Abstract

A single-crankshaft fender trim plate slope type snowboarding trainer consists of a front arc-shaped base frame, a rear arc-shaped base frame, a middle slope support, a side slope support, a closed arc gradient plastic plate, a single-crankshaft fixed treading slide plate with pulleys, a rebounding rubber belt, a guiding horn base, an arc-shaped plate slope type slide way, a gantry hanger frame, a sliding suspender belt ring, an elastic safety belt and the like. When a sporter performs training, double feet are locked on a foot shoe taking-off device treading slide plate with a single crankshaft wheel, the sporter performs pedaling with strength to enable the pulleys to incline towards one side and enable rolling wheels at the shaft end to roll towards a side slope, and the belt moves and pulls the rebounding rubber belt. When the body performs lateral movement and falls at a certain angle, the slide plate is controlled with double legs and is gradually turned inward to simulate the rotation radian, then the sporter repeats the actions again in the reverse direction and circularly acts in the horizontal direction to simulate various rotary snowboarding actions on snow and improve the specialized strength capacity.

Description

Single arbor wheel arc plate slope formula Halfpipe training aids

Technical field: the utility model relates to sports movement training apparatus, particularly a kind of Halfpipe revolution project land specialized training apparatus.

Technical background: snowboarding project comprises that parallel large revolution, revolution project are one of sports in winter events, Ye Shi China participates in the medal sport of Winter Olympic Games.The enforcement that snowboarder's straight way, bend in play accelerates unusually, accurately slip control system slides circuit technique and tactics needs superpower specific speed, strength endurance ability to ensure, and these abilities need to be by carry out the training of different step strength under specific technique condition in the dry season training in summer, to break through existing strength capacity limit.Therefore, the improvement of land special ability training method and means is particularly important.How the dry season training phase in conjunction with snow on technology, tactics and by the technical movements cadence of real racetrack project, pedaling the simulated conditions such as amount of power, time, to implement excess load specific strength training be the necessary method means that obtain specific speed, strength endurance ability.External sportsman uses alpine skiing revolution training aids more, but this apparatus designs for double plate structure, and angle of revolution is little.It is shorter that the parallel large revolution project of China's Halfpipe is set up the time, the design of handrail and twin shaft double track horizontal slide is set before the Halfpipe training aids employing training aids of existing research, the shortcoming one of this scheme is established the two or one hand handrail of handrail before being can cause last arm fulcrum, double track horizontal slide the one-sided maximum of leg pedal apart from time dump angle little, and front can not form coasting grade angle, parallel large revolution with real analog veneer skiing, revolution technology has certain gap, do not reach the effect that improves special ability, the 2nd, sky body steel frame construction takes off plate as there is pedaling pin in training process, leg easily drops between the gap of framework, be prone to the danger of card leg, poor stability.

The content of utility model: design a kind of single crank wheel, have closed arc gradient plate, single arbor wheel arc plate slope formula Halfpipe training aids, overcomes the deficiency of existing apparatus.Single arbor wheel arc plate slope formula Halfpipe training aids is by dismountable front arc underframe, rear arc underframe is connected with ramp bracket in pars intermedia is vertical, its two ends state connects the common structural plane with arc and the gradient that forms of side ramp bracket surely, laying has the white plastic plate of limit groove to form the closed arc gradient above, the fixing rolling pulley of two ends of a single oblique crank Z, curved axle recess plane is fixing pedals slide plate with fixing feet footwear the stepping on of device that come off, bottom in the middle of curved axle recess plane hangs pulling force elastic rubber band, the pulling force elastic rubber band other end is through the horn base that is fixed on the double horn degree of lip-rounding in the middle of middle ramp bracket, tiltedly tractive hangs on the underframe face of ramp bracket in pars intermedia, fixing suspension bracket sleeve pipe in the middle of the ramp bracket of side, gallows frame pipe inserts wherein, on gallows frame, wear and hang two slip suspender belt rings, bullet safety belt is drawn in the connection of suspender belt ring.

The utility model operation principle: in the time that sporter uses, upper body is fastened and is drawn bullet to hang people's safety belt, both feet are locked in to step on and pedal slide plate and come off in device, make slide plate to an inclination and axle head scroll wheel is rolled to side slope, the band athletes ' body pulling force elastic rubber band that moves in the same way and stretch, when health lateral movement and while toppling over certain angle, both legs control slide plate inwardly turns gradually, simulation revolution radian, and latex band is stretched to limiting length, the convergent force of latex band stops parallel camber slideway and it is withdrawn into origin-location in the other direction, sporter repeats above action and circulation and does the action of left and right directions again to opposite direction, with the upper veneer revolution of simulation snow skiing exercises, require the quantity of adjusting latex band to increase external resistance load according to obtaining the reverse resistance of pedaling acceleration magnitude, the needed muscular movement system of training limit accelerated motion strength, cardiopulmonary energy supplying system ability, can effectively improve specific strength level, promote the raising of sports achievement.
