Description

Technical Field

[0001] The utility model relates to the technical field of roll-up display stands, in particular to an anti-toppling structure for a roll-up display stand. Background Technique

[0002] A roll-up display stand, also known as a scroll display stand or a roll-up stand, is a common portable display device widely used in exhibitions, conferences, stores, promotional activities and other occasions. It usually consists of a scroll-type display screen with printed images or texts, a support structure (such as an aluminum alloy or plastic bracket), a bottom plate and a portable packing box.

[0003] In the prior art, in the process of using some devices, a folding support mechanism is used to unfold the display stand, so that the roll-up can be fixed on the display stand. However, in this process, the fixed angle of the folded display stand is limited. When the wind direction changes, the roll-up display stand is prone to topple. Therefore, we provide an anti-toppling structure for a roll-up display stand. Summary of the Utility Model

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] Refer to Figures 1 - 3, an embodiment provided by the present utility model: an anti-toppling structure for a roll-up display stand, including a bottom plate 1. The bottom plate 1 is the foundation of the entire roll-up display stand, fixing all subsequent components and mechanisms. A top of the bottom plate 1 is fixedly connected with two fixing plates 2, which play a role in fixing and supporting other components. A first rotating shaft 3 is rotatably connected inside the two fixing plates 2. A limiting plate 4 is fixedly connected to an outer side of one of the fixing plates 2 and is connected to a driving component inside, restricting the rotation range to ensure the stability and support force of the roll-up display stand when it is unfolded. A driving component for providing rotational power is rotatably connected inside the limiting plate 4. The driving component includes a rotating rod 6, and the outer part of the rotating rod 6 is rotatably connected inside the limiting plate 4. A hook rod 8 is detachably connected to the outer part of the rotating rod 6, and a worm 7 is fixedly connected to the outer part of the rotating rod 6. A worm gear 5 is fixedly connected to an outer part of the fixing plate 2. By rotating to drive the worm gear 5 to move, the unfolding and folding of the roll-up display stand are controlled. A worm 7 is fixedly connected to an outer part of the driving component. A rotating shaft 9 is rotatably connected inside the fixing plate 2. A first connecting block 10 is fixedly connected to an outer part of the rotating shaft 9. A telescopic component for providing telescopic length is fixedly connected to an outer part of the first connecting block 10 to ensure the stability and support force of the roll-up display stand, for adjusting the height and length of the roll-up display stand, and increasing its stability and adaptability. The telescopic component includes a first sleeve 11. A strong spring 12 is arranged inside the first sleeve 11. A first sliding rod 13 is slidably connected inside the first sleeve 11. One end of the strong spring 12 is fixedly connected to a bottom of the first sliding rod 13, and the other end of the strong spring 12 is fixedly connected to a bottom inner wall of the first sleeve 11. A second connecting block 14 is fixedly connected to an outer part of the telescopic component. A second rotating shaft 15 is rotatably connected inside the two second connecting blocks 14. A background board 16 is fixedly connected to the outer parts of the second rotating shaft 15 and the first rotating shaft 3.

[0025] Refer to Figure 1 , Figure 4 , a L-shaped fixing rod 17 is fixedly connected to an outer side of the background board 16. A T-shaped sliding block 18 is slidably connected inside the background board 16. When there is no external force, it can block the L-shaped fixing rod 17, so that the roll-up on the L-shaped fixing rod 17 cannot be removed. Two second sleeves 19 are fixedly connected to an outer side of the background board 16. A second sliding rod 20 is slidably connected inside the second sleeves 19. A first spring 21 is sleeved on the outer parts of the second sleeves 19 and the second sliding rod 20. One end of the first spring 21 is fixedly connected to an outer side of the background board 16, and the other end of the first spring 21 is fixedly connected to an outer part of the T-shaped sliding block 18. When pulling the first spring 21, the roll-up inside the L-shaped fixing rod 17 can be taken out.

[0026] Compared with some devices in the prior art, the above content controls the worm 7 on the rotating rod 6 to rotate through the hook rod 8, thereby driving the externally meshed worm wheel 5 to move, and a telescopic structure is rotated on one side of the fixed plate 2, thereby driving the background board 16 to move, so that the roll-up display stand is not prone to toppling.

[0027] Working principle: First, the operator starts the rotating rod 6 by manipulating the hook rod 8. The rotating rod 6 is connected to the worm 7, and then drives the worm wheel 5 to rotate. The rotation of the worm wheel 5 is carried out through the rotating shaft fixed on the fixed plate 2, so that the entire drive system can adjust the angle and position of the display stand to meet different display requirements.

[0028] As the worm wheel 5 rotates, the background board 16 is correspondingly adjusted through the connecting block and the rotating shaft. The movement of the background board 16 is realized by a telescopic assembly, which includes a sleeve and a sliding rod. The built-in strong spring 12 provides the necessary tension to ensure the smooth lifting and lowering of the background board 16 and adjust the height and length of the display stand.

[0029] On one side of the background board 16, the L-shaped fixing rod 17 is used to hang the roll-up display, and the T-shaped sliding block 18 locks or releases the L-shaped fixing rod 17 through the built-in spring mechanism when necessary. When it is necessary to replace or remove the roll-up display, the operator can pull the spring connected to the T-shaped sliding block 18 to make the sliding block retreat, thereby releasing the roll-up display on the L-shaped fixing rod 17.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention 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 perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
