A structure for upgrading a mechanical door lock to an intelligent door lock

Abstract

The invention discloses an intelligent door lock, which provides a simple structure, which is modified on the basis of the original mechanical door lock, and the transformation cost is low, and the safe and reliable mechanical door lock is upgraded to an intelligent door lock structure, which solves the problem There are technical problems such as the high cost and difficulty of upgrading the mechanical door lock to the smart door lock, which prevents the popularization and application of the smart door lock. It includes the lock cylinder of the mechanical lock and the lock that is mated and plugged into the lock cylinder The key in the hole is provided with a linkage device and an electronic sensor on the outer end surface of the key. The linkage device is provided with a linkage rod that can slide in the radial direction, and the outer end of the lock cylinder corresponding to the linkage device is connected to each other by rotation. An annular shell, the electronic sensor is close to the outer port of the annular shell and controls the radial sliding of the linkage rod through the controller. There are several axial locking grooves on the inner wall of the annular shell corresponding to the outer end of the linkage rod. The interfitting clamps in the axial locking groove when sliding radially outward.

Description

technical field [0001] The invention relates to an intelligent door lock, in particular to a structure in which the original mechanical door lock is transformed on the basis of the original mechanical door lock, the cost of transformation is low, and the safe and reliable mechanical door lock is upgraded to an intelligent door lock. Background technique [0002] Due to its low price, mechanical door locks are widely used. However, due to their low security and inconvenient carrying and replacement of keys, they are increasingly replaced by smart door locks. Smart door locks have high security. Locks and keys (IC Cards, fingerprints, passwords, radio waves from remote controls, etc.) can form a many-to-many relationship, and the keys are easy to carry and easy to manage. When replacing a smart door lock, the original lock hole on the door needs to be reprocessed, or even the entire door needs to be replaced. Therefore, it is costly and difficult to upgrade a mechanical door l...

AI Technical Summary

Problems solved by technology

[0003] The present invention mainly provides a structure that is simple in structure, is transformed on the basis of the original mechanical door lock, and the cost of transformation is low. When the door lock is upgraded to a smart door lock, the cost is high and the difficulty is great, so that the smart door lock cannot be popularized and applied.
