[0027] Example 1

[0028] like Figure 1 As shown;

[0029] A teaching display board comprises a base 1 and a limiting sleeve 2 arranged above the base 1.

[0030] In this implementation scheme: After checking, the public (announcement) number: CN215006972U discloses a multimedia teaching board. Although the design has the advantages of adjustable height and usable area, achieving multi-functionality, in actual teaching use, the audio player and video player of the multimedia teaching board are exposed to the outside for a long time, and the dust generated by the teacher's use of chalk will affect the service life of the machine. When the multimedia teaching board is not used, there is a possibility that students will bump into the video player when playing in their spare time. In order to solve this technical problem, a storage component 3 and a rotating component 4 are added on this basis.

[0031] More specifically:

[0032] like Figures 1 to 6 As shown:

[0033] In combination with the above content: the storage assembly 3 includes a storage box 31, a top plate 32, a first connecting rod 33, a sector gear 34, a first transmission arm 35, a second connecting rod 36, a second transmission arm 37, a third connecting rod 38, a main screen 317, a third transmission arm 39 and a fourth connecting rod 310, the upper surface of the limit sleeve 2 is fixedly connected with the storage box 31, the upper surface of the storage box 31 is fixedly connected with the top plate 32, the first transmission arm 35 is fixedly connected with the first connecting rod 33 at the central position of the end, and the outer surface of the first connecting rod 33 is respectively connected to the inner side of one end of the sector gear 34 and the inner side of one end of the third transmission arm 39. The main panel 317 is fixedly connected to the side, the outer surface of the end of the first connecting rod 33 is rotatably connected to the inner surface of a through hole 315 opened on one side of the top plate 32, the outer surface of the second connecting rod 36 is rotatably connected to the inner side of the other end of the first transmission arm 35 and the inner side of one end of the second transmission arm 37, the upper surface of the main panel 317 is fixedly connected with the third connecting rod 38, the outer surface of the third connecting rod 38 is rotatably connected to the inner side of the other end of the second transmission arm 37, the outer surface of the fourth connecting rod 310 is rotatably connected to the inner side of the other end of the third transmission arm 39, and sub-plates 313 are provided on both sides of the main panel 317, and two fan gears 34 are meshed and connected.

[0034] In this embodiment, when the teacher needs to use the blackboard for teaching, the auxiliary plate 313 is pushed, and the auxiliary plate 313 drives the storage box 31 and the fourth transmission arm 312 to rotate through the fourth connecting rod 310 and the sixth connecting rod 314. Since the third transmission arm 39, the first transmission arm 35, and the fan gear 34 are all fixedly connected to the first connecting rod 33, when the third transmission arm 39 drives the first connecting rod 33 to rotate, the first transmission arm 35 and the fan gear 34 rotate synchronously with the axis of the first connecting rod 33 as the center. The second transmission arm 37 is driven to rotate, and the second transmission arm 37 drives the main screen 317 to move horizontally through the third connecting rod 38. The two fan-shaped gears 34 are meshed and connected, driving the two sub-plates 313 to move synchronously. When the two sub-plates 313 are in contact, they are closed, and the teacher can write on the sub-plates 313. When the teacher needs to use the main screen 317, the sub-plate 313 is pulled outward, and the main screen 317 is driven to move outward to its appropriate position, thereby completing the storage function of the teaching display board, which is conducive to storing the main screen 317 when the sub-plate 313 is in use and when the teaching display board is not in use.

[0035] It should be noted that the top of the storage box 31 is a trapezoidal structure, and its step difference can accommodate the normal movement of the third transmission arm 39 and the fourth transmission arm 312. The first connecting rod 33 is rotatably connected to the top plate 32 and will not fall off, and the stepped structure at the top of the storage box 31 can also act as a fiber. The main screen 317 is a video player with its own audio player.

[0036] Going further:

[0037] In an optional embodiment, the storage assembly 3 also includes a fifth connecting rod 311, a fourth transmission arm 312 and a sixth connecting rod 314. The fifth connecting rod 311 is fixedly connected at the central position of the end of the fourth transmission arm 312. The outer surface of the end of the fifth connecting rod 311 is rotatably connected to the inner surface of the second through hole 316 opened on one side of the top plate 32. The outer surface of the sixth connecting rod 314 is rotatably connected to the inner side of the other end of the fourth transmission arm 312.

[0038] In this embodiment, when the auxiliary plate 313 is pushed, the fourth transmission arm 312 is also driven to rotate. The fourth transmission arm 312 and the third transmission arm 39 are of equal length and are arranged in parallel, thereby ensuring the stability of the auxiliary plate 313 when being pushed.

[0039] It should be noted that the lengths of the third transmission arm 39 and the fourth transmission arm 312 are sufficient to ensure that they will not interfere with the storage box 31 during rotation.

[0040] Going further:

[0041] In an optional embodiment, the rotating assembly 4 includes a connecting plate 41 and a rotating shaft 42, the upper surface of the connecting plate 41 is fixedly connected to the outer side of the bottom end of the fourth connecting rod 310 and the outer side of the bottom end of the sixth connecting rod 314, respectively, the outer surface of the rotating shaft 42 is rotatably connected to the inner surface of the end of the sub-plate 313, and the outer side of one end of the rotating shaft 42 is fixedly connected to the lower surface of the connecting plate 41.

[0042] In this embodiment, when the sub-board 313 needs to be rotated, the sub-board 313 only needs to be rotated around the rotation axis 42 until it is rotated to a suitable angle, so that students from multiple angles can study the content on the sub-board 313.

[0043] Going further:

[0044] In an optional embodiment, the lower surface of the end of the connecting plate 41 is fixedly connected to a limiting plate 44 , and the other end of the rotating shaft 42 is fixedly connected to a limiting ring 43 .

[0045] In this embodiment: the limiting plate 44 can limit the angle of the auxiliary plate 313 to ensure that it can effectively protect the main screen 317 in the closed state, and the limiting ring 43 can ensure that the auxiliary plate 313 will not fall when the outer surface of the rotating shaft 42 rotates.

[0046] Working principle: When the teacher needs to use the blackboard for teaching during the teaching process, the sub-plate 313 is pushed, and the sub-plate 313 drives the storage box 31 and the fourth transmission arm 312 to rotate through the fourth connecting rod 310 and the sixth connecting rod 314. Since the third transmission arm 39, the first transmission arm 35, and the fan gear 34 are all fixedly connected to the first connecting rod 33, when the third transmission arm 39 drives the first connecting rod 33 to rotate, the first transmission arm 35 and the fan gear 34 rotate synchronously with the axis of the first connecting rod 33 as the center. The first transmission arm 35 drives the second transmission arm 37 to rotate through the second connecting rod 36, and the second transmission arm 37 drives the main screen 317 to move horizontally through the third connecting rod 38. The two fan gears 34 are meshed and connected, driving the two sub-plates 313 to move synchronously. When the two sub-plates 313 are in contact, the closure is completed, and the teacher can write on the sub-plate 313. When the auxiliary plate 313 is in a closed position, the main screen 317 is moved outwards to the auxiliary plate 313, and the auxiliary plate 313 is moved outwards to the appropriate position. The storage function of the teaching display board is completed when the auxiliary plate 313 is in use and the main screen 317 is not in use. When the auxiliary plate 313 is pushed, the fourth transmission arm 312 is driven to move at the same time. The fourth transmission arm 312 and the third transmission arm 39 are of equal length and are arranged in parallel, which ensures the stability of the auxiliary plate 313 when it is pushed. When the auxiliary plate 313 needs to be rotated, the auxiliary plate 313 only needs to be rotated around the rotation axis 42 until it is rotated to a suitable angle, so that students from multiple angles can study the content on the auxiliary plate 313. The limiting plate 44 can limit the angle of the auxiliary plate 313 to ensure that it can effectively protect the main screen 317 in the closed state. The limiting ring 43 can ensure that the auxiliary plate 313 will not fall when the outer surface of the rotation axis 42 rotates.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
