Abstract
The utility model discloses a Chinese teaching square grid ruler which comprises a fixed ruler (1), a moveable ruler (2) and a positioning sliding block (3). The fixed ruler (1) and the moveable ruler (2) are L-shaped; two ends of the fixed ruler (1) and two ends of the moveable ruler (2) are respectively connected through the positioning sliding block (3) which is provided with moveable ruler fixing bolts (4); the fixed ruler (1) is provided with four circular holes (5) with the same radius; and the fixed ruler (1) and the moveable ruler (2) are provided with scale lines. The Chinese teaching square grid ruler has the advantages of being capable of being utilized to rapidly draw matts or square grids on a blackboard and convenient to utilize, saving time and effort, improving the teaching efficiency and quality and reducing the labor intensity of teachers.
Description
Technical field
The utility model relates to a kind of language teaching grid chi.
Background technology
In present language teaching, in order to allow the student finish writing the grid word, need in matts, to write earlier, in grid, write again, progressively form the custom of writing of Chinese character.But, in teacher's teaching, teacher need on blackboard, draw earlier matts or grid, inside write again, for the student does demonstration, when drawing matts or grid, generally be the picture with ruler single line single line at present, the horizontal flat heavily fortified point that can not guarantee a matts or grid line segment is straight, influence the attractive in appearance of Chinese characters, simultaneously, more loaded down with trivial details when drawing matts or grid, waste time and energy, reduced efficiency of teaching and quality.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of language teaching grid chi is provided.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of language teaching grid chi comprises that scale 1, moving chi 2 and positioning sliding block 3 constitute, scale 1 and moving chi 2 L-shaped shapes, and the two ends of scale 1 and moving chi 2 are connected by positioning sliding block 3 respectively, and positioning sliding block 3 is provided with moving chi set bolt 4.
Scale 1 is provided with 4 circular holes 5 that radius is identical.
Scale 1 and moving chi 2 are provided with graduation mark.
Scale 1 and moving chi 2 can be dismantled and separate, and the ruler that also can be used as in the mathematical education uses, and the circular hole on the scale 1 can be assisted the picture circle.
The beneficial effects of the utility model are: can be fast at blackboard draw matts or grid, easy to use, time saving and energy saving, improved efficiency of teaching and quality, reduced teacher's labour intensity.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Among the figure, 1 scale, 2 moving chis, 3 positioning sliding blocks, 4 set bolts, 5 circular holes.
The specific embodiment
