The purpose of this utility model is: in order to solve the problem that teachers can use mathematical formulas at any time during the teaching process to students for reference, so as to prevent students from being unable to remember the formulas and keep up with the teacher's teaching ideas when the teacher is teaching, and to make the teacher's teaching ideas Clear and students can keep up with the teacher's train of thought, the technical solution is as follows: 

A new type of teaching blackboard with a mathematical formula prompt board, which includes a blackboard 1, a placement slot 2, a slider 3, a prompt board 4, a prompt board frame 5, a clasp 6, a prompt board chute 7, and a sliding column 8. In that: the left side surface of the blackboard 1 is provided with a placement groove 2, a prompt board frame 5 is inserted inside the placement slot 2, and a slider 3 is fixedly connected to the middle of the upper and lower top surfaces of the prompt board frame 5, and the prompt A clasp 6 is fixedly connected to the middle of the left surface of the board frame 5, and several prompt board chutes 7 are horizontally arranged on the upper and lower surfaces of the interior of the prompt board frame 5, and each of the prompt board chute 7 is inserted with a slide Columns 8, a prompting board 4 is fixedly connected between the sliding posts 8, the left and right edges of the upper top surface of the prompting board 4 and the left and right edges of the lower top are respectively fixedly connected with the sliding posts 8, and the inside of the placement groove 2 The upper and lower surfaces are each provided with a convex chute, the convex chute cooperates with the slider 3, and the depth of the internal groove of the placement 2 is consistent with the length of the prompt board frame 5, and the length of the prompt board 4 The length is one-third of the inner width of the prompt board frame 5, and the sliding column 8 is inserted on the upper and lower surfaces of the prompt board 4, and is fixedly connected by a spring.

The beneficial effect of the utility model is: in order to solve the problem that the teacher can display the mathematical formulas to the students for reference at any time during the teaching process, so as to prevent the students from being unable to remember the formulas and keep up with the teacher's teaching ideas when the teacher is teaching, it can make the teacher teach The thinking is clear and the students can keep up with the teacher's thinking. the

Description of drawings:

Fig. 1 is a schematic diagram of the overall structure of the utility model.

Detailed ways:

With reference to Fig. 1 described a kind of novel teaching blackboard with mathematical formula prompting board, it comprises blackboard 1, placement groove 2, slide block 3, prompting board 4, prompting board frame 5, buckle hand 6, prompting board chute 7, slide The column 8 is characterized in that: the left side surface of the blackboard 1 is provided with a placement groove 2, a prompt board frame 5 is inserted inside the placement slot 2, and a slider is fixedly connected to the middle of the upper and lower top surfaces of the prompt board frame 5 3. A clasp 6 is fixedly connected to the middle of the left surface of the prompt board frame 5, and several prompt board chutes 7 are arranged horizontally on the upper and lower surfaces of the interior of the prompt board frame 5, and each of the prompt board chute 7 up and down Sliding columns 8 are inserted inside, and a prompting plate 4 is fixedly connected between the sliding columns 8. The left and right edges of the upper top surface of the prompting plate 4 and the left and right edges of the lower top of the prompting plate 4 are respectively fixedly connected with the sliding columns 8. The upper and lower surfaces of the placement groove 2 are respectively provided with a convex chute, and the convex chute cooperates with the slider 3, and the inner depth of the placement groove 2 is consistent with the length of the prompt board frame 5. The length of the prompting board 4 is one-third of the inner width of the prompting board frame 5, and the sliding post 8 is inserted on the upper and lower surfaces of the prompting board 4, and is fixedly connected by a spring.

When in use, firstly buckle the clasp 6 to pull out the prompt board frame 5 from the placement slot 2, then slide the prompt board 4 for pushing oil mathematical formula in the internal chute 7 of the prompt board frame 5, and at the same time pull out the prompt board 4 Placed in the groove 2, sometimes when solving a problem, it is easy to use multiple formulas and when the formula is not on a prompt board 4, two prompt boards 4 can be placed side by side and the two prompt boards 4 can be displayed to students simultaneously. the

Of course, the above description is not a limitation of the present utility model, and the present utility model is not limited to the above-mentioned examples, and changes, modifications, additions or replacements made by those skilled in the art within the essential scope of the present utility model are also acceptable.
