Description

Electronic theft-deterrent door

The utility model provides a kind of electronic anti-theft door, comprises doorframe, integral door body, and door locking device, belongs to building class window technology field.

At present, the security door kind is more, as doors locking type security door, steel wood combined anti-theft door etc.Its anti-theft measure mostly is a body reinforcing, multiple spot is established lock or composite lock is set, and stresses to consider antitheft requirement from mechanical aspects.Because warnings of can not ringing of these security doors can not be implemented appropriate strike to the thief, and the thief is not produced deterrent effect, therefore, the use of this class security door, and fail effectively to reduce the generation of burglar.

At the above-mentioned deficiency of existing security door anti-stealing technology, the purpose of this utility model provide a kind of the thief implemented to force open the door press lock as the time, promptly report to the police automatically, and to stealing the electronic anti-theft door that the person carries out the appropriateness electric shock.

Above-mentioned purpose of the present utility model, realize by following technical measures:

On the door body, be provided with and comprise by resistance the charging circuit that electric capacity constituted; By the prime triode that joins by Zener diode and charging circuit, the pressure drop of preceding stage transistor collector is that the back one-level of bias voltage promotes the amplifying circuit that amplifying triode is formed; Be connected to amplification circuit output end by the voice sheet, the warning circuit of ringing that voice amplifier integrated block and loudspeaker are formed; The electronics of the common formation of electric-shocking circuit institute that is connected to mechanical oscillation, the high-tension transformer of the back level transistor emitter that promote to amplify and inter-collector is rung, electric shock device.

The high-voltage output end of this device and join with the whole door leaf of door body insulation;

Between back level triode base one emitter-base bandgap grading that promotes to amplify normal open switch is set, this switch is arranged on the integral door limit;

On the door body, also be provided with one and be terminated at Zener diode, the charge discharging resisting button of other end ground connection;

Charging circuit joins by press button in the door and dc source.

The electronic anti-theft door course of work is as follows: when locking a door, at first by button switch in the Xiamen, make charging circuit connect power supply.Charging circuit work, when charging voltage reaches set-point, Zener diode conducting (snowslide conducting).The prime triode of amplifying circuit is followed conducting, produces pressure drop on the colelctor electrode, and the promotion amplifying triode of a bias voltage to the back one-level is provided.Because the normal open switch of being located at a limit is closed because of door body and doorframe extruding, make to promote that the amplifying triode base---emitter-base bandgap grading joins, and this pipe is not worked.In case door is pried open, a door limit normal open switch recovers open mode, promotes amplifying triode because the bias voltage that the prime triode provides and conducting (work), voice sheet, amplifier integrated block work, the loudspeaker warning of sounding.Be connected to mechanical oscillation and high-tension transformer work in collection one emitter base diode circuit that promotes triode, produce high pressure,, implement electric shock the stealer dispensing high-tension current of contact door body.When owner opens the door, then can at first press the charge discharging resisting switch of being located on the door, also do not finish charging process because of charging circuit when opening the door, not conducting of Zener diode can not implemented electric shock to owner, can not produce the warning of ringing yet.The charge discharging resisting switch should hidden setting.

The electronic anti-theft door that the utility model provides, possessing rings reports to the police and the two kinds of functions that shock by electricity, and can contain effectively that the burglar commits a crime.

Accompanying drawing is to ring in the electronic anti-theft door to report to the police and the electrical schematic diagram of electric shock device most preferred embodiment.

Resistance R ₁, capacitor C ₂, capacitor C ₃The composing type charging circuit.The 6V dc source is through button switch K ₁With charging resistor R ₁Join.The prime triode BG of amplifying circuit ₁Base stage by Zener diode D ₂Join with charging circuit, colelctor electrode is established divider resistance R ₃, R ₄, promote triode BG ₂Base-emitter-base bandgap grading be connected to divider resistance R respectively ₃Two ends, simultaneously, also be connected in series a normal open switch K between the base-emitter-base bandgap grading of this triode ₅Ring language sheet in the warning circuit, amplifier integrated block 8050 passes through resistance R ₆Be connected to the colelctor electrode that promotes amplifying triode.By the electric-shocking circuit that KD4098, HU-1 constitute, one is terminated at the emitter-base bandgap grading that promotes triode, the same colelctor electrode that promotes triode that is connected to voice sheet input of the other end.Be located at the K switch of releasing on the body ₂With charging capacitor C ₃The two ends parallel connection, C ₁Shunt capacitance for charging circuit.

In the present embodiment, by the change resistance R ₁, C ₂, C ₃The choosing value can obtain the different time-delay charging intervals, to adapt to owner's time needs of unblanking and lock a door.Adopt the dc sources of 1.5 volts battery parallel connections of two four joints, 6V be provided voltage, but the short time provide 800 μ A electric currents, select KD4090, HU-1 and other corresponding values for use, can obtain predetermined high pressure electric current output, produce appropriateness and shock by electricity.

If select R for use ₁=100 kilo-ohms, C ₂=C ₃=1000 microfarads then can produce time-delay charging interval of 2 minutes, select 8050 integrated packages for use, mechanical oscillation of KD4098 model, and at charging resistor R ₁Two ends in parallel one by paralleling switch K ₃, K ₄With dropping resistor R ₂The branch road that series connection constitutes is with K ₃, K ₄And K ₂Be arranged on together on the body, can make the thief can't judge that switch is the charge discharging resisting K switch ₂Because R ₂, K ₃Or K ₄, C ₂, C ₃Form quick-charging circuit, so can prevent to push K in turn because of the burglar ₂, K ₃, K ₄Switch loses electronic anti-theft door to ring and reports to the police and electric shock effect R ₂=100 Europe.Make a false report alert phenomenon in order to prevent that the frequent switch door of owner from not producing.In the present embodiment, also at C ₁, C ₂The anode serial connection repid discharge diode D of electric capacity ₁
