Abstract
The utility model involves a strip, concretely, a mobile phone chain belt with alarm function. The utility model includes a chain belt, characterized in that: lead which is connected with a controller is contained in the lining of the chain belt; a switch and an alarm are installed in the controller whose bottom is connected with a connector. The utility model has advantages of simple structure and convenient usages, the utility model can timely warn as a thief is stealing the mobile phone, reminding people to avoid mobile phone theft.
Description
Technical field
Novel a kind of being linked with, the specifically a kind of mobile phone chain belt of relating to of this reality with warning function.
Background technology
Mobile phone is the mobile communications tool that people generally use, and brings great convenience for people's live and work.Now fashion, multi-functional mobile phone type emerge in an endless stream, and what be loved by the people chases after rod, but all mobile phones all can not be taken precautions against thief " evil backstage manipulator " effectively.Stolen in order to prevent mobile phone, people usually hang over the front with mobile phone by chain belt, mobile phone are stolen after protection still has the thief that chain belt is cut off even strengthen like this.Since people go window-shopping or ride the time general idea, cause the thief that loved mobile phone is stolen, live to people and brought inconvenience.Therefore inventing a kind of mobile phone chain belt with warning function prevents that hand-set from stolen will be highly profitable.
Summary of the invention
The purpose of this utility model is the defective at existing product, provides a kind of mobile phone chain belt with warning function, to remedy the deficiency of existing product.
This reality is novel to be achieved in that it comprises chain belt, is characterized in that: the internal layer of chain belt is surrounded by lead, and lead is connected with a controller, and controller is equipped with switch and alarm, and the bottom of controller is connected with a connector.Described alarm comprises two light-emitting diodes and a piezoelectric buzzer; The control circuit of described controller connects and composes direct coupling amplifying circuit by the collector electrode of triode Q1 and the base stage of triode Q2, piezoelectric buzzer 7 be attempted by between the collector electrode C point and power cathode of Q2 after light-emitting diode VD1 is connected in series VD2, lead is connected between the base stage and power cathode of triode Q1.
The utlity model has advantage simple in structure, easy to use, it can in time be reported to the police when the thief steals mobile phone, thereby reminds people is avoided hand-set from stolen.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the circuit working schematic diagram of controller.
Embodiment
Further specify novel structure of this reality and operation principle below in conjunction with accompanying drawing:
As shown in Figure 1, it comprises chain belt 1 the utility model, and the internal layer of chain belt 1 is surrounded by lead 2, and lead 2 is connected with a controller 3, and controller 3 is equipped with switch 4 and alarm, and the bottom of controller is connected with a connector 8, and connector 8 is connected with mobile phone 9.Described alarm comprises 5,6 and piezoelectric buzzers 7 of two light-emitting diodes; The control circuit of described controller connects and composes direct coupling amplifying circuit by the collector electrode of triode Q1 and the base stage of triode Q2, piezoelectric buzzer 7 be attempted by between the collector electrode C point and power cathode of Q2 after light-emitting diode VD1 is connected in series VD2, lead is connected between the base stage and power cathode of triode Q1.
The circuit diagram operation principle, as shown in Figure 2, the base stage of the integrated utmost point of triode Q1 and triode Q2 connects directly coupling amplifying circuit of formation, and R1, R2 are upper offset resistance, R3 is a load resistance, piezoelectric buzzer 7 be attempted by Q2 collector electrode C point after light-emitting diode VD1 is connected in series VD2.
As 2 of a, b during with 2 short circuits of the thin wire in the common chain belt, Q1 ends, the Q2 conducting, collector electrode C point electronegative potential (about about 0.3V), so buzzer 7 can not get voltage, sounding does not ring, all no-voltage is not luminous yet for VD1 and VD2 at this moment, when the thief cuts off chain belt, the Q1 conducting, Q2 ends, collector electrode C point high potential (about 6V), so buzzer 7 obtains voltage, sends the sound, this moment, VD1 and VD2 also obtained voltage and luminous warning.
