Described herein are example fluid guards that can be used with locking devices. Various aspects may be particularly applicable to electrical locks, but they may also be applicable to mechanical locks. A locking device guard can include a guard cover, a fluid absorber, and a coupling element. The fluid absorber can be configured in a closed configuration to fit at least partially within a cup of a lock face. The coupling element can be configured to couple the guard cover to the lock and can define a second axis. The coupling element can be configured to allow the guard cover to rotate about the second axis.

An embodiment door outside handle assembly includes a door lock body configured to be attached to an outside of a door panel of a vehicle, a grip cover covering an outside of the door lock body and including a key hole configured to receive an emergency key, and a door lock cap on an outside of the grip cover, the door lock cap being slidable in a longitudinal direction of the vehicle to cover or uncover the key hole.

Provided is an outer handle device for a vehicle door includes an outer handle and a cover. The outer handle includes a handle body that is disposed outside an outer panel of the vehicle door and extends in a front-rear direction of a vehicle. The cover is configured to cover, from an outside of the vehicle door, a cylinder lock located in a position adjacent to a first end of the handle body. The cover is configured to be attached to the outer panel and has an extension part, and the outer handle is turnable between a non-operation position and an operation position. While the outer handle is in the non-operation position, the extension part is engaged with a first end of the handle body and overlaps the first end of the handle body in a side view. While the outer handle is in the operation position, the engagement between the extension part and the first end of the handle body is released, and the cover is attachable to and detachable from the outer panel.

A steering column lock comprises a bearing-mounted, free-rotating keyhole cover that covers an underlying locking device. When installed on the steering column of a vehicle, the steering column lock prevents a would-be car thief from grabbing the lock with pliers or another tool and using the lock to turn the steering column and thus drive the vehicle, because rotation of the free-rotating outer cover does not cause rotation of the other portions of the lock.

The COMBINATION DEADBOLT LOCK COVER is a cover that goes over the deadbolt to keep lock-pickers from gaining access to the deadbolt lock of a dwelling. It consists of two components. The first component is the cover that you place the outside locking mechanism of your deadbolt inside and secure it to the hole on your dwelling door that the deadbolt originally goes. Once you screw your deadbolt lock with the COMBINATION DEADBOLT LOCK COVER securely covering your deadbolt lock then you slide the second part of the COMBINATION DEADBOLT LOCK COVER which is a DROPDOWN PLATE into a prefabricated slot to render the deadbolt lock of your dwelling completely un-accessible. The DROPDOWN PLATE has a hole in it in which you can slide a combination lock or a standard lock into making the deadbolt lock on your dwelling door un-seen and un-accessible.

Proposed invention is an alarm device for protecting various type of locks of premises, buildings, apartments, rooms, vehicles, safes, money terminals and for other objects by means of timely, more early informing, interaction with alarm system or digital-electronic device of persons observing protected object in result of attempts of burglary, unauthorized opening, damaging or even preliminary studying the lock by attacker.

The present invention is inherent to a swing-type Shape Memory Alloy (SMA) actuator (10) comprising a stationary frame (11) and a swingable part (12) that are coupled by means of a pivot (13) allowing the swing of the swingable part (12), two SMA wires (14, 14) being engaged to two connecting elements (15, 15) present respectively on a left and right portion of the swingable part (12) and vertically separated from the pivot (13), such that the activation of one of the SMA wires (14, 14) causes the swing of the swingable part (12) in either the clockwise or counter-clockwise direction.

A rotary locking mechanism and a lock applying the rotary locking mechanism and a locking control method are provided. A rotary output member is locked by a stable triangular supporting structure between the first locking member and the second locking member, the effective constraint of the second locking member on the first locking member applied by the first locking member in both a locked state and an unlocked state achieves locking and unlocking reliability of the product. The entire locking mechanism is controlled by the same switching member. The false locking operation when the rotary member is operating is effectively avoided through the mechanical structure and the automatic control method. The entire rotary locking mechanism is enclosed and fixed in a shell of the lock, and can be applied to transmission machinery of bicycles, electric vehicles, motorcycles and even lightweight automobiles.
