Variable capacitance type anti-theft alarm door
The invention discloses a variable capacitance type anti-theft alarm door. The variable capacitance type anti-theft alarm door comprises a door frame and a door plate, the door frame and the door plate comprise an opening and closing side and a hinge side, a fixed electrode sheet and a movable electrode sheet are installed on the end faces, located on the opening and closing side, of the door frame and the door plate respectively, an installation groove is formed in the inner wall of the hinge side of the door frame, a cover plate is arranged on the installation groove in a covering mode, a transformer, an electromagnetic solenoid and a vacuum reversing pipe are installed in the installation groove, and the electromagnetic solenoid is located right above the vacuum reversing pipe. The variable capacitance type anti-theft alarm door is simple and ingenious in structural design, a parallel plate air capacitor is formed by utilizing the movable electrode sheet and the fixed electrode sheet, the distance between the movable electrode plate and the fixed electrode plate and the effective opposite area are changed by opening and closing the door to influence the magnetic force of the electromagnetic solenoid, therefore, the connection state of a metal sliding plug and two conductive electrodes is changed to switch the anti-theft monitoring state and the anti-theft alarm state, the anti-theft reliability is improved, and network support is not needed.
本发明公开了一种变电容式防盗报警门，包括门框和门板，所述门框和门板包括开合侧和铰链侧，所述门框和门板位于开合侧端面上分别安装有定电极片和动电极片，所述门框的铰链侧内壁上开设有安装槽，所述安装槽上盖设有盖板，所述安装槽内分别安装有变压器、电磁螺线管和真空换向管，所述电磁螺线管位于真空换向管的正上方。本发明结构设计简单巧妙，通过利用动电极片和定电极片形成平行板空气电容，通过开关门造成动电极片和定电极片的之间的距离和有效正对面积改变影响电磁螺线圈的磁力，从而改变金属滑塞与两个导电极的连接状态而切换防盗监控和防盗报警状态，增加防盗的可靠性且无需网络支持。
