Abstract
The utility model provides a high stability merchandise anti-theft device, which comprises a housing which is internally provided with a noncrystalline magnetic sheet and a permanent magnet generating a bias magnetic field toward the noncrystalline magnetic sheet. When the high stability merchandise anti-theft device is in an alternation or DC high intensity magnetic field environment, the noncrystalline magnetic sheet does not demagnetize or is not magnetized reversely, thereby having good performance. The high stability merchandise anti-theft device solves the problem that the conventional and non-disposal anti-theft device with a noncrystalline EAS label loses effectiveness after approaching the magnetic field. In addition, the high stability merchandise anti-theft device has work stability and consistency higher than the common disposal or the non-disposal anti-theft device with the noncrystalline EAS label.
Description
Technical field
The utility model relates to the commodity anti-theft apparatus field.
Background technology
Leave the commodity on the open shelf of places of business such as supermarket in, exist the risk of illegally being taken out of the place of business.For this reason, businessman can be on commodity fixing anti-theft device, and be provided with the electronic article surveillance label that can transmit because of induction in the anti-theft device.Like this, when commodity by illegally being with when selling the place, the signal that electronic article surveillance label energy induction antenna door is launched and transmitting, thus can excite warning system.But in the time of in being in alternation or direct current high-intensity magnetic field environment, the signal that meeting makes the electronic article surveillance label (containing amorphous EAS label) of employing amorphous magnetic sheet be launched produces the frequency instability of frequency departure or signal, thereby influence the operate as normal of electronic article surveillance label, sometimes even can make its inefficacy.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of high stability commodity anti-theft apparatus that helps electronic article surveillance label operate as normal.For this reason, the utility model by the following technical solutions: it comprises housing, is provided with the amorphous magnetic sheet in the described housing, also is furnished with the permanent magnet that the amorphous magnetic sheet is produced bias magnetic field in the described housing.Because adopt the technical solution of the utility model, in the time of can making the utility model be in alternation or the direct current high-intensity magnetic field environment, the amorphous magnetic sheet can not demagnetize or be reversed magnetization, performance is intact.Solved alarm that conventional non-once contains amorphous EAS label near Problem of Failure behind the high-intensity magnetic field, job stability and consistance are higher than the alarm that common disposable and non-once contains amorphous EAS label in addition.

Embodiment
With reference to accompanying drawing 1,2.The utility model comprises housing 1, is provided with amorphous magnetic sheet 2 in the described housing, also is furnished with the permanent magnet 3 that the amorphous magnetic sheet is produced bias magnetic field in the described housing.Described commodity anti-theft apparatus is provided with lock construction 4, and described lock construction is located at an end of housing, and described amorphous magnetic sheet is located at the opposite side of housing.
Described bias magnetic field can adopt following arrangement to realize:
As shown in Figure 3, described permanent magnet is separately positioned on outside the two ends of amorphous magnetic sheet, and the described direction of arrow is the direction of permanent magnet field, promptly from the N utmost point to the S utmost point.This arrangement also is permanent magnet 3 arrangements of embodiment illustrated in figures 1 and 2.As shown in Figure 8, in this embodiment, the position of permanent magnet is identical with embodiment shown in Figure 3, but magnetic direction is opposite, and the direction of arrow is the direction of permanent magnet field among the figure, promptly from the N utmost point to the S utmost point.
As shown in Figure 4, described permanent magnet is separately positioned on outside the both sides at amorphous magnetic sheet two ends, and the described direction of arrow is the direction of permanent magnet field, promptly from the N utmost point to the S utmost point.As shown in Figure 9, in this embodiment, the position of permanent magnet is identical with embodiment shown in Figure 4, but magnetic direction is opposite, and the direction of arrow is the direction of permanent magnet field among the figure, promptly from the N utmost point to the S utmost point.
As shown in Figure 5, described permanent magnet is separately positioned on outside the same side at amorphous magnetic sheet two ends, and the described direction of arrow is the direction of permanent magnet field, promptly from the N utmost point to the S utmost point.As shown in figure 10, in this embodiment, the position of permanent magnet is identical with embodiment shown in Figure 5, but magnetic direction is opposite, and the direction of arrow is the direction of permanent magnet field among the figure, promptly from the N utmost point to the S utmost point.
As shown in Figure 6, described permanent magnet is separately positioned on outside the both sides at amorphous magnetic sheet two ends, and the described direction of arrow is the direction of permanent magnet field, promptly from the N utmost point to the S utmost point.As shown in figure 11, in this embodiment, the position of permanent magnet is identical with embodiment shown in Figure 6, but magnetic direction is opposite, and the direction of arrow is the direction of permanent magnet field among the figure, promptly from the N utmost point to the S utmost point.
As shown in Figure 7, described permanent magnet be arranged on directly over the amorphous magnetic sheet or under, the described direction of arrow is the direction of permanent magnet field, promptly from the N utmost point to the S utmost point.As shown in figure 12, in this embodiment, the position of permanent magnet is identical with embodiment shown in Figure 7, but magnetic direction is opposite, and the direction of arrow is the direction of permanent magnet field among the figure, promptly from the N utmost point to the S utmost point.
Described permanent magnet is high remanent magnetism (more than the Br:3000GS) and high-coercive force (more than the Hc:2000oe) material permanent magnet.Because this permanent magnet has high remanent magnetism and high-coercive force, this permanent magnet after magnetizing also is difficult for being reversed in high magnetic field intensity environment very and magnetizes and change original parameter, because the high stability of bias magnetic field also makes the characteristic parameter of the alarm that contains amorphous EAS label stable simultaneously, properties of product are stable.
