The invention discloses a life buoy for offshore operation, and relates to the technical field of life buoys. When a traditional life buoy for offshore operation is arranged on the body in a sleeving mode, a stable and impact-resistant buoyancy carrier cannot be provided; the device comprises an outer ring buoyancy body, the inner side of the outer ring buoyancy body is connected with an inner ring buoyancy body through two arc-shaped connecting frames, the outer ring buoyancy body is fixedly connected with the connecting frames, and the inner ring buoyancy body is arranged in second positioning rings symmetrically arranged at the two ends of the connecting frames in a penetrating mode. The inner ring buoyancy body between the adjacent ends of the two connecting frames is a bent section which is inwards concave towards the circle center; the elastic rope loop is arranged between the connecting frame and the inner-ring buoyancy body in a penetrating mode, the elastic rope loop between the bent section and the outer-ring buoyancy body can extend and deform towards one side of the outer-ring buoyancy body under treading of the feet of a person so that the gravity center can be lowered, and meanwhile the section, between the two second positioning rings, of the inner-ring buoyancy body is driven to contract towards the circle center so that the front portion and the rear portion of the chest can be clamped; and the combination stability and the supporting safety of the life buoy for offshore operation and the body are improved.

    本发明公开了海上作业用救生圈,涉及救生圈技术领域。传统海上作业用救生圈在套设在身体上时无法提供一个稳定、抗冲击的浮力载体;本发明包括外圈浮力体,外圈浮力体内侧通过两个呈弧形的连接架连接有内圈浮力体,其中,外圈浮力体与连接架为固定连接,内圈浮力体穿设在连接架两端对称设有的第二定位环内,且两个连接架相邻端之间的内圈浮力体为向圆心内凹的弯曲段;以及穿设于连接架与内圈浮力体之间的弹性绳圈,弯曲段与外圈浮力体之间的弹性绳圈能够在人员脚部的踩踏下向外圈浮力体一侧延展变形来实现降低重心,同时驱动两个第二定位环间的内圈浮力体区段向圆心收缩来夹紧胸腔前、后,增加海上作业用救生圈与身体结合的稳定性以及支撑安全感。
