Description

Technical Field

[0001] This utility model relates to the field of poster display stands, specifically a poster fixing stand for exhibitions. Background Technology

[0002] In various poster exhibitions, display stands are an indispensable piece of equipment. They provide a stable display medium for posters, allowing them to be presented to the audience in an orderly and clear manner, thereby enhancing the professionalism and aesthetic appeal of the exhibition. In some exhibition settings, a large number of posters are often needed to convey richer information or display more content. Taking teaching poster exhibitions as an example, large-scale teaching achievement exhibitions may showcase the teaching results of multiple disciplines and classes, with each discipline or class potentially displaying several posters. In academic exchange activities, scholars from different research directions also bring their own research posters, significantly increasing the demand for posters. Currently, the fixed methods commonly used for teaching poster exhibitions have many inconveniences. For example, some exhibitions simply affix posters directly to walls or display boards. This method not only damages the walls or boards but also makes it difficult to change posters once fixed, resulting in extremely poor flexibility. It cannot adapt to teaching scenarios that require frequent updates to poster content, and it is even more difficult to display a large number of posters within a limited space. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide an exhibition poster holder to solve the deficiencies of the prior art.

[0004] The purpose of this utility model is achieved through the following technical solution: an exhibition poster holder, including a support plate and an exhibition panel, wherein multiple mounting strips are fixed to the top of the support plate, the mounting strips are evenly distributed along the circumference of the support plate, the mounting strips are vertically arranged, and an exhibition space is formed between two adjacent mounting strips. An exhibition panel is provided in each exhibition space, and the exhibition panel is detachably connected to the mounting strips. An installation groove is provided on the top of the exhibition panel for placing posters, and the exhibition panel is made of transparent material.

[0005] Furthermore, a groove is provided on the side of the mounting strip near the exhibition panel, the groove extending through the height of the mounting strip, and the side of the exhibition panel is slidably fitted into the groove.

[0006] Furthermore, it also includes a limiting top plate, which is detachably connected to the mounting strip and is used to prevent the exhibition panel from leaving the exhibition space.

[0007] Furthermore, the top of the mounting strip is rotatably provided with a rotating shaft, the axis of the rotating shaft is vertically set, a limiting plate is fixed at the top of the rotating shaft, and a limiting top plate is provided with a limiting groove at the position corresponding to the limiting plate. When the long side of the limiting plate is parallel to the long side of the limiting groove, the limiting plate can pass through the limiting groove, and the length of the limiting plate is greater than the width of the limiting groove.

[0008] Furthermore, the top of the mounting strip has a small-diameter hole and a large-diameter hole sequentially opened from top to bottom. A limiting plate is rotatably installed in the large-diameter hole. The bottom of the rotating shaft passes through the small-diameter hole and is connected to the limiting plate. A rubber ring is fixedly sleeved on the rotating shaft, and the rubber ring is interference-fitted into the small-diameter hole.

[0009] Furthermore, a telescopic shaft is coaxially connected to the bottom of the support plate, and the end of the telescopic shaft away from the support plate is connected to the chassis.

[0010] Furthermore, the telescopic shaft includes a fixed column and a lifting column. The bottom of the fixed column is fixedly connected to the chassis, and the top of the fixed column is provided with a guide groove along its own height direction. One end of the lifting column is slidably adapted to the guide groove, and the other end is connected to the support plate. The cross-section of the guide groove and the cross-section of the lifting column are both rectangular. A lead screw is rotatably installed in the guide groove, and a threaded hole is provided at the bottom of the lifting column. The thread of the lead screw is adapted to the threaded hole.

[0011] Furthermore, a drive shaft is rotatably provided on the side wall of the fixed column. One end of the drive shaft passes through a guide groove and is connected to a first bevel gear. A second bevel gear is fitted on the lead screw. The second bevel gear meshes with the first bevel gear. A handwheel is fixed to the other end of the drive shaft.

[0012] The beneficial effects of this utility model are: 1. By evenly distributing multiple mounting strips along the circumference at the top of the support plate, exhibition spaces are formed between adjacent mounting strips, and exhibition panels are installed, allowing multiple posters to be displayed simultaneously in a limited space. This is especially suitable for scenarios requiring the display of a large number of posters, such as educational poster exhibitions, eliminating the need for additional exhibition racks, effectively saving exhibition space, and making the exhibition more organized.

[0013] 2. The exhibition board uses a detachable connection strip and slides through grooves for easy installation and removal. Posters can be placed directly into the mounting slots at the top of the exhibition board, eliminating the need for clips or tape when changing posters, thus preventing damage and quickly adapting to the frequent poster content updates required in teaching settings.

Detailed Implementation

[0015] Example 1 like Figures 1 to 5 As shown, an exhibition poster holder includes a support plate 1 and an exhibition panel 2. Multiple mounting strips 3 are fixed to the top of the support plate 1, evenly distributed along the circumference of the support plate 1. The mounting strips 3 are vertically arranged, forming an exhibition space between adjacent mounting strips 3. Each exhibition space contains an exhibition panel 2, which is detachably connected to the mounting strips 3. An installation groove 4 is provided on the top of the exhibition panel 2 for placing posters. The exhibition panel 2 is made of transparent material, forming multiple exhibition spaces, allowing for the simultaneous fixing of multiple posters. Posters are placed from the top of the exhibition panel 2 into the installation groove 4. The transparent material of the exhibition panel 2 facilitates viewing the content on the posters. The exhibition panel 2 can be detached from the mounting strips 3. The installation groove 4 of different exhibition panels 2 has different sizes, allowing for the replacement of the appropriate exhibition panel 2 according to the size of the poster, ensuring that the poster does not slide within the exhibition panel 2 and providing better stability.

[0016] Example 2 Based on Embodiment 1, a telescopic shaft is coaxially connected to the bottom of the support plate 1. The end of the telescopic shaft away from the support plate 1 is connected to the base plate 10. The height of the support plate 1 can be adjusted by extending and retracting the telescopic shaft, thereby adjusting the height of the poster display, making it convenient for use in different scenarios.

[0017] Example 3 Based on Example 2, such as Figure 3 and Figure 5As shown, the telescopic shaft includes a fixed column 11 and a lifting column 12. The bottom of the fixed column 11 is fixedly connected to the base 10. The top of the fixed column 11 has a guide groove 13 along its height direction. One end of the lifting column 12 is slidably fitted into the guide groove 13, and the other end is connected to the support plate 1. The cross-section of the guide groove 13 and the cross-section of the lifting column 12 are both rectangular. A lead screw 14 is rotatably installed in the guide groove 12. A threaded hole 15 is opened at the bottom of the lifting column 12, and the lead screw 14 is threaded into the threaded hole 15. A drive shaft 16 is rotatably installed on the side wall of the fixed column 11, and one end of the drive shaft 16 passes through the guide groove 13. The drive shaft 16 is internally connected to a first bevel gear 17, and a second bevel gear 18 is mounted on the lead screw 14. The second bevel gear 18 meshes with the first bevel gear 17. A handwheel 19 is fixed to the other end of the drive shaft 16. Rotating the handwheel 19 drives the drive shaft 16 to rotate. The drive shaft 16 drives the lead screw 14 to rotate through the meshing of the first bevel gear 17 and the second bevel gear 18. Since the cross-section of the guide groove 13 and the cross-section of the lifting column 12 are both rectangular, the rotational freedom of the lifting column 12 is restricted, allowing the lifting column 12 to move linearly along the axial direction of the lead screw 14. By adjusting the height of the support plate 1, the exhibition height can be adjusted.

[0018] Example 4 Based on Example 3, such as Figures 1 to 3 As shown, a groove 5 is provided on the side of the mounting strip 3 near the exhibition panel 2. The groove 5 extends through the height of the mounting strip 3. The side of the exhibition panel 2 slides into the groove 5. It also includes a limiting top plate 6, which is detachably connected to the mounting strip 3. The limiting top plate 6 is used to prevent the exhibition panel 2 from leaving the exhibition space. The exhibition panel 2 slides into the groove 5 from the top of the mounting strip 3, thereby detachably installing the exhibition panel 2 in the exhibition space. After the exhibition panel 2 is installed in place, the limiting top plate 6 is installed on the top of the mounting strip 3 to limit the exhibition panel 2 and prevent the exhibition panel 2 from sliding in the vertical direction.

[0019] Example 5 Based on Example 4, such as Figures 1 to 3As shown, a rotating shaft 7 is rotatably mounted on the top of the mounting strip 3. The axis of the rotating shaft 7 is vertically positioned, and a limiting plate 8 is fixed to the top of the rotating shaft 7. A limiting top plate 6 has a limiting groove 9 at the corresponding position of the limiting plate 8. When the long side of the limiting plate 8 is parallel to the long side of the limiting groove 9, the limiting plate 8 can pass through the limiting groove 9. The length of the limiting plate 8 is greater than the width of the limiting groove 9. The top of the mounting strip 3 has a small-diameter hole and a large-diameter hole sequentially opened from top to bottom. A limiting plate is rotatably mounted in the large-diameter hole. The bottom of the rotating shaft 7 passes through the small-diameter hole and connects to the limiting plate. A device is fixedly sleeved on the rotating shaft 7. A rubber ring is included, which is interference-fitted into a small-diameter hole. The limiting plate 8 is installed with the limiting top plate 6 corresponding to the limiting groove 9, so that the limiting plate 8 can pass smoothly through the limiting groove 9. Thus, the limiting top plate 6 is installed on the top of the mounting strip 3. Then, the limiting plate 8 is rotated so that the limiting plate 8 is perpendicular to the limiting groove 9, that is, the length of the limiting plate 8 corresponds to the width of the limiting groove 9, so that the limiting plate 8 cannot pass through the limiting groove 9. Through the setting of the rubber ring, there is a large friction between the rotating shaft 7 and the mounting strip 3, which can prevent the rotating shaft 7 from deflecting unexpectedly, thus making the installation of the limiting top plate 6 more stable.
