DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Reference Figure 1-Figure 2 The utility model provides an embodiment: a multifunctional teaching management device, including a teaching whiteboard 1, a supporting leg 2 is fixedly connected to the bottom of the teaching whiteboard 1, and the supporting leg 2 is symmetrically distributed in two groups. The two groups of supporting legs 2 provide a stable supporting effect on the teaching whiteboard 1, and a movable component 4 is arranged on the teaching whiteboard 1, and the position of the movable whiteboard 45 can be adjusted by the movable component 4. A limiting component 3 is arranged on the movable component 4, and the angle of the movable whiteboard 45 is adjusted and fixed by the limiting component 3.

[0033] Reference Figure 2 and Figure 3 The movable component 4 includes a movable whiteboard 45. By adjusting the position and angle of the movable whiteboard 45, the effects of sunshade, dustproof and teaching can be achieved. A movable rod 46 is hinged on the right side of the movable whiteboard 45. The movable rod 46 is provided with four groups. The outer periphery of the movable rod 46 is slidably connected with a fixed frame 42. The sliding effect of the movable rod 46 drives the movable whiteboard 45 to move for teaching. A connecting rod 41 is hinged on the right side of the movable rod 46. The moving effect of the connecting rod 41 drives the movable rod 46 to slide. A slider 44 is hinged on the right end of the connecting rod 41. The slider 44 is provided with four groups. A slide groove 43 is opened on the back of the teaching whiteboard 1. The slide groove 43 is provided with four groups. An adjusting component 47 is provided on the outer wall of the slider 44. The position of the slider 44 is adjusted by adjusting the component 47.

[0034] Reference Figure 4 The limiting component 3 includes a circular plate 31, and a card slot 32 is opened on the outer wall of the circular plate 31. There are multiple groups of card slots 32. The card slots 32 are connected with the card blocks 34 at different positions through the multiple groups of card slots 32, so as to limit the movable whiteboard 45 at different angles. The top of the movable rod 46 is fixedly connected with the fixed rod 33, and the inner wall of the fixed rod 33 is elastically connected with the card block 34 through the limiting spring 35. Through the elastic force of the limiting spring 35, the card block 34 always maintains the card connection effect with the card slot 32 when not affected by external force, so as to limit the movable whiteboard 45.

[0035] Reference Figure 3 The adjustment component 47 includes a fixed plate 471, and the fixed plate 471 is provided with two groups. The inner wall of the fixed plate 471 is threadedly connected with a bidirectional threaded rod 472. By rotating the bidirectional threaded rod 472, the two groups of fixed plates 471 are driven to move closer to or away from each other. The right end of the bidirectional threaded rod 472 is rotatably connected with a fixed block 473. A driving motor 474 is fixedly connected to the left side of the back side of the teaching whiteboard 1. By starting the driving motor 474, the bidirectional threaded rod 472 is driven to rotate.

[0036] Reference Figure 3 The outer wall of the fixed frame 42 is fixedly connected to the back of the teaching whiteboard 1, the outer wall of the slider 44 is slidably connected to the inner wall of the slide groove 43, and the sliding effect of the slider 44 drives the connecting rod 41 to move. Two groups of movable whiteboards 45 are provided, and the two groups of movable whiteboards 45 are symmetrically distributed along the center line of the outer wall of the teaching whiteboard 1. By providing two groups of movable whiteboards 45, it is convenient to shield the two sides of the teaching whiteboard 1. The bottom of the circular plate 31 is fixedly connected to the top of the movable whiteboard 45. The fixing effect of the circular plate 31 prevents the circular plate 31 from falling off. The bottom end of the fixed rod 33 is fixedly connected to the top of the movable rod 46. The fixing effect of the fixed rod 33 prevents the fixed rod 33 from falling off.

[0037] Reference Figure 3 The outer wall of the fixed plate 471 is fixedly connected to the outer wall of the slider 44, and the fixing effect of the fixed plate 471 prevents the fixed plate 471 from falling off. The outer wall of the fixed block 473 is fixedly connected to the right side of the back side of the teaching whiteboard 1, and the fixing effect of the fixed block 473 prevents the fixed block 473 from falling off. The output shaft of the driving motor 474 is fixedly connected to the left end of the bidirectional threaded rod 472.

[0038] Reference Figure 4 One end of the limit spring 35 is fixedly connected to the inner wall of the fixing rod 33, and the other end of the limit spring 35 is fixedly connected to the bottom of the block 34. The fixing effect of the limit spring 35 keeps the block 34 fixed to prevent the block 34 from falling off. The outer wall of the block 34 is slidably connected to the inner wall of the fixing rod 33. The sliding effect of the block 34 allows the block 34 to be engaged or unengaged with the slot 32. The outer wall of the block 34 is engaged with the inner wall of the slot 32. The engagement effect of the block 34 and the slot 32 allows the fixing rod 33 to limit the movable whiteboard 45.

[0039] Working principle: When in use, the staff moves the teaching whiteboard 1 to the place where it is needed, and presses the card block 34 to release the card block 34 from the card slot 32, and at the same time releases the limiting effect on the movable whiteboard 45, so that the movable whiteboard 45 rotates to both sides of the teaching whiteboard 1 to keep the movable whiteboard 45 in a horizontal state, and releases the card block 34 so that the card block 34 is engaged with the card slot 32 under the elastic force of the limiting spring 35, and the movable whiteboard 45 is limited to keep the movable whiteboard 45 fixed.

[0040] The staff starts the driving motor 474, so that the driving motor 474 drives the bidirectional threaded rod 472 to rotate. The rotation effect of the bidirectional threaded rod 472 drives the fixed plates 471 to move away from each other, so that the slider 44 slides along the inner wall of the slide groove 43 to the two sides of the teaching whiteboard 1, and the movable rod 46 is driven by the connecting rod 41 to move along the inner wall of the fixed frame 42 toward the back of the teaching whiteboard 1, so that the movable whiteboard 45 is kept at the same horizontal line with the teaching whiteboard 1 for teaching students.

[0041] When the teaching whiteboard 1 produces reflections, or the teaching angle of the movable whiteboard 45 needs to be adjusted, the staff releases the limit of the movable whiteboard 45 and adjusts the angle of the movable whiteboard 45 so that the movable whiteboard 45 has a sunshade effect. When the teaching whiteboard 1 is used up, the staff makes the front of the movable whiteboard 45 correspond to the front of the teaching whiteboard 1, and controls the driving motor 474 to flip, so that the movable rod 46 drives the movable whiteboard 45 to move, so that the front of the movable whiteboard 45 fits with the front of the teaching whiteboard 1, thereby playing a dust-proof role.

[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
