Detailed description of the invention
Fig. 1 is elevation of the present utility model.The utility model comprises handcuffss, and handcuffss comprise fixing clasp 2 and movable clasp 1.Fixing clasp 2 end is provided with lock box 4.The end of movable clasp 1 is provided with latch hook 5.Movable clasp 1 and fixing clasp 2 are connected by connecting axle 3 and movable clasp 1 can rotate around fixing clasp 2.When handcuffss are copied in wrist, rotated by connecting axle 3 by movable clasp 1, until insert in lock box 4 to latch hook 5, handcuffss are locked.
Fig. 2 is stereogram of the present utility model.As shown in Figure 2, closed First Line box 7 is provided with inside fixing clasp 2.Fig. 3 is the stereogram in another direction of the present utility model.As shown in Figure 3, be provided with the second closed line box 8 inside movable clasp 3, First Line box 7 is connected with the space of the second line box 8 by connecting axle 3 inside.
Fig. 4 is the sectional drawing of connecting axle.As shown in Figure 4, be provided with First Line box 7 inside fixing clasp 2, inside movable clasp 1, be provided with the second line box 8.Movable clasp 1 is connected on fixing clasp 2 by the axle 3a in connecting axle 3, and movable clasp 1 and fixing clasp 2 can rotate around connecting axle 3 mutually.Threaded shaft 3a, have living space between movable clasp 1 and fixing clasp 2 3b.First Line box 7 is connected with the space 3b of the second line box 8 by connecting axle 3 inside.
Fig. 5 is that schematic diagram opened by handcuffss of the present utility model.As shown in Figure 5, lock box 4 inside is provided with the first circuit box 6, and the inside of latch hook 5 is provided with second circuit box 9.
The utility model also comprises handcuffss wrist strap, the first pontes, the second coupling part, processor and battery.Handcuffss wrist strap comprises holding wire around handcuffss wrist strap and fascination line, holding wire and to confuse the thickness of line, color, material identical.The first pontes, processor and battery are arranged among the first circuit box 6, and the second coupling part is arranged among second circuit box 9.
Fig. 6 is the circuit diagram of the first pontes.The first pontes comprises the first resistance R138.The first end of the first resistance R138 connects high level pin VDD_BT, and the second end connects warning pin ALARM and the first holding wire pin TP131.Warning pin ALARM connection handling device.Processor comprises wireless communication module.High level pin VDD_BT connects anode.
Fig. 7 is the circuit diagram of the second coupling part.Second coupling part comprises the second resistance R121.The first end of the second resistance R121 is by connecting the handcuffss earthing of casing, and the second end connects secondary signal wire pin TP133.
Second end of the first resistance R138 and/or second end of the second resistance R121 are provided with fascination wire pin.Fascination wire pin can arrange multiple.In the present embodiment, be provided with two fascination wire pins, and relative set two fascination line.Second end of the first resistance R138 is provided with the first fascination wire pin TP132, and second end of the second resistance R121 is provided with the second fascination wire pin TP134.
Fig. 8 is the schematic diagram of holding wire and fascination line.Composition graphs 6, Fig. 7 and Fig. 8, the first end of holding wire a connects the first holding wire pin TP131; The line body of holding wire a is successively through First Line box 7, the space of connecting axle 3 inside, the second line box 8; Second end of holding wire a connects secondary signal wire pin TP133.One end of first fascination line b connects fascination wire pin TP132, and the other end is vacant; One end of second fascination line c connects fascination wire pin PT134, and the other end is vacant.The line body of the first fascination line b and second fascination line c is through First Line box 7, the space of connecting axle 3 inside, the second line box 8.
At normal operation, holding wire pin TP131 and holding wire pin TP133 links together by holding wire, warning pin ALARM is in low level state, once handcuffss wrist strap is cut off or is removed, namely holding wire disconnects, namely holding wire pin TP131 and holding wire pin TP133 disconnects, and warning pin ALARM is driven high high level state instantaneously, and warning pin ALARM sends the state that this level changes to processor.
Spy software and wireless communication module are installed in processor.Spy software is an interrupt handling routine, when processor receives the information of warning pin ALARM level change, processor calls spy software code, after the level that spy software confirms warning pin ALARM is effectively changed, alarm signal can be sent to intelligent machine or other external equipments by wireless communication module, do further process by the latter.
Outside removing is directly cut off, handcuffss wrist strap also has a kind of common crack method, is holding wire and arranges bypass, then, after handcuffss wrist strap is cut off, holding wire, by bypass UNICOM, makes tester cannot discover handcuffss wrist strap by the situation of cutting off.But in the utility model, holding wire is only used to signal transmission, thus can do very thin, and can be when mounted, holding wire is bent repeatedly, simultaneously fascination line is set holding wire is other, because the features such as the color of holding wire and fascination line, thickness and material are all identical, then wired mixed in together, holding wire is made extremely to be difficult to identification, avoid wrist strap wearer and choose holding wire separately, bypass is arranged to it, abolish this situation of alarming apparatus.The present embodiment is provided with two fascination lines, also can arrange more fascination lines, increase identification difficulty.
When being difficult to directly recognize holding wire, the wearer of handcuffss wrist strap can also judge effective holding wire by the current information detected in each electric wire, in order to prevent the generation of this situation, the utility model also proposed more excellent technical scheme, namely the resistance of resistance R138 is set to 2M Ω, namely resistance R138 is as current-limiting resistance, can ensure that the electric current in holding wire is enough little like this, even if use instrument to be also difficult to detect, prevent the wearer of handcuffss wrist strap from detecting current information by using instrument and then judging useful signal line.
Above-described is only preferred embodiment of the present utility model, and the utility model is not limited to above embodiment.Be appreciated that the oher improvements and changes that those skilled in the art directly derive or associate under the prerequisite not departing from spirit of the present utility model and design, all should think and be included within protection domain of the present utility model.
