[0016] This utility model provides an adjustable multimedia display device for international Chinese language teaching, which has the following beneficial effects:

[0017] 1. This adjustable multimedia display device for international Chinese language teaching utilizes an extension plate fixed under a movable plate and an angle-adjusting telescopic rod. Since the extension plate is hinged to the teaching projector via a hinge block, the teaching projector can rotate along the hinge axis. By controlling the extension and retraction of the angle-adjusting telescopic rod, a sliding block can slide within a sliding groove on the teaching projector, and a stop frame can be used to limit its movement. This allows for convenient adjustment of the rotation angle of the teaching projector along the hinge axis, thereby facilitating adjustment of the pitch angle of the multimedia display device and improving its teaching display effect.

[0018] 2. This adjustable multimedia display device for international Chinese language teaching can conveniently adjust the horizontal angle and height of the teaching projector by controlling the power supply of the rotating motor and the height adjustment telescopic rod. While adjusting, the extension rod can slide within the limiting groove opened under the limiting sleeve, and the rotating ring can rotate within the limiting groove, thereby improving the stability of adjusting the teaching projector. This allows for stable and convenient adjustment of the horizontal angle and height of the multimedia display device, further enhancing the teaching display effect of the multimedia display device.

[0034] Please refer to this carefully. Figure 1 , Figure 3 and Figure 4 A position adjustment component 3 is provided above the angle adjustment mechanism 2, and an installation component 4 is provided above the position adjustment component 3. The position adjustment component 3 includes extension rods 306 arranged at equal intervals. The bottom surface of each extension rod 306 is fixedly connected to the upper surface of the moving plate 201. The outer surfaces of several extension rods 306 are fixedly connected to an integral connecting ring 7. The bottom surface of the integral connecting ring 7 is fixedly connected to the upper surface of the moving plate 201. The integral connecting ring 7 is used to install several extension rods 306 together and to improve the connection stability of several extension rods 306.

[0035] Please refer to this carefully. Figure 2 and Figure 3 A rotating ring 307 is fixedly connected to the top of several extension rods 306. A rotating motor 302 is fixedly connected to the upper surface of the moving plate 201. A reinforcing ring 8 is fixedly connected to the output end of the rotating motor 302. The bottom surface of the reinforcing ring 8 is fixedly connected to the upper surface of the moving plate 201. The reinforcing ring 8 is fixed at the connection between the output end of the rotating motor 302 and the moving plate 201, thereby improving the connection stability between the output end of the rotating motor 302 and the moving plate 201.

[0036] Please refer to this carefully. Figure 1 and Figure 2 A height-adjusting telescopic rod 301 is fixedly connected to the upper surface of the rotating motor 302. An installation ring 303 is fixedly connected to the outer surface of the height-adjusting telescopic rod 301. A limiting sleeve 304 is fixedly connected to the bottom surface of the installation ring 303. A limiting groove 305 is opened on the bottom surface of the limiting sleeve 304. Each extension rod 306 is slidably connected to the inside of the limiting groove 305. A rotating ring 307 is rotatably connected to the inside of the limiting groove 305. Since each extension rod 306 slides inside the limiting groove 305 and the rotating ring 307 rotates inside the limiting groove 305, the movement and rotation stability of the moving plate 201 can be improved.

[0037] Please refer to this carefully. Figure 1 and Figure 2 The mounting assembly 4 includes a mounting top plate 401. The upper surface of the height adjustment telescopic rod 301 is fixedly connected to the bottom surface of the mounting top plate 401. The mounting top plate 401 is set on the ceiling to facilitate fixing the mounting top plate 401 in the required position, thereby enabling the multimedia display device to be installed in the required position.

[0038] Please refer to this carefully. Figure 1 and Figure 2The mounting plate 401 has internal threaded connections with mounting bolts 402 arranged in a circular pattern at equal intervals. The top of each mounting bolt 402 passes through the mounting plate 401 and extends to the top of the mounting plate 401. Threaded holes corresponding to the mounting bolts 402 are drilled at the required positions, allowing the mounting bolts 402 to pass through the mounting plate 401 and be threadedly connected to the drilled threaded holes, thereby enabling the multimedia display device to be stably installed in the required position.

[0039] In use, the following steps are taken: First, connect the teaching projector 1, angle adjustment telescopic rod 203, height adjustment telescopic rod 301, and rotating motor 302 to the power supply. When it is necessary to use this multimedia display device to display knowledge of international Chinese teaching, first manually set the mounting plate 401 of the multimedia display device on the ceiling, and drill threaded holes corresponding to the mounting bolts 402 at this position. This allows multiple mounting bolts 402 to pass through the mounting plate 401 and be threadedly connected to the drilled threaded holes, thereby enabling the mounting plate 401 to be firmly fixed in the required position, and thus enabling the multimedia display device to be fixed in the required position.

[0040] Next, by manually controlling the power supply of the height adjustment telescopic rod 301 and the rotating motor 302, the height adjustment telescopic rod 301 can drive the rotating motor 302 to move up and down, thereby facilitating the up and down movement of the teaching projector 1 until the teaching projector 1 reaches a suitable height. While adjusting the height of the teaching projector 1, the extension rod 306 fixed on the moving plate 201 can slide with the rotating ring 307 in the limiting groove 305 opened under the limiting sleeve 304, thereby improving the stability of the up and down movement of the teaching projector 1. The rotating motor 302 drives the moving plate 201 to rotate the teaching projector 1, which can facilitate the adjustment of the horizontal angle of the teaching projector 1. When adjusting the horizontal angle of the teaching projector 1, the extension rod 306 fixed on the moving plate 201 can rotate with the rotating ring 307 in the limiting groove 305 opened under the limiting sleeve 304, thereby improving the rotational stability of the teaching projector 1.

[0041] Then, by controlling the power supply of the angle adjustment telescopic rod 203, the sliding block 204 can be driven to move up and down using the angle adjustment telescopic rod 203. Since the extension plate 202 is fixed under the moving plate 201, the hinge block 205 fixed on the teaching projector 1 can rotate within the extension plate 202. Since the telescopic end of the angle adjustment telescopic rod 203 is hinged to the surface of the sliding block 204, and since the sliding block 204 slides within the sliding groove 206 opened on the teaching projector 1, and the sliding block 204 is blocked by the baffle 207, the pitch angle of the teaching projector 1 can be easily adjusted. After adjusting the projection angle and position of the teaching projector 1, the knowledge of international Chinese teaching can be displayed using the projection of the teaching projector 1.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
