Just can finish the whole operating process of power supply control with a optical key with a button, very easy to use, and have only legal optical key to open, the optical key of a certain sequence number is lost in system, after as long as the generated light key of same series number is obtained the authorization, original optical key cancels; As long as encryption key pair is not revealed, optical key can not duplicate.
In addition, because electric control door lock has varied, preferred implementation as the utility model electric control door lock, as Fig. 5, shown in Figure 6, the motor 1 that is connected with control circuit is arranged in lock body, motor 1 is connected with worm screw 2, worm screw 2 links with dual gear 3, the angle of spiral of described worm screw 2 is less than the equivalent friction angle of the field of conjugate action, dual gear 3 with revolve moving tooth wheel 4 and be meshing with each other, the described direction of rotation of moving tooth wheel 4 of revolving is for clockwise, 4, when revolving moving tooth wheel 4 and rotating, revolve shifting block 5 and push roof pressure respectively open and make the dead bolt 7 release lock buckle panels 12 that are positioned on the guide rod 6 at jacking block on the dead bolt 78 and pulling dead bolt boss 71, described jacking block 8 middle parts are movably arranged in the universal latch with fulcrum 82, and can rotate around fulcrum 82, be installed with the wind spring 81 that resets on the fulcrum 82, cross-under has reseting pressuring spring 61 on the described guide rod 6, is fixed with positioning rubber column 13 on the described dead bolt 7 and cuts spring 9 with the light that is used to touch the optoelectronic switch 15 on the wiring board 14.
When door is under the closing state, open this sect, at first will be by optical key, optical key sends a signal, the first signal of acceptance on the wiring board 14 is transferred to microprocessor then, is started by the motor 1 in microprocessor identification legal key and the control universal latch again, and motor 1 drives worm screw 2 and rotates, worm screw 2 changes its rotation direction and deceleration by the worm gear of dual gear 3 again, revolves moving tooth wheel 4 by the straight-tooth engagement of dual gear 3 at last; The direction of rotation of revolving moving tooth wheel 4 is for clockwise.When revolving 4 rotations of moving tooth wheel, the shifting block 5 that revolves that is positioned at above it is at first pushed the jacking block 8 of roof pressure on dead bolt 7 open, jacking block 8 rotates around fulcrum 82, thereby vertical direction away from dead bolt 7, and reverse reset wind spring 81 simultaneously, revolves moving tooth wheel 4 pulling dead bolt boss 71, dead bolt 7 slides to the right along guide rod 6, and compression reseting pressuring spring 61; In the process of sliding, be positioned at light on the dead bolt 7 and cut spring 9 and also be synchronized with the movement to the right, when light was cut spring 9 and touched the optoelectronic switch 15 of wiring boards 14, motor 1 stopped to move.At this moment, revolve shifting block 5 and do not leave dead bolt boss 71, because the angle of spiral of worm screw 2 is 5 ° 43 ' 38 "; less than the equivalent friction angle of the field of conjugate action, worm screw 2 has self-locking performance, does not circle round moving so revolve moving tooth wheel 4; thus decide to have lived dead bolt 7; at this moment dead bolt 7 is waited and has been left latch plate panel 12, and door can freely be opened, and the action of opening the door is finished.
With reference to Fig. 6, in order to prevent under unlocking condition, door is opened in blow and the slight vibrations of wind, and the utility model is equipped with positioning bead 10 in universal latch, and the protruding pearl on the described positioning bead 10 is pressed under the elastic force effect of deciding pearl stage clip 11 in the groove on the buckle panel 12, under unlocking condition, as long as slightly firmly door just can be opened, in this mechanism, positioning bead 10 and decide pearl stage clip 11 and played the effect of locating, can be door being pull-in on the doorframe tightly, thus a band is lived.At closing time, positioning bead 10 can be like a cork entered in the groove by the slope on the importing limit of buckle panel 12.This lock is applicable to turnover more frequently and on the gateway of often not locking, and turnover is without optical key control, if will leave really just on the usefulness light key lock, brings convenience to life.
In the time of need locking a door, at first to close door, positioning bead 10 is entered in the groove of buckle panel 12, at this moment click optical key again, the acceptance head of wiring board 14 receives signal, be transferred to microprocessor again, control motor 1 action through microprocessor identification with after handling by buffer circuit, motor 1 turn to when opening the door turn to identical, thereby the phenomenon of having avoided worm screw 2 transmissions counter-rotating to kill, motor 1 makes by identical transmission mechanism and revolves 4 rotations of moving tooth wheel, because turning to of motor 1 is constant, takes turns 4 rotation directions still for clockwise so revolve moving tooth.It revolves shifting block and has broken away from dead bolt boss 71 when revolving moving tooth wheel 4 and be rotated further, and at this time, dead bolt 7 to left movement, is cut spring 9 with the time and left optoelectronic switch 15 on the wiring board 14 under the effect of reseting pressuring spring 61, and motor 1 stops action.Dead bolt 7 is in the process of left movement, and when positioning rubber column 13 touched the inside edge of lock housing, dead bolt stretched out and finishes.At the same time, jacking block 8 snaps onto on the bayonet socket of dead bolt 7 under the twisting force of wind spring 81 that resets, and under artificial effect, dead bolt 7 can not be regained, thereby plays the effect of locking.
Mechanical part of the present utility model has in addition adopted worm and gear and gear transmission structure, the precision height of transmission, steadily, vibrations, impact and noise be all very little, and it uses motor as power source, replaced traditional armstrong's patent lock, and on lock body, do not have keyhole, avoided duplicating of artificial mechanical damage and key; In addition, it uses jacking block 8 to snap onto on the bayonet socket of dead bolt 7, and under artificial effect, dead bolt 7 can not be regained, and prevents artificial spade door thereby reach, and has improved its safety widely.
