[0002] As is well known, in the field of information display and dissemination, multimedia roll-up banners are widely used in exhibitions, press conferences, and commercial promotions due to their portability and ease of installation. These roll-up banners typically integrate multimedia equipment such as displays and speakers, and compared to traditional paper roll-up banners, they have advantages such as dynamic display and interactive experience.

[0003] Most existing multimedia roll-up banners use fixed support frames in their structural design. While this type of structure can meet basic stability requirements when used on flat ground, the fixed support area makes it difficult to withstand external forces such as pedestrian collisions and natural winds, causing the roll-up banner to tip over. This can not only damage the expensive multimedia equipment inside, but also pose a safety hazard of injuring pedestrians. Utility Model Content

[0024] 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.

[0025] See Figures 1-2 A multimedia roll-up banner includes two sets of mounting brackets 4 and a roll-up banner body 1 disposed inside the two sets of mounting brackets 4. The roll-up banner body 1 is a multimedia roll-up banner. The bottom of the mounting bracket 4 is bolted to a base 6. A connecting block 7 is slidably connected inside the base 6. A support leg 5 is bolted to the bottom of the connecting block 7, and one side of the support leg 5 contacts one side of the base 6. An adjustment component 2 is disposed on one side of the base 6, and one side of the adjustment component 2 is fixedly connected to the bottom of the connecting block 7. A drive component 3 is disposed inside the base 6, and one side of the drive component 3 is engaged with one side of the adjustment component 2.

[0026] First, refer to Figures 1 to 4In this embodiment, the adjusting component 2 includes a horizontal plate 201, a protrusion 208, and a slider 213. The horizontal plate 201 is fixedly connected to the bottom of the connecting block 7 on the side away from the supporting leg 5. Two sets of mounting plates 204 are welded to the side of the horizontal plate 201 near the base 6, and a balance bar 207 is welded between the two sets of mounting plates 204. The slider 213 is slidably connected to the side of the base 6 away from the supporting leg 5, and the slider 213 is engaged with one side of the driving component 3. A push plate 209 is slidably connected inside the slider 213. A second spring 212 is fixedly connected between the push plate 209 and the slider 213. When the push plate 209 moves towards the slider 213, it will compress the second spring 212. When pulley 210 disengages from protrusion 208, second spring 212 will spring push plate 209 back to its initial position. The side of push plate 209 away from slider 213 is slidably connected to the outside of balance bar 207. A central shaft 211 is welded to the bottom of push plate 209. Pulley 210 is rotatably connected to the outside of central shaft 211. Protrusion 208 is located between horizontal plate 201 and base 6. Connecting brackets 206 are welded to both sides of protrusion 208. The side of connecting bracket 206 away from protrusion 208 is welded to one side of base 6. Protrusion 208 is semi-elliptical. Protrusion 208 can be replaced with triangle. Its inclined surface must face pulley 210, and the side with smaller width is closer to pulley 210.

[0027] Specifically, to prevent the pulley 210 from detaching from the central shaft 211, two sets of discs are provided on the outside of the central shaft 211, and the two sets of discs are located on both sides of the pulley 210. The discs can block the pulley 210, preventing the pulley 210 from detaching from the central shaft 211 and causing the device to fail, thus ensuring the normal use of the device.

[0028] Specifically, in order to maintain the balance of the horizontal plate 201, two sets of limiting rods 202 are welded on one side of the base 6. The horizontal plate 201 is slidably connected to the outside of the two sets of limiting rods 202. Thus, on the one hand, the limiting rods 202 maintain the balance of the horizontal plate 201 during movement, preventing the horizontal plate 201 from becoming unbalanced and swaying during movement, and ensuring the normal displacement of the horizontal plate 201. On the other hand, the limiting rods 202 restrict the direction of the horizontal plate 201, preventing the device from failing due to misalignment of the horizontal plate 201, and ensuring the normal use of the device.

[0029] Meanwhile, in order to enable the support leg 5 to be retracted quickly, two sets of first springs 205 are fixedly connected to one side of the horizontal plate 201. The end of the first spring 205 away from the horizontal plate 201 is fixedly connected to one side of the base 6. Thus, when the horizontal plate 201 is pushed, the first spring 205 will be squeezed by the horizontal plate 201. When the horizontal plate 201 is no longer pushed, the first spring 205 will drive the support leg 5 to move back by bouncing the horizontal plate 201, so that the support leg 5 can quickly return to the initial position and complete the retraction.

[0030] Furthermore, in order to prevent the horizontal plate 201 from detaching from the limiting rod 202 during retraction, a buffer pad 203 is provided on the outside of the limiting rod 202. The buffer pad 203 is a rubber buffer pad, and the buffer pad 203 is located on the side of the horizontal plate 201 away from the first spring 205. Thus, the buffer pad 203 can block the horizontal plate 201 and prevent the horizontal plate 201 from detaching from the limiting rod 202.

[0031] When slider 213 is pushed, slider 213 will drive push plate 209 to move. When push plate 209 moves, it will drive pulley 210 to move by driving central shaft 211. After moving, pulley 210 will contact protrusion 208 and be pushed by protrusion 208 to move laterally. At this time, the movement of pulley 210 will drive push plate 209 to move laterally by driving central shaft 211. The movement of push plate 209 will drive horizontal plate 201 to move by pulling balance bar 207. The movement of horizontal plate 201 will drive support leg 5 to move by driving connecting block 7, thereby changing the position of support leg 5 and expanding the support area of ​​the device.

[0032] Finally, see Figure 2 , Figure 5 and Figure 6 In this embodiment, the drive assembly 3 includes a bearing 301, with a threaded tube 304 fixedly connected to the middle of the bearing 301. A sleeve 303 is threaded onto the outer side of the threaded tube 304. The sleeve 303 has a threaded hole inside, and the threads on the inner wall of the threaded hole are compatible with the threads on the outer side of the threaded tube 304. When the threaded tube 304 rotates, it will drive the sleeve 303 to move linearly. The operator can control the direction of movement of the sleeve 303 by controlling the rotation direction of the threaded tube 304. The threaded tube 304 is away from the bearing. One end of 301 is provided with a handle 305, which allows the operator to easily rotate the threaded tube 304. A locking block 302 is provided on the outside of the sleeve 303. The side of the locking block 302 away from the sleeve 303 is locked onto the outside of the slider 213. When the handle 305 is turned to make the threaded tube 304 rotate, the rotation of the threaded tube 304 will cause the sleeve 303 to move linearly. The movement of the sleeve 303 will cause the locking block 302 to move. The movement of the locking block 302 will push the slider 213 to move.

[0033] This multimedia roll-up banner features repositionable support legs 5. When the pulley 210 is pushed by the protrusion 208, the moved support legs 5 expand the support area of ​​the device, forming a stable support surface. This enhances the anti-tipping ability and resists external forces such as collisions and wind, reducing the risk of equipment tipping over and safety hazards, ensuring display stability, and meeting the safe display needs in different scenarios. Furthermore, the support legs 5 can be retracted, making the device easy to transport and store.

[0034] Working principle:

[0035] When using this multimedia roll-up banner, first place it in the desired location. Then, adjust the support area. Specifically, turn handle 305 to rotate the threaded tube 304. The rotation of the threaded tube 304 causes the sleeve 303 to move linearly. The movement of the sleeve 303 causes the locking block 302 to move, which in turn pushes the slider 213. When the slider 213 is pushed, it moves the push plate 209. The push plate 209, during its movement, will... The pulley 210 is displaced by moving the central shaft 211. After moving, the pulley 210 will contact the protrusion 208 and be pushed by the protrusion 208 to move laterally. At this time, the movement of the pulley 210 will drive the push plate 209 to move laterally by driving the central shaft 211. The movement of the push plate 209 will drive the horizontal plate 201 to move by pulling the balance bar 207. The movement of the horizontal plate 201 will drive the support leg 5 to move by driving the connecting block 7, thereby changing the position of the support leg 5, expanding the support area of ​​the device, and improving the anti-overturning ability.
