    TRAINING AID FOR POLE VAULT Field of the Invention The present invention belongs to the technical field of sports fitness equipment, and particularly relates to a training aid for pole vault.
    Background of the Invention Pole vault is the most complex event in the track and field sports and has the highest requirement for the comprehensive physical quality of athletes, and it requires excellent speed quality, strong explosive power, and good physical coordination and flexibility. Generally, an excellent pole vault athlete needs eight to ten years of professional training to achieve a high sports level.
    From the aspect of action skills: the action essentials of pole vault comprise four parts: pole holding run-up, pole insertion take-off, inverted crossing and landing, wherein the “inverted crossing” skill is the key and difficult point, and the “inverted crossing” skill may be divided into four parts: pole pressing and suspense, pull-up tuck, inverted push, and turn crossing. Therefore, years of professional training is usually required to master these action skills.
    The inventors believe that in the conventional training process, the learning, mastering and promotion of the “inverted crossing” skill require a long process, for example, in a 90-minute “inverted crossing” skill training session, athletes can complete about 20-30 times of action skill exercises, but a standard action cannot be necessarily made in every exercise. The training effect of the “inverted crossing” skill is also affected by the factors such as “run-up” and “take-off”. For beginners and advanced athletes, it is commendable to make 2-3 perfect actions in a training class, so the training efficiency is low.
    At the same time, in order to obtain sufficient horizontal kinetic energy for “inverted crossing”, the athlete usually has to run at a very high speed with a pole, which consumes a lot of physical energy, so that the main focus cannot be concentrated on the exercise of skills.
    Summary of the Invention An objective of the present invention is to overcome the deficiencies of the prior art, and to provide a training aid for pole vault, which can provide run-up power for athlete's pole vault training, save the action consumption before take-off, save the athlete's physical strength, help the athlete to concentrate on crossing, and improve the level of the athlete's pole vault.
    In order to achieve the above object, the present invention adopts the following technical solution: a training aid for pole vault, including a base and a pulley arranged on an upper surface of the base, wherein the pulley is capable of performing reciprocating linear movement along the base, a slide rail is arranged on the upper surface of the base, and the slide rail is used with the pulley to guide the movement of the pulley.
    A cushion is arranged at one end of the base, and a high jump stand is arranged at the end of the cushion close to the base; A vaulting box structure is mounted on the side of the upper surface of the pulley close to the cushion, the vaulting box structure includes a rotating shaft fixedly arranged on the upper surface of the pulley, the axis of the rotating shaft is horizontal and perpendicular to the moving direction of the pulley, a swivel is sleeved outside the rotating shaft, a pole sleeve is fixedly connected to an outer surface of the swivel, and a pole is inserted into the pole sleeve.
    With the combination of the base, the pulley and the slide rail, the pulley can be used to provide run-up power for an athlete, so that the athlete has a certain initial speed before arriving at the cross bar, and the athlete's physical loss is reduced; with the vaulting box structure, the pole is inserted into the pole sleeve, and the pole can rotate along the rotating shaft, which can reduce the process of pressing the pole and inserting it into a pole vault box by the athlete, and reduce the athlete's physical loss.
    Working principle: the pulley moves to the end away from the cushion to reset, and the athlete stands at the upper part of the pulley, with two hands holding the pole; The pulley is started to move along the slide rail to the high jump stand, and theathlete obtains an initial speed during the movement of the pulley to shorten the process of run-up; The pulley stops when moving to the vicinity of the high jump stand, the athlete presses the pole to bend, then takes off and completes the action of crossing the cross bar in the air, and finally falls on the upper surface of the cushion under the action of gravity.
    The present invention has the following advantages: An initial speed before take-off can be provided for an athlete by the cooperation of the pulley and the slide rail, and the athlete's action of inserting the pole in hands into the pole vault box can be omitted by rotating fit of the vaulting box structure and the pole.
    By omitting multiple actions in the pole vault, the athlete's physical strength can be greatly saved, so that the athlete concentrates on inverted crossing, and multiple times of training in a short time will not cause too much burden on the athlete's body; the athlete's training frequency of the pole vault is improved, and the athlete's performance of the pole vault is improved.
    At the same time, the speed of movement of the pulley along the base can be adjusted, and the athlete can obtain an initial speed exceeding his/her own speed limit before take-off, so that the athlete can experience the feeling of pole vault at different initial speeds, the athlete's experience of the pole vault is improved, and the training result is improved.
