Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0028] The invention is a sand-free landing device for teaching and training of long jump and triple jump. It is mainly composed of six parts: file surface nail foot fixing layer 1, water-air circulation buffer layer 2, frame grid sponge buffer layer 3, rubber surface fiber metal conductive mesh 4, color marking blanket falling surface 5, and trial jump interpretation display board 6. , the rubber surface fiber metal conduction net 4 is connected with the display board 6 of the trial jump interpretation by a lead. See details figure 1 , figure 2 .

[0029] File surface nail foot fixing layer 1 (eg image 3 , Figure 4 shown) is made of rubber plate 7 and steel strip 8. There are many nut holes designed and sorted on the steel band 8, and the nut holes are firmly connected with the nail feet 9 upper ends by screws. (Like the nails on the bottom o...

Abstract

The invention relates to a sand-free falling device for teaching and training of long jump and triple jump. The device has the advantages of simple and reasonable design structure, random pavement, convenience for exercise, cleanness and sanitation. The structure of the device is characterized in that a filed surface nail fixing layer, a water-vapor circular buffer layer, a framework grid sponge buffer layer, a rubber-faced fiber metal conducting net and a color-marked blanket falling surface layer are arranged in turn from the bottom to the top, wherein the rubber-faced fiber metal conducting net is connected with a trial jump identification display board through a lead.

Description

[0001] technical field [0002] The invention relates to a sand-free landing device used in the teaching and training of long jump and triple jump, which can be moved and installed at will, and belongs to the special equipment used in the teaching and training of long jump and triple jump. equipment. Background technique [0003] Long jump and triple jump are the men's, women's, youth, indoor, outdoor, and all-around competitions stipulated by the IAAF, the State General Administration of Sports, and the Ministry of Education. . However, at present, schools generally set up 1 to 2 bunkers at most. The number of bunkers is far from meeting the unified semester, season, content, progress, and planned curriculum design requirements of universities, middle schools and primary schools. Some schools have 3 to 6 classes in the long jump and third grade In the long jump course, facing 150-300 students, the teacher can only explain and demonstrate, and the teaching class has bec...
