Abstract
The utility model relates to an acoustic-magnetic burglar hard tag which is composed of a case body, an amorphous resonance sheet, a bias magnetic sheet and a case cover; the case body is rectangle, the case body is smelted or pasted with the case cover, the case body has two structures: one cabin or left, middle and right cabins, and then the case body is connected with a protected commodity by a rope or a protective case with a locking device, seeing instruction book for details. The acoustic-magnetic burglar hard tag has the advantages that: the case body has one cabin or three cabins, the bias magnetic sheet is composed of neodymium iron boron material or ferrite material, a group of the bias magnetic sheets are used, and one bias magnetic sheet is used in the prior art, the mounting position of the bias magnetic sheet can be arranged at two ends of the amorphous resonance sheet or above the amorphous resonance sheet; the hard tag is thinner, the material usage is less and is one tenth of the bias magnetic sheet in the prior art, and compared with the acoustic-magnetic burglar hard tag in the prior art, the cost is low.
Description
Technical field
The utility model relates to eas system (EAS) and anti-theft tag, and specifically, the utility model relates to magnetic-mechanical electronic burglary protection system for commodities antitheft hard label of sound magnetic.
Background technology
Eas system is that to be widely used in supermarket, market, library, brand shop be the electronic installation that prevents that Retail commodity from losing.Eas system divides electromagnetic type (EM), RF-type (RF), magnetic-mechanical type (AM) three major types.
U.S. Pat 4510489, US4510490 disclose a kind of magnetic-mechanical electronic burglary protection system for commodities and acoustic magnetic anti-theft label.The acoustic magnetic anti-theft label of prior art (Fig. 3) is made up of amorphous resonance plate, biasing magnetic sheet, box body and lid.The biasing magnetic sheet is to be made by hard magnetic material or half-hard magnetic material.The magnetic coercive force of half-hard magnetic material is less, can be by magnetic sheet magnetize or the control that audio magnetic label is activated (warning) and passivation (not reporting to the police) is finished in demagnetization to setovering, and this audio magnetic label claims soft label.The magnetic coercive force of hard magnetic material is higher, can not fill it under the general condition, demagnetization, so hard magnetic material is in state of activation for the audio magnetic label of biasing magnetic sheet always.Such label claims hard label.By rope or have a latching system protect that box and protected commodity connect together,, separate label get off from commodity when passing through the detection zone of eas system legal by unlocking device.This hard label can use repeatedly.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of thinner, cost is lower antitheft hard label of sound magnetic is provided.
The technical solution of the utility model is as follows: the antitheft hard label of sound magnetic is to be made of box body, amorphous resonance group sheet, bias magnetic group sheet, lid; Box body is rectangle, fusion or bonding being integral between box body and the lid, and box body has two kinds of structures:
A kind of box body structure is a bin, places the amorphous resonance plate in the bin, on the amorphous resonance plate, places the biasing magnetic sheet, places lid above the biasing magnetic sheet, adds barrier film between magnetic biasing magnetic sheet and the amorphous resonance plate, also can not add barrier film;
Another kind of box body structure is three bins in left, center, right, and bin broad in the middle is placed the amorphous resonance plate, and bin small in ends is placed the biasing magnetic sheet, places lid at the amorphous resonance plate with above the biasing magnetic sheet;
Sound magnetic antitheft hard label is by rope or have protecting being connected of box and protected commodity of latching system.
Bias magnetic group sheet is made up of 2-4 magnetic sheet, the parallel two ends that are placed on the amorphous resonance plate or above, polarity of the magnetic field is arranged as NS-NS to NS-NS--NS--NS.
The biasing magnetic sheet is to be made of neodymium iron boron or ferrite permanent-magnet materials, and the biasing magnetic sheet is neodymium iron boron or ferrite sintered or rubber and plastic sheet or injection-molded plaques.
Amorphous resonance group sheet is made up of a slice, two or three amorphous resonance plates.
Barrier film generally uses nonmagnetic substance, and for example plastic foil, paper film etc. are by the distance between membrane thicknesses adjustment biasing magnetic sheet and amorphous resonance plate, to reach the purpose of adjustment amorphous resonance plate working point.
The utility model compared with prior art has following advantage: the utility model box body has one or three storehouses; The biasing magnetic sheet is to be made of the sintered sheets of NdFeB material or Ferrite Material or rubber and plastic sheet or injection-molded plaques, uses one group of biasing magnetic sheet simultaneously, and the prior art hard label uses a slice biasing magnetic sheet.Biasing magnetic sheet installation site can be placed on the two ends of amorphous resonance plate or amorphous resonance plate above; The utility model label thickness is 2-3mm, prior art label thickness is 3-5mm, make audio magnetic label become thinner, prior art biasing magnetic sheet size is 40 * 14 * 1 (mm), the utility model bias magnetic chip size is long 5-6mm, wide 4-5mm, thick 0.4-1mm (two), and material is used still less, has only 1/10th of prior art biasing magnetic sheet, with prior art audio magnetic label ratio, cost is lower.
When the utility model is applied for a patent, also applied for patent of invention, denomination of invention is biasing magnetic sheet, the preparation method and its usage in the antitheft hard label of bayonet type sound magnetic, and details is seen patent of invention.
