Abstract
The utility model discloses an electronic code safe, whose safe body is made of thick steel plates. The inner side of the electronic code safe is provided with a drilling-proof protective layer, and a control circuit and a locking mechanism are installed on the drilling-proof protective layer. An electronic code lock time-limit circuit makes the open of the electronic code safe within the limiting time, and otherwise, the open and the automatic locking can not be realized. The electronic code safe has functions and advantages of the existing electronic code safe; also, the electronic code safe has the functions of smashing prevention, prying prevention, drilling prevention, hole drilling prevention, etc.; moreover, the electronic code safe is not easy to be moved, and the safety performance is reliable thereby.
Description
The utility model belongs to deposits the safe that currency, file, valuables are used.
Use the most general mechanical cipher safety cabinet at present, its casing adopts the steel sheet manufacturing of 1～2 millimeters thick, and the wall interface shape is spot welding.The employing that also has is interrupted riveted joint.Because of casing intensity is low,, thing in the case is taken out so utilize means such as pounding, prize, draw the hole easily casing to be destroyed.The mechanical code lock of safety cabinet all adopts and aligns the breach mode and unblank, and pries open weld bond from cabinet door wall interface the latch mechanism of mechanical code lock is exposed, and utilizes instrument or directly with hand breach is aligned the cabinet door to be opened and take out thing in the case; Can also on the lock navel of coded lock, hole and to lock pearl and destroy lock core can freely be rotated, on facing left the lock core horizontal center line at lateral edges place, check mark bores an open-work then, in thin excellent patchhole, rotary locking cylinder aligns breach the cabinet door is opened deposit in the taking-up case.Because the mechanical cipher safety cabinet exists above-mentioned defective, so safety performance has been subjected to very big influence, and it is dangerous to deposit valuables.Recently a kind of electronic password safe occurred, this safety cabinet adopts electronic password lock to replace mechanical code lock and has increased warning function.But casing still adopts the body structure of mechanical cipher safety cabinet, utilize traditional means of destruction still safety cabinet can be opened and take out deposit in the case, and owing to safety cabinet weight is removed more easily to implementing to open the cabinet means away from putting the cabinet place.So the safety performance of safety cabinet still can not be satisfactory.
The purpose of this utility model is improved existing electronic password safe, make it have the anti-hole of pounding, prize, bore, draw, and prevent that safety cabinet from being removed to function such as destroying away from putting the cabinet place, improve the confidentiality of electronic password safe and the reliability of safety performance.
The casing of electronic password safe (1) employing thickness is the steel plate manufacturing more than 5 millimeters, and tank wall face interface shape is continuously logical weldering.The inboard dress of cabinet door adds the anti-drilling topping of alloy steel (2) that hardness is higher than drill bit hardness, by locking bolt (4), shift fork (5), have the give up the throne latch mechanism that lock collar (6), pull bar (7), the electromagnet (8) in duct constitute and the main control box (3) that control circuit is housed of locking bolt and install, be fixed on the anti-drilling topping.In order to guarantee that casing has enough resistances of failure, the steel plate thickness of making casing is preferably 8～10 millimeters.
In order further to improve the confidentiality and the safety of electronic password safe, electronic password lock has key (11) in limited time, adopts five unlatchings of four codings.Control circuit by delay switching circuit, decipher judging circuit, the control circuit of unblanking, warning start-up circuit, AC and DC is changed automatic charger automatically and is formed.At first press in limited time key when unblanking and delay switching circuit is connected produce in limited time voltage prescribe a time limit, press unlock key (12) then, the pulse signal of unblanking is differentiated through the decoding judging circuit, the control circuit connection work electronic password lock unlatching of unblanking when meeting unlocking cipher.Uncaging time surpasses limiting time, electronic password lock automatic blocking.When unblanking only by unlock key not according to key in limited time or out of order, electronic password lock can not reported to the police by the opening safety cabinet yet.Unblank to encode digital identical with unlocking cipher, number sequence is deciphered judging circuit output signal warning start-up circuit connection work not simultaneously, and warning device sends warning, press unlocking cipher arbitrary unlock key in addition, signal is directly imported the warning start-up circuit connects the warning start-up circuit.Warning device promptly gives the alarm.Safety cabinet has only again when reporting to the police presses positive stop key and unlock key according to program of unblanking and unlocking cipher, and decoding judging circuit output signal makes the control circuit connection work of unblanking, and warning start-up circuit breaking alarming just can stop.
In order to make safety cabinet have good confidentiality, the shop front place dress that prescribe a time limit key and unlock key are installed at electronic password safe cabinet door adds the shadow shield (13) that has key hole, the cabinet door handle is designed to Key structure and can carries at any time, must utilize key handle could open the cabinet door when opening cabinet.
Use for the convenience of the users, safety cabinet be equipped with the convenient lock of machinery (15) for the user not when putting the cabinet place at any time the open and close safety cabinet use, safety cabinet has indicator lamp (14), light during the electronic password lock opening, extinguish during locking states, prevent that the user from forgetting the locking safety cabinet when putting the cabinet place.
The electronic password safe that the utility model provides not only has the function and the advantage of existing electronic password safe, and has and anti-pound, prize, bore, draw the hole and function and advantage such as be difficult for moving, so strong security, safety performance are reliable.
Accompanying drawing is an embodiment of the present utility model, is wherein a kind of form of structure of the present utility model.In addition can also be designed to the horizontal type structure, locking bolt can be made into forms such as two-sided bolt, four sides bolt, and dress adds temperature-sensitive element can increase the temperature alarm function, prevents to adopt gas, ARC CUTTING that safety cabinet is destroyed.
