Description

Ice bend exercise auxiliary device Technical Field The invention relates to the technical field of sports training auxiliary equipment, in particular to an on-ice curve training auxiliary device. Background The main technical actions of the pattern skating include sliding, jumping, rotating and gait, the sliding is the root of the pattern skating, good sliding technology is provided, a player can obtain good horizontal speed and stability, and a guarantee is provided for completing the jumping technology with high difficulty. In order to promote the development of the footage of the pattern skating project, the China pattern skating society provides a pattern skating grade test which comprises a sliding step method and a free sliding step method, wherein the assessment of the sliding step method is to urge the athlete to pay attention to the training of the sliding capability. In the basic step method and the first step method, the examination of the crossing steps is more focused, the movement is an important sliding movement of obtaining the speed by curve sliding, but in a beginner, the gravity center is not dared to be moved to the outside due to fear, and the sliding is misused, so that the gravity center of the crossing steps is wrong, and the whole basic sliding technology is affected. Meanwhile, in speed skating and short-road speed skating, the curve technology is the key of final winning, and the inclined angle of the curve is larger than that of the pattern skating, so that the exercise time on the curve is longer, and the inclined angle of the curve at a high speed is also the reason that a beginner causes psychological fear. Moreover, the device of the existing professional practice speed skating curve technology is not suitable for beginners to practice and use, and the practice effect is poor. Therefore, how to provide an on-ice curve training auxiliary device which has a simple structure and is convenient to operate, can eliminate the fear of a beginner and help the beginner to quickly master the curve skill is a problem which needs to be solved by the technical staff in the field. Disclosure of Invention In view of the above, the invention provides the on-ice curve training auxiliary device which has a simple structure and is convenient to operate, the fear of a beginner can be eliminated, and the beginner can be helped to quickly master the curve skills. In order to achieve the above purpose, the present invention adopts the following technical scheme: An on-ice curve exercise assisting device, comprising: the bottom end of the triangular bracket is provided with a spike used for being inserted into ice surface, and the top end of the triangular bracket is fixed with a supporting seat; one end of the middle vertical shaft is fixedly connected with the top end of the supporting seat, and the other end of the middle vertical shaft is sleeved with an inherent bearing; the rotating sleeve is sleeved and fixed on the outer ring of the bearing; The auxiliary pull rod is hinged with the outer wall of the rotary sleeve at one end, and a handle rod is hinged on the wall, close to the other end, of the auxiliary pull rod. Compared with the prior art, the invention discloses an on-ice bend exercise auxiliary device, which is characterized in that when in use, the device is firstly erected at a proper position of a ice rink, a triangular bracket is opened, a spike is inserted into the ice surface to be stably fixed, then a sportsman is accelerated to approach the device, a single hand is used for slightly grasping a hand grip rod, the body is inclined, an auxiliary pull rod is pulled slightly, a small amount of centripetal force is generated, and the auxiliary sliding process is assisted.
