The invention discloses a multi-point-control pneumatic door / window anti-theft alarm triggering device and relates to an anti-theft alarm triggering device. The multi-point-control pneumatic door / window anti-theft alarm triggering device comprises a flexible tube, a hard tube, a push rod, an elastic device, an adjustment nut and a pricking needle, wherein the flexible tube is installed on the bottom of an inner hole of the hard tube, one end of the flexible tube is sealed, the other end of the flexible tube is connected with an anti-theft alarm microswitch located indoors, and the flexible tube is filled with air so that the flexible tube can be expanded; a long notch is formed in the hard tube; one end of the push rod is connected to the door / window, the other end of the push rod abuts against the elastic device, one end of the elastic device is fixed, and the other end of the elastic device is movable and can rotate around the fixed end of the elastic device; the movable end of the elastic device is connected with the pricking needle through the adjustment nut, and the flexible tube in the hard tube is pricked through the pricking needle after the pricking needle penetrates through the long notch during triggering. According to the multi-point-control pneumatic door / window anti-theft alarm triggering device, an external power supply is not needed when the device is installed on site, and the device has the advantages of being small in size and exquisite, capable of being installed in a hidden mode, simple in structure and low in cost; the device can be safely used in places where electric-control or magnetic-control alarms can not be installed conveniently as well as outdoor temporary places where no electricity can be supplied, and the application range is wide.
Description
technical field [0001] The invention relates to an anti-theft alarm trigger device, in particular to a multi-point control pneumatic door and window anti-theft alarm trigger device. Background technique [0002] At present, most anti-theft alarm devices need electric control or magnetic control. These devices cannot work when the power is off, which makes some temporary places or open places lack alarm devices. It is also not safe to use. In addition, the trigger of the current anti-theft alarm device is relatively easy to alarm the thief, and its infrared probe is installed outdoors and can be shielded by experienced thieves. Contents of the invention [0003] The technical problem to be solved by the present invention is: to provide a multi-point control pneumatic door and window anti-theft alarm trigger device that does not need an external power supply on the installation site, so as to solve the problems in the prior art that the above-mentioned power failure cannot ...
