The invention discloses a special built-in frame for an aerospace liquid propeller. The frame comprises a bearing box, a bottom plate is mounted at the bottom end of the bearing box, a first buffer mechanism is mounted on one side of the bearing box and one side of the top end of the bottom plate, and a second buffer mechanism is mounted on the other side of the bearing box and the other side of the top end of the bottom plate; and a connecting mechanism is installed between the bottom end of the bearing box and the top end of the bottom plate, the first buffer machine comprises a first fixingblock installed on one side of the top end of the bottom plate, and a first sleeve is movably installed at the top end of the first fixing block through a pin shaft. A first compression spring playsa role in pulling and supporting a first pressing plate so that a first movable rod moves in a first sleeve, and a second compression spring plays a role in pulling and supporting a second pressing plate so that a second movable rod moves in a second sleeve; and then through the first movable rod and the second movable rod, the two sides of the bearing box achieve a support effect, and the buffering effect is realized.

    本发明公开了一种航空航天液体推进器专用内置架,包括承载箱,承载箱的底端安装有底板,承载箱的一侧与底板的顶端一侧安装有第一缓冲机构,承载箱的另一侧与底板的顶端另一侧安装有第二缓冲机构,承载箱的底端与底板的顶端之间安装有连接机构,第一缓冲机包括安装在底板的顶端一侧的第一固定块,第一固定块的顶端通过销轴活动安装有第一套筒。本发明通过第一压缩弹簧对第一压板起到拉动和支撑的作用,从而使得第一活动杆在第一套筒中移动,通过第二压缩弹簧对第二压板起到拉动和支撑的作用,从而使得第二活动杆在第二套筒中移动,继而通过第一活动杆和第二活动杆承载箱的两边起到支撑作用,实现了缓冲的效果。
