The invention relates to the technical field of lifesaving in water, in particular to a retractable labor-saving life buoy. The invention aims to provide the retractable labor-saving life buoy, so as to solve the problems that the life buoy is overlarge in occupied area, is not provided with a device for autonomously sending a distress signal, floats on the water surface and greatly consumes the strength of a human body. The invention discloses the retractable labor-saving safety type life buoy which comprises a waterproof tank, a waterproof cavity formed in the waterproof tank and provided with an opening in one side, an anti-collision box slidably connected to the waterproof tank, an anti-collision cavity formed in the anti-collision box and provided with openings in the two sides, and the anti-collision cavity communicates with the waterproof cavity, an expansion box which is connected to the inner wall of the anti-collision box in a sliding mode, a fixed box which is connected to the expansion box in a sliding mode, and an air blowing device which is arranged in the waterproof cavity.

    本发明涉及水中救生技术领域,尤其是涉及一种收缩式省力安全型救生圈。本发明的目的在于提供了一种收缩式省力安全型救生圈,以解决救生圈占地面积过大、未配置自主发出求救信号装置、漂浮在水面上对人体力量消耗极大的问题。本发明公开了收缩式省力安全型救生圈,包括防水箱,设置在所述防水箱内且一侧开口的防水腔,滑动连接在所述防水箱上的防撞箱,设置在所述防撞箱内且两侧开口的防撞腔,所述防撞腔与所述防水腔贯通,滑动连接在所述防撞箱内壁上的膨胀箱,滑动连接在所述膨胀箱上的固定箱,设置在所述防水腔内的鼓气装置。
