Door lock provided with double lock cylinders

Abstract

The invention aims at providing a door lock provided with double lock cylinders. The door lock comprises a mechanical lock body and an electronic control lock body which are arranged on a door frame, wherein the mechanical lock body is provided with a lock tongue and a buckling box; the buckling box is provided with a proximity sensor; the electronic control lock body is connected with an electronic control lock body driving module; the door lock provided with the double lock cylinders also comprises a fingerprint detection module, a fingerprint compartment, an indoor switch of the electronic control lock body, a control circuit unit, a data memory module, a key input module and a display module. The door lock provided with the double lock cylinders is capable of effectively avoiding the potential safety hazard caused by the single protection of a mechanical lock cylinder and preventing a fingerprint identification module from being exposed outside for a long time and contaminated by impurities, so that the use stability is guaranteed, and the fingerprint identification module is prevented from being damaged maliciously; furthermore, if a fingerprint control system is damaged, the failure of an electronic system of a door control system can be realized by a set verified mobile terminal through an emergency mechanism, and the mechanical lock cylinder is only used for guaranteeing emergency usage, so that a user can conveniently meet an emergency.

Description
