The present invention is further described below in conjunction with drawings and Examples.

Fig. 1 is a structural representation of the present invention;

Fig. 2 is the A-A sectional view of Fig. 1;

Fig. 3 is a dual gear structure broken away view of the present invention;

Fig. 4 is the structure broken away view of dual gear other direction of the present invention.

The specific embodiment

With reference to Fig. 1, Fig. 2, a kind of intelligent electric controlled lock, it comprises lock body 1, is provided with the motor 2 that is connected with control circuit in the lock body 1, be connected with worm screw 21 on the motor 2, worm screw 21 links with dual gear 4, and dual gear 4 is meshed with tooth bar 5, is fixed with dead bolt 6 on the tooth bar 5, also be provided with triangle tongue 7 on the described lock body 1, be provided with spring 9 between triangle tongue 7 and the lock body 1, described motor 2 is connected with touch switch 8, but described triangle tongue 7 is provided with the boss 71 of roof pressure touch switch 8.

This product is in order to control the shift motion of dead bolt 6, and described lock body 1 is provided with bearing pin 11, and the strip-type hole 51 of cross-under on bearing pin 11 is set on the described tooth bar 5.In addition, be extended with protruding axle 52 on the described tooth bar 5, described lock body 1 be provided with can with protruding axle 52 contacted left and right limit switches 31,32, left and right limit switch 31,32 is connected with motor 2, this design has effectively prevented strip-type hole 51 and the rigid collision that bearing pin 11 occurs, and adopts left and right limit switch 31,32 to control stopping of motor 2.

The operating principle of this product is: in the time of need locking a door, at first to close door, at this moment, doorframe is pressed into triangle tongue 7 in the lock body 1, compress spring 9 simultaneously, and the 71 roof pressure touch switchs 8 of the boss on the triangle tongue 7, make motor 2 rotate, motor 2 moves forward by worm screw 21 and dual gear 4 control tooth bars 5, after the protruding axle 52 on the tooth bar 5 touches right limit switch 32, to control motor 2 and stop operating, at this moment, the dead bolt 6 on the tooth bar 5 has inserted the effect that realization is locked a door automatically in the doorframe bayonet socket; When needs open the door, start and open switch, motor 2 begins counter-rotating, motor 2 moves backward by worm screw 21 and dual gear 4 control tooth bars 5, make dead bolt 6 be retracted in the lock body 1, the control that breaks away from the doorframe bayonet socket, when the protruding axle 52 on the tooth bar 5 touch sit limit switch 31 after, will control motor 2 and stop operating.When the door body was outwards pulled out, spring 9 was released triangle tongue 7 outside the lock body 1, and the boss 71 on the triangle tongue 7 breaks away from mutually with touch switch 8 simultaneously.

The present invention disposes two limit switches 31,32, cleverly the rotating of motor 2 is controlled, and makes that the switch control of electric control lock is convenient.In use, can preset the run duration of motor 2 earlier, and make proper extension, put in place to guarantee motor 2 motions, simultaneously, because the existence of limit switch 31,32 as long as motor 2 motions put in place, touches limit switch, motor 2 just quits work, so, just feasible more accurate to the control of motor 2, therefore more help using.

With reference to Fig. 3, Fig. 4, the dual gear 4 that this product uses is flexible energy storage type dual gear, it comprises the gear wheel 41 that is meshed with worm screw 21, described gear wheel 41 is provided with containing cavity 411, be provided with left and right mounting groove 412,413 in the containing cavity 411, the left and right two ends of left and right mounting groove 412,413 are respectively arranged with spring 43, be equipped with in the described containing cavity 411 and tooth bar 5 pinion in mesh 42, described pinion 42 is provided with and is plugged in the left and right mounting groove 412,413, and the convex tendon between left and right spring 43 421,422.

In the process of locking a door, when if dead bolt 6 runs into excessive resistance, tooth bar 5 will be controlled pinion 42 stop motions, motor 2 still is in rotary state, thereby rotatory force is delivered on the gear wheel 41, gear wheel 41 is rotated and compress spring 43, after the resistance of dead bolt 6 is removed, to control pinion 42 and by tooth bar 5 dead bolt 6 be inserted the doorframe bayonet socket fully under the pressure of spring 43, this design is provided with spring 43 with dual gear split design between it, after adopting spring 43 to prevent that dead bolt 6 from meeting obstructions, locking phenomenon appears in motor 2 rotating shafts, and the locking back produces deflection yoke when having avoided dead bolt 6 to meet obstructions simultaneously, improves security performance.

The mechanical part of this product has adopted worm gear, worm screw and gear, rack for transmission structure, the efficient height of transmission, precision height, 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, when dead bolt 6 inserted the doorframe bayonet socket, under artificial effect, dead bolt 7 can not be regained, and prevents artificial spade door thereby reach, and has improved its safety widely.
