Abstract

A leveling device for high-jump bars mainly comprises a column frame, wherein an arc glass-tube leveling device is vertically arranged in the center part of the column frame, and two arc hooks, which have the same shape and the same size and are integrated to the column frame through connecting beams. During the height adjustment process of a high-jump bar, a person needs to hang the leveling device on the middle part of the high-jump bar through the two hooks, then adjusts the high-jump bar to a required height, adjusts the heights of the two ends of the high-jump bar so as to make the bubble in the bubble tube be located in the middle of two scale lines, then removes the leveling device from the high-jump bar, and thus the jump-bar is ensured to be in a horizontal sate. Through a design of hanging a leveling device through hooks, the leveling device is more convenient, and the result is more precise. The leveling device is small and light, and thus is convenient to carry or accommodate.

Description

A kind of high jump cross bar leveling instrument

Technical field the utility model belongs to field of sports equipment, relates in particular to a kind of device for high jump cross bar lining.

Background technology is current, and in high jump training and contest, ascending, descending cross bar height is one and works frequently.According to the rules of contest, in the time that cross bar ascending, descending completes, cross bar should be in horizontality.But in common contest process, more whether cross bar relied on referee to estimate or measure definitely with ruler in horizontality, having lack of standardization, inaccurate or not convenient problem.

Summary of the invention is for above-mentioned technical matters, and the utility model provides the whether proving installation in horizontality of a kind of mensuration cross bar simple in structure, easy to use, and convenient realization makes high jump cross bar in horizontality.

In order to solve the problems of the technologies described above, the technical scheme that the utility model provides is: a kind of high jump cross bar leveling instrument, comprises framework, arc glass pipe level, hook.Described framework is right cylinder, made by stainless steel or other hard material, framework upper central position is longitudinally inlayed an arc glass pipe level is installed, in pipe, be full of liquid and leave a bubble, bubble forever rests on peak in pipe, is laterally carved with respectively a groove at the two-end part of the arc glass pipe level outside surface bubble under horizontality; Described hook is that the identical arc hook of two shapes, size being connected as one by tie-beam forms, and two free-ends of hook weld or be bonded in the same side equal-height position of framework.

Adopt this kind of scheme, can realize easily and make high jump cross bar in horizontality, its function-stable, accurate, reliable.

Beneficial effect

One, the mode that this device suspends leveling instrument in midair by hook makes lining result accurately, reliably;

Two, the combination that this device is realized leveling instrument and cross bar by hook with separate, using method is convenient and can Reusability;

Three, this device volume is little, lightweight, is easy to carry or deposits.

Accompanying drawing explanation

Fig. 1 is schematic perspective view of the present utility model;

Fig. 2 is schematic side view of the present utility model.

Embodiment

The related a kind of high jump cross bar leveling instrument of the utility model as shown in Figure 1 and Figure 2.This device mainly comprises framework 1, arc glass pipe level 2, hook 5.Described framework 1 is right cylinder, made by stainless steel or other hard material, framework upper central position is longitudinally inlayed an arc glass pipe level 2 is installed, in pipe, be full of liquid and leave a bubble 3, bubble 3 forever rests on peak in pipe, is laterally carved with respectively a groove 4 at the two-end part of the arc glass pipe level 2 outside surface bubbles 3 under horizontality; Described hook 5 is that the identical arc hook of two shapes, size being connected as one by tie-beam forms, and two free-ends of hook 5 weld or be bonded in the same side equal-height position of framework 1.

Using method: in the time of ascending, descending high jump cross bar, the hook of leveling instrument is hung on to high jump cross bar middle part, cross bar is adjusted to the height needing, by regulating the height at cross bar two ends, make bubble in bubbler tube between two scale marks, leveling instrument is taken on cross bar, can be guaranteed that cross bar is in horizontality.

Claims

1. a high jump cross bar leveling instrument, comprises framework (1), arc glass pipe level (2), hook (5); It is characterized in that: framework (1) is right cylinder, made by stainless steel or other hard material, framework upper central position is longitudinally inlayed an arc glass pipe level (2) is installed, in pipe, be full of liquid and leave a bubble (3), bubble (3) forever rests on peak in pipe, is laterally carved with respectively a groove (4) at the two-end part of arc glass pipe level (2) the outside surface bubble (3) under horizontality; Described hook (5) is that the identical arc hook of two shapes, size being connected as one by tie-beam forms, and two free-ends of hook (5) weld or be bonded in the same side equal-height position of framework (1).
