Automatic alarm anti-theft glass

Abstract

The invention discloses an automatic alarming burglar-proof glazing that is made up of glazing, and conductive metal line. The metal line is formed by the metal powder adhering on the glazing, and connects to alarming system. The invention has simple structure, and easy to be machined. When the glazing broken, the metal line would be broken and alarm to achieve burglar-proof effect.

Description

technical field [0001] The invention relates to the technical field of anti-theft, in particular to anti-theft glass with automatic alarm function. Background technique [0002] In the prior art, there is a kind of "anti-theft glass with automatic alarm and bulletproof" as disclosed in ZL96237242.0, as shown in Figure 1 and 1A, which is composed of ordinary glass 1' and metal wire 2', and the metal wire 2' is pressed by polyester adhesive. The design density is fixed on the glass 1', and the polyester film is pasted on the metal wire 2' with polyester adhesive, compacted without air bubbles, and the metal wire 2' is connected with the alarm system in series to make an automatic alarm anti-theft glass. When the glass 1' was broken, the wire 2' was pulled off, the power supply was cut off, and the alarm system was activated.

Problems solved by technology

[0003] Careful analysis of the above-mentioned anti-theft glass with automatic alarm, it is not difficult to find that there are still shortcomings: because the metal wire 2' is arranged on the glass 1', the metal wire 2' itself has a certain flexibility, so when the glass 1' is damaged However, the metal wire 2' is often connected between the broken glass 1' without breaking, and the phenomenon of "broken wire connection" occurs, and the automatic alarm effect cannot be achieved; moreover, the metal wire 2' has a certain diameter, and the layout is relatively inconvenient, not only It needs to be adhered with polyester adhesive, and also needs to be covered with polyester film to prevent the metal wire 2' from partially falling off, and the polyester film itself has a certain degree of flexibility. With the protection of the polyester film, the broken glass 1' fragments and metal The wire 2' is still pasted on the polyester film together, the metal wire 2' cannot be disconnected, and the effect of automatic alarm cannot be achieved

In short, the existing automatic alarm and anti-theft glass has a complex structure and poor alarm effect, so there is indeed a need for improvement
