Abstract

A wind-resistant cross country skiing special strength simulation trainer comprises a steel body frame, a transverse shaft sleeve, a through shaft, one-way rotary gear flywheels, a large single belt groove wheel, a small groove flywheel, wind wheel blades, flexible belts with teeth, ski sticks, bottom pulleys, elastic rubber belts, movable pulley sets and the like. During training, an athlete stands on a fixing plate of the frame, two arms support the ski sticks to simulate technical actions of using two arms to support the sticks in the free and traditional cross country skiing process; the wind wheel blades are pulled to generate high-speed and rotary airflow resistance to react on the two arms of the athlete, and the strength of using the two arms to simultaneously support the sticks and using a single arm to support one stick as well as the velocity can be improved with the repeated actions.

Description

Wind trainer type cross-country skiing specific strength simulation trainer

Technical field: the utility model relates to cross-country skiing training apparatus, the particularly exercising device of a kind of land special ability.

Technical background: cross-country skiing is one of winter sports project, sports cross country racer needs very strong special ability as, stamina of speed and strength endurance, and cross country racer is sliding fast on snowfield, need to be under rational technical movements by both arms or the racking ski pole replacing promote health and advance, want to create better achievement, stamina of speed and the strength endurance effect of only on snow, training both arms and both legs racking and pedaling are bad, and general motion person need to use specialized training equipment training to improve this ability on land.The exercising device that cross country racer uses at present has rubber bar training aids and the dynamo-electric training aids of magnetic, the sources of resistance that these two kinds of exercising devices produce is the elasticity of rubber bar and the magnetic field electromagnetic quantities that magnetic electromechanics produces at electric current, the former pulls the quantity of rubber bar to increase resistance by increasing both arms, the latter increases resistance by strengthening electric current, after the latter's shortcoming is resistance increment, athletic speed of actions slows down, thereby affect the raising of stamina of speed, and both only can make the elongation training raising arm strength of both arms, rather than moving with the support twelve Earthly Branches of ski pole, training improves arm strength, affect mode of work-doing, training effect is bad.

Utility model content: overcome the deficiencies in the prior art, design and a kind ofly with sportsman's both arms, by the racking of ski pole, promote the apparatus that health advances, and the moving wind trainer type cross-country skiing specific strength simulation trainer that drives the resistance that air blade rotation produces of the support motion of ski pole.Wind trainer type cross-country skiing specific strength simulation trainer has a steel body framework, the front central post of framework bottom is transverse axis cover fixedly, in axle sleeve, pass an axis, its two ends is through the retaining frame and the embedded bearing that are fixed on underframe edge, fix respectively the gear flywheel of toothed single direction rotation, in the middle of axis, fix a large single belt sheave, on the axis left end head stretching out in the bottom bracket axle fixing with being fixed on rearward end frame central post 2 upper ends fixing sulculus flywheel with V-belt around being connected, the nested wind wheel axle sleeve of right-hand member head of axis, the spoke of 6 wind wheel blades is uniformly distributed and is fixed in the above, with the soft belt lower end of teeth, hang over the pulley front end of ski pole bottom, the gear flywheel of single direction rotation is walked around in centre, walk around again the upper lower sheave with two running blocks of elastic rubber band traction, upper end hangs on steel body framework forearm.

Utility model operation principle: both arms support ski pole during training athlete, stand on framework fixed head, ski pole draws forward cane, the convergent force of elastic rubber band is withdrawn into leg front position by the soft belt of teeth and stops falling, ski pole bottom pulley supports ground, then the both arms racking of exerting oneself is moving to back brace sliding, pull the soft belt with teeth to move backward, the now tooth of the gear flywheel of the teeth of soft belt and single direction rotation engagement makes its rotation, simultaneously large single belt sheave rotates the small grooved wheel high speed rotating driving on bottom bracket axle, make wind wheel blade turn produce gas-flow resistance, react on athletic both arms, circulation perseveration, improve strength ability and speed that both arms support cane and single armed support cane simultaneously.

The utility model sportsman can simulate free style and the traditional type cross-country both arms support cane ability of skiing on land with it.Strength endurance ability improves swimming exercise achievement.Apparatus structure is simple, and usage space is little, easy to use.
