The utility model relates to a volleyball block drill rod, which has a base, a telescopic rod, a telescopic rod at the end and a ball scoop. The base is a double bar. The telescopic rod is inserted into the base to rise and fall. The ball scoop is fixed at the end of the telescopic rod at the end of the end. The telescopic rod at the end is bent, there is a horizontal distance between the end and the center line of the base, and there are pits on the surface of the ball scoop, and the base is a circular tower or square tower. The tip part is the sleeve for the expansion rod insertion. There are lifting adjustment bolts on the cylinder body. The weight of the base is larger than the sum of the weight of the expansion rod, the last expansion rod and the ball scoop. The expansion rod has many sections, which bend from bottom to top, and insert each other. There are lifting adjustment bolts between the two adjacent expansion rods. The base is made of cast iron. The expansion rod, the last expansion rod and the ball scoop are made of metal or plastic. Make. The utility model can simulate the setting of the opponent's spike in competition, adjust the height and orientation of the ball, concentrate the movement practice relatively, have strong pertinence, small physical consumption and fast improvement of the movement level, and has simple structure and convenient use.
【技术实现步骤摘要】
排球拦网练习杆
本技术是一种运动训练辅助器械,具体是一种排球拦网练习杆。
技术介绍
在排球比赛中经常出现的一个攻防动作是扣球和拦网,一攻一防在比赛双方总会交替进行。由于拦网防守一般是被动的,难度较大,成功率低,所以为了提高运动水平或者比赛成绩,比赛双方都会进行刻苦训练。通常的拦网练习一般是在教练指导下,将同一个球队队员分为两组或更多组,进行实战化模拟练习,这样一来队员们的运动量就势必增大,体力消耗增加,而针对拦网动作的练习却相对较少,一天的练习下来,队员疲惫不堪,动作水平却未必如意,事倍而功半。所以有必要针对这种情况,在运动器械上进行必要的改进。
技术实现思路
本技术的目的就是针对上述问题提出一种排球拦网练习杆,这种拦网练习杆能够模拟比赛时对方扣球的情形设置,来球高度、方位可调,动作练习相对集中,针对性强,体力消耗小而运动水平提高快,而且结构简单,使用方便。本技术的目的通过如下手段实现:一种排球拦网练习杆,其特征在于它有基座、伸缩杆、末段伸缩杆和承球勺,所述基座为一重砣,伸缩杆插在基座里升降,承球勺固定在末节伸缩杆端头处,末节伸缩杆有弯折,端头与基座中心线间有水平距离,承球勺上表面有凹坑。所述基座为圆塔形或方塔形,塔尖部分为供伸缩杆插入的套筒,筒身上有升降调节螺栓。所述基座的重量大于伸缩杆、末节伸缩杆和承球勺重量之和。所述伸缩杆有多节,自下而上逐节弯细,并相互套插,相邻两节伸缩杆间有升降调节螺栓。所述承球勺的凹坑为与排球一致的曲面坑。所述基座用铸铁制作,伸缩杆、末节伸缩杆和承球勺用金属或者塑料制作。本技术放置在排球网旁,调整高度,让排球静置于承球勺上,固定于球 ...
