Lock cylinder resistant to technical unlocking
A lock cylinder resistant to technical unlocking comprises a lock shell, a lock liner and ball assemblies. Balls of one or more ball assemblies are composed of a main ball and balls resistant to technical unlocking, wherein the main ball and the balls resistant to technical unlocking are connected into a whole; conical grooves are formed in each ball resistant to technical unlocking; a pin, a hollow sealing cover and a pin reset spring used for resetting the pin are arranged inside each pin hole; when a door is locked, each pin can hide in the corresponding pin hole in the lock liner as well as be partly exposed into a pin sliding insertion hole or an insertion groove in the lock shell. A lawbreaker has to rotate the lock liner slightly when unlocking a lock technically, the pins in the lock liner rotate slightly at the moment, then the outer end of each pin is exposed and clamped in the corresponding pin sliding insertion hole or the corresponding insertion groove in the lock shell, or the two ends of each pin abut against the slope of the corresponding conical groove and the inner wall of the lock shell respectively under the action of the slope of the corresponding conical groove, and the lock liner can not continue to be rotated to unlock the lock in any way, so that the purpose of being resistant to technical unlocking is achieved. The lock cylinder resistant to technical unlocking is more reasonable in structure and higher in anti-theft property.
