CN202130182U - Ruler rod for drawing parallel lines - Google Patents

Abstract

The utility model discloses a ruler rod for drawing parallel lines, which belongs to the field of tools, and is a conveniently-used, simple and high-efficiency special tool for occasions requiring frequent drawing of the parallel lines. The ruler rod comprises a ruler rod body in the shape of a regularly quadrangular prism, the section of the ruler rod body is square, and elongated rubber strips are longitudinally arranged in the middles of four ruler rod surfaces of the ruler rod body. The ruler rod is applicable to any studying and constructing operation occasions requiring frequent drawing of the parallel lines.

Description

Paint the parallel ruler bar

Technical field:

The utility model belongs to instrument apparatus field, specifically is meant line drawing chi bar.

Background technology:

Often need through the operation of line drawing in the plane of chi bar in daily life study and the operations construction; Wherein parallel lines or equal space line are drawn in the normal requirement of some concrete line drawing operation; And usual way often is to use the common online end positions place of the rectangular ruler of band shape that is prone to buy vertically to find equidistant points, connects horizontal equal space line or parallel lines again, and this maneuver is done also harmless when needing once in a while; But then need improve to improve work efficiency in the occasion that often needs; Improve accuracy, and the band shape ruler of extensively seeing is difficult to obviously satisfy the demand, transformation is worthy of consideration.

Summary of the invention:

The purpose of the utility model is the new technical scheme that a kind of chi bar is provided, and it can easily draw many equal space lines or parallel lines such as equal space line not efficiently.

The technical scheme of the utility model is achieved in that it comprises the chi body of rod, and the said chi body of rod is a four-prism, and the cross section is square, all vertically is processed with the rubber strip of strip on 4 chi pole faces of the chi body of rod between two parties.

The beneficial effect of the utility model be can for needs often paint equal space line or not the occasion of parallel lines such as equal space line one specific purpose tool efficiently simple and easy to use is provided.

Description of drawings:

Fig. 1 is a sectional elevation of painting the parallel ruler bar.

Fig. 2 is the external view of painting the parallel ruler bar.

Among each figure, 1 is the chi body of rod, and 2 is the chi pole face, and 3 is rubber strip.

The specific embodiment:

List can have multiple section selection from the chi body of rod 1 of angle the design's of line drawing line drawing chi; Such as triangle, quadrangle, pentagon etc.; But consider that practical operating effect just must be prudent definite; As select the cross section be the prism of triangle as the chi body of rod, because of its each angle be all the acute angle line drawing more convenient when the rolling chi body of rod but effort; As select the cross section be the prism of pentagon etc. as the chi body of rod, to be all the obtuse angle more laborsaving but not very convenient during at line drawing when the rolling chi body of rod because of its each angle; In view of this; Shown in Figure 2 like Fig. 1; The chi body of rod 1 should select four-prism to be (the occupied space heart all can) well; Be that its cross section is an also i.e. square of square, when the chi body of rod of this shape rolls also convenient during more laborsaving line drawing, the geometric properties of four-prism has determined the spacing that its every crest line all is parallel to each other and adjacent crest line to equate; Mean promptly that also the lines of painting along rib before and after this chi bar rolling that is placed on the plane all are parallel, the lines of painting along two adjacent edges all are equally spaced; On 4 chi pole faces 2 of this chi body of rod, all vertically paste or be inlaid with the soft rubber band 3 of the strip of tool certain width simultaneously between two parties; Thereby the adhesive force that it can let the chi bar touch line drawing basal plane, the increase chi body of rod and basal plane better prevents to skid; It can eliminate in the rolling chi bar operation even very small deviation is slided, and can improve the accuracy of line drawing greatly; The width of chi bar (being every edge lengths of the cross section of the chi body of rod) can select a less accurate processing and fabricating of size also clearly to mark the Digital ID of width; The groove sign of chi pole length and Digital ID also are shown on the crest line (all not to be drawn among the figure); The position of at first definite single line and length are drawn along crest line after putting good this chi bar during use; Width dimensions and institute's line drawing bar width at interval according to selected chi bar requires to roll in regular turn chi bar line drawing then; Or only roll one side just line drawing can draw narrower parallel lines or equal space line or three on rolling two sides or multiaspect again line drawing just can draw the equal space line of wide slightly broad or parallel lines such as equal space line not; All can be arbitrarily easy to operate freely; The neat standard of the parallel lines of drawing, more efficient quick is convenient and practical originally to paint the operation of parallel ruler bar with respect to usual maneuver, and is simple interesting new and original.

Claims (1)

1. paint the parallel ruler bar for one kind, it comprises the chi body of rod, it is characterized in that the chi body of rod is a four-prism, and the cross section is square, all vertically is processed with the rubber strip of strip on 4 chi pole faces of the chi body of rod between two parties.
