Abstract
The invention discloses a ruler, which does not easily break a piece of drawing paper and is used for equally dividing a straight line. The ruler comprises a triangle ruler, wherein the triangle ruler is made of transparent plastic; the bottom edge of the triangle ruler is provided with a bottom ruler; one oblique edge of the triangle ruler is provided with an equal dividing ruler; the equal dividing ruler is provided with a chute parallel to the edge of the equal dividing ruler; a sliding block is positioned on the equal dividing ruler; a protrusion at the lower part of the sliding block is embedded into the chute and is in sliding fit with the chute; the sliding block is screwed with a sliding ruler through a bolt and a butterfly screw; and both the bottom ruler and the equal dividing ruler are provided with scales and scale values. The structures of the bottom ruler and the equal dividing ruler are adopted, and the sliding ruler slides along the chute under the coordination of the sliding block, so after the bottom ruler is aligned with the straight line to be equally divided, only the sliding block is arranged at the equal dividing value position on the equal dividing ruler, the edge of the sliding ruler is aligned with the tail end of the straight line to be equally divided, the equal dividing ruler is gradually pushed and equal dividing points can be drawn.
Description
Technical field
The present invention relates to a kind of drawing instrument.
Background technology
Often needs wait the branch straight line in manual drawing course, use two kinds of instruments of compasses and ruler to come the five equilibrium straight line usually.A kind of method is directly to measure the direct five equilibrium of identical length with ruler; Another kind is measured length value with compasses exactly on ruler, on line segment, draw the arc five equilibrium then.But still second method with the most use, though score values such as this method are more accurate, compasses can if drawing quality is bad, also can tear drawing pricking a lot of eyes on the drawing, influence the integrity degree of drawing.
Summary of the invention
The purpose of this invention is to provide a kind of ruler that is difficult for causing the damaged five equilibrium straight line of drawing.
Technical scheme of the present invention is: comprise set square, said set square is a transparent plastic, and the base of set square is an end chi; A hypotenuse of said set square is an Equant ruler; This Equant ruler is provided with the chute that is parallel to this Equant ruler limit, and slide block is positioned on the Equant ruler, and the convexity of slide block bottom is embedded in the chute and with chute and is slidingly matched; Slide block and slip chi are spirally connected through bolt and butterfly screw, are equipped with scale and scale value on chi of the said end and the Equant ruler.
The present invention adopts the structure of end chi and Equant ruler; And chute slides the slip chi in the cooperation lower edge of slide block; Therefore, after the straight line of five equilibrium is wanted in end chi alignment, only need with slide block establish whole to the Equant ruler etc. the score value place; Align with the straight line end of wanting five equilibrium in the limit of slip chi, the horizontal sliding Equant ruler can be drawn out Along ent one by one.

Fig. 2 is the STRUCTURE DECOMPOSITION sketch map of Fig. 1;
Fig. 3 is the structural representation of slide block.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is done further explain, but do not constitute any restriction of the present invention.Illustrated in figures 1 and 2, the present invention includes set square 1, said set square 1 is a transparent plastic, and the base of set square 1 is an end chi 2, and a hypotenuse of said set square 1 is an Equant ruler 3, and this Equant ruler 3 is provided with the chute that is parallel to this Equant ruler limit.Slide block 5 is positioned on the Equant ruler 3, and is shown in Figure 3, and the convexity of slide block 5 bottoms is embedded in the chute and with chute and is slidingly matched, and slide block 5 is spirally connected through screw rod 7 and butterfly screw 6 with slip chi 4, is equipped with scale and scale value on chi of the said end 2 and the Equant ruler 3.During use; The straight line of five equilibrium is wanted in end chi 2 alignment, then slide block 5 is slided and alignment Equant ruler 3 on scale value, this scale value is to want the isodisperse of five equilibrium straight line; Loosening butterfly screw 6 and rotational slide chi 4; Alignd with the straight line end of wanting five equilibrium in the limit of slip chi 4, tighten butterfly screw 6, horizontal sliding Equant ruler 3 can be drawn out Along ent one by one at last.Slip chi 4 is spirally connected end for semicircle, and the diameter of this semicircle equates that with slide block 5 width the center of circle of this semicircle equals radius to the distance on Equant ruler limit, can guarantee like this correspondence after 4 rotations of slip chi etc. score value remain unchanged.
