A kind of training hurdle based on vibration sensor

Abstract

The invention relates to a training hurdle based on a vibration sensor. The training hurdle comprises a horizontal hurdle body which is fixedly connected with vertical hurdle bodies, and the bottoms of the vertical hurdle bodies are hinged to bottom hurdle bodies; the vibration sensor is arranged in the horizontal hurdle body; the front faces of the lower portions of the vertical hurdle bodies are provided with grooves; one end of each tension spring is fixedly connected with the inner side of the corresponding groove, and the other end of each tension spring is fixedly connected with the corresponding bottom hurdle body; the side faces of the lower portions of the vertical hurdle bodies are provided with positioning units, a movable motor and a screw connected with the motor are arranged in each positioning unit, and the other end of each screw penetrates through the corresponding vertical hurdle body and the corresponding bottom hurdle body. According to the hurdle, by designing the brand new structure, the bottom hurdle bodies can be folded at the moment when a sportsman touches the horizontal hurdle body or the vertical hurdle bodies to enable the hurdle to be automatically toppled over, the toppled hurdle is almost in a straight-line-shaped horizontal state, and therefore the sportsman is effectively prevented from being hurt in the training process.

Description

technical field [0001] The invention relates to the field of sports equipment, in particular to a training hurdle based on a vibration sensor. Background technique [0002] Hurdles is a sport that is very popular among young people, and it is also one of the very important sports competitions in our country. [0003] From the perspective of structure, the hurdles are roughly divided into the topmost horizontal bar, the vertical bar fixedly connected with the horizontal bar and used to adjust the height of the horizontal bar, and the bottom bar used to support the vertical bar. [0004] When the hurdle is placed normally, it roughly presents an "L"-shaped structure when viewed from the side. During the hurdle process, after the athlete accidentally kicks the hurdle down, the hurdle overturns forward, but after the overturned hurdle lands on the horizontal hurdle and the bottom hurdle is vertical, it is still an "L"-shaped structure. The moment the athlete kicks down the hur...

AI Technical Summary

Problems solved by technology

At the moment when the athlete kicks the hurdle, his own center of gravity changes, and the body is in an uncontrollable posture, and then the athlete's lower limbs often collide with the bottom rail, causing injury to the athlete's body
