Description
Technical field
The utility model relates to the lockaid gun of the hard label of a kind of EAS of being used for system.
Background technology
Antitheft EAS (eas) system is a kind of anti-pilferage means and the system that widely uses in modern retail sector and environment.Can both see application in a lot of mass merchandisers, supermarket, discount chain store.The complete EAS system of one cover comprises several big ingredients: EAS hard label or soft label, the corresponding hard label lockaid gun and the demagnetizer or the code remover of soft label are located at the EAS monitoring aerial system at monitoring channel place in addition.EAS hard label or soft label are to be used for attached on all commodity of market, when commodity are sold at cashier, hard label will be taken off from commodity by special lockaid gun, soft label also has special demagnetizer or code remover to kill, otherwise have hard label or the commodity of the soft label of the magnetic that do not disappear will be detected by EAS monitoring aerial system when going out the EAS monitoring channel in market, and triggering system is reported to the police.
A kind of hard label lockaid gun in the market is a kind of " safety label and the supporting unlocking apparatus that bending channel is arranged " that discloses as in the United States Patent (USP) 5426419, as shown in Figure 1, its operating principle is to stretch into the shell 3A of hard label by the thimble 88 of a bending, the position 16 that promotes spring leaf then makes spring leaf 15 and 16 grooves that form broaden, thereby discharges the pin of being clamped by groove 4.The advantage cost of this hard label is low, but lockaid gun is the complex structure because mechanical thimble parts are arranged but, and big load mechanical movement for a long time, make thimble and transmission mechanism be easy to wearing and tearing, thereby reduction of service life greatly, reduce the reliability of lockaid gun, and increased plant maintenance maintenance cost after sale.Simultaneously on the other hand, hard label simple in structure also is easy to be cracked by the thief and opens, thereby a little less than the protection.
The another kind of lockaid gun of main flow and hard label are compared first kind owing to its advantage on the market, are adopted by retail sector more widely.This lockaid gun is to be specifically designed to the hard label of opening a kind of steel ball locking device, and as shown in Figure 2, whole locking device is by steel bowl 14, and steel ball 19 is formed, and the locking device that has also further comprises three hole stops 16 of a restriction steel ball position.At ordinary times, three hole stops 16 under the roof pressure of spring 18 and steel ball 19 all be pressed in the little head end of steel bowl 14, steel ball 19 is subjected to the microcephaly and holds 14 extruding of steel bowl, the shank 28 of the antitheft pin 24 in the middle of clamping simultaneously.
And lockaid gun 50 comprises one every the magnetic shell, should be every the built-in HHT higher high tensile magnetic core of magnetic shell, a magnetic conduction lid is close at the top of HHT higher high tensile magnetic core, the magnetic conduction lid of the top of HHT higher high tensile magnetic core by an irony conducts to the magnetic conduction cap top with the magnetic force of inner HHT higher high tensile magnetic core, and the top of magnetic conduction lid also has the corresponding recess of shell shape of projection at the locking device position of and hard label, can hold the locking position of label easily, can the align suction direction of HHT higher high tensile magnetic core of the three hole stops that guarantee the inner irony of hard label like this is shown in the figure arrow A.Under the suction of HHT higher high tensile magnetic core, three hole stops 16 can be pulled extrusion spring downward vertically, and the stub end of steel ball 19 bands to steel bowl 14, make steel ball can have bigger radial space to discharge the draw point of clamping.Compare with first kind of mechanical lockaid gun, such magnet lockaid gun structure is very simple, without any moving-member, because there is not the wear problem that works long hours of mechanical lockaid gun.So this lockaid gun cost is low, use reliably, long service life, because first kind of lockaid gun use of ratio is more extensive, occupation rate of market is higher.
The hard label of the second way is compared with the hard label of first kind of spring leaf, because the full hole of label except having only one can insert antitheft pin, label does not resemble the big opening first kind of hard label, stopped the possibility that the thief can touch inner locking device, so antitheft reliability is higher.But in actual the use, the high chi in discovery road, the high battle of evil spirit, the thief still can destroy label by other approach, such as after destroying the pin lid, takes off with the pin lid and peg the commodity clothing, destroys the shell of whole label in addition, thereby destroys inner locking device.On this basis, market begins to occur more advanced active electronics anti-theft tag, this label not only can be realized the locking commodity of traditional E AS hard label, and report to the police in EAS sense channel scope internal trigger EAS surveillance, also has inner circuit for detecting, can detect the behavior of thief, also have senior anti-theft features such as thief's tilting pin lid or destruction shell without the antitheft pin lid of illegally extracting of lockaid gun.But this active electronics anti-theft tag also is in the primary stage, and the standard that neither one is unified, function are also different, and lockaid gun also has nothing in common with each other.And exist the lockaid gun of the old and new's technology also incompatible, not general mutually at the lockaid gun of various hard labels yet.
