Embodiment
The technological means adopted in order to reality object of the present invention is: a kind of anti-theft device, wireless launcher is positioned at fixed head, match with the wireless receiving alarm in fixing card, mutual transmission of signal, when wireless receiving alarm and wireless launcher are separated by beyond 3 meters, electronic chip in wireless receiving alarm is responded to, and sends sound signal, and amplifier to be set out alarm sound by loudspeaker after being amplified by signal; It is characterized in that: it is made up of fixed head, over cap, safety pin, fixing chain entrance, fixing chain draw-in groove, fixing card and button; Described fixed head is rectangular structure, and upper end face is provided with safety pin draw-in groove, and inside is provided with wireless launcher; Described over cap is positioned at fixed head upper end side, fixed head by gemel connection; Described safety pin is positioned at fixed head upper end face; Described fixing chain entrance is positioned at fixed head outer surface; Described fixing chain draw-in groove is positioned at fixing chain entrance lower end, and connected by chute, its inside is provided with jump ring; Described fixing card one end be connected to fixing chain, its inside is provided with wireless receiving warning device; Described button is positioned at fixed head dual-side, symmetrically structure distribution.
In the second embodiment described in Fig. 1, Fig. 2, over cap and fixed head upper end are connected; Fixing chain inserts by inlet slot, slides down in draw-in groove, then locked by jump ring along chute; Fixed head internal receipt wireless launcher, wireless launcher is connected with reset key.
In the 3rd embodiment described in Fig. 2, Fig. 3, Fig. 4, jump ring is positioned at draw-in groove, its inside symmetrically structure, and chuck is connected with connecting rod 1, is connected to spring in chuck lower end; Above connecting rod 1 two ends, be connected to spring, lower end is connected through the hinge connecting rod 3; Connecting rod 3 is connected to the connecting rod 4 that is connected through the hinge, and connecting rod 3 can at connecting rod 5 lower slide; Connecting rod 4 one end is connected to unlock key, and when pressing unlock key, connecting rod 4 driven forward be connected with unlock key, thus connecting rod 3 one Slideslip, make connecting rod 1 rotate, and drive chuck to rotate, jump ring is opened.
In the 4th embodiment shown in Fig. 2, Fig. 5, fixing chain one end is connected to fixing card, and fixing card can be connected with article, is provided with wireless receiving alarm in fixing card.
In the 5th embodiment shown in Fig. 6, Fig. 7, wireless transmitter circuits is made up of LF oscillator and high frequency oscillator; LF oscillator is made up of resistor R1, R2, capacitor C1, C2 and time-base integrated circuit IC1; High frequency oscillator is made up of variable resistor RP, inductor L1, resistor R3, R4, capacitor C2 ~ C9, wireless antenna W1 and transistor V1; Wireless receiving warning circuit is made up of wireless receiving treatment circuit and warning circuit; Wireless receiving treatment circuit is made up of wireless receiving integrated circuit (IC) 2, capacitor C10 ~ C19; Warning circuit is made up of sound effect integrated circuit IC3, transistor V2, resistor R5, diode VD and loudspeaker BL; After LF oscillator oscillatory work, the oscillator signal exporting 1KHz is modulated high frequency oscillator, and the high-frequency signal after modulation is launched by antenna W1 heavenwards; When the distance of wireless receiving alarm and wireless launcher is within 3m, the high-frequency modulation signal that W1 launches receives by antenna W2, then delivers to IC2 and carry out decoding demodulation process, makes the 2 pin output low levels of IC2, and IC3 can not triggering work, and BL is sounding not; If when the distance of wireless launcher and wireless receiving alarm is more than 3m, then wireless receiver alarm will can not receive the high-frequency modulation signal of W1 transmitting, and 2 pin of IC2 export high level, make IC3 be subject to triggering work, its audio electric signal exported, after V2 amplifies, drives BL to send chimes of doom.
When using of the present invention, the over cap of fixed head upper end is taken off, safety pin on fixed head is holded up, through pocket, being pressed into by safety pin in safety pin groove, cover over cap, insert article by fixing card, more fixing chain one end is inserted into porch, snap onto in draw-in groove along chute, pressing locking key, jump ring is being locked; When fixing card leaves at one's side more than 3m, wireless receiving alarm is responded to, and sends alarm sound, and card is fixed in finding of people's Energy velocity.
