Embodiment Construction

[0008] In the figure, the buzzer 1, the battery 3, and the switch 11 are respectively connected in series with wires 4 to form an unclosed series circuit, which is fixed on the flat bottom plate 2, and the fixing block 6 is fixed on the flat bottom plate 2. The fixed block 6 is connected with the conductive iron sheet 7 with the spring 5, the magnet 8 is fixed on the door edge 10, and the switch 11 is closed. When the door is closed, the distance between the door frame edge 9 and the door edge 10 is relatively small. 8. The conductive iron sheet 7 is adsorbed on the door frame edge 9. When the door is opened, the door edge 10 is separated from the door frame edge 9, the distance between the magnet 8 and the conductive iron sheet 7 becomes farther, and the magnetic force decreases. The pulling force of 5 is connected with the unclosed circuit, causing the circuit to be closed, the buzzer 1 sends a buzzing sound to alarm, and the warning door is opened.

Abstract

A simple antitheft alarm comprises a buzzer, a flat base plate, a battery, conductive wires, a spring, a fixed block, a conductive iron plate, a magnet and a switch. The simple antitheft alarm is characterized in that: the buzzer 1, the battery 3, the switch 11 are in series with each respectively through the conductive wires 4 to form an unclosed series circuit; the unclosed series circuit is fixed on the flat base plate 2; the fixed block 6 is fixed on the flat base plate 2; the fixed block 6 is connected with the conductive iron plate 7 through the spring 5; the magnet 8 is fixed on a door edge 10; the switch 11 is closed; when a door is closed, the distance between a door frame 9 and the door edge 10 is relatively small; because of the effect of a magnetic force, the magnet 8 adsorbs the conductive iron plate 7 to the door fame 9; after the door is opened, the door edge 10 is separated from the door fame 9; the distance between the magnet 8 and the conductive iron plate 7 increases, and the effect of the magnetic force decreases, so that the conductive iron plate 7 is connected with the unclosed circuit because of a tension effect of the spring 5, and accordingly the circuit is closed, and the buzzer emits a buzzing sound to carry out alarming, and a caution door is opened. The beneficial effects of the present invention are that: people can be cautioned that the door is opened, and thieves are prevented from entering; and the antitheft alarm is simple to make, and is energy saving and effective.

Description

technical field [0001] The invention belongs to a simple burglar alarm. Background technique [0002] In daily life, occasionally thieves open or pry open the door of the house, unknowingly enter the room to steal property, because the thief's movements are relatively light, it is generally difficult to be noticed by people. General family does not have alarm device, and alarm device is also more expensive now on the market. Contents of the invention [0003] The technical problem to be solved by the present invention is a simple burglar alarm. [0004] The technical solution adopted by the present invention to solve the technical problem is: a simple and easy burglar alarm, comprising a buzzer, a flat bottom plate, a battery, a lead, a spring, a fixed block, a conductive iron sheet, a magnet, and a switch. It is characterized in that the buzzer 1, the battery 3, and the switch 11 are respectively connected in series with wires 4 to form an unclosed series circuit, which...
