The invention belongs to the field of design of matched structures on aircrafts, and particularly relates to a pressing type small force bearing lock for an airplane. And the maintenance covering cap is connected with the machine body structure by using a supporting plate nut, so that the maintenance operation time is prolonged. A lock body seat internally comprises a 3/4 cylindrical cavity and a 1/4 cylindrical solid body, a guide groove and a sliding block movement groove which extend in the axial direction are formed in the side face of the 1/4 cylindrical solid body, an L-shaped movement groove partition plate is arranged between the guide groove and the sliding block movement groove, and a drag hook guide groove is formed in the L-shaped movement groove partition plate; the lock cylinder comprises a 3/4 cylindrical solid body combined with the lock body seat and a 1/4 cylindrical notch, and a lock cylinder guide boss with a locking groove is arranged on the side face of the 1/4 cylindrical notch; a spring connecting structure, a push plate and a guide groove are sequentially arranged on the outer side face, located in the sliding block movement groove, of the sliding block from outside to inside, and the guide groove comprises a clockwise closed-loop movement track and guide groove steps distributed on the movement track and sequentially lowered. The disassembly is convenient and fast, the time in the aircraft covering cap disassembly and assembly process is effectively shortened, and the attendance rate of an aircraft is increased.

    本发明属飞行器上配套结构设计领域,具体涉及一种飞机按压式小型承力锁。维护口盖多使用托板螺母与机体结构进行连接,延长了维护的操作时间。本发明的锁体座内包括3/4圆柱形空腔和1/4圆柱形实体,在1/4圆柱形实体的侧面布置有沿轴向延伸的导向槽和滑块运动槽,两者之间是L形运动槽隔板,其上具有拉钩导向槽;锁芯包括与锁体座结合的3/4圆柱形实体和1/4圆柱形缺口,在1/4圆柱形缺口的侧面上布置有带锁止槽的锁芯导向凸台;滑块在位于滑块运动槽中的外侧面由外向内依次具有弹簧连接结构、推板和导槽,导槽包括沿顺时针闭环的移动轨迹以及分布在移动轨迹上依次降低的导槽台阶。拆卸方便快捷,有效降低飞机口盖拆装过程中的时间,提高飞机的出勤率。
