Description

TECHNICAL FIELD

[0001] The utility model relates to a toy technical field, concretely is a kind of intelligence toy. BACKGROUND

[0002] Since mathematics is a subject composed of abstract concepts and symbolic concepts, teachers and students have certain difficulties, especially at the primary school level. Elementary school students cannot fully learn the addition and subtraction and multiplication and division calculation tables of the before-and-after rhythm in the mathematics course, and cannot perform operations related to them, which are the most basic theme of the mathematics course. This problem causes students to develop a negative attitude towards mathematics throughout their educational lives and even fail in the mathematics course. Therefore, students must learn the necessary knowledge and skills of before-and-after rhythm addition, subtraction, multiplication and division operations.

[0003] PCT patent application with publication number WO2021 / 194448A1 discloses a multiplication and division teaching toy pen holder, which is composed of a pen holder and a toy. The product looks like a vertical cylindrical pen holder, and the toy is attached to the pen holder and separated from the top surface of the pen holder. Multiplication and division equations are inverse operations and are written on the pen barrel. Students multiply the numbers 1-10 with the numbers 1-10 at any time and anywhere, and write the equations on the front of the pen barrel. They also write the inverse (division) equations on the back of it (for example, 5X 3=15 and 15 / 3=5, and vice versa. The specific working principle is: the ability to write multiplication and division equations on the pen barrel and follow them on the same horizontal line makes it easier for students to perceive and understand the concept of equations. The multiplicand in the multiplication equation and the quotient written in each row of the division equation are the same number and are represented by a circular hole. In parallel, the product in the multiplication equation and the dividend in the division equation are the same number and are indicated from the square hole. This makes it easier for students to perceive the relationship between the equations. This visual coding in the equations helps students quickly and accurately identify, perceive, understand and learn multiplication-division equations and the relationship between the components of these equations.

[0004] However, the product is relatively complex, and it is difficult for elementary school students to operate, and the learning difficulty is also increased, which is difficult to arouse the interest of elementary school students, and even further increases the fear of learning mathematics due to high difficulty. UTILITY MODEL CONTENT

[0005] The utility model aims to provide an intelligence toy.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical scheme:

[0007] A kind of wisdom toy, including annular shell and rotatable setting at the center of annular shell indicating disc, the front surface of the annular shell is uniformly provided with a plurality of first marks along the circumference, the back of the annular shell is uniformly provided with a plurality of second marks along the circumference, the first mark and second mark correspond one by one in height direction, the front surface of the indicating disc is provided with third mark and first indicating mark, the back of the indicating disc is provided with fourth mark and second indicating mark, the front surface and back of the indicating disc rotate synchronously, when first indicating mark points to a certain first mark, second indicating mark points to a certain second mark.

[0008] Further, the inner wall of the annular shell is provided with a wave groove along the circumference, the indicating disc is provided with a limit needle, one end of the limit needle abuts in the wave groove, and the other end abuts in the indicating disc through a spring.

[0010] Further, the limit needle is provided with a baffle on one side in the limit slot, and the width of the baffle is greater than the width of the first opening.

[0011] Further, the first opening is provided with a chamfer away from one side of the limit slot.

[0012] Further, the top of the limit slot is open, and the inner wall of the front disc body or back disc body is provided with a cover corresponding to the top opening of the limit slot.

[0013] Further, the annular shell includes front shell and back shell on the front and back, and the inner surfaces of the front shell and back shell are provided with corresponding foolproof marks.

[0014] Further, the front shell and back shell are connected by a plurality of groups of column holes and tight-fitting columns.

[0015] Further, the outer surfaces of the front shell and back shell are both provided with mounting slots at the center, and the front disc body and back disc body are arranged in the mounting slots on the front shell and back shell respectively.

[0016] Further, the front disc body and back disc body are connected by a plurality of groups of column holes and tight-fitting columns.

[0017] Compared with the prior art, the beneficial effects of the present application are:

[0018] By setting a first and a second identifier on the front and back of the annular housing, and setting a third, a first, a fourth, and a second identifier on the front and back of the indicator dial, referring to the cited documents in the background art, the operation logic between the first and third identifiers is set to be the opposite of the operation logic between the second and fourth identifiers. The second identifier displays the result of the operation between the first and third identifiers, and the first identifier displays the result of the operation between the second and fourth identifiers. For example, the first identifier has 10 numbers, sequentially set to 1-10 along the circumference; the third identifier is "X5" (multiplied by 5); the second identifier is sequentially set to 5, 10, 15, 20, 25, 30, 35, 40, 45, 50 along the circumference; and the fourth identifier is set to... The "÷5" function is set so that when the first indicator points to 1, the second indicator points to 5. At this time, the operation logic between the first and third indicators is the opposite of the operation logic between the second and fourth indicators. Rotating the indicator dial makes the first indicator point to 2-10 in sequence, and the second indicator rotates synchronously and points to 10, 15, 20, 25, 30, 35, 40, 45, and 50 in sequence. The second indicator displays the operation result of the first and third indicators, and the first indicator displays the operation result of the second and fourth indicators. This makes it very easy for elementary school students to learn multiplication and division. Since the operation results on the front or back of the ring shell are on the other side, the operation on the front side can be done first, and then the other side can be flipped to check the answer, which increases the interest in learning.
