Automatic warning door lock and antitheft door

Abstract

The invention relates to the field of antitheft, in particular to an automatic warning door lock and an antitheft door. The automatic warning door lock comprises a position limiting switch, a warning device and a control switch, wherein the position limiting switch is arranged outside a door seam, when the position limiting switch moves a certain amplitude, the position limiting switch sends out electric signals to the warning device, the control switch is electrically connected with the warning device so that the on-off state of the warning device can be controlled, and / or the control switch is electrically connected with the position limiting switch for controlling the on-off state of the position limiting switch. The automatic warning door lock provided by the invention has the advantages that the position limiting switch is arranged at the door seam part, so the warning can only be carried out when the door is unlocked, meanwhile, the position limiting switch can also be prevented from sending electric signals through controlling the control switch electrically connected with the warning device and / or the position limiting switch, or the warning device is prevented from warning, and the problems of easy false warning and low warning accuracy of the antitheft door lock in the prior art are solved, so the defects in the prior art are overcome.

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
