Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution:

a reversing mechanism for a smart lock, comprising:

the outdoor panel 1 is fixedly connected with the indoor panel through a fixing screw rod, and an unlocking part 2 is embedded on the outdoor panel 1;

the reversing part 3 is positioned on the back surface of the outdoor panel 1, and is fixedly connected with the inner wall of the outdoor panel 1;

the outdoor handle 4, outdoor handle 4 passes through switching-over portion 3 and outdoor panel 1 fixed connection, but outdoor handle 4 and switching-over portion 3 split type fixed connection.

Because the function of intelligence lock is more and more comprehensive, outdoor handle 4 need not undertake the function of unblanking basically, only is used for assisting the effect of opening or closing the door, consequently, outdoor handle 4 need not carry out the transmission with the lock body and is connected to realize rotating and unblank, and for the convenience of outdoor handle 4's switching-over, outdoor handle 4 also can not form with outdoor panel 1 integrated into one piece, constitutes overall structure.

Therefore, adopt outdoor handle 4 to pass through switching-over portion 3 and outdoor panel 1 fixed connection in this scheme, but and

outdoor handle

4 and 3 split fixed connection of switching-over portion to realize the function of outdoor handle 4 switching-over, when needs switching-over, only need with

outdoor handle

4 and 3 completion after the split of switching-over portion change can, the operation is more simple and convenient.
