This invention discloses a high strength security lock cylinder. The lock cylinder includes a front lock housing, a front lock plug, a rear lock housing, a rear lock plug, a horizontal bar, and a lock cam. The front and rear lock plugs are connected with the lock cam and can drive the lock cam to rotate. An electronic locking mechanism is placed inside the front lock plug. The rear lock plug is connected with an axel, which is connected with a knob that contains a digital control board and an electrical power source. A signal transmission channel is formed along the horizontal bar for transmitting signals between the electronic locking mechanism and the digital control board. The lock cylinder is flexible, strong, and resistant to drilling and lock picking and it can be digitally controlled. This reduces the security risks caused by misplacement or unauthorized use of keys.

A cylinder lock (100) comprising first and second housing sides (104, 106), an actuator (120) which is positioned in a space (116) between the first and second housing sides (104, 106), and a connecting portion (200) which extends completely across the space (116) and connects the first and second housing sides (104, 106), and wherein the actuator (120) is rotatable about the connecting portion (200) in order to cause operation of locking means. The connecting portion (200) gives the cylinder lock (100) increased strength.

A cylinder-lock assembly configured to allow affixing accessories that are designed to be operatively coupled with a standard European locking cylinder to operate an American mortise type lock system. The cylinder-lock assembly includes a cylinder-lock-member that includes a cylinder-housing having an external shape of a European cylinder-housing, and a cylindrical lock core. The cylinder-housing defines a cylindrical through bore configured to receive the cylindrical shaft, and the cylindrical shaft is adapted to rotate there inside the cylinder-housing. The cylinder-lock assembly further includes an adapting-ring, a cylindrical American housing and a rotation-conveyor, configured to operatively convey rotational motion of a fitted key, which is disposed inside the cylindrical shaft, to an American-lock type cam, to thereby actuate the door lock/unlock mechanism of the American type mortise lock.

A lock body for a pin lock is of multipart construction and has a main body and a divider, mounted on the main body, with a plurality of bores for receiving springs and locking pins. The mechanical division of the lock body into the main body and the divider allows simpler and more cost-effective production since the lock body no longer needs to be complicatedly machined out of a solid material, for example brass, but rather more cost-effective production methods can be used.

A barrier device for a locking device is provided with a stator and with a rotor as two components and with a barrier element. The rotor is mounted in the stator. The barrier element is mounted in a first component of the components and can be moved between a first position and a second position. In the first position, the barrier element engages in a second component of the components. In the second position, the barrier element is disengaged from the second component. The second component has a first contact surface for the barrier element, which moves the barrier element from the first position into the second position when the rotor rotates. The second component further has a second contact surface for the barrier element, which leaves the barrier element in the first position when the rotor begins to rotate. A locking device is provided with the barrier device.

A cylinder lock assembly includes a plug rotatable in a cylinder lock body. The plug includes chambers, each of which has a chamber depth axis. A plurality of thin, planar plug locking elements are received in the chambers. Each plug locking element has a key cut interface probe for interfacing with a key cut formed on a key. Each plug locking element is arranged to move along the chamber depth axis and does not rotate about the chamber depth axis. Each key cut interface probe has a predetermined orientation with respect to the chamber depth axis.

A cylinder lock that can be simply assembled and disassembled has a cylinder housing, a bridge and a cam. In the cylinder housing, a first locking pin is fixedly received in a locking pin bore. The locking pin passes a cylindrical recess in the cylinder housing transversely. A first cylindrical end of the bridge is provided with a locking pin recess and with a flattened side which extends at least from a free end, remote from a central part of the bridge, of the first cylindrical end of the bridge up to and including a first locking pin recess. The bridge can be simply connected with the cylinder housing by inserting the first cylindrical end of the bridge into the cylindrical recess in the cylinder housing and by thereupon rotating the bridge through an angle, such that the locking pin extends in the locking pin recess in the bridge. After that, with a locking bolt the thus assembled whole can be locked.
