[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] The aforementioned related technologies still suffer from several drawbacks, including the scattered and limited functionality of teaching aids, making it difficult to integrate demonstration and simulation operations, resulting in a disjointed teaching process. Furthermore, the height and angle of demonstration equipment are typically fixed, failing to accommodate the usage habits of teachers of different heights and the viewing needs of different teaching scenarios. Physical operation boards (such as business model canvases) used for group discussions and simulation operations are inconvenient to store, occupy a large amount of space, and have a fixed unfolded state, lacking flexibility. The entire teaching equipment is difficult to move, lacking an effective and stable support mechanism, leading to a poor user experience when mobile teaching or fixed use is required. Expensive components such as displays lack effective protective measures, making them prone to dust accumulation or damage during non-use periods. Therefore, to address these issues, this application proposes the following technical solution:

[0035] Reference Figures 1-7 This invention provides a teaching device for university students' innovation and entrepreneurship courses, comprising:

[0036] Base 1, with a lifting component fixedly connected to the top of base 1, and a support platform 2 fixedly connected to the top of the lifting component;

One end of a second threaded rod 13 is fixedly connected to the output end of the second motor 12. The other end of the second threaded rod 13 passes through the sliding plate 9 and is fixedly connected to the inner wall of the cavity 8. The sliding plate 9 and the second threaded rod 13 are threadedly connected.

[0045] In one embodiment of the present invention, the anti-slip plate 11 at the end of the support rod 10 can be pressed down to the ground by the motor drive, so that when teaching needs to be fixed in a fixed position, the main body of the device is stably supported on the ground, effectively preventing movement or shaking caused by accidental contact, and ensuring the stability and safety of the teaching process.

[0046] As an optional implementation, the teaching demonstration component includes several support frames 14, which are fixedly connected to the top of the support platform 2 in the circumferential direction.

[0051] In one embodiment of the present invention, the slider 24 is moved by rotating the third threaded rod 23, which in turn drives the adjusting plate 20 to rotate, thereby achieving angle adjustment.

[0052] As an optional implementation, the connector includes two first connecting blocks 26 fixedly connected to both sides of the bottom end of the magnetic main board 21, a second connecting block 27 fixedly connected to the magnetic sub-board 22, a groove 28 provided on the second connecting block 27, a connector 30 slidably connected in the groove 28 by a spring 29, and a connecting groove 31 provided on the first connecting block 26, the connector 30 being adapted to the connecting groove 31.

[0053] In one embodiment of the present invention, the connector 30 pushed by the spring 29 cooperates with the connecting groove 31, and can automatically lock into place when the sub-plate is unfolded to be flush with the main plate, ensuring the flatness and stability of the operating surface; when folding is required, it can be disassembled with just a little force, making the operation simple and intuitive, and greatly improving the efficiency of teaching preparation and completion.

One end of the adjustment block 36 extends out of the vertical groove 33 and is hinged to a connecting rod 37. The other end of the connecting rod 37 is hinged to the support frame 16.

[0055] In one embodiment of the present invention, the tilt angle of the display screen can be easily changed by driving the hinged linkage mechanism through the electric telescopic rod 34, providing a better viewing angle for students in different positions in the classroom, thereby optimizing the teaching and display effect.

[0056] As an optional implementation, the protective component includes several storage boxes 38, with a winding roller 39 rotatably connected inside the storage box 38. One end of a shielding curtain 40 is fixedly connected to the winding roller 39, and the other end of the shielding curtain 40 extends out of the storage box 38 and is fixedly connected to a hanging ring. A hook is fixedly connected to the bottom of the support frame 14, and the hanging ring and the hook are adapted to each other. The winding roller 39 is connected to the storage box 38 through a spring.

[0057] In one embodiment of the present invention, the screen can be completely covered during non-teaching periods (such as night or holidays) by means of a pull-out and hanging curtain 40, which effectively prevents dust accumulation, scratches from hard objects or accidental bumps.

[0058] As an optional implementation, a rubber anti-slip pad is fixedly connected to the bottom of the anti-slip plate 11.

[0059] In one embodiment of the present invention, the friction between the anti-slip plate 11 and the ground is increased by setting a rubber anti-slip pad, thereby further ensuring stability.
