Clutch driving device of electronic lock

Abstract

The invention discloses a clutch driving device of an electronic lock. The clutch driving device comprises a cam, wherein the cam is connected with a push rod and used for driving the push rod to vertically move; the push rod is connected with a lifting lever through a tensile spring, the lifting lever is arranged on a fixed rotary shaft and rotates around it; the lifting lever is moved around the rotary shaft by the push rod so as to pop out or withdraw the push plate connected with the lifting lever. The clutch driving device is simple in structure; through the rotation of the cam, the vertical movement of the push rod is controlled, and the push rod is further connected with the lifting lever through the tensile spring; the lifting lever is moved around the rotary shaft by the push rod so as to pop out or withdraw the push plate connected with the lifting lever, thus the clutch is realized; besides, the action of the tensile spring cannot damage the cam when the external force pushes the push plate to withdraw.

Description

technical field [0001] The invention relates to a lock, in particular to a clutch driving device for an electronic lock. Background technique [0002] In daily life, it is often seen that electric control locks such as code locks and fingerprint locks are used in various occasions, especially public places such as hotels and shopping malls, due to the convenience of not carrying keys and the high security of passwords and fingerprints , deeply loved by the people. [0003] The traditional electric lock control panel is equipped with a handle, an electric controller with a password button or a fingerprint verifier, a lock body and a clutch assembly, wherein the clutch assembly includes a lock body linkage shaft linked with the lock body and a handle Linked handle linkage shaft, the lock body linkage shaft is provided with a rotating chamber for the handle linkage shaft to be inserted and rotated coaxially, the wall of the rotating chamber is provided with a clutch lever that...

Problems solved by technology

[0003] The traditional electric lock control panel is equipped with a handle, an electric controller with a password button or a fingerprint verifier, a lock body and a clutch assembly, wherein the clutch assembly includes a lock body linkage shaft linked with the lock body and a handle Linked handle linkage shaft, the lock body linkage shaft is provided with a rotating chamber for the handle linkage shaft to be inserted and rotated coaxially, the wall of the rotating chamber is provided with a clutch lever that can automatically reset to the outside, and the handle linkage shaft is arranged radially There is a clutch groove matched with the clutch lever. One end of the clutch lever faces the inner side of the rotating chamber as the mating end with the clutch groove, and the other end extends out of the rotating chamber as the control end. When the correct password or fingerprint is input, the electric controller pushes the clutch lever The control end of the control end makes the matching end extend into the clutch groove to form the linkage between the handle linkage shaft and the lock body linkage shaft. The handle controls the lock body to realize the purpose of opening the door leaf, and when there is no or wrong password or fingerprint input, the electric controller will not Action, the mating end of the clutch lever is far away from the clutch groove, and the handle can't control the lock body to open the door when the handle is idling

After twisting the handle for a long time, the position of the clutch groove of the handle linkage shaft and the mating end of the clutch lever will be slightly shifted, so that the electric controller cannot push the clutch lever, that is, the handle cannot pass through the lock body linkage axis and the handle linkage axis. The linkage control handle greatly affects the normal use
