Abstract
The utility model discloses a multi-purpose combined drawing ruler which comprises a transverse straight ruler and a vertical straight ruler and is characterized in that a slide track is arranged on the vertical straight ruler, a sliding chute is formed at the end part of the transverse straight ruler, the slide track on the vertical straight ruler is clamped into the sliding chute at the end part of the transverse straight ruler, the transverse straight ruler is perpendicular to the vertical straight ruler, a dovetail groove is formed on the transverse center line of the ruler surface of the transverse straight ruler, five dovetail sliders are embedded into the dovetail groove, a pen holder parallel to the vertical straight ruler is fixed on the dovetail sliders, a rotary pen sheath is arranged at the end part of the pen holder, and a piece of chalk is arranged inside the rotary pen sheath. Compared with the method of describing staves, four-line lattices, matts, concentric circles and the like by using a straight ruler or a pair of compasses in the present teaching, the utility model has the advantages of accuracy in line drawing and time and labor conservation, can improve teachers' teaching efficiency and learning efficiency, and meanwhile has a simple structure, and is convenient to carry and operate.
Description
Technical field
The utility model relates to a kind of teaching aid, the particularly a kind of combination picture chis of using that can draw concentric circles, matts, square grid, pinyin lattice, staff lattice more.
Background technology
In present teaching, the multiple situation calibration line that need draw is arranged, as in teaching of Chinese pin yin, the four line lattice that need on blackboard, draw let the student in four line lattice, write phonetic alphabet; When last music lesson, be with the ruler staff lattice that on blackboard, draw; When last mathematics class, circle or concentric circles often draw again.When drawing these calibration lines, generally all be to draw respectively with ruler or compasses.The deficiency that adopts ruler or compasses to draw different calibration lines respectively is: the one, waste time and energy, waste many teaching times during setting-out, and reduced teaching efficient and Students'learning efficient; The 2nd, ruler and compasses all are apparatus independently, carry inconvenience.
Summary of the invention
Circle or concentric circles that staff lattice that four line lattice, handwriting practicing matts, square grid, the music lesson that the purpose of the utility model is to provide a kind of phonetic that can draw fast to use used and mathematics class are used are easy to carry again, easy to operate many with combination picture chis.
For reaching above purpose, the technical scheme that the utility model adopted is: these are many with combination picture chi, comprise horizontal ruler and vertical ruler; It is characterized in that: described vertical ruler is provided with slide rail, and the end of described horizontal ruler is provided with chute, and the slide rail on the vertical ruler snaps in the chute of horizontal ruler end; Laterally ruler is vertical with vertical ruler, and slides along vertical ruler, on laterally straight related scale cross central line, is provided with dovetail groove; Be embedded in 5 dovetail slide blocks at dovetail groove; Fixing on the dovetail slide block and the vertical parallel penholder of ruler, be provided with the rotation pen cap in the end of penholder, in rotating the pen cap, be provided with chalk.
The utility model is also implemented through following measure: the end at vertical ruler is provided with pilot pin, so that the center of circle, location; The said rotation pen cap is fixed through screw, and when the rotation pen cap turned to desired position, rotating screw was fixed; On the dovetail slide block, be provided with the bolt of location, when the dovetail slide block slided into desired position, rotating bolt was fixed; Rear side at the dovetail slide block is provided with the scale arrow, and scale arrow and pen with rotary are enclosed within on the straight line, so that reading.
The beneficial effect of the utility model is: with in teaching, compare at present with draw staff lattice, four line lattice, matts, concentrically ringed method of ruler or compasses, setting-out is fast and accurately, and is time saving and energy saving, can improve teacher's teaching efficient and Students'learning efficient; Simultaneously, simple in structure, be easy to carry, easy to operate.
Description of drawings
Fig. 1 is the utility model structure schematic top plan view.
Among the figure: 1, horizontal ruler; 2, vertical ruler; 3, slide rail; 4, dovetail groove; 5, dovetail slide block; 6, penholder; 7, screw; 8, rotate the pen cap; 9, chalk; 10, pilot pin; 11, bolt; 12, scale arrow.
The specific embodiment
Make the utility model with reference to accompanying drawing 1.Should be many with combination picture chi, comprise horizontal ruler 1 and vertical ruler 2, it is characterized in that: described vertical ruler 2 is provided with slide rail 3; The end of described horizontal ruler 1 is provided with chute, and the slide rail 3 on the vertical ruler 2 snaps in the chute of horizontal ruler 1 end, and laterally ruler 1 is vertical with vertical ruler 2; And along vertical ruler 2 slips; Laterally being provided with dovetail groove 4 on the ruler 1 chi face cross central line, be embedded in 5 dovetail slide blocks 5 at dovetail groove 4, the penholder 6 parallel on fixing on the dovetail slide block 5 with vertical ruler 2; Be provided with the rotation pen cap 8 in the end of penholder 6, in rotating the pen cap 8, be provided with chalk 9.When using the utility model; If draw the parallel horizontal line of 3-5 root, turn to perpendicular to the horizontal direction of ruler 1 plate face rotating the pen cap 8, and adjust the spacing of dovetail slide block 5 and fixing; Vertical ruler 2 is transferred to laterally; And with vertical ruler 2 by being pressed on the blackboard, promote horizontal ruler 1, parallel horizontal line fast can draw on blackboard; Draw vertical line if desired, as long as vertical ruler 2 is transferred to vertically; Frame can be drawn horizontal parallel lines earlier if desired, draws vertical parallel lines again, is grid after intersecting; If draw circle; Can be with vertical ruler 2 perpendicular to blackboard, the pen cap 8 transfers to and is parallel to vertical ruler 2, and fixing; The point that touches blackboard with vertical ruler 2 is the center of circle; Rotate horizontal ruler 1, the circle that can draw, diameter of a circle are the distance of touching chalk 9 corresponding dovetail slide block 5 to the vertical rulers 2 of blackboard; If the picture concentric circles can make the chalk 8 on the dovetail slide block 5 more than 2 touch blackboard simultaneously.
Improvement as the utility model: the end at vertical ruler 2 is provided with pilot pin 10, so that the center of circle, location; The said rotation pen cap 8 is fixing through screw 7, and when the rotation pen cap 8 turned to desired position, rotating screw 7 was fixing; On dovetail slide block 5, be provided with the bolt 11 of location, when dovetail slide block 5 slided into desired position, rotating bolt 11 was fixing; Rear side at dovetail slide block 5 is provided with scale arrow 12, scale arrow 12 with rotate the pen cap 8 point-blank so that reading.
