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.

A locking mechanism is provided. The locking mechanism includes a base, a connecting rod, a fastener, and a linking member. The connecting rod and the fastener penetrate the base and are rotatable relative to the base. The connecting rod and the fastener are disposed parallel to each other. The linking member is connected to the connecting rod and the fastener, and is configured to link up the connecting rod and the fastener. Accordingly, the locking mechanism may be suitable for an expansion device with a specific size, and therefore the performance and the design flexibility of the electronic apparatus may be enhanced.

The disclosure relates to a closure device for attaching to a robot, preferably quick closure device and/or for overpressure-tight closing of a cavity of the robot up to at least 175, 200 or 225 mbar. The closure device comprises a removable covering element for covering a cavity of the robot and a fastening apparatus for fastening the covering element to the robot, wherein the fastening apparatus comprises a rotatable closure element. The fastening apparatus is characterized in particular in that it has a rotational closing movement between 45 and 215 and thus can be moved by a rotational closing movement between 45 and 215 into a closure position.
