[0002] In today's society, public health issues have become a global focus. From the prevention and control of infectious diseases to the advocacy of healthy lifestyles, the timely and effective dissemination of public health knowledge is of immeasurable significance for raising public health awareness and preventing the spread of diseases. As an important carrier for the dissemination of public health knowledge, the performance and design of information display racks directly affect the effectiveness of information transmission.

[0003] Existing promotional material display racks typically use metal or wooden frame structures, assembled through welding, bolting, or other methods, and are categorized as wall-mounted, desktop, and floor-standing types, all of which place promotional materials in slots or trays.

[0004] However, while existing wall-mounted and desktop display racks are relatively lightweight, their functions are limited. These racks can usually only display a single layer or a small amount of promotional materials, failing to create a three-dimensional display effect and having limited information capacity. Furthermore, these racks lack storage design and still occupy fixed space when not in use, which is not conducive to efficient resource utilization. Therefore, a foldable promotional material display rack is proposed to solve the above problems. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1-3This utility model provides an embodiment of a foldable promotional material display rack, including a storage box 1. The storage box 1 is used to store the folded lower display frame 5, upper display frame 6, and fixed display frame 7 for convenient transportation and carrying. The inner wall of the storage box 1 has a groove 2, which is set in a concave T-shape to engage with a slider 3 to maintain its directional sliding. A slider 3 is slidably connected to the inner wall of the groove 2. The slider 3 is set in a T-shaped block to engage with the groove 2 to maintain the stable lateral sliding of the folding frame 4. The top of the slider 3 is fixedly connected to the folding frame 4. The folding frame 4 is set in an S-shape that rotates 90 degrees. The space is used to fold the lower display frame 5 and upper display frame 6. The lower display frame 5 is hinged to the bottom rear side of the folding frame 4. The lower display frame 5 is provided with two opposing sets for unfolding downwards at 180 degrees, contacting and abutting the side wall of the folding frame 4 to unfold at a 90-degree angle. The storage box 1 is in a state where the placement slots on it are vertically upward. The top front of the folding frame 4 is hinged to the upper display frame 6, which has two opposing sets for unfolding upward at 180 degrees, so that the placement slots on it are vertically upward. The front side of the slider 3 is fixedly connected to the fixed display frame 7, which is used to slide out with the folding frame 4, so that the placement slots on it are vertically upward. The top inner wall of the storage box 1 is inserted with a box door 8, which is used to seal the storage box 1 and provide a limit for the folding frame 4 to prevent the folding frame 4 from shaking and hitting inside the storage box 1. The folding frame 4 is slidably connected to the inner wall of the storage box 1. The lower display frame 5 is in contact with the inner wall of the folding frame 4, and the upper display frame 6 is in contact with the inner wall of the folding frame 4. Placement slots are opened at the front of the lower display frame 5, the upper display frame 6, and the fixed display frame 7. The back of the box door 8 is in contact with the front of the fixed display frame 7.

[0032] Reference Figures 4-5 The inner top wall of the folding frame 4 is elastically connected to a limiting block 10 via a limiting spring 9. The limiting block 10 is used to engage with the inner wall of the upper display frame 6, keeping it in an unfolded state. A limiting switch 11 is fixedly connected to the outer wall of the limiting block 10. The limiting switch 11 is set parallel to the outer wall of the folding frame 4, which facilitates manual movement of the limiting block 10 without hindering the folding frame 4 from sliding into the storage box 1. One end of the limiting spring 9 is fixedly connected to the inner wall of the folding frame 4, and the other end of the limiting spring 9 is fixedly connected to the end of the limiting block 10. Through the opposing pressing force between the limiting spring 9 and the folding frame 4, the limiting block 10 is kept engaged with the inner wall of the upper display frame 6 without being affected by external force. The limiting block 10 is slidably connected to the inner wall of the folding frame 4, with its front end inserted into the inner wall of the upper display frame 6. The limiting switch 11 is slidably connected to the inner wall of the folding frame 4.

[0033] Working principle: When the display rack is needed, first open the box door 8 to release the restriction on the folding frame 4. Pull the folding frame 4, and through the directional sliding design of the slider 3 and the slide groove 2, the folding frame 4 can smoothly slide horizontally along the inner wall of the storage box 1. Then, unfold the lower display frame 5 downwards 180 degrees around the hinge point at the bottom rear side of the folding frame 4 until it contacts and abuts against the side wall of the folding frame 4 at a 90-degree angle. At this time, the placement slot on the lower display frame 5 is vertically upward and can be used to place promotional materials. At the same time, unfold the upper display frame 6 upwards around the hinge point at the top front side of the folding frame 4. The upper display frame 6 is rotated 180 degrees so that its placement slot is also vertically upward. During the unfolding process of the upper display frame 6, the limiting spring 9 pushes the limiting block 10 into the inner wall of the upper display frame 6. The opposing squeezing force between the limiting spring 9 and the folding frame 4 makes the limiting block 10 stably engaged, thereby fixing the unfolded state of the upper display frame 6 and preventing it from folding accidentally. The fixed display frame 7 slides out with the folding frame 4, and its placement slot is also vertically upward, so that the three different display frames form a three-dimensional display space, which is convenient for placing different types and sizes of promotional materials, and completing the unfolding and display work of the display rack.

[0034] After the display is finished, manually pull the limit switch 11 to overcome the elasticity of the limit spring 9, causing the limit block 10 to disengage from the inner wall of the upper display frame 6, releasing the limit on the upper display frame 6. Fold the upper display frame 6 downwards by 180 degrees and store it in the gap of the folding frame 4. Then fold the lower display frame 5 upwards by 180 degrees and store it in the gap of the folding frame 4 as well. Finally, push the folding frame 4 so that it slides into the storage box 1 along the slide groove 2 via the slider 3. Close the box door 8 again. The box door 8 is inserted into the top inner wall of the storage box 1, which seals the storage box 1 on the one hand, protecting the internal display frames from dust and moisture, and on the other hand, limits the folding frame 4 to prevent it from shaking and impacting during transportation, ensuring that all parts are intact. At this time, the entire display rack is compact and portable, making it easy to handle and transport.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
