[0002] Multimedia podium, also known as electronic podium, multimedia electronic podium or central control podium, is a product that integrates podium with computer, multimedia control system, video display stand, audio equipment, audio and video converter and other electronic products. The application scenarios of multimedia podium are very wide, covering education, enterprise, government, conference and other fields.

[0003] Among them, multimedia teaching has been gradually applied by various colleges and universities with the continuous development of science and technology. In the teaching process, traditional teaching and multimedia teaching are usually combined for teaching. In particular, English, as a language subject, is inseparable from culture. Language is a special social and cultural phenomenon, which is a convention formed by people in long-term social life practice. In the traditional teaching method, teachers can only give oral explanations, and this abstract language expression is not conducive to students' understanding. With the development of multimedia, this problem has been solved. Some abstract expressions have been transformed into intuitive images, videos, etc. through the application of multimedia courseware, which is no longer difficult for students to understand.

[0047] When in use, the drawer 13 is pulled outward so that the drawer 13 is pulled out from the drawer opening 2. During the process of the drawer 13 being pulled, the slide bar 11 moves accordingly, so that the moving rod 16 also moves accordingly. The moving rod 16 pulls the first connecting rod 17, and the first connecting rod 14 pulls the flap 5 to rotate around the rotating shaft 6 until the moving rod 16 is in contact with the fixed rod 9. At this time, the flap 5 is in a vertical state and the display 8 is exposed. When not in use, the drawer 13 is pushed in the opposite direction, and the moving rod 16 is driven by the slide bar 11 to move away from the fixed rod 9. Through the linkage of the first connecting rod 17, the flap 5 is closed, and the display 8 is put into the upper cabinet 1, thereby protecting the display 8.

[0048] In one embodiment of the present invention, a first slide groove 18 is provided inside the fixing rod 9, a slot 19 communicating with the first slide groove 18 is provided in the middle of the fixing rod 9, and a second slide groove 20 communicating with the first slide groove 18 is provided on the lower surface of both ends of the fixing rod 9. A symmetrically arranged card block 21 is slidably connected in the first slide groove 18, a first compression spring 22 is provided between the end of the first slide groove 18 and the card block 21, and a first pin shaft 23 is fixedly connected to the lower end of the card block 21. The first pin shaft 23 extends downward through the second slide groove 20, and a support is fixedly connected to one side of the fixing rod 9 close to the drawer 13.

[0049] An inserting block 31 for inserting into the slot 19 is fixedly connected to one side of the moving rod 16 close to the fixing rod 9 .

[0050] When the moving rod 16 approaches the fixed rod 9, the insert block 31 is first inserted into the slot 19. The insert block 31 squeezes the two card blocks 21 during the insertion process, so that the two card blocks 21 have forces in opposite directions, so that the two card blocks 21 move in opposite directions. When the moving rod 16 fits the fixed rod 9, under the elastic force of the first compression spring 22, the card block 2 and the insert block 31 are clamped and locked. At this time, the moving rod 16 and the fixed rod 9 cannot be separated, so that the flap 5 opened in a vertical state can be locked. When the flap 5 needs to be closed, at this time, the pull rod 30 is pulled outward, and the pull rod 30 drives the connecting rod 29 away from the fixed rod 9. The connecting rod 29 drives the second connecting rod 28 to pull the swing rod 26 to rotate around the second pin 25. The swing rod 26 drives the card block 21 away from the insert block 31, and the first compression spring 22 shrinks in the hand. At this time, the drawer opening 2 can be pushed to make the moving rod 16 away from the fixed rod 9, and the flap 5 rotates to close.

[0051] In one embodiment of the present invention, a handle 32 is fixedly connected to one side of the drawer 13 away from the fixing rod 9. The setting of the handle 32 facilitates the user to push and pull the drawer 13, that is, when the display 8, keyboard 14 and mouse 15 need to be used, the drawer 13 is pulled out from the drawer opening 2.

[0052] In one embodiment of the present invention, grooves 33 are provided on the upper surfaces of both ends of the support plate 7, and a first baffle 34 is arranged in the groove 33. The upper end of the first baffle 34 is fixedly connected to a rubber pad 35, and the lower end of the first baffle 34 is fixedly connected to a support rod 36. The support rod 36 extends downward through the support plate 7 so that the support rod 36 is slidably connected to the support plate 7. A second baffle 37 is fixedly connected to the support rod 36 below the support plate 7, and a bracket 38 is arranged below the second baffle 37. The support rod 36 passes through the bracket 38 so that the support rod 36 is slidably connected to the bracket 38. The bracket 38 is fixedly connected to the top of the upper cabinet 1, and a second compression spring 39 is sleeved on the support rod 36 between the bracket 38 and the second baffle 37. In a natural state, the elastic force of the second compression spring 39 pushes the second baffle 37 upward, so that the second baffle 37 contacts the lower surface of the support plate 7. At this time, the first baffle 34 and the rubber pad 35 are pushed out of the groove 33. When the computer is not needed, the flap 5 needs to be closed. The flap 5 contacts the rubber pad 35 at the moment of closing, thereby playing a buffering role.

[0053] In one embodiment of the present invention, a through hole 40 is provided in the middle of the support plate 7, and a locking ring 41 is provided at the through hole 40. The locking ring 41 is fixedly connected to the lower end of the flap 5, and a locking hook 42 is clamped on the locking ring 41, and a connecting shaft 43 is fixedly connected to the locking hook 42. The connecting shaft 43 passes through the side wall of the upper cabinet 1 so that the connecting shaft 43 is rotatably connected to the side wall, and a knob 44 is fixedly connected to the outer end of the connecting shaft 43. A third baffle 45 is fixedly connected to the connecting shaft 43, and a torsion spring 46 is sleeved on the connecting shaft 43 between the side wall of the upper cabinet 1 and the third baffle 45, and the two ends of the torsion spring 46 are respectively fixedly connected to the side wall of the upper cabinet 1 and the third baffle 45. In a natural state, the torsion of the torsion spring 46 causes the locking hook 42 to be inserted into the locking ring 41, so that the flap 5 is locked and cannot be lifted and opened. When the knob 44 is turned counterclockwise, the locking hook 42 is separated from the locking ring 41, and the flap 5 can be lifted to use the computer.

[0054] In one embodiment of the present invention, the circumference of the knob 44 is fixedly connected to the limiting block 47, and a semicircular ring limiting groove 48 is provided on the side wall of the upper cabinet 1. The semicircular ring limiting groove 48 is located on the circumference of the knob 44, and the limiting block 47 is inserted into the semicircular ring limiting groove 48. Under the elastic force of the torsion spring 46, in the natural state, the limiting block 47 is located on the right side of the semicircular ring limiting groove 48. At this time, the lock ring 41 and the lock hook 42 are in a locked state. When the locked state needs to be contacted, the knob 44 only needs to be rotated counterclockwise, and the limiting block 47 moves to the left along the semicircular ring limiting groove 48 to unlock.

[0055] In one embodiment of the present invention, the insert block 31 includes a rectangular block 49 fixedly connected to the moving rod 16, and the other end of the rectangular block 49 is fixedly connected to a triangular block 50, and the ends of the two clamping blocks 21 close to each other are provided with an inclined surface 51 that fits with the triangular block 50. When the insert block 31 is inserted into the slot 19, the triangular block 50 fits with the inclined surface 51 first, and as the insert block 31 is continuously inserted, the triangular block 50 squeezes the two clamping blocks 21, so that the two clamping blocks 21 have forces in opposite directions, so that the two clamping blocks 21 move in opposite directions. Since the width of the triangular block 50 is greater than the width of the rectangular block 49, when the two clamping blocks 21 are located between the triangular block 50 and the moving rod 16, the clamping block 21 presses against the rectangular block 49 under the pressure of the first compression spring 22, and locks the insert block 31.

[0056] In one embodiment of the present invention, a through hole 52 is provided on one side of the drawer 13 near the fixing rod 9. The through hole 52 in the present application is used for the connection lines on the keyboard 14 and the mouse 15 to pass through.
