Abstract

The utility model relates to an anti-theft alarming device, which is composed of an oscillator composed of a BG < 2 > and a BG< 3 >, a bistable oscillator composed of a BG < 4 > and a BG< 5 >, relays J < 1 >, J < 2 >, a high-voltage discharger composed of a D < 1-7 > and a C < 1-8 >, etc. When a house door is pried away, metal sheets E, F arranged on a door and a door frame are separated, and a sound generator sends out alarming signals; meanwhile, the metal sheet F discharges high voltage. The utility model has the advantages of simple structure and safe work performance. When the house door is pried away, the anti-theft alarming device can send out the alarming sounds, and discharges the high voltage.

Description

Burglar alarm
The utility model electronic technology field is a kind of burglar alarm.
At present, many families and office antitheft door all is installed, and most antitheft door are opened by the thief easily for antitheft, and safe coefficient is relatively poor.
The purpose of this utility model is to provide a kind of thief of working as to open behind the door and can give the alarm automatically, and can discharge the alarm device of high-tension electricity.
Solution of the present utility model is to adopt by BG 2, BG 3The oscillator of forming, BG 4, BG 5The bistable generator of forming, relay J 1, J 2By D 1-7, C 1-8The parts of forming such as effluve device constitute warning horn, and when door is pried open, be contained in sheet metal E, F on door and the doorframe and divide and open, the acoustical generator signal that gives the alarm, the while, sheet metal F was put high-tension electricity.
The utility model is simple in structure, and serviceability is safe and reliable, when door is pried open, the alarm sound equipment can take place, and can emit high-tension electricity.
The utility model is mainly by relay J 1, J 2, triode BG 1, BG 2, BG 3, BG 4, BG 5, diode D 1-7, capacitor C 1-8Constitute triode BG 2And BG 3Form oscillator, BG 4And BG 5Form bistable generator, D 1-7And C 1-6Form the effluve device, relay J 1One termination+6V direct supply, the other end meets BG respectively 1Base stage and BG 2Emitter, BG 3Emitter be connected with acoustical generator R, BG 1Emitter connect power supply, collector meets BG 4, BG 5Emitter, BG 5Collector connecting relay J 2, J 2The other end connects BG respectively 3Emitter and J 1Normally closed contact J 1-4, J 1-4Connect J 2Normally closed normal opened contact J 2-1The a point, J 2-1The c point meet D 1-7, C 1-8The effluve device, another termination AC power of effluve device V c, V cAnd between the effluve device J is arranged 1Normal opened contact J 1-1And J 1-2, J 2-1The b point meet sheet metal F, by door lock S, normal opened contact J 1-3W meets BG with dropping resistor 3Base stage.After connecting direct supply, J 1Energising, J 1-1, J 1-2, J 1-3Closure, J 1-4Disconnect BG 1Conducting, BG 4, BG 5Vibration, J 2Interrupted conducting, J 2-1B point and the interrupted make and break of a, c point, during the adhesive of b, c point, door and doorframe closure, F, E sheet contact, or open door lock S with key makes under the S conducting situation BG 3Base potential be higher than collector potential, BG 2, BG 3Nonoscillatory, R no power sounding: when door is pried open, under not conducting of the S situation, BG 2, BG 3Vibration, the R signal that gives the alarm is because D 1-7, C 1-8The effluve device connect the alternating current 220V power supply, make the F discharge, voltage can reach direct current 3000V because the interrupted adhesive of b, c point, F intermittently emits direct current, and the person is not had the injures and deaths infringement, the people gets an electric shock by electric current about 10mA.
