However, in practical applications of existing 3D world maps, the lines displaying key information such as latitude and longitude or national borders are often designed to be quite thin. This makes it particularly difficult for students at a distance to observe details, thus affecting the effectiveness of history teaching. Summary of the Invention

[0003] This disclosure relates to a rotatable three-dimensional world map to address the problem that in practical applications of existing three-dimensional world maps, the lines displaying key information such as latitude and longitude or national borders are often designed to be quite thin, making it particularly difficult for students at a distance to observe details and affecting the effectiveness of history teaching.

[0004] In a first aspect, this disclosure provides a rotatable three-dimensional world map, specifically comprising: a counterweight fixing base, the counterweight fixing base having a circular structure, a storage tank installed at the bottom of the counterweight fixing base, and a support body installed at the top of the counterweight fixing base, with a scale bracket installed at the top of the support body; the scale bracket having an arc-shaped structure, with an upper positioning block rotatably mounted at the top of the scale bracket; a sphere installed at the bottom of the upper positioning block; a lower positioning block installed at the bottom of the sphere, and multiple marking micro-holes opened on the outer surface of the sphere; and a color-transparent film installed inside the marking micro-holes.

[0005] Furthermore, magnetic blocks are installed on both sides of the counterweight fixing seat, and a protective cover is installed on the outer side of the counterweight fixing seat; the protective cover is made of flexible material, and after the protective cover is unfolded, it is located on the outside of the sphere, and a light spring is installed inside the side wall of the protective cover.

[0006] Furthermore, a traction ring is installed on the top of the lightweight spring and the protective cover; the traction ring is a ring structure, the inner side of the traction ring is attached to the outer side of the magnetic block, and a cover plate is installed on the top of the traction ring; the cover plate can also be placed in the storage tank at the bottom of the counterweight fixing seat.

[0007] Furthermore, a rotating shaft is rotatably mounted on the inner side of the lower positioning block; the bottom of the rotating shaft is rotatably mounted on the bottom of the scale bracket, and four positioning grooves are provided on the outer side of the rotating shaft.

[0008] Furthermore, each of the four positioning slots has a slidably mounted retaining plate inside; the inner side of the retaining plate has an inclined structure, and the outer side of the retaining plate is mounted on the inner side of the lower positioning block.

[0009] Furthermore, a drive rod is rotatably mounted at the bottom of the rotating shaft; a push plate is rotatably mounted at the top of the drive rod; the bottom of the push plate has a conical structure, and the push plate is slidably mounted on the inner side of the clamping plate.

[0010] Furthermore, the upper positioning block is a cylindrical structure, and a damping block is installed on the inner side of the upper positioning block; an adjusting rod is slidably installed at the middle position of the damping block; a drive cylinder is installed at the inner end of the adjusting rod, and a drive cylinder control module is installed at the outer end of the adjusting rod, and an illumination lamp is installed on the output end of the drive cylinder at the inner end of the adjusting rod; the illumination lamp is located inside the sphere.

[0011] This invention provides a rotatable three-dimensional world map, which has the following beneficial effects:

[0012] In use, this invention increases the clarity of observation by allowing light to pass through the micro-holes along different paths. When using a three-dimensional world map in history teaching, different micro-holes are distributed on the side of the sphere. These micro-holes are located on key lines on the map, such as latitude and longitude lines or national borders. Inside each micro-hole is a translucent membrane with different paths. Adjusting the lever moves the illumination lamp inside the sphere, allowing light to pass through the micro-holes. The light from multiple points can mark important lines on the map, making it easier for students at a distance to view. Furthermore, the light shining on a flat wall magnifies the map, enhancing students' learning enjoyment and accelerating the progress of history teaching.

[0013] Furthermore, the rotation speed of the 3D world map can be adjusted by adjusting the position of the push plate. When using the 3D world map in history teaching, depending on the different teaching habits of different teachers, the drive rod at the bottom of the lower positioning block is rotated to drive the push plate to push the card plate to apply pressure. This changes the friction between the outer side of the card plate and the inner side of the lower positioning block. Therefore, the rotation speed of the lower positioning block can be adjusted when it rotates on the outer side of the rotation axis. After increasing the frictional resistance, it can prevent the ball from rotating too fast and can accurately and quickly locate the position to be learned. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] Please refer to Figures 1 to 6 :

[0029] Example 1:

[0030] This utility model proposes a rotatable three-dimensional world map, comprising: a counterweight fixing base 1, which is circular in structure, with a storage tank installed at the bottom of the counterweight fixing base 1, and a support body 101 installed at the top of the counterweight fixing base 1, with a scale bracket 102 installed at the top of the support body 101; the scale bracket 102 is arc-shaped, and an upper positioning block 103 is rotatably installed at the top of the scale bracket 102; magnetic blocks 104 are installed on both sides of the counterweight fixing base 1, and anti-magnetic blocks are installed on the outer side of the counterweight fixing base 1. The protective cover 105 is made of flexible material and is located outside the sphere 2 after being unfolded. A lightweight spring 106 is installed inside the side wall of the protective cover 105. A traction ring 107 is installed on the top of the lightweight spring 106 and the protective cover 105. The traction ring 107 is a ring structure. The inner side of the traction ring 107 is attached to the outer side of the magnetic block 104, and a cover plate 108 is installed on the top of the traction ring 107. The cover plate 108 can also be placed in the storage tank at the bottom of the counterweight fixing seat 1.

[0031] In this embodiment, when using a three-dimensional world map during history teaching, the top of the support 101 supports the scale bracket 102. The top of the scale bracket 102 can position the rotating sphere 2, allowing the sphere 2 to rotate. After use, the traction ring 107 is pushed upward on the outside of the counterweight fixing seat 1. After the inner side of the traction ring 107 loses the attraction of the magnetic block 104, it is driven to move upward by the action of the light spring 106. Under the traction of the traction ring 107, the protective cover 105 unfolds and is located outside the sphere 2. The cover plate 108 placed in the storage groove at the bottom of the counterweight fixing seat 1 is taken out and closed and installed on the traction ring 107, so that the sphere 2 is inside the protective cover 105, reducing external dust and preventing the text and other information on the world map from fading due to sunlight.

[0032] In Example 2, based on Example 1, a sphere 2 is installed at the bottom of the upper positioning block 103; a lower positioning block 201 is installed at the bottom of the sphere 2; a rotating shaft 202 is rotatably installed on the inner side of the lower positioning block 201; the bottom of the rotating shaft 202 is rotatably installed on the bottom of the scale bracket 102, and four positioning slots 203 are provided on the outer side of the rotating shaft 202; a locking plate 204 is slidably installed inside each of the four positioning slots 203; the inner side of the locking plate 204 has an inclined structure, and the outer side of the locking plate 204 is installed on the inner side of the lower positioning block 201; a drive rod 205 is rotatably installed at the bottom of the rotating shaft 202; a push plate 206 is rotatably installed at the top of the drive rod 205; the bottom of the push plate 206 has a conical structure, and the push plate 206 is slidably installed on the inner side of the locking plate 204. When using a three-dimensional world map in the process of history teaching... When the ball 2 is in motion, the top and bottom of the ball 2 drive the upper positioning block 103 and the lower positioning block 201 to rotate, causing the lower positioning block 201 to rotate on the outer side of the top of the rotating shaft 202. The rotating drive rod 205 at the bottom of the rotating shaft 202 drives the push plate 206 at its inner end to move inside the four clamping plates 204, causing the push plate 206 to move downward and push the clamping plate 204 to move outward inside the positioning groove 203. This causes the outer side of the clamping plate 204 to apply pressure to the inner side of the lower positioning block 201, changing the friction between the outer side of the clamping plate 204 and the inner side of the lower positioning block 201. Therefore, the rotation speed of the ball 2 can be adjusted. Increasing the friction can reduce the problem of the ball 2 rotating too fast, allowing for quick positioning of the required position without arbitrarily changing it. This adaptability is strong and can accommodate the operating habits of different teachers.

[0033] In Example 3, based on Example 1, multiple marking micro-holes 3 are opened on the outer surface of the sphere 2; a transparent film 301 is installed inside the marking micro-holes 3; the upper positioning block 103 has a cylindrical structure, and a damping block 302 is installed on the inner side of the upper positioning block 103; an adjusting rod 303 is slidably installed at the middle position of the damping block 302; a drive cylinder is installed at the inner end of the adjusting rod 303, and a drive cylinder control module is installed at the outer end of the adjusting rod 303; an illumination lamp 304 is installed on the output end of the drive cylinder at the inner end of the adjusting rod 303; the illumination lamp 304 is located inside the sphere 2. When using a three-dimensional world map in the process of history teaching, multiple tiny marking micro-holes 3 are distributed on the sphere 2, and different marking micro-holes 3 are installed inside the marking micro-holes 3. The colored transparent film 301 can mark the latitude and longitude, as well as national borders, on the world map on the sphere 2. Moving the outer end of the adjusting rod 303 causes the drive cylinder at the inner end of the adjusting rod 303 to move inside the sphere 2. The damping block 302 increases the sliding friction of the adjusting rod 303, preventing the adjusting rod 303 from moving randomly after it stops moving. The drive cylinder is controlled by the control module on the outer end of the adjusting rod 303, which drives the illumination lamp 304 to approach the marking micro-hole 3. The light emitted through the marking micro-hole 3 makes it easier for students at a distance to clearly observe the world map. Furthermore, the light emitted through the marking micro-hole 3 onto a flat wall surface can magnify the map, increasing the enjoyment of history learning.

[0034] The working principle of this embodiment is as follows: During use, the top and bottom of the sphere 2 drive the upper positioning block 103 and the lower positioning block 201 to rotate, respectively. The lower positioning block 201 rotates on the outer side of the top of the rotating shaft 202. The rotating drive rod 205 drives the push plate 206 at its inner end to move inside the four clamping plates 204. The push plate 206 moves downward and pushes the clamping plates 204 to move outward in the positioning groove 203. The outer side of the clamping plate 204 applies pressure to the inner side of the lower positioning block 201, and the friction between the outer side of the clamping plate 204 and the inner side of the lower positioning block 201 changes, thereby adjusting the rotation speed of the sphere 2 to suit the operating habits of different teachers. The sphere 2 has multiple tiny marking micro-holes 3, and different colored transparent films 301 are installed inside the marking micro-holes 3, which can display the latitude and longitude of the world map on the sphere 2. The map includes lines such as degrees and national borders. Moving the outer end of the adjusting rod 303 moves the inner drive cylinder within the sphere 2. The damping block 302 increases the sliding friction of the adjusting rod 303. The drive cylinder moves the illumination lamp 304 closer to the marking micro-hole 3. The light emitted through the marking micro-hole 3 allows students at a distance to clearly observe the world map. After use, the traction ring 107 is moved upwards from the outside of the counterweight fixing seat 1. The inner side of the traction ring 107 loses the attraction of the magnetic block 104 and, under the action of the light spring 106, moves upwards. Under the traction of the traction ring 107, the protective cover 105 unfolds, and the cover plate 108 closes and is installed on the traction ring 107. The sphere 2 is inside the protective cover 105, reducing the problem of fading of text and other information on the world map due to sunlight.
