Landing gear cabin door locking mechanism
The invention provides an undercarriage cabin door locking mechanism, and belongs to the technical field of undercarriages, the undercarriage cabin door locking mechanism comprises a support mounted on an aircraft body, a buckle mounted on a cabin door, and a locking mechanism mounted on the support and matched with the buckle, the locking mechanism comprises an explosive bolt, and the explosive bolt is connected with the buckle. One end of the explosive bolt is a threaded end, and the other end of the explosive bolt is a plugging end; the threaded end penetrates through the first through hole of the support and is installed on the support through a nut and a gasket. The blocking end is arranged in the second through hole of the buckle, and the blocking end is used for blocking the second through hole. When the cabin door is locked, the height position of the explosive bolt is adjusted, and it is guaranteed that the cabin door is in tight fit with a machine body in the closed and locked state. And meanwhile, dual-redundancy locking is arranged for cabin door locking.
本发明提供了一种起落架舱门锁紧机构，属于飞机起落架技术领域，该起落架舱门锁紧机构包括安装在飞机机体上的支架、安装在舱门上的卡扣，以及安装在所述支架上并与所述卡扣相配合的锁紧机构，所述锁紧机构包括爆炸螺栓，所述爆炸螺栓的一端为螺纹端，所述爆炸螺栓的另一端为封堵端；所述螺纹端穿过所述支架的第一通孔，并通过螺母和垫片安装在所述支架上；所述封堵端设置在所述卡扣的第二通孔内，且所述封堵端用于将第二通孔封堵。本发明通过在舱门上锁时调整爆炸螺栓的高低位置，保证舱门在收上上锁状态与机体之间严丝合缝。同时为舱门上锁设置了双余度地锁定。
