Technical Field

[0001] This utility model relates to the field of publicity and display technology, and in particular to a publicity and display device. Background Technology

[0002] Against the backdrop of rural revitalization, promotional and display devices play a vital role in promoting rural culture, introducing tourism, and advertising agricultural products. However, most rural promotional and display methods remain relatively traditional, relying mainly on fixed display boards and banners, lacking flexibility and interactivity. This makes it difficult to meet the diverse promotional needs of modern rural areas, necessitating an efficient and convenient promotional and display device to enhance the effectiveness of promotion and contribute to the vigorous development of rural culture and industry.

[0003] Existing publicity and display devices mostly adopt simple mechanical structures, such as common fixed display racks, which can only display in one direction. They use basic brackets and display panels, and rely on manually changing the content of the display panels to update the publicity. Some slightly more complex devices have introduced conventional rotating mechanisms, which drive the display panels to rotate by motors or manually. However, these devices often have problems such as complex structure, inconvenient operation, and unsmooth switching of display content, and cannot meet the requirements of rural publicity for display devices.

[0004] However, the inconvenience of switching display content in existing technologies has become a problem restricting the effectiveness of publicity and display. Traditional fixed display boards require frequent manual replacement, which consumes a lot of manpower and time costs. Moreover, in the outdoor rural environment, the replacement of display boards is significantly limited by factors such as weather and site conditions. Furthermore, existing rotating mechanisms often jam due to structural design defects when switching display content, making it impossible to achieve fast and stable content switching. This greatly reduces the timeliness and continuity of publicity and display, making it difficult to meet the actual needs of rural publicity that requires frequent updates of display content to attract the attention of villagers and tourists. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a publicity and display device, which aims to improve upon common fixed display racks that can only display in one direction, require frequent manual replacement, and consume a lot of manpower and time costs, thus failing to meet the requirements of display devices in rural publicity.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a promotional display device, comprising a frame, wherein a flipping component is provided on one side of the outer wall of the frame; The flipping assembly includes a fixed block, the lower surface of which is fixedly connected to one side of the outer wall of the frame. A second rotating shaft is rotatably connected inside the fixed block. A rotating block is rotatably connected to one side of the outer wall of the second rotating shaft. A third rotating shaft is fixedly connected to the inner wall of the rotating block. A connecting rod is rotatably connected to one side of the outer wall of the third rotating shaft. A rotating plate is fixedly connected to one end of the second rotating shaft. The other end of the second rotating shaft is rotatably connected to the lower surface of the inner wall of the frame. A first rotating shaft is rotatably connected to the upper surface of the rotating plate. A first rotating shaft is rotatably connected to the upper surface of the inner wall of the frame.

[0007] Furthermore, a sliding sleeve is fixedly connected to one side of the outer wall of the frame, a limiting shell is fixedly connected inside the sliding sleeve, a spring is fixedly connected to the inner wall of the limiting shell, a connecting column is fixedly connected to one side of the outer wall of the spring, a sliding block is fixedly connected to one side of the outer wall of the connecting column, a limiting block is fixedly connected to one side of the outer wall of the sliding block, and one side of the outer wall of the limiting block is in contact with the locking teeth.

[0008] Furthermore, there are two rotating shafts, both of which are rotatably connected inside the fixed block.

[0009] Furthermore, the fixed block has a groove inside, which fits against the outer wall of the rotating block.

[0010] Furthermore, the limiting shell has a groove inside, which fits against one side of the outer wall of the connecting column.

[0011] Furthermore, the sliding sleeve has a groove inside, and the sliding block is slidably connected to the groove inside the sliding sleeve.

[0012] Furthermore, a support column is slidably connected to the inner wall of the sliding sleeve, and a groove is provided inside the support column, with the locking teeth fixedly connected inside the groove.

[0013] Furthermore, a diagonal rod is fixedly connected to one side of the outer wall of the support column, and a base is fixedly connected to one side of the outer wall of the diagonal rod.

[0014] This utility model has the following beneficial effects: 1. In this utility model, the advertising display device uses a flip component design. First, the connecting rod is pulled to make the rotating block rotate, which causes the second rotating shaft to rotate as well. Since the rotating plate is fixedly connected to the second rotating shaft, the rotating plate rotates stably around the rotating shaft. The cooperation between the fixed block and the first rotating shaft ensures that the rotating plate will not leave the frame range, thereby realizing the rapid switching of the display content, improving the convenience of switching the display content, and meeting the needs of advertising display.

[0015] 2. In this utility model, the device also has a flexible height adjustment function. By pressing the sliding block, the spring is compressed in the groove inside the limiting shell, causing the connecting column to extend and retract within the limiting shell. This causes the sliding block to move the limiting block, and in conjunction with the engagement of the locking teeth, the height adjustment and stable locking are achieved, thus adapting to the display needs of different scenarios. The adjustment mechanism is easy to operate, ensuring the stability of the device at different heights and enhancing the practicality and applicability of the device. Attached Figure Description

[0018] 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.

[0019] Reference Figures 1-5 The present invention provides an embodiment of a promotional display device, comprising a frame 1, which supports and fixes the entire device, provides an installation base for each component, and achieves structural stability. A flipping component is provided on one side of the outer wall of the frame 1. The flipping assembly includes a fixed block 4, the lower surface of which is fixedly connected to one side of the outer wall of the frame 1. A second rotating shaft 7 is rotatably connected inside the fixed block 4. The connection between the fixed block 4 and the second rotating shaft 7 stabilizes the flipping assembly, allowing the device to flip smoothly. One side of the outer wall of the second rotating shaft 7 is rotatably connected inside the fixed block 4. The fixed block 4 provides stable support for the rotating plate 3, ensuring stable rotation of the rotating plate 3. A groove is provided inside the fixed block 4, which fits against the outer wall of the rotating block 8. The second rotating shaft 7 is rotatably connected to one side of its outer wall. A rotating shaft 3 9 is fixedly connected to the inner wall of the rotating block 8. A connecting rod 10 is rotatably connected to one side of the outer wall of the rotating shaft 3 9. A rotating plate 3 is fixedly connected to one end of the rotating shaft 2 7. The other end of the rotating shaft 2 7 is rotatably connected to the lower surface of the inner wall of the frame 1. A rotating shaft 1 6 is rotatably connected to the upper surface of the rotating plate 3. A side of the outer wall of the rotating shaft 1 6 is rotatably connected to the upper surface of the inner wall of the frame 1. The connection between the rotating shaft 1 6 and the rotating plate 3 allows the rotating plate 3 to rotate within the frame 1. At the same time, the fixing of the rotating shaft 1 6 to the frame 1 restricts the range of motion of the rotating plate 3, ensuring that the displayed content will not leave the frame 1 when switching.

[0020] Specifically, the display device uses frame 1 as a supporting foundation to ensure overall structural stability. The cooperation between the fixing block 4 and the rotating shaft 7 in the flipping assembly allows the rotating plate 3 to rotate smoothly. The connection between the connecting rod 10 and the rotating shaft 9 and the rotating block 8 makes operation simple and can effectively transmit force to drive the rotating plate 3 to flip. The setting of the rotating shaft 6 allows the rotating plate 3 to rotate freely within the frame 1, while limiting its range of motion to ensure that the displayed content does not leave the frame 1 when switching.

[0021] Reference Figures 1-5A sliding sleeve 16 is fixedly connected to one side of the outer wall of frame 1. A support column 2 is slidably connected to the inner wall of the sliding sleeve 16. The sliding connection between the support column 2 and the sliding sleeve 16 allows the support column 2 to move up and down within the sliding sleeve 16, realizing the height adjustment function of the device. A diagonal rod 18 is fixedly connected to one side of the outer wall of the support column 2. A base 17 is fixedly connected to one side of the outer wall of the diagonal rod 18. The base 17 provides a stable support foundation for the entire device, ensuring that the device remains stable at different heights. A groove is provided inside the support column 2, and a locking tooth 5 is fixedly connected inside the groove. The locking tooth 5 provides a locking point, allowing for a stable lock after height adjustment. A groove is provided inside the sliding sleeve 16, and a sliding block 11 is slidably connected to the groove inside the sliding sleeve 16. A limit shell 1 is fixedly connected inside the sliding sleeve 16. 5. The limiting shell 15 provides installation space and limiting function for the spring 13 and the connecting column 12, ensuring that they will not detach during adjustment. The spring 13 is fixedly connected to the inner wall of the limiting shell 15. The elastic force of the spring 13 provides power for the reset of the sliding block 11, so that it can automatically return to its original position after the sliding block 11 is released. The limiting shell 15 has a groove inside, which fits against one side of the outer wall of the connecting column 12. The connecting column 12 is fixedly connected to one side of the outer wall of the spring 13. The sliding block 11 is fixedly connected to one side of the outer wall of the connecting column 12. The limiting block 14 is fixedly connected to one side of the outer wall of the sliding block 11. One side of the outer wall of the limiting block 14 fits against the locking tooth 5. The locking design of the limiting block 14 and the locking tooth 5 realizes the locking of the sliding sleeve 16 in a specific position, ensuring that the height remains stable after adjustment.

[0022] Specifically, the promotional display device achieves flexible height adjustment through the sliding connection between the sliding sleeve 16 and the support column 2. The fixed connection between the inclined rod 18 and the base 17 provides a support foundation for the device. The setting of the locking teeth 5 provides a locking point, so that the adjusted height can be stably locked. The sliding block 11 is slidably connected in the groove inside the sliding sleeve 16. With the elastic force of the spring 13 in the limiting shell 15, the sliding block 11 has an automatic reset function. The connecting column 12 effectively transmits the elastic force of the spring 13 to the sliding block 11. The locking design between the limiting block 14 and the locking teeth 5 further ensures the locking stability of the sliding sleeve 16 in a specific position.

[0023] Working principle: For promotional displays, by pulling the connecting rod 10, the connecting rod 10 moves around the rotating shaft 9 as the central axis. At this time, the rotating block 8 rotates, which in turn drives the rotating shaft 7 to move synchronously. At this time, the rotating plate 3, fixed by the rotating shaft 7 and supported by the fixing block 4, can rotate with the rotating block 8. When the rotating plate 3 rotates, the rotating shaft 6 ensures that the rotating plate 3 does not leave the range of the frame 1, thereby realizing the switching of display content.

[0024] Furthermore, when height adjustment is required, the support column 2 remains stable under the support of the diagonal bar 18 and the base 17. At this time, by pressing the sliding block 11, pressure is applied to the connecting column 12. Under the action of the spring 13, the connecting column 12 can extend and retract within the limiting shell 15. The sliding block 11 slides within the sliding sleeve 16, thereby allowing the limiting block 14 to move with the sliding block 11. At this time, the sliding sleeve 16 is moved up and down, so that the sliding block 11 can be engaged in the gap between the teeth 5, achieving the effect of height adjustment.

[0025] 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.
