Abstract
The utility model relates to a multi-functional protractor, which comprises a large semi-circular protractor, a small semi-circular protractor and an indicator, wherein the large semi-circular protractor is coaxially connected to the small semi-circular protractor, a weight is disposed at a position of the axis center of the large semi-circular protractor and the small semi-circular protractor and connected to the indicator. The multi-functional protractor is capable of being used to measure an inclination angle of an single inclined plane, an inclination angle of a double inclined plane and an included angle of two incline planes, thereby the multi-functional protractor has multiple functions, further is simple in manufacturing and convenient in utilization.
Description
Affiliated technical field
The utility model relates to a kind of multi-function protractor.
Background technology
The generally only suitable measurement plane angle of common protractor for some three-dimensional inclination angle of inclined plane, angle, is measured very inconvenient.
Summary of the invention
The purpose of this utility model provides the multi-function protractor that can measure various angles.
The technical scheme that the utility model is taked is: a kind of multi-function protractor, comprise more than half round protractor, the round protractor of smaller part and pointer, it is characterized in that more than half round protractor and coaxial linking to each other of the round protractor of smaller part, and be provided with weight at axle center place, and pointer and weight link together.
Adopt the utility model, can measure monocline face inclination angle, double inclined plane inclination angle, two inclined-plane angles, have multiple function, and make simple, easy to use.
Description of drawings
Fig. 1 is a schematic top plan view of the present utility model.
Fig. 2 is a schematic cross-section of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
With reference to Fig. 1, Fig. 2, this multi-function protractor comprises more than half round protractor 1, the round protractor 2 of smaller part and pointer 3, and more than half round protractor 1 and the round protractor 2 of smaller part are by 4 coaxial linking to each other of axle, and the base is consistent, and being provided with weight 5 at axle center place, pointer 3 links together with weight 5.
During use, when needs are measured monocline face inclination angle, more than half round protractor 1 and the round protractor 2 of smaller part are merged, and be placed directly on the inclined-plane, the base of maintenance dose hornwork and measured inclined-plane match, under the effect of weight 5, pointer 3 can rotate, and treats that the mutual residual value of indication angle when pointer 3 is static is exactly this inclination angle of inclined plane.When needs are measured the double inclined plane inclination angle, more than half round protractor 1 and round protractor 2 counter-rotatings of smaller part are come, and be placed directly on the inclined-plane, keep the base of more than half round protractor 1 and the round protractor 2 of smaller part and two measured inclined-planes to match respectively, under the effect of weight 5, pointer 3 can rotate, when treating that pointer 3 is static, the complementary angle of the angle number on the more than half round protractor 1 of pointer 3 indications and the round protractor 2 of smaller part is inclination angle separately, two inclined-planes.When needs are measured two inclined-plane angles, more than half round protractor 1 and round protractor 2 counter-rotatings of smaller part are come, and be placed directly on the inclined-plane, keep the base of more than half round protractor 1 and the round protractor 2 of smaller part and two measured inclined-planes to match respectively, the angle of reading between the two nullity lines on the round protractor 2 of more than half round protractor 1 and smaller part is two inclined-plane angles.
