Engagement and disengagement module of intelligent lock

Abstract

The invention relates to an engagement and disengagement module of an intelligent lock. The engagement and disengagement module comprises a shell, a handle head, an engagement and disengagement rotating block, an engagement and disengagement sleeve, an engagement and disengagement pin and an electric push rod used for driving the engagement and disengagement pin. The handle head and a center holeof the engagement and disengagement sleeve are in running fit. A convex block is arranged on the periphery of the position, corresponding to the center hole, of the handle head. A reversing screw of the convex block is provided with an eccentric connecting hole. Holes of the engagement and disengagement sleeve are through holes. The reversing screw penetrates through the corresponding through holeto be connected with the eccentric connecting hole. A reset mechanism is arranged between the engagement and disengagement rotating block and the engagement and disengagement sleeve. The reversing screw of the engagement and disengagement module can be used for fixing the handle head besides limiting the rotating direction of the engagement and disengagement rotating block; and the reversing screw and the handle head are fixed eccentrically, a handle does not need to be demounted during reversing so as to avoid the situation that accumulated gaps are generated after the handle is demounted and mounted, and consequently normal work of the engagement and disengagement module is influenced.

Description

technical field [0001] The invention relates to an intelligent lock, in particular to an intelligent lock clutch module. Background technique [0002] The characteristics of the traditional clutch module of the smart lock: the handle needs to be loosened to change the direction of the handle, and then re-tighten the screw after turning the direction. This method requires high precision of the installation and parts, and the handle screw may loosen after the change of direction; There is no reset mechanism between the rotary block and the clutch sleeve, and the clutch rotary block is reset by the rear handle. When there is a cumulative gap in the fit, it is easy to cause the clutch pin to fail to insert into the clutch rotary block, resulting in idling when the door is opened. Contents of the invention [0003] The object of the present invention is to provide a smart lock clutch module with simple and reasonable structure, no need to disassemble the handle for reversing, a...
