Automatic Alarm Door Locks and Security Doors

Abstract

The invention relates to the field of anti-theft, in particular to an automatic alarm door lock and an anti-theft door. The automatic alarm door lock includes: a limit switch, an alarm device and a control switch, the limit switch is arranged at the door gap, and when the limit switch moves a certain range, the limit switch sends an electric signal to the alarm device; the control switch and the alarm The device is electrically connected to control the power on and off of the alarm device, and / or the control switch is electrically connected to the limit switch to control the power on and off of the limit switch. In the automatic alarm door lock provided by the present invention, a limit switch is set at the door gap, so that the alarm will only be issued when the door is opened; at the same time, it can also be electrically connected to the alarm device and / or the limit switch through the control The control switch is used to prevent the limit switch from sending electrical signals, or to prevent the alarm device from alarming, which solves the problem that the anti-theft door lock is easy to false alarm and the alarm accuracy is low in the prior art, thereby solving the deficiencies in the prior art .

Description

technical field [0001] The invention relates to the field of anti-theft, in particular to an automatic alarm door lock and an anti-theft door. Background technique [0002] With the improvement of anti-theft technology requirements, a large number of anti-theft doors and anti-theft locks have appeared in production and life. [0003] Traditional anti-theft door locks are divided into two types. The first one adopts mechanical anti-theft means, that is, to strengthen the mechanical structure strength of the door lock, or to strengthen the complexity of the lock cylinder, so that people who use unconventional means to open the door lock need to Consumes a lot of time and energy. But along with the development of technology, it is not enough to achieve effective anti-theft effect by adopting mechanical anti-theft means alone, and its reason is that the door lock can also be opened by cutting or other means of forcibly breaking the door. In order to cope with this situation, a...

Problems solved by technology

[0004] However, the second type of anti-theft door is prone to false alarms.

The main reason is that the sensor cannot effectively detect unconventional unlocking methods. For example, if the induction sensor is installed on the outside of the door, when someone stands outside the door, an alarm will be issued, but in fact, there is no need for an alarm in this case, that is, Alarm accuracy is low
