Problems solved by technology

Since the space linkage pressing and releasing mechanism has a dead point, a large unlocking force is required during the unlocking process. In addition, when the locking rod is pressed against the pressing rod, since the pressing area between the locking rod and the pressing rod is small, Therefore, it is difficult to withstand the unlocking of heavy load conditions

Abstract

The invention discloses a star-arrow adapter for multi-point pressing and synchronous unlocking, characterized by a pressing rod cover plate (1), a pressing nut (2), a pressing flange (3), a pressingrod (4), a pressing connecting rod (5), a supporting connecting rod A (6), a supporting connecting rod B (7), an unlocking connecting rod (8), an unlocking sliding block (9), an unlocking spring (10),a pressing base (11), a mounting base plate (12), a linkage rod (13), an L-shaped connecting rod (14), a locking pin connecting rod (15), an unlocking pin (16), a pin pulling spring (17), an unlocking pin shell (18), a pin puller (19), a separation guide cylinder (20), a separation guide rod (21), a separation top cover (22) and a separation spring (23). The star-arrow adapter is compact in appearance, strong in compatibility, high in locking rigidity, low in unlocking impact, pollution-free and reusable.

Description

technical field [0001] The invention relates to a star-arrow adapter, in particular to a star-arrow adapter with multi-point pressing and synchronous unlocking. 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. Currently, the methods used 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., the common feature of these compression release devices is the bearing connection force. In order to ensure the connection rigidity, th...
