The invention disclose an anti-oversubmergence and self-rescue life buoy. The life buoy comprises a life buoy main body and a self-reaction inflation body connected with the life buoy main body. A conical water plugging groove, a square water inlet cavity, a first water inlet hole, a reaction cavity and a second water inlet hole are sequentially formed in the direction from the interior of the self-reaction inflation body to the life buoy main body, and the water plugging groove communicates with the water inlet cavity; the water inlet cavity is communicated with the reaction cavity through a first water inlet hole, the reaction cavity is communicated with the life buoy body through a second water inlet hole, one-way valves are installed in the first water inlet hole and the second water inlet hole respectively, a water plugging plug is plugged in the water plugging groove, and a threaded rod is coaxially and fixedly connected to the side, located in the water inlet cavity, of the water plugging plug. The threaded rod is sleeved with a sliding plate in sliding connection with the water inlet cavity in a threaded mode. The life buoy has the advantages that the life buoy is suitable for divers with insufficient experience to prevent excessive diving, the excessive diving depth can be adjusted, the life buoy is also suitable for drowning persons who cannot swim or dangerous persons who swim to save themselves, and the life buoy is convenient to carry and use.
