Description
(1) technical field:
The utility model relates to a kind of electronic safe coded lock.
(2) background technology:
Electron controls technology has been widely used in the electronic safe of multiple employing electronic password lock having occurred in the strongbox field at present.The control circuit that these electronic password locks are formed by circuit such as the password input that constitutes with electronic component, password recognition, output drivings, three most compositions of tapered end parts of electric operator (dc motor, electromagnet) and machinery, all be equipped with battery in the strongbox mostly, minority then provides power supply by the external electric supply socket on the strongbox outer panels.Described control circuit board and electric operator are by battery in the case or external power supply power supply.When importing correct password, password recognition circuit is finished recognition and is provided signal and gives output driving circuit, drives tapered end by electric operator and finishes opening action.Easy to use, the good looking appearance of this class strongbox, more popular with users.But several situations in use take place through regular meeting in this class strongbox: 1. can forget Password unavoidably or lose IC-card; 2. the height of the quality of electronic component quality and manufacturer's technical level, electronic circuit and electric operator can break down; 3. battery short of electricity in the case.When the user runs into above-mentioned situation, just can't normally use strongbox.For this reason, when Chinese patent 01225399.5 provides a kind of electronic control mechanism cisco unity malfunction of electronic safe, also can open and lock the emergent lock of firm safe door easily.Its technical scheme is: the emergent lock of electronic safe comprises cross lock, movable jam plate, fixing guide pillar and be fixed on tapered end on the movable jam plate, it is characterized in that: described cross lock is equipped with the shift fork that can rotate with key away from an end of keyhole, and movable jam plate is provided with and can drives tapered end and come and go flexible the open the door baffle plate and the baffle plate of locking a door.After adopting such structure, when the electronic control mechanism cisco unity malfunction of electronic safe,, also can extract or deposit valuables easily, remove user's the matter of great urgency by enabling emergent lock.
Above-mentioned technology is attached to standard machinery with the base plate of electronic safe coded lock and locks, one group of standby mechanical key is opened mechanical lock and then drive coded lock tapered end is unpacked by increasing, its essence is that the electronic safe coded lock has become stealthy ornaments, as long as open emergent lock with key, thereby emergent lock is just opened strongbox by the base plate that drives the electronic safe coded lock.Be to have solved emergent problem outwardly, but greatly reduce the reliability of strongbox in fact.Electronic safe with respect to the meaning of standard machinery formula safe deposit box is, because mechanical key lock core technology easily is decrypted, and therefore must be with increase the difficulty that its machinery is decoded by the electronic cipher system.And in No. 01225399.5 patent, electronic safe can't remove this mechanical key, and electronic safe can only be a safe deposit box, and this has just seriously reduced the safety of strongbox, and its safety factor reduces greatly.
(3) summary of the invention:
The utility model aims to provide a kind of possess emergency system and safe electronic safe coded lock
Technical solution of the present utility model is as follows:
