Embodiment Construction
[0010] The present invention will be further described in detail below in conjunction with the examples. It should be understood that these examples are only for illustrating the present invention and are not intended to limit the scope of the present invention.
[0011] Such as figure 1 As shown, a glass break detector includes a first reed 1, a second reed 2, a first electrode 3, a second electrode 4, a housing base 5, and a housing cover 6. The first reed 1 is horizontally The cross section is in a curved shape, and the curved part can effectively absorb the frequency generated by knocking on the glass or slight vibration, avoiding false alarms and effectively improving the accuracy of the alarm. The first electrode 3 is arranged on the first reed 1 At the right end, the second electrode 4 is located at the right end of the second reed 2, and the positioning screw 7 fixes the positions of the first reed 1 and the second reed 2, so that the left ends of the first reed 1 and ...

The invention discloses a glass break detector. The glass break detector comprises a first spring leaf, a second spring leaf, a first electrode, a second electrode, a casing bracket and a round casing cover, wherein the cross section of the first spring leaf is bent; the first electrode is arranged at the right end of the first spring leaf, and the second electrode is arranged at the right end of the second spring leaf; a positioning screw is used for fixing the positions of the first spring leaf and the second spring leaf to enable that the first spring leaf and the second spring leaf are insulated; the first electrode and the second electrode are contacted; and the positioning screw is fixedly connected with the casing bracket, and the round casing cover is arranged on the casing bracket. According to the invention, the cross section of the first spring leaf is bent, thus the first spring leaf can absorb vibration generated by low frequency, unnecessary wrong alarm can be avoided, and alarm accuracy is improved. The glass break detector is simple in structure, low in production cost, wide in adaptability and suitable for industrial production.
Description
technical field [0001] The invention relates to an anti-theft device, in particular to a glass breaking detector. Background technique [0002] With the advancement of science and technology and the continuous improvement of productivity levels, people's material wealth is becoming more and more abundant and more valuable. The necessary anti-theft device has become an indispensable equipment to ensure the safety of people's lives and property. However, the anti-theft devices or shapes on the market are too large, which is not conducive to the appearance of furniture or has a high false alarm rate, which is easy to cause troubles in people's daily life and is not conducive to the long-term development of the security industry. The anti-theft device with low reporting rate is the primary problem to be solved in the security industry. Contents of the invention [0003] Purpose of the invention: The purpose of the invention is to overcome the deficiencies of the prior art an...
