Abstract

The utility model relates to a multi-purpose ruler. Through a parallel line (3), a vertical line (9) and an angle line (8) consulted for drawing and a positioning hole (5) convenient for drawing a circle, a drawer can conveniently and quickly draw the required parallel lines, vertical lines, angle lines and circles by using the ruler.

Description

Multipurpose ruler

Technical field

The utility model relates to a kind of Multipurpose ruler, is suitable for students in middle and primary schools' picture, engineering staff's drawing and teachers ' teaching and draws.

Background technology

At present, the function ratio of the ruler of selling on the market is more single, can only draw straight line, needs the parallel lines of line-spacing such as picture to be difficult to; Draw vertical line and also be subjected to the influence of wearing and tearing in the ruler turning, two crossing vertical lines can not well draw; Need picture angle line commonly used and bowlder often will finish by two set squares, protractor and compasses, can not be with ruler directly draw angle line commonly used and circle.

The utility model content

The utility model relates to a kind of Multipurpose ruler, uses once can easily draw ruler needed parallel lines, vertical line, angle line and circle in the time of can allowing the illustrator draw.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of Multipurpose ruler comprises parallel lines, vertical line, the angle line of drawing reference and makes things convenient for the round locating hole of picture.Wherein the parallel lines of 2 drawing references are in the inclined-plane in ruler front and the intersection on plane, and are parallel with 2 long limits of ruler; Vertical line is positioned at the centre of ruler, and is vertical with 2 parallel lines of ruler; Angle line has 5, evenly distributes between the long limit of ruler and vertical line, and divides 6 five equilibriums with this vertical angle etc.; Make things convenient for the locating hole of picture circle to have 6, uniform from the spacing of vertical line 1cm between both sides are with each locating hole.The blank position that prevents ruler right angle wearing and tearing is left and the position of flexible Application when drawing in these Multipurpose ruler both sides, and is provided with at these Multipurpose ruler two ends and is convenient to the picture roundlet and is convenient to circular hole with the mobile ruler of finger.

The beneficial effect of the utility model Multipurpose ruler is: can allow user draw very easily needed parallel lines, vertical line, angle line and circle when using ruler to draw, and not need other set square, protractor and compasses.Easier on the picture operation, more quick on the time at picture, on the drawing instrument cost, save more.What this ruler was designed also can temper the elaborative faculty of students in middle and primary schools when drawing with reference to parallel lines, vertical line, angle line and picture circle locating hole, with this person's that excites the picture innovative thinking.

The specific embodiment

For making the purpose of this utility model, technical scheme clearer, below in conjunction with accompanying drawing and specifically implement that the utility model is described in further detail.

Among each figure, the position of 1 flexible Application for the blank position that prevents ruler right angle wearing and tearing and when drawing, 2 is start index, 3 is parallel lines, 4 is the scale numeral, and 5 for making things convenient for the locating hole of picture circle, and 6 for stopping groove, 7 for ease of drawing roundlet and being convenient to the circular hole of pointing mobile ruler, 8 is angle line, and 9 is vertical line, and 10 is the ruler baseplane, 11 is the inclined-plane in ruler front, and 12 is the plane in ruler front.

Referring to Fig. 1～Fig. 2.When the user with after painting straight line, in the time of need drawing parallel lines again, parallel lines 3 alignment of this Multipurpose ruler can be pressed on that drawn just now straight line, rule along the long limit of ruler then, drawn this straight line is just with drawn just now that straight line parallel.

When the user needs the vertical line of a certain straight line of picture, the vertical line 9 of this Multipurpose ruler can be overlapped on the straight line that will draw, rule along the long limit of ruler then just can obtain one with the perpendicular vertical line of this straight line.

When the user need be that benchmark is when drawing commonly used angle line with a certain straight line, needed angle line 8 alignment of this ruler can be pressed on the datum line that will draw, along the long limit line of ruler, just can draw with this straight line is the angle line of the required picture of benchmark then.

When the user needs the picture bowlder,, directly draw if roundlet can be pressed in the position that will draw with 7 of the picture roundlet of being convenient to of this Multipurpose ruler.If there is not the bigger circle of size restrictions, can be inserted in this Multipurpose ruler respectively with two pens of drawing and make things convenient in the locating hole 5 of picture circle, be location, the center of circle with the pen of one of them locating hole, with the mobile picture circle of the pen rotation of another locating hole.Radius distance between two locating holes can be made by oneself as required, and the size of locating hole 5 is advisable to insert nib.

The position 1 of flexible Application can be to the bigger space that freely uses of user when the blank position that prevents the wearing and tearing of ruler right angle of this Multipurpose ruler and picture, and the while can also prevent the wearing and tearing of ruler right angle and have influence on the start index 2 of ruler and stop groove 6.The user can use when in picture, needing mobile ruler this ruler two ends design be convenient to conveniently move with the circular hole 7 of the mobile ruler of finger.The baseplane 10 of this Multipurpose ruler is designed to the plane, be provided with an inclined-plane 11 and plane 12 above, intersection between inclined-plane 11 and the plane 12 just in time is two parallel lines 3 of this Multipurpose ruler, its inclined-plane 11 is the stability of ruler when drawing for convenience and the accuracy of line, also is the design for aesthetic for ruler.This Multipurpose ruler is drawn locating hole 5 designs of circle between two numerals of ruler numeral 4, and both the accurate radius size of setting circle also can make full use of the neutral gear position between the ruler numeral 4.

This Multipurpose ruler deft design, succinct, reasonable, practical, especially be fit to students in middle and primary schools, this Multipurpose ruler is particularly convenient and swift in the student draws parallel lines, vertical line, angle line and the picture circle of using always, also can save time and cost to engineering drawing and drawing teaching.

The designed scale of this Multipurpose ruler accompanying drawing is fit to students in middle and primary schools' preferred size numerical value for this invention, the length size of this Multipurpose ruler can be according to the different designs of user's application places, its design of size in drawing teaching of drawing the locating hole 5 of circle is advisable to insert piece of chalk, is convenient to the picture roundlet and is convenient to the circular hole of pointing mobile ruler also to be advisable greater than finger.

The making material of this Multipurpose ruler is transparent plastic or other transparent nonmetallic materials.The succinct many designs with lines of this Multipurpose ruler will bring great convenience to students in middle and primary schools and vast drawing worker picture.
