Abstract

The invention discloses an alarming device. The alarming device comprises a distance block fixedly disposed on a door frame and an alarming mechanism fixedly disposed on a door. The alarming mechanism comprises a thimble and an alarming circuit electrically connected with the thimble. The alarming circuit at least comprises an alarming device. When the door is in a closed state, the distance block is contacted with the thimble, and the alarming circuit is in a disconnected state. When the door is in an opened state, the distance block is separated from the thimble, and the alarming circuit is in a connected state, and the alarming device is triggered to give alarms. The problems of the conventional alarming devices such as lo w sensitivity, complicated equipment, and high production costs are solved.

Description

technical field [0001] The invention relates to an electronic anti-theft device, in particular to an alarm device. Background technique [0002] With the progress and development of society, thieves' theft methods are also emerging in an endless stream. After investigation, a large part of the theft cases happened when the homeowner was asleep at night. The thief opened the door lock and quietly entered the room to steal. Many homeowners were stolen. I didn't notice it at all. At present, various anti-theft devices are also emerging. The existing alarm device has a triangular shape on the side, and the trigger switch is on the slope of the triangle. When the door is closed, the alarm device can be placed under the door. Push the door and the frame of the door will touch the slope of the triangular alarm to trigger the alarm device. Although this device is simple, it is inconvenient to hold it back and forth and put it under the door every time, and it is easy to forget. Anot...
