The invention provides a split nut type unlocking and releasing device, and relates to the technical field of aerospace. The split nut type unlocking and releasing device comprises a base, a fixed sleeve, a rotating hoop cylinder, a rotating spring, a limiting rolling piece, a split nut and a trigger; wherein the fixed sleeve is arranged on the base, the rotary hoop cylinder, the fixed sleeve and the split nut are coaxially arranged, and the fixed sleeve is located between the rotary hoop cylinder and the split nut; the rotating spring is arranged between the base and the rotating hoop cylinder; the trigger is connected with the outer wall of the rotary hoop cylinder; a through hole is formed in the side wall of the fixed sleeve, a containing groove is formed in the inner wall of the rotary hoop cylinder, and the limiting rolling piece is movably arranged in the through hole. According to the split nut type unlocking and releasing device, the rotating spring is used for driving the rotating hoop cylinder to rotate so that the limiting rolling piece can move outwards, the split nuts can be separated from one another through the staggered space, and unlocking and releasing of a fixed structure and a separated structure are completed. The device has the advantages of small release impact and high response speed.

    本发明提供了一种分瓣螺母式解锁释放装置,涉及航空航天技术领域。该分瓣螺母式解锁释放装置包括基座、固定套筒、旋转箍筒、转动弹簧、限位滚动件、分瓣螺母和触发器;固定套筒设置在基座上,旋转箍筒、固定套筒和分瓣螺母同轴设置,固定套筒位于旋转箍筒和分瓣螺母之间;转动弹簧设置在基座和旋转箍筒之间;触发器与旋转箍筒的外壁连接;固定套筒的侧壁开设有通孔,旋转箍筒的内壁设置有容置槽,限位滚动件活动设置在通孔中。本发明的分瓣螺母式解锁释放装置,利用转动弹簧带动旋转箍筒转动实现限位滚动件向外移动,错开空间促使分瓣螺母之间相互分离,完成固定结构与分离结构的解锁释放,具有释放冲击小、响应速度快的优点。
