In an embodiment of the present disclosure, a latch assembly for an access panel of a housing includes a latch structure having a first surface, a second surface, and an intermediate step therebetween. The latch assembly also includes a fastener configured to facilitate coupling of the first surface to the access panel, and a locking system configured to engage with a structural support of the housing via the second surface. The locking system is configured to be rotated to secure the second surface to the structural support and rotated to release the second surface from the structural support.

A latch structure includes a moving member, a nut and a screw. The moving member includes a base plate, a receiving portion and a limiting portion. The receiving portion has a first end portion and a second end portion. The first end portion is connected to the base plate. The limiting portion is disposed at the second end portion of the receiving portion. The nut is fixed into the receiving portion and positioned proximate to the first end portion. The screw is received in the receiving portion and confined to between the limiting portion and the nut.

The application belongs to the technical field of LED display screen box assembly, and relates to a tension lock and LED display screen box. The tension lock comprises a base, a rotating shaft, a shim and a knob, wherein the base is provided with a sliding hole, one end of the rotating shaft is fixedly connected with the knob, the other end of the rotating shaft is inserted into the sliding hole, the shim is rotationally connected with the rotating shaft, and the distance between the shim and the knob is kept constant; Turning the knob can make the rotating shaft rotate and slide along the axial direction of the sliding hole to make the shim move away from or close to the base. The tension lock can effectively improve the installation efficiency of LED display screen box.

Provided is a door latch including a latch mechanism, secured to an appliance such as a self-cleaning oven, which locks an appliance door to the appliance. The latch mechanism includes a latch bracket mounted to a surface of the appliance. A latch hook is mounted within the latch bracket for reciprocal movement between locking and unlocking positions. The latch hook pivotally engages a receptacle mounted on the door, to lock the door to the appliance. A flexible cable is retained inside a flexible conduit. A first end of the flexible cable is connected to the latch hook for displacing the latch hook into the locking position for pivotal engagement with the receptacle. An electric actuator is connected to a second end of the flexible cable for producing operative movement of the flexible cable within the flexible conduit to displace the latch hook between the locking and unlocking positions.

A door opening/closing device including a door, a locking hook mounted on an inner surface of the door, a solenoid mounted in a device housing, a locking lever connected swingably to a movable iron core of the solenoid and having a free end on an opposite side of a connection portion, and a controller for controlling the solenoid, in which the controller executes control so as to, if the door is closed and locked, separate the locking lever from the locking hook to release locking in conjunction with the movable iron core retreated by an electromagnetic attracting force by executing conduction control of the solenoid, and maintain an unlocked state while the door is closed by executing non-conduction control of the solenoid after unlocking and bringing the free end of the locking lever into contact with the locking hook by a return spring force.

An equipment carrier holding device has a housing with a door. A screwing block is arranged in the housing. A clamping block and a fastening screw fix a fastening link of an item of equipment between the clamping block and the screwing block. The clamping block is positioned in relation to the door such that, in the event of incomplete arresting of the fastening screw, the fastening screw forms a mechanical barrier to complete closing of the door. A rail vehicle is also described which is equipped with such an equipment carrier holding device.
