Abstract
A multifunctional triangular ruler belongs to teaching aid for drawing angle easily, which comprises a first ruler, a second ruler and a third ruler hinged with each other, wherein the third ruler is provided with a central chute, one end of the second ruler via a pin and a fixing hand wheel is hinged in the central chute, the third ruler is provided with a first and a second ruler scales. The triangular ruler has large angle gage range, with direct and easy application, which is suitable for education.
Description
Technical field:
The utility model relates to a kind of stationery, particularly a kind of multi-functional triangular ruler.
Background technology:
The usual triangle ruler that uses carries inconvenience, and combination can angle very little, if it is just inconvenient more to re-use protractor.
The utility model content
The purpose of this utility model provides a kind of multi-functional triangular ruler, and it can mark a plurality of angles easily.
The technical scheme that the utility model technical solution problem is taked is:
Multi-functional triangular ruler, it is characterized in that comprise first chi, second chi and the 3rd chi that are hinged, described the 3rd chi is provided with the center chute, one end of second chi by bearing pin and fixedly handwheel be hinged in the chute of described center, on the 3rd chi, be provided with the first and second chi angle scales.
Described first and second chis are provided with the length scale.
The beneficial effects of the utility model are: this set square is bigger for the differences in angle weight range, uses more directly perceived, more convenient.
Description of drawings:
Figure is a structural representation of the present utility model.
Among the figure: 1 first chi, 2 second chis, 3 the 3rd chis, 21 fixing handwheels, first and second chi angle scale, 31 length scales.
The specific embodiment:
As figure, multi-functional triangular ruler comprises first chi 1, second chi 2 and the 3rd chi 3 that are hinged.Hinged between first chi 1 and second chi 2, between first chi 1 and the 3rd chi 3 by pin.The length of first chi 1, second chi 2 is fixed, and the maximum length of the 3rd chi 3 is a sum of the two.
The 3rd chi 3 is provided with longitudinal center's chute, an end of second chi by bearing pin and fixedly handwheel be hinged in the chute of described center, on the 3rd chi, be provided with the first and second chi angle scales.
Described angle scale is to form like this, can utilize trigonometric function to calculate bearing pin and fixing handwheel first and second chi corner dimensions during diverse location in the chute of center, and this angle is labeled on the 3rd chi 3 corresponding positions successively.
During use, the first and second chi angles only need adjust bearing pin and fixedly the position of handwheel in the chute of center get final product.
On first and second chis, even also can be provided with the length scale on the 3rd chi.
Claims (2)
1. multi-functional triangular ruler, it is characterized in that comprise first chi, second chi and the 3rd chi that are hinged, described the 3rd chi is provided with the center chute, one end of second chi by bearing pin and fixedly handwheel be hinged in the chute of described center, on the 3rd chi, be provided with the first and second chi angle scales.
2. multi-functional triangular ruler according to claim 1 is characterized in that, described first and second chis are provided with the length scale.
