Abstract
The invention discloses a door and window anti-theft alarm which comprises a voltage transformation and stabilization device, a voice alarm device, magnetic contact blocks, spring contact blocks and a switch. The voltage transformation and stabilization device can be replaced by a cell, one output end of the voltage transformation and stabilization device is electrically connected with the voice alarm via the switch, the other output end of the voltage transformation and stabilization device is electrically connected with the magnetic contact blocks, the spring contact blocks are electrically connected with the voice alarm device, each spring contact block is composed of a spring, a conductive contact block and a push rod, the conductive contact block is fixedly connected with the corresponding spring, the push rod is fixedly connected with the corresponding conductive contact block, and the conductive contact block is electrically connected with the voice alarm device. The anti-theft alarm is simple in structure, low in production cost, convenient to use, and good in antitheft alarming effect, and can be widely applied to prevent indoor and case theft and the like.
Description
Technical field
The present invention relates to a kind of door window antitheft alarm.
Background technology
The force open the door event of pivot frame burglary of current robber happens occasionally, and existing burglar alarm general structure is more complicated, and production cost is higher, and it is convenient not to use.
Summary of the invention
For solving above-mentioned existing shortcoming, fundamental purpose of the present invention is the door window antitheft alarm providing a kind of practicality, and structure is simple, and production cost is low, easy to use.Anti-theft alarm result is good.Can be widely used in indoor antitheft, case and bag are antitheft.
For reaching above-described object, following technical scheme taked by a kind of door window antitheft alarm of the present invention:
A kind of door window antitheft alarm, comprise transformation voltage stabilizer, phonetic alarm, magnetic contact block, spring contact block and switch, described transformation voltage stabilizer can be replaced by battery, an output terminal of described transformation voltage stabilizer is electrically connected with described phonetic alarm by described switch, another output terminal is electrically connected with described magnetic contact block, described spring contact block is electrically connected with phonetic alarm, described spring contact block is by spring, conduction contact block and push rod composition, described conduction contact block and spring are fixedly linked, described push rod is fixedly linked with conduction contact block, described conduction contact block is electrically connected with described phonetic alarm.
Adopt the present invention of as above technical scheme, there is following beneficial effect:
Structure of the present invention is simple, and production cost is low, easy to use.Anti-theft alarm result is good.Can be widely used in indoor antitheft, case and bag are antitheft.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
In order to further illustrate the present invention, be described further below in conjunction with accompanying drawing:
As shown in Figure 1, a kind of door window antitheft alarm of the present invention, spring contact block is made up of spring 5, conduction contact block 6 and push rod 7, and conduction contact block 6 is fixedly linked with spring 5, and push rod 7 is fixedly linked with conduction contact block 6, and conduction contact block 6 is electrically connected with phonetic alarm 2.Be electrically connected with commercially available phonetic alarm 2 by switch 4 by an output terminal of commercially available transformation voltage stabilizer 1, another output terminal is electrically connected with magnetic contact block 3.When installing and using, be arranged on door and window or sash by magnetic contact block 3 and spring contact block, when door and window is closed, the push rod 7 of spring contact block is withstood on Compress Spring 5 on door and window or sash, conduction contact block 6 and magnetic contact block 3 are disengaged, and phonetic alarm 2 is in power-off closed condition; When door and window is opened by robber, the push rod 7 of spring contact block loses top power, and Compress Spring 5 resets, and conduction contact block 6 is contacted with magnetic contact block 3, and phonetic alarm 2 is in energising duty, sends phonetic alarm sound.The conduction contact block electrical connection of each door and window, the magnetic contact block 3 of each door and window is electrically connected, magnetic contact block 3 is conducive to utilizing magnetic attraction to contact more excellent with conduction contact block 6.Transformation voltage stabilizer is that plug-type is inserted in supply socket, and switch 4 controls the duty of alarm for user.
