Abstract

The utility model discloses a double-control multifunctional door lock. The double-control multifunctional door lock is composed of the parts of a lock core, a lock core sleeve, a circuit depot, etc. A photoacoustic double-control circuit which comprising an input pole, a middle adjusting pole, and an output pole is arranged inside the circuit depot. The input pole is composed of the main components of a microphone, a triode transistor, etc. The middle adjusting pole is composed of the main components of a potentiometer, a music integrated sheet, etc. The output pole is composed of a microphone, a triode transistor, a photoresistor, an LED, a lock switch, etc. The double-control multifunctional door lock integrates the functions of a door lock, a door bell, and an indicating lamp into an integral body. The double-control multifunctional door lock has compact structure and convenient use. Compared with the past marble door lock, manual control and other requirements are not needed to be additionally arranged. The double-control multifunctional door lock has low power consumption, long service life, and high commerciality.

Description

Dsouble controlled multifunction door lock

The utility model is a kind of improved door lock.

Present pin tumbler lock effect used in everyday is single.Along with the development of house blocking,, need install doorbell on the cell gate for ease of the visitor.In addition, do not have the illumination device outdoors mostly, make troubles to unblanking night.

The purpose of this utility model provides a kind of multi-function door lock of photoacoustic dual-controlled, integrates door lock, doorbell, indicator lamp.

The utility model is a kind of lock housing 1 that comprises, circuit storehouse 2, lock core 8, lock core cover 9, movable lug 10, the door lock of pair tongue 11.Its technical essential is that the photoacoustic dual-controlled circuit is set in the circuit storehouse, and this circuit comprises input stage, middle level, output stage three parts adjusted.Input stage is made of critical pieces such as microphone 7, transistor T1; The middle level of adjusting is made of critical pieces such as potentiometer 4, music integrated chip IC; Output stage is made of loudspeaker 3, transistor T2, T3, T4, light resistor 6 and critical pieces such as light emitting diode 5, lock-switch K.The signal output part of the microphone 7 of input stage connects the base stage of transistor T1, the trigger end L that the colelctor electrode of transistor T1 is adjusted the music integrated chip IC of level through electric capacity and centre links to each other, the output N of music integrated chip IC is connected to the transistor T2 of output stage and the base stage of T3, the emitter stage of transistor T3 connects the base stage of the transistor T4 that its colelctor electrode links to each other with light emitting diode 5, is connected to light resistor 6 between transistor T3 and lock-switch K.Light emitting diode 5 that this is novel and light resistor 6 all are placed in lock core cover external surface.

The utility model collection door lock, doorbell, indicator lamp act on one, and compact conformation is easy to use, and pin tumbler lock need not to set up manual control and other requirement relatively in the past, and low in energy consumption, the life-span is long, commercial sexual valence height.

The explanation of accompanying drawing drawing:

Fig. 1 is the utility model installation drawing.1-lock housing among the figure, 2-circuit storehouse, 3-loudspeaker, 4-potentiometer, 5-light emitting diode.

Fig. 2 is the outdoor elevation of door lock.6-light resistor among the figure, 7-microphone, 8-lock core, 9-lock core cover.

Fig. 3 is the indoor elevation of door lock.10-movable lug among the figure, 11-pays tongue.

Fig. 4 is the photoacoustic dual-controlled circuit diagram.R1 among the figure～R4-resistance, T1～T4-transistor, C1～C2-electric capacity, IC-music integrated chip, K-lock-switch, EC-power supply.

Below to this novel further narration: when kowtowing when hitting door, microphone in the input stage 7 is converted to voltage signal with vibration, is amplified the music integrated chip IC that adjusts level again in the middle of reaching after capacitor C 1 coupling by transistor T1.Potentiometer 4 can provide dead level to adjust the trigger sensitivity of music integrated chip IC.When indoor man-hour arranged, in the main tongue 10 returned lock bodies, only have the tongue 11 of paying to stretch out, then lock-switch K key is put a end, and transistor T2 just amplifies the music electrical signal of music integrated chip IC output, and is spread out of by loudspeaker 3.When opening door lock also is like this.When indoor unmanned, when a promptly main tongue 10 and a pair tongue 11 all stretched out, lock-switch K key was put the b end, and transistor T3, T4 accept the time delayed signal of music integrated chip IC output, and no musical sound sends.When visibility was low outdoors, as long as the tapping door-plate, light resistor 6 just started transistor T3, T4 work, and light emitting diode 5 just can throw light on, and capacitor C 2 and resistance R 4 work to make the illumination time-delay.As want to judge whether to have locked door, and only need block the light resistor 6 on the lock core, diode 5 as luminous promptly shows to shut to finish.As long as microphone is not experienced the vibration of door-plate, entire circuit just is in cut-off state (static state) all the time.

Component is selected: T1～T4 3DG6, and 7 usefulness CZN-15E type microphones, IC adopts the KD9300 music integrated chip, and 3 select 8 Ω permanent magnetic field loudspeakers for use, and 6 use light resistor MC15S, and power supply adopts No. 5 batteries of two-section.Its quiescent current of the door lock that is assembled into is not more than 100 μ A, and dynamic current is not more than 150mA, and music tone ringer continues 5 seconds, illumination time-delay 60 seconds.
