Abstract

The present application provides a multi-directional locking device for the automatic lift of a containerized cargo system of a civil aircraft, belonging to the field of air cargo. The locking tongue is located on the left side of the base, and the locking tongue is hinged with the base; The linkage rod is located in the middle of the locking bolt, and the two ends of the linkage rod are hinged with the locking bolt respectively; the two sides of the linkage rod are provided with long round hole chute, the limit arm is located in the middle of the linkage rod, and the limit pivot arm is respectively connected with the base and the linkage rod Hinged; the unlocking arm is located on the left side of the linkage rod, the middle position of the unlocking arm is provided with an acute angle groove, and the end position is provided with an oblong hole, the acute angle groove structure is in contact with the boss of the linkage rod, and the oblong hole is used for the acute angle of the unlocking arm The groove is disengaged from the structural limit of the linkage rod to provide free travel. The present application solves the problems that the existing similar locking devices cannot simultaneously limit the course, lateral and vertical positions of the container unit, and the outline of the locking device cannot automatically fall below the transmission plane under the contact of the bottom structure of the container unit.

Description

technical field [0001] The present application belongs to the technical field of air cargo, and in particular relates to a multi-directional locking device used for the automatic lifting and lowering of a containerized cargo system of a civil aircraft. Background technique [0002] The locking device is matched with the civil aircraft containerized cargo system, and is usually installed in the standard floor slide rail or in the transmission rolling rod mounting frame. Restriction, the reasonable design of the restricting mechanism can ensure that the container unit is accurately locked at the position required by the freight system, and various loads generated by the container unit are transmitted to the main frame beam of the aircraft through the two-way locking device. [0003] In the related art, the locking device supporting the civil aircraft containerized freight system can only realize the heading and vertical or reverse heading and vertical locking functions at the ...
