Problems solved by technology

[0003] However, the use of infrared sensing is prone to misjudgment due to the influence of the surrounding environment. For example, when cockroaches and mice pass through the sensing area, the transmitter may be activated, causing the anti-theft alarm to suddenly emit a disturbing sound, making the anti-theft alarm impossible.

Abstract

The invention relates to a theft protection alarm start device, which comprises a sensitive switch provided with a main body, a linkage component and an arm. The linkage component can be positioned in the main body relatively in pivot swing mode; the arm is positioned in the linkage component in the mode of single direction pivot rotation; a transmitter is connected electrically to the sensitive switch; a wafer, which has a toggle section and can move along a first direction and a second direction; when the wafer moves along the first direction, the toggle section toggles the arm, the arm pushes the linkage component and the sensitive switch will start the transmitter; when the wafer moves along the second direction, the toggle section toggles the arm and the arm rotates along a single direction. Therefore, the invention can be installed on different doors to provide excellent practicality.

Description

technical field [0001] The invention relates to an anti-theft alarm, in particular to a starting device for an anti-theft alarm. Background technique [0002] There is a kind of anti-theft alarm that uses infrared rays for induction. When a foreign object passes through the infrared sensing area, a transmitter of the anti-theft alarm will be activated, and the transmitter will send a signal to activate the anti-theft alarm. In this way, the anti-theft alarm will be There will be a sound. [0003] However, the use of infrared sensing is prone to misjudgment due to the influence of the surrounding environment. For example, when cockroaches and mice pass through the sensing area, the transmitter may be activated, causing the anti-theft alarm to suddenly emit a disturbing sound, making the anti-theft alarm impossible. function as it should. Contents of the invention [0004] In view of the above problems, the main purpose of the present invention is to provide an activation ...
