The invention belongs to the technical field of helicopter comprehensive guarantee, and particularly relates to a mooring ring assembly with a swing limiting function. A common mooring ring has a non-detachable annular structure form or a detachable threaded installation structure form which is fixedly installed on a helicopter, the mooring ring can swing at will, the problem that the surface of a helicopter body is rubbed and collided is caused, the appearance of the helicopter is affected, and corrosion is prone to being generated. The device comprises a threaded sleeve installed on a machine body, a threaded rod penetrates through the threaded sleeve and is rotationally installed, the threaded rod is sleeved with a limiting sleeve rotating synchronously, and a single fork lug at the outer end of the threaded rod and double fork lugs of a ring body are rotationally installed; the limiting sleeve is of a sleeve structure with an oval opening, the end face, facing the ring body, of the limiting sleeve is provided with a relative limiting plane and an opposite arc-shaped face, and the ring body is limited to make contact with the machine body through the height of the limiting plane. The structure is simple, the manufacturing difficulty is small, the purpose of swing limiting is effectively achieved through the characteristics of the arc-shaped opening, and the anti-collision effect is reliable.
本发明属于直升机综合保障技术领域,具体涉及一种具有摆动限位功能的系留环组件。常见的系留环有固定安装到直升机上不可拆卸的环形结构形式或者可拆卸的螺纹安装结构形式,系留环可任意摆动,导致摩擦磕碰机体表面的问题,影响直升机的外观、容易产生锈蚀。本发明包括安装在机体上的螺套,穿过螺套转动地安装有螺杆,在螺杆上套装有同步转动的限位套,螺杆外端的单叉耳与环体的双叉耳可转动地安装;所述限位套为具有椭圆形开口的套筒结构,在面对环体的端面上具有相对限位平面和相对的弧形面,通过限位平面的高度限制环体接触到机体。结构简单、制造难度小,通过弧形开口的特性有效实现了摆动限位的目的,防磕碰效果可靠。
