Abstract

The invention discloses an antitheft alarm device used in a desk drawer. The antitheft alarm device is composed of a 6V direct current power supply, a 555 time-base integrated circuit, a light-operated trigger loop and a sound load loop. The 6V direct current power supply separately provides power supplies for the 555 time-base integrated circuit and the light-operated trigger loop. The 555 time-base integrated circuit is separately connected with the light-operated trigger loop and the sound load loop. The invention reveals the antitheft alarm device used in the desk drawer. The antitheft alarm device is simple in structure, and low in cost. The antitheft alarm device employs a light-operated alarm technique. An alarm sound will be emitted when the antitheft alarm device is exposed to light, and a good effect of threatening and deterring thieves can be achieved.

Description

technical field [0001] The invention relates to an electronic device, in particular to an anti-theft alarm device used in a desk drawer, and belongs to the field of electronic technology. Background technique [0002] In enterprises and institutions, office theft incidents often occur. Thieves usually sneak into offices lacking anti-theft protection at night when there is no one there, and steal all kinds of property with the help of flashlights. In order to steal property in the desk, thieves usually use tools to forcibly break the locks on the drawers, pry open the drawers, and rummage through them. Items of value in a drawer. Some units with good conditions will install more advanced anti-theft alarm systems to prevent the office from being stolen, but many units with average conditions cannot install security anti-theft alarm systems in all offices, such as teachers' offices in schools, and even some offices will suffer multiple damages. The second theft, while bringin...
