Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Embodiment 1:
With reference to accompanying drawing: present embodiment comprises shell 3, by alarm chip 1, hand switch 2, loudspeaker 7, the electronic alarm that power supply 8 is formed, other is provided with an inductor, described inductor comprises a microswitch 4 that is installed on the shell and links to each other with electronic alarm, one can be moved and the roller 5 that rolls with door and window, roller is provided with 1 pentalpha gear 6 that links with roller coaxial following roller, star angle on the pentalpha gear does not contact with microswitch when non-alarm condition, when door and window moves, the pentalpha gear is rotation simultaneously also, and the star angle on the gear can contact and trigger alarm work with microswitch.
Can fix or fix with the Luo silk during installation with the adhesive tape stickup.The installation site can be on the downside frame of a fan aluminium/plastic door and window, and promptly the A position among the figure makes roller 5 contact with windowsill, can report to the police when move at this side window family; Also can be installed in the intersection of Yishanmen window and another fan door and window inboard, i.e. B place among the figure, roller contacts with the window on the right, mobile at this moment about the window of two sides all can report to the police.The installation site should guarantee window flexibly opening and closing to any position.Time spent not, with power-off, at this moment people can the free switch window; As power supply opening with electronic alarm, can enter the warning stand-by state, also can be coupled in the warning system by wired or wireless device.When theft criminal molecule passes through in the door and window inlet chamber, as long as remove this fan aluminium/plastic door and window, roller is promptly along with rolling together, and the gear of the pentalpha of drive and roller interlock rotates, tooth angle on the gear can touch microswitch at this moment, cause electronic alarm and report to the police, and by megaphone 7 amplification that amplifies, make the late into the night hypnopompic people also can hear alarm sound; Also can be coupled in the warning system by wired or wireless device, directly the operator on duty reports to the police in public security organ or apartment.
