The invention relates to the technical field of aerospace environment laboratories, and discloses a vacuum cabin for aerospace environment simulation. The vacuum cabin comprises a cabin body, an extrusion toothed bar is inserted in the side surface of the cabin body, a bearing plate is fixedly connected to one side, located in the cabin body, of the extrusion toothed bar, a support spring is fixedly connected to one side, close to the inner wall of the cabin body, of the bearing plate, the side face of the extrusion toothed rod is in engaged connection with a bearing wheel, and the lower portion of the bearing wheel is rotationally connected with a centrifugal wheel through a belt; and the side face of a delay screw rod is in sliding connection with an extrusion rod, the side, away from awheel center, of an engagement rod is in engaged connection with a conical screw rod, and the side face of the conical screw rod is in engaged connection with a rotating shaft. According to the vacuumcabin for aerospace environment simulation, through cooperative use of the bearing plate and the bearing wheel, the effect that when a person moves in the simulation vacuum cabin, the person is prevented from generating large extrusion force with the wall of the cabin body due to the too high moving speed, and the person is prevented from being injured is achieved.

    本发明涉及航天环境实验室技术领域,且公开了一种航天环境模拟用真空舱,包括舱体,所述舱体的侧面穿插设置有挤压齿杆,所述挤压齿杆位于舱体内部的一侧固定连接有承接板,所述承接板靠近舱体内壁的一侧固定连接有支撑弹簧,所述挤压齿杆的侧面啮合连接有承接轮,所述承接轮的下方通过皮带转动连接有离心轮,所述延时螺杆的侧面滑动连接有挤压杆,所述啮合杆远离轮心的一侧啮合连接有锥形螺杆,所述锥形螺杆的侧面啮合连接有转轴。该航天环境模拟用真空舱,通过承接板与承接轮的配合使用,从而达到了当人员在模拟真空舱内移动时,避免人员由于移动速度过大而与舱体壁产生较大的挤压力,造成人员受伤的效果。
