The invention discloses a cabin door opening and closing mechanism which comprises a cabin door, a cabin door hinge, a connecting rod 1, a connecting rod 2, a connecting rod 3, a rotary joint, a cabindoor side plate connecting block and other parts. A retractable part 1 is driven to rotate around a pin shaft 4 if a retractable supporting rod 20 moves into a retractable outer cylinder 12 along theaxis of the retractable outer cylinder 12, the connecting rod 1 (7) connected with the retractable part 1 is driven to move while the retractable part rotates, and meanwhile, a connecting rod 2(9), the rotary joint 19, and the connecting rod 3(18) are driven to move; and under the driving of the connecting rod 3(18), the cabin door 16 revolves around the rotation axis of the cabin door hinge 6, and the cabin door is closed. According to the cabin door opening and closing mechanism, part folding and unfolding and cabin door opening and closing can be completed at the same time through one setof executing mechanism, and the cabin door opening and closing mechanism can be used for occasions of landing gear and cabin door combined opening and closing, including aircraft landing gear cabins,and can also be used for other occasions where parts and cabin doors are opened and closed jointly, including aircraft load cabins.

    本发明公开了一种舱门开闭机构,包括舱门、舱门铰链、连杆1、连杆2、连杆3、旋转接头、舱门侧板连接块等零件,若收放撑杆20沿着收放外筒12的轴线向收放外筒12内移动,带动收放零件1绕销轴4旋转,收放零件1旋转的同时带动与其联接的连杆1(7)运动,同时带动连杆2(9)、旋转接头19、连杆3(18)运动,在连杆3(18)的带动下,舱门16绕着舱门铰链6的旋转轴转动,闭合舱门16,本发明的舱门开闭机构能够实现一套执行机构同时完成零件收放与舱门开合,可用于飞机起落架与舱门联合开闭的场合,包括飞机起落架舱,也可用于其它零件与舱门联合开闭的场合,包括飞机载荷舱。
