Description

Javelin thrower's special strength exerciser

Technical field: the utility model relates to sports movement training apparatus, particularly a kind of javelin thrower's specific strength simulation trainer.

Background technology: the javelin project is the sports events that technology, speed strength ability are combined closely, and the training of the specific technique of special shape (angle of shot), throwing strength and release speed becomes the main means that improve sports achievement.Theoretical research and training practice prove that all the special assistive device training of utilization is effective to raising javelin thrower specific technique, speed strength ability training, may reach following purpose: the one, special apparatus can carry out repeated technique drill, the training of excess load strength, can promote required muscle group (arm, shoulder, chest, the back of the body) the strength ability of throwing, the velocity level who shortens technology shaping time, raising muscle strength is effective.The 2nd, the technology of special apparatus, strength building can obtain the digital quantization data of training process, the effect that coach, sportsman's intuitive analysis are judged, trained and the present situation of level of skill, and special apparatus can be accomplished to want according to reason to ask and control training.In the high country of javelin athletics event level, the control training that the advanced computer digital of utilization combines with the specialized training apparatus, simulated training are on a large scale.And the athletic specific strength training of China carries out with coach's experience, most strength building apparatuses that adopt general fitness trainings, this apparatus can not reach the training requirement of javelin thrower's specialized movement muscle group, address this problem become essential.

The content of utility model: overcome the deficiencies in the prior art, design a kind of simple in structure, easy to use, cost is low, floor space is little, working stability is reliable, javelin thrower's special strength exerciser it have one to have the javelin track bath hoists that hangs fixed arm, the track bath hoists is a square tube, there is hold-down nut upper end in it, fluctuating orbit is equipped with in the lower end, leading screw is housed in its pipe to be cooperated with hold-down nut, rotary handle is equipped with in the leading screw lower end, the short outer arm in the bottom of fluctuating orbit has a υ type clamp, blocking javelin gives and slides suspended rail and be fixed on the clamp, the screw buckle that javelin gives the rear end of the screw buckle that slides suspended rail front end inner arm and gravity javelin is connected, javelin flight guiding cable wire gives the centre of sliding suspended rail and gravity javelin from javelin and passes, one end is locked in javelin and gives the rear end of sliding suspended rail, the other end passes the center of plate from the javelin bump, walk around the javelin bump pulley of plate back is hung with the cable traction pouring weight, javelin gives sliding and hangs with two standard javelin suspended and guided rings on the suspended rail, the standard javelin hangs the cable wire upper end and is connected on the standard javelin suspended and guided ring, the lower end ties up to the stage casing of standard javelin, in the front end of standard javelin, projection velocity is installed, the angular light electric switch, lead gives sliding to draw the suspended rail endoporus from gravity javelin and javelin and is connected to projection velocity, on the angular display unit, bump signal transducting wire one end connects javelin impact quantity sensor holding wire, the other end connects projection velocity, on the interface of angular display unit, angle of shot display sensor is installed on the wall on connecting portion opposite that standard hangs javelin suspension cord and gravity javelin.The utility model is owing to can make the repetition training of sportsman at the enterprising column criterion javelin of apparatus, weight javelin, each back javelin of throwing can return original position automatically, but the function with repeat techniques, the training of excess load strength can effectively improve the required muscle group of javelin thrower (arm, shoulder, chest, the back of the body) strength, velocity level.Can make technology, the strength data visualization of training process, the data of training process can be done objectively the training effect and estimate.For coach, sportsman's intuitive analysis are judged, the effect and the level of skill of training are offered help, and the instrument condition of necessary research means is provided for sentific training.Solve better javelin thrower's supplemental training and winter training problem.Can promote the quick raising of sports achievement.
