The invention provides a foldable arresting hook mechanism. Folding and unfolding operation of an arresting hook is achieved through movement of a four-bar mechanism. According to the arresting hook mechanism, the arresting hook rocker arm is folded, so that a longer arresting hook length is obtained in a limited arresting hook cabin, the dragging angle is reduced, the impact load during carrier landing is reduced, the arresting effect is improved, meanwhile, the arresting hook mechanism moves the mounting position of the arresting hook backwards, the mounting distance between the arresting hook and an aircraft main part is increased, and the arresting hook is more convenient to mount. And the blocking effect is further improved. The guide pin shaft is arranged in the mechanism, and the connection relation among the small connecting rod, the front rocker arm and the rear rocker arm is controlled by adjusting the left-right position of the guide pin shaft, so that the mechanism adapts to different motion states of hook releasing, downward pressing, buffering and the like of the arresting hook mechanism. In addition, a cabin door of the arresting hook mechanism is a linkage cabin door, a cabin door mechanism does not need to be designed, the arresting hook mechanism is fixedly connected with the rear rocker arm, and ship landing arresting is not affected. The device is simple and compact in structure, stable, reliable and low in cost.

    本发明提供了一种可折叠的拦阻钩机构,通过四连杆机构的运动实现拦阻钩的折叠与展开操纵。该拦阻钩机构通过将拦阻钩摇臂折叠,使得在有限的拦阻钩舱内获得更长的拦阻钩长度,进而减小拖曳角,减小着舰时的冲击载荷,从而改善拦阻效果,与此同时,该拦阻钩机构将拦阻钩的安装位置后移,增大了与飞机主起间的安装距离,进一步改善了拦阻效果。该机构中设有导向销轴,通过导向销轴的左右位置的调节,控制小连杆、前摇臂、后摇臂之间的连接关系,从而适应拦阻钩机构放钩、向下压紧、缓冲等不同的运动状态。此外,拦阻钩机构的舱门为联动舱门,无需设计舱门机构设计,与后摇臂固定连接,且不影响着舰拦阻。本发明结构简单紧凑,稳定可靠,成本较低。
