[0004] Aiming at the shortcomings of the existing javelin's final force and the angle of release that are not easy to grasp, the present invention provides a control device for teaching the javelin's final force. The device is easy to operate, occupies a small area, and can reasonably control the height and angle of the javelin. Establish a good feeling of muscle exertion and form a standardized final exertion movement, which can effectively shorten the training cycle

Embodiment Construction
[0020] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0021] The control device for javelin final force teaching of the present invention includes A column 9 and B column 10 with different heights fixed at intervals, the height of A column is higher than the B column by a certain size, and a javelin is connected between the upper part of A column and the upper part of B column Guide cable 3, on the described javelin guide cable, slide and install exercise javelin 4 along the length direction; A column and B column are respectively provided with electric height-angle adjusting device, to regulate the height and the angle of javelin regulation guide cable.
[0022] The electric height-angle adjustment device is a screw nut pair or a rack and pinion pair installed in the A column and the B column, the nut or rack that can run up and down is installed with a slider, and the javelin guide cable 3 is connected to...

A control device for teaching of final thrust in javelin throwing is characterized in that a stand column A and a stand column B which are fixed at intervals and different in height are included, the stand column A is certain higher than the stand column B, a javelin guide steel cable is connected between the upper portion of the stand column A and the upper portion of the stand column B, and a training javelin is arranged on the javelin guide steel cable in a sliding mode in the length direction; the stand column A and the stand column B are respectively provided with an electric height-angle adjusting device which is used for adjusting the height and angle of the javelin guide steel cable. The control device for teaching of final thrust in javelin throwing has the technological advantages that students can master final thrust in the training process, javelins can be thrown out at proper angles, good muscle power exertion feeling can be established through repeated practice, furthermore stable dynamic stereotypy can be formed, and the technical problems that in the prior imitation, students only can practice by hands and can not conveniently master connecting of run-up and final thrust in javelin throwing are solved.
Description
technical field [0001] The invention relates to a control device for javelin final force teaching, which belongs to the technical field of sports equipment. Background technique [0002] The javelin throw is an all-around competition for male and female teenagers stipulated by the IAAF, the State General Administration of Sports, and the Ministry of Education. The complete technique of throwing the javelin includes four parts: holding the gun, holding the gun, running up, final force and buffering. Among them, the final force is the most important technical part of throwing the javelin, which determines the instant speed, angle and position of the javelin in the air. The state of flying, but the current school teaching and training process lacks special training equipment for javelins. Practitioners do not have a clear understanding or reference objects for using force along the longitudinal axis of javelins and shooting at an appropriate angle. The old imitation teaching ha...
