The invention relates to the technical field of civil aviation and further discloses a self-locking civil aviation safety belt mechanism based on child touch prevention. The mechanism comprises a mounting base, a supporting column is fixedly connected to the middle position of the top of the mounting base; the outer wall of the supporting column is sleeved with a sliding plate. A first spring is arranged between the bottom of the sliding plate and the top of the mounting base; the top of the supporting column is fixedly connected with a connecting rod. The top of the connecting rod is fixedlyconnected with a limiting block; the invention discloses a self-locking civil aviation safety belt mechanism based on child touch prevention. By arranging a clamping block, the sleeve can be limited;the inclined block is of a trapezoid structure, the area of the lower surface of the inclined block is smaller than that of the upper surface of the inclined block, the inclined block of the trapezoidstructure can slide on the upper surface of the limiting block and the upper surface of the sliding block when pressed down, the self-locking phenomenon can be generated when no adult unlocks the child when the child moves upwards, and mistaken touch of the child is prevented.

    本发明涉及民用航空技术领域,且公开了一种基于儿童防触碰自锁紧式民用航空安全带机构,包括安装座,所述安装座的顶部中间位置固定连接有支撑柱,所述支撑柱的外壁套接有滑板,所述滑板的底部和安装座的顶部之间设置有第一弹簧,所述支撑柱的顶部固定连接有连接杆,所述连接杆的顶部固定连接有限位块,该基于儿童防触碰自锁紧式民用航空安全带机构,通过设置卡块可以对套筒进行限位,防止儿童自己解开安全带,所述斜块为“梯”形结构,且下表面面积小于上表面面积,通过设置“梯”形结构的斜块,在下按时可以与限位块和滑块上表面滑动,在向上移动情况下,无成人解锁时会产生自锁现象,防止儿童误触。
