Abstract
The utility model discloses an angle measuring instrument, which comprises a base. A vertical angular scale is mounted on the base and provided with scales, a support is mounted on the base, a metal sheet is hinged to the upper end of the support, the hinged point serves as a center of a circle of the angular scale, and the lower end of the metal sheet points to the zero position. The angle measuring instrument is high in measurement precision, simple in structure and low in cost.
Description
Technical field
The utility model relates to angel measuring instrument.
Background technology
In daily life, run into through regular meeting and take measurement of an angle.Up to the present, the simplest way that takes measurement of an angle is that the throughput hornwork is realized, but therefore the angle out of true of measuring, many special angel measuring instruments occurred now, but structure is complicated, the cost height.
Summary of the invention
The purpose of this utility model a kind of angel measuring instrument is provided, utilize angel measuring instrument of the present utility model, the precision height of Ce Lianging not only, and simple in structure, cost is low.
For achieving the above object, angel measuring instrument comprises base, and vertical angle scale is installed on the base, and angle scale is provided with scale; On the described base bracing frame is installed, the bracing frame upper end is hinged with sheet metal, and pin joint is the center of circle of angle scale, and 0 scale is pointed in the lower end of sheet metal.
When adopting angel measuring instrument of the present utility model to take measurement of an angle, one side of measuring the object angle degree is placed on the surface level, base is placed on the another side, at this moment, base tilts, and simultaneously, sheet metal rotates also vertically downward around pin joint under the self gravitation effect, the lower end of sheet metal is departed from 0 scale and is pointed to other scale, sheet metal scale extremely be the angle that will measure.
The beneficial effects of the utility model are: owing to obtain the angle that will measure, be subjected to the influence of extraneous factor little by the gravity of sheet metal self, therefore, and the precision height of measurement, and simple in structure, and cost is low.
Description of drawings
Fig. 1 is a structural drawing of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further elaborated.
Angel measuring instrument as shown in Figure 1 comprises base 1, bracing frame, sheet metal 4.Described bracing frame is a glass framework 2, the lower ending opening of glass framework 2, and be fixed on the base 1, fixed head 21 is installed on the medial surface of glass framework 2, is provided with vertical angle scale 3 in the glass framework, angle scale 3 is provided with scale, in the present embodiment, scale is from 0-90, and wherein an end of 0 scale is fixed on the upper surface of base 1, and an end of 90 scales is fixed on the fixed head 21.Glass framework 2 end faces are provided with hole 22, are provided with copper rod 6 in the hole 22, and the lower end of copper rod 6 extend in the glass framework 2, and glass framework 2 is stretched out in the upper end; Described sheet metal 4 is hinged on the lower end of copper rod 6, and when base was placed on the surface level, 0 scale was pointed in the lower end of sheet metal 4; Lower end at copper rod 6 also is hinged with tinsel 5, and the upper end of copper rod 6 is provided with sheet metal 7.
The angel measuring instrument of this structure both can take measurement of an angle, and can be used as electroscope again and used.When taking measurement of an angle, one side of measuring the object angle degree is placed on the surface level, base 1 is placed on the another side, at this moment, base 1 tilts, and simultaneously, sheet metal 4 rotates also vertically downward around pin joint under the self gravitation effect, the lower end of sheet metal is departed from 0 scale and is pointed to other scale, sheet metal scale extremely be the angle that will measure.When using, charged object is contacted with sheet metal 7, at this moment as electroscope, electric weight is delivered on sheet metal 4 and the tinsel 5 through copper rod 6, because sheet metal and tinsel are like charges, therefore, sheet metal and tinsel open, thereby realize the purpose of electrical verification.
Because the gravity by sheet metal self obtains the angle that will measure, is subjected to the influence of extraneous factor little, therefore, the precision height of measurement, and simple in structure, and cost is low.
