Description

Technical Field

[0001] This invention relates to the field of teaching aids technology, and in particular to an internet-based teaching aid. Background Technology

[0002] Internet-based teaching aids refer to a general term for various hardware devices and related software systems that provide support, assistance and optimization for educational activities based on Internet technology. These devices aim to improve teaching quality and efficiency, meet the diverse needs of modern education, and display information on screens to support teachers and students in conducting effective learning activities. Some displays need to be installed on the podium. When teachers use the displays for teaching, it can reduce their writing burden and thus alleviate their fatigue.

[0003] In existing technology, when installing a display screen on the curved protrusion of the podium, it is necessary to drill holes in the curved surface of the protrusion beforehand, and then fix the display screen with screws. However, fixing with screws requires the use of external tools, which takes a lot of time and affects installation efficiency. Furthermore, the position of the display screen cannot be adjusted after installation, which causes students on both sides to be unable to see the content of the display screen clearly due to glare during teaching, thus affecting the teaching quality. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of the prior art by proposing an internet-based teaching aid.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: an Internet-based teaching auxiliary device, including a podium, a clamping mechanism being provided at one end of the podium, and a position adjustment mechanism being provided on the clamping mechanism; The clamping mechanism includes an arc-shaped plate, with an arc-shaped hanging plate fixedly connected to the top of one end of the arc-shaped plate. The shape between the arc-shaped hanging plate and the arc-shaped plate is adapted to the arc-shaped top of the podium. Threaded rods are rotatably connected to both sides of the bottom end of the arc-shaped plate. Clamping plates are threaded to the outer walls of the two threaded rods. The shape of the clamping plates is adapted to the arc-shaped bottom of the podium. Two rows of fixed cones are fixedly connected to the top of the clamping plates. The position adjustment mechanism includes an arc-shaped frame fixedly connected to the end of the arc-shaped plate away from the podium. A support column is provided on the inner wall of the arc-shaped frame. A display screen is connected to the top of the support column through an installation mechanism. The support column moves in an arc and moves the display screen synchronously.

[0006] Preferably, the clamping mechanism further includes fixed columns symmetrically fixedly connected to the bottom of the arc-shaped plate at the end away from the podium. Each of the two fixed columns has a telescopic groove at the end near the podium. Each of the inner walls of the two telescopic grooves is slidably connected to a limit column. A spring is fixedly connected between the two sets of limit columns and the telescopic grooves.

[0007] Preferably, a plurality of guide posts are fixedly connected between the bottom end of the arc-shaped plate and the threaded rod, each guide post penetrating the clamping plate, and a knob is fixedly connected to the bottom end of each of the two threaded rods.

[0008] Preferably, both ends of the support column are provided with grooves, and the inner walls of the two grooves are provided with multiple spherical grooves. Each spherical groove is provided with a ball bearing, and each ball bearing is in contact with the arc-shaped frame.

[0009] Preferably, the position adjustment mechanism further includes fixed plates fixedly connected to both ends of the arc-shaped frame. The top of each of the upper fixed plates is rotatably connected to a drive shaft, and a winding drum is fixedly connected to the outer wall of each of the two drive shafts. A drive motor is fixedly connected to the bottom of each of the lower fixed plates. The drive ends of the two drive motors are fixedly connected to the two drive shafts respectively. Steel wire ropes are wound around the outer wall of each of the two winding drums, and each of the two steel wire ropes is fixedly connected to a support column.

[0010] Preferably, square holes are provided between the fixed plates at both ends of the arc-shaped frame, and fixed shafts are fixedly connected to both sides of the inner wall of the two square holes. Pulleys are rotatably connected to the outer walls of the two sets of fixed shafts. A gap is left between the two sets of pulleys, which is smaller than the diameter of the wire rope, and the wire rope is limited. A connecting block is fixedly connected to the end of the support column near the arc-shaped plate, and the connecting block and the arc-shaped plate are slidably connected.

[0011] Preferably, the installation mechanism includes a crossbar seat fixedly connected to the top of the support column, the top of the crossbar seat having multiple circular insertion holes, and the bottom of the display screen having multiple circular insertion posts fixedly connected, with each circular insertion post and each circular insertion hole having a matching shape.

[0012] Preferably, the top center of the crossbar seat has an installation groove, and a square locking post is inserted through the end of the crossbar seat near the podium and extends into the installation groove. A square tension plate is fixedly connected to one end of the square locking post, and a tension spring is fixedly connected between the square tension plate and the crossbar seat.

[0013] Preferably, a mounting post is fixedly connected to the bottom center of the display screen. The shape of the mounting post and the mounting groove are adapted to each other. A square slot is opened at one end of the mounting post, and the square slot is inserted into the square slot to fix the mounting post.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. Through the clamping mechanism, the arc-shaped hanging plate can be hung on the top of the arc-shaped boss, and the arc-shaped plate is close to the arc-shaped surface of the boss. Then, by rotating the threaded rod, the fixed cone contacts the bottom of the arc-shaped boss until the limit rod pops out from the telescopic groove, thus completing the limit of the clamping plate. This allows the bracket used for the display screen to be quickly installed on the podium, improving installation efficiency. 2. The position adjustment mechanism allows the two winding drums on both sides to rotate synchronously, with one winding drum in the winding state and the other winding drum in the unwinding state. At this time, the support column moves along the arc of the curved frame, thereby changing the position of the support column and the position of the display screen. This allows students on both sides to see the content on the display screen, thus improving the teaching quality. 3. The installation mechanism allows the display screen and the bracket to be separated. After the bracket is installed and fixed, the display screen can be assembled and installed using the cooperation of the mounting columns and mounting slots. This prevents the display screen from shaking and colliding during bracket installation, thereby improving safety. Attached Figure Description

[0017] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0018] like Figures 1-10 The illustrated internet-based teaching aid includes a lectern 1, with a clamping mechanism at one end of the lectern 1 and a position adjustment mechanism on the clamping mechanism. The clamping mechanism allows the bracket to be quickly installed and fixed on the lectern 1, thereby improving installation efficiency. The position adjustment mechanism allows the position of the display screen 10 to be changed, so that students on both sides can see the content on the display screen 10. like Figure 2 , Figure 3 As shown, the clamping mechanism includes an arc-shaped plate 3, an arc-shaped hanging plate 2 is fixedly connected to the top of one end of the arc-shaped plate 3, the shape between the arc-shaped hanging plate 2 and the arc-shaped plate 3 is adapted to the arc-shaped top of the podium 1, threaded rods 18 are rotatably connected to both sides of the bottom end of the arc-shaped plate 3, and clamping plates 4 are threadedly connected to the outer walls of the two threaded rods 18. The shape of the clamping plates 4 is adapted to the arc-shaped bottom of the podium 1, and two rows of fixed cones 16 are fixedly connected to the top of the clamping plates 4. like Figure 1 , Figure 2 As shown, the position adjustment mechanism includes an arc-shaped frame 6 fixedly connected to the end of the arc-shaped plate 3 away from the podium 1. A support column 8 is provided on the inner wall of the arc-shaped frame 6. The top of the support column 8 is connected to the display screen 10 through an installation mechanism. The support column 8 moves in an arc and moves the display screen 10 synchronously. A connecting block 7 is fixedly connected to the end of the support column 8 near the arc-shaped plate 3. The connecting block 7 and the arc-shaped plate 3 are slidably connected. The installation mechanism can separate the display screen 10 from the bracket, so that they can be assembled separately and prevent damage to the display screen 10 during installation.

[0019] like Figure 1 , Figure 3 , Figure 4As shown, the clamping mechanism also includes fixed posts 5 symmetrically fixedly connected to the bottom of the arc-shaped plate 3 at the end away from the podium 1. Each of the two fixed posts 5 has a telescopic groove 23 at the end near the podium 1. Limiting posts 21 are slidably connected to the inner walls of both telescopic grooves 23. Springs 22 are fixedly connected between the two sets of limiting posts 21 and the telescopic grooves 23. The limiting posts 21 and the telescopic grooves 23 are connected by sliding grooves and sliders, and the shapes of the telescopic grooves 23 and the limiting posts 21 are adapted to each other. The elasticity of the springs 22 allows the limiting posts 21 to automatically pop out.

[0020] like Figure 3 As shown, multiple guide posts 20 are fixedly connected between the bottom end of the arc-shaped plate 3 and the threaded rod 18. Each guide post 20 penetrates the clamping plate 4, and a knob 19 is fixedly connected to the bottom end of each of the two threaded rods 18. The guide posts 20 prevent the clamping plate 4 from shifting during clamping, ensuring the clamping effect. By rotating the knob 19, the threaded rod 18 is rotated, and the threaded effect of the threaded rod 18 can move the clamping plate 4 upward, completing the clamping operation.

[0021] like Figure 1 , Figure 6 As shown, the support column 8 has grooves 31 at both ends, and multiple spherical grooves 32 are formed on the inner wall of each groove 31. Each spherical groove 32 has a ball bearing 30 on its inner wall, and each ball bearing 30 is in contact with the arc-shaped frame 6. When the support column 8 moves, the ball bearing 30 rolls in the spherical groove 32, thereby reducing the resistance during movement and making the support column 8 move more smoothly.

[0022] like Figure 2 , Figure 3 , Figure 9 As shown, the position adjustment mechanism also includes fixed plates 15 fixedly connected to both ends of the arc-shaped frame 6. A drive shaft 17 is rotatably connected to the top of each upper fixed plate 15, and a winding drum 13 is fixedly connected to the outer wall of each of the two drive shafts 17. A drive motor 12 is fixedly connected to the bottom of each lower fixed plate 15. The drive ends of the two drive motors 12 are fixedly connected to the two drive shafts 17 respectively. Steel wire ropes 11 are wound around the outer walls of each of the two winding drums 13, and both steel wire ropes 11 are fixedly connected to the support column 8. The drive motors 12 on both sides are controlled to operate synchronously by a synchronous controller. The drive motors 12 drive the drive shafts 17 on both sides to rotate synchronously, thereby rotating the winding drums 13. At this time, one winding drum 13 is in the winding state, and the other is in the unwinding state, so that one of the steel wire ropes 11 on both sides is in the winding state and the other is in the unwinding state. Therefore, the support column 8 can be moved, thereby changing the position of the display screen 10, making it easier for students on both sides to view the content on the display screen 10 and improving teaching quality.

[0023] like Figure 5 , Figure 10As shown, square holes 27 are provided at both ends of the arc-shaped frame 6 between the fixed plates 15. Fixed shafts 26 are fixedly connected to both sides of the inner walls of the two square holes 27. Pulleys 28 are rotatably connected to the outer walls of the two sets of fixed shafts 26. A gap, smaller than the diameter of the wire rope 11, is left between the two sets of pulleys 28, thus limiting the movement of the wire rope 11. The fixed shafts 26 are fixed through the square holes 27. Since the pulleys 28 rotate on the fixed shafts 26, when the wire rope 11 is in the coiled state, it contacts one of the pulleys 28. When the wire rope 11 is being wound or unwound, it rotates the pulley 28 along with it. Therefore, friction on the wire rope 11 is reduced, thereby reducing wear and extending its service life.

[0024] like Figure 6 , Figure 7 As shown, the installation mechanism includes a crossbar seat 9 fixedly connected to the top of the support column 8. Multiple circular insertion holes 35 are provided at the top of the crossbar seat 9. Multiple circular insertion posts 29 are fixedly connected to the bottom of the display screen 10. The shape of each circular insertion post 29 is adapted to each circular insertion hole 35. During installation, the circular insertion posts 29 are inserted into the circular insertion holes 35. Due to the adapted shapes, gaps are avoided after installation, preventing wobbling.

[0025] like Figure 7 , Figure 8 As shown, a mounting groove 33 is provided at the center of the top of the crossbar seat 9. A square locking post 25 is provided at the end of the crossbar seat 9 near the podium 1 and extends into the mounting groove 33. A square pull plate 34 is fixedly connected to one end of the square locking post 25. A tension spring 24 is fixedly connected between the square pull plate 34 and the crossbar seat 9. A mounting post 37 is fixedly connected to the center of the bottom of the display screen 10. The mounting post 37 and the mounting groove 33 are matched in shape. A square slot 36 is provided at one end of the mounting post 37. The square locking post 25 is inserted into the square slot 36 to fix the mounting post 37. When the mounting post 37 is inserted into the mounting groove 33, the mounting post 37 will first contact the inclined surface on the square locking post 25 and move outward. When the mounting post 37 is fully inserted into the mounting groove 33, the elastic action of the tension spring 24 will cause the square locking post 25 to be inserted into the square locking groove 36, thus completing the fixation of the mounting post 37. The upper and lower ends of the square locking post 25 are fixedly connected to the outer side of the crossbar seat 9, and the square strips prevent the square locking post 25 from entering the mounting groove 33 too much.

[0026] Working principle: Before clamping, the display screen 10 bracket is in a separated state, and the limiting post 21 is stored in the telescopic groove 23 and limited by the clamping plate 4. At this time, the arc-shaped hanging plate 2 is hung on the arc-shaped protrusion of the podium 1, and the arc-shaped plate 3 is in contact with the arc surface of the arc-shaped protrusion. The clamping plate 4 is parallel to the bottom of the arc-shaped protrusion. Then, the knob 19 is turned and the threaded rod 18 is rotated. The threaded effect of the threaded rod 18 can make the clamping plate 4 move upward, and the fixing cone 16 is stuck at the bottom of the arc-shaped protrusion until the clamping plate 4 releases the limitation of the limiting post 21. At this time, the elasticity of the spring 22 causes the limiting post 21 to pop out and be stuck at the bottom of the clamping plate 4, thus completing the limitation and fixation of the clamping plate 4. Therefore, the bracket can be quickly installed on the podium 1, improving the installation efficiency and preventing the clamping plate 4 from loosening after long-term use, thereby ensuring the clamping effect. After the bracket is installed on the podium 1, the circular insert 29 is inserted into the circular insertion hole 35 and the mounting post 37 is inserted into the mounting groove 33. The mounting post 37 will first contact the inclined surface on the square locking post 25 and cause the square locking post 25 to move outward. After the mounting post 37 is installed in place, the elasticity of the tension spring 24 causes the square locking post 25 to be inserted into the square locking groove 36, thus completing the fixation of the mounting post 37 and completing the installation and fixation of the display screen 10. Therefore, the bracket and the display screen 10 can be separated during installation to avoid shaking and damage to the display screen 10, thereby improving safety. When in use, the drive motors 12 on both sides can be controlled to operate synchronously by the synchronous controller. The drive motors 12 drive the drive shaft 17 and the winding drum 13 to rotate synchronously. At this time, one winding drum 13 on both sides is in the winding state and the other is in the unwinding state. Therefore, the steel wire ropes 11 on both sides are in the winding and unwinding operation and are in a tensioned state. They carry the support column 8 to move along the arc of the arc frame 6. During the movement, the resistance during the movement can be reduced by the cooperation of the spherical groove 32 and the ball bearing 30, making the movement smoother. The support column 8 carries the display screen 10 to move synchronously and changes the position of the display screen 10, so that students on both sides can see the content on the display screen 10, thereby improving the teaching quality.
