Abstract
The utility model relates to a sound magnet theft proof label resisting pressure and jamming, pertaining to a commercial adopting theft proof protecting alarming device, which comprises a case body, a case cover, and a resonation sheet and a soft magnetic bias sheet which are arranged in the case body. The sound magnet theft proof label is provided with a strengthened structure. The utility model is characterized in resisting pressure and jamming, not only guaranteeing the alarming effect, but also being able to be compressed into the packaging case plank or injected into the plastic commodity shell so as to greatly simplify the label sticking workload and enlarge the applying scope of the sound magnet theft proof label. As adopting a bias and case body or cover body integrated structure, the utility model has simple structure, convenient production and low cost.
Description
Technical field
The utility model relates to a kind of commercial anti-theft protection warning device, especially relates to the jamproof acoustic magnetic anti-theft label of a kind of resistance to compression that a kind of bias slice adopts soft magnetic material to make.
Background technology
The sound magnetic technology has been widely used in electronic item and has monitored that anti-theft device reached for two more than ten years, it is to utilize some amorphous alloy material strip because of having very high magnetic-elasticity coupling coefficient, so can send the principle of strong resonance signal develops, and it successfully is applied to commercial burglary-resisting system (sound magnetic system), as the burglary-resisting system of large supermarket.The sound magnetic system mainly comprises detector, demoder, anti-theft audio magnetic target etc.Present anti-theft audio magnetic target can be divided into two kinds: hard target of anti-theft audio magnetic and anti-theft audio magnetic label.I have put down in writing the innovation and creation that a kind of bias slice adopts the soft magnetism anti-theft audio magnetic label that soft magnetic material [the direct current coercive force is less than 1000A/m (12.5 oersted)] makes in the utility application file of application number 200620104764, these soft magnetism anti-theft audio magnetic label innovation and creation comprise long and narrow box body, the magnetic bias sheet, the resonance plate that is provided with in the box body, can be stamped the lid of forming by double faced adhesive tape and epiphragma on the box body, described epiphragma, magnetic bias sheet and resonance plate are layered arrangement, it is characterized in that described magnetic bias sheet is the soft magnetism bias slice, described resonance plate is straight schistose texture, and described resonance plate is at least a slice.Accompanying drawing 1 and Fig. 2 are the structural representation of one of embodiment of these innovation and creation, have kept flat a slice soft magnetism bias slice 3 among Fig. 1,2 in the cavity of the box body 1 of rectangular shape, soft magnetism bias slice 3 be shaped as straight rectangle.A slice resonance plate 2 is placed in the top of soft magnetism bias slice 1, is stamped lid 4 on the box body 1, and the outside surface of lid 4 can be provided with double faced adhesive tape as required.Because the box body and the lid of this soft magnetism anti-theft audio magnetic label are made by PVC plastic materials such as (Polyvinylchloride), when the end face of audio magnetic label and bottom surface are subjected to artificially having a mind to or when exerting pressure or coming from the outside other stronger pressure unintentionally, the resonant frequency of acoustic magnetic anti-theft label is changed or depressed, cause the afunction of reporting to the police.
The utility model content
The utility model fundamental purpose is to overcome above-mentioned the deficiencies in the prior art, provide a kind of simple in structure, cost is low, easy to process, save material, can resistance to compression and jamproof acoustic magnetic anti-theft label.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals: the jamproof acoustic magnetic anti-theft label of a kind of resistance to compression, comprise box body, lid, place resonance plate and soft magnetism bias slice in the box body, it is characterized in that described acoustic magnetic anti-theft label also is provided with the enhancing structure;
As preferably, described enhancing structure is set in the box body for strengthening cover, strengthening, and described resonance plate strengthens in the cover for one or more pieces are enclosed within, described enhancing cover is made by rigidity nonmetallic materials or non-ferromagnetic metal material, and described soft magnetism bias slice adds placement with the enhancing intussusception;
As preferably, described soft magnetism bias slice is combined into one with strengthening cover, and described enhancing cover is made by the biasing metal material;
As preferably, described box body and lid are made by the non-ferromagnetic metal material, and described enhancing structure is for strengthening muscle, described enhancing muscle frame and vertically distributing at the bottom of box around the lid;
As preferably, described box body or lid are made by the biasing metal material, and described soft magnetism bias slice is integrated with box body or lid respectively;
As preferably, described enhancing cover is the cylindrical body of rectangle for xsect;
As preferably, the wall of described enhancing cover is latticed;
As preferably, be coated with double faced adhesive tape on the described lid;
As preferably, described soft magnetism bias slice is made with iron-based or nickel-base alloy.
The utility model compared with prior art has the following advantages: 1, resistance to compression, owing to be provided with the enhancing structure, the acoustic magnetic anti-theft label anti-pressure ability is improved greatly, and not only can prevent artificial exerting pressure; Guarantee the warning effect, and can directly be pressed into acoustic magnetic anti-theft label in the packaging boxboard or be injected in the plasticity commodity housing, thereby simplify the labeling workload greatly, enlarge the range of application of acoustic magnetic anti-theft label.2, anti-interference, because label can resistance to compression, so label can prevent the warning performance of the interference label that the commodity stealer is artificial effectively.3, owing to adopt bias slice and box body or lid integral structure, make structure more simple, easy to make, cost reduces.
