Description

The multi-function anti-theft alarm lock

The utility model relates to a kind of multi-function anti-theft alarm lock.

The door lock that sell on the home market at present, uses has common lock and anti-theft alarm lock, though these locks have certain theftproof performance, and function singleness, result of use is undesirable.

It is a kind of simple in structure, easy to use that the purpose of this utility model is to provide, and collection burglar alarm, door lock illumination and doorbell function are the multi-function anti-theft alarm lock of one.

The technical solution of the utility model is as follows: it is to be made of common spring lock, alarm, door bell device, lighting device, corresponding electronic circuit and power unit; Alarm is provided with two contacts, one is the false locking alarm contact, it is installed in the top of one of them pellet shot from a slingshot of spring lock, another is the Pickproof alarm contact, this contact is installed in the big dead bolt, be provided with insulator between Pickproof alarm contact and big dead bolt, the position corresponding to the Pickproof alarm contact in small shell is provided with navigation button; Be provided with bell button and illuminating lamp button on the panel of lock, be provided with 2～3 illuminating lamps at the edge of lockhole, electronic circuit and power-supply battery are installed in the lock body.

The utlity model has picking lock, door alarm and wrong spoon warning function, the automatic illumination functions of unblanking at doorbell function and night can be applicable to various iron gates, door, and proof box etc., simple in structure, easy to use safe and reliable.

In order to make the utility model structure clear more complete, below in conjunction with accompanying drawing, the utility model is described in further detail.

Fig. 1 is the structural representation of the utility model locking face.

Fig. 2 is the side cut-away view of the utility model lock.

Fig. 3 is the inner structure synoptic diagram of the utility model lock body.

Fig. 4 is the side structure synoptic diagram of the utility model lock body.

Fig. 5 is the cut-away view of the little lock housing of the utility model.

Fig. 6 is a schematic circuit of the present utility model.

Shown in Fig. 1～3, the utility model is to offer two macropores on the panel 1 of common spring lock, bell button 2 and illuminating lamp button 3 are installed in respectively in these two holes, on panel 1, be positioned at the periphery of tapered end 4, have three apertures, three illuminating lamps 5 are installed in the aperture, the false locking alarm contact 6 of alarm is positioned at the top of one of them pellet shot from a slingshot 7 of spring lock, the Pickproof alarm contact 8 of alarm is installed in the big dead bolt 9 of common spring lock, between Pickproof alarm contact 8 and big dead bolt 9, be provided with insulator 10, at small shell 11 internal fixation the identical navigation button 12 of cross sectional shape size and Pickproof alarm contact 8 is installed, navigation button 12 adopts conducting metal to make, in its cavity spring is installed, makes door lock under lock-out state, the Pickproof alarm contact 8 in the big dead bolt 9 can closely contact with navigation button 12.Battery chamber 13 is set above lock body, and loudspeaker 14 and electronic circuit board 15 are installed in the lock body shell, and their concrete installation sites can be decided according to the space according to the concrete structure and the size of lock.

As Fig. 6, the course of work of the alert lock of multifunctional burglary-resistant of the present utility model is as follows:

1. door bell device: be made up of bell button 2 and doorbell circuit, press bell button 2, connect the doorbell circuit, " ding-dong " or " music " sound that just sounds in the lock is realized the doorbell function.

2. lighting device: form by illuminating lamp button 3 and lamp wiring.Press illuminating lamp button 3, connect lighting circuit, illuminating lamp 5 is bright, is clocked by master control board lamp control circuit pack, turns off the light automatically after 30 seconds, illuminating lamp 5 is a photoelectric tube, lamp wiring in the control master control board is not lighted illuminating lamp 5 by day when daylight, and just play a role in lighting night, thereby reduce the loss of power supply, prolong battery serviceable life.

3. the wrong spoon of alarm: a. is reported to the police: when using the non-matching key, when key inserts lockhole, key jack-up pellet shot from a slingshot 7, make contact 5 closures, circuit is connected, and the memory section circuit carries out memory storage in the via line master control borad, when exceeding the scope that sets, promptly trigger alarm circuit, send chimes of doom.B. Pickproof alarm: originally be locked in the big dead bolt 9, be provided with Pickproof alarm contact 8, be locked under the normal locked state, 9 contact normally with 8, when lock or door are prized, produces relative displacement situation, then make normal contact condition produce change, thereby make line short circuit, alarm circuit sends chimes of doom in the shake-up master control board circuit.Above time of fire alarming can set up on their own.
