Structure with mechanical door lock upgraded into intelligent door lock

Abstract

The invention discloses an intelligent door lock and provides a structure with a mechanical door lock upgraded into an intelligent door lock. The structure is simple, is obtained by refitting an existing mechanical door lock, and is low in refitting cost, safe and reliable. The technical problems that in the prior art, cost is high when the mechanical door lock is upgraded into the intelligent door lock, difficulty is large, and the intelligent door lock cannot be applied and popularized are solved. The structure comprises a mechanical lock cylinder and a key inserted in a lock hole of the lock cylinder in a matched manner. A linkage device and an electronic inductor are arranged on the outer end face of the key. The linkage device is provided with a linkage rod capable of sliding in the radial direction. An annular shell is rotationally connected to the outer side end of the portion, corresponding to the linkage device, of the lock cylinder in a matched manner. The electronic inductor is close to an outer port of the annular shell and controls the radial sliding of the linkage rod through a controller. A plurality of strip-shaped axial locking grooves are formed in the portion, corresponding to the outer side end of the linkage rod, of the inner wall face of the annular shell. When the linkage rod slides outwards in the radial direction, the linkage rod is clamped in the axial locking grooves in a matched manner.

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.
