Abstract
The utility model relates to an anti-theft mobile phone cover comprising a cover. The utility model is characterized in that: an anti-theft device is arranged on the cover, and the anti-theft device consists of electric elements, namely an inductor, a triode and resistors R1, R2 connected with the inductor, a vibrator and a normal open switch. The emitter of the triode is connected with one end of the resistor R1, the positive pole of a power supply, and the inductor, the base electrode of the triode is connected with one end of the resistor R2 and the vibrator, the other end of the resistor R2 is connected with the vibrator, one end of the resistor R1, the inductor and the negative pole of the power supply, the collector of the triode is connected with one end of the normal open switch C1 and the inductor, and the other end of the normal open switch is also connected with the inductor. The circuit structure of the utility model provides true anti-theft protection for mobile phone, and the utility model has the advantages of a simple and feasible structure, low cost and easy use.
Description
The utility model relates to anti-stealing device for handset, specifically a kind of antitheft mobile phone cover.
The hand-set from stolen incident takes place often at present, and is particularly stolen easily especially with crowded public place on bus.And existing anti-stealing device for handset or too complicated, or use inconvenience, in fact do not reach antitheft being used as.
The purpose of this utility model provides a kind of antitheft mobile phone cover that better anti-theft feature is arranged.
The utility model is achieved in that the antitheft mobile phone cover, comprise cover, it is characterized in that cover is provided with anti-theft device, this device is made of electric elements, promptly reach triode and the resistance R 1 that connects with it by inductor, R2, and vibrator and Live switch formation, the emitter of triode and R1 one end, positive source and inductor connect, transistor base connects with an end and the vibrator of resistance R 2, the other end of resistance R 2 and vibrator, one end of resistance R 1, inductor and power cathode connect, the collector electrode of triode connects with an end and the inductor of Live switch C1, and the other end of Live switch connects with inductor.
Cell-phone cover of the present utility model is that above-mentioned whole circuit are installed on the cell-phone cover, easily assembling, adopt the normal open Closing Switch that opens circuit, and be contained on the lid of cell-phone cover, on the cover of this corresponding position, there is magnet to buckle, with below roller iron control upper switch, when uncapping, vibrator in the circuit will produce vibration, and prompting machine master cell-phone cover is opened by the people.Adopt vibration prompt not disturbed by outside noise, just can not send continuous interruption vibration prompt during complete opening at cell-phone cover, once full lid can send after opening 1 second of continuous shaking then repeatedly 3-4 lasting 1 second continuous shaking warn.The normal open Closing Switch that opens circuit can not stop to be interrupted vibration continuously when opening circuit, the continuous vibration in closed back is closed for 3-4 time automatically.If there is the human scissors to cut off connecting line, vibrator can be interrupted vibration prompt continuously.If the both sides Connecting line joint is thrown off, vibrator is understood continuous shaking equally and is reminded user's place under repair.Circuit structure of the present utility model can really play the antitheft effect of mobile phone, have simple for structure, characteristics such as cost is low, and is easy to use.
Fig. 1 is circuit theory diagrams of the present utility model;
Fig. 2 is a cell-phone cover belt fastener front view of the present utility model;
Fig. 3 is a cell-phone cover belt fastener rearview of the present utility model;
Fig. 4 is a cell-phone cover belt fastener end view of the present utility model.
Among the figure, 1-circuit board, 2-button cell, 3-vibrator, 4-punch holes, 5-belt fastener.
Below in conjunction with accompanying drawing the utility model is done further and detailed description, but be not limited to shown in the accompanying drawing.
Antitheft mobile phone cover of the present utility model is provided with anti-theft device by cover with on cover and constitutes.This device is made of electric elements, promptly by inductor and the triode 9w that connects with it and resistance R 1, R2, and vibrator and Live switch formation, the emitter of triode connects with R1 one end, positive source and inductor, transistor base connects with an end and the vibrator of resistance R 2, the other end of resistance R 2 connects with an end, inductor and the power cathode of vibrator, resistance R 1, the collector electrode of triode connects with an end and the inductor of Live switch C1, the other end of Live switch connects with inductor, as shown in Figure 1.Circuit board 1, vibrator 3, battery 2 all are installed on the cell-phone cover bracelet 5, shown in Fig. 2,3,4.
Used inductor is L88, is the commercially available prod.Vibrator also is to adopt prior art products.
