Abstract

The invention discloses a cam mechanism for a fingerprint lock, and relates to the field of anti-theft locks. The mechanism is mainly composed of a cam shaft, a moment limiter, a driven ring, a cam ring, a thumbwheel, a main clutch and a subsidiary clutch. The cam mechanism is located in the lock body of the fingerprint lock, one end is connected to a handle, the other end is connected to drive parts of a lock plunger and a spring bolt and used for transmitting, controlling or stopping rotary motion of the handle, fingerprint identification unlocking, key inserting key unlocking and locking operation are all achieved by the same handle, and the handle can idle when strong wrenched. As an alternative solution of the prior art, the subsidiary clutch of the cam mechanism is arranged between the driven ring and the cam ring, and the way to drive the subsidiary clutch through a key is abandoned. The main clutch is still arranged between the thumbwheel and the driven ring, a motor can meanwhile drive two clutches to close, the structure is more compact, stability and safety are more outstanding, and original permeability of a lock core is restored.

Description

technical field [0001] The invention relates to the field of anti-theft locks, in particular to a cam mechanism of a fingerprint lock. Background technique [0002] The structure of the fingerprint lock generally includes the outer panel of the lock, the inner panel of the lock, the handle, the lock body, the spare mechanical key, the fingerprint identification system or the password identification system, and the motor clutch or electromagnetic clutch under its control. [0003] Under normal circumstances, the fingerprint lock completes the locking action by rotating the handle in the opposite direction (that is, lifting the handle), or automatically locks when the door is closed; when the fingerprint or password is used to unlock the lock, after the fingerprint identification or password identification is correct, the motor clutch Or the electromagnetic clutch is closed, and the unlocking is completed by rotating the handle in the positive direction. When the fingerprint ...
