DETAILED DESCRIPTION

[0021] In order to enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally also includes steps or units that are not listed, or optionally also includes other steps or units inherent to these processes, methods, products or devices.

[0022] References to "embodiments" herein mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0023] like Figure 1-8 As shown, a multimedia teaching podium includes a podium body 1 and a foldable display screen 2. A receiving groove 4 is provided on one side of the top surface of the podium body 1. A base 11 is provided at the top rear end of the podium body 1. A movable mechanism 5 is mounted within the base 11. A vertically reversible fixed plate 6 is mounted on the movable mechanism 5. The display screen 2 is mounted on the fixed plate 6 via a telescopic connecting rod 8. The ends of the telescopic connecting rod 8 are hinged to the display screen 2 and the fixed plate 6, respectively. The display screen 2 can be folded and flipped to be received in the receiving groove 4. In this embodiment, the telescopic connecting rod 8 includes a fixed sleeve 81 and a telescopic rod 82. One end of the telescopic rod 82 is movably connected to the fixed sleeve 81. The fixed sleeve 81 is provided with a fastener 83.

[0024] The moving mechanism 5 includes a screw rod 51, a moving seat 52, and a motor. The base 11 is located on the inner side of one end of the receiving groove 4 and has a mounting groove extending laterally therefrom. The screw rod 51 is arranged in the mounting groove and its two ends are rotatably connected to the two ends of the mounting groove. The motor is arranged in the base 11. The output shaft of the motor is connected to the screw rod 51 through a shaft coupling. The moving seat 52 is screwed onto the screw rod 51. The side wall of the mounting groove is provided with a slide rail that is slidably connected to the moving seat 52. The front side of the moving seat 52 is provided with a connecting plate 521 extending from the mounting groove. The lower end of the fixed plate 6 is provided with a connecting seat 63. The connecting plate 521 is provided with a connecting shaft. The connecting seat 63 is rotatably connected to the connecting shaft. The outer end of the connecting shaft is threadedly connected to a tightening handwheel 522. Specifically, the connecting seat 63 is rotatably sleeved on the outside of the connecting shaft through an axial hole. When the folded display screen 2 needs to be flipped, the tightening handwheel 522 is loosened to rotate the fixed plate 6 through the connecting seat 63, thereby flipping the display screen 2.

[0025] A control switch 7 for controlling the motor is provided on the top surface of the base 11 , so that personnel can conveniently control the moving position of the display screen 2 .

[0026] The dimensions of the fixing plate 6 match those of the receiving slot 4. A retaining plate 61 is located on the top of the fixing plate 6. The top of the podium body 1 features a retaining slot 41 that engages with the retaining plate 61. A pull ring 62 is located on the back of the retaining plate 61. When the fixing plate 6 is tilted downward, it covers the receiving slot 4, effectively protecting the display screen 2. The retaining plate 61 engages with the retaining slot 41, providing support. The pull ring 62 facilitates the pulling motion to flip the display screen.

[0027] The front end of the podium body 1 is provided with a retractable keyboard tray 3 for convenient placement and storage of the keyboard.

[0028] During use, the hand wheel 522 is loosened and tightened, and the fixed plate 6 is pulled upward by the pull ring 62 to flip the display screen 2. The angle of the display screen 2 can be adjusted appropriately according to the use requirements. The hand wheel 522 is then tightened to fix the angle of the display screen 2. The motor is started by the control switch 7. The screw rod 51 rotates, and the display screen 2 is moved to the appropriate position. The control switch 7 is then turned off, and the display screen 2 is unfolded. At this time, the telescopic connecting rod 8 is in a retracted state. After use, the display screen 2 is folded. At this time, the telescopic connecting rod 8 is in an extended state. The display screen 2 is then controlled to move to the initial position by the control switch 7. After loosening and tightening the hand wheel 522, the fixed plate 6 is flipped downward so that the folded display screen 2 is stored in the receiving slot 4. The display screen 2 of the present invention can be folded and stored, takes up little space, and is easy to achieve space miniaturization.

[0029] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
