Door lock prying-resistant device based on gear transmission

Abstract

The invention relates to the technical field of door lock security and protection, and discloses a door lock prying-resistant device based on gear transmission. The device comprises a frame, the left end of the interior of the frame is rotatably connected with a rotating wheel, the left and right ends of the rotating wheel are engaged with first toothed plates, fixed frames are fixedly mounted in the frame and at the upper and lower ends of the rotating wheel, and electrode plates are fixedly mounted in the fixed frames. According to the door lock prying-resistant device based on gear transmission, when a lock is pried, an inserting rod is opened under an abnormal condition, the inserting rod moves leftwards and is matched with second toothed plates to drive moving wheels to rotate, the moving wheels can be matched with guide rods in the rotating process to drive sliding plates to slide leftwards in the fixed frames, and then capacitor plates are driven to get close to the electrode plates, and the electric quantity passing through the capacitor plates is increased accordingly, so that an alarm device in the frame can be started to give out alarm sound, the automatic alarm effect is achieved, and the security awareness is enhanced.
