Abstract
An angle indicator comprises a compass, a rotating shaft, an angle pointer made of a non-metallic material, and a dial scale, wherein the compass is fixed at the bottom end of the rotating shaft, the angle pointer is fixedly mounted at the top end of the rotating shaft, the dial scale is fixedly arranged below the angle pointer and concentric with the cross section of the rotating shaft, and graduation lines indicating angles and angle values are arranged around the center of the dial scale. The utility model has the advantages that the angle indicator utilizes the south pointing property of the compass to conveniently display the angles indicated by different instrument stands during an optical experiment, so that the angles between the instrument stands can further be conveniently calculated, thereby avoiding the problem of the inconvenient measurement of a protractor during the experiment, and achieving high precision; the structure is very simple; and the angle indicator can also be used in other experiments for measuring angles between instrument stands.
Description
Technical field
The utility model relates to a kind of experiment device, specifically is a kind of angle display instrument.
Background technology
In Experiments of Optics, angulation is difficult for measuring with protractor between each instrument stand, and experimental result is exerted an influence, and causes the experiment degree of accuracy to descend, and reduces experiment effect.
The utility model content
In order to overcome the shortcoming that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of angle display instrument, and it can record angulation between the instrument stand and precision degree height easily in Experiments of Optics.
The technical scheme that its technical matters that solves the utility model adopts is: this angle display instrument comprises compass, rotating shaft, the nonmetal angle indicator of making, index dial; Described compass is fixed on the bottom of rotating shaft, and the top of this rotating shaft installs angle indicator, and index dial is installed in the below of angle indicator and concentric with the rotating shaft cross section, is provided with the scale mark and the angle numerical value of expression angle around the index dial center.
During use, fix an angle display instrument on each instrument stand, and adjust each angle display instrument, when making the datum line aligning Due South of instrument stand, the zero graduation line of the angle indicator of its angle display instrument and index dial coincides.When instrument stand was arbitrarily placed, compass will drive angle of angle indicator indication by rotating shaft, and the difference of angle shown in the angle display instrument on per two instrument stands is the angle that become between two instrument stands.
As further technical scheme of the present utility model:
In this angle display instrument, described compass places in the airtight metal shell, and angle indicator is positioned at this metal shell top.Most of experiments interference that can both generate electromagnetic waves places these interference of maskable in the airtight metal shell with compass.
In this angle display instrument, angle indicator and index dial place in the upper shell, and upper shell comprises a water white protective cover, this protective cover be arranged on index dial directly over.
The beneficial effects of the utility model are: it utilizes compass to indicate southern character, in Experiments of Optics, can show the angle that each instrument stand is indicated easily, and then can calculate the mutual angulation of each instrument stand easily, thereby avoid the problem that the usefulness protractor is inconvenient to measure in experiment, and precision degree height; Its structure is also very simple in addition; Also can be used for surveying angulation between the instrument stand in other experiments.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described further:
Fig. 1 is a main cut-open view of the present utility model;
Fig. 2 is a vertical view of the present utility model;
Among the figure: 1 protective cover, 2 angle indicators, 3 index dials, 4 rotating shafts, 5 compasses, 6 metal shells.
Embodiment
As shown in Figure 1 and Figure 2, this angle display instrument mainly comprises compass 5, rotating shaft 4, the nonmetal angle indicator of making 2, index dial 3.
Compass 5 is fixed on the bottom of rotating shaft 4, and the top of this rotating shaft 4 installs angle indicator 2.Compass 5 places in the airtight metal shell 6, and angle indicator 2 is positioned at the top of this metal shell 6.Most of experiments interference that can both generate electromagnetic waves places these interference of maskable in the airtight metal shell with compass.
During use, fix an angle display instrument on each instrument stand, and adjust each angle display instrument, when making the datum line aligning Due South of instrument stand, the angle indicator 2 of its angle display instrument coincides with the zero graduation line of index dial 3.When instrument stand was arbitrarily placed, compass 5 will drive angle of angle indicators 2 indications by rotating shaft 4, and the difference of angle shown in the angle display instrument on per two instrument stands is the angle that become between two instrument stands.
Claims (3)
1. the angle display instrument is characterized in that: comprise compass, rotating shaft, the nonmetal angle indicator of making, index dial; Described compass is fixed on the bottom of rotating shaft, and the top of this rotating shaft installs angle indicator, and index dial is installed in the below of angle indicator and concentric with the rotating shaft cross section, is provided with the scale mark and the angle numerical value of expression angle around the index dial center.
2. angle display instrument according to claim 1 is characterized in that: described compass places in the airtight metal shell, and angle indicator is positioned at this metal shell top.
