It can be used after being packaged according to the existing packaging process and technology of the electromechanical module of the smart lock.

when using it:

Before the lock is installed and used, forcefully rotate the door handle 16 in a certain direction in the desired direction. If the rotation in this direction is blocked, the reason for the blocking is the interaction between the locking table 31 and the locking head 41 , or the limit table 34 Interacting with the housing of the locking spring pin 4, it is only necessary to rotate the door handle 16 in the opposite direction, and then the door handle 16 can be rotated in the desired direction. Because it is before installation, the door handle 16 is rotated in the predetermined direction at this time, and the handle reset wheel 2 can be turned 90 degrees or 180 degrees accordingly. At this time, the outer edge of the handle reset wheel 2 and the pressure arm 21 And the interaction of the handle return spring 22, the installation direction of the door handle 16 can be set. When the system is installed in the door body, at this time, according to the rotation angle of the lock body when unlocking and the agreement of the interaction between the outer shell of the limit table 34 and the outer shell of the locking spring pin 4, the door handle 16 is controlled in the normal unlocking state. The angular range of the required rotation.

when using it:

In daily use, when the outdoor personnel want to realize the illegal unlocking of the door lock, the push rod of the motor coupling 5 is extended according to the agreement, and the interaction between the locking head 41 and the locking table 31 in the unlocking direction is blocked by pushing and keeping the locking head 41 and the locking table 31. If the door handle 16 cannot be rotated in the unlocking direction, illegal unlocking can be prevented.

When indoor or outdoor personnel want to lock the door lock, although the push rod of the motor coupling 5 is extended according to the agreement, the locking head 41 and the locking table 31 do not interact with each other in the locking direction of the lock, and the door is opened. The handle 16 can be rotated in the locking direction to realize the locking of the lock.

When the outdoor person unlocks normally, the system will send an unlock command to the motor clutch 5, and the push rod 51 will be shortened and retracted. At this time, under the action of the locking pin spring 42, the locking head 41 will follow the push rod 51. The table 31, at this time, according to the agreement, the door handle 16 can be rotated in the unlocking direction to realize the unlocking of the lock.

When the indoor person unlocks normally, the push rod 89 in the taper button 81 and the acupressure button 88 can contact and cooperate with each other through the bolt inner hole 90 in the hollow bolt 91 according to the agreement. At this time, it is only necessary to use the thumb to press the acupressure button 88 provided in the door handle 16 while holding the door handle 16, and to drive the taper-split button 81 to act on the thrust pin 8. At this time, according to the agreement, the thrust pin 8 It can be moved to the outer edge of the locking table 31, and the locking head 41 can be pushed away from the locking table 31. At this time, according to the agreement, the door handle 16 can be rotated in the unlocking direction to realize the unlocking of the lock.

The above are the embodiments of the present invention and are not intended to limit the concept and application of the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that it is still possible to modify the technical solutions described in the foregoing embodiments, or to equate any or all of the technical features therein. Replacement; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention, and should be included in the scope of the claims and description of the present invention.
