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
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
