Miniature unfolding mechanism applied to space mesh antenna

The invention provides a miniature unfolding mechanism applied to a space mesh antenna. The mechanism comprises a connecting block, a first gear arm, a second gear arm, a gear shaft and a V-shaped spring. The first gear arm is fixedly installed at one end of a linkage block through the gear shaft, the second gear arm is fixedly connected to the other end of the linkage block through the gear shaft, one end of the V-shaped spring is fixedly installed on the first gear arm through a pressure spring screw, and the other end of the V-shaped spring is fixedly installed on the second gear arm through the pressure spring screw. Technical problems that an existing one-dimensional unfolding mechanism is too high in machining cost and large in assembling difficulty, is not synchronous in unfolding process and not high in product reliability, and is high in batch use risk in large-scale production are solved. 本发明提供了一种应用于空间网状天线的微型展开机构，包括联块、一号齿轮臂、二号齿轮臂、齿轮轴和V型簧，一号齿轮臂通过齿轮轴固定安装至联块一端，二号齿轮臂通过齿轮轴固定连接至联块另一端，V型簧一端通过压簧螺钉固定安装至一号齿轮臂
