In the accompanying drawing: 1-motor, 2-locking bolt, 3-dead bolt, 4-dead bolt driving chip, 5-lock housing, 6-drive link, 7-circuit board, 8-bearing pin, 9-gear 10-gear, 11-gear, 12-gear 13-key chain, 14-key body 15-circuit board, 16-battery, 17-coding circuit, 18-decoding circuit, 19-mu balanced circuit, the full-automatic charging circuit of 20-, 21-rectification circuit, 22-capacity voltage dropping circuit, 23-drive circuit.

Shown in Fig. 1,2,3,4,5.

At first lock is fixed on the door, power input is inserted on 220 volts AC powers, loads onto the silver-colored zinc button cells 16 of two joint SG3 in key body 14.During installation the M1 in the M1 in the coding circuit 17 end and the decoding circuit 18 held to draw and be connected on the lock housing 5.When unblanking, at first press the button AN1 on the key body 14, key chain 13 is contacted with outer lead on the lock housing 5.14 pin of coding circuit 17 over the ground, 17 pin of coding circuit 17 divide one group of serial code of output automatically four times, after decoding circuit 18 is received serial code, through inter-process, if when frequency is identical, positive pulse of 14 pin output of decoding circuit 18, by diode D2 shaping, trigger controllable silicon T1, after the controllable silicon T1 conducting, by the rotating of reversing switch K1 control motor 1, motor 1 drives dead bolt 3 by gear and realizes unblanking or locking.When reversing switch K1 is in a, b contact position contacting, motor 1 beginning rotation counterclockwise, gear 12 on motor 1 main shaft is by gear 11, and gear 10 driven gears 9 rotate, and bearing pin 8 is housed on the gear 9, when gear 9 rotates, bearing pin 8 is stirred dead bolt driving chip 4 and is moved right, and dead bolt 3 also moves right under the drive of dead bolt driving chip 4, at this moment door-lock opening, when dead bolt driving chip 4 moves right, make reversing switch K1 be converted to b, c contacting by drive link 6.Controllable silicon T1, motor 1 of short duration outage at this moment, during outage, controllable silicon T1 ends, and motor 1 stall stops after at this moment dead bolt 3 is opened, and bearing pin 8 goes to the right side, waits for next time driving.

During locking, key chain 13 contacts with outer lead on the lock housing 5, and changeover switch K1 is in b, c contacting, and motor 1 beginning clockwise direction rotation through reducing gear, drives bearing pin 8 from the right hand steering left side, drives dead bolt 3 simultaneously and is moved to the left, the door lock closure.After the locking, a of reversing switch K1, b be to contacting, the of short duration again outage of controllable silicon T1, and controllable silicon T1 ends, and dead bolt 3 just is in the state of locking.

Circuit of the present utility model is connected in 220 volts of alternating currents (50HZ), when the battery electric quantity in this lock is sufficient, and triode BG1 conducting, BG2 ends, and stops to be battery charge.If when battery electric quantity was not enough, triode BG1 ended, the BG2 conducting is battery E charging.Potentiometer W1 is connected to the two ends of battery E, and the moving plate P of potentiometer W1 is connected to the base stage of triode BG1, and its effect is that moving plate P is adjusted to: when battery E both end voltage during greater than rated voltage, trigger triode BG1 conducting stops charging; When battery E both end voltage during less than rated voltage, triode BG1 ends, by 220 volts of alternating currents through capacity voltage dropping circuit 22, rectification circuit 21, full-automatic charging circuit 20 is given battery E charging automatically.

The effect of voltage-stabiliser tube D1 in the mu balanced circuit 19 is when preventing that circuit voltage is too high, damages decoding circuit 18.

When the effect of the capacitor C 3 in the coding circuit 17 is the battery 16 that prevents to change in the key body 14, lose the internal memory coding.
