Abstract
The utility model discloses an electrically controlled anti-theft door lock which is composed of a lock shell, a lock tongue, an electrically controlled lock core device and a drive circuit, wherein, the electrically controlled lock core comprises motors controlled by the drive circuit, a worm wheel, a worm, reduction gears, a rack bar and a gear; both ends of the worm are connected with the two motors via the reduction gears, and the worm is driven by the motors to rotate; the gear is fixed on a rotating shaft of the worm gear, the gear is arranged in a longitudinal notch on the rack bar driving the lock tongue, and the gear which is engaged with a tooth body on one side of the notch drives the rack bar to move in a reciprocating mode. The device can realize that the motors directly drive the lock tongue to work. The utility model has the advantages of simple structure, small volume, low cost, stable work, etc.
Description
Technical field
The utility model relates to a kind of safe-guard door lock device, particularly relates to a kind of automatically controlled safe-guard door lock device.
Background technology
Existing electric control door lock adopts electromagnetic drive mode mostly, and it utilizes the suction-combining force of magnetic, finishes the locking and the release work of opposite house tongue by driving a lock pin.Described traditional electric control door lock exists following shortcoming: at first, the dynamics of electromagnetism the suction-combining force is not enough, and the poor reliability of controlled motion parts work more can not be finished the direct task of driving the door tonguing, so be not electric auto-control door lock truly; Secondly,, just must use the large power, electrically magnetic device, therefore, when increasing power consumption, the problem of high fault rate also can occur in order to improve the reliability of work; The 3rd, the impact force of electromagnetism adhesive easily causes damage to moving component, influences the application life of device.
Summary of the invention
Problems such as novel anti-theft electric control door lock described in the utility model can solve control driving force deficiency that above-mentioned traditional electric control door lock exists, functional reliability is poor, power consumption is big, fault rate is high and application life is short.It can directly drive dead bolt and finish locking and return, realizes the electric control function of real meaning.
Novel anti-theft electric control door lock described in the utility model is made up of lock housing, dead bolt, electric control lock core apparatus and drive circuit; Described electric control lock core apparatus comprises: the drive motors that is connected with drive circuit, worm gear and worm screw, reduction gearing, rack and pinion; Described worm screw two ends are arranged on a pair of spring bearing, and its end face links with the output shaft of a pair of reduction gearing respectively, and described a pair of reduction gearing is respectively by the drive motors driven rotary of correspondence; Described worm gear and worm engaging, the gear of the interlock that on the axis of rotation of worm gear, is fixedly connected; This gear is placed in vertical notch of a tooth bar; Vertical notch one side of this tooth bar has the denticle with described gears engaged, and the vertical notch of described tooth bar another side is the plane; The vertical width of rebate of this tooth bar is to be placed in one gear, and its both sides coincide mutually and are advisable; The end of described tooth bar can link with one or more dead bolts, and under the drive of gear, realizes locking and the conversion that resets.
The utlity model has following effect:
1. can drive the flexible conversion of door tongue by motor-driven mode, realize the control function of unblanking and locking;
2. the electric control door lock that a kind of frame for movement is simple, volume is little and cost is low is provided;
3. type of drive can be diversified, cooperates different drive circuits, can finish unblanking of door lock or go up lock control with remote control, IC-card or other control mode;
4. adopt the transmission of power between a pair of reduction gearing realization drive motors and the worm screw, can overcome bi-motor and directly drive the worm screw two ends, the rotation problem of unstable of bringing can improve efficiency of motor and increase the service life.

The specific embodiment
The concrete structure of automatically controlled lock core described in the utility model can be referring to Fig. 1,2,3, as can be seen from the figure, worm screw 4 is fixed on the pair of bearings 3, and its two ends link by the drive motors 1,6 of reduction gearing 2,5 and both sides respectively, and is driven rotation by the bilateral drive motors.Connect with the axle 14 of the worm gear 7 of described worm screw 4 engagements, and the gear 8 of rotation is placed in vertical notch 11 of opening on the tooth bar 9 synchronously, the external diameter of gear 8 is suitable with the width of this vertical notch 11, make its denticle and vertically denticle 10 engagements of notch 11 1 sides, when gear 8 positive and negative rotations, described tooth bar moves toward complex line thereupon.Described motor 1,6, bearing 3, axle 14 all are fixed on the housing 13 of automatically controlled lock core, and described tooth bar 9 two ends pass the front and back end of housing 13.The tooth bar 9 of described housing 13 both sides passes the hole and can be moving back and forth of tooth bar 9 the positioning and guiding slideway is provided.Reciprocating stroke extreme position at tooth bar 9 can be provided with spacing gauge tap, and after it moved into place, (this device is not shown among the figure) quit work with the control drive motors.
An integrally-built embodiment of the present utility model can be referring to Fig. 4,5, as can be seen from the figure, described electronic lock core is provided with an allocation tongue device 18 by in the screw lock housing 16 at lock housing 16 places in dead bolt 12 left sides, lock housing 16 places on right side are provided with one from dead bolt device 14.In the present embodiment, also comprise the side chain tongue 15,17 of locking both sides.The medial extremity of described two side chain tongues 15,17 can have an oblique chute, can be equipped with in this chute one with dead bolt 12 synchronization-moving travellers, by cooperating of not shown chute and traveller, side chain tongue 15,17 and dead bolt 12 are moved back and forth synchronously.
The automatically controlled lock core that utilizes Fig. 1,2,3 to provide can drive various forms of dead bolts, finishes the action of unblanking and locking of electric control door lock.The control circuit of described drive motors can be that wireless encoding remote control circuit, IC-card recognition control circuit or other have the circuit of identification control function.
