Abstract
The utility model discloses a kind of multifunctional drawing square, it solve the problem that existing functions of ruler is single, it is characterized in that: on chi body (1), set up a small circle (4), and angle mark (6) and parallel with chi limit 0 ° ~ 180 ° diameter lines (5) are set at the edge of this circle (4), the circle centre position of diameter line (5) bores one can through the small sircle hole (7) of pencil-lead.Have rational in infrastructure, make the advantages such as easy, easy to use, integrate setting-out, gage length and angle, to divide angle etc. equally multi-functional, be particluarly suitable for classmates and learn and use in teacher's teaching.
Description
One, technical field
The utility model belongs to surveying mapping instrument, relates in particular to a kind of multifunctional drawing square with picture straight line, angulation peace subangle.
Two, background technology
At present, no matter what market was sold is ruler or set square, their ubiquity functions are comparatively single, usually can only draw straight line or measure length, so people in order to realize setting-out, angulation, to divide etc. function equally, need to use by other instrument or multiple tool combinations, such operation bothers very much.Especially teacher is in teaching, needs repeatedly to demonstrate on blackboard, and multiple tool combinations uses more inconvenient.
Three, summary of the invention
The purpose of this utility model is exactly to overcome the deficiencies in the prior art, provide one can not only setting-out, outside gage length, also can carry out angulation, divide the multifunctional drawing square at angle equally.
The technical solution of the utility model is: it is made up of parts such as chi body, hand hole and length marks, chi body is set up a small circle, and angle mark and parallel with chi limit 0 ° ~ 180 ° diameter lines are set at the edge of this circle, the circle centre position of diameter line bores one can through the small sircle hole of pencil-lead.Described chi body can be ruler, set square, T-square and other difform ruler.
Effect of the present utility model is: have rational in infrastructure, make the advantages such as simple, on blade, only set up a circular protractor, i.e. reachability set setting-out, gage length, tolerance angle and bisects angle etc. are multi-functional in one, are especially applicable to classmates and learn to impart knowledge to students with teacher use.
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Four, accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: 1 is chi body, 2 is hand hole, and 3 is length mark, and 4 is circle, and 5 is diameter line, and 6 is angle mark, and 7 is small sircle hole.
Five, detailed description of the invention
As shown in Figure 1, for drawing square, on the basis making common drawing square, the side plate face of chi body 1 is set up the small circle 4 that a diameter is 1.5 centimetres, and angle mark 6 and parallel with chi limit 0 ° ~ 180 ° diameter lines 5 of 0 ° ~ 360 ° are set at the periphery of circle, the circle centre position of circle 4 bores the small sircle hole 7 that can be passed pencil-lead simultaneously.When implementing the utility model, not only can draw straight line, measure length, but also angle mark 6 diagonal angle on circle 4 can be utilized to measure.When needs are divided equally drawn angle, small circle 4 can be put into the angle that will divide equally, make the both sides at circle 4 line and angle tangent, reusable lead pen is through the upper point of small sircle hole 7 in the center of circle, the summit of joint angle and the point on firm putting after taking away ruler, the ray drawn is angular bisector.Have rational in infrastructure, make the advantages such as easy, easy to use, be particluarly suitable for classmates learn and teacher teaching in use.
