The present invention discloses a door lock structure for a pet cage. The door lock structure comprises a cage body on which at least one entrance and exit and a cage door matched with the entrance and exit are arranged. A plurality of pivot rings is arranged on one side of the cage door, sleeves a door frame on the edge of the entrance and is rotatable about the door frame. At least two limit sliding rods which are parallel to each other are arranged on the cage door, and a lock that is slidable on the limit sliding rods is installed on the limit sliding rods. The lock comprises a traveling mechanism that clamps the limit sliding rods, and a plurality of tension springs is installed on one side of the traveling mechanism close to the door frame. A plurality of lock bolt assemblies that moves synchronously with the traveling mechanism is also arranged on the traveling mechanism, and the lock bolt assemblies are matched with and locked with lock hole mechanisms provided on the corresponding door frame. The door lock structure is simple and exquisite in structure and design. Through the joint action of the traveling mechanism, the lock bolts and the tension springs, on the one hand, a plurality of lock bolts can be controlled at the same time; on the other hand, a plurality of parts of the cage door can be locked. The door block structure is simple and reliable and is easy to operate.

A galley bay door system comprises a slider housing configured to be mounted in a galley bay door. The system also includes a slider mounted in the slider housing and configured for sliding movement relative to the slider housing, a slider plate mounted to the slider for movement together with the slider. A method comprises securing contents in a galley trolley with a door on the galley trolley and providing secondary retention for the contents in the galley trolley by closing the galley trolley inside a galley bay with a door of the galley bay.

A manually operated locking bolt (1) having a cylindrical, sleeve-shaped bolt guide (3) and a bolt (2), which is mounted to be axially displaced in the bolt guide (3), and which has a locking end (15) and an actuating end (31), wherein the bolt (2) is mounted to be axially displaced between a first axial end position or a second axial end position within the bolt guide (3) and can be locked, wherein at least one sensor (27) is fastened to the bolt guide (3), which sensor detects the two axial end positions of the bolt (2) as a measured variable and generates therefrom a further processable electrical signal.

A locking device for a barn door mounted in the wall adjacent a side edge of the door when in the closed position. The lock includes an outer cylinder that passes through the wall. The ends of the outer cylinder are mounted to each side of the wall. An inner cylinder is provided that is axially and slidably disposed within the outer cylinder and has a length greater than the length of the outer cylinder. When so positioned, one end of the inner cylinder can extend from the surface of the wall to prevent the barn from sliding to an open position by contacting the side edge of the barn door. When slid in the opposite direction the inner cylinder disengages from contacting the side edge of the barn door to enable the barn door to slide to the open position. Optionally, a locking mechanism is provided to lock the barn door in the closed position.

A door locking mechanism includes a main body, a trigger, and a slide lock. The slide lock and the main body are configured such that at least a portion of the slide lock extends outside of the main body in a locked position, with the slide lock being advanced into the main body as the slide lock transitions toward an unlocked position. A ball lock is in operative communication with the trigger and the slide lock, with the ball lock, the trigger, and the slide lock being configured such that when the trigger is in the extended position, the ball lock inhibits movement of the slide lock from the unlocked position toward the locked position. Movement of the trigger from an extended position toward a retracted position allows the ball lock to assume an unobstructed position allowing the slide lock to transition from toward the locked position.

The present invention relates to a bidirectionally operating warfare lock mechanism (C) that prevents external interference (opening/unlocking) to hatches in military vehicles (A) during combat. The present invention particularly relates to a bidirectionally operating warfare lock mechanism (C) comprising a lock operating mechanism (100) that is connected to the vehicle (A) and that allows for opening and locking the hatch (B) when the user moves the lock lever (110) to P1 (161) and P2 (162) receptacles, and further comprising a lock bolt mechanism (200) that can be easily mounted by being rotated 180° around its axis without making any changes in the design, thereby allowing for being used in always-open or always-closed (locked) configurations according to the desired scenario.

An electronic lock includes a control circuit module and an electromagnetic mechanism. The electromagnetic mechanism is electrically connected to the control circuit module, and the electromagnetic mechanism includes a driving member and a magnet. The driving member is configured to be driven by the control circuit module to be located at one of a first position and a second position. When the driving member is not driven by the control circuit module, the driving member is configured to be held at one of the first position and the second position by the magnet.
