DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-2 In this embodiment, a surface rotation demonstration device for advanced mathematics that is easy to adjust the curvature includes a base plate 1, a sponge pad is fixed to the bottom of the base plate 1, and the stability of the support of the base plate 1 can be effectively improved by setting the sponge pad. Two support blocks 2 are fixed to the top of the base plate 1, and a top plate 3 is fixed to the top of the support block 2. A driving motor 4 is fixed to the top of the base plate 1, and a driving rod 5 that passes through the top of the top plate 3 is fixed to the output shaft of the driving motor 4. Two adjusting components 6 are arranged on the outer surface of the driving rod 5, and connecting plates 7 are fixed to the left and right sides of the adjusting component 6. The adjusting component 6 is used to adjust the position of the connecting plate 7.

[0023] In addition, a connecting plate 8 is fixed to the outer surface of the driving rod 5, and a plurality of fixing clips 9 are fixed to the front of the connecting plate 8 and the connecting plate 7, and the fixing clips 9 are used to fix the luminous rubber belt. A battery 10 is fixed between the top plate 3 and the bottom plate 1, and the battery 10 is used to store electricity, so that the whole can be used normally in an environment without electricity. An identification plate is fixed to the front of the battery 10, and two supporting components are slidably connected inside the bottom plate 1, and the supporting component includes a limit block 11 fixed to the bottom plate 1. The bottom plate 1 is internally slidably connected with an extension block 12 that extends to the outside of the bottom plate 1. By pulling the extension block 12, the length of the bottom plate 1 can be increased, thereby making the support of the bottom plate 1 more stable. A stabilizing block 13 is fixed to the bottom of the extension block 12, and a limiting plate is fixed to the front of the extension block 12. A limiting groove that is slidably connected to the limiting plate is provided inside the bottom plate 1, and no limiting groove is provided inside the limiting block 11, so that the limiting plate cannot pass through the limiting block 11, and thus the extension block 12 cannot be separated from the bottom plate 1. The support assembly is used to improve the overall stability.

[0024] In general, by pulling the extension block 12, the length of the base plate 1 can be extended, thereby making the contact area between the base plate 1 and the support larger, effectively improving the stability of the support, so that it is not easy to shake during subsequent rotation, and effectively improving the overall practicality.

[0025] See also Figure 3 The adjusting assembly 6 in this embodiment includes a moving block 601 threadedly connected to the driving rod 5, and the two moving blocks 601 are rotatably connected to the opposite sides thereof with a connecting block 602 slidably connected to the driving rod 5, and the two connecting blocks 602 are fixed with an extension block slidably connected to the moving block 601 on the opposite sides thereof, and an extension plate slidably connected to the moving block 601 is fixed to the outer surface of the extension block, and the moving block 601 can push the connecting block 602 to move by means of the setting of the extension block and the extension plate, while the rotation of the moving block 601 will not affect the connecting block 602, and sliding blocks are fixed to the left and right side walls of the inner cavity of the connecting block 602, and a sliding groove slidably connected to the sliding block is provided inside the driving rod 5, and the setting of the sliding block can stably push the connecting block 602 to rotate together when the driving rod 5 rotates.

[0026] Furthermore, the right side of the moving block 601 is threadedly connected to the extrusion block 603, and a threaded strip is fixed on the outer surface of the extrusion block 603. A threaded hole compatible with the threaded strip is opened on the right side of the moving block 601. When the extrusion block 603 and the driving rod 5 are extruded, the friction between the moving block 601 and the driving rod 5 will be increased, thereby effectively fixing the driving rod 5 and the moving block 601. A control block 604 is fixed on the right side of the extrusion block 603, and a friction strip is fixed on the outer surface of the control block 604. An extrusion pad is fixed on the left side of the extrusion block 603.

[0027] In general, when the extrusion block 603 is away from the driving rod 5, the movable block 601 can be rotated to make the movable block 601 push the connecting block 602 to move, thereby moving the connecting plate 7, and pulling the luminous rubber belt to adjust the curvature, thereby effectively improving the overall practicality.

[0028] The electrical components appearing in the text are all electrically connected to the controller and the power supply. The control method of the utility model is controlled by the controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power supply is also common knowledge in this field. The utility model is mainly used to protect mechanical devices, so the utility model will no longer explain the control method and circuit connection in detail.

[0029] The working principle of the above embodiment is:

[0030] (1) When the luminous rubber belt is fixed by the fixing clip 9, the fixing clip 9 at different positions can be selected to form curved surfaces with different curvatures. When the extrusion block 603 is rotated by rotating the control block 604, the extrusion block 603 will be moved away from the driving rod 5 due to the extrusion of the thread, thereby causing the moving block 601 to lose its fixation with the driving rod 5. At this time, the control block 604 can be pushed to cause the moving block 601 to rotate along the driving rod 5, so that the moving block 601 pushes the connecting block 602 to move due to the extrusion of the thread, thereby pulling the luminous rubber belt to further adjust the curvature, thereby effectively increasing the adjustment range, allowing different styles of curves to be formed, and effectively improving the overall practicality.

[0031] (2) When rotation is required, the control block 604 is rotated again so that the squeezing block 603 contacts and squeezes the driving rod 5, thereby fixing the moving block 601. At this time, the driving motor 4 is started to rotate the driving rod 5, the connecting block 602, the connecting plate 8, the connecting plate 7 and the moving block 601 together, thereby driving the luminous rubber belt on the fixing clamp 9 to rotate to form a curved surface, so that students can better understand it and effectively improve the overall practicality.

[0032] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0033] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention.
