Adjustable high jump pole

Abstract

The invention discloses an adjustable high jump pole. The adjustable high jump pole comprises two first sleeves, supporting rods slidably penetrate through inner cavities of the first sleeves, secondsleeves are placed on a bearing plate, and a transverse rod is arranged between the two second sleeves; first springs movably sleeve the portions, located in inner cavities of positioning grooves, ofthe outer wall of the transverse rod, one side of each positioning groove is provided with at least eight first slots, balls are movably embedded in inner cavities of the first slots, second springs movably sleeve the portions, located in the inner cavities of the first slots, of one sides of the balls, and elastic ropes are fixedly connected to the other ends of the second sleeves. According to the adjustable high jump pole, through the cooperation of the transverse rod and the second sleeves, a deformation space can be provided for deformation of the transverse rod, pressure from athletes can also be buffered, thus the probability that the transverse rod is broken under pressure is greatly reduced, and the service life of the transverse rod is prolonged accordingly; besides, the elasticropes apply traction force to the slipping second sleeves, and the athletes are prevented from being injured by the crashing transverse rod.

Description

technical field [0001] The invention relates to the field of sports equipment, in particular to an adjustable high jump pole. Background technique [0002] High jump, one of the jumping events of track and field sports. Also called fast jump. It consists of rhythmic run-up, one-foot take-off, vacating the bar and landing. The score is calculated based on the height at which the player successfully crosses the upper edge of the bar and the ranking is determined based on this. High jump sports are then bound to be inseparable from high jump equipment, and high jump equipment needs to constantly adjust the height of the crossbar to exercise or measure the high jump level during training or competition. [0003] However, in the prior art, the crossbar of the high jump device is only placed on the load-bearing parts at both ends, and then the athlete jumps over the crossbar. However, during the high jump, the athlete often presses or touches the crossbar because the position is...

Problems solved by technology

[0003] However, in the prior art, the crossbar of the high jump device is only placed on the load-bearing parts at both ends, and then the athlete jumps over the crossbar. However, during the high jump, the athlete often presses or touches the crossbar because the position is not fully grasped. The crossbar, so that the crossbar will be broken or the crossbar will hit the athlete in the process of falling, and hit the athlete, thus causing injury to the athlete's body
