Problems solved by technology

At present, the commonly used methods are connection and release based on pyrotechnic devices. Commonly used pyrotechnic connection and release devices include compression seats based on explosive bolts, wrapping tapes based on explosive bolts or pyrotechnic cutters, and pyrotechnic separation. Compression seats for nuts, compression seats based on pyrotechnic cutters, etc. Most of these compression release devices are for one-time use, and the loading procedure is complicated, which makes it difficult to meet the needs of repeated loading on rails

Abstract

The invention discloses a repetitive on-orbit locking mechanism. The mechanism is characterized by comprising a base (1), a turntable (2), a driving connecting rod (3), an L-shaped connecting rod (4),a synchronous connecting rod (5), an unlocking connecting rod A (6), an unlocking connecting rod B (7), an unlocking connecting rod C (8), a supporting seat (9), a supporting connecting rod A (10), asupporting connecting rod B (11), a pressing connecting rod (12), a pressing block 13, a pressing flange 14 and a pressing screw 15; the locking mechanism is high in locking rigidity, large in unlocking force margin, capable of achieving multi-point synchronous pressing and capable of achieving on-orbit repeated pressing.

Description

technical field [0001] The invention relates to a locking mechanism, in particular to a repetitive on-rail locking mechanism. Background technique [0002] In the field of aerospace, the connection and release of payloads and vehicles exists widely, such as stages and stages of multi-stage rockets, satellites and launch vehicles, satellites and spacecraft, solar wings and space vehicles, deployed antennas and space vehicles, and so on. At present, the commonly used methods are connection and release based on pyrotechnic devices. Commonly used pyrotechnic connection and release devices include compression seats based on explosive bolts, wrapping tapes based on explosive bolts or pyrotechnic cutters, and pyrotechnic separation. The compression seat of the nut, the compression seat based on the pyrotechnic cutter, etc., most of these compression release devices are for one-time use, and the loading procedure is complicated, and it is difficult to meet the demand for repeated lo...
