Abstract

The utility model relates to an anti-theft device which consists of a machine body, sound outlet holes, a receiver, a purse, a transmitter, a transmitting circuit, a control circuit and an alarm circuit. The machine body is a square body; the upper end of the front side of the machine body is provided with sound outlet holes; the left lateral surface of the machine body is provided with the receiver; the purse is of a flat shape; the transmitter with a frequency transmitting function is arranged inside the purse; the transmitting circuit consists of a signal frequency diode VL, a resistor R1, a capacitor C1 and a switch S1; the control circuit consists of a sliding resistor RP, a resistor R3, a capacitor C2 and a switch S2; and the alarm circuit consists of transistors V1 and V2, a resistor R2, a chip IC and a speaker BL. After the anti-theft device is adopted, not only can the safety of the carry-on valuables be protected, but also people can have a relaxed and pleasant mood. The anti-theft device has a simple structure, is convenient to use and is suitable for people in various fields in modern life.

Description

Anti-theft device

Technical field

The utility model relates to a kind of device, especially a kind of anti-theft device.

Background technology

Along with the continuous development and progress of science and technology, human is rich, and the gap between the rich and the poor in the society is increasing, and some lawless persons just take advantage of the occasion to set about to people, will bring certain loss to people.Therefore, for self unnecessary loss, many families and more unit and group have all loaded onto warning system or anti-theft device.

In the face of growing society, potential safety hazard is also increasingly sophisticated.When the shop was stolen, the property of loss may make you arduous in vain 1 year, when family is stolen, possible loss be the wealth of you 1 year, 2 years even accumulation a lifetime.

Wallet is a most important parcel in our daily life as being with thing in people's daily life.Any wallet both had been fit to the identity of oneself, embodied the individual character of oneself again.Suitable wallet style more can embody your fashion index.

Along with various lawless persons' wildness, people in order to guarantee the safety of own valuables, constantly will take precautions against the valuable goods loss of carrying when going out.This will bring certain anxiety or uneasy sensation mentally to people, be unfavorable for the health of people's body and mind.

The utility model content

In order to overcome the deficiency of above-mentioned existing valuable goods loss, the purpose of this utility model is to provide a kind of anti-theft device, and it adopts transmitter is arranged in the wallet, receiver is arranged in the mobile phone, and by the loudspeaker of mobile phone alarm is sent.

In order to realize that the technical scheme that the purpose of this utility model adopts is: a kind of anti-theft device is characterized in that: it is made of body, sender, receiver, wallet, transmitter, radiating circuit, control circuit and warning circuit; Described body is a square body, and the front upper end is provided with sender, and left surface is provided with receiver; Described wallet is a flat, and inside is provided with the transmitter of frequency emission function; Described radiating circuit is made up of signal frequency diode VL, resistance R 1, capacitor C 1, switch S 1; Control circuit is made up of swept resistance RP, resistance R 3, capacitor C 2, switch S 2; Warning circuit transistor V1, V2, resistance R 2, chip IC, loudspeaker BL form.

The beneficial effects of the utility model are: it can either prevent that with oneself institute can bring the mood of loosening happiness to people again with the safety of valuables, and simple in structure, easy to use, is applicable to all kinds of personages in the modern life.

1-body, 2-sender, 3-receiver, 4-wallet, 5-transmitter among the figure.

Embodiment

In Fig. 1, Fig. 2, first embodiment shown in Figure 3, a kind of anti-theft device is characterized in that: it is made of body (1), sender (2), receiver (3), wallet (4), transmitter (5), radiating circuit, control circuit and warning circuit; Described body (1) is a square body, and the front upper end is provided with sender (2), and left surface is provided with receiver (3); Described wallet (4) is a flat, and inside is provided with the transmitter (5) of frequency emission function; Described radiating circuit is made up of signal frequency diode VL, resistance R 1, capacitor C 1, switch S 1; Control circuit is made up of swept resistance RP, resistance R 3, capacitor C 2, switch S 2; Warning circuit transistor V1, V2, V3, resistance R 2, chip IC, loudspeaker BL form.

In second embodiment shown in Figure 3, behind Closing Switch S1, S2, the entire circuit conducting; When body (1) and wallet (4) within the specific limits the time, V1 can receive the signal of VL emission, and IC is not worked, and BL does not report to the police; When body (1) and wallet (4) exceed when deciding scope, V1 can't accept the signal of VL emission, and V1 is transferred to IC place with the information that receives by V2, and IC is converted into electric signal with the signal of receiving and makes the BL conducting after the V3 amplification, and sounds the alarm.

When using the utility model, at first, the bluetooth of body (1) inner control receiver (3) switch is opened, the switch open of the interior transmitter of wallet (4) (5); Then, wallet (4) and mobile phone are put into carry-on sack respectively; When mobile phone or wallet (4) is stolen or other reason when separating certain distance, will go up sender (2) from body (1) and sound the alarm; When the switch of closing bluetooth inner control receiver (3), or close the switch of the interior transmitter of wallet (4) (5), or after the both closed, body (1) is activating alarm sound not.

Claims
