Its core is a high-precision multi-touch screen that displays teaching materials through the display, making it easier for teachers to demonstrate and students to observe. Through an interactive method that combines virtual and real, it transforms abstract theories into visual experiences, enhancing artistic perception and creativity.

[0003] In the prior art, in conventional teaching scenarios, common interactive demonstration devices usually use an integrated support leg structure to support the display screen. The main purpose of this design is to raise the display screen to a suitable height, so that the teacher can interact with the audience more naturally and smoothly during the lecture. However, the design of this integrated support leg is poor in flexibility. When conducting outdoor study activities, the ground conditions of the activity venue are often more complicated, usually rugged, with various ups and downs, potholes or slopes. The integrated support leg has a fixed structure and lacks sufficient adjustment ability. When facing such a ground environment, it is difficult to keep the display screen stable and balanced. This will not only affect the demonstration effect, causing the picture to shake and tilt, interfering with the audience's viewing experience, but may also cause damage to the equipment itself, increase the cost of use and safety risks. Therefore, it is necessary to improve an interactive demonstration device for art education to solve the above problems. Utility Model Content

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] See also Figures 1-6 The utility model provides an embodiment: an interactive demonstration device for art education, including a display screen body 1 and a handle 4, and also includes a hinge seat 21 and a folding mechanism. One end of the display screen body 1 is provided with a handle 4 for carrying the display screen body 1, and the end of the display screen body 1 away from the handle 4 is fixedly connected to the hinge seat 21, and a support leg 22 is rotatably connected to the hinge seat 21, and a limit plate 23 is fixedly connected to the support leg 22, and an extension plate 24 is slidably connected to the limit plate 23. One end of the extension plate 24 is fixedly connected to a positioning plate 25, and a one-way threaded rod 26 is slidably connected to the positioning plate 25. One end of the one-way threaded rod 26 is fixedly connected to an anti-slip pad 27 The one-way threaded rod 26 adjusts the anti-slip pad 27 to rise and fall in contact with the ground, and the flip support leg 22 rotates on the hinge seat 21. The support leg 22 can be folded or unfolded as needed. The support leg 22 contacts the ground with the limit plate 23 and the extension plate 24, and the extension plate 24 slides and extends. Then the one-way threaded rod 26 rises and falls to drive the anti-slip pad 27 to contact the ground. The position of the anti-slip pad 27 is appropriately adjusted according to the use environment. The display screen body 1 is level to avoid tilting. When the support leg 22 is folded, it is positioned by the folding mechanism, so that the display screen body 1 is convenient to carry by the handle 4. The display screen body 1 is a touch-sensitive display screen, which is well known to technicians in this technical field, so it will not be described in detail.

[0024] See also Figure 1-Figure 5The one-way threaded rod 26 is provided with a through hole in the positioning plate 25, and a groove corresponding to the through hole is provided on the one-way threaded rod 26, and the one-way threaded rod 26 slides inside the through hole through the groove. The groove cooperates with the through hole so that the one-way threaded rod 26 will not rotate with the nut 214 when it rotates, so that the one-way threaded rod 26 can be adjusted to rise and fall by twisting the nut 214. The limiting plate 23 is provided with a sliding groove at the corresponding position of the extension plate 24, and the extension plate 24 slides inside the sliding groove. The sliding groove makes the extension plate 24 only slide in a straight line to avoid separation, and the extension plate 24 corresponds to the bottom surface position of the limiting plate 23, and can contact the ground at the same time, thereby providing a stable support. The supporting leg 22 is threadedly connected with a bolt 28, and the limiting plate 23 is rotatably connected to the rotating rod 29. One end of the rotating rod 29 is fixedly connected to the first bevel gear 210, and the meshing portion on the first bevel gear 210 The second bevel gear 211 is combined with a two-way threaded rod 212, which is fixedly connected to the second bevel gear 211. The two-way threaded rod 212 is threadedly connected to the extension plate 24. The two-way threaded rod 212 is rotatably connected to the limit plate 23, and the positioning plate 25 is rotatably connected to the limit ring 213. One end of the limit ring 213 is fixedly connected to a nut 214, and the nut 214 is threadedly connected to the one-way threaded rod 26. By rotating the rotating rod 29, the positions of the two extension plates 24 can be synchronously adjusted, which makes adjustment more convenient and the lifting and lowering of the anti-slip pad 27 more flexible. It can be adjusted according to the use environment. A threaded hole is provided on the support leg 22, and a through hole is provided on the hinge seat 21. The bolt 28 is threaded through the through hole and is threadedly connected to the inside of the threaded hole. There are two through holes. The support leg 22 can be positioned in a folded or unfolded state by passing through the corresponding through holes to prevent the support leg 22 from swinging on its own.

[0025] See also Figure 1 、 Figure 6 The folding mechanism includes a mounting plate 31, which is fixedly connected to one side of the display screen body 1. A limiting rod 32 is fixedly connected to one side of the mounting plate 31. A baffle 33 is fixedly connected to the limiting rod 32 on the side away from the mounting plate 31. A block 34 for positioning the support leg 22 is slidably connected to the limiting rod 32. The block 34 is clamped on the support leg 22. A spring 35 is fixedly connected between the block 34 and the mounting plate 31. When the support leg 22 is folded, the spring 35 pushes the block 34 to clamp the support leg 22, which can prevent the support leg 22 from loosening or swinging, thereby preventing the display screen body 1 from being bumped or damaged. The support leg 22 is provided with a slot at the corresponding position of the block 34, and the block 34 is clamped inside the slot, so that the block 34 has a certain amount of activity space, so that the block 34 can automatically position the support leg 22 through the spring 35.

[0026] When used outdoors, the rotating rod 29 is twisted according to the terrain when placed, and the rotating rod 29 drives the first bevel gear 210, the first bevel gear 210 drives the second bevel gear 211, and the second bevel gear 211 drives the bidirectional threaded rod 212. The bidirectional threaded rod 212 rotates to slide the extension plate 24, and the extension plate 24 slides to cooperate with the limiting plate 23 to expand the contact area with the ground. At the same time, the position of the anti-slip pad 27 can be adjusted. If the ground is concave, the nut 214 is twisted to drive the one-way threaded rod 26 to slide. The nut 214 is limited by the limiting ring 213, and the one-way threaded rod 26 slides to drive the anti-slip pad 27 to descend, so that the anti-slip pad 27 contacts the concave The ground is provided to support the display screen body 1. The display screen body 1 can be connected to an external car power supply or a generator. When not in use, the rotating rod 29 is rotated in the opposite direction to retract the extension plate 24, and then the bolt 28 is unscrewed. At this time, the support leg 22 can be rotated on the hinge seat 21, and then the support leg 22 is squeezed to squeeze the block 34. The block 34 is limited by the limiting rod 32 and the baffle 33. The block 34 compresses the spring 35 while sliding, and then waits for the card slot of the support leg 22 to correspond to the position of the card block 34. The spring 35 resets the card block 34 and snaps it into the inside of the card slot, so that the support leg 22 can be positioned, so that the display screen body 1 can be carried by the handle 4.

[0027] Through the above steps, the sliding cooperation limit plate 23 of the extension plate 24 can flexibly adjust the contact area with the ground when placed. When encountering a recessed position, the one-way threaded rod 26 can drive the anti-slip pad 27 to descend and contact the recessed position, thereby providing stable support to solve the problem that the integrated support leg 22 is difficult to maintain balance on uneven ground during outdoor study.
