The invention relates to a manual self-locking structure and a hood opening and closing mechanism provided with the same. The self-locking structure comprises an unlocking rod assembly, a locking block and a mounting plate. The mounting plate is fixed on a main opening and closing mechanism body; and a locking groove is formed in an opening and closing wing limiting baffle of the opening and closing mechanism. The unlocking rod assembly is rotationally mounted on the mounting plate; the locking block is movably connected with the unlocking rod assembly, the unlocking rod assembly matches the locking block to form a mechanical dead point when rotating, and the unlocking rod assembly rotates forwards and backwards to drive the locking block to bypass the mechanical dead point forwards and backwards to complete front-back linear motion, so that the locking block is inserted into the locking groove to achieve locking or separating from the locking groove to achieve unlocking. The manual self-locking structure is simple in overall structure and low in cost; the unlocking and locking functions of the hood opening and closing mechanism can be achieved by manually operating the unlocking rod to rotate; the reliability of the unlocking or locking function of the opening and closing mechanism can be effectively guaranteed through the self-locking characteristic of the hood opening and closing mechanism, so that the safety and stability of a rail vehicle in the running process are improved.

    本发明涉及一种手动自锁结构及安装有该自锁结构的头罩开闭机构,自锁结构包括解锁杆组件、锁块及安装板,所述安装板固定在开闭机构主体上,在开闭机构的开闭翼限位挡板上设置有止锁槽,所述解锁杆组件转动安装在安装板上,所述锁块与解锁杆组件活动连接,所述解锁杆组件旋转时与锁块配合形成机械死点,所述解锁杆组件正反向旋转带动锁块正反向绕过机械死点完成前后直线运动,使锁块插入止锁槽实现锁闭或脱离止锁槽实现解锁。本发明整体结构简单,成本低,通过人工手动操作解锁杆旋转即可实现头罩开闭机构的解锁与锁闭功能,并且通过自身的自锁特性可有效保证开闭机构解锁或锁闭功能的可靠性,提升了轨道车辆运行过程中的安全性与稳定性。
