The aircraft arresting hook uplock device is characterized in that the rear end of an actuator cylinder body is fixed at the upper ends of a lock plate I and a lock plate II, and the piston rod end of the actuator cylinder body is hinged to the upper end of an upper rocker arm through a pin shaft I; the lower end of the upper rocker arm and the upper end of the lower rocker arm are rotatably connected to a hinge shaft fixed to the lock plate I and the lock plate II, and a positioning protrusion I at the lower end of the upper rocker arm abuts against a positioning protrusion II at the upper end of the lower rocker arm. The lower end of the lower rocker arm is hinged with the upper end of a connecting rod through a pin shaft II; the other end of the tension spring is fixed on a tension spring shaft; the tension spring shaft is fixed on the lock plate I and the lock plate II; the upper end of the lock hook is rotatably connected to a lever shaft fixed to the lock plate I and the lock plate II, and a connecting lug extending out of the upper end of the lock hook is hinged and fixed to the lower end of the connecting rod. The uplock can be kept in a closed state under the condition that a system has no pressure, locking can be achieved in a mechanical mode, and when the actuating cylinder drives unlocking, the lock ring can move up and down within a certain range after being disengaged from the lock hook, and re-locking cannot be caused.
本发明公开了一种飞机拦阻钩上位锁装置，作动筒缸体后端固定在锁板Ⅰ和锁板Ⅱ的上端，其活塞杆端由销轴Ⅰ铰接在上摇臂上端；上摇臂下端和下摇臂上端可旋转地连接在固定在锁板Ⅰ和锁板Ⅱ上的铰接轴上，上摇臂下端的定位突起Ⅰ与下摇臂上端的定位突起Ⅱ抵接在一起；下摇臂下端通过销轴Ⅱ与连杆上端铰接在一起，连杆下端固定拉簧；拉簧另一端固定在拉簧轴上，拉簧轴固定在锁板Ⅰ和锁板Ⅱ上；锁钩上端可旋转地连接在固定在锁板Ⅰ和锁板Ⅱ上的杠杆轴上，其上端伸出的连接耳铰接固定在连杆下端。本发明能够在系统无压力情况下上位锁保持关闭状态，并能够通过机械方式上锁，作动筒驱动开锁时，锁环脱离锁钩后可以上下运动一定范围并不会造成重新上锁。
