Intelligent alarm device of sliding doors and windows

Abstract

The invention relates to an intelligent alarm device of sliding doors and windows, belonging to the field of anti-theft devices. An inner cylinder (4) capable of axially sliding in a limited mode is mounted in a cylindrical shell (1) which is provided with a main rotating shaft (7), a roller (9) and a pinion (10) are mounted on the main rotating shaft (7), and a large gear (15) mounted on an auxiliary rotating shaft (14) is engaged with the pinion (10). When one part of the roller (9), which is exposed out of the cylindrical shell (1), rotates under the displacement action of the doors and the windows, a microswitch (17) which is mounted at the outer side of the a left soleplate (5) of the inner cylinder (4) is poked by the large gear (15) through transmission to switch on a circuit, a buzzer (20) alarms in delay, a spring (6) and a double-contact-type travel switch are mounted between the left soleplate (5) and a cover plate (3), and the travel switch acts and alarms when the surfaces of the doors and the windows are deformed internally and externally by force. The invention can alarm if the doors or the windows move, is flexible, reliable and convenient to mount and adjust by being mounted on an object, and has strong integrity and favorable invisibility without influencing the appearances of the doors or the windows.

Description

technical field [0001] The invention belongs to the field of anti-theft devices and relates to an intelligent alarm device for push-pull doors and windows. Background technique [0002] In the prior art, there are generally two types of anti-theft alarm devices for push-pull doors and windows, one is the mechanical travel switch control type, and the other is the electronic switch (inductive device, infrared control head or pressure touch switch) control type. Microelectronic circuit, such as the technical scheme disclosed by the application number 02113286. On two objects that are closely related to the opening or closing of a door or window, at least one of the objects should be a door or window. , Right push-pull displacement, and must be opened to a certain extent, the switch can work and alarm, so when the door or window is displaced in a direction other than the established one, it cannot act as an alarm. Open to a certain degree and just can report to the police oth...

Problems solved by technology

[0002] In the prior art, there are generally two types of anti-theft alarm devices for push-pull doors and windows, one is the mechanical travel switch control type, and the other is the electronic switch (inductive device, infrared control head or pressure touch switch) control type. Microelectronic circuit, such as the technical scheme disclosed by the application number 02113286. On two objects that are closely related to the opening or closing of a door or window, at least one of the objects should be a door or window. , Right push-pull displacement, and must be opened to a certain extent, the switch can work and alarm, so when the door or window is displaced in a direction other than the established one, it cannot act as an alarm. Open to a certain degree to alarm and other accidents after "opening" are prone to occur. 3. It is inconvenient to install and adjust, lacks concealment, and affects the appearance of doors or windows.
