Abstract

The utility model discloses a high jump measuring instrument, comprising a scale and a moving-scale, wherein the surface of the scale is provided with scales increasing in turn from bottom to top till the upper end of the scale body; the moving-scale can slide along the scale, the surface of which is provided with scales, the starting scale of the moving-scale is the maximum of the scales of the scale, and the scales of the moving-scale increases in turn from top down till the lower end of the scale body; and the starting scale of the moving-scale is in coincidence with the maximum scale of the scale; when high jump height of an athlete is higher than the measurement height of the scale, the measurement can be performed only through drawing out the moving-scale, thus the high jump measuring instrument avoids measurement with the aids of chairs and other high objects during judges measure the height. The high jump measuring instrument has a simple structure and convenient use, and improves the work efficiency.

Description

The high jump measurement mechanism

Technical field

The utility model relates to a kind of sports and measures equipment, relates in particular to a kind of measurement mechanism of measuring the high jump height.

Background technology

At present, the referee generally adopts common wooden rule when measuring the height of sportsman's high jump, after the sportsman jumps to certain altitude, the referee has just bothered when measuring the height of sportsman's high jump very much, generally will measure by means of the contour thing of chair, the high and low, inconvenience very is if the measuring height of wooden rule is not enough, measurement also will superpose two wooden rules, measure trouble, misread number easily, influence athletic achievement, promptly delay the time, wasted manpower and materials again.

The utility model content

Technical problem to be solved in the utility model provides a kind of high jump measurement mechanism that is convenient for measuring the high jump height.

For solving the problems of the technologies described above, the technical solution of the utility model is: the high jump measurement mechanism, comprise that the surface is provided with the scale of scale, it is big that the scale of described scale becomes from bottom to up successively, until the upper end of scale body, also comprising can be along the moving chi that described scale slides, the surface is provided with scale, and the start index of described moving chi is the maximal value of scale scale, and it is big that the scale of described moving chi becomes from top to bottom successively, until the lower end of scale body; The start index of described moving chi overlaps with the maximum scale of described scale.

As a kind of improvement, be provided with the pull stop means between described scale and the described moving chi.

Improve as another kind, described pull stop means comprises limited block that is fixed on described moving chi bottom and the block that is fixed on described scale upper end.

Improve as another kind, the upper end of described moving chi is equipped with the moving chi reference seat that makes things convenient for the described moving chi of pull, and the measuring basis of described moving chi reference seat is positioned at the bottom surface of described moving chi reference seat.

Improve as another kind, the bottom of described scale is provided with the scale reference seat that conveniently described scale vertically is placed on the measured place, and the measuring basis of described scale reference seat is positioned at the bottom surface of described scale reference seat.

Owing to adopted technique scheme, the high jump measurement mechanism, comprise that the surface is provided with the scale of scale, it is big that the scale of described scale becomes from bottom to up successively, until the upper end of scale body, also comprising can be along the moving chi that described scale slides, the surface is provided with scale, and the start index of described moving chi is the maximal value of scale scale, and it is big that the scale of described moving chi becomes from top to bottom successively, until the lower end of scale body; The start index of described moving chi overlaps with the maximum scale of described scale; When height that the sportsman jumped is lower than the measuring height of scale, directly measure and get final product with scale, when the height of sportsman's high jump is higher than the scale measuring height, to move chi extracts out to measure and gets final product, avoided the referee when measuring, measure by means of the contour thing of chair, present embodiment is simple in structure, easy to use, improved work efficiency.

Embodiment

As shown in Figure 1, the high jump measurement mechanism, comprise that the surface is provided with the scale 1 of scale, it is big that the scale of described scale becomes from bottom to up successively, until the upper end of scale body, also comprising can be along the moving chi 2 that described scale 1 slides, the surface is provided with scale, and the start index of described moving chi 2 is the maximal value of scale scale, and it is big that the scale of described moving chi 2 becomes from top to bottom successively, until the lower end of scale body; The start index of described moving chi 2 overlaps with the maximum scale of described scale 1.

Be provided with the pull stop means between described scale 1 and the described moving chi 2.Described pull stop means comprises limited block 21 that is fixed on described moving chi 2 bottoms and the block 11 that is fixed on described scale 1 upper end.In case stop chi 2 is extracted out from scale 1, make troubles to use.

The upper end of described moving chi 2 is equipped with the moving chi reference seat 22 that makes things convenient for the described moving chi 2 of pull, and the measuring basis of described moving chi reference seat 22 is positioned at the bottom surface of described moving chi reference seat 22.

The bottom of described scale 1 is provided with the scale reference seat 12 that conveniently described scale 1 vertically is placed on the measured place, and the measuring basis of described scale reference seat 12 is positioned at the bottom surface of described scale reference seat 12.

The principle of work of present embodiment is as follows:

When height that the sportsman jumped is lower than the measuring height of scale 1, directly measures and get final product with scale 1.When the height of sportsman's jump exceeds the measuring height of scale 1, as shown in Figure 2, to move chi 2 extracts out, the height that the corresponding sportsman of bottom surface of chi reference seat 22 is jumped, the upper end of scale body is as the reading benchmark of moving chi 2, the data of reading on the driven chi 2 be exactly the height that the sportsman jumps.As shown in Figure 2, the height that the sportsman jumped is 163cm.
