[0030] Embodiment 1

[0031] like Figure 1 and Figure 2 As shown, a suspended rotating display device for educational informationization includes a bracket 1 and a display 2. The upper end of the bracket 1 is fixedly connected to a fixed base 3. The lower end of the bracket 1 is provided with a lifting component 4 fixedly connected to the rear of the outer surface of the display 2. The outer surface of the lifting component 4 is provided with a rotating component 5.

[0032] During the implementation of this embodiment, after the bracket 1 is installed on the wall top through the fixed base 3, the height of the display 2 can be adjusted by the lifting component 4, and the angle of the display 2 can be adjusted by the rotating component 5. The display 2 will eventually display the content to be taught.

[0033] Specifically, in order to achieve height adjustment of the suspended display 2, refer to Figure 3 and Figure 4 In this embodiment, the lifting assembly 4 includes a gear 47, a limiting groove 41 is provided on the middle side of the front inner surface of the bracket 1, a limiting block 42 is slidably connected to the inner surface of the limiting groove 41, a gear ring 43 is fixedly connected to the rear end of the limiting block 42, and the gear 47 is meshed with the gear ring 43. A first circular hole 44 is provided on the rear side of the middle of the left end of the bracket 1 and is connected to the inner surface of the bracket 1. A rotating rod 45 is rotatably connected to the inner surface of the first circular hole 44. The middle part of the outer surface of the rotating rod 45 is fixedly connected to the gear 47, and a servo motor 46 is fixedly connected to the left end of the rotating rod 45. A first round rod 413 is fixedly connected to the lower end of the gear ring 43, and a circular ring cylinder 48 is rotatably connected to the lower part of the outer surface of the first round rod 413. The front front of the outer surface of the circular ring cylinder 48 is fixedly connected to the rear of the outer surface of the display 2.

[0034] For further information, see Figure 3 and Figure 4 In this embodiment, the left end of the servo motor 46 is fixedly connected to a concave plate 412 , and the right end of the concave plate 412 is fixedly connected to the left end of the bracket 1 .

[0035] For further information, see Figure 3 and Figure 4In this embodiment, a circular groove 410 is opened on the right part of the inner surface of the bracket 1, and a round block 411 is rotatably connected to the inner surface of the circular groove 410, and the left end of the round block 411 is fixedly connected to the right end of the rotating rod 45.

[0036] During the implementation process, the servo motor 46 is started so that the output end of the servo motor 46 drives the rotating rod 45 to rotate on the inner wall of the first circular hole 44, thereby driving the gear 47 on the rotating rod 45 to rotate. Since the gear 47 is meshingly connected with the gear ring 43, the rotation of the gear 47 will drive the gear ring 43 to move up and down, and slide on the inner wall of the limiting groove 41 through the limit block 42 to limit the movement position of the gear ring 43, thereby driving the first circular rod 413 at the lower end of the gear ring 43 to move, so that the circular ring tube 48 drives the display 2 to adjust the height.

[0037] The servo motor 46 mentioned above is controlled by a servo control system in the prior art in this solution, which can control the speed, number of revolutions, and rotation angle of the servo motor 46. In this solution, it is only necessary to stop the servo motor 46 in time after completing the number of revolutions and keep the gear 47 stationary until the servo motor 46 is started again.

[0038] For further information, see Figure 3 and Figure 4 In this embodiment, a circular block 49 is fixedly connected to the outer surface of the first round rod 413 and is symmetrically connected to the circular cylinder 48 up and down, and the outer surface diameter of the two circular blocks 49 is larger than the inner surface diameter of the circular cylinder 48.

[0039] As can be seen from the above, when the first round rod 413 moves up and down, the position of the annular tube 48 is limited by the annular block 49 to prevent the annular tube 48 from detaching from the first round rod 413 during the process of pulling up or lowering the first round rod 413, thereby preventing the display 2 from being unable to move up and down.

[0040] Embodiment 2

[0041] On the basis of the first embodiment, this embodiment adds a rotating assembly 5 which can rotatably fix the display 2, so as to achieve the purpose of rotating the suspended display 2.

[0042] Specifically, in order to rotate the suspended display 2, refer to Figure 5In this embodiment, the rotating assembly 5 includes an L-shaped plate 51, a retaining groove ring 53 is fixedly connected to the middle of the outer surface of the annular cylinder 48, a second circular hole 52 is opened in the middle of the lower part of the rear end of the L-shaped plate 51 and is connected to the front end of the L-shaped plate 51, a second round rod 54 is slidably connected to the inner surface of the second circular hole 52, and a retaining block 56 is fixedly connected to the front end of the second round rod 54, and the size and shape of the outer surface of the retaining block 56 are adapted to the size and shape of the inner surface of the retaining groove ring 53. The upper part of the outer surface of the L-shaped plate 51 is fixedly connected to the rear part of the outer surface of the circular ring block 49 located at the upper part.

[0043] For further information, see Figure 5 In this embodiment, an operating block 57 is fixedly connected to the rear end of the second round rod 54, and a plurality of anti-slip strips 58 are fixedly connected to the outer surface of the operating block 57 in an annular distribution.

[0044] During the implementation process, the operating block 57 is pulled so that the operating block 57 drives the second round rod 54 to slide on the inner wall of the first circular hole 44, thereby making the locking block 56 move away from the inner surface of the locking groove ring 53. At this time, the display 2 is rotated so that the display 2 drives the circular ring tube 48 to rotate on the outer surface of the first round rod 413 during the rotation. When the display 2 is rotated to a suitable angle, the second round rod 54 is pushed so that the locking block 56 on the second round rod 54 enters the inner surface of the locking groove ring 53, thereby fixing the angle of the display 2.

[0045] For further information, see Figure 5 In this embodiment, a spring 55 is sleeved on the rear portion of the outer surface of the second round rod 54, and both ends of the spring 55 are fixedly connected to the rear end of the L-shaped plate 51 and the front end of the operating block 57 respectively.

[0046] During the implementation process, when the operating block 57 is pulled, the operating block 57 will drive the spring 55 to be in a stretched state. When the angle of the display 2 is adjusted appropriately and the angle of the display 2 needs to be fixed, the operating block 57 is released, so that the second round rod 54 is reset under the reaction force of the spring 55, and then the locking block 56 can be pushed to lock into the inner surface of the locking groove ring 53, thereby preventing the second round rod 54 from being out of position.

[0047] Working process: when in use, start the servo motor 46, so that the output end of the servo motor 46 drives the rotating rod 45 to rotate, and then drives the gear 47 to rotate. The rotation of the gear 47 drives the gear ring 43 to move up and down, so that the first round rod 413 at the lower end of the gear ring 43 pulls the ring tube 48 to move, and then drives the display 2 to adjust the height, pull the operating block 57, so that the operating block 57 drives the second round rod 54 to slide on the inner wall of the second round hole 52, so that the blocking block 56 is away from the blocking groove ring 53, and pull the spring 55, so that the spring 55 is in a stretched state. When it is adjusted to a suitable angle, release the operating block 57, so that the operating block 57 is reset under the reaction force of the spring 55, and push the blocking block 56 on the second round rod 54 to be stuck in the inner surface of the blocking groove ring 53, so as to fix the angle of the display 2.

[0048] It is easy for those skilled in the art to understand that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
