Locking mechanism for helicopter tail cabin door
The invention provides a locking mechanism for a tail cabin door of a helicopter, which relates to the field of aviation machinery, and comprises two lock box assemblies respectively mounted on two sides of a tail cabin door frame; the two lock seat assemblies are mounted on the two sides of the tail cabin door respectively; the manual unlocking assembly, the hydraulic unlocking assembly and the swing arm assembly are all installed in the tail cabin, the swing arm assembly comprises a swing arm seat, a first swing arm and a second swing arm, the first swing arm and the second swing arm are hinged to the swing arm seat, and the first swing arm and the second swing arm are in meshing transmission; one lock box assembly and the manual unlocking assembly are in transmission connection with the first swing arm through the transmission assembly, and the other lock box assembly and the hydraulic unlocking assembly are in transmission connection with the second swing arm through the transmission assembly. The locking mechanism has two modes of manual unlocking and hydraulic unlocking, and is convenient and flexible to operate. A lock point formed by the lock box assembly and the lock seat assembly is arranged far away from the axis of the hinged end of the tail cabin door frame and the tail cabin door, high locking torque can be provided, and higher locking safety is achieved.
本发明提供了一种用于直升机尾舱门的锁闭机构，涉及航空机械领域，包括：两个锁盒组件，分别安装在尾舱门门框的两侧上；两个锁座组件，分别安装在尾舱门的两侧上；手动解锁组件、液压解锁组件、摆臂组件，均安装在尾舱内，其中摆臂组件包括摆臂座及铰接在其上的第一摆臂和第二摆臂，第一摆臂和第二摆臂啮合传动；一个锁盒组件和手动解锁组件分别通过传动组件与第一摆臂传动连接，另一个锁盒组件和液压解锁组件分别通过传动组件与第二摆臂传动连接。本锁闭机构具有手动解锁和液压解锁两种方式，操作方便、灵活。锁盒组件和锁座组件构成的锁点远离尾舱门门框和尾舱门的铰接端轴线设置，可提供较高的锁紧力矩，具有更高的锁闭安全性。
