Abstract
The utility model relates to an emergency unlocking device for an electronic puzzle lock clutch washer of a manhole cover, and the utility model is composed of a lock core, a pin and an emergency spanner. Axis holes are arranged in the center of the clutch washer, and the bottom of the clutch washer is provided with three spherical surface convex hulls. The spherical surface convex hull is freely sheathed on a rotating shaft after the spherical surface convex hull is matched with a turntable, and both sides of the clutch washer are respectively provided with a die stop plate. The die stop plate enters a cavity positioned in the center of a round nut through a threaded hole, and the tail end of the die stop plate bends 90 DEG and is clamped in the inner end surface of the cavity of the round nut. The lower part of the round nut closely approaches to the clutch washer and the turntable; a through hole is arranged in the center of the turntable, which is matched with the rotating shaft; three small holes are evenly distributed along the periphery of the through hole to connect with a turntable locking port. The emergency unlocking is divided into two steps: firstly, the end of a screw claw of the emergency spanner dials the round nut and the clutch washer driven by the round nut disengages the turntable. Secondly, one end of a sleeve pipe steel ball is inserted into the turntable locking port, a round column end of the screw of a handle is rotated to press the steel ball into the turntable locking port, a casing tube is clamped to run in clockwise rotation and the steel ball driven by the casing tube sends the torque to the turntable locking port.
