Description

Universal rule

The utility model relates to a kind of drawing instrument.

The Bekaa isograph that China Patent No. CN882184199 is disclosed is though have the most of function of ruler, T-square, set square, protractor and compasses.But still exist following deficiency: institute's radius of a circle of painting can only be drawn bowlder and will use still sense inconvenient with two pencils centimetre to be unit; Register can not add up, and returns " 0 " in the time of can not using, and the user feels confused; Protractor can only Plane Angle, can't the quantity space angle; The holddown groove of drawing vertical line is a circular hole, and nib is moved.

The utility model purpose provides a kind of multi-purpose rule that integrates ruler, T-square, set square, protractor, compasses.

The utility model is so realized: whole rectangular, make with transparent lucite.The rectangle top is a metric scale 1, and the below of metric scale 1 is a foot rule 2, between metric scale 1 and the foot rule 2, has little diamond hole 3 every 5 millimeters, and the right is a metric scale 4, and the left side is a foot rule 5.The middle position of foot rule 2 belows is opened tongue 6, is equipped with the tourelle that band is returned " 0 " device digital watch in the tongue 6.The two ends of tongue 6 and below, have diameter to differ 2 millimeters 9 of circles, promptly be 2 millimeters, 4 millimeters, 6 millimeters, 8 millimeters, 10 millimeters, 12 millimeters, 14 millimeters, 16 millimeters, 18 millimeters.In the lower left of multi-purpose rule is protractor 8.There is fixed bar 9 at protractor 8 centers, fixed bar 9 fixing rotating angle squares 10.There is compasses central point 11 on right-hand at protractor 8 on the termination line of angle square 10 right-hand members.11 right-hand 7 millimeters places open compasses chute 12 from the compasses central point.But the pencil lead sliding sleeve 13 that move left and right is arranged in the chute 12.On the rectangular edges of chute 12 belows, there is metric system to carve chi 14.On the extended line of chute 12 center lines, establish another compasses central point 15 at protractor 8 lefts, can enlarge and draw 60 millimeters of radius of circles.

The utility model has the advantages that: it is little of 2 millimeters draw to draw diameter of a circle, and 320 millimeters of axis of great circles have adopted digital watch and returned " 0 " device, without data memory, and can return " 0 " at any time during use; The groove that has 3 to be convenient to by finger on the tourelle is arranged, be convenient to draw parallel lines and vertical line; Have to reach not effect partially, have diamond hole 3, in the nib patchhole 3, can not rock when drawing vertical line; Contain metric and English in a chi, easy to use; Protractor 8 has angle square 10, but the quantity space angle.
