Abstract
The angle measuring ruler consists of an angle ruler and a graduated scale, the angle ruler semicircular disc is provided with angle scales, and the angle ruler semicircular disc is connected with a straight ruler and is connected with the graduated scale through a fixed shaft, so that the straight ruler and the graduated scale can rotate around the fixed shaft. When measuring the angle, the angle value and the side length of the measured angle can be directly read, so that the angle measurement, the line measurement and the drawing are very convenient and fast, and the device is suitable for being widely used as stationery.
Description
Technical field
The utility model relates to stationery, particularly multifunctional drawing stationery.
Background technology
Known protractor generally has a semi-disc, and semi arch is provided with angle index, and straight flange is provided with the length scale; Or have angle index on the set square.Generally can measure angle and the measured angle length of side length during angular surveying simultaneously, but this protractor often can not be measured the long length of measured angle longer sides when the angle measurement degree is big or measured angle length of side when longer simultaneously; When mapping, also need ruler or set square to be used.Bother.
Summary of the invention
The purpose of this utility model provides an a kind of chi multipotency, and is simple, convenient, cheap, is suitable for the popular angle square that uses.
The technical scheme that the utility model adopted is: angle square is made of bevel protractor and rule, and the bevel protractor semi-disc is provided with angle index, is connected with ruler on its semi-disc, bevel protractor is provided with fixed axis, band is read the rule of angular pin, is connected with bevel protractor by fixed axis, and can rotates around fixed axis.
Be carved with the length graduation mark on the ruler that the bevel protractor semi-disc is ined succession, this graduation mark begins from the axle center to chi end and vertical with 0 ° of graduation mark of angle index.
Rule is carved with inner side edge length graduation mark and outer side edges length graduation mark, and inner side edge length graduation mark begins to the chi end from the axle center.
The angular pin of reading of rule is fixed on the axis diameter place, and vertical with inner side edge length graduation mark.
Rule and bevel protractor ruler are also fashionable, and inner side edge length graduation mark is parallel with bevel protractor length graduation mark.
When angle measurement is spent, the axle center is placed the measured angle summit, the ruler of bevel protractor and rule place the measured angle both sides respectively, and reading angular pin is exactly the measured angle angle value at the scale of bevel protractor semi-disc indication, and measured angle radius value or polygonal side length can directly be read from rule inner side edge graduation mark.
Angle square of the present utility model is made of bevel protractor and rule, because the semi-disc bevel protractor is connected with ruler, and connects rule with fixed axis, makes rule to rotate around fixed axis.When angle measurement is spent, can directly read angle value and measured angle length of side length, make angle measurement, survey line, mapping very convenient, quick, be suitable for doing stationery and be extensive use of.

The specific embodiment
Introduce the utility model embodiment below in conjunction with accompanying drawing.
Among the figure:
1 bevel protractor, 2 fixed axis 3 are read angular pin 4 axle center 5 rules 6 and are surveyed minute hand 7 inner side edge length graduation marks 8 outer side edges length graduation marks 9 back of the body grooves 10 angle indexs 11 length graduation marks 12 grooves
Referring to Fig. 1, Fig. 2, Fig. 3, bevel protractor (1) has a semi-disc, and semi-disc is provided with angle index (10), be connected with ruler on the semi-disc, be carved with length graduation mark (11) on the chi, length graduation mark (11) from the axle center (4) begin to the chi end, and vertical with 0 ° of graduation mark of angle index (10).Bevel protractor (1) is provided with fixed axis (2), and there is an axis hole rule (5) front portion, is connected with bevel protractor (1) by fixed axis (2), and can rotates around fixed axis.(9) be rule back side groove, (12) are the bevel protractor grooves, and two groove fit are convenient to the rule rotation.Rule is carved with inner side edge length graduation mark (7) and outer side edges length graduation mark (8), and two length graduation marks (7), (8) are parallel, inner side edge length graduation mark (7) from the axle center (4) begin to the chi end.Read angular pin (3) and be fixed on rule axis diameter place, vertical with inner side edge length graduation mark (7), and rotate with rule (5), when rule and bevel protractor ruler and fashionable, read angular pin (3) and just in time overlap with 0 ° of scale of bevel protractor angle index (10), inner side edge length graduation mark (7) is parallel with bevel protractor length graduation mark (11).Survey minute hand (6) and be separately fixed at rule (5) tail end and bevel protractor (1) ruler tail end.
Referring to Fig. 4, when angle measurement is spent, axle center (4) are placed the measured angle summit, the ruler of bevel protractor and rule (5) overlap with the measured angle both sides respectively, reading angular pin (3) is exactly the measured angle angle value at the scale of bevel protractor semi-disc indication, and central angle radius value (or polygonal side length) can directly be read from rule inner side edge length graduation mark (7), bevel protractor length graduation mark (11).
When bevel protractor (1) semi-disc is enough big, on it except that being provided with angle index (10), also can be arranged side by side the length graduation mark, use two to survey minute hand (6) but profile section length, at this moment reading angular pin is exactly tested line segment length value at the length scale of bevel protractor semi-disc indication.
Claims (5)
1. angle square, the bevel protractor semi-disc is provided with angle index, it is characterized in that being connected with ruler on bevel protractor (1) semi-disc, and bevel protractor (1) is provided with fixed axis (2), the rule (5) that band is read angular pin (3) is connected with bevel protractor (1) by fixed axis (2), and can rotate around fixed axis (2).
