Description

Electronic lock core clutch device

Technical Field

The utility model relates to a house field, specifically speaking relate to an electronic lock core clutch.

Background

At present, with the development of social life and technology, hardware related to intelligent home is developed like bamboo shoots in spring after rain. The electronic lock is convenient to use because a key is not required to be carried, and the pain of many people in daily life is solved, so that the electronic lock is rapidly popularized. At present, most electronic locks are produced and sold in an integral lock mode, so that the cost is high, the shape and the size of the electronic locks are greatly different from those of the existing locks, and the installation difficulty is high. This requires only a professional to install it, greatly increasing the threshold for use of the electronic lock. Compared with the electronic lock in the form of a whole lock, the electronic lock cylinder has low cost and is installed in a manner similar to a mechanical lock cylinder, and thus has gained wide attention.

The fingerprint lock is an intelligent lock, and is a perfect crystal of a computer information technology, an electronic technology, a mechanical technology and a modern pentrax process, the fingerprint refers to uneven lines on the front skin of the tail end of a finger, although the fingerprint is only a small part of the skin of a human body, the fingerprint contains a large amount of information, the lines are different on patterns, break points and intersection points, the fingerprint is called as 'characteristics' in information processing, and the characteristics have uniqueness and permanence, so that a person can correspond to the fingerprint of the person, the real identity of the person can be verified by comparing the fingerprint characteristics of the person with the fingerprint characteristics stored in advance, and the fingerprint authentication has the characteristics of convenience, rapidness and accuracy.
