The specific embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.
Embodiment 1:
Referring to Fig. 1, Fig. 3, present embodiment is made of Machinery Ministry and control circuit.Machinery Ministry is by micromachine 1, stopper element 2 and be fixed in lock core 7 one end swivel plates 3 and constitute.Swivel plate 3 is provided with draw-in groove 4, and stopper element 2 is by driving member control, and driving member comprises worm screw 8 and spring wire 5, spring wire 5 one ends are fixed on the stopper element 2, the middle part is clipped in a end along worm screw 8, and the other end inserts on the fixed head 6 in the perforate, and worm screw 8 is arranged on 1 in the motor.Control circuit is made of single-chip microcomputer IC1, triode Q1, Q2, Q3, Q4, Q5, capacitor C 1, C2, bridge-type motor-drive circuit IC2, diode D1, resistance R 1-R8; Single-chip microcomputer IC1 control signal output termination triode Q1 base stage, triode Q1 colelctor electrode meets power supply+VC, emitter stage serial connection diode D1 connects triode Q3 colelctor electrode, triode Q4 emitter stage, resistance R 1, R2 series arm one termination triode Q1 emitter stage, other end ground connection, resistance R 1, R2 series arm intermediate point connect triode Q2 base stage, and resistance R 3 cross-over connections are in resistance R 3 base stages, inter-collector, and capacitor C 1 cross-over connection is between the colelctor electrode and ground of triode Q3; Connect triode Q5 colelctor electrode after the triode Q4 base stage serial connection capacitor C 2, resistance R 5, R6, R7, R8 are respectively triode Q4 collecting electrodes, base stage, triode Q5 emitter stage, base resistance, and resistance R 6, R7, R8 one end all link to each other with triode Q4 emitter stage, resistance R 5 one end ground connection, triode Q5 grounded emitter.
The operating principle of present embodiment is: motor counter-rotating when micromachine powers up, and worm screw is rotated spring wire, and spring steel wire drives in the draw-in groove of stopper element insertion swivel plate, and key can not be rotated.
Embodiment 2:
Referring to Fig. 2,3, present embodiment is made of Machinery Ministry and control circuit, and Machinery Ministry is made of micromachine 1, stopper element 2 and the swivel plate 3 that is fixed in lock core 7 one ends, and pole of rotation 3 is provided with draw-in groove 4, and stopper element 2 is arranged on 1 in the motor.Control circuit is identical with embodiment's 1.
