Problems solved by technology
[0005] In order to solve the above-mentioned technical problems, the present invention provides a high jump training device for physical education, so as to solve the problem that the training personnel cannot identify the existing springboard itself when there are tiny cracks invisible to the naked eye, and there is a potential safety hazard of breaking during application. Moreover, when the existing springboard breaks accidentally, the trainer will lean forward excessively, which poses a safety hazard

The invention provides a high jump trainer for physical education, relates to the technical field of high jump training, and solves the problem that when an existing springboard has tiny cracks invisible to naked eyes, trainees cannot identify the tiny cracks, and the potential safety hazard that the cracks are broken during application exists. The high jump trainer for physical education comprises a jump plate, two supporting plates are arranged at the bottom of the jump plate and distributed in a bilateral symmetry mode, and the top faces of the rear ends of the two supporting plates are fixedly connected with the bottom face of the rear end of the jump plate through fasteners. Before daily use of the jump plate, detection can be carried out through water, and when the jump plate has tiny cracks invisible to naked eyes, the water permeates through the tiny cracks invisible to naked eyes and makes contact with the pigment layer, so that the color of the water is obviously displayed on the surface of the jump plate, workers can find the color in time conveniently, and potential safety hazards such as breakage caused by tiny cracks invisible to naked eyes during subsequent application are avoided.
Description
technical field [0001] The invention belongs to the technical field of high jump training, and more specifically relates to a high jump training device for physical education. Background technique [0002] High jump technical movements are difficult for non-professional athletes to master. When people train for high jump, they use their feet to step on the horizontal plate section of the movable board. Under the action of the spring, people can jump much higher than in ordinary training, prolonging the time of staying in the air, so that they can better grasp the rotation, etc. high jump action. [0003] For example, application number: CN201810433544.5 The present invention relates to the technical field of sports equipment, in particular to a springboard with a cushioning energy-absorbing structure. The springboard with cushioning and energy-absorbing structure includes an upper plate and a lower plate connected together by screws at one end, and a spring is fixed betwee...
