The multifunctional magnetic sector comprises a ruler body and a chassis of a ruler head, wherein the chassis of the ruler head is arranged on a head part of the ruler body. The ruler body is movably installed on the chassis of the ruler head, can be rotated around the chassis of the ruler head within a range of 360 DEG and is provided with a brush and scales. The utility model has the advantages of complete functions, convenient carrying, high manufacture precision and wide purpose.
Description
Technical field
The utility model relates to a kind of panel beating worker setting-out that can be used as, and teachers ' teaching drawing teaching display-tool with sticking plastic can also doublely be done the magnetic, multi-functional ruler of teaching bar.
Background technology
The most basic instrument of drawing is ruler, compasses, protractor, three instruments indispensable, as panel beating worker setting-out, teach the teacher and also will use the religion bar, as teaching teacher's use is exactly traditional compasses least easily, now most blackboard is by the glass-reinforced plastic material manufacturing, compasses centering commonly used is stable inadequately, three instruments carry inconvenience in addition, teacher often lazyness is saved trouble, free-hand drawing uses free-hand plotting error too big on how much classes, causes the student to understand difficulty, influence the thinking of solving a problem, often answer because the excessive misleading of constructional error makes mistake.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art and provides a kind of with three drawing instrument unifications, make it easy to carry, and can draw satisfactory figure, make it in process with the aid of pictures, to develop the thinking of solving a problem, thereby can solve the magnetic, multi-functional ruler of exercise question smoothly.
The purpose of this utility model is achieved in that the chi head chassis that comprises blade, is arranged on the blade head, and blade is movably arranged on the chi head chassis, and blade can rotate in 360 degree scopes around chi head chassis, is provided with paintbrush and scale at blade.Described chi head chassis is provided with the protractor dial.Described chi head chassis is provided with magnet.Described chi head chassis is provided with center of circle locating hole.Described blade is provided with the vernier pen clipping device.Described vernier pen clipping device is provided with pen clip clamping screw and pen clip locking nut.Also be provided with paintbrush to a proper star on the described vernier pen clipping device, peep-hole and vernier lock-screw.Described blade is provided with ruler scale and radius of circle scale.Also be provided with the vernier baffle plate on the described blade, the vernier baffle plate is fixed on the blade by vernier baffle plate hold-down screw.Described peep-hole is arranged on the radius of circle scale.
The utlity model has multiple functionally, easy to carry, make the precision height, broad-spectrum advantage.Be used on the steel plate and draw, teaching, design, sheet metal setting-out blanking can be drawn straight line, any angle intersecting straight lines, parallel lines, circular arc, circle, can realize compasses, protractor, ruler multi-functional, if with the design of steel plate drawing board, also can save T-square.
Description of drawings
Fig. 1 is a front view of the present utility model.
Fig. 2 is a vertical view of the present utility model.
The specific embodiment
As shown in Figure 1, 2: the utility model comprises blade 6, is arranged on the chi head chassis 1 of blade head, blade 6 is movably arranged on the chi head chassis 1, and blade 6 can rotate in 360 degree scopes around chi head chassis 1, be provided with paintbrush 5 and scale at blade 6, described chi head chassis 1 is provided with protractor dial 3.Described chi head chassis 1 is provided with magnet 2.Described chi head chassis 1 is provided with center of circle locating hole 4.Described blade 6 is provided with vernier pen clipping device 14.Described vernier pen clipping device 14 is provided with pen clip clamping screw 15 and pen clip locking nut 16.Also be provided with paintbrush to a proper star 13 on the described vernier pen clipping device 14, peep-hole 12 and vernier lock-screw 11.Described blade 6 is provided with ruler scale 9 and radius of circle scale 10.Also be provided with vernier baffle plate 7 on the described blade 6, vernier baffle plate 7 is fixed on the blade 6 by vernier baffle plate hold-down screw 8.Described peep-hole 12 is arranged on the radius of circle scale 10.
Chi head chassis 1 is that steel are made, in on the chi head chassis 1 magnet 2 is housed, be with blade 6 outward, can turn round around the chassis between blade 6 and the chi head chassis 1, acrylic glass protractor dial 3 is by compressing between center circle column sleeve and the center chassis hole, radius of a circle is passed through on ruler scale limit, it is the extended line of radius of circle, its scale engraves numerical value by state's dimensioning, the radius of circle scale is to be the center of circle with the chi head center of circle on one side, with the center of circle each point value to the blade scale is radius, and the point that drawn circular arc meets at blade radius of circle scale datum line begins one section little arc to the blade side.
Embodiment one:
Draw straightway: the pen clip clamping screw 15 on the vernier pen clipping device 14 is loosened (not pulling down), get final product along blade 6 moving cursor pen clipping devices 14.Line segment length l equals the corresponding ruler scale value of ruler location benchmark terminal point, deducts the ruler scale value of ruler location benchmark starting point correspondence.
Embodiment two:
Draw any angle intersecting straight lines: press embodiment one and draw straightway, the angle that blade is rotated to requirement is drawn another straightway.
Embodiment three:
Draw angle at any angle: draw any angle by the method for embodiment two and intersect line segment, the prolongation of two line segments is got final product.
Embodiment four:
Draw circular arc or circle: look for arbitrarily in the plane a bit as the center of circle, if locate draw point with the center of circle when required precision is high, pass center of circle locating hole 4 on the chi head, location, center of circle draw point needle point is overlapped with the center of circle, put down the chi head again, the paintbrush on the vernier pen clipping device 14 is overlapped with blade radius of circle scale 10 proper star 13.For preventing vernier, lock-screw is tightened slightly (do not influence manual vernier move be advisable) along blade along blade 6 automatic slippages.The rotation blade can be drawn circular arc and circle to certain angle.Manual moving cursor can be drawn out isocentric circular arc or concentric circles,
Embodiment five:
Draw Line Segment: to draw the horizontal parallel line segment is example, the chi head is put in the lower left, paints a straight horizontal line segment, blade 6 is rotated counterclockwise 90 °, draw a vertical line, and point is write down scale value on this vertical line, and the chi head moves along vertical line, and the center of circle is positioned at certain point, blade turns clockwise 90 °, draw horizontal line, the chi head center of circle moves to next anchor point along vertical line, draws another straight line again.
