Abstract
A drawing board for teaching includes a measuring tape, a sliding block, a vertical ruler, a horizontal ruler, a frame and a whiteboard. The whiteboard is a white demonstration board for teaching, the surrounding of the whiteboard is connected with the frame, the upper side of the frame is provided with a slide track, the sliding block is arranged on the slide track, the sliding block can slide leftwards and rightwards along the slide track, the measuring tape is fixed on the sliding block, the extended end of the measuring tape is fixedly connected with the upper end of the vertical ruler and the lower end is connected with the horizontal ruler through a rotating shaft, the horizontal ruler can revolve the rotating shaft for 360 degrees and tighten the rotating shaft to make the vertical and horizontal rulers as T shape, the center of the horizontal ruler is provided with a row of round holes to form the drawing board for teaching. The T-shaped ruler of the utility model consisting of the vertical and the horizontal rulers can arbitrarily move in the vertical and horizontal direction, so that the utility model can replace ruler and compass to make drawings, which is time and labor saving and effectively improves the teaching quality.
Description
Technical field
The utility model relates to teaching aid, particularly relates to the teaching drawing board.
Background technology
When teacher draws geometric figure in teaching at present, use many drawing tools,, on blackboard or blank, draw a geometric figure, need frequently switch various apparatus as ruler, set square, compasses etc., quite time-consuming, bothersome, inconvenience.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of saving time and draws geometric teaching drawing board fast.
The technical scheme that adopts is:
Drawing board is used in teaching, comprises tape measure, slide block, perpendicular chi, crossfoot, framework, blank.Blank is the white demonstration board of teaching usefulness, be connected on the framework around its blank, described frame upper side is provided with slideway, and slide block places on the slideway, slide block can horizontally slip along slideway, tape measure is fixed on the slide block, the fixedly connected perpendicular chi of the external part of tape measure upper end, and vertical ruler lower end connects crossfoot by a rotating shaft, crossfoot can rotate 360 ° around the shaft, perpendicular chi of rotating shaft locking and crossfoot are " T " font, and the middle row's circular hole of establishing constitutes the teaching drawing board on crossfoot.
The utility model is formed "T"-shaped chi by crossfoot and perpendicular chi and can be moved arbitrarily in vertical, horizontal direction, can replace chi, rule mapping, saves time, and saves trouble the raising of favourable quality of instruction.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Drawing board is used in teaching, comprises tape measure 1, slide block 2, perpendicular chi 3, crossfoot 4, framework 8, blank 9.Blank 9 is the white demonstration board of teaching usefulness, be connected on the framework 8 around the blank 9, described framework 8 upsides are provided with slideway 5, slide block 2 places on the slideway 5, slide block 2 can horizontally slip along slideway, tape measure 1 can be wide 2cm, the steel tape of long 1cm, tape measure 1 are fixed on the slide block 2, the fixedly connected perpendicular chi of the external part of tape measure 13 upper ends, perpendicular chi 3 lower ends connect crossfoot 4 by a rotating shaft 7, crossfoot 4 can rotate 360 ° around the shaft, and rotating shaft can be manual control screw, nut tightens perpendicular chi 3 of nut check and crossfoot 4 and is " T " font, "T"-shaped chi can be put in the blank optional position, can be vertical, horizontal direction moves, can the section of drawing parallel lines, similar figures figures, crossfoot 4 segment distance of whenever being separated by is made a call to a circular hole 6, logical crossfoot rotates around the shaft, is convenient to blank stroke arc, the circle figures."T"-shaped chi also can be applicable on the blackboard, and perpendicular chi circle does not contract the time spent, places one jiao of blank or blackboard to get final product.
