The parachute pack is used for a parachute bay, a stand column is installed in the parachute bay, the parachute pack comprises a surrounding piece and a plurality of traction belts, the surrounding piece is of a barrel-shaped structure, a round hole is formed in the bottom of the surrounding piece, and an opening is formed in the top of the surrounding piece so that the stand column can sequentially penetrate through the round hole and the opening; the multiple traction belts are evenly arranged in the circumferential direction of the surrounding piece, the bottoms of the multiple traction belts are fixedly connected with the surrounding piece, the tops of the multiple traction belts move in the direction close to or away from an opening in the top of the surrounding piece and can move to the first position and the second position, and when the tops of the multiple traction belts move to the first position, the multiple traction belts can move to the second position. A cover body structure with a hole in the middle is formed at the tops of the multiple traction belts and used for sealing the top of the enclosure, and when the tops of the multiple traction belts move to the second position, the tops of the multiple traction belts are arranged at intervals and used for opening the opening in the top of the enclosure; the problem that an existing parachute pack is difficult to adapt to a special-shaped parachute cabin with a stand column in a mounting cavity is solved.
本发明涉及一种降落伞伞包,用于伞舱,伞舱内安装有立柱,包括围幅以及多个牵拉带,围幅为桶状结构,围幅的底部开设有圆孔,围幅的顶部为一开口,以供立柱依次穿过圆孔和开口;多个牵拉带沿围幅周向均匀设置,多个牵拉带的底部与围幅固定连接,多个牵拉带的顶部沿靠近或远离围幅的顶部的开口的方向移动、并可移动至第一位置和第二位置,当多个牵拉带的顶部移动至第一位置时,多个牵拉带的顶部形成一中间开孔的罩体结构,用以封闭围幅的顶部,当多个牵拉带的顶部移动至第二位置时,多个牵拉带的顶部之间间隔设置,用以开启围幅的顶部的开口;解决现有的降落伞伞包难以适应安装空腔内有立柱的异形伞舱的问题。
