Abstract
The utility model relates to a drawing board for chemical learning and drawing, composed of a rectangular transparent plate whose periphery is provided with graduations, the rectangular transparent is provided with 18 apparatus drawing grooves in shape of an acids burette, an alcohol lamp, a separating funnel, a beaker, a graduated cylinder, a test tube, an evaporating dish, a long neck funnel, a flat bottom flask, etc. for chemical tests. The utility model can be used for specifically, quickly and simply drawing up a relative chemical test instrument diagram, which can obtain accurate and live drawing and enhance speed of equipment drawing for students and teachers. The utility model has the advantages of simple structure and convenient operation. The utility model relates to an ideal tool for chemistry studying and chemistry teaching for students and teachers.
Description
Use chemistry figure template a kind of more, relate to the drawing board that is used to draw the chemical test instrument, belong to drawing instrument.
In chemistry learning and teaching process, often need to draw the installation drawing of chemical reaction, but it is time-consuming to draw, even has phenomenons such as ratio is improper, crooked; The teacher teaches chemistry, when needing to draw, owing to there is not chemical drawing teaching aid, often takes a long time drawing, and influence the formal instruction time, and what have does not draw in order to save time, and only lectures content, but actual effect is not good.
The purpose of this utility model provides a kind of 18 kinds of instrument illustrated trench that chemical test is commonly used and comes together on the transparent panel, can make things convenient for, accurately, the chemistry figure templates of using of drawing rapidly more.
The technical solution of the utility model is: a kind of chemistry figure templates of using more, by around drawing groove on graduated rectangle transparent panel and the plate form, its drawing flute has acid buret, alcolhol burner, separatory funnel, beaker, graduated cylinder, test tube, asbestos gauge, evaporating dish, long neck funnel, boiling flask, round-bottomed flask, spherical hopper, kipp gas generator, wide-mouth bottle, gas bottle, conical flask, funnel, iron stand figure.
The utility model has the advantages that: 1, use simply, save time,, can plot needed instrument figure as long as pen is moved along the diagram inner edge; 2, owing to drawing according to diagram, so ratio is proper, lines slyness, accurately attractive in appearance; 3, excite the interest of student's learning chemistry, improve the effect that the teacher teaches chemistry.
Accompanying drawing is an overall schematic of the present utility model.
1 transparent panel, 2 illustrated trench, 3 scales.
Below in conjunction with embodiment and accompanying drawing the utility model is further described.
With reference to accompanying drawing, use the chemistry figure template, a rectangle transparent panel (1), its surrounding indexing (3) more, drawing groove (2) is arranged on transparent panel (1), be respectively acid buret, alcolhol burner, separatory funnel, beaker, graduated cylinder, test tube, asbestos gauge, evaporating dish, long neck funnel, boiling flask, round-bottomed flask, spherical hopper, kipp gas generator, wide-mouth bottle, gas bottle, conical flask, the figure of funnel and iron stand.
During use, only need the diagram of the instrument on the plate is placed on the position that will draw, move along the diagram inner edge with pen, in draw needed accurately, perfect figure.
Claims (1)
- The chemistry figure templates of using more, by around have the rectangle transparent panel (1) of scale (3) and the drawing groove (2) on the plate to form, it is characterized in that the drawing groove is the figure of acid buret, alcolhol burner, separatory funnel, beaker, graduated cylinder, test tube, asbestos gauge, evaporating dish, long neck funnel, boiling flask, round-bottomed flask, spherical hopper, kipp gas generator, wide-mouth bottle, gas bottle, conical flask, funnel and iron stand on the transparent panel.
