Abstract
The utility model relates to an antitheft rolling door, in particular to a magnetic induction alarm antitheft rolling door. The magnetic induction alarm antitheft rolling door comprises a doorframe, a rolling door plate and an antitheft alarm. The antitheft alarm is provided with a magnetic induction switch. The magnetic induction switch is electrically connected with the antitheft alarm by a lead wire. The magnetic induction switch is arranged at the lower end of any one side edge of the doorframe. In the closed state, the rolling door plate corresponding to the magnetic induction switch is provided with a magnet. After the antitheft rolling door is closed, the magnetic induction switch is induced by the magnet to be changed into the closed state from the normally-open state and the antitheft alarm is in the monitoring work. When the antitheft rolling door is opened by a person who is not the master, the distance between the magnetic induction switch and the magnet is lengthened, the magnetic induction switch loses excitation to be changed into the off state from the closed state and a switch-off trigger alarm of the magnetic induction switch gives an alarm. The magnetic induction alarm antitheft rolling door has the advantages that the structure is simple; the magnetic induction alarm antitheft rolling door is convenient to install; and the tripping fault is difficult to generate.
Description
Technical field
The utility model relates to a kind of antitheft rolling door, specifically is a kind of magnetic induction alarming anti-theft rolling door.
Background technology
Magnetic induction alarming anti-theft rolling door mainly is made of doorframe, rolling door plate and magnetic induction alarm, and the magnetic induction alarm is provided with magnetic induction switch.Existing magnetic induction alarming anti-theft rolling door, its magnetic induction switch is arranged on the lower end of rolling door plate, in the doorframe bottom of magnetic induction switch correspondence magnet is set, and when the robber pried open the rolling door plate, magnetic induction switch left magnet, magnetic induction switch action triggers alarm equipment alarm.Above-described magnetic induction alarming anti-theft rolling door, because magnetic induction switch is arranged on the lower end of rolling door plate, and then is connected with alarm by long lead, its shortcoming is: circuit is long, and frequent rolling of rolling door plate and expansion, breaks lead easily, produces fault; Secondly,, need on the floor, perforate install magnet during installation because magnet is arranged on the bottom of doorframe, time-consuming, bothersome, and influence attractive in appearance.
Summary of the invention
The purpose of this utility model is the improvement to above-mentioned magnetic induction alarming anti-theft rolling door, provides a kind of simple in structure, easy for installation, is difficult for producing the magnetic induction alarming anti-theft rolling door of disconnection fault.
The utility model, comprise doorframe, rolling door plate and burglar alarm, burglar alarm is provided with magnetic induction switch, magnetic induction switch is electrically connected with burglar alarm by lead, magnetic induction switch is arranged on the lower end of arbitrary side of doorframe, down, the rolling door plate place corresponding with magnetic induction switch is provided with magnet in off position.
Its operating principle is: after antitheft rolling door is closed, magnetic induction switch is responded to by magnet, become closure state by often opening, burglar alarm is in the monitoring work, when the non-owner of antitheft rolling door opens, magnetic induction switch and magnet distance are drawn back, and the magnetic induction switch loss of excitation becomes off-state by closure state, the break trigger alarm equipment alarm of magnetic induction switch.
The utility model has advantages such as simple in structure, easy for installation, difficult generation disconnection fault.
