Description

Japanese seal

technical field

The utility model relates to teaching aids for primary school mathematics teaching, in particular to a Japanese-style stamp that can quickly print Japanese-style grids.

Background technique

At present, in the mathematics classroom, when teachers teach writing Arabic numerals 0 to 9, in order to standardize the writing of numbers, teachers often write numbers in the Japanese grid for demonstration, but the method of drawing the Japanese grid is time-consuming and laborious, even with some auxiliary Rulers, tools, etc. still need to be "drawn" with a pen. There are also Japanese grids with drawn grids on the market for pasting adsorption, but the adsorption force is limited, and it will slide when writing hard, and it is not easy to clean after wiping. In a word, the current way of drawing Japanese characters is time-consuming and laborious, and the effect is not good.

Contents of the invention

In order to solve the above problems, the utility model provides a stamp with Japanese characters. The method of "drawing" is no longer used to make the Japanese characters, but like a seal, the Japanese characters can be quickly formed on the blackboard, which is very convenient. fast.

The scheme that the utility model adopts is:

The Japanese grid seal is composed of a handle and a rectangular seal, and is characterized in that: there is a raised Japanese grid on the front of the seal, and the Japanese grid is made of sponge. The base of the stamp is made of 5 mm thick wooden board, and the Japanese grid is made of sponge. Because the sponge is absorbent, it is easy to absorb powder or liquid. Using the Japanese grid seal is easy to print on the blackboard Date format.

The beneficial effects of the utility model are:

The structure of the Japanese grid seal is simple, practical and low in cost. It is easy to print the Japanese grid on the blackboard by using the Japanese grid stamp.

Description of drawings

Below in conjunction with the figure of the present utility model further explanation:

Fig. 1 is a schematic diagram of the front view structure of the Japanese-style grid seal, and Fig. 2 is a side-view structural schematic diagram of the said Japanese-style grid seal. Among the figures, 1. Raised Japanese-style grid, 2. Seal, 3. Handle.

Detailed ways

As shown in Fig. 1 to Fig. 2, the Japanese-character grid seal is composed of a handle and a rectangular seal. Made of sponge. The base of the stamp is made of 5 mm thick wooden board, and the Japanese grid is made of sponge. Because the sponge is absorbent, it is easy to absorb powder or liquid. Using the Japanese grid seal is easy to print on the blackboard Date format. When using, hold the stamp with Japanese characters, dip the front of the stamp into powder or liquid, press the front of the stamp on the blackboard lightly, let the sponge on the front of the Japanese grid fit the blackboard, and the Japanese grid can be printed easily .

Claims (1)

1. One kind day the word lattice seal, constitute by handle and rectangle seal, it is characterized in that: there are the day word lattice of a convexity in the front of said seal, the word lattice were made by sponge in said day.
