Abstract
The utility model provides an anti-theft alarm device which has simple manufacturing process and low cost, and is compatible with an anti-alarm system of each commercial location. The utility model comprises a shell, a resonance device and a locking device which causes the anti-alarm device to be fixed on merchandise. The utility model is characterized in that the resonance device is composed of a framework, a magnetic core, an inductance coil and a capacitor, wherein, the framework is positioned in the shell; the magnetic core is inserted into the framework; the inductance coil is wound on the framework; the capacitor is in parallel with the inductance coil.
Description
The utility model relates to a kind of burglar alarm, especially for the burglar alarm of commercial locations such as supermarket.
The 58KHZ warning resonance device that uses on the foreign market adopts the metal magnetic sheet to add magnetic patch and is made its production equipment, complex process, production cost height at present.A small amount of this kind of use device is also arranged on the Chinese market, but can only rely on import, therefore improved the cost of commodity greatly, caused unnecessary economic loss to the consumer.
The purpose of this utility model is to provide the burglar alarm that a kind of technology is simple, cost is low and performance can be compatible mutually with external product.
The utility model provides a kind of burglar alarm, can be used for commercial locations such as supermarket, it comprises a shell, one resonance device and one are fixed on locking device on the commodity with this burglar alarm, it is characterized in that described resonance device is made up of the skeleton that is positioned at enclosure interior, the magnetic core that inserts skeleton, the capacitor that is wound in the telefault on the skeleton and is positioned at skeleton one end.
Advantage of the present utility model is that technology is simple, production cost is low, and its resonance frequency may be adjusted to the supermarket guard against theft and alarm system compatible.
Fig. 1 is the sectional view of the burglar alarm of the utility model embodiment;
Fig. 2 is the outside drawing of the burglar alarm of the utility model embodiment.
Describe the structure of the utility model embodiment in detail below in conjunction with accompanying drawing 1.
Burglar alarm as shown in Figure 1 comprises a shell 1, one resonance device and one are fixed on locking device on the commodity with this burglar alarm, described resonance device by the skeleton 4 of the cavity 12 that is positioned at shell 1 inside, the magnetic core 2 that inserts skeleton, telefault 3 and one and the capacitor 5 that is in parallel of this telefault 3 form.Wherein skeleton 4 adopts high strength ABS made; Telefault 3 is made by high strength enamelled wire, and line directly is 0.12mm, and coil turn is 600 circles; Magnetic core adopts φ 4 * 19 soft magnetic bodies rods, and Curie temperature is 200 ℃; Capacitor 5 is the 1000PF multi-layer capacitor of 0805CC4; Fixing effect is played in the space that filler 6 is used to fill up between described resonance device and the shell 1.The resonance device of making thus can produce the resonance frequency of 58KHZ, when this resonance device is in the range of control of the 58KHZ guard against theft and alarm system (EAS SYSTEM) that uses in present most of supermarket, the signal interaction that resonance device can send with warning system and with the wireless system that passes back of resonance signal produces system and reports to the police.Locking device is positioned at the cavity 11 of housing front end, is made up of spring 7, outer steel construction 8, interior steel construction 9 and several steel balls 10, and the upper end of spring 7 contacts with the top of cavity 1, and the lower end contacts with the inner bottom part of interior steel construction 9; Steel ball 10 outside between the bottom outer surface of steel construction 8 bottom interior surfaces and interior steel construction 9, and contact with them; Outer steel construction 8 is placed in outside the interior steel construction 9; Along outer steel construction 8, the vertical axis direction of interior steel construction 9 and shell 1 all has corresponding aperture 8a, 9a, 1a.When using this locking device, the hole that only needs the locking pin to pass target commodity and shell 1 is inserted locking device of the present utility model and this burglar alarm can be fixed on the target commodity firmly.
