Description
Technical field
The present invention relates to the Electronic Article Surveillance technical field, especially the anti-theft tag in the Electronic Article Surveillance.
Background technology
As everyone knows, the burglary protection system for commodities that is used at present supermarket etc. is " Electronic Article Surveillance ", original text is " Electronic Article Surveillance ", be called for short " EAS ", this system mainly is comprised of three parts: the radio frequency detecting device, demoder/decoding deck/nail-fetching device, soft label/hard label.
EAS System Working Principle: paste soft label or hard label (selecting different labels according to different commodity) is installed at commodity in advance, the commodity of purchase of customer can be paid the bill at cashier under normal circumstances, and at this moment the cashier can unblank the commodity with anti-theft tag in decoding deck decoding or employing nail-fetching device; If instead directly just go out market (for example theft of merchandise person) without the cash register passage, soft label or hard label through out-of-date, can make the radio frequency detecting device produce and report to the police, thereby realize antitheft purpose in the antitheft door surveyed area.
In this system:
1, soft label/hard label (soft label is disposable product, and hard label is reusable) sticks on the commodity usually or employing is bundled on the commodity, decides on condition of merchandise.
Soft label/hard label is actually " LC " oscillator (referring to that telefault and Parallel-connected Capacitor form), soft label adopts the aluminium foil flexible circuit to make, and hard label directly adopts copper cash and capacitor to make, and centre frequency is consistent with the radio frequency detecting device all to be 8.2MHz.
2, demoder/decoding deck (a kind of equipment that soft label was lost efficacy, popular call: the demagnetization plate), usually be installed on the table top of cashier.Nail-fetching device (with a kind of instrument that hard label is taken off from commodity, popular call: lockaid gun), usually be installed on the cash register edge of table.
Demoder/decoding deck principle: decoding deck is to be contained on the table top of cashier, and its decoded signal is exported from demoder, and demoder is contained in the cashier the inside.Demoder mainly is that a high-tension pulse signal occurs, the voltage that this pulse signal occurs can be up to more than 300 volts, the capacitor of soft label the inside relies on this voltage breakdown, the electric capacity of soft label just is equivalent to its inductor and is in open-circuit condition after puncturing, so just can't produce signal.Integrated decoding deck refers to the circuit of demoder inside is directly accomplished with high-tech means the inside of decoding deck, an independent like this decoding deck has just possessed the function of decoding, and because there has not been connecting line to reduce line loss, so it is highly higher to decode, volume is less, use and install all easily, in particular cases also can be with again a decoding deck.
The nail-fetching device principle: mainly be comprised of magnet ring and magnetic core, both make up eddy current magnetic force of feasible one-tenth, and the magnetic force of common magnet surface is uniformly, but this structure of nail-fetching device makes magnetic force concentrate on the center of nail-fetching device, thereby the lock core of hard label can be opened easily.
3, radio frequency detecting device (popular call: anti-theft antenna, detecting gate, detecting device etc.) is installed in front door or cashier front usually.
The radio frequency detecting device mainly is comprised of emitting antenna and receiving antenna,, is made and produces a wireless electromagnetic field scan district between emitting antenna and the receiving antenna to accepting radio signal of antenna transmission by emitting antenna.And anti-theft tag is made with special process, make its same radio signal that produces a 8.2MHz with the radio frequency detecting device, because the oscillation action of this radio signal, make the electromagnetic field scanning area between emitting antenna and the receiving antenna that a variation occur, namely utilize this to change to make a signal that can produce warning.Detecting device divides two kinds, and one is emitting antenna, and another is receiving antenna, must be combined simultaneously and could be used by transmitter and receiver; Also can branched emission and the branched reception use that connects together.Also has a kind of hand-held detector, hand-held detector is actually one and integrates the detecting gate of receiving and dispatching, it mainly is the auxiliary detection equipment of client being searched the person and designing production for avoiding, it can detect the position at label place accurately, avoid contact inspection, after preventing effectively that detecting device from reporting to the police, the loss prevention personnel are to being accused of the generation of the rude situations such as client has a rude attitude.
At present, there is series of problems in soft, hard label.Metal can shield the signal of soft label, thus soft label can not stick on the commodity with metal material character, such as canned milk powder, or the commodity of packing with metal materials such as masking foils; And hard label often adopts binding or the mode of passing commodity is fixed on the commodity, can't realize then that for ganoid hard material it is fixed on the purpose on the commodity, then can cause destruction to commodity for soft commodity.
Summary of the invention
The shortcoming that exists in order to overcome above-mentioned prior art, the object of the present invention is to provide a kind of Anti-theft hard tag, the edge that it can firmly be clamped in soft commodity need not pass commodity, commodity are not damaged and can be by the metal material shielded signal, antitheft more reliable.
In order to address the above problem, the present invention by the following technical solutions: this Anti-theft hard tag comprises tapered end, purl, circuit part; Described circuit part comprises telefault, capacitor; Also comprise housing, housing comprises the first intermediate plate, the second intermediate plate;
Described the first intermediate plate comprises the first top, the first bottom, and the base of the base on the first top, the first bottom is fixed in the first cylindrical both sides relatively; The first top is being provided be used to the coil groove of placing described telefault, capacitor towards the first cylindrical one side; The top on the first top is provided with for the cylinder that tapered end is installed; The first bottom is being provided with the clamping projection towards the first cylindrical one side; A first cylindrical end is coaxial to set firmly a rotating shaft;
Described the second intermediate plate comprises the second top, the second bottom, and the base of the base on the second top, the second bottom is fixed in the second cylindrical both sides relatively; The second top is being made as the buckling surface that can be combined with the first upper buckle towards the second cylindrical one side; The top on the second top is provided with the stator corresponding with the tapered end position, and this stator is provided with the through hole for the plant purl; The second bottom is being provided with the clamping projection towards the second cylindrical one side; A second cylindrical end is provided with blind hole vertically, and the rotating shaft gap of the first intermediate plate is inserted in this blind hole.
As further technical scheme of the present invention:
In this Anti-theft hard tag, the top correspondence of described the first intermediate plate, the second intermediate plate is provided with hanging hole.
The invention has the beneficial effects as follows: it has changed the fixed form that hard label in the past passes commodity, it adopts the soft commodity of clamping edge not to be fixed and can any damage and fracture to be arranged to commodity, also solved the problem that soft label can not use at the commodity of the metal materials such as masking foil packings (such as milk powder in bags etc.), namely can be by mental package commodity shielded signal as soft label, anti-theft effect is more reliable.In addition, the hanging hole of setting more be conducive to putting of commodity changed in the past anti-theft tag only antitheft, commodity are put the problem that has a negative impact.
