Description
Technical field
The utility model relates to a kind of commercial anti-theft protection warning device, especially relates to the sound magnetic theft-prevention clamp that a kind of available magnetic is unblanked.
Background technology
The sound magnetic technology has been widely used in burglary-resisting system, the sound magnetic system mainly comprises detector, demoder and verifier, anti-theft audio magnetic target etc., the pulsating wave of detector emission certain frequency, excite the anti-theft audio magnetic target of in search coverage, not decoding to make it be detected device and detect, trigger alarm equipment alarm at this frequency resonance very strong signal of generation.Present anti-theft audio magnetic target can be divided into two kinds: anti-theft audio magnetic folder and anti-theft audio magnetic label, and both all use amorphous ribbon as resonance plate, and the crystalline state magnetic material is a bias slice.
Widely used in the market sound magnetic theft-prevention clamp can reduce two kinds simply by (the getting nail) mode of unblanking: mechanical type (getting nail) theft-prevention clamp and magnetic (the getting nail) theft-prevention clamp of unblanking of unblanking.But the mode of unblanking of existing sound magnetic theft-prevention clamp (pressing from both sides and the UltraGator folder as the SuperTag series that the U.S. money of U.S. elder generation news Sensormatic Electronics Corporation is produced) must adopt non-magnetic machinery (contact) formula to unblank, because the high-intensity magnetic field that magnetic lockaid gun inner magnet is produced can damage the direction of magnetization of isotropy biasing member in the sound magnetic burglar alarm parts (comprising resonance plate and isotropy plastic cement ferrite permanent-magnet biasing member).That is to say, because inhaling the magnetic field of the magnet (commonly used is rare-earth permanent magnet) of driving spring leaf in the magnetic unlocking apparatus can be up to 4000-6000 oersted (Oe), and the biasing member employing of existing sound magnetic theft-prevention clamp (pressing from both sides and the UltraGator folder as the SuperTag series that U.S. elder generation news U.S. money SensormaticElectronic Corporation is produced) is isotropy plastic cement ferrite permanent magnet, its coercivity H is only for about about 2000-3000 oersted (Oe), so the high-intensity magnetic field remagnetize of very easy quilt mixed and disorderly bending direction departs from originally the direction of magnetization along resonance plate length to new direction, thereby cause magnetic warning piece to be reduced to not alarm condition, caused permanent damages sound magnetic theft-prevention clamp warning performance from activated state.Therefore, sound magnetic theft-prevention clamp can only adopt the mechanical unlocking device of no magnetic in the past.Compare with the non-contact type magnetic unlocking method, mechanical unlocking device is complicated, manufacturing cost height, thereby the very fragile high maintenance costs that causes of mechanical push rod head, method for unlocking is that contact is not easy to the salesman and unblanks very much, these drawbacks limit the cost of sound magnetic theft-prevention clamp reduce and the market occupancy.The warning piece of present sound magnetic theft-prevention clamp adopt permanent magnetic material be the direct current coercive force greater than 1000A/m (125 oersted) magnetic material (for example permanent-magnet ferrite) as bias slice, resonance plate and bias slice separate stack respectively and are placed in the cavity of a clamp.At present except the U.S. money of news company of elder generation can produce the sound magnetic theft-prevention clamp of above-mentioned integral body, other magnetic theft-prevention clamp manufacturer is not owing to all possess the ability of making qualified resonance plate and bias slice, therefore must buy the sound magnetic warning piece of independent anti-demagnetization earlier, again it be put into or paste into and make magnetic theft-prevention clamp in the magnetic theft-prevention clamp.But desirable like this warning piece does not provide in the market, uses so some hard label production company have to adopt the soft label of existing sound magnetic to substitute real permanent warning member reluctantly.It is that the magnetic material of direct current coercive force between 1000A/m (12.5 oersted) and 10000A/m (125 oersted) is as bias slice that the present soft label of sound magnetic all adopts half-hard magnetic material, the DR label of the U.S. money of for example first news company, the original purposes of the soft label of this class anti-theft audio magnetic (hereinafter to be referred as audio magnetic label) is to adopt the mode that can decode repeatedly and activate, and the method that the audio magnetic label on the commodity of having paid money is decoded by demagnetization on demoder allows commodity leave the shop and can not trigger the alarm on doorway.But then exist as the warning piece of repeatedly used sound magnetic theft-prevention clamp and to be easy to the critical defect that caused magnetic theft-prevention clamp to lose efficacy by demagnetization.
In addition, also having occurred some in recent years on the market, central resonance frequency is housed is that the theft-prevention clamp of 58 kilo hertzs LC resonance section replaces magnetic theft-prevention clamp, though can unblank with magnetic, but it is very easy in metallic shield, also very easy high impulse by the high voltage of RF label puncture device common on the market or sound magnetic detection system punctures electric capacity and causes permanent failure. and wherein the LC parts have heavier ferrite iron core and copper cash, this class theft-prevention clamp is more thick and heavy, does not have sound magnetic theft-prevention clamp of the present invention light and handy.
Existing audio magnetic label (referring to U.S. Pat 6359563), comprise a long and narrow plastic box body and lid lid thereon, lid is formed by stacking by the bias slice and the epiphragma of epiphragma, double faced adhesive tape, half-hard magnetic material from top to bottom successively, the resonance plate of the mutual superposition that above size of placement a slice or a slice and box body are complementary in the cavity of box body, the horizontal archwise of resonance plate, wherein bias slice is the parallelogram or the parallelogram of chamfering.Existing audio magnetic label all adopts half-hard magnetic material to make bias slice; if make magnetic theft-prevention clamp with the DR label as warning piece reluctantly; because interference that can enough external magnets changes or eliminate the magnetic of audio magnetic label, make the sound magnetic theft-prevention clamp that this audio magnetic label is housed lose efficacy and can not excite the alarm on doorway, shop when making protected commodity be taken out of the shop.Thereby lost the defencive function of sound magnetic theft-prevention clamp.
In addition, existing sound magnetic theft-prevention clamp, its warning piece just is identical with the intermediate plate cavity size, promptly warning piece is just inserted in the intermediate plate cavity, in cavity, can't move or mobile space minimum.But permanent magnet bias sound magnetic warning member is different with the label of soft magnetism biasing or semihard magnetic bias, and because of the magnetic field gradient of permanent magnetism is very big, the variation of the relative position of its resonance plate and biasing member is just bigger to the influence of frequency.After theft-prevention clamp is unblanked, promptly through after being exposed to the high-intensity magnetic field of lockaid gun, resonance plate in it may be drawn onto the position of leaving biasing member by high-intensity magnetic field, but after leaving lockaid gun, very light resonance plate is difficult for overcoming friction and it is set back under the magnetic field suction of biasing member after the displacement, thereby resonant frequency is had greatly changed, cause alarm distance significantly to shorten, when reusing, often need permanent magnetism sound magnetic theft-prevention clamp beaten resonance plate is set back under the magnetic field suction of biasing member, otherwise can influence alarm distance, alarm distance can obviously reduce, very inconvenient, or stealer is had an opportunity to take advantage of.
The utility model content
The utility model mainly is in order to solve above-mentioned technical matters, a kind of simple in structure, stable performance, reliable to be provided, having outstanding interference free performance, and can guarantee the magnetic theft-prevention clamp of the available taking nail by magnetic unlocking method of alarm distance.
The above-mentioned technical matters of the utility model is mainly solved by following technical proposals:
The sound magnetic theft-prevention clamp that a kind of available magnetic is unblanked; comprise upper clip, lower clamping piece; the nail lock of the goods that locking will be protected; be provided with the intermediate plate cavity between upper clip and the lower clamping piece; magnetic warning piece is housed in the intermediate plate cavity, is provided with between described warning piece and the intermediate plate cavity and can makes the space of magnetic warning piece 3 D auto activity.
Leave certain space between warning piece and the intermediate plate cavity, because sound magnetic warning member integral body is more than the resonance plate recuperation, can be easily different and constantly free movable under action of gravity in the intermediate plate cavity with the dimensional orientation of theft-prevention clamp, so resonance plate just has an opportunity easily to set back under the magnetic field suction at permanent magnet bias spare when the stirring of warning member, and alarm distance was with unaffected when sound magnetic theft-prevention clamp was reused.
Sound magnetic warning piece comprises box body, biasing member, resonance plate and lid, resonance plate is enclosed in the cavity of box body, lid covers on box body, lid and resonance plate are layered arrangement, and biasing member only is arranged at the one-sided of resonance plate, and the length direction of biasing member and the length direction of resonance plate are in the same way, biasing member is made by the rare-earth permanent magnet of sintering, it is coercivity H 〉=7000 oersteds along its length, and an end and resonance plate one end of biasing member are substantially flush, and the length of biasing member is less than the length of resonance plate.
Biasing member is made by the rare-earth permanent magnet of sintering, coercivity H 〉=7000 oersteds, biasing member is that hard magnetic material and coercive force are bigger, and the Surface field of inhaling the magnet of driving spring leaf in the magnetic unlocking apparatus is 4000-6000 oersted (even the remanent magnetism of magnet is 12000 Gausses), so biasing member can not demagnetize by this high-intensity magnetic field, or remagnetize departs from originally the direction of magnetization along resonance plate length to new direction.All be in the past with biasing member with sheet and resonance plate with layered arrangement, permanent magnet bias spare produces strong clamping action to resonance plate and reduces resonance amplitude, especially the rare earth permanent magnet biasing member of resonance plate like this, its clamping action is stronger.Buttress shaft shape biasing member is fixed on resonance plate edge one side, its length direction is parallel to the resonance plate length direction also basically on the plane of resonance plate, though the multi-disc resonance plate can be held this side, but the length direction free vibration of resonance plate is also unaffected, the multi-disc resonance plate can not produce high friction when vibration as the sheet bias slice is inhaled into a slice during by layered arrangement with resonance plate, but seldom friction mutually.We have just solved this difficult problem that permanent magnetism in the past causes the strong clamping of resonance plate like this, and can relieved employing the strongest permanent magnet such as sintered rare-earth permanent magnetic are done biasing member and unblanked to get the sound magnetic theft-prevention clamp of nail to make available magnetic.Biasing member is long can to increase manufacture difficulty and material cost.
As preferably, the length and width of intermediate plate cavity and highly have more 1mm at least than the length and width and the Gao Ge of sound magnetic warning piece at least.Warning piece and intermediate plate cavity periphery leave the wide gap of 1mm at least, can make warning piece that the space of fully moving is arranged, and the alarm distance of assurance sound magnetic theft-prevention clamp after magnetic is unblanked is unaffected.
As preferably, biasing member is shaped as rod shape or strip, biasing member be fixed on box body outer in box body or injection moulding be fixed in the box wall of box body, described resonance plate is a slice or more than a slice.Rare earth permanent-magnetic material is fragility normally, is difficult to cold working, is unsuitable for making the strip bias slice, and rod shape or strip manufacturing process are simple, avoided this shortcoming of rare earth permanent-magnetic material.Biasing member both can be arranged on outside the box body, also can be arranged in the box body, as long as it is at the resonance plate side, it is less that the strength of resonance is influenced by it, and signal intensity is bigger.Biasing member also can be fixed in the box wall of box body in injection moulding in addition, then can fix biasing member simultaneously when making box body, has reduced manufacturing process flow.The resonance plate number is not limited to a slice, can make resonance signal intensity bigger as required.
As preferably, the length of biasing member is the 1/3-2/3 of resonance plate length.The length of biasing member is when resonance plate length 1/3-2/3, and is less to resonance plate vibration effect.
Biasing member is Sintered NdFeB or Sm-Co rare earth permanent magnet.Nd-Fe-Bo permanent magnet material is the known the highest permanent magnetic material of magnetic energy product, because it has the good ratio of performance to price, has promoted miniaturization, the lightness of warning piece.Even stealer wants that destroying biasing member with a very strong NdFeB or Sm-Co rare earth permanent magnet can not succeed to reach the purpose of destroying this magnetic theft-prevention clamp.
The beneficial effect that the utility model brings is: because the utility model is provided with the space between intermediate plate cavity and warning piece, can exempt the inconvenience that needs tap-tap magnetic theft-prevention clamp during repeated use, the alarm distance of magnetic theft-prevention clamp will can not reduced.And warning piece has not the advantage that can be destroyed by high-intensity magnetic field, and the amplitude that resonates simultaneously is also unaffected, so be not only applicable to mechanical lock-opening style sound magnetic theft-prevention clamp, is specially adapted to magnetic lock-opening style sound magnetic theft-prevention clamp, and it is simple in structure, low cost of manufacture.
