The specific embodiment
With reference to accompanying drawing.Clip anti-theft device for commodities provided by the utility model; comprise the mechanism for double-layered quilt protection commodity; be provided with warning circuit in the described anti-theft device for commodities, be used in the situation that the situation of not unblanking firmly anti-theft device for commodities to be removed from the protection commodity is reported to the police.
Described warning circuit is provided with control chip 10, Magnetic Sensor 20, alarm mechanism and switch 30; Described alarm mechanism has comprised audible alarm mechanism 41 and luminous alarm mechanism 42 in the present embodiment, and perhaps optional one also can.Described Magnetic Sensor 20 can adopt Hall element.
Described switch 30, Magnetic Sensor 20, audible alarm mechanism 41 and luminous alarm mechanism are connected and all are connected with control chip 10; Described switch 30 be used for to protected commodity and anti-theft device for commodities be connected and disengaging is reacted, described Magnetic Sensor 20 is used for induction anti-theft device for commodities magnetic field on every side.
After anti-theft device for commodities of the present utility model is at the beginning or unblanks with the magnetic lockaid gun (state that is equivalent to Fig. 2); No. 7 pin of control chip are input as high level; at this moment; there is not the protective emblem position in the control chip; control chip is in sleep state; after anti-theft device for commodities is connected on the article (being the state of Fig. 1); switch 3 is depressed by protected commodity 100 and closure; No. 7 pin of control chip become low level from high level; anti-theft device for commodities enters guard mode; simultaneously, produce a protective emblem position in the control chip.After this, two kinds of situations are arranged:
1, normally unblanks, be that the lock core 200 of anti-theft device for commodities is near the magnetic lockaid guns and release, at this moment, Magnetic Sensor 20 in the anti-theft device for commodities also is in the magnetic field of magnetic lockaid gun, by its induction, No. 4 pin corresponding with output Magnetic Sensor control chip 10 become low level from high level;
At this moment, commodity and goods protection device are separated (state that is equivalent to Fig. 2), switch 30 disconnects, and No. 7 pin of control chip become high level from low level, are normal release, and control chip control alarm mechanism is not reported to the police;
2, when normally unblanking to remove goods protection device by force for employing magnetic lockaid gun; Magnetic Sensor is not experienced the magnetic field of magnetic lockaid gun; No. 4 pin of control chip are high level; because the protective emblem position is arranged; when commodity separate with goods protection device (state that is equivalent to Fig. 2); switch 30 disconnects; No. 7 pin of control chip become high level from low level; control chip control alarm mechanism is reported to the police; use again this moment the magnetic lockaid gun near Magnetic lockwork and Magnetic Sensor; No. 4 pin of control chip become low level from high level, can remove warning.
