Abstract
The utility model discloses a blackboard for mathematics teaching, which comprises a board frame and a board body. Two longitudinal sliding grooves are respectively arranged on the left side and the right side of the board frame. A longitudinal sliding block which can slide upwards and downwards along the longitudinal sliding groove is placed in each longitudinal sliding groove. The longitudinal sliding blocks are matched with the longitudinal sliding grooves. A transverse ruler is fixedly arranged between the two longitudinal sliding blocks. Two transverse sliding grooves are respectively arranged on the upper side and the lower side of the board frame. A transverse sliding block which can slide leftwards and rightwards along the transverse sliding groove is placed in each transverse sliding groove. The transverse sliding blocks are matched with the transverse sliding grooves. A longitudinal ruler is fixedly arranged between the two transverse sliding blocks. Length scales are arranged on the transverse ruler and the longitudinal ruler. The longitudinal sliding grooves and the transverse sliding grooves are dovetail grooves. The blackboard for mathematics teaching has the beneficial effects that: 1) the structure is simple; and 2) horizontal lines, vertical lines, rectangular coordinates and tables are convenient to draw.
Description
Technical field
The utility model relates to a kind of teaching aid, particularly a kind of mathematical education apparatus.
Background technology
At present, in the mathematical education practice process, the teacher need draw horizontal line, vertical curve, rectangular co-ordinate figures on blackboard; Be generally ruler and draw the used teaching aid of these figures, still, when drawing these figures with ruler; Owing to need locate to ruler, thereby drafting efficient is lower.
Summary of the invention
The problem that the utility model will solve is: provide a kind of mathematical education of being convenient to draw horizontal line, vertical curve, rectangular co-ordinate and form to use blackboard.
In order to solve the problems of the technologies described above; The mathematical education of the utility model is used blackboard; Comprise sheet frame and plate body, the left and right sides of said sheet frame is equipped with a vertical chute, all is placed with the longitudinal sliding block that an ability slides up and down along vertical chute in said each vertical chute; Said longitudinal sliding block is complementary with vertical chute, is fixed with a horizontal ruler between said two longitudinal sliding blocks; The both sides up and down of said sheet frame are equipped with a horizontal concrete chute; All be placed with the transverse slider that an ability horizontally slips along horizontal concrete chute in said each horizontal concrete chute; Said transverse slider and horizontal concrete chute are complementary; Be fixed with a vertical ruler between said two transverse sliders, be equipped with the length scale on said horizontal ruler and the vertical ruler.
In order to improve the compactness of cooperation, the mathematical education of the utility model is used blackboard, and said vertical chute and horizontal concrete chute are dovetail groove.
The beneficial effect that the utility model is obtained is: (1) is simple in structure; (2) sheet frame is provided with vertical chute and horizontal concrete chute; Vertically be provided with longitudinal sliding block in the chute; Be provided with transverse slider in the horizontal concrete chute, be provided with horizontal ruler between the longitudinal sliding block, be provided with vertical ruler between the transverse slider; Vertically be equipped with the length scale on ruler and the horizontal ruler, thereby be convenient to draw horizontal line, vertical curve, rectangular co-ordinate and form.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1, transverse slider, 2, sheet frame, 3, horizontal concrete chute, 4, horizontal ruler, 5, plate body, 6, the length scale,
7, vertical chute, 8, longitudinal sliding block, 9, vertical ruler.
The specific embodiment
As shown in Figure 1; The mathematical education of the utility model is used blackboard; Comprise sheet frame 2 and plate body 5, the left and right sides of said sheet frame 2 is equipped with a vertical chute 7, all is placed with the longitudinal sliding block 8 that an ability slides up and down along vertical chute 7 in said each vertical chute 7; Said longitudinal sliding block 8 is complementary with vertical chute 7, is fixed with a horizontal ruler 4 between said two longitudinal sliding blocks 8; The both sides up and down of said sheet frame 2 are equipped with a horizontal concrete chute 3; All be placed with the transverse slider 1 that an ability horizontally slips along horizontal concrete chute 3 in said each horizontal concrete chute 3; Said transverse slider 1 is complementary with horizontal concrete chute 3; Be fixed with a vertical ruler 9 between said two transverse sliders 1, be equipped with length scale 6 on said horizontal ruler 4 and the vertical ruler 9; Said vertical chute 7 is dovetail groove with horizontal concrete chute 3.
In the time of concrete the use, along vertical ruler 9 paddlings, can draw vertical curve with chalk; With chalk ruler 4 paddlings transversely, can draw horizontal line; Horizontal ruler 4 and vertical ruler 9 are intersected, be convenient to draw rectangular co-ordinate,, be convenient to draw form with reference to the length scale 6 on vertical ruler 9 and the horizontal ruler 4, thus very easy to use.
The mathematical education of the utility model is used blackboard, and vertically chute 7 is a dovetail groove, has improved the compactness that vertical chute 7 cooperates with longitudinal sliding block 8; Horizontal concrete chute 3 is a dovetail groove, has improved the compactness that horizontal concrete chute 3 cooperates with transverse slider 1.
The utility model is not limited to above-mentioned embodiment, and anyone should learn the structural change of under the enlightenment of the utility model, making, every with the utlity model has identical or close technical scheme, all fall within the protection domain of the utility model.
