It is convenient for students to carry. At the same time, it also increases the interest of traditional rulers and is easy to popularize.

Description

A learning math is divided into rulers

technical field

The utility model relates to a learning mathematics dividing ruler.

Background technique

Mathematics is a basic subject, and the knowledge of mathematics is interlinked. At this stage, there are no teaching aids for mathematics, and many parents are self-made teaching aids. In the process of mathematics teaching, students often need to use rulers. However, the current rulers generally can only draw straight lines. As a result, there is a disadvantage of a single function of the ruler. Therefore, in view of the existing problems in the prior art, there is an urgent need to provide a multifunctional ruler with a simple structure that can meet the requirements of learning mathematics, is easy to carry, and has the functions of an ordinary ruler.

SUMMARY OF THE INVENTION

In order to overcome the above-mentioned deficiencies of the prior art, the purpose of the present invention is to provide a solution to the problem of being able to learn mathematics at any time while being portable and lightweight, and having the characteristics of simple structure, convenience and practicality.

For achieving the above object, the technical scheme adopted in the present invention is:

A learning mathematics is divided into a ruler, comprising a rectangular ruler main body, a through hole is arranged on the right side of the ruler main body; a long through slot is arranged in the middle of the ruler main body; a long through slot is arranged in the middle of the ruler main body; Auxiliary ruler, the auxiliary ruler can slide in the long through groove; one end of the auxiliary ruler is provided with a square frame, the square frame is located above the scale of the long through groove, and the auxiliary ruler and the square frame are integrated and on the same horizontal plane.

The long through groove is provided with a scale, and the scale is set from right to left; the scale on the auxiliary ruler is set from left to right.

When the auxiliary ruler slides in the long through groove, the scales on the long through groove appear in the square frame in turn.

The square frame selects the target number, and the sub-ruler is the number into which the target number can be divided.

When the auxiliary ruler slides back and forth in the long through groove, the numbers into which the target numbers can be divided are correspondingly changed.

The ruler main body has a long through groove in the middle, and the square frame is placed in the long through groove and can slide back and forth.

The components are all made of PVC material.

The beneficial effects of the present utility model are:

Compared with the prior art, the present invention provides a kind of ruler which can meet the requirements of learning mathematics, is convenient to carry, and has the function of a common ruler. The square frame selects the target number, and the sub-ruler is the number into which the target number can be divided. When the auxiliary ruler slides back and forth in the long through groove, the numbers into which the target numbers can be divided are correspondingly changed. The auxiliary ruler with a square frame can move along the long guiding slot, and there is a through hole on the right side of the main ruler, so that the auxiliary ruler can complete the movement requirement without falling; learning mathematics can be divided into numbers according to the learning purpose, and the auxiliary ruler can be divided into numbers according to the learning purpose. The lower end is the number that the target number can be divided into; the reverse side of the main ruler is a normal ruler scale, which is small and easy to carry. It is convenient for students to carry, and it also increases the interest of traditional rulers and is easy to popularize.

Detailed ways

The structural principle and working principle of the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

Referring to Figures 1-5, a learning mathematics is divided into a ruler, including a rectangular ruler main body 2, the right side of the ruler main body 2 is provided with a through hole 5; the middle of the ruler main body 2 is provided with a long through slot 3; the middle of the ruler main body 2 is provided There is a long through groove 3; the long through groove 3 is provided with an auxiliary ruler 4, and the auxiliary ruler 4 can slide in the long through groove; one end of the auxiliary ruler is provided with a square frame, and the square frame is located above the scale of the long through groove, and the auxiliary ruler It is integral with the square frame and is on the same horizontal plane; the long through groove is provided with a scale, and the scale is set from right to left; the scale on the auxiliary ruler is set from left to right; the auxiliary ruler slides in the long through groove 3 , the scales on the long through grooves appear in the square frame in turn.

When the auxiliary ruler 4 slides back and forth in the long through slot 3, the numbers into which the target numbers can be divided will change accordingly.

The ruler main body 2 has a long through slot 3 in the middle, and the square frame 1 is placed in the long through slot 3 and can slide back and forth.

When in use, use the square frame 1 to frame the desired numbers, and the numbers on the sub-ruler 4 will also move correspondingly when the corresponding movement occurs.

The components are all made of PVC material.
