A door bolt structure of an electronic device includes a door frame, a door panel, and a resilient metallic wire. The door panel is movably disposed at the door frame and provides a hermetic seal to the door frame. The two ends of the resilient metallic wire are connected to the door panel. The resilient metallic wire bends to form hook portions which protrude from the edge of the door panel. When the door panel provides a hermetic seal for the door frame, the hook portions are engaged with an inner edge of the door frame. When pulled, the resilient metallic wire drives the hook portions to separate from the door frame, thereby allowing the door panel to move relative to the door frame.

A sliding door for a metal wired pet cage includes a pair of torsional springs; a rotary locking member; a rotary lifting handle; and a sliding-type door plate; wherein sliding guide rails of the sliding door are configured longitudinally, wherein the lifting handle is hingedly fixed to an upper end of the sliding-type door plate, the pair of torsional springs are fixed on the metal wired pet cage and are connected with both ends of the locking member, and the torsional springs is configured to drive the locking member to prop against the lifting handle so that the sliding-type door plate is at a locking state. When the sliding type door plate needs to be opened, the lifting handle is rotated upwards so that the locking member is separated from the lifting handle, and the lifting handle drives the sliding-type door plate to move upwards along the sliding guide rails.

An aircraft door latch arm rotation limiting device incorporates a flexible strap having a proximal end and distal end. The distal end is insertable through a loop eye proximate to an aircraft door. An elongate sleeve is disposed on the proximal end of the flexible strap and the sleeve is received over a rotatable latch arm of an aircraft door. A first receiving element intermediate the proximal and distal ends of the flexible strap releasably engages the distal end of the flexible strap to establish a first predetermined looped strap length restricting rotation of the lever beyond a partially open position. A second receiving element is disposed between the first receiving element and the proximal end on the flexible strap to releasably engage the distal end to establish a second predetermined looped strap length preventing rotation of the lever from a closed position.

A novel proposition is herein presented for providing a safe and user-friendly door especially for logistics containers. The door includes a quadrilateral frame, which defining the perimeter for the door. A latch is provided movably to the frame so as to be manipulated between a locking state, in which at least a distal portion of the latch protrudes outside said perimeter, and a released state, in which the distal portion is flush with or inside said perimeter. The frame also includes a diagonal guide, which is configured to guide the latch between the locking state and the released state by allowing deviation of the latch along a path diagonal to the quadrilateral shape of the frame.

The present invention relates to a filtration assembly for filtering a fluid flowing in particular in a motor or a hydraulic equipment, comprising: a filter body having a tank and a cover, the filter body being intended to house a filter cartridge, at least one locking system for the filter body, being movable between a locking position and an unlocking position, wherein said filtration assembly has means for holding the locking system (5) in the unlocking position.
