Description

Electronic coding alarm lock

The utility model relates to a kind of electronic code lock that is used for security door, safety cabinet and automotive door etc.

At present, various mechanical locks do not possess warning function, and electronic password lock, its complex structure, cost height, poor reliability is made the maintenance difficulty, so be unsuitable for generally applying.

The purpose of this utility model provides a kind of electronic code alarming lock, makes it safe and reliable, and cost is low, and is easy to utilize.

Have a groove on the dead bolt of described electronic code alarming lock with various three safety locks of original machinery or various theftproof locks, output termination one electromagnet by electronic control circuit, electromagnetic actuation or discharge a spring leaf, spring leaf is connected with locking plate, by spring leaf by electromagnetic actuation or discharge the stop door, make the dead or release dead bolt of stop badge, make electronic alarm lock realize coding and warning function.

The control circuit of described electronic code alarming lock has loader (1), and loader is made up of eight, ten or 12 stacked switches; Have encoder (2), encoder is by eight row's triplex rows, and ten row's four lines or 12 row five-element stacked switches are formed.Can form the eight-digit number word by encoder and get three, the tens word is got four or ten binary digits and is got five figure coding.The electronics sign indicating number is given by encoder and putting, and can change at any time.Cooperate an electron key again, if electron key with preset three bit digital, the electronics sign indicating number of 4-digit number or five digit number matches, and can start lock and open, otherwise controller will be reported to the police.Electronic password lock also has controller (3), eight-digit number, tens or 12 figure places in the encoder, can preset wherein three figure places, four figures or five-digit number, then will corresponding therewith three figure places, four figures or five figure three, four or five microswitch transition states with electron key.By encoder three, four or five positive pulse signals at the most many input nand gates of input nand gate L1 L1 output undersuing to next stage NAND gate L2, make it to export positive pulse, trigger controllable silicon S2 with this positive pulse, even circuit turn-on, the charged adhesive spring leaf of electromagnet, pull out locking plate, thereby open main lock.If with preset three, four or five-digit number not to sign indicating number, then the output signal of NAND gate L1 can not be given NAND gate L2, then S1 conducting makes loudspeaker (4) work by alert ring sheet, produces alarm sound.

The positive pole of controllable silicon S3 is connected in series with the positive pole of each element in the circuit, and control power supply power supply makes each element not charged under off position, prolongs each element application life.

Fig. 1 is an electronic code alarming lock overall structure schematic diagram.

Fig. 2 is electronic code alarming lock Electronic Control figure.

As shown in FIG., (1), loader; (2), encoder; (3), controller; (4), alarm; (5), main lock; (6), main dead bolt; (7), spring leaf, (8), locking plate; (9), electromagnet; (10), battery pack; (11), Machine guarding.

Fig. 1 has provided a kind of loader of being made up of eight stacked switches, can preset three figure places in the eight-digit number, realizes coding by the stacked switch of encoder, need hold a mechanical key and when unblanking electron key, when unblanking, earlier with electron key patchhole seat, main lock just can be opened.

Form by eight telescopic feeler levers during the electronics key, corresponding with eight microswitches of loader.Every feeler lever can independently stretch out or withdraw.(under its telescoping mechanism several being arranged).Make wherein one, two or three to stretch out when unblanking, insert in the loader and touch microswitch in the corresponding hole.If preset coding over against last in the encoder, can open main lock.Otherwise the master that do not open locks and reports to the police.Making which root feeler lever of electron key stretch out, is the coding that presets of the memory based encoder of owner, finishes when unblanking temporarily.After unblanking, just immediately feeler lever is resetted, do not stay coding.Even electron key is lost like this, do not worry to give away secrets yet.Choose the people of electron key, do not know to preset coding, also can't unblank, therefore safe and reliable.

Electronic control system is battery-powered, and when considering undertension or decompression, other is furnished with Machinery Control System, makes it securely unlocking, and during the battery pack normal power supply, can not use Machinery Control System, and duty will not cause that alert ring reports to the police.

The utility model can be used for family security door, safety cabinet, enterprises and institutions, Bank Insurance bin coded lock, also can be used for the usefulness of automotive door theft protection.If be loaded on the safety cabinet and unite use with mechanical code lock, then security performance is more reliable.If be loaded on the automotive door, an electron key need only be arranged, more convenient.
