Abstract
The utility model relates to an adjustable cross rule which belongs to drawing instruments. The utility model is formed by connecting a vertical rule (2) with two crossfoots (1) with length scales through a moving groove (3) by a screw bolt (4), wherein, an angle notch (5) used for measuring angles (or making angles) and an indication line (6) used for measuring angles are arranged on endpoints of the moving groove (3). The utility model has the functions of various drawing tools such as foldable rules, T-shaped rules, set squares, protractor, etc. The utility model has the advantages of simple structure, simple manufacture and convenient operation and portability.
Description
Cross adjustable rule of the present utility model belongs to drawing instrument.
Existing drawing tool, except that the mapping pen, normal simultaneously by means of ruler, T-square, set square, protractor etc.Ruler can only be made straight line, and T-square is fixing because of one, can only make straight line, parallel lines and vertical line, and set square can only be made specific oblique angle lines such as 90 °, 60 °, 45 °, 30 °, and protractor can only angulation, uses the ruler setting-out again.Like this, bring inconvenience to the illustrator.
The purpose of this utility model is to avoid the deficiency of the single purposes of above-mentioned many drawing instruments and provide a kind of and can make straight line, do any angle, and the drawing instrument that can measure.
The utility model achieves the goal by following approach:
The cross adjustable rule is made up of crossfoot, perpendicular chi etc., and an end central part of a crossfoot one end and perpendicular chi has shifting chute, and the bolt that is used for clamping crossfoot, perpendicular chi passes shifting chute.Be carved with index line at the two ends of shifting chute, and be that the angle indentation for angulation (or doing the angle) usefulness is carved with in the center of circle with the point of contact at shifting chute and angulation index line junction for angulation (or doing the angle) usefulness.Unclamp bolt, crossfoot, perpendicular chi can move up and down and do to rotate arbitrarily around bolt, when the bolt axle center with when overlapping, can make any angle for the angle indentation center of angulation (or doing the angle) usefulness.
The utility model will be described in further detail embodiment in conjunction with the accompanying drawings:
Fig. 1, be the utility model cross adjustable rule schematic diagram.
As shown in Figure 1, the cross adjustable rule is by crossfoot (1), perpendicular chi (2) two big parts are formed, end central part at two chi sheets respectively has shifting chute (3), passing shifting chute (3) with bolt (4) connects two chi sheets, be carved with angulation (or doing the angle) index line (6) in the one or both ends of shifting chute (3), and the junction with shifting chute (3) and angulation (or doing the angle) index line (6) is the center of circle in the middle part of perpendicular chi, is radius is carved with angulation (or doing the angle) usefulness on perpendicular chi (2) all angle index or two centrosymmetric semicircle angle indentations (5) to be less than or equal to 1/2nd chi sheets wide.Also can be carved with all angle index or two centrosymmetric semicircle angle indentations (5) at other three end points of shifting chute (3).Loose bolts (4), two chi sheets can move up and down, and can change arbitrarily angled around bolt (4), on the one side or the both sides of chi sheet length scale (7) are arranged.When shifting chute (3) when two chi sheet tail ends are a bit overlapping and parallel, add long ruler; When shifting chute (3) when two chi sheet tail ends are a bit overlapping and vertical, square; When the shifting chute (3) on the crossfoot (1) at the shifting chute (3) of the end points at chi sheet middle part and perpendicular chi (2) when chi sheet top end is overlapping and vertical, T-square; When two shifting chutes (3) when chi sheet middle part end points is overlapping, can measure and make any angle by the angle indentation (5) of angulation (or doing the angle) usefulness, it is also very convenient to make parallel oblique line.The chi sheet can be together not overlapping the times spent two, is convenient to collection.
For making two chi sheets be fixed into the right angle, the spy has the snib hole (3) that is equally spaced in the both sides of crossfoot (1) shifting chute (3) and a side of perpendicular chi (2) shifting chute (3), the hole of two chi sheets is aimed in twos, and the joint of perpendicular chi (2) and crossfoot (1) just in time is on the graduation mark (7) of a fundamental length unit (as centimetre).Behind cross adjustable rule location, with two snibs (9) jam-pack snib holes (8), and tight a bolt (4) then two chi sheets make vertical fixing.When needs attachable mechanical stage sheet, take out snib (9) and loose bolts (4) and get final product, when crossfoot (1) and perpendicular chi (2) out of plumb, the snib hole (8) of two chis has a hole overlapping on some angle, and also available snib (9) and bolt/(4) are fixing.
Adjustable cross-rule of the present utility model combines the strong point of the multinomial drawing instruments such as set square, T-square, protractor, can drawing beeline, oblique line, parallel lines, make random angle, and energy length and angle, realized that a chi is multiplex.
