The invention discloses a safety hurdle, which solves the problem that existing conventional device is liable to make people stumbled and injured. The safety hurdle is characterized in that a cross rod is of a middle split structure and is divided into a right half cross rod and a left half cross rod; an end shaft is arranged at the upper end of each telescopic rod and assembled with a bearing, and the most end part of each telescopic rod is positioned by an inner and outer elastic check ring; a limiting block is arranged on the side surface of the top of each telescopic rod; a rotating sleeveis arranged on the outer circle of each bearing, a rectangular short pipe is connected to each rotating sleeve, and a right half cross rod or a left half cross rod is arranged in each rectangular short pipe; one end of a reset spring is connected with the corresponding rectangular short pipe, and the other end is fixed to the upper end of the corresponding telescopic rod. The cross rod of the hurdle is separated from the middle; when an athlete touches the half cross rod on one side due to various reasons, the half cross rod rotates around a stand column on the side and automatically swings to avoid, the half cross rod on the other side still keeps a competition state, and after the athlete touches the half cross rod, the swung half cross rod naturally resets under the action of attraction force of the reset spring or a magnet, and manual intervention is not needed. The learning and training effects of athletes, especially beginners, can be improved, and the athletes can be protected.
