Embodiment Construction

[0032] The present application will be described in further detail below through specific implementation methods and accompanying drawings.

[0033] The multi-directional locking device for the automatic lifting of the containerized cargo system of civil aircraft provided by the present invention includes: locking bolt 1, base 6, linkage lever 2, limit rotating arm 4 and unlocking rotating arm 8,

[0034] Wherein, the locking bolt 1 is located on the left side of the base 6, and the locking bolt 1 is connected to the base 6 through a hinge. The linkage rod 2 is located in the middle of the locking dead bolt 1, and the two ends of the linkage rod 2 are hingedly connected with the locking dead bolt 1 respectively.

[0035] In the present invention, the locking bolt 1 has four limit surfaces, wherein the vertical limit surface 15 is located above the lock tongue, the course limit surface 14 and the reverse course limit surface 17 are located on both sides of the vertical limit su...

Abstract

The invention provides a multi-directional locking device for automatic lifting of a container type freight system of a civil aircraft, and belongs to the field of air freight. A locking spring bolt of the multi-directional locking device is located on the left side of a base, and the locking spring bolt is hinged to the base. A linkage rod is of a U-shaped structure and located in the middle of the locking spring bolt, and the two ends of the linkage rod are hinged to the locking spring bolt. Oblong hole sliding grooves are formed in the two sides of the linkage rod, a limiting rotating arm is located in the middle of the linkage rod, and the limiting rotating arm is hinged to the base and the linkage rod. An unlocking rotating arm is located on the left side of the linkage rod, an acute-angle groove is formed in the middle of the unlocking rotating arm, a long round hole is formed in the tail end of the unlocking rotating arm, the acute-angle groove structure makes contact with a linkage rod boss, and the long round hole is used for providing idle stroke for the acute-angle groove of the unlocking rotating arm to break away from the structural limit of the linkage rod. The problems that an existing similar locking device cannot limit the heading direction, the lateral direction and the vertical direction of a container unit at the same time, and the outer contour of the locking device cannot automatically descend to the position below a conveying plane under contact of a bottom structure of the container unit.

Description

technical field [0001] The application belongs to the technical field of air cargo, and in particular relates to a multi-directional locking device for automatic lifting of a containerized cargo system of a civil aircraft. Background technique [0002] The locking device is matched with the containerized cargo system of civil aircraft, and is usually installed in the standard floor slide rail or the transmission roller installation frame, and is used for the reliable direction, vertical or reverse course, and vertical direction during the air transportation of civil container units. Limiting, the reasonable design of the limiting mechanism can ensure that the container unit is accurately locked at the position required by the cargo system, and the various loads generated by the container unit are transmitted to the main load-carrying frame beam of the aircraft through the two-way locking device. [0003] In related technologies, the locking device of civil aircraft container...
