The invention provides a locking mechanism of a symmetrical rotating part. The locking mechanism comprises an upper rotating component, an upper locking hook, a lower rotating component, a lower locking hook, a reset spring, a transverse shaft and a driving actuator cylinder. The upper rotating component and the lower rotating component are the same in structure; the transverse shaft is arranged on the lower rotating component; the lower locking hook is fixed on the transverse shaft; the reset spring is arranged on the transverse shaft and is arranged between the lower locking hook and the right rib of the lower rotating component; a stop nut is arranged at the right end of the transverse shaft; the driving actuator cylinder is arranged on the left side of the transverse shaft; and the upper locking hook is fixed on the upper rotating component at a position corresponding to the lower locking hook. According to the locking mechanism of the symmetrical rotating part, by separating the driving actuator cylinder and the lower locking hook and transverse shaft, the whole mechanism does not need to occupy large structural space, the structure is light, convenient and simple, the structural weight is reduced, and the complexity and riveting workload of an assembly tool are reduced; the cost and the production period can be greatly reduced and the production efficiency is improved.

    本发明提供一种对称转动部件的锁紧机构包括上转动部件、上锁勾、下转动部件、下锁勾、复位弹簧、横轴、驱动作动筒;所述上转动部件与下转动部件结构相同;所述横轴设置在下转动部件上;所述下钩锁固定在横轴上;所述复位弹簧设置在横轴上,且设置在下钩锁与下转动部件右肋之间;所述横轴右端设置有止动螺母;所述驱动作动筒设置在横轴左侧;所述上锁勾固定在下钩锁相对应位置的上转动部件上。本发明提供一种对称转动部件的锁紧机构,该机构通过将驱动作动筒和下锁勾横轴分离使整个机构不需占用较大的结构空间,结构轻便简单,降低了结构重量,减少装配工装的复杂度及铆接工作量,可大幅度降低成本和生产周期提高生产效率。
