[0021] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The instrument placement rack involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Example 1

[0023] like Figures 1 to 3As shown, this embodiment proposes a drawing display device for art classrooms, including a main support rod 1. A support frame 2 is welded to the bottom end of the main support rod 1, and a counterweight base 3 is fixed to the bottom end of the support frame 2. A rotating shaft 12 is rotatably inserted into the upper part of the main support rod 1, and an extension rod 8 is fixed to the top of the rotating shaft 12 outside the main support rod 1. The surface of the extension rod 8 is provided with toothed grooves 13. Square grooves are provided on both sides of the top end of the main support rod 1, and movable plates 11 are slidably arranged inside the two sets of square grooves. A spring 10 is fixed to one side of the movable plate 11, and a retaining sleeve 9 is fixed between the two sets of movable plates 11. Two sets of springs 10 are provided, and the two sets of springs 10 are symmetrically distributed inside the two sets of square grooves. The other end of the spring 10 is fixedly connected to the bottom inner wall of the square groove. The width of the square groove is the same as the width of the moving plate 11. The inner wall of the square groove and the outer wall of the moving plate 11 are both smooth and burr-free. The height of the square groove is greater than the height of the sleeve 9. The inner wall of the sleeve 9 is provided with multiple sets of teeth, and the multiple sets of teeth are evenly distributed in a circular array on the inner wall of the sleeve 9. The teeth mesh with the tooth groove 13. The sleeve 9 slides through the top of the main support rod 1 and is sleeved on the outer surface of the extension rod 8. The upper diameter of the rotating shaft 12 is smaller than the inner diameter of the sleeve 9. The sleeve 9 slides on the outer surface of the rotating shaft 12. The lower diameter of the rotating shaft 12 is larger than its upper diameter. The rotating shaft 12 rotates inside the main support rod 1. The surfaces between the two are smooth and tightly attached.

[0024] In this embodiment, the device is first placed in a suitable position. The counterweight base 3 can effectively reduce the risk of the device tipping over. The support frame 2 provides auxiliary support for the device. When it is necessary to adjust the rotation angle of the display panel 4, the two sets of moving plates 11 are first slid down along the square groove at the same time, so that the spring 10 is compressed. The moving plates 11 drive the sleeve 9 to move down until the sleeve 9 is completely separated from the extension rod 8. The sleeve 9 slides along the upper surface of the rotating shaft 12. Then, the display panel 4 is directly rotated to a suitable angle position, that is, the display panel 4 is directly facing the student's vision. At the corner position, the display panel 4 drives the extension rod 8 to rotate, and the extension rod 8 drives the rotating shaft 12 to rotate inside the main support rod 1. Then, the moving plate 11 is released, and under the rebound of the spring 10, the moving plate 11 is pushed to move upward along the square groove. The moving plate 11 drives the sleeve 9 to move upward synchronously. The teeth on the inner wall of the sleeve 9 slide into the toothed groove 13, and the two mesh with each other. Since the sleeve 9 will not rotate under the limitation of the moving plate 11 and the square groove, the extension rod 8 is limited and will not rotate easily, thus finally achieving the limitation and fixation of the angle of the display panel 4.

[0025] Example 2

[0026] like Figure 1 , Figure 4 and Figure 5As shown, based on the same concept as the above embodiment, this embodiment also proposes: a display panel 4 is fixed to the top of the extension rod 8, and multiple sets of magnetic blocks 5 are magnetically attached to the front of the display panel 4; square plates 14 are fixed to both ends of the back of the display panel 4, and slots 15 are opened on the surface of the square plates 14; a locking block 16 is engaged inside the slots 15; a transparent acrylic storage bucket 6 is fixed to one side of the locking block 16; and a dust cover 7 is hinged to the top of the transparent acrylic storage bucket 6. Multiple sets of transparent acrylic storage buckets 6 are magnetically connected to one end of the dust cover 7 at the top. The card blocks 16 are set in an inverted L shape, and there are multiple sets of card blocks 16. Every two sets of card blocks 16 are distributed in a straight array on one side of each set of transparent acrylic storage buckets 6. Multiple sets of card slots 15 are opened. The upper end of the card slot 15 is set as a large rectangular slot, and the height of the large rectangular slot is greater than the height of the card block 16. The lower end of the card slot 15 is set as a small rectangular slot, and the height of the small rectangular slot is equal to the height of the lower end of the card block 16.

[0027] In this embodiment, the teacher can roll up multiple pictures needed for the class in advance and place them into each set of transparent acrylic storage buckets 6 one by one. Note that the pictures should not be pressed or folded forcefully when rolled to prevent dents. Then, the dust cover 7 is flipped over and placed on top of the transparent acrylic storage bucket 6 to reduce dust and other contaminants entering the bucket and soiling the pictures. Next, the clip 16 is aligned with the slot 15. The clip 16 is first inserted into the large rectangular slot at the top of the slot 15, and then the transparent acrylic storage bucket 6 is lowered so that the clip 16 slides down the slot 15 until its lower end slides into the small rectangular slot at the bottom of the slot 15, completing the connection between the transparent acrylic storage bucket 6 and the display panel 4. For installation, the picture to be used can be laid flat on the front of the display panel 4. The four sides of the picture are fixed with magnetic blocks 5. That is, the picture is placed between the magnetic blocks 5 and the display panel 4, and the picture is fixed by the magnetic attraction between the display panel 4 and the magnetic blocks 5. The existing operation method will not be explained in detail here. Instead, first move the transparent acrylic storage bucket 6 upward, so that the card block 16 moves upward along the card slot 15 until the card block 16 slides from the small rectangular slot at the bottom of the card slot 15 to the large rectangular slot at the top of the card slot 15. Then, move the transparent acrylic storage bucket 6 away from the display panel 4 directly, so that the card block 16 slides completely out of the card slot 15, and the transparent acrylic storage bucket 6 can be separated from the display panel 4.

[0028] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
