A door lock tamper-resistant device based on gear transmission

Abstract

The invention relates to the technical field of door lock security, and discloses a door lock tamper-resistant device based on gear transmission, which includes a frame, and the left end inside the frame is rotatably connected to a rotating wheel, and the left and right ends of the rotating wheel are meshed and connected There is a first tooth plate, a fixed frame is fixedly installed inside the frame and at the upper and lower ends of the rotating wheel, and an electrode plate is fixedly installed inside the fixed frame. The door lock anti-tampering device based on gear transmission, through the situation of picking the lock, the insertion rod is opened under abnormal conditions, the insertion rod moves to the left, and the action of the second tooth plate drives the moving wheel to rotate, and the moving wheel is rotating During the process, the slide plate can be driven to slide to the left inside the fixed frame with the function of the guide rod, and then the capacitor plate is driven close to the electrode plate, and the power passing through the capacitor plate increases accordingly, so that the alarm device inside the frame can be activated to emit an alarm sound, thereby The effect of automatic alarm is achieved, and the security awareness is enhanced.

Description

Technical field [0001] The present invention relates to the technical field of security locks, in particular to a smart door lock device gear based on tamper.
