Abstract
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
The present invention relates to a kind of anti-theft device, especially a kind of glass breaking detector.
Background technology
Along with scientific and technical progress, the improving constantly of the level of the productive forces, people's material wealth is also more and more abundanter, more and more valuable, and necessary anti-theft device becomes the requisite equipment of people's security of the lives and property that ensures.But anti-theft device in the market or shape are excessive, attractive in appearance or the rate of false alarm that is unfavorable for furniture is high, easily daily life is caused to puzzlement, be unfavorable for the long term growth of security protection industry, therefore, providing the small and exquisite anti-theft device attractive in appearance and that rate of false alarm is low of a kind of profile is the primary problem solving of security protection industry.
Summary of the invention
Goal of the invention: the object of the invention is in order to overcome the deficiencies in the prior art, provide a kind of profile small and exquisite attractive in appearance and rate of false alarm is low, the glass breaking detector that production cost is few.
Technical scheme: in order to solve the problems of the technologies described above, a kind of glass breaking detector of the present invention, comprise the first reed, the second reed, the first electrode, the second electrode, outer casing base, casing cover, the first described reed xsect is bending shape, the first described electrode is located at the right-hand member of the first reed, the second described electrode is located at the right-hand member of the second reed, set screw is fixed the first reed and the second reed position, make the first reed, the second reed left end insulation, the first electrode, the second electrode contact, described set screw is fixedly connected with outer casing base, described casing cover is located on outer casing base, the first described reed, the second reed is connected to alarming horm by lead-in wire.
Described set screw is insulator.
Described the first reed, the second reed are conductive metallic material.
Described the first reed, the second reed are connected with alarming horm by the first lead-in wire, the second lead-in wire.
Beneficial effect: compared with prior art, advantage of the present invention is: the present invention, by the first reed xsect is arranged to bending shape, can absorb the vibrations that low frequency produces, and avoids unnecessary false alarm, improves alarm accuracy; The present invention is simple in structure, only can effectively realize alarm by two reeds and electrode with being just connected of alarming horm, low production cost, and wide adaptability, is suitable for industrialization and produces.
