Telecommunications enclosures (10, 110) and related methods are disclosed. In one aspect, the enclosure (10) includes a base (20), a cover (40), a lock assembly (70) for securing the base (20) to the cover (40), and a key (60) for operating the lock assembly (70). In one aspect, a lock clip (80) of the lock assembly (70) enables operation of the lock assembly (70) when the cover (40) is in the closed position. In another aspect, the lock clip (80) disables operation of the lock assembly (70) when the cover (40) is in the open position such that the lock assembly (70) is prevented from being operated out of the open position. In yet another aspect, the key (60) is prevented from being removed from the cover (40) when the key (60) operates the lock assembly (70) out of the locked position.

A latch mechanism is provided that includes a housing, a cap, and at least one indicator. The cap may include a central axis and may be mounted for selective rotational movement relative to the housing about the central axis between a latched position and an unlatched position. The at least one indicator may be interposed between the cap and the housing, such that the cap is in covering relationship to at least a portion of the at least one indicator. The at least one indicator may also be mounted for radial movement outwardly from the central axis relative to the cap as the cap is rotated from the latched position to the unlatched position such that the cap is no longer in covering relationship to the portion of the at least one indicator.

A fix position device for casement latch includes a housing including a cavity, a through hole, first and second limit members, a hole having one end communicating with the cavity and the other end formed with threads, a spring biased steel ball in both the hole and the cavity, and an adjustment screw secured to the threads; a bolt including a cylindrical axis partially in the through hole, a channel having a square section and formed through the axis, two recesses on a periphery of the axis, and an engagement member at the other end; a cover plate including a central hole with the axis partially disposed therein; a face plate including an intermediate slit with the engagement member passing through; and a handle assembly including a peg member having a square section projecting through the channel, and a lever having one end co-rotated with the peg member.

An adaptive electric dual-controlled intelligent lock includes a mechanical clutching structure and an intelligent electronic control structure. The mechanical clutching structure includes a lock head, a lock cylinder and a lock tongue, wherein: the lock cylinder includes movable buckles, springs and a bearing. After being inserted into the keyhole of the lock head and then into the locked groove, a key is turned, the movable buckles move in an elastic range of the springs and drive the lock tongue connected with the bearing to swing, thereby realizing a mechanical unlocking process. The intelligent electronic control structure includes a PCB (printed circuit board), a motor and a shifting lever, wherein: a wireless control module is connected with an external mobile intelligent device; after the motor is started, the shifting lever pushes the movable buckles, so that the bearing drives the lock tongue to swing, thereby achieving an intelligent unlocking process.

A charging cart includes a casing, at least one door leaf and a hooking mechanism. The casing has at least one first hooking slot. The door leaf is pivotally mounted to the casing so that the door leaf is rotatable relative to the casing about a first rotation axis. The hooking mechanism includes a movable assembly and at least one hooking member. The movable assembly is movably disposed on the door leaf. The hooking member is connected to the movable assembly. The hooking member is driven by the movable assembly to rotate relative to the door leaf about a second rotation axis to be moved between a locked position and an unlocked position. The second rotation axis is parallel to the first rotation axis.

A weather resistant pin lock with an elongated body, defining a longitudinal axis includes a shell housing a rotatable core having a keyway. An elevated pinway projects upwardly from the shell to define a linear array of pin slots containing a set of lock pins. A hood is fastened to the pinway to hold the lock pins in the pin slots and to provide a water resistant barrier. A drainway provides a channel for water to flow outwardly from the interior of the shell, the rotatable core and the keyway within the core, to a drain below the pin lock. At the proximate end, an access door rotates adjacent the keyway at an elevated position, to provide a gap along the bottom edge of the access door.

A twist handle latch assembly is provided for use on compartment doors of a utility vehicle. The assembly includes a plastic housing with a steel backer plate to which the latch pawl is mounted. A T-handle is rotatably mounted on the front of a housing with a post extending through the housing and the steel plate for connection to the latch pawl. Rotation of the handle rotates the latch pawl between locked and unlocked positions. A power actuator may be provided to remotely lock and unlock the latch pawl. A key cylinder actuator allows manual locking and unlocking of the latch pawl. A cam connected to the actuator has a window to receive a portion of the pawl in the locked condition.

A molded access door assembly for an access opening in a wall or ceiling is provided. It includes a molded frame with a frame channel forming the outside of the access door assembly. The frame channel has spaced apart exterior and interior walls joined at the top edge by a top wall and a lip extending from the bottom edge of the inner wall into the interior of the molded access door assembly to define an opening. The lip provides a stop rest for the door in the closed position so that the door is capable of being attached to the wall or ceiling. The assembly also includes a door having a top surface and a first part of a hinge assembly along one edge of the top surface which cooperates with a matching second part of the hinge assembly along one edge of the frame channel to allow the door to move between an open and a closed position.

A dual cam lock apparatus comprising a locking blade, a rotatable lock, a first cam and a second cam. The first cam comprises a first cam body and a first arm extending from the first cam body. The first cam is rotatable by the rotatable lock to move the first arm in and out of contact with the locking blade. The second cam comprises a second cam body with at least one slot therethrough which receives at least one protrusion of the first cam, and a second arm extending from the second cam body and coupled with the locking blade. The slot has an angular span across which the protrusion rotates before further rotation of the protrusion causes rotation of the second cam, whereby rotation of the second cam rotates the second arm to move the locking blade between the locking and release position.

Lock assemblies having cylinders with interchangeable cores are provided. In one embodiment a lock assembly comprises a cylinder including a keyway and a core. Also, the lock assembly includes a first driver operatively connected to the cylinder. In particular, key cuts of the core are changeable without removing the cylinder from the driver.
