Abstract

The utility model relates to a multi-function combined ruler, which is characterized in that two rulers can all be freely moved after assembling through the chutes arranged on the ruler surfaces of the main and the auxiliary rulers a t-square and an angle square can be changed, and any angle can be altered by rotating the auxiliary ruler. When the scribing is conducted, arbitrary dimension can be altered by moving the main ruler. An ellipse can be drawn by a small chute arranged on the main ruler. When the auxiliary ruler is singly used, the circle with the required dimension can be drawn. When the auxiliary ruler is singly used as a straight ruler, if the length is not enough, the length can be lengthened by combining with the main ruler. The utility model is mainly used for publicity departments, woodworkers, teachers and students.

Description

Multi-fucntion combined ruler

The utility model is the drawing instrument of a kind of measurement and drawing geometric figures, especially collects outside the function of ruler, set square, protractor, compasses, angle square, T-square, also can draw the ellipses of different sizes and the multi-functional combination ruler at any angle.

Present known drawing appliance ubiquity the single and limitation of function, chi commonly used can only be used for measuring length and draw straight line, for drawing different angle line, circle, ellipse, measure different angles and often need a lot of drawing appliances, especially to drawing the ellipse of any specification, also there is not specific purpose tool at present.

The purpose of this utility model provides a kind of multi-functional combination ruler, and it can not only draw the straight line of different size, the ellipse of different major and minor axis, and energy measurement and any angle of drafting.More convenient to drawing various patterns, form.

The purpose of this utility model is achieved in that this chi is made up of two independent major-minor chis of setting up, be carved with a T shape groove parallel respectively with length direction in the centre of major-minor chi, connector when other annex is combination, movable pen are the necessary parts that all will use when drawing different graphic.

Owing to adopt such scheme, can draw and measure various geometric graphs easily, only adopted two rulers to combine, simple in structure, easy to carry, the scope of application is wide.

Below in conjunction with drawings and Examples the utility model is further specified.

Figure one: audio-visual picture of the present utility model.

Figure two: the A-A cutaway view among Fig. 1.

Figure three: indispensable drawing pen of the present utility model.

Among the figure: graduation mark 4, little T shape groove 5, (10) .(11 that 1,0 °～90 ° needle drawing line 2, T shape groove are 3,90 °～180 °) .(12) .(13) and transverse sectional view 8, spill nut 9, T shape screw 10, T shape nut 11, square washer 12, aperture 13, T shape screw 14, metal penholder 15, nut 16, aperture 17, sleeve nut 18, the pen core of band tip of outside drawing 6, the transverse sectional view 7 of main scale, secondary chi.

In Fig. 1: required angle can be drawn or measure to the graduation mark at main scale two ends (1) (3) under the rotation of secondary chi (7).T shape groove (2) is mobile mutually after the combination of major-minor two chis, arrangement drawing pen, can fix therein or slip arbitrarily, and the little groove of T shape (4) is fixing or mobile (5), makes any change of ellipse two fixed points.Sliding part (5) is to be used for the fastening line that uses when oval of drawing.

In Fig. 2: the secondary chi of main scale (6) (7) connects through T shape nibbed screw (9) spill cap (8), the multi-functional combination ruler that composition can change arbitrarily.The tip of T shape screw (9) is used for the centering of picture bowlder.T shape screw (13) and binding nut (10) combination, clamping square washer (11), the aperture in the square washer (12) is used for threading.

In Fig. 3: penholder (14) with tighten cover copper (17) pen core (18) and form a movable pen, spill nut (8) plain nut (15) is used for the picture bowlder is fixed in the secondary chi T-slot (2) penholder, hole (16) are used for picture threading when oval.

Claims

1, a kind of multi-functional combination ruler, by main scale, secondary chi, drawing pen combines, it is characterized in that: reticule is carved with at the two ends of main scale respectively, and a side is carved with the scale of measurement, and there is a T shape groove at the center along the scale direction, opposite side has a little T shape groove, in adorn two active screws; There is a T shape groove at the center of secondary chi along the scale direction, and all there is the graduation mark of measurement both sides; The penholder of drawing pen is a metal, and its external diameter has screw thread, is with two nuts on the penholder, and there is an aperture lower end, and sleeve is tightened in the bottom, interior dress pen core.

2, multi-functional combination ruler according to claim 1 is characterized in that: major-minor two chis by tip T shape screw in its T-slot.

3, multi-functional combination ruler according to claim 1 is characterized in that: in the little T shape groove on the main scale, sliding part connects with line, is installed with drawing pen therebetween.
