The invention provides a rod type compression unlocking device, which relates to the technical field of spaceflight and comprises a mounting seat, a base, a compression rod assembly, a split nut and a clamping rod assembly. In a pressing state, the split nut is used for being folded to form a first internal thread and is in threaded connection with the pressing rod; the clamping rod assembly comprises a first clamping rod, a second clamping rod, a first connecting rod, a second connecting rod, a push-pull pin shaft, a linkage rope and a loosening elastic piece, and in the pressing state, the linkage rope is tensioned so that the first clamping rod and the second clamping rod can clamp the folded split nut; in the unlocking state, the linkage rope is loosened so that the loosening elastic piece can drive the first clamping rod and the second clamping rod to loosen the split nut. When the rod type pressing and unlocking device is in an unlocking state, normal operation of equipment such as a rotating table and a spacecraft cannot be affected; in addition, compared with other compression unlocking devices, the compression unlocking device enables compression connection between the equipment and the spacecraft body to be firmer.

    本发明提供一种杆式压紧解锁装置,涉及航天技术领域,包括安装座、底座、压紧杆组件、分瓣螺母和夹紧杆组件。在压紧状态下,分瓣螺母用于合拢形成第一内螺纹,并与压紧杆螺纹连接;夹紧杆组件包括第一夹紧杆、第二夹紧杆、第一连杆、第二连杆、推拉销轴、联动绳和松开弹性件,在压紧状态下,联动绳张紧以使第一夹紧杆和第二夹紧杆夹紧合拢后的分瓣螺母;在解锁状态下,联动绳松动以使松开弹性件驱动第一夹紧杆和第二夹紧杆松开分瓣螺母。本发明的杆式压紧解锁装置在解锁状态下,不会影响例如旋转台等设备和航天器的正常运行;另外,相比于其他的压紧解锁装置,本发明使得设备与航天器本体之间的压紧连接更为牢固。
