Abstract

The invention discloses a device for standing long jump. The device comprises a first plastic pad, a second plastic pad is clamped at the upper end of the first plastic pad, and a pressure sensor is arranged between the first plastic pad and the second plastic pad; the two ends of the first plastic pad and the two ends of the second plastic pad are in contact connection with connecting strips, thefirst plastic pad is provided with protrusions, and the second plastic pad is provided with a circular groove; the circular groove tightly sleeves the pressure sensor, the connecting strips are provided with first buckles, the first buckles are provided with first clamping blocks, the connecting strips are provided with second buckles, and the second buckles are provided with a second clamping blocks. The pressure sensor is arranged between the two layers of plastic, the two layers of plastic can be fastened through the buckles, and the pressure sensor is fixed so that the product can be usedoutdoors in all weather, the performance of an athlete can be measured conveniently, and the influence of the weather on matches can be eliminated.

Description

technical field [0001] The invention relates to the field of sports equipment, in particular to a device for standing long jump. Background technique [0002] A standing long jump is a long jump that starts from a standing position without an approach run. The 2014 "National Student Physical Health Standards" stipulates that the standing long jump is a compulsory item in the annual physical examination of junior high schools, high schools, and universities. Infrared non-contact automatic measurement of standing long jump distance, reflecting the explosive power level of human lower limbs. [0003] But the standing long jump equipment that adopts at present adopts infrared ray, but can not be placed outdoors completely, especially rainy and snowy day, is easily affected by weather and carries out standing long jump. Therefore, it is necessary to improve the existing technology to eliminate the influence of weather on the standing long jump, so that the equipment can be used...
