Abstract
A kind of study mathematics divides into the ruler, including main scale and sub-scale; the auxiliary ruler is positioned in the main ruler, the auxiliary ruler with the square frame can move along the guide long through groove, and the through hole is formed in the right side of the main ruler, so that the auxiliary ruler can meet the moving requirement and cannot fall off; the learning mathematics is divided into figures which can be selected according to the learning purpose frame, and the lower end of the auxiliary ruler is the figure which can be divided into the target figure; the back side of the main ruler is provided with normal ruler scales, the whole ruler is small and convenient to carry, and the interesting of the traditional ruler is increased while the ruler is convenient for students to carry, so that the ruler is easy to popularize.
Description
Technical Field
The utility model relates to a study mathematics falls into ruler.
Background
Mathematics is the basic subject, and the knowledge ring of mathematics is detained mutually, does not have the teaching aid to mathematics divide into at present stage, and a lot of parents all are self-made teaching aid. In the process of mathematical education, students often need to use the ruler, but the existing ruler can only draw a straight line, so that the ruler has the defect of single function. Therefore, in order to solve the problems in the prior art, it is urgently needed to provide a multifunctional ruler which can satisfy the requirements of mathematics learning, is convenient to carry, has the functions of a common ruler and has a simple structure.
Disclosure of Invention
In order to overcome the defects of the prior art, the invention aims to provide a portable and light device which solves the problems of satisfying the requirement of learning at any time when learning mathematics is divided, and has the characteristics of simple structure, convenience and practicability.
In order to achieve the purpose, the invention adopts the technical scheme that:
a ruler for learning mathematics comprises a rectangular ruler main body, wherein a through hole is formed in the right side of the ruler main body; a long through groove is formed in the middle of the ruler main body; a long through groove is formed in the middle of the ruler main body; an auxiliary ruler is arranged in the long through groove and can slide in the long through groove; one end of the auxiliary ruler is provided with a square frame, the square frame is positioned above the scales of the long through grooves, and the auxiliary ruler and the square frame are integrated and positioned on the same horizontal plane.
Scales are arranged on the long through groove from right to left; the scales on the auxiliary ruler are arranged from left to right.
When the auxiliary ruler slides in the long through groove, the scales on the long through groove appear on the square frame in sequence.
The square frame selects a target number, and the auxiliary ruler is a 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 change correspondingly.
The middle part of the ruler main body is provided with a long through groove, and the square frame is arranged in the long through groove and can slide back and forth.
The parts are all made of PVC materials.
The utility model has the advantages that:
compared with the prior art, the ruler provided by the invention can meet the requirement of mathematics learning, is convenient to carry, and has the function of a common ruler. The square frame selects a target number, and the auxiliary ruler is a 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 change correspondingly. The auxiliary ruler with the square frame can move along the guide long through groove, and the through hole is formed in the right side of the main ruler, so that the auxiliary ruler can meet the moving requirement and cannot fall off; the learning mathematics is divided into figures which can be selected according to the learning purpose frame, and the lower end of the auxiliary ruler is the figure which can be divided into the target figure; the back side of the main ruler is provided with normal ruler scales, the whole ruler is small and convenient to carry, and the interesting of the traditional ruler is increased while the ruler is convenient for students to carry, so that the ruler is easy to popularize.

Detailed Description
The structure and operation of the present invention will be described in detail with reference to the accompanying drawings and embodiments.
Referring to fig. 1-5, a ruler for learning mathematics, which comprises a rectangular ruler main body 2, wherein the right side of the ruler main body 2 is provided with a through hole 5; a long through groove 3 is arranged in the middle of the ruler main body 2; a long through groove 3 is arranged in the middle of the ruler main body 2; an auxiliary ruler 4 is arranged in the long through groove 3, and the auxiliary ruler 4 can slide in the long through groove; one end of the auxiliary ruler is provided with a square frame, the square frame is positioned above the scales of the long through grooves, and the auxiliary ruler and the square frame are integrated and positioned on the same horizontal plane; scales are arranged on the long through groove from right to left; the scales on the auxiliary ruler are arranged from left to right; when the auxiliary ruler slides in the long through groove 3, the scales on the long through groove appear on the square frame in sequence.
When the auxiliary ruler 4 slides back and forth in the long through groove 3, the numbers into which the target numbers can be divided change correspondingly.
The middle part of the ruler main body 2 is provided with a long through groove 3, and the square frame 1 is arranged in the long through groove 3 and can slide back and forth.
When in use, the square frame 1 is used for selecting target numbers, and when corresponding movement occurs, the numbers on the auxiliary ruler 4 also move correspondingly.
The parts are all made of PVC materials.
