Automatic test instrument for running

Abstract

The invention relates to an automatic test instrument for running. The automatic test instrument includes a detachable tester and a test instrument main body which are connected through wireless signals; the detachable tester includes a support base, the support base is fixedly connected with a support frame, the support frame is in clearance fit with a shaft hole of a long connecting rod, and the long connecting rod is connected with a lengthening bar through a rotary knob; the lengthening bar is in clearance fit with a shaft hole of an L-shaped connecting rod, the bottom of the L-shaped connecting rod is in clearance fit with a support rod, the support rod is fixedly connected with the base, and the detachable tester can be quickly disassembled and assembled. The automatic test instrument for running solves the problems that the manual timing efficiency is low, the accuracy is not high and an existing test instrument is not convenient to carry, in a middle-distance race, many people can be tested at the same time, and after testing, quick disassembly can be achieved.

Description

technical field [0001] The invention relates to the field of physical fitness testing instruments, in particular to an automatic running tester. Background technique [0002] In the annual high school entrance examination in our country, physical examination is an indispensable part of the test. Among them, middle-distance running is a traditional important test item. The length of middle-distance running includes 200 meters, 400 meters, 800 meters, 1000 meters and 3000 meters. And 10,000 meters, the traditional middle and long-distance running timing is manually operated. During the centralized inspection of the high school entrance examination and other physical examinations, due to the large number of test students and the concentrated test time, the timekeeper needs to maintain concentration for a long time, resulting in the timing efficiency of manual timing. The shortcomings of low accuracy, insufficient accuracy, and high labor intensity for the timer in multi-person ...
