Abstract
The invention discloses an angle measuring triangular rule. One side of the triangular rule is provided with angle measuring graduations taking the middle point of the same side as a reference point; the angle measuring graduations are in a range of 0-180 degrees; the other sides of the triangular rule are carved with graduations for measuring straight lines; the graduations for measuring the straight lines are in a range of 0-100 mm; and the triangular rule is made of a plastic or stainless steel material, and is an equilateral triangular rule. Any angle in the range of 0-180 degrees can be measured through the angle measuring graduations on one of the three sides, and straight-line distances of 0-100 millimeters can be measured simultaneously by using the graduations for measuring the straight lines on the other two sides, so that the measuring functions of the triangular rule are verified.
Description
Technical field
The present invention relates to a kind of schooling apparatus, particularly a kind of angulation set square.
Background technology
Set square generally has drawing square and equilateral triangle chi now, drawing square can only be measured 30 °, 60 °, 45 ° and 90 °, and the equilateral triangle chi can only be measured 60 °, and set square can only be measured these special angles, can not measure other angle, so the angle that can measure very little.
Summary of the invention
The technical problem to be solved in the present invention is for the deficiencies in the prior art, proposes a kind of angulation set square that can measure multiple angles.
The technical problem to be solved in the present invention is to realize by the following technical programs.The present invention is a kind of angulation set square, be characterized in: one side at the angle measuring calibration take this side mid point as datum mark of being provided with of set square, the scope of described angle measuring calibration is 0～180 °, the described scale of measuring straight line that all is carved with on the other both sides of set square is measured the meter full scale of straight line between 0～100mm.
In a kind of angulation set square of the present invention technical scheme, further preferred technical scheme feature is: described set square is plastics or stainless steel material.
In a kind of angulation set square of the present invention technical scheme, further preferred technical scheme feature is: described set square is the equilateral triangle chi.
Compared with prior art, a kind of angulation set square of the present invention is by being arranged on the wherein angle measuring calibration on one side of three limits, can measure in 0～180 ° of scope arbitrarily angle, simultaneously, utilization is arranged on the scale of the measurement straight line on other both sides, can also measure the air line distance between 0～100mm, increase the measurement function of set square, make its function more diversified.
Description of drawings
Fig. 1 is structural representation of the present invention.
The specific embodiment
Referring to accompanying drawing, further describe concrete technical scheme of the present invention, so that those skilled in the art understands the present invention further, and do not consist of the restriction of its power.
Embodiment 1, with reference to Fig. 1, a kind of angulation set square, be provided with the angle measuring calibration 3 take this side mid point as datum mark on one side of set square 1, the scope of described angle measuring calibration 3 is 0～180 °, the described scale 2 of measuring straight line that all is carved with on set square 1 other both sides is measured scale 2 scopes of straight line between 0～100mm.
Embodiment 2, and in the embodiment 1 described angulation set square: described set square 1 is plastics or stainless steel material.
Embodiment, in embodiment 1 or the 2 described angulation set squares: described set square 1 is the equilateral triangle chi.Can also be drawing square, if drawing square can only be at hypotenuse angle measuring calibration to be set.
Claims (3)
1. angulation set square, it is characterized in that: one side at the angle measuring calibration take this side mid point as datum mark of being provided with of set square, the scope of described angle measuring calibration is 0～180 °, the described scale of measuring straight line that all is carved with on the other both sides of set square is measured the meter full scale of straight line between 0～100mm.
2. a kind of angulation set square according to claim 1, it is characterized in that: described set square is plastics or stainless steel material.
