Description

Technical Field

[0001] This utility model relates to the technical field of teaching demonstration, and in particular to a multimedia teaching demonstration device. Background Technology

[0002] Multimedia teaching refers to the process in which teachers, based on teaching objectives and the specific characteristics of the students, meticulously design lessons, rationally select and utilize modern teaching media, and combine them with specific teaching demonstration devices, integrating them into the entire teaching process. By leveraging diverse media information to influence students and constructing a logical teaching workflow framework, the teaching effectiveness is optimized.

[0003] However, current digital multimedia teaching display devices have certain shortcomings. Traditional display devices typically rely on magnets to hold paper teaching materials or pictures. But they are ineffective when displaying physical objects. In such cases, the objects must be placed on the lectern, making them difficult for students in the back rows to see. The teacher then has to pick up the objects one by one to display them, a cumbersome process that is both time-consuming and energy-draining. Therefore, we have developed a new type of multimedia teaching display device to solve these problems. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0019] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0020] The multimedia teaching and display device of this utility model embodiment will now be described with reference to the accompanying drawings.

[0021] like Figures 1-3 As shown, the multimedia teaching display device of this utility model embodiment may include two rocker mechanisms 10, a telescopic mechanism 20, and a display board 30.

[0022] Two rocker mechanisms 10 are located near one end of the lectern 40 and are symmetrically arranged on both sides of the lectern 40, and the two rocker mechanisms 10 are pivotally connected to the lectern 40 respectively.

[0023] One end of the telescopic mechanism 20 is pivotally connected to the podium 40, and the other end of the telescopic mechanism 20 is pivotally connected to one of the rocker mechanisms 10.

[0024] It should be noted that the telescopic mechanism 20 described in this embodiment can be a cylinder, a hydraulic cylinder, or an electric telescopic rod. The initial state of the output end of the telescopic mechanism 20 is the retracted state, while... Figure 1 The output end of the telescopic mechanism 20 shown is in the extended state.

[0025] The display panel 30 is mounted on two rocker mechanisms 10, and one end of the bottom wall of the display panel 30 is pivotally connected to one of the rocker mechanisms 10.

[0026] In this embodiment of the utility model, the podium 40 is provided with symmetrical openings 41 for the rocker mechanism 10 to swing.

[0027] Specifically, when the teacher does not need to use the display board 30 to display physical objects, the teacher can control the output end of the retractable mechanism 20 to retract and drive the two rocker mechanisms 10 to swing. The swinging two rocker mechanisms 10 drive the display board 30 to rotate to one side of the podium 40 and place it there, thereby avoiding the upright display board 30 from obstructing the teacher's view.

[0028] When the teacher needs to use the display board 30 to display the object, the teacher can control the output end of the telescopic mechanism 20 to extend and drive the two rocker mechanisms 10 to rotate the display board 30 from one side of the podium 40 to above the podium 40. By placing the object on the display board 30, which is higher than the podium 30, the teacher can display the object so that students in the back row (i.e., those far from the podium 40) can observe the object.

[0029] When a teacher needs to use the display board 30 to display paper teaching materials or patterns, the teacher can stand the display board 30, which is horizontally set on the two rocker mechanisms 10, upright (e.g., Figure 3 As shown in the diagram, the paper teaching materials or patterns to be displayed are attached to the display board 30 using a magnet. This not only displays paper materials or patterns but also effectively supports the display of physical objects, thus significantly improving teaching efficiency and effectiveness.

[0030] To clearly illustrate the previous embodiment, in one embodiment of this utility model, as follows: Figure 1 and Figure 2 As shown, the rocker mechanism 10 may include a drive rod 11, a driven rod 12, and a support plate 13.

[0031] One end of the drive rod 11 is pivotally connected to the side wall of the podium 40, the other end of the drive rod 11 is pivotally connected to the support plate 13, and the middle part of the drive rod 11 is pivotally connected to the output end of the telescopic mechanism 20.

[0032] Driven rod 12 and driven rod 11 are arranged side by side. One end of driven rod 12 is pivotally connected to the side wall of lectern 40, and the other end of driven rod 12 is pivotally connected to support plate 13. In one of the rocker mechanisms 10, support plate 13 is connected to the bottom wall of display panel 30 at one end via hinge 50.

[0033] Understandably, when a teacher needs to display an object using the display board 30, the teacher can control the output end of the extendable mechanism 20 to extend and push the drive rod 11 to cause the support plate 13 and the driven rod 12 to swing and rotate synchronously. At this time, the display board 30 located on one side of the podium 40 rotates from a vertical state to a horizontal state and rotates above the podium 40 (e.g., Figure 1 (As shown).

[0034] Then, the teacher can place the physical objects on a display board 30, which is 40 cm higher than the podium, for display. This allows students in the back rows to also see the displayed objects, eliminating the need for the teacher to pick up and display each object individually, thus reducing the teacher's workload and saving time.

[0035] Furthermore, in one embodiment of this utility model, such as Figure 3 As shown, a first magnet block 31 is fixed on the bottom wall of the other end of the display panel 30. The display panel 30 is attracted and connected to the corresponding support plate 13 through the first magnet block 31. The support plate 13 is an iron plate.

[0036] Understandably, by fixing the first magnet block 31 to the bottom wall of the other end of the display panel 30, the first magnet block 31 can be attracted to the support plate 13 when the display panel 30 is in a horizontal state, thereby increasing the stability of the display panel 30 when it is in a horizontal state. This also allows the display panel 30 to stably support the object.

[0037] Furthermore, in one embodiment of this utility model, such as Figure 3 As shown, the multimedia teaching display device may also include a support column 60 and a support rod 70.

[0038] The support column 60 is fixedly installed between two support plates 13, and multiple equidistant parallel adjustment slots 61 are provided on the support column 60. A mounting slot 32 is provided on the bottom wall of the display plate 30, and a support rod 70 is installed in the mounting slot 32. One end of the support rod 70 near the hinge 50 is pivotally connected to the end of the mounting slot 32 via a pivot. A second magnet 71 is provided on the side wall of the other end of the support rod 70, and the other end of the support rod 70 is attracted to the display plate 30 via the second magnet 71. The display plate 30 is made of iron.

[0039] It is understandable that by setting a second magnet 71 at the other end of the support rod 70, the support rod 70 can be fixed in the mounting groove 32 by being attracted by the second magnet 71.

[0040] Specifically, when it is necessary to stand up the horizontal display board 30 to display paper teaching materials or patterns, the teacher can pull up the display board 30 and attach it to one end of the support plate 13 through the first magnet block 31, and rotate the display board 30 to nearly 90 degrees to stand it up.

[0041] Then, the teacher unscrews the other end of the support rod 70 from the mounting slot 32 and places it against the corresponding adjustment slot 61, thus supporting the display board 30. The teacher can then use a magnet to attach paper teaching materials to the display board 30 for display.

[0042] In summary, the multimedia teaching display device of this utility model embodiment can not only display paper materials or patterns, but also effectively support and display physical objects, thereby significantly improving teaching efficiency and effectiveness.
