Abstract

The utility model provides a mechanical measurer for the record of long jump, which can fast and accurately measure the record of long jump. The measurer comprises a takeoff board (4), an adjustment track (2) and a plastic track (1), wherein, the plastic track (1) is composed of a plurality of plastic strips (12). A bottom board (14) which is provided with grooves are laid under the plastic track, and a spring (13) is arranged in a groove among the bottom board (14) and the plastic strips (12). The spring (13) can be connected with the bottom board (14) and the plastic strips (12) under the action of pressure, and the outer side of each of the plastic strips (12) is provided with an electronic switch (16). Output signals of each switch are connected with a display (5) which comprises a processing unit (51) and a display board (52).

Description

Mechanical type long jump result measuring instrument

The utility model relates to a kind of surveying instrument of mechanical long jump result.

Long-jump is a motion of tempering leg muscle, development spring, but the measurement of long jump result is generally all cumbersome.Particularly standing long jump is as the main project in China's standard for physical training, and the number of its measurement and number of times are all very big.The present measuring method of China is that tape measure is placed on ground or the Jiao Dao mostly, and the gauger is according to measured's drop point range estimation achievement.But owing to do not have tangible impression usually on level land or the Jiao Dao, so the error during range estimation is bigger; And if the employing jumping is once surveyed method once then had both been required great effort time-consuming.

The utility model aims to provide a kind of long jump result measuring instrument, and this instrument is measured the achievement that it is jumped at testee's both feet when landing, thus the simplified measurement process, and suitably improve measuring accuracy.

The utility model provides a kind of mechanical type long jump result measuring instrument for this reason, and it comprises the take-off board that has scratch line, is arranged on the plastic cement road on the reference range adjustable track.Described plastic cement road can move on the reference range adjustable track, the plastic cement road is made up of some plastic strips, be equipped with the base plate of trough of belt below the plastic cement road, be provided with spring in the groove between base plate and the plastic strip, this spring can connect base plate and plastic strip under the effect of pressure; The outside of described each plastic strip all has an electronic switch that can receive base plate and plastic strip Continuity signal; The output signal of each switch is connected with a display; Comprise a display board that goes out processing unit in order to calculated signals and show result of calculation in the described display from scratch line to the distance the closest approach of stopping over according to switch.

Now in conjunction with the accompanying drawings the utility model is elaborated, wherein:

Fig. 1 is the three-dimensional outside drawing of this measuring instrument;

Fig. 2 is the rough schematic view of the utility model measuring instrument inner structure;

Fig. 3 (A) is the local enlarged diagram along Figure 1A-A;

Fig. 3 (B) is the local enlarged diagram along Figure 1B-B.

As shown in Figure 1, mechanical type long jump result measuring instrument of the present utility model comprises the take-off board 4 that has scratch line 3, is arranged on the plastic cement road 1 on the reference range adjustable track 2.

Described plastic cement road 1 can move on reference range adjustable track 2 according to different measurement requirement, and plastic cement road 1 is made up of some plastic strips 12.As 100 plastic strips are set on about 1 meter long plastic cement road, be equipped with the base plate 14 of trough of belt below the plastic cement road, be provided with spring 13 in the groove between base plate 14 and the plastic strip 12, the effect that this spring 13 can pressure connects base plate 14 and plastic strip 12 down.

The outside of described each plastic strip 12 all has an electronic switch 16 that can receive base plate 14 and plastic strip 12 Continuity signals.The output signal of each switch is connected with a display 5.

Comprise a processing unit 51 in the described display 5, this processing unit is handled the signal of electronic switch 16, when landing according to long-jump person's both feet of measuring, it calculates the distance of long-jump from scratch line electric signal the most nearby, and the result that will calculate is transported on the display board 52, so that the gauger reads the distance of long-jump.

Adopt method of the present utility model can make the measurement of long-jump simple, accurately.

Claims

1, a kind of mechanical type long jump result measuring instrument, it comprises the take-off board (4) that has scratch line (3), is arranged on the plastic cement road (1) on the reference range adjustable track (2), it is characterized in that:

Described plastic cement road (1) can be gone up at reference range adjustable track (2) and move, plastic cement road (1) is made up of some plastic strips (12), be equipped with the base plate (14) of trough of belt below the plastic cement road, be provided with spring (13) in the groove between base plate (14) and the plastic strip (12), this spring (13) can connect base plate (14) and plastic strip (12) under the effect of pressure;

The outside of described each plastic strip (12) all has an electronic switch (16) that can receive base plate (14) and plastic strip (12) Continuity signal; The output signal of each switch is connected with a display (5);
