Through the cooperation of the first rubber sleeve, the second rubber sleeve, the plug-in assembly and the plug-in rod, when the athlete collides with the hurdle during the crossing process, the first rubber sleeve and the second rubber sleeve absorb part of the impact force, thereby reducing the possibility of injury to the athlete. The two cross bars can be quickly separated when hit, reducing interference with the athlete's subsequent movements and helping the athlete to maintain balance and speed. The two ends of the cross bar are easy to reassemble after separation, which facilitates the maintenance and use of the hurdle.

[0022] 3. Through the cooperation of the base assembly, the first rotating shaft and the second rotating shaft, after the training is completed, the first rotating shaft and the second rotating shaft fold the first cross bar and the second cross bar backwards. The hurdle after being disassembled and folded occupies less space, which is convenient for storage in a warehouse or storage area. In addition, the volume of the hurdle after being folded becomes smaller, which is convenient for transportation and storage, reducing damage caused by collision or extrusion and extending the service life of the hurdle.
