The invention provides a gravity center auxiliary stabilizing teaching aid for ice and snow sports and a teaching method thereof through improvement, and compared with the prior art, the gravity center auxiliary stabilizing teaching aid has the following improvements and advantages:
firstly, the invention adopts a safety self-locking structure and a safety protection structure to synchronously protect athletes: the protective belt is tightly bound on the body of a sportsman by buckling and connecting the male buckle and the female buckle of the sportsman, when a new person walks or initially performs ice and snow sports, and when the sportsman falls down or loses weight due to insufficient skill, the trigger disc moves downwards and triggers the touch switch, the safety self-locking structure and the lifting cylinder can operate simultaneously, the safety self-locking structure can lock the brake disc to enable the driving seat to be in a static state relative to the base, and simultaneously, the lifting cylinder operates to enable the arc-shaped steel bar to drive the protective belt to move upwards, so that the damage of the sportsman due to falling and losing weight can be avoided in time; by adopting the structure, the athlete can be effectively protected when the athlete generates weightlessness, and the situation that the athlete falls down or weightlessness occurs because the skill of a new person is not skillful is effectively avoided; the technical problem that the situation that a new person falls down or loses weight due to insufficient skill cannot be avoided in the prior art is solved.
Secondly, the invention can assist the athlete to carry out air turning training and flower sliding circle training through the motion posture maintaining mechanism; when the athlete conducts the air swivel training, the horizontal posture plate can be used for the athlete to lie on the outer surface of the posture plate, and the tilting cambered surface is used for supporting the back of the athlete, so that the athlete keeps a high-head chest-lifting posture, and the athlete is assisted in keeping a proper posture to conduct the air swivel training; the posture plate is arranged, a coach is not needed to assist the athlete to stabilize the gravity center of the athlete, and the overturn of the posture plate can be completed by the work of the overturn motor, so that the training of the air rotation action of the athlete is assisted.
Thirdly, when the athlete needs to do the flower slip circle training, the driving motor works to drive the screw rod to rotate so as to enable the screw rod to drive the driving plate to move along the length direction of the sliding strip, further, the sliding strip moves along the length direction of the posture plate, the sliding strip extends out of the posture plate to a proper position to adapt to athletes with different heights, and in the process of performing flower sliding circle training, the sliding strip is in a vertical state under the action of the position adjusting structure, then the driving motor operates to enable the movable end of the sliding strip to be abutted against the ice and snow slide way, so that the athlete can carry out the winding around the vertical sliding strip by holding the handle, and when the athlete winds around, in order to achieve the purpose of assisting the athlete in winding, the overturning motor works to drive the mounting cylinder and the attitude plate to rotate, so that the rotating speed of the attitude plate is the same as the winding speed of the athlete, and the athlete is matched with the attitude plate to carry out the florid slip winding training.
Fourthly, the position of posture board can automatic adjustment when the sportsman walks or the slip training on ice and snow slide, and such effect lies in: first, make gesture board and sportsman keep suitable distance, make the sportsman can move in the space that suits, the slide bar of second, lower extreme perk has the rubber buffer layer and can protect sportsman's rear, avoids sportsman to tumble to the rear side and makes its head and ice and snow slide bump and lead to the sportsman to take place great damage.
Fifthly, in the moving process of the driving seat, the locking gear is always meshed with the helical rack, when the athlete is in a weightless state or falls down, the hair plate moves downwards and triggers the touch switch, so that the safety self-locking structure and the lifting cylinder operate simultaneously, specifically, the electric cylinder is pushed to work to drive the sliding plate to move, the sliding plate drives the transmission gear meshed with the tooth socket of the sliding plate to rotate, the transmission shaft rotates, the transmission shaft drives the clamping arm to rotate in the rotating process, the clamping arm drives the clamping plate to rotate, and the two clamping plates rotating relative to each other compress the brake disc, so that the self-locking shaft stops rotating, the transmission gear stops, the driving seat is prevented from being static relative to the base, the driving seat is prevented from continuously sliding along the sliding rail due to inertia, and the athlete is prevented from falling down in time, Damage occurs due to weight loss.
Sixth, the transverse cylinder can push the driving seat to move along the length direction of the sliding rail through the work of the transverse cylinder, so that the driving seat drives the safety protection structure to move, the movement amplitude of the telescopic end of the transverse cylinder can be matched with the walking speed of the athlete, the purpose of synchronous movement of the driving seat and the athlete is achieved, and the force generated by the athlete driving the safety protection structure is reduced; and drive the safety protection structure through the drive seat and remove, can make the guard band drive the sportsman and remove, help new people to practise on ice and snow slide, improved this device's practicality.
