Embodiment Construction

[0010] The present invention will be further described below in conjunction with the accompanying drawings.

[0011] As shown in the drawings, the anti-theft bag of the present invention includes a bag body and an alarm circuit installed in the bag body. The alarm circuit includes a power supply 1 connected in series, a switch 2, an adjusting resistor 3 and an RC oscillating circuit. The RC oscillating circuit is composed of a resistor 4 , capacitor 5, loudspeaker 6 and metal lock resistor 7 are connected in series to form a closed circuit; switch 2 is a lock-type metal lock, and the lock-type metal lock is installed at the seal of the bag body; power supply 1 is a low-voltage direct current composed of dry batteries power supply.

[0012] When the anti-theft bag of the present invention is in use, the alarm circuit is installed in the bag body, and the switch 1 of the bag body is a lock-type metal lock, and the lock-type metal lock is installed at the sealing place of the bag...

Abstract

The invention discloses an anti-theft bag, which comprises a bag body and an alarm circuit which is arranged in the bag body, the alarm circuit comprises a power supply, a switch, a regulating resistor and an RC oscillation circuit, and the RC oscillation circuit is a closed circuit which is composed of a resistor, a capacitor, a loudspeaker and a metal lock resistor that are connected in series. The anti-theft bag has advantages of simple structure and convenient use, the alarming aim is achieved by the alarm circuit which is arranged in the bag body, the loudspeaker can be controlled by capacitor charging and discharging to give out alarm sound at the right time, thus preventing a thief from stealing things in the bag and avoiding property loss effectively.

Description

technical field [0001] The invention relates to a bag, in particular to an anti-theft bag with an alarm function. Background technique [0002] Bag is an indispensable article in people's daily life and work, which can be used to hold various items and can be carried around. However, due to people's negligence, the items in the bag are often stolen by thieves unknowingly. In order to have anti-theft function, some bags are equipped with anti-theft devices. But existing anti-theft devices are complex in structure, use loaded down with trivial details, and anti-theft effect is bad, useless; Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides an anti-theft bag with an alarm function. [0004] Technical solution: In order to achieve the above purpose, an anti-theft bag of the present invention includes a bag body and an alarm circuit installed in the bag body. The alarm circuit i...
