Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of mathematical teaching aids, and in particular to a magnetic laser direction indicator for mathematical teaching aids. Background Technology
[0002] In the mathematics teaching system, direction teaching is an important knowledge point that combines practicality and fundamentality. It not only builds a bridge connecting mathematics with real life for students, but also plays a key role in the cultivation of multi-dimensional abilities. From the perspective of life application, direction knowledge is closely related to scenarios such as daily travel and spatial planning. By recognizing basic directions such as east, south, west, and north, and learning practical methods such as using a compass and map to mark directions, students can quickly master the skill of identifying directions and easily cope with practical problems such as planning routes to school and finding their way when traveling. This transforms mathematical knowledge into the ability to solve life problems. From the perspective of ability development, direction teaching can effectively exercise students' spatial perception and logical thinking abilities. In the process of judging the relative positions of objects and describing the direction of a route, students need to build spatial models in their minds and sort out the directional relationships. This process not only deepens their understanding of spatial concepts, but also improves the accuracy of logical reasoning and language expression.
[0003] Traditional teaching methods often rely on planar direction diagrams or verbal explanations by teachers, making it difficult for students to intuitively and clearly understand the concept of direction and the angular relationships between different directions, resulting in poor teaching effectiveness. To address this, we propose a magnetic laser direction finder as a mathematical teaching aid. Utility Model Content
[0004] The purpose of this invention is to provide a magnetic laser direction indicator as a mathematical teaching tool to solve the problem that traditional teaching methods often rely on planar direction diagrams or verbal explanations by teachers, making it difficult for students to intuitively and clearly understand the concept of direction and the angular relationship between different directions, resulting in poor teaching effectiveness.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a magnetic laser direction indicator for mathematical teaching, comprising a rotating disk, multiple indicator seats, an outer scale, a laser emitting device, and a magnetic component. The indicator seats are evenly distributed around the rotating disk and are used to indicate the basic direction. The outer scale is disposed on the rotating disk. The laser emitting device is disposed at the center of the rotating disk and is used to emit laser light to indicate the direction. The magnetic component is disposed on the back of the rotating disk and is used to attract the direction indicator to a magnetic surface.
[0006] As a preferred embodiment, there are four indicator seats, each pointing in one of the four basic directions: east, south, west, and north.
[0007] As a preferred embodiment, the outer ring scale is a ring scale with four arrays from 0 to 90 degrees and is located on the edge of the rotating disk, and the rotating disk is provided with an inner ring scale with the readings opposite to those on the outer ring scale.
[0008] As a preferred embodiment, a hollow groove is provided at the center of the rotating disk, and a mounting bracket is fixedly installed in the hollow groove.
[0009] As a preferred embodiment, the laser emitting device includes a mounting housing and a laser emitter disposed within the mounting housing. A rotating column is fixedly mounted on the bottom of the mounting housing, and a rotating groove adapted to the rotating column is provided on the mounting frame, with the rotating column rotatably mounted within the rotating groove.
[0010] As a preferred embodiment, the magnetic suction assembly includes a first magnetic block and a second magnetic block. The first magnetic block is fixedly installed on the back of the mounting bracket, and the second magnetic block is provided in multiple sets and is fixedly installed on the back of multiple sets of indicator seats respectively.
[0011] The technical effects and advantages of this utility model are as follows:
[0012] 1. By setting up a rotating disk with an outer scale, a laser emitting device that can emit lasers, and a clearly directional indicator, the relationship between direction and angle can be displayed intuitively and dynamically. Compared with traditional planar direction diagrams or verbal explanations, students can clearly understand the angular relationship between the directions indicated by different indicator seats, such as the change in angle from east to north, by reading the laser direction of the laser emitting device and the outer and inner scales, and the 90° angle between each direction. This greatly improves the clarity of their understanding of the concept of direction.
[0013] 2. By setting up magnetic components, including a first magnetic block and a second magnetic block, it can be stably attached to magnetic surfaces such as blackboards. Combined with a rotatable laser emitter and an outer scale, teachers can easily operate the rotating disk to display different directions and angles during the teaching process, allowing students to visually and intuitively perceive changes in direction and the numerical values of angles. This makes abstract knowledge of direction and angle more concrete and helps students quickly master the knowledge points. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see the appendix Figure 1 - Appendix Figure 4 This is a magnetic laser compass for mathematics teaching, comprising a rotating disk 1, multiple indicator seats 2, an outer scale 3, a laser emitting device 5, and a magnetic assembly. The indicator seats 2 are evenly distributed around the rotating disk 1 and are used to indicate the basic direction. The outer scale 3 is set on the rotating disk 1. The laser emitting device 5 is set at the center of the rotating disk 1 and is used to emit laser light to indicate the direction. The magnetic assembly is set on the back of the rotating disk 1 and is used to attach the compass to a magnetic surface. All components work together to form a compact teaching tool. The fixed connection between the indicator seats 2 and the rotating disk 1 ensures stable basic direction indication. The central layout of the laser emitting device 5 can achieve 360-degree direction display without blind spots. The back-mounted design of the magnetic assembly does not affect the front teaching view, making the whole device both practical and easy to operate.
[0021] The four indicator seats 2 point to the four basic directions of east, south, west, and north respectively. The outer ring scale 3 is a ring scale with four arrays of 0-90 degrees and is set on the edge of the rotating disk 1. The rotating disk 1 has an inner ring scale 4 with the readings opposite to those on the outer ring scale 3. The inner ring scale 4 on the rotating disk 1 has the readings in the opposite direction, forming a positive and negative relationship. Whichever direction you deviate from, that is the starting scale. The orientation of the four indicator seats 2 is in line with the teaching needs of basic directions in mathematics teaching. The coordinated design of the outer ring scale 3 and the inner ring scale 4 makes the angle reading accurate and intuitive, effectively reducing the difficulty for students to understand the relationship between direction and angle.
[0022] A hollow groove 8 is provided at the center of the rotating disk 1, and a mounting bracket 9 is fixedly installed in the hollow groove 8. The hollow groove 8 reduces the overall weight of the rotating disk 1, provides a stable installation space for the mounting bracket 9, and does not obstruct the visibility of the outer scale 3 and the indicator seat 2, thus taking into account both the portability and structural stability of the device.
[0023] The laser emitting device 5 includes a mounting housing 502 and a laser emitter 503 disposed within the mounting housing 502. A rotating column is fixedly mounted on the bottom of the mounting housing 502. A rotating groove 501 adapted to the rotating column is provided on the mounting bracket 9, and the rotating column is rotatably mounted in the rotating groove 501. The rotating engagement structure between the rotating column and the rotating groove 501 makes the steering operation of the laser emitting device 5 smooth and flexible. The enclosed design of the mounting housing 502 on the laser emitter 503 can protect the internal components and ensure the accuracy of the laser emission direction.
[0024] Specifically, this magnetic laser compass, a mathematical teaching tool, features a rotating disk 1 with an outer scale 3, a laser emitting device 5 that emits laser light, and a clearly directional indicator 2. It can intuitively and dynamically demonstrate the relationship between direction and angle. Compared to traditional planar direction diagrams or verbal explanations, students can clearly understand the angular relationship between the directions indicated by different indicator 2, such as the change in angle from east to north, by observing the laser direction of the laser emitting device 5 and reading the outer scale 3. This greatly enhances the clarity of students' understanding of the concept of direction, effectively solves the problem of difficulty in understanding direction and angle in traditional teaching, and significantly improves teaching effectiveness.
[0025] Please see the appendix Figure 1 - Appendix Figure 3 The magnetic attraction component includes a first magnetic block 6 and a second magnetic block 7. The first magnetic block 6 is fixedly installed on the back of the mounting frame 9. The second magnetic block 7 is provided in multiple sets and is fixedly installed on the back of multiple sets of indicator seats 2 respectively. The first magnetic block 6 and the mounting frame 9 and the second magnetic block 7 and the indicator seat 2 are fixed respectively to form a multi-point adsorption structure, which greatly improves the adsorption stability of the device on the magnetic surface and avoids position displacement caused by collision or shaking during the teaching process.
[0026] Specifically, the compass is equipped with a magnetic component, including a first magnetic block 6 and a second magnetic block 7, which can stably attach to magnetic surfaces such as blackboards. Combined with a rotatable laser emitter 5 and an outer scale 3, teachers can easily operate the rotating disk 1 to display different directions and angles during teaching. This allows students to visually and intuitively perceive changes in direction and the numerical values of angles, making abstract knowledge of direction and angle more concrete. This helps students quickly grasp the knowledge points and overcomes the drawback of traditional teaching methods where students have difficulty understanding due to the limited display methods.
[0027] The working principle of this utility model is as follows: This utility model is a magnetic laser direction indicator for mathematical teaching. First, the first magnetic block 6 on the back of the mounting frame 9 and the second magnetic block 7 on the back of the indicator seat 2 in the magnetic assembly are used to stably attach the entire device to a magnetic teaching surface such as a blackboard. The basic direction is determined by the four indicator seats 2 evenly distributed around the rotating disk 1 and pointing to the east, south, west and north respectively. Then, the mounting frame 9 fixed in the hollow groove 8 in the center of the rotating disk 1 has a rotating groove 501 that matches the rotating column at the bottom of the mounting housing 502 in the laser emitting device 5, so that the laser emitting device 503 in the mounting housing 502 can rotate flexibly. With the help of the outer ring scale 3 on the edge of the rotating disk 1 and the inner ring scale 4 with the opposite reading, the teacher can rotate the laser emitting device 5 to make the laser accurately point to the target direction. Students read the specific angle value through the correspondence between the inner ring scale 4 and the outer ring scale 3, so as to intuitively perceive the angular relationship between the basic directions pointed to by different indicator seats 2, realize the concrete display of abstract direction and angle knowledge, and help students quickly understand and master it. At this point, the whole process is completed.
[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
