The specific embodiment
Below in conjunction with accompanying drawing the present invention is done further explanation.
Structural representation of the present invention is shown in accompanying drawing 4, and whole safety door lock device is divided into like the lower part:
First is main frame and card reader: it is used for rack and pinion drive mechanism is controlled (not shown);
Second portion is a rack and pinion drive mechanism: it is used for the inserted link action of runner is controlled, and concrete structure is shown in accompanying drawing 1;
Third part is a runner mechanism: it inserted link on the runner can inserted and withdraw from the jack of door makes Men Guan and open, and concrete structure is shown in accompanying drawing 2;
The 4th part is a guiding mechanism, and concrete structure is shown in accompanying drawing 3.
Rack and pinion drive mechanism mainly comprises: lock core 1, movable block 2, the first touch-switch fixed block 4, first touch-switch 3 (the said first touch-switch fixed block 4, first touch-switch 3 belong to guiding mechanism), latch 5, limited block 16, installing plate 17,12V small machine fixed mount 18, upper cover of lock 19, M3 screw 20, M5 screw 21, tooth bar 22, lock lower cover 23,12V small machine 24, gear 25, sliding support cover 26.
The rack and pinion drive mechanism compound mode is: gear 25 usefulness screws are fastened on 24 of the 12V small machines, and 12V small machine 24 tightens together through M3 screw and 12V small machine fixed mount 18, and then is fastened on the upper cover of lock 19 through M3 screw 20; Sliding support cover 26 is enclosed within on the pillar of locking lower cover 23 (it play the guiding role); The hole of one end of movable block 2 through installing plate 17 is affixed with M5 screw 21 and limited block 16, and the other end is enclosed within on the pillar of lock lower cover 23 and overlaps 26 end faces with sliding support and contact through sliding tray, and it is fastening and mesh with gear 25 that tooth bar 22 passes through screw and movable block 2; The first touch-switch fixed block 4 is affixed through screw and upper cover of lock 19, and first touch-switch 3 is locked on the first touch-switch fixed block 4 again; Upper cover of lock 19 is fastening through M3 screw 20 with lock lower cover 23; Installing plate 17 when mounted with door lock together, concrete mode is fixedly mounted on the door-plate for adopting fixed block 32, installing plate 17 is being fixed together through screw and fixed block 32, shown in accompanying drawing 6.
The effect of rack and pinion drive mechanism is to make rectilinear motion back and forth through the rotating band carry-over bar 22 of gear 25, makes latch 5 insert and withdraw from the groove of runner mechanism, thereby the rotation of runner 8 realizes that door can close and open in the restriction.
Runner mechanism mainly comprises: interior runner 8, outer hand wheel 27, first inserted link 9, second inserted link 10, the 3rd inserted link 11, locating piece 12.
Above-mentioned runner mechanism compound mode is: on the runner 8, outer hand wheel 27 linked to each other with interior runner 8 through connecting shaft in three inserted links were fastened on screw.
The effect of runner mechanism is: three inserted links in when outer hand wheel 27 clockwise rotates, driving on the runner 8 leave the jack in the doorframe, and this moment, door can be opened; Three inserted links in when outer hand wheel 27 rotates counterclockwise, driving on the runner 8 insert in the jack in the doorframe, and this moment, door can not be opened, and the positioning action of runner 8 in locating piece 12 plays is shown in accompanying drawing 5.
Guiding mechanism mainly comprises: second touch-switch 6, the second touch-switch fixed block 7, the 3rd touch-switch 13, the 3rd touch-switch fixed block 14, guide pad 15, and be installed in first touch-switch 3 and the first touch-switch fixed block 4 on the rack and pinion drive mechanism.
Above-mentioned guiding mechanism compound mode is: guide pad 15 is locked on the door; The second touch-switch fixed block 7, the 3rd touch-switch fixed block 14 are locked in respectively on the guide pad 15, and second touch-switch 6, the 3rd touch-switch 13 are locked in respectively on the second touch-switch fixed block 7, the 3rd touch-switch fixed block 14.
The effect of guiding mechanism is: the latch in the rack and pinion drive mechanism 5 is play the guiding role; Simultaneously when interior runner 8 and the 3rd touch-switch 13 are collided; The signal that produces passes to main frame moves downward rack and pinion drive mechanism limited block 16, stop motion when colliding with the limited block 16 and second touch-switch 6, and latch 5 inserts in the groove of interior runner 8; Runner 8 can not rotate in this moment; First inserted link 9, second inserted link 10, the 3rd inserted link 11 insert respectively under the guide effect of guide pad 28 in the corresponding hole of doorframe, and door is locked and can not be opened, and door-plate 31 phase door frame 30 can not 29 be rotated around the shaft.
The operation of opening the door:
Swipe the card; The signal that card reader produces uploads to main frame; Main frame is given an order and is made 12V small machine 18 drive affixed with it gear 25 to rotate counterclockwise, thereby makes the tooth bar 22 that is fixed on the movable block 2 with its engagement move upward, and drives also moving linearly upwards of movable block 2, limited block 16, latch 5; The signal that when limited block 16 and first touch-switch 3 are collided, produces passes to main frame; The control program of main frame makes 18 stop motions of 12V small machine, this moment can through rotate outer hand wheel 27 rotate in runner 8, first inserted link 9 affixed with interior runner 8, second inserted link 10, the 3rd inserted link 11 are left respectively in the corresponding doorframe jack; Can open door this moment, and the indicator lamp that is connected on second touch-switch 6 can be bright;
When after swiping the card, not rotating outer hand wheel 27, in the groove of runner 8, door was not opened, and make door open and need swipe the card again in 12V small machine 18 meeting driven gear rackwork moving handle latches 5 inserted again in the time of host setting.
The operation of locking a door:
Rotate outer hand wheel 27 drive in runner 8 turn to when colliding with locating piece 12; Be inserted in the corresponding hole of doorframe with first inserted link 9 of interior runner 8 Joints, second inserted link 10, the 3rd inserted link 11, the 3rd touch-switch 13 shell fragments also signal of compacted generation pass to main frame, and the instruction that main frame sends clockwise rotates 12V small machine 18 driven gears; After the time that mainframe program is set, move downward in the groove of runner 8 in the insertion with tooth bar 22, movable block 2, limited block 16, the latch 5 of its engagement; When limited block 16 and second touch-switch 6 were collided, the signal of the compacted generation of shell fragment of second touch-switch 6 passed to main frame, and the instruction that main frame sends stops operating 12V small machine 18; In the groove of the interior runner 8 of latch 5 insertions this moment; Door is locked, and at this moment indicator lamp does not work on second touch-switch 6, can relievedly leave.
Operation when main frame does not have electricity or is out of order:
Insert key drive lock core 1 rotation in the lock core 1 with key, movable block 2 is moved up or down, drive affixed with it tooth bar 22 and move, thereby make latch 5 leave or insert in the groove of interior runner 8, rotate outer hand wheel 27 and reach the purpose of opening the door and locking a door.
Characteristics of the present invention are: (1), compact conformation are simple, easy for installation; (2) the anti-theft effect performance is good.
