Abstract
The utility model provides a drawing board for mathematical education in a college. In the mathematical education in the college, a teacher usually needs to draw a plurality of diagrams, curves and the like. The drawing board for the mathematical education in the college comprises a framework bottom board (2) with an upper beam (1); a spring adjuster (3) connected with a blackboard is arranged on the back of the framework bottom board; a magnetic sheet (4) is connected with the surface of the spring adjuster; a connection ring (5) is mounted below the upper beam; a grid board (7) with a hole (6) is mounted on the framework bottom board through the connection ring; the grid board is connected with a coordinate (8); and a panel (9) is mounted on the framework bottom board through the connection ring. The drawing board for the mathematical education in the college, provided by the utility model, is used for explaining advanced mathematics.
Description
Technical field:
the utility model relates to a kind of College Mathematics Teaching drawing board.
Background technology:
Some figures, curve etc. often need be drawn in
on blackboard in College Mathematics Teaching.Owing to do not have coordinate, grid on the existing blackboard; Increased the difficulty that the teacher draws, and the bigger error of the figure of drawing existence, cause the shape of function curve inaccuracy, figure nonstandard; Can influence student's visual experience, further cause teaching efficiency relatively poor.
Summary of the invention:
The purpose of
the utility model provides a kind of simple in structure, College Mathematics Teaching drawing board of having removable coordinate.
Above-mentioned purpose realizes through following technical scheme:
a kind of College Mathematics Teaching drawing board; Its composition comprises: have the chassis base of entablature, described chassis base back has the spring-loaded governor that is connected with blackboard, and described spring-loaded governor surface connects magnetic sheet; Connecting ring is equipped with in described entablature below; The waffle slab that has the hole is contained on the described chassis base through connecting ring, and described waffle slab connects coordinate, and panel is contained on the described chassis base through connecting ring.
described College Mathematics Teaching drawing board; Described waffle slab has the hole at the grid intersection place; Described coordinate comprises one group of one section coordinate that has arrow; The described coordinate other end has the hole, and the end that described coordinate has the hole is connected on the described waffle slab through drawing pin.
described College Mathematics Teaching drawing board, described panel bottom has magnetic sheet, and described spring-loaded governor upper end has hook.
Beneficial effect:
1. the utility model can be dressed up two or the three-dimensional desired position that is installed on the waffle slab with set of coordinates according to the needs of teaching and explain.
can be with reference to grid and reference axis when 2. the utility model is painted; So that standard with figure, curve drafting; Can draw plane coordinate system, three-dimensional coordinate system etc. when waffle slab is made, select suitable waffle slab to hang on the crossbeam when waiting to impart knowledge to students as required.
3. the utility model is simple in structure, easy to use, effectively standard the quality of drawing, improved teaching effect.
Description of drawings:
accompanying drawing 1 is the structural representation of this product.
accompanying drawing 2 is vertical views of accompanying drawing 1.
The specific embodiment:
Embodiment 1:
