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 for supermarket etc. at present is " Electronic Article Surveillance "; Original text is " Electronic Article Surveillance ", is called for short " EAS ", and this system mainly is made up of three parts: the radio frequency detecting device; Demoder/decoding deck/nail-fetching device, soft label/hard label.
EAS system works principle: on commodity, paste soft label in advance or hard label (selecting different labels for use according to different commodity) is installed; The commodity of purchase of customer can be paid the bill at cashier under the normal condition, and at this moment the cashier can decode the commodity of band anti-theft tag or adopts nail-fetching device to unblank on decoding deck; 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market (for example theft of merchandise person) without the cash register passage, soft label or hard label through out-of-date, can make the radio frequency detecting device produce and report to the police in the antitheft door surveyed area, thereby realize the antitheft purpose.
In this system:
1, soft label/hard label (soft label is a disposable product, and hard label is reusable) sticks on the commodity or adopts to be bundled on the commodity usually, looks condition of merchandise and decides.
Soft label/hard label is actually " LC " oscillator (referring to that telefault and capacitor compose in parallel); Soft label adopts the aluminium foil flexible circuit to process; And hard label directly adopts copper cash and capacitor to process, 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), be installed in usually 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), be installed in usually 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 takes place; The voltage that this pulse signal takes place 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 is meant the circuit that demoder is inner is directly accomplished decoding deck with high-tech means inside; 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 decoding is highly higher, volume is littler; Use and install all easily, in particular cases also can be with a decoding deck again.
The nail-fetching device principle: mainly be made up 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 or the like) is installed in front door or cashier front usually.
The radio frequency detecting device mainly is made up of emitting antenna and receiving antenna, to accepting radio signal of antenna emission, makes wireless electromagnetic field scan district of generation between emitting antenna and the receiving antenna by emitting antenna.And anti-theft tag is processed 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 take place, just utilize this to change and make a signal that can produce warning.Detecting device divides two kinds, and one is emitting antenna, and another is a receiving antenna, must combined simultaneously and could be used by transmitter and receiver; Also can many emissions and many receptions 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, and it can detect the position at label place accurately, avoids the 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 rude situation such as client has a rude attitude.
At present, there are a series of problems in soft, hard label.Metal can shield the signal of soft label, thus soft label can not stick on the commodity that have metal material character, like canned milk powder, or the commodity of packing with metal materials such as masking foils; And hard label often adopts the mode that bundlees or pass commodity to be 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 the destruction to commodity for soft commodity.
Summary of the invention
In order to overcome the shortcoming that above-mentioned prior art exists; The object of the present invention is to provide a kind of antitheft hard label, the edge that is clamped in soft commodity that it can be firm need not pass commodity; Commodity are not damaged and can be by the metal material shielded signal, it is more reliable to guard against theft.
In order to address the above problem, the present invention adopts following technical scheme: this antitheft hard label comprises tapered end, purl, circuit part; Said circuit part comprises telefault, capacitor; Also comprise housing, housing comprises first intermediate plate, second intermediate plate;
Said first intermediate plate comprises first top, first bottom, and the base of the base on first top, first bottom is fixed in the first cylindrical both sides relatively; First top is being provided with the coil groove that is used to place said telefault, capacitor on the first cylindrical one side; The top on first top is provided with the cylinder that is used to install tapered end; First bottom is being provided with the clamping convexity on the first cylindrical one side; A first cylindrical end is coaxial to set firmly a rotating shaft;
Said second intermediate plate comprises second top, second bottom, and the base of the base on second top, second bottom is fixed in the second cylindrical both sides relatively; Second top is being made as the buckling surface that can snap together with first top towards the second cylindrical one side; The top on second top is provided with the stator corresponding with the tapered end position, and this stator is provided with the through hole of the purl that is used to plant; Second bottom is being provided with the clamping convexity on the second cylindrical one side; A second cylindrical end is provided with blind hole vertically, and the rotating shaft gap of first intermediate plate is inserted in this blind hole.
As further technical scheme of the present invention:
In this antitheft hard label, the top correspondence of said first intermediate plate, 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 fix and can any damage and destruction be arranged to commodity; Also solved the problem that soft label can not use at the commodity of metal materials such as masking foil packings (like milk powder in bags etc.); Promptly can be as soft label by mental package commodity shielded signal, anti-theft effect is more reliable.In addition, the hanging hole of setting more helps putting of commodity and has changed in the past anti-theft tag and only guard against theft, commodity are put the problem that has a negative impact.
