a fingerprint lock

Abstract

The invention discloses a fingerprint lock, which comprises a lock case panel, a braking device, and a peach clutch for fingerprint identification handle, and is characterized in that: the lock case panel is provided with an arc-shaped pressing bar, and one end of the arc-shaped pressing bar It is connected with the braking device, and the other end is sleeved on the column of the lock housing panel through the reaming hole on it, and the arc part of the arc pressure rod is pressed on the marble in the peach clutch. The brake device is composed of a motor and a slide block, the output shaft of the motor is provided with a torsion spring, the slide block is sleeved on the torsion spring, and one end of the arc-shaped pressing rod is connected with the slide block. Since the motor controls the opening and closing of the peach clutch of the fingerprint recognition handle through the torsion spring to drive the arc-shaped pressure rod, the stability of unlocking the lock is greatly enhanced, and the phenomenon of parts being stuck during the opening process of the lock is reduced. The invention has the characteristics of simple structure, safe and reliable use, and durability.

Description

Technical field: [0001] The invention relates to a lock installed on a door and a safe, in particular to a fingerprint lock. Background technique: [0002] The traditional fingerprint lock has the following disadvantages: there is a kind of fingerprint lock whose fingerprint acquisition and identification controller is not set on the handle, so it needs two operations to open the lock, which causes great inconvenience to the user; The transmission structure is too complicated, so it not only increases the manufacturing cost of the fingerprint lock, but also is prone to failure. In the process of use, its linkage performance is not stable enough. Due to the use of gear transmission, the fingerprint lock is often stuck in the process of opening or closing. phenomenon, so that it affects the normal use of fingerprint locks, and brings great inconvenience to people's daily life. Invention content: [0003] In order to solve the above-mentioned technical problems, the technica...

Problems solved by technology

[0002]The traditional fingerprint lock has the following shortcomings: there is a kind of fingerprint lock whose fingerprint collection and identification controller is not set on the handle, so it needs two operations to open the lock. It causes great inconvenience to users; there are also fingerprint locks because the transmission structure is too complicated, so it not only increases the manufacturing cost of the fingerprint lock, but also is prone to failure. In the process of use, its linkage performance is not stable enough. , the phenomenon that the fingerprint lock is stuck in the process of opening or closing often occurs, which affects the normal use of the fingerprint lock and brings great inconvenience to people's daily life.
