CN2393968Y - Door lock with light and sound alarm - Google Patents

Abstract

The utility model relates to a door lock with a light and a sound alarms. The utility model is provided with a lock core assembly, and a lock core tongue, and is also provided with a sound and light control template, a key discrimination alarm, an LED, etc. A 3-6 V power supply is connected between all elements by a conducting wire, two button switches control the on-off of a circuit, which realizes the illumination of the LED and the sounding of a buzzer of the alarm. The utility model has the advantages of simple burglarproof alarm function, and provides the convenience of illumination for searching a key hole under a dark condition.

Description

The acoustooptic display alarm door lock

The utility model relates to a kind of lock, is a kind of alarm door lock that has acousto-optic to show.

Existing common door lock does not generally all have warning device, and perhaps the installation cost height is not suitable for family and office and uses.Unblank in dark place, be difficult for seeking keyhole, and also be common worry.

The purpose of this utility model is that a kind of acoustooptic display alarm door lock that the simple alarming device is arranged and the keyhole place is had illuminating effect will be provided.

The utility model is achieved in that in the door lock lockset except that lock core assembly, lock core tongue are arranged, to also have acousto-optic control module, key to differentiate alarm, light emitting diode etc.Two press buttones are arranged, and one places the key hole inner end, and another connects the hairpin of dialling on the lock core tongue.Light resistor and Electret condenser microphone are housed on the acousto-optic control module.Buzzer and accessory power outlet are housed on alarm.Be unified into galvanic circle with lead by plug connector with power supply between each device.

The utlity model has easy anti-theft alarm function, and the illumination convenience of searching keyhole is provided for the dark place.

Below in conjunction with accompanying drawing in detail the utility model is described in detail.

Fig. 1 is the utility model structure principle chart.

With reference to accompanying drawing, be installed in the lock core assembly 1 on the door, there is a duck eye adorning light emitting diode 17 in key hole 2 outer ends, be the keyhole illumination.Key hole 2 inner ends, inching button switch 15 is housed, constant close contact 3 of switch 15 and constant open contact 16 usefulness leads connect the positive pole of 3-6V power supply 9, another constant open contact 16 connects key by inching button switch 13 and differentiates alarm 7, alarm 7 another contacts connect power supply 9 negative pole harmony photocontrol modules 10, module 10 has two contacts to connect another constant close contact 3 with 17, one contacts of lead sending and receiving optical diode with lead in addition.The lock core assembly connects with lead between the lock body assembly, by plug connector 14 conductings.Light resistor 12 and Electret condenser microphone 11 are housed on acousto-optic control module 10, buzzer 6 and accessory power outlet 8 are housed on alarm 7.

Under the normal illumination condition, because the effect of light resistor 12 makes light emitting diode 17 not luminous, only when dark, Electret condenser microphone 11 is received voice signal, just makes light emitting diode 17 luminous.When the stranger attempted with other key runin doors, key entered in the jack 2, pushes press button 15, control module 10 outages, and alarm 7 energisings are then sent alarm signal by buzzer 6.If use accessory power outlet 8 and neighbours and the networking of relevant security authority, can report to the police many places.In the normal door process, key can very fast rotational lock core tongue 4, makes press button 13 deenergizations by dialling hairpin 5, allows alarm 7 not work.The alarm settings time, can adjust setting on demand.

Claims (2)

1, a kind of acoustooptic display alarm door lock, form by lock core assembly, lock core tongue etc., it is characterized in that: key hole (2) outer end in lock core assembly (1) has a duck eye adorning light emitting diode (17), and inching button switch (15) is being adorned in key hole (2) inner end; The hairpin (5) of dialling that is overlapping on the lock core tongue (4) is joining inching button switch (13); There are an acousto-optic control module (10) and a key to differentiate alarm (7), respectively there is contact to connect power supply (9) negative pole with lead, power supply (9) positive pole connects inching button switch (15), another constant open contact (16) of switch (15) is by switch (13) device taking alarm (7), another constant close contact (3) of switch (15) connects control module (10), and module (10) is also by lead sending and receiving optical diode (17); Light resistor (12) and Electret condenser microphone (11) are housed on acousto-optic control module (10), buzzer (6) is housed on alarm (7).
