The invention discloses a locking block type rotary hinge locking device which comprises a male hinge, a female hinge, a driving element, a locking block, a locking block shaft, a leaf spring and a main shaft. The male hinge is connected with the female hinge through the main shaft. The driving element provides driving force for hinge unfolding. The locking block is connected with the male hinge through the locking block shaft, the locking block is pressed on the transition face of the female hinge through the leaf spring, the locking block swings along the transition face till the male hinge is limited by the female hinge structure in a hard mode, and self-locking is completed. The device is small in size, high in repeated locking precision, high in rigidity and light in weight.

    本发明公开了一种锁块式回转铰链锁紧装置,包括公铰、母铰、驱动元件、锁块、锁块轴、片簧及主轴;公铰通过主轴和母铰连接,驱动元件为铰链展开提供驱动力;锁块通过锁块轴与公铰相连,片簧将锁块压在母铰的过渡面上,锁块沿所述过渡面摆动直至公铰由母铰结构硬限位,完成自锁。本发明体积小,重复锁紧精度高,刚度高,重量轻。
