[0025] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Example 1: Please refer to Figure 1-Figure 7 The utility model provides a technical solution: a demonstration tool, including a mobile box 1, the four corners of the bottom of the mobile box 1 are movably installed with mobile wheels 4, the mobile wheels 4 are composed of wheels and movable seats, the wheels are provided with brake components, and the mobile wheels 4 are prior art and will not be elaborated on here. The right side of the mobile box 1 is fixedly connected with an armrest 5, and the inner cavity of the mobile box 1 is installed with a demonstration mechanism 2;

[0027] The demonstration mechanism 2 includes a projection board 202, a first motor 204 and a second motor 205. The projection board 202 is arranged on the top of the mobile box 1. The surfaces of the first motor 204 and the second motor 205 are fixedly connected to the inner cavity of the mobile box 1. The output end of the first motor 204 is fixedly connected to the first gear 212. The top of the surface of the first gear 212 is meshed with a tooth plate 215. The top of the tooth plate 215 is attached to the connecting plate 203. The front side of the connecting plate 203 is fixedly installed with a demonstration screen 201. The output end of the second motor 205 is fixedly connected to a connecting shaft 216. The surface of the connecting shaft 216 is fixedly connected to a rotating roller 206. The front side of the rotating roller 206 is provided with a connecting groove 209. The inner cavity of the connecting groove 209 is plugged into the right side of the connecting plate 203. The first motor 204 can drive the first gear 212 to rotate, and the rotation of the first gear 212 drives the tooth plate 215 to move toward the back side. The movement of the toothed plate 215 pushes the limiting plate 214 to move, and the movement of the limiting plate 214 drives the connecting plate 203 to move, and the movement of the connecting plate 203 drives the demonstration screen 201 to move, so that the demonstration screen 201 shrinks toward the back side, and at the same time, the right side of the connecting plate 203 is engaged with the interior of the connecting groove 209, so that the connecting plate 203 can rotate synchronously with the connecting groove 209, and then the rotation of the second motor 205 drives the connecting shaft 216 to rotate, and the rotation of the connecting shaft 216 drives the connecting plate 203 to rotate, and the rotation of the connecting plate 203 drives the demonstration screen 201 to rotate, so that the demonstration screen 201 rotates from a vertical state to a horizontal state, until the demonstration screen 201 and the projection board 202 are in the same vertical position, and the work displayed on the demonstration screen 201 can be 3D projected by the projection board 202, thereby increasing the presentation methods of the work and improving the presentation effect.

[0028] As a further limitation of the demonstration mechanism 2 of the present invention, the inner cavity of the tooth plate 215 is slidably connected to the support rod 213, and the surface of the support rod 213 is provided with an anti-slip coating. Both ends of the support rod 213 are fixedly connected to the limit plate 214, and the top of the limit plate 214 is fixedly connected to the bottom of the connecting plate 203, and one side of the limit plate 214 contacts the surface of the tooth plate 215. Through the setting of the support rod 213, the position of the tooth plate 215 is supported, so that the tooth plate 215 can move stably on the bottom of the connecting plate 203. The position of the limit plate 214 is fixed to the position of the support rod 213, ensuring that the tooth plate 215 and the connecting plate 203 rotate synchronously. At the same time, the anti-slip coating provided on the surface of the support rod 213 can keep the tooth plate 215 stationary when not subjected to external force, thereby preventing the tooth plate 215 from shifting during the rotation process, resulting in the tooth plate 215 being unable to engage with the surface of the first gear 212 again after the subsequent connecting plate 203 is reset.

[0029] A guide groove 207 is provided on the left side of the inner cavity of the moving box 1, and a guide rod 210 is slidably connected to the inner cavity of the guide groove 207. The right side of the guide rod 210 is fixedly connected to the left side of the connecting plate 203. Through the setting of the guide groove 207, the surface of the guide rod 210 can slide inside the moving box 1, and then the movement of the guide rod 210 is guided by the guide groove 207, so that the guide rod 210 moves according to the predetermined route, thereby improving the stability of the connecting plate 203 during movement and avoiding position displacement when the connecting plate 203 moves.

[0030] The inner cavity of the guide groove 207 is provided with a limiting groove 208, and the inner cavity of the limiting groove 208 is slidably connected to the limiting ring 211. The inner cavity of the limiting ring 211 is fixedly connected to the surface of the guide rod 210. Through the setting of the limiting ring 211, the guide rod 210 is limited to avoid the guide rod 210 from detaching from the inside of the guide groove 207 during movement, thereby resulting in a lack of effective support and guidance during the rotation of the connecting plate 203, affecting the stability of the connecting plate 203 during rotation.

[0031] The specific implementation of this embodiment is as follows: first, the first motor 204 is started by an external power supply, and the first motor 204 drives the first gear 212 to rotate, and the rotation of the first gear 212 drives the tooth plate 215 to move toward the back side, and the movement of the tooth plate 215 pushes the limit plate 214 to move, and the movement of the limit plate 214 drives the connecting plate 203 to move, and the movement of the connecting plate 203 drives the demonstration screen 201 to move, so that the demonstration screen 201 shrinks toward the back side, and at the same time, the right side of the connecting plate 203 is engaged with the inside of the connecting groove 209, so that the connecting plate 203 can rotate synchronously with the connecting groove 209. During the rotation of the connecting plate 203, the guide rod 210 is driven in the guide The guide rod 210 slides inside the groove 207 and guides the movement of the guide groove 207, so that the connecting plate 203 can move along a predetermined route, thereby preventing the position of the connecting plate 203 from being offset during the movement. Then, the second motor 205 rotates the connecting shaft 216, and the connecting plate 203 rotates through the rotation of the connecting shaft 216. The rotation of the connecting plate 203 also rotates the demonstration screen 201, so that the demonstration screen 201 rotates from a vertical state to a horizontal state until the demonstration screen 201 and the projection board 202 are in the same vertical position. Then, the projection board 202 can perform 3D projection on the work displayed on the demonstration screen 201, thereby increasing the presentation methods of the work and improving the presentation effect.

[0032] Example 2: Please refer to Figure 1-Figure 7 The present invention provides a technical solution: a demonstration tool. The present invention makes corresponding improvements to the technical problems mentioned in the background technology. An adjusting mechanism 3 is installed on the top of the mobile box 1. The adjusting mechanism 3 includes a second gear 306. The inner cavity of the second gear 306 is fixedly connected to the surface of the connecting shaft 216. The back side of the surface of the second gear 306 is meshed and connected with a lifting plate 305. The top of the lifting plate 305 is fixedly connected with an adjusting plate 301. The inner cavity of the adjusting plate 301 is fixedly installed with the surface of the projection plate 202. The right side of the bottom of the adjusting plate 301 is fixedly connected with a supporting plate 307. Adjustment slots 303 are provided on both sides of the inner cavity of the mobile box 1. The inner cavity is slidably connected to the surfaces of the lifting plate 305 and the support plate 307 respectively. Due to the setting of the second gear 306, when the connecting shaft 216 rotates, the second gear 306 will be synchronously driven to rotate. The rotation of the second gear 306 drives the lifting plate 305 to move downward, and the movement of the lifting plate 305 drives the adjustment plate 301 to move. The movement of the adjustment plate 301 drives the projection plate 202 to move, so as to prevent the projection plate 202 from blocking the normal rotation of the demonstration screen 201. After the demonstration screen 201 completes its rotation, the bottom of the projection plate 202 is exactly in contact with the top of the demonstration screen 201, ensuring effective cooperation between the demonstration screen 201 and the projection plate 202.

[0033] As a further limitation of the adjustment mechanism 3 of the present invention, a protective frame 302 is fixedly connected to the bottom of the adjustment plate 301, and a positioning groove 304 is provided on the top of the moving box 1. The surface of the protective frame 302 is slidably connected to the inner cavity of the positioning groove 304. Through the setting of the positioning groove 304, the movement of the protective frame 302 is guided so that the protective frame 302 can maintain vertical movement. At the same time, when the protective frame 302 is reset, the position of the protective frame 302 can be stored to prevent the protective frame 302 from blocking the line of sight of the projection board 202. When the projection board 202 is not in use, the top of the moving box 1 is sealed by the protective frame 302, which can effectively prevent foreign matter from entering the interior of the moving box 1 through the top of the moving box 1, thereby preventing foreign matter from entering and affecting the normal use of the internal parts of the moving box 1.

[0034] The specific implementation of this embodiment is as follows: during the rotation of the demonstration screen 201, the second gear 306 is synchronously driven to rotate by the rotation of the connecting shaft 216, and the rotation of the second gear 306 drives the lifting plate 305 to move downward, and the movement of the lifting plate 305 drives the adjustment plate 301 to move, and the movement of the adjustment plate 301 drives the projection plate 202 to move. This can prevent the position of the projection plate 202 from being fixed and affecting the normal rotation of the demonstration screen 201. After the demonstration screen 201 is rotated into place, the bottom of the projection plate 202 can be exactly attached to the top of the demonstration screen 201, so that the demonstration screen 201 and the projection plate 202 can be used stably together, thereby improving the projection quality of the projection plate 202.

[0035] Example 3: Please refer to Figure 2-Figure 3 The present invention provides a technical solution: a demonstration tool. The present invention makes corresponding improvements to the technical problems mentioned in the background technology. A fixed frame 12 is fixedly connected to the left side of the inner cavity of the mobile box 1. A third motor 6 is fixedly installed on the back side of the fixed frame 12. The output end of the third motor 6 is fixedly connected to a third gear 7. The bottom of the surface of the third gear 7 is meshed with a fourth gear 8. There are two fourth gears 8. A fixed shaft 9 is fixedly connected to the inner cavity of the fourth gear 8. A cleaning roller 10 is fixedly connected to the surface of the fixed shaft 9. A flexible brush 11 is provided on the surface of the cleaning roller 10. One side of the flexible brush 11 contacts the surface of the demonstration screen 201. Through the setting of the third motor 6, the third gear 7 can be driven to rotate. The rotation of the third gear 7 drives the fourth gear 8 to rotate. The rotation of the fourth gear 8 drives the fixed shaft 9 to rotate. The rotation of the fixed shaft 9 drives the cleaning roller 10 to rotate. The rotation of the cleaning roller 10 drives the flexible brush 11 to clean some dust on the surface of the demonstration screen 201 to avoid affecting the projection effect of the projection board 202.

[0036] The specific implementation of this embodiment is as follows: during the use of the demonstration screen 201, it needs to frequently come into contact with hands or external objects, which causes dust to easily adhere to the surface of the demonstration screen 201. Before projecting the work displayed on the demonstration screen 201, the third motor 6 is first started by an external power supply. During the rotation of the demonstration screen 201, the third motor 6 drives the third gear 7 to rotate, and the rotation of the third gear 7 simultaneously drives the two fourth gears 8 to rotate clockwise. When the flexible brush 11 contacts the surface of the demonstration screen 201, it can push the dust on the surface of the demonstration screen 201 to the front side, thereby cleaning the dust on the surface of the demonstration screen 201 and preventing dust from adhering to the surface of the demonstration screen 201 and reducing the projection quality of the projection board 202.

[0037] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention as claimed.
