Description
Technical Field
The utility model relates to the technical field of aircraft structural design, in particular to a counterweight structure suitable for being installed on an aircraft thin-wall structure.
Background
In some cases, the weight is balanced by installing a counterweight structure on a supporting structure (frame and beam) of the aircraft, and most of the supporting structures on the aircraft are thin-wall reinforced structures, so that the supporting structure of the aircraft is protected from being damaged, and the diameters of installing bolts of the counterweight structure are not excessively large. Conventional counterweight structure mounting bolts need to match the thickness of the counterweight structure and are therefore generally longer, as are the diameters of the bolts to meet strength requirements. In summary, a counterweight structure with simple structure, convenient assembly and installation by using short bolts is needed.
Disclosure of Invention
The utility model aims to:
the counterweight structure is simple in structure, convenient to assemble and capable of being installed by using small-diameter bolts.
The technical scheme is as follows:
providing a counterweight structure adapted to be mounted on an aircraft thin-wall structure, comprising a base plate and at least one counterweight plate;
the base plate is provided with a fixed mounting through hole and a counterweight assembly through hole, and is fixedly connected with the thin-wall structure of the airplane through the fixed mounting through hole;
each weight plate is provided with a weight assembly through hole, and the weight plates can be overlapped with the base plate into a whole and are fixed with the base plate into a whole through the bolt assembly and the communicated assembly through holes;
the base plate is fixedly connected with the thin-wall structure of the airplane through a fixed mounting through hole;
the weight plate is positioned on the outer side of the base plate, and the aircraft thin-wall structure is positioned on the inner side of the base plate.
Further, the base plate and at least one weight plate are rectangular plates.
Furthermore, the fixed mounting through holes are annularly and uniformly distributed.
Further, the counterweight assembly through holes are annularly and uniformly distributed.
Further, on the base plate, the fixed mounting through holes and the counterweight assembly through holes are distributed at intervals.
Further, the counter weight assembly through hole is a counter bore and can be embedded into the bolt assembly.
Furthermore, the fixed mounting through holes are circular groove counter bores, and the positions of each counterweight plate corresponding to the fixed mounting through holes are provided with circular through holes.
Further, the bolt component is a short bolt through the long bolt and the counterweight assembly through hole.
The technical effects are as follows:
the utility model has simple structure, easy assembly, block connection mode, small length of the connecting bolt of the counterweight and the supporting structure and low additional bending moment, and can be widely applied to the counterweight design of various aircraft thin-wall structures.
