Abstract

A multifunctional universal rule of the utility model comprises a ruler plate, a positioning shaft and an assembly pulley. A boss is extended upwards from the ruler plate, and the displacement distance of the pulley wheel is controlled through the push and movement of the boss to draw various parallel lines, extended lines and forms. through the press of the positioning shaft of the central hole and the match with angulometers, figure holes and fixing holes, various circles, circular arcs and combination thereof can be drawn; through matching with the positioning shaft, the angulometer and the assembly pulley, various geometrical drawings can be drawn and the graphics can be enlarged, diminished and imitated. The utility model has the advantages of multiple use, simple structure, easy carrying, high precision and convenient use, and can replace flat rulers, parallel rulers, tee squares and set-squares.

Description

Multifunctional universal rule

The utility model relates to a kind of drawing instrument.

Public drawing rule only possesses a few functions, thereby when drawing engineering drawing, needs to use multiple instrument, and for the user, especially mobile big design and drawing personnel are very inconvenient.

The purpose of this utility model is to propose a kind of multi-functional multi-purpose rule, it possesses multiple functions such as parallel rule, T-square, ruler, half-round compasses, compasses, angle square, set square simultaneously, can draw various parallel lines, circle, circular arc, geometric figure, and possess a function such as the figure of making amplifies, dwindles.The figure of drawing is accurate, and error is little.

Utility model is achieved in that a kind of multi-functional multi-purpose rule, by chi plate 1, locating shaft 3 and assembly pulley 2 constitute, chi plate 1 extends upward a boss 18, establish index 181 on the boss, establish dividing plate 19 in the boss 18, the breach 191 of dividing plate 19 fixes the location axle sleeve 21 of assembly pulley 2 by projection 192, index 181 is corresponding one by one on the affixed pulley 23 in movable axostylus axostyle 22 both sides in the axle sleeve 21 of location, the scale 231 on the pulley 23 and boss 18; Be embedded locating shaft 3 in the 15 places activity of the back center hole of chi plate 1, locating shaft 3 is up and down in centre bore 15 by recessed edge 31; Establish scale 11,12 at the periphery of chi plate 1, the circular hole 17 of compensation line 14 and a plurality of different-diameters is established in its inboard, and angulometer 16 is established in the inboard of circular hole 17, and the angle line of this angulometer 16 is the central authorities by centre bore 15 all; Chi plate 1 periphery forms chamfer, and parallel lines fixing hole 13 is all established in its scale 11,12 inboards, and scale 11 is a graduated in English, and scale 12 is the metric system scale.

The utlity model has following characteristics:

1, can make the graphic plotting of simple and easy function and sophisticated functions according to individual demand.

2, use rapidly, accurately.

3, volume is little, does not take up space, and is easy to carry.

Fig. 1: the utility model three-dimensional exploded view.

Fig. 2: the utility model assembling schematic diagram.

Fig. 3: the utility model vertical view.

Now narrate example in conjunction with the accompanying drawings:

Referring to Fig. 1--Fig. 3: be combined to form multi-functional ten thousand by chi plate 1, assembly pulley 2, locating shaft 3

Fig. 2: the utility model assembling schematic diagram.

Fig. 3: the utility model vertical view.

Now narrate example in conjunction with the accompanying drawings:

Referring to Fig. 1--Fig. 3: be combined to form multi-functional multi-purpose rule by chi plate 1, assembly pulley 2, locating shaft 3, the periphery of chi plate 1 is chamfer, about be metric system scale 12, compensation line 14 is established in the inboard, front and back are graduated in English 11, two kinds of scale inboards etc. are arranged with a plurality of rhombus parallel lines fixing holes 13, at chi plate rear side middle part, the central authorities' (being metric system zero graduation place) that also are fixing hole 13 form a centre bore 15, establish angulometer 16 in semicircle position, the outside of centre bore 15, form the circular hole 17 of a plurality of different sizes in angulometer 16 both sides.Chi plate 1 extends upward a boss 18, and boss is provided with index 181, and the boss inboard is provided with dividing plate 19, form a breach 191 on the dividing plate 19, be provided with projection 192 in breach 191 both sides, but chi plate 1 mat projection 192 fixes the location axle sleeve 21 of assembly pulley 2, and axle sleeve 21 is positioned in the breach 191.

Assembly pulley 2 includes location axle sleeve 21, axostylus axostyle 22 and pulley 23, wherein assembly pulley 2 mats location axle sleeve 21 is sticked in the breach 191 of chi plate 1, the axostylus axostyle of assembly pulley 2 is positioned at axle sleeve 21,, and both sides respectively set firmly a pulley 23, pulley 23 slightly protrudes from outside the chi plate 1, so that boss 18 drives pulley rolling when passing, the pulley periphery is provided with scale 231, and scale 231 mat indexs 181 show the rolling distance of pulley.

Locating shaft 3 directly snaps in the centre bore 15 of chi plate 1, forms a recessed edge 31 in the central authorities of locating shaft 3, and a groove 32 is arranged on it, makes locating shaft 3 activity displacement in centre bore 15 by recessed edge 31, and available pen core inserts centre bore 15 location.

Pulley 23 is fixedly arranged on axostylus axostyle 22 both sides, during rolling and axostylus axostyle 22 be run-in synchronism, therefore, the mobile of pulley 23 is that parallel lines move, and can not produce skew.And the index 181 by boss 18 shows, knows the variation and the rolling number of turns of scale 231.

By the periphery scale of chi plate 1, the straight line that can directly draw, the passing of cooperation boss 18 is made the parallel lines of various spacings and is drawn.

By directly insert the fixing hole 13 of chi plate with pen core, by the passing up and down of boss, can make the straight line of random length or endless again, and can cooperate the drafting that is used as parallel lines and form that makes of compensation line 14.

By pushing of locating shaft 3, make chi plate 1 rotation and downwards by the arbitrary angle of scale line drawing of angulometer 16 or with the parallel lines of angle.

By the circular hole 17 of various different-diameters, can directly draw circle, or mat chi plate 1 is equidistant, various variation constitutional diagrams are made in equidistant displacement.

The interoperation of the displacement locating shaft 3 of chi plate 1 can be made the constitutional diagram that various round paper patterns change.

Chi plate 1, locating shaft 3, the interoperation of assembly pulley 2 can be made various figures, and similar fitgures amplify arbitrarily, dwindle and identical figure imitated.
