Safe stand-trunk-bending detector

Abstract

A safe stand-trunk-bending detector comprises a 'T'-shaped platform combination and a four-detecting-scale combination, wherein the 'T'-shaped platform combination consists of a plurality of tubes or angle bars which are welded to one another to form a 'T'-shaped support; a platform plate and a step plate are respectively fixed on the top and a side surface of the support; two plug bushes are arranged on walls of two sides of a platform; castors are arranged on one side of the platform; detecting scales are respectively arranged at the fronts and the rears of four scale rods of the four-detecting-scale combination; each scale rod is provided with an upper sliding sleeve and a lower sliding sleeve; two ends of each connecting rod are fixed on the inner side surfaces of the corresponding upper sliding sleeve and the corresponding lower sliding sleeve; a push plate is fixed on the outer side of each lower sliding sleeve; a thigh stopping cross bar is fixed on the front sides of the two scale rods on the same side of the safe stand-trunk-bending detector; the lower ends of the scale rods are respectively inserted in the plug bushes and are fixed by screws; and when the tops of the push plates and the tops of the platform plate are positioned on the same plane, the upper edge of each upper sliding sleeve is aligned with zero points of two corresponding scale ends. The safe stand-trunk-bending detector is safe when testing, testing of four persons can be carried out simultaneously, the exercise testing efficiency is improved, and after the testing is finished, the tested persons can directly see test scores.

Description

technical field [0001] The invention belongs to the field of sports equipment, in particular to a safe standing body forward bending detector. Background technique [0002] It is one of the current national physical exercise standard test content to test the body's forward bending ability to reflect the degree of flexibility of a person. At present, the advantages and disadvantages of standing on the steps or sitting on the mat to test the body forward bending are: a. The process of going up and down the steps is easier than sitting down, with the soles of the feet on the benchmark 0 point, and the process of standing up after the test is simple and labor-saving, which can improve the test. Efficiency, but there is a hidden danger of falling forward when standing on the steps to test the body's forward bending, so at present, sitting on the mat is used to test the body's forward bending; The 0 point of the vertical scale is 30-40cm away from the ground, and the flat scale o...

At present, the advantages and disadvantages of standing on the steps or sitting on the mat to test the body forward bending are: a. The process of going up and down the steps is easier than sitting down, with the soles of the feet on the benchmark 0 point, and the process of standing up after the test is simple and labor-saving, which can improve the test. Efficiency, but there is a hidden danger of falling forward when standing on the steps to test the body's forward bending, so at present, sitting on the mat is used to test the body's forward bending; The 0 point of the vertical scale is 30-40cm away from the ground, and the flat scale of the tester used to test body forward bending while sitting on the mat is 35cm away from the ground, which makes the tester have to bow his head forward or squat down to see Clear the mm scales of the rulers of the two detectors. During the group test, the testers repeatedly do the above actions, which will easily cause waist and leg fatigue, and it is not convenient for the testees to see the test results in time.
