The invention discloses a bus lifting ring with the emergency brake preventing function. The bus lifting ring comprises a connecting pipe and a lifting ring handle; a rotating shaft is rotatably connected into the connecting pipe; a rotating inner pipe is arranged on the rotating shaft in a sleeving mode; a rotating outer pipe is arranged on the rotating inner pipe in a sleeving mode; two symmetrically-arranged movable grooves are formed in the rotating outer pipe; each of the side wall of the rotating inner pipe and the side wall of the rotating outer pipe is fixedly connected with two symmetrically-arranged connecting belts; the tail ends of the multiple connecting belts are fixedly connected with fixing blocks; and the fixing blocks are fixedly connected to the upper end face of the lifting ring handle. The bus lifting ring is reasonable in structure; the lifting ring is fixed under the action of a movable ball when a bus is braked suddenly by arranging an electrifying wire pipe, the rotating outer pipe, the rotating inner pipe, the movable ball and other structures, support during inertia unbalance is provided for passengers, the wrists of the passengers are prevented from being hurt by the strip-shaped lifting ring, and meanwhile the passengers are prevented from falling down due to unbalance.
