive screw; (24) be the inserted link nut; (25) be locking bar; (26) be preceding stopping bar; (27) be foot piece; (28) be the card frame; (29) be the back stopping bar.

Embodiment:

The TWH903D type product that the electronic cipher keyboard adopts Guangzhou Da Hua Electronics Factory to produce, its valid password combination is up to 10 ¹²Group, every group of 1-12 bit code is optional, because the password array is closed greatly, can't decode in therefore using, thereby improve safety.When this keyboard also has three input error sign indicating numbers in addition, report to the police automatically and the automatic keypad function that blocks.When unblanking, export at every turn 2 second control signal, micromachine (22) adopts the bigger slow speed motor of moment, a kind of available model is WJ1-180.During operate as normal, use interior the battery of box body (15), can use alternating current when the battery electricity uses up also, simultaneously also to charge in batteries, and charge power supply indicator lamp (11) is bright during with alternating current, and when charging finished, charging, it was bright to finish indicator lamp (12).

When strongbox is produced, its drawer type code keypad can be placed any position of strongbox, as: top, side, horizontal, vertically-arranged or the like; Set bolt (3) also can be placed on top, the back side, both sides, bottom surface etc.; Spring door bolt (5) can be arranged on the casing doorframe, or on the door.
