A split combined type multi-layer heat insulation assembly fixing device comprises a pin column head which is in a long cylinder shape and used for penetrating through a multi-layer heat insulation assembly, pressing piece clamping grooves for pressing pieces to be embedded are distributed in the surface of the pin column head from top to bottom at equal intervals, and a column head-base connector is arranged at the bottom of the pin column head; the pressing sheets are circular and are provided with opening grooves extending from the circle point to the circumference, the opening grooves can be inserted into the pressing sheet clamping grooves so that the pressing sheets can be fixed to the pin column head, and a plurality of layers of heat insulation assemblies are arranged between every two pressing sheets; the pin base is fixed to the surface of the spacecraft, provided with a base-column head connector and used for being connected with the column head-base connector in a matched mode so that the pin column head can be fixed to the pin base. According to the invention, random combination can be carried out in an inserting and buckling butt joint mode, the state can be flexibly changed by changing the combination mode of the pin base and the column head, a large amount of processing time and cost are saved, and the use efficiency of the product is improved.

    一种分体组合式的多层隔热组件固定装置,包括:销钉柱头,呈长圆柱体状,用于贯穿多层隔热组件,表面由上至下等间距分布有供压片嵌入的压片卡槽,底部设有柱头‑底座接口;压片,为圆形,具有由圆点向圆周延伸的开口槽,该开口槽可插入所述压片卡槽内,使所述压片与销钉柱头固定,每二片压片之间设置多层隔热组件;销钉底座,固定在航天器表面,具有底座‑柱头接口,用于与所述柱头‑底座接口配合连接,使所述销钉柱头固定在在销钉底座上。本发明可以通过插扣对接的方式进行任意组合,通过更改销钉底座和柱头的组合方式灵活地应对更改状态,节省大量加工时间和成本,提高产品的使用效率。
