AI Technical Summary
When existing smart lock cabinets are pried open by external force, the lock tongue is easily dislodged from the groove, resulting in limited anti-theft effect and insufficient security.
The worm gear mechanism driven by an electric motor, through the cooperation of the worm, worm wheel, gear and slide bar, enables the slide bar to rotate counterclockwise and clockwise in the slide rail, ensuring a tight connection between the lock body and the mounting block and enhancing the anti-theft performance.
Even when the side panel of the cabinet is pried open by external force, the sliding strip can still hold the mounting block, which increases the safety of the cabinet and improves the anti-theft effect.
