Description

Aircraft packing box side by side connection structure Technical Field The invention relates to the technical field of aircraft packaging, in particular to a side-by-side connection structure of aircraft packaging boxes. Background At present, the transport efficiency of the aircraft packing box is often improved through a parallel connection mode of two packing boxes in the transport process. In order to ensure that the two side-by-side packing boxes do not tip over or fall due to inertial load transportation, reliable and convenient means are needed to connect the two packing boxes. The conventional side-by-side connecting assembly has higher requirements on the height difference and the distance between two packing boxes, and in actual operation, the situation that the placement surface is uneven (the height difference is more than 5 mm) is often encountered, so that the side-by-side connecting assembly cannot be installed. For this reason, it is often necessary to try to level the two packages to the same level (height difference <5 mm) and hoist them to a fixed pitch. This brings a lot of extra work to the shipping work of the package. Disclosure of Invention The invention aims to provide a side-by-side connection structure suitable for aircraft packaging boxes. In order to achieve the above object, the present invention provides an aircraft packaging box side-by-side connection structure, comprising: the two connecting seats are respectively arranged on the two aircraft packaging boxes; The two connecting pieces can be respectively arranged on the two connecting seats in a vertical rotation mode, stud sections are arranged on each connecting piece, the stud sections of the two connecting pieces are arranged oppositely at intervals, the two opposite stud sections are connected through a threaded sleeve, and the distance between the two opposite stud sections can be adjusted through rotating the threaded sleeve. Optionally, the connecting piece is an L-shaped column and comprises a stud section and a connecting section, and the stud section and the connecting section are vertically arranged; the connecting seat is provided with a connecting hole, and the connecting section can vertically rotate and penetrate through the connecting hole. Optionally, a step area is arranged on the inner side of the connecting section, the surface of the step area is an arc surface, the length of the step area is larger than the axial length of the connecting hole, and when the threaded sleeve is locked with the two opposite stud sections, the arc surface of the step area is matched with the connecting hole.
