Long jump measuring device for sports

Abstract

The invention discloses a long jump measuring device for sports, and belongs to a measuring device. The long jump measuring device comprises a take-off board, a landing board and a distance measuringreceiver, wherein the take-off board is provided with a weighing platform; the right side wall of the take-off board is connected with a weighing display panel; the bottom of the take-off board is connected with a distance display panel; the front side of a connecting plate is provided with an infrared sensor; the rear side of the connecting plate is fixedly connected with a bottom plate; the bottom plate is connected with an alarm transmitter and an alarm receiver; the bottom of the landing board is fixedly connected with a limiting sliding rail; the bottom of the limiting sliding rail is slidably connected with a sliding block; the surface of the front side of the sliding block is fixedly connected with a sensing head; and the distance measuring receiver is arranged above the landing board. Compared with the prior art, the long jump measuring device has the beneficial effects that the long jump measuring device is simple in structure and convenient to use, errors caused by changes ofthe thickness and the area of sandy soil can be avoided during long jump measurement, the distance can be directly converted into a score by controlling a control panel, and a display directly displays the score.

Description

technical field [0001] The invention relates to a measuring device, in particular to a long jump measuring device for sports. Background technique [0002] The data of the standing long jump reflects the physical coordination and explosive power of human movement, and also reflects the important items of students' physical fitness to a certain extent. Especially in the student stage, the standing long jump is a must-test item for physical training and examinations. In ordinary long jump training or competitions, bunkers are used for measurement. Not only the error is high, but also artificial The cost is high. After the personnel complete the long jump, changes in the thickness and area of ​​sand and soil will easily bring errors to the subsequent long jump personnel. [0003] In physical education teaching, the long jump and the distance test for the long jump are divided into two steps. It takes two people to measure manually with a tape measure, and then calculate and c...

AI Technical Summary

Problems solved by technology

The results measured by this method have large errors, the measurement is cumbersome and time-consuming, and the measured long jump results cannot be announced immediately

Both inaccurate and time-consuming, affecting the quality of physical education teaching
