Description

A new teaching aid for English four-line and three-frame drawing

technical field

The utility model relates to the technical field of an English writing and marking device, in particular to a novel English four-line and three-grid line-drawing teaching aid.

Background technique

In the process of teaching English, writing on the blackboard is inseparable, especially the explanation of English words and letters, phonetic symbols, etc. During the explanation process, four lines and three grids are often needed to assist the explanation, so that the explanation can be clearly explained; explain about English words, Correct spelling of letters and phonetic symbols.

In the routine teaching of English and Chinese in primary schools, four lines and three frames are often used to guide students to learn the standard writing of words and uppercase and lowercase letters, as well as the correct writing of English sentences. Teachers often need to use a ruler to draw four lines and three grids on the blackboard, but it will waste time or draw the lines obliquely; sometimes teachers will prepare the white paper with four lines and three grids drawn in advance, and the disadvantage is that it is a waste of time And materials cannot be replenished in time after they are used up.

However, at present, most teachers use chalk to draw four lines and three grids directly. However, due to the length of the blackboard and personal blackboard writing habits, there are often cases where the four lines and three grids are drawn skewed, which affects the quality of teaching. . The patent number is CN203543459 utility model patent, its name is English writing cross-cutting device, which solves the problem that the teacher directly draws four lines and three grids by hand in the process of English teaching, but its complex structure and high manufacturing cost are not conducive to poverty-stricken areas teaching. The patent number is CN202541125 utility model patent, its name is a four-line three-grid liner, its structure is simple, it solves the problem that the teacher directly draws four-line three-grid by hand in the process of English teaching, but its long version It cannot be relatively fixed on the blackboard, that is, the long board will slide relative to the blackboard during the line drawing process, which affects the line drawing effect and reduces the teaching quality.

Therefore, we have developed a novel English four-line three-grid line drawing teaching aid which is simple in structure, low in manufacturing cost, easy to use, and improves teaching efficiency and classroom quality.

Utility model content

The purpose of the utility model is to provide a new type of English four-line three-grid line drawing teaching aid with simple structure, low manufacturing cost, convenient sliding board movement, smooth drawn lines, convenient use, and improved teaching efficiency and classroom quality.

In order to achieve said purpose, the utility model specifically adopts the following technical solutions:

A new type of English four-line three-grid line drawing teaching aid, which includes a teaching aid body frame 1, a slide plate 2, a suction cup 3, a horizontal bead device 4, and a chalk clamping device 5; it is characterized in that: the slide plate 2 is provided with a scale , and a chalk clamping device 5 is provided on it; the teaching aid body frame 1 is provided with guide rails 101 symmetrically on both sides up and down, and the back of the skateboard 2 is provided with pulleys 201 that are connected to the guide rails 101 symmetrically up and down, and A suction cup 3 is provided on the back of the teaching aid body frame 1, and a horizontal bead device 4 is provided at the center above the front.

The chalk clamping device 5 is composed of a cylinder body 501 , a spring 502 , a spring seat 503 and a chalk bayonet 504 .

The inside of the cylinder body 501 and the bottom of the rear cover are connected to one end of the spring 502, and the other end of the spring 502 is connected to the spring seat 503; a chalk bayonet 504 is provided below the spring 502, and inside the chalk bayonet 504 Installed with chalk.

The left and right upper corners of the teaching aid body frame 1 are rounded corners, and the left and right lower corners are square corners.

The utility model is a new type of English four-line three-grid line drawing teaching aid. The teaching aid is fixedly connected with the blackboard through the suction cup 3. Since the slide plate 2 is provided with a scale, the spacing of the chalk clamping device 5 is adjusted evenly through it, and then through Push the slide plate 2 to drive the chalk installed in the chalk clamping device 5 to draw lines, which is easy to operate, the slide plate 2 is easy to move and the lines drawn are smooth; the inside of the cylinder body 501 and the bottom of the rear cover are connected to one end of the spring 502, so The other end of described spring 502 is connected with spring seat 503; Described spring 502 below is provided with chalk bayonet 504, and chalk is installed in chalk bayonet 504; The distance to the blackboard can be adjusted by the spring 502; when the chalk is longer, the chalk tip is pressed against the blackboard, and the spring 502 is compressed to retract the chalk into the cylinder body 501. As the use progresses and the chalk is consumed, the spring 502 recovers and the top The chalk is drawn out so that it directly touches the blackboard to complete the line drawing; it is easy to operate and easy to use.

Compared with the prior art, the utility model has the beneficial effects that: the sliding plate 2 is provided with a scale, which facilitates the adjustment of the chalk clamping device 5, and can make the row spacing of the chalk clamping device 5 even, and the drawn The standard of four lines and three grids improves teaching efficiency and classroom quality; the teaching aid body frame 1 is provided with guide rails 101 symmetrically on both sides up and down, and the back of the skateboard 2 is provided with pulleys 201 cooperating with the guide rails 101 symmetrically. It is that the slide plate 2 is easy to move and the lines drawn are smooth; the inside of the cylinder body 501 and the bottom of the rear cover are connected to one end of the spring 502, and the other end of the spring 502 is connected to the spring seat 503; each adjacent chalk The distance between the chalk installed in the clamping device 5 relative to the blackboard can be adjusted by the spring 502; The consumption of chalk, the spring 502 recovers, pushes out the chalk, makes it directly contact with the blackboard, and completes the line drawing; easy to operate and easy to use; the center of the upper front of the teaching aid body frame 1 described above is provided with a horizontal bead device 4, which is used for line drawing. In the process, the problem that the drawn line is not parallel to the ground is avoided, and the teaching efficiency and classroom quality are improved.
