Multipoint controlled pneumatic door and window burglarproof alarm trigger apparatus

A multipoint controlled pneumatic door and window burglarproof alarm triggering apparatus relates to a burglarproof alarm trigger apparatus and includes a flexible pipe, a hard pipe, a push rod, an elastic device, a regulating nut, and a pricker. The flexible pipe is disposed at the bottom of an inner hole of the hard pipe. One end of the flexible pipe is enclosed while the other end of the flexible pipe is connected with a burglarproof alarm microswitch positioned indoors. The flexible pipe is filled with air and expands. A long groove opening is disposed in the hard pipe. One end of the push rod is connected with a door and window while the other end pushes against the elastic device. One end of the elastic device is a fixed end while the other end is a movable end capable of rotating around the fixed end. The movable end is connected with the pricker through the regulating nut. When the burglarproof alarm trigger apparatus is triggered, the pricker pierces the long groove opening of the hard pipe in the flexible pipe in the hard pipe. No external power supply is needed on an installation scene. The multipoint controlled pneumatic door and window burglarproof alarm trigger apparatus is characterized by small size, concealed installation, simple structure and low cost, is safe to use in places where an electrically controlled or magnetically controlled alarm cannot be conveniently installed, can be used in temporary outdoor places where no power supply is provided, and has a wide application range.
