The invention belongs to the technical field of railway vehicle opening and closing mechanisms, and particularly relates to an opening and closing mechanism for a railway vehicle, which comprises a support, a locking gear, an opening and closing wing rotating shaft gear, an opening and closing wing rotating shaft and an unlocking rod, the opening and closing wing rotating shaft is symmetrically mounted on the front side of the support, the opening and closing wing rotating shaft gear is mounted on the opening and closing wing rotating shaft, and the unlocking rod is mounted on the front side of the opening and closing wing rotating shaft. A locking gear is mounted at the upper part of the unlocking rod, and the locking gear and the opening and closing wing rotating shaft gear are mounted in a meshing manner. Two concave blocks are arranged on the lower portion of the opening and closing wing rotating shaft gear, two bosses are arranged on the lower portion of the locking gear, the locking gear on the upper portions of the bosses is of an empty tooth structure, and meshing teeth are arranged between the empty tooth structures. Self-locking can be achieved, the unlocking and locking functions of the opening and closing mechanism can be achieved by manually operating the unlocking rod to rotate, the reliability of the unlocking and locking functions of the opening and closing mechanism can be effectively guaranteed through self-locking cooperation of the boss and the concave block, and normal work of the opening and closing mechanism can still be effectively guaranteed in the non-electricity and non-gas state.
本发明属于轨道车辆开闭机构技术领域,特别是涉及一种轨道车辆用开闭机构,包括支架、锁闭齿轮、开闭翼转轴齿轮、开闭翼转轴、解锁杆,开闭翼转轴对称安装在支架前侧,开闭翼转轴上安装有开闭翼转轴齿轮,开闭翼转轴前侧安装有解锁杆,解锁杆上部安装有锁闭齿轮,锁闭齿轮和开闭翼转轴齿轮啮合安装。开闭翼转轴齿轮下部设有两个凹块,锁闭齿轮下部设有两个凸台,凸台上部的锁闭齿轮为空齿结构,空齿结构之间设有啮合齿。本发明为可实现自锁,通过人工手动操作解锁杆旋转即可实现开闭机构的解锁和锁闭功能,通过凸台和凹块的自锁配合可有效保证开闭机构解锁和锁闭功能的可靠性,在无电无气状态下仍可有效保证开闭机构的正常工作。
