Abstract
The utility model relates to a double-clutch anti-theft lock cylinder with a knob. The double-clutch anti-theft lock cylinder with the knob comprises a core and a central shaft in sequence, wherein the central shaft is sleeved with an outer clutch and an inner clutch in sequence, a shaft core spring used for providing axial restoring force for the outer clutch is arranged between the central shaft and the outer clutch, and a knob spring and the knob are arranged at the tail end of the inner clutch in sequence. The double-clutch anti-theft lock cylinder with the knob is characterized in that a clamping spring is arranged between the outer clutch and the inner clutch, and a clamping spring groove used for installation of the clamping spring is formed in the central shaft. According to the technical scheme, due to the combination of the outer clutch and the inner clutch, an anti-theft door can not be opened from the outside with a tool without opening the anti-theft lock cylinder; when the lock cylinder is opened with a key, the knob does not rotate along with the rotation of the lock cylinder, and therefore the double-clutch anti-theft lock cylinder with the knob can be better applied to electronic locks.
