Description

Technical Field

[0001] The utility model relates to the technical field of teaching display equipment, and more specifically, to a teaching display device. Background Art

[0002] Various teaching props are needed in the teaching process, and teaching display equipment is indispensable. It can provide a lot of information in the teaching process and can provide rich and interesting guiding theories. However, the current teaching display devices are relatively fixed and cannot be moved, or are bulky and inconvenient to carry. In particular, art teaching requires a large display board, which cannot display the required content from multiple angles.

[0003] The utility model with announcement number CN219978973U discloses a display device for teaching. The pull rod is pulled open to make the support legs in an open state. After adjusting the length of the support shaft, the third limit bolt is tightened to keep its height unchanged. The first sliding base is pushed forward along the direction of the second support rod to the limit block, so that the folding rod is in an open state. When the display board is opened, the sliding rod is pulled out from the first support rod. The first line limit bolt is tightened to limit the relative sliding of the sliding rod and the first support rod. The sliding rod reaches the limit position along the third slide groove. After the display board is rotated to a suitable angle, the second limit bolt is screwed in to limit the rotation of the display board so that the device remains fixed.

[0004] When the above-mentioned display device is in use, the outer surface of the supporting shaft is rotatably connected to a display board, and the teaching materials are displayed through the display board. However, during teaching, there is not only main knowledge but also auxiliary knowledge. It is inconvenient to display auxiliary knowledge while displaying main knowledge, and the display effect is poor, which affects the teaching effect. Utility Model Content

[0012] Furthermore, a sleeve is fixedly connected to the bottom end of the disc, a long bolt is movably provided on the sleeve, and the long bolt is threadedly connected to the base.

[0013] It can be seen that in the above technical solution, the long bolt is rotated and moved away from the base, thereby releasing the fixation between the disc and the base.

[0014] Furthermore, a top frame is fixedly connected to the top of the first display board, and a limiting assembly is provided on the top frame. The limiting assembly includes a slide plate, two slide rods, two springs, two threaded limiting rods and a plurality of internal threaded sleeves.

[0028] Furthermore, two cross bars 706 are fixedly connected inside the first display board 1 , and the two cross bars 706 are movably sleeved with side plates 705 , and the two sides of the two side plates 705 facing each other are fixedly connected to the two tooth plates 702 .

[0029] Furthermore, a rotating assembly is provided at the bottom of the storage frame 2, and the rotating assembly includes an adjustable telescopic rod 3, a disc 4, a base 5 and a rotating shaft 11. The top end of the adjustable telescopic rod 3 is fixedly connected to the storage frame 2, and the bottom end of the adjustable telescopic rod 3 is fixedly connected to the disc 4, the top end of the rotating shaft 11 is fixedly connected to the disc 4, and the bottom end of the rotating shaft 11 is movably connected to the base 5 through a bearing, and the bottom end of the disc 4 is fixedly connected to a sleeve 10, a long bolt 6 is movably provided on the sleeve 10, and the long bolt 6 is threadedly connected to the base 5.

[0030] The distance between the first display board 1 and the base 5 can be adjusted by the adjustable telescopic rod 3, and the long bolt 6 is rotated and moved away from the base 5 to release the fixation between the disc 4 and the base 5. The disc 4 is rotated to drive the first display board 1 to rotate, and the angle of the first display board 1 is adjusted according to needs.

[0031] Furthermore, the top end of the first display board 1 is fixedly connected to a top frame 8, and a limiting assembly 9 is provided on the top frame 8. The limiting assembly 9 includes a slide plate 901, two slide bars 902, two springs 903, two threaded limiting rods 904 and a plurality of internal threaded sleeves 905. Both ends of the two slide bars 902 are fixedly connected to the top frame 8, both ends of the two springs 903 are respectively fixedly connected to the top frame 8 and the slide plate 901, the top ends of the plurality of internal threaded sleeves 905 are fixedly connected to the slide plate 901, and the top ends of the two threaded limiting rods 904 are respectively threadedly connected to two of the internal threaded sleeves 905.
