The invention discloses an undercarriage cabin door opening position locking device linked with an undercarriage, which is characterized in that a bevel gear I is fixed at the left end of a rotating shaft of the undercarriage, a bevel gear II meshed with the bevel gear I is fixed at one end of a sleeve, a cylindrical gear I is fixed at the other end of the sleeve, and a shaft of the cylindrical gear I is rotatably fixed on a support frame; the support frame is fixed on a left side wall plate of the undercarriage cabin; a shaft of a cylindrical gear II meshed with the cylindrical gear I is rotatably fixed on the support frame and is parallel to a shaft of the cylindrical gear I; a rack bolt meshed with the cylindrical gear II is opposite to a locking hole formed in a larger lug of the cabin door rotating shaft I; when the undercarriage cabin door is opened in place, the rack bolt is inserted into the locking hole, and when the rack bolt retreats from the locking hole, the undercarriage cabin door is closed. The undercarriage cabin door locking device can be locked after an undercarriage cabin door is opened, and is simple in structure, high in fixing reliability, easy to manufacture and low in cost.
本发明公开了一种与起落架联动的起落架舱门打开位锁定装置,锥齿轮Ⅰ固定在起落架转轴的左端,与锥齿轮Ⅰ相啮合的锥齿轮Ⅱ固定在套筒的一端,套筒的另一端固定有圆柱齿轮Ⅰ,圆柱齿轮Ⅰ的轴可旋转地固定在支撑架上,支撑架固定在起落架舱左侧壁板上;与圆柱齿轮Ⅰ相啮合的圆柱齿轮Ⅱ的轴可旋转地固定在支撑架上且与圆柱齿轮Ⅰ的轴平行;与圆柱齿轮Ⅱ相啮合的齿条插销正对舱门旋转轴Ⅰ的较大凸耳上开有的锁闭孔;当起落架舱门打开到位后,齿条插销插入锁闭孔,当齿条插销退出锁闭孔后,起落架舱门关闭。本发明能够在起落架舱门打开后进行锁定,结构简单,固定可靠性高,易于制造,成本较低。
