The invention provides a fixing mechanism and a spacecraft. The fixing mechanism comprises a rack; the mounting frame is connected with the rack in a sliding manner; the locking mechanism is embeddedin the mounting frame or the rack and comprises a locking strip, a locking block, a locking block and a locking block; the limiting block is connected to the locking bar and located between the two ends of the locking bar, one end of the locking bar can move in the axial direction of the locking bar and extrude the limiting block, and the limiting block generates displacement in the radial direction of the locking bar, so that the locking bar and the limiting block abut against the mounting frame and the rack correspondingly, and locking of the mounting frame and the rack is achieved. According to the fixing mechanism, when the mounting frame needs to be fixed to the rack, the locking mechanism abuts against and is fixed to the mounting frame and the rack at the same time, the mounting frame is fixed to the rack, and the locking mechanism is easy to operate. And meanwhile, the locking mechanism is embedded in the mounting frame or the rack, so that no extra space is occupied, and meanwhile, the mechanical environment condition of the spacecraft in the ascending period and the ergonomic design requirement of an astronaut system can be met.
本发明提出了一种固定机构和航天器,固定机构包括:机架;以及安装架,与机架滑动连接;锁紧机构,锁紧机构嵌设于安装架或机架内,锁紧机构包括:锁条;以及限位块,限位块连接在锁条上且位于锁条两端之间,其中,锁条的一端能沿锁条的轴向移动并挤压限位块,限位块在锁条的径向产生位移,以使锁条和限位块分别与安装架和机架抵靠,实现安装架与机架的锁紧。本发明提供的固定机构,在安装架需要固定在机架上时,锁紧机构同时和安装架以及机架抵靠并固定,实现安装架在机架上的固定,锁紧机构操作简单。同时由于锁紧机构嵌设在安装架或机架内,不会占用额外的空间,同时能够满足航天器上行期间力学环境条件以及航天员系统工效学设计要求。
