Description
Technical field
The invention belongs to sports apparatus field, the retraction type diving springboard using when particularly a kind of three-metre springboard diving is trained.
Background technology
Existing diving is comprised of fore-stock, after-poppet and pedal with three-metre springboard primary structure, and fore-stock and after-poppet are fixed on limit, pond, and pedal is fixed on front and back support.During use, pedal can only vertical tremor, cannot move forward and backward.When three-metre springboard diving training or match, beginner often there will be the scratching pedal phenomenon of botching routines after take-off.Many outstanding sportsmen during to the challenge of limit difficult part, also there will be this scratching pedal phenomenon.Larger to the injury of sportsman's body and mind after scratching pedal, especially the harm of head scratching pedal is larger, even can threaten athletic life.If beginner often scratching pedal cannot high-qualityly complete dive, not only easily cause injury gained in sports, also easily produce mental handicape, give up learning initiative, practice effect is not good.Do not reach like this object of quick grasp diving technology.And the three-metre springboard that existing diving training and competition adopts cannot be accomplished rapid retraction pedal after sportsman's take-off.
Summary of the invention
The object of the present invention is to provide the collide with retraction type diving springboard of pedal of a kind of sportsman of preventing.This springboard is provided with the car that reverses, can be after sportsman's take-off moment retraction pedal, can reach and prevent the collide with object of pedal of sportsman.
Object technical scheme of the present invention is as follows:
The present invention includes pedal, fore-stock, after-poppet, car reverses.Wherein, the car that reverses consists of base and the car body that reverses, base by the front and rear panels that be arranged in parallel, be connected in the top, two ends of front and rear panels two inner sleeves, be connected in the cuboid frame structure that two kerves of the bottom, two ends of front and rear panels form, the car body that reverses by being enclosed within respectively two outer tubes on two inner sleeves, the transverse arm, the symmetrical castor that is connected to two outer tube lower ends and is embedded in corresponding kerve that are connected between the rear end of two outer tubes form; Between the transverse arm of the car body that reverses and the rear plate of base, be connected with spring, the sidepiece of an outer tube is provided with fixing limit adjuster therein, and inner sleeve corresponding to fixing limit adjuster is provided with locating hole; Fore-stock and after-poppet are separately fixed at and reverse on car body, and pedal is fixed on fore-stock and after-poppet, are connected with one end of bottom tube on the header board of car base that reverses, and the other end of bottom tube connects an arm, and arm upper end is connected with light fixture.
In described light fixture, be provided with battery and shot-light, the wire that connects battery and shot-light penetrates arm and is connected with the switch on arm;
Two kerve lower ends of the described car base that reverses are connected by screw and nut with the ground on limit, pond respectively.
Using method of the present invention is: this springboard can be fixed on to limit, pond, promote after-poppet and two front and back supports on outer tube and pedal are advanced to touch header board.Now, fixing limit adjuster pins outer tube automatically.Then, by switch opens shot-light, light beam can accurately be penetrated at pedal front end.
When training diving, instructor station is on fixing limit adjuster side, and when sportsman takeoffs pin while leaving pedal on pedal, coach opens rapidly fixing limit adjuster, and now spring pulls support and pedal on outer tube to reclaim rapidly.When sportsman falls, pedal reclaims, if now player motion error is also collided with less than pedal.For sportsman feels the existence of pedal, can be with reference to the position of light during diving.Because pedal has reclaimed, light is motionless.When sportsman's dive is carried out to technical Analysis, can utilize video camera to shoot with video-corder diving process, then, according to the playback of video slow motion, analyze.During analysis, observe when sportsman moves whether enter light beam district, if sportsman enters light beam district in a certain position of health when falling, explanation can bump to pedal, baulk.By analyzing, while knock-oning under prompting sportsman, note adjusting improvement technology.
The present invention compared with prior art tool has the following advantages:
1, simple in structure, easy to use, this springboard is provided with the car that reverses can make pedal reclaim, and can effectively prevent sportsman's pedal that collides with.The light beam of shot-light can make sportsman distinguish the position of springboard, and after support and pedal reclaim, light is motionless, and sportsman can regard pedal as light beam.Light beam also can help coach to do technical Analysis.
2, with this springboard, carry out three-metre springboard diving training, can avoid adopting traditional springboard exercise drawback of pedal of easily colliding with.The mental handicape that can effectively eliminate sportsman to be afraid of to collide with pedal and produce.
3, adopt the exercise of diving of retraction type diving springboard, can improve practitioner's excitability, excited practitioner's learning interest.Especially the take-off that beginner also can be bold, grasps action fast.When elite challenges limit difficulty, trial that also can be bold.This springboard can meet the needs of popular and professional athlete special training, and it has practical significance to improving three-metre springboard diving training effect.
