Abstract: An outer handle structure of a lock that may be idle includes an inner handle set provided with an inner handle for driving an inner drive shaft to rotate. The inner drive shaft drives a retractor to operate. The inner handle set is additionally provided with a press button that may be pressed to drive a safety bar to push a limit plate and a lock snap plate. A outer handle set is provided with an outer handle for driving an outer drive shaft to rotate. The outer drive shaft defines an annular slot and a straight slot arranged in a T-shape. A latch release set is provided with a retractor for drawing a lock tongue of a lock latch to operate, and has two ends respectively pivoted with the inner drive shaft of the inner handle set and the outer drive shaft of the outer handle set.

Abstract: A remotely controllable lock includes a turn knob rotatably mounted to a main housing. The turn knob includes an axle rod with a non-circular hole through which a spindle of the lock extends. A power element is mounted in the main housing for driving a relatively larger gear of a power device. The relatively larger gear and a relatively smaller gear are integrally formed on a common shaft that has two ends to which two slide blocks are pivotally mounted, respectively. The slide blocks are mounted in a receiving hole in the main housing and a receiving hole in a fixing plate. The slide blocks are biased by elastic elements. One of the slide blocks includes a stub that extends beyond the associated receiving hole to come in contact with a sensor. The sensor sends out a signal to stop the power element. The relatively smaller gear meshes with a control gear of a control device. The control gear is rotatably mounted around the axle rod of the turn knob.

Abstract: A lock core assembly is provided for a cylindrical lock. The cylindrical lock includes a knob having a lock core opening defined in an end face thereof and a spindle projected outward from the other end face thereof. A slot extends along the spindle and includes an extension extended into the other end face, thereby defining two stop wall portions on two opposite sides of the extension of the slot. The lock core assembly includes a barrel and a lock core rotatably mounted in the barrel. The barrel includes a protruded top portion with two lateral wings bearing against the stop wall portions of the extension of the slot.
