The invention relates to a recoverable unlocking bracket for a large-aperture space remote sensing camera, which is characterized in that in a locking state, two explosive bolts respectively penetrate through central holes of an upper pressing block and a conical block and then are connected with an upper section and a lower section of a threaded connecting cylinder, and four wedge blocks are uniformly distributed along the periphery of the threaded connecting cylinder; two wedge-shaped grooves in the wedge block are matched with a first conical boss of the upper support and a second conical boss of the lower support respectively, an annular spring is arranged in a rectangular groove, a plate spring penetrates through a through hole of the wedge block and a rectangular hole of the upper pressing block, then the lower end of the plate spring is hooked on the annular groove of the lower support, and the upper end of the plate spring is fixed to the upper pressing block. And the explosive bolt is detonated and unlocked, the wedge-shaped groove is separated from the conical boss, the conical block is withdrawn, and the four wedge blocks are recovered together and clamp the threaded connecting cylinder. After unlocking, all the free structural parts in the support are restrained and recycled, the risk that the support is stuck due to irregular movement of the free structural parts or the free structural parts move to the outside of the support to become redundant objects is eliminated, and meanwhile the requirement for the large movement distance after the support is unlocked can be met.
本发明涉及一种大口径空间遥感相机可回收解锁支架,在锁定状态下,两个爆炸螺栓分别穿过上压块和锥形块的中心孔后与螺纹连接筒的上段和下段连接,四个楔块沿螺纹连接筒的四周圆周均布,楔块上的两个楔形槽分别与上支架第一圆锥凸台和下支架第二圆锥凸台配合,矩形槽安装放置环形弹簧,板簧穿过楔块的通孔和上压块的矩形孔后下端勾挂在下支架环形槽上,板簧上端与上压块固定;爆炸螺栓起爆解锁,楔形槽与圆锥凸台脱离,锥形块被退出,四个楔块回收到一起并夹紧螺纹连接筒。解锁后支架内部所有自由结构件都被约束回收,消除了自由结构件无规则运动导致支架卡死或自由结构件运动到支架外部成为多余物的风险,同时可满足支架解锁后大运动距离的要求。
