DEVICE FOR MONITORING STATES OF DOOR AND WINDOW

WIPO Patent Application WO/2017/101698

A1

Provided is a device for monitoring states of a door and a window. The device comprises a housing (3) provided with a groove (2). A signal sensing mechanism in the housing (3) comprises a first fixed sensing sheet (4) and a second fixed sensing sheet (9). The upper end and the lower end of an elastic connection member (7) in the groove (2) are respectively fixed on a first movable sensing sheet (6) and the second fixed sensing sheet (9). An insulation connection rod (1) is mounted on the first movable sensing sheet (6). The upper part of the connection rod (1) protrudes over the first fixed sensing sheet (4). A movable sensing sheet (8) is mounted on the lower end of the connection rod (1). A distance between the second movable sensing sheet (8) and the second fixed sensing sheet (9) is equal to a distance formed when the upper part of the connection rod (1) protrudes over the first fixed sensing sheet (4). The first fixed sensing sheet (4), the second fixed sensing sheet (9), the first movable sensing sheet (6) and the second movable sensing sheet (8) are all connected to a signal receiver (10). The device has a simple structure, can be used for monitoring a door and window system having higher air tightness and temperature keeping performance, can implement the monitoring in real time, and can improve the safety of a door and a window in use.
