Method of securing and screening luggage with dual-function locks that the TSA and similar luggage-screening entities can open to screen checked air travelers' luggage.

The present disclosure discloses an electronic handle door lock structurally which includes a rear handle, a front handle, a lock body arranged between the rear handle and the front handle, a clutch rotating rod rotatably arranged at an inner side of the front handle, a control circuit board installed on one side of the front handle, and an linkage square pipe penetrating through one side of the lock body and connected between the rear handle and the front handle, wherein the linkage square pipe is connected with the clutch rotating rod, one side of the front handle is provided with a battery case installing slot, one side of the battery case installing slot is detachably provided with a contact type battery case, and an inner side of one side of the battery case installing slot is provided with an electrically conductive plate electrically connected with the control circuit board.

A lock has a cable engageable with a lock body. The cable has two ends, each of which has a cable neck. The lock has a shaft operatively engaged with a stack of clutches and a plurality of dials. The shaft has a top portion with a shaft slot engageable with the cable neck on the first cable end. The first cable end can be released from the lock body with a combination mechanism. The lock has a fixed cam having a cam slot engageable with the cable neck of the second cable end. The lock further comprises a blocking plate slideably engaged with the fixed cam, and a rotatable cam configured to control the positions of the blocking plate. The rotatable cam is connected to a cylinder operable with a key to rotate the rotatable cam to release the second cable end from the fixed cam slot.

A lock has a hook and a locking finger to form a locking loop. The hook is fixedly attached to the lock body, whereas the locking finger can be pivoted to disengage from the hook to open the lock. The pivotal movement of the locking finger is controlled by a latch and an extended edge. The latch has a tip and the locking finger has a cut-out to receive the tip when the lock is locked. When the lock is locked, a spindle prevents the extended edge from moving toward the latch for releasing the tip from the cut-out. When the lock is opened by the combination mechanism, the spindle is moved away to allow the extended edge to move toward the latch to release the tip from the cut-out. When the lock is opened by the key mechanism, turning the cylinder causes the extended edge to move the latch downward.

A locking system for a door, including a primary locking mechanism and a secondary locking mechanism, in which the primary locking mechanism includes an electrical actuator that causes a first plate and a second plate to be magnetically attracted to one another when actuated such that rotation of a doorknob effects a corresponding rotation of the spindle, and in which the secondary locking mechanism includes a detent that is formed in a knob collar and an aperture that extends through a rotator collar; and a pin that is translatable through the aperture to be disposed in the detent of the knob collar, when the secondary locking mechanism is in an unlocked condition, such that the knob collar and the rotator collar are rotatably fixed to one another.

A combination lock can be operated manually via the manipulation of dials and by way of an electronic key. The lock includes one or more rotatable selectors each having multiple indicia disposed thereon. Rotation of the rotatable selectors to predetermined indicia places the lock in the unlocked position. The lock can further include an electronic port and an actuator. Upon receipt of a predetermined credential via the port, the actuator can place the lock in in the unlocked position. The lock further includes a knob that, when the lock is in the unlocked position, can be rotated between a first position in which the lock is in a closed position and a second position in which the lock is in an open position. The combination lock may automatically scramble the positions of the dials upon opening for security purposes.

An electronic storage cabinet lock includes a lock housing, a lock core, a circuit board, a motor assembly, a clutch mechanism and a battery assembly that are installed in an outer shell. A button assembly and a handle are mounted on the outer side of the outer shell. A cam is mounted on the motor assembly. One end of the lock core is secured in a shaft hole of the handle. When a password is correctly inputted, the button assembly transmits information to the circuit board to control the motor assembly to operate. The cam is driven to rotate to control the open state or closed state of the clutch mechanism. The handle can rotate to drive the lock core to rotate, thereby rotating a lock tongue to open the lock.

A combination lock comprises a lock body, a key lock assembly and a digital combination lock assembly, wherein the key lock assembly includes a lock cylinder and a locking hook sleeve, the lock body is internally provided with an indicating rod and a slider, a first inclined surface is disposed at the bottom of the indicating rod, and the slider is provided with a second inclined surface and a third inclined surface; the locking hook sleeve is provided with a fourth inclined surface; and the lock body is provided with an indicating hole, and the indicating rod can protrude upward from the lock body under the pushing action of the slider. Whether the lock has been unlocked can be judged by the indicating rod.

Method of making airline luggage inspection secure while accommodating the needs of the traveler comprises making a special lock available to airline travelers, the special lock having a combination lock portion and a master key lock, the master key lock portion receiving a master key that can open the master key lock portion of any special lock of this type. The special lock is designed to be applied to an individual piece of airline luggage and has indicia conveying to luggage purchasers that the special lock is approved by a luggage screening authority and conveying to the luggage screening authority that the special lock can be opened using the master key. The method includes providing the luggage screening authority directly or indirectly with exclusive access to the master key. The manufacturers and/or providers of the master key and special lock retain copies of the master key.
