The invention belongs to the technical field of aerospace, and discloses an unlocking trigger device. The unlocking triggering device is used for unlocking the split nut device, the split nut device comprises a movable locking rod, the unlocking triggering device comprises a base, a connecting rod assembly, a limiting rope and a rope breaking assembly, the connecting rod assembly comprises a first rod, a second rod and a triggering piece, the first end of the first rod is rotationally connected with the base, and the second end of the first rod is rotationally connected with the limiting rope; the second end of the first rod is rotationally connected with the first end of the second rod, the second end of the second rod is rotationally connected with the first end of the triggering piece, the second end of the triggering piece is rotationally connected with the base, and the limiting rope can apply pulling force to the first rod in the preset direction so that the third end of the triggering piece can abut against the locking rod and lock the split nut device. And the rope breaking assembly is arranged on the base and is configured to fuse or cut off the limiting rope, so that the triggering piece rotates and releases locking of the locking rod and unlocking of the split nut device, the pressing force can be improved, the locking and releasing capacity can be improved, and efficient and reliable unlocking operation can be achieved.

    本发明属于航空航天技术领域,公开了解锁触发装置。该解锁触发装置用于解锁分瓣螺母装置,分瓣螺母装置包括可移动的锁止杆,该解锁触发装置包括基座、连杆组件、限位绳和断绳组件,连杆组件包括第一杆、第二杆和触发件,第一杆的第一端与基座转动连接,第一杆的第二端与第二杆的第一端转动连接,第二杆的第二端与触发件的第一端转动连接,触发件的第二端与基座转动连接,限位绳能沿预设方向对第一杆施加拉力,以使触发件的第三端能够抵压锁止杆,锁止分瓣螺母装置,断绳组件设置在基座上,断绳组件被配置为熔断或切断限位绳,以使触发件转动并解除对锁止杆锁定,分瓣螺母装置解锁,能提高压紧力,提高锁紧释放能力,实现高效、可靠的解锁操作。
