[0002] A drawing display stand is a stand used to display flat items such as drawings, designs, and photos. There are many styles of drawing display stands, including desktop display stands, floor-standing display stands, hanging display stands, etc. Among them, desktop display stands are suitable for use in offices, meetings, etc., floor-standing display stands are suitable for use in exhibition halls, exhibitions, etc., and hanging display stands are suitable for use on walls, foyers, etc.

[0003] When posting drawings on existing drawing display racks, it is usually necessary to open the outer glass frame and glue the drawings to the inner poster board of the display rack with glue. Since the tape and glue have strong viscosity, the drawings are easily damaged and it is inconvenient to replace the drawings. At the same time, the use of glue and tape is also easy to affect the overall appearance of the display rack. For this reason, we propose a display rack that is easy to replace drawings.

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.

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a display stand for convenient replacement of drawings comprises a mounting frame 3, the outer wall of the mounting frame 3 is symmetrically structured and fixedly connected to two support rods 2, a mounting seat 1 is provided at the bottom of the mounting frame 3, the top of the mounting seat 1 is connected and fixed to the two support rods 2, a connecting groove 4 is provided at the bottom of the mounting frame 3, connecting holes 5 are provided on both sides of the inner wall of the connecting groove 4, a rotating seat 6 is rotatably connected to the inner wall of the connecting groove 4, rotating shafts 7 are fixedly connected at both ends of the rotating seat 6, the outer ends of the two rotating shafts 7 are fixedly connected to the first limit blocks 8, and the two rotating shafts 7 are circular. The outer walls are all sleeved with first torsion springs 9, the two rotating shafts 7 pass through the connecting holes 5 respectively and are rotatably connected thereto, a transparent glass 10 is fixedly connected to the top of the rotating seat 6, a first inclined groove 13 is opened on the top of the transparent glass 10, the first inclined groove 13 faces the mounting frame 3, a sponge pad 12 is fixedly connected to the outer wall of the mounting frame 3, a fixing plate 11 is fixedly connected to the outer wall of the sponge pad 12, the transparent glass 10 abuts against the fixing plate 11, one end of the first torsion spring 9 is connected and fixed to the mounting frame 3, and the other end of the first torsion spring 9 is connected and fixed to the first limit block 8.

[0024] The drawing is spread flat on the inner side of the transparent glass 10, and then the transparent glass 10 is rotated in the opposite direction, and the transparent glass 10 and the fixing plate 11 are squeezed to clamp the drawing between the transparent glass 10 and the fixing plate 11. This design can facilitate the replacement of the drawing, making the drawing smoother and more beautiful, and avoids the use of tape or glue for posting, which affects the overall aesthetics of the display stand.

[0025] like Figure 1 and Figure 6 As shown, the top of the mounting frame 3 is fixedly connected to a support frame 14, a mounting groove 15 is provided on the top of the support frame 14, a connecting shaft 16 is rotatably connected to the inner wall of the mounting groove 15, two ends of the connecting shaft 16 respectively penetrate the support frame 14 and extend to its outside, two ends of the connecting shaft 16 are respectively fixedly connected to second limit blocks 17, two ends of the connecting shaft 16 are respectively sleeved with second torsion springs 18, one end of the second torsion spring 18 is connected and fixed to the second limit block 17, and the other end of the second torsion spring 18 is connected and fixed to the side wall of the support frame 14, a mounting plate 19 is fixedly connected to the outer wall of the circumference of the connecting shaft 16, a limiting plate 20 is fixedly connected to the bottom of the mounting plate 19, a second inclined groove 21 is provided on the outer side of the limiting plate 20, and the transparent glass 10 is flipped closed When the transparent glass 10 is closed, the limiting plate 20 is used to limit and fix the transparent glass 10 inward, so that the upper end of the transparent glass 10 can be fixed, thereby improving the stability of the installation of the transparent glass 10. When the transparent glass 10 is turned over, the first inclined groove 13 on the top of the transparent glass 10 will squeeze the second inclined groove 21 on the outer side of the limiting plate 20, so that the limiting plate 20 rotates upward until the transparent glass 10 is located between the limiting plate 20 and the fixing plate 11. The transparent glass 10 is limited and fixed by the limiting plate 20, thereby reducing the interaction force between the transparent glass 10 and the limiting plate 20, so as to facilitate the installation of the transparent glass 10 and reduce the local pressure of the transparent glass 10 to avoid damage to the transparent glass 10.

[0026] Working principle: By flipping the limit plate 20 outward, the limit plate 20 drives the mounting plate 19 to rotate. At this time, the transparent glass 10 drives the rotating shaft 7 to rotate under the action of the first torsion spring 9, so that the transparent glass 10 flips outward, and the drawing is flattened on the inside of the transparent glass 10;

[0027] The transparent glass 10 is rotated in the opposite direction to generate compression between the transparent glass 10 and the fixing plate 11, so that the drawing can be clamped between the transparent glass 10 and the fixing plate 11;

[0028] When the transparent glass 10 flips over, the first inclined groove 13 on its top will squeeze the second inclined groove 21 on the outside of the limiting plate 20, causing the limiting plate 20 to rotate upward until the transparent glass 10 is located between the limiting plate 20 and the fixing plate 11, and the transparent glass 10 is limited and fixed by the limiting plate 20.
