Description

Technical Field

[0001] This utility model relates to an advertising display device, and more particularly to a linkage device for a roll-type advertising structure that can be lifted and lowered and has a storage function, which is suitable for storefronts, building exteriors or other occasions where advertising information needs to be displayed vertically. Background Technology

[0002] Traditional advertising billboards are mostly fixed installations, which cannot be raised or lowered to meet display needs, nor do they have storage mechanisms, making them inflexible in use.

[0003] Some lifting billboards using steel cables and pulleys can move vertically, but due to a lack of stable guidance and proper support, the billboards often sway or sag during lifting, affecting the display effect. Furthermore, existing structures are mostly integrally welded or assembled, making construction and maintenance inconvenient and hindering modular modifications. Moreover, when not in use, the billboards remain in an extended state, exposed to wind and rain, making them susceptible to damage or wear. Utility Model Content

[0004] Purpose of the utility model: To address the shortcomings of the prior art, this utility model provides a linkage device for a roll-type advertising structure. The billboard body is composed of canvas and multiple horizontal support bars. With the help of a slide rail and slider structure set on the outside of a fixed frame, the billboard body can be stably raised and lowered along the slide rail. Furthermore, through pulley modules and steel cable mechanisms set at the upper and lower ends, along with a drive shaft and drive unit, the convenience and stability of unfolding and retracting operations are achieved.

[0005] Technical solution: The linkage device of the scroll-type advertising structure consists of the following components:

[0006] A pair of fixed frames positioned opposite each other;

[0007] A billboard body comprising a canvas and multiple horizontal support strips, wherein the canvas connects the multiple horizontal support strips;

[0008] A slide rail structure is provided on the outside of the fixed frame;

[0009] Multiple sliders are respectively disposed at both ends of the transverse support bar, and the multiple sliders are embedded in the slide rail structure;

[0010] Multiple steel cables are installed on the left and right sides of the billboard body, with one end of each steel cable fixed to the bottom horizontal support bar.

[0011] Multiple pulley modules are respectively installed at the upper and lower ends of the fixed frame, and the steel cable is wound around the pulley modules to guide the steel cable;

[0012] A drive shaft is horizontally disposed on the top of the fixed frame, and the drive shaft is connected to the pulley module;

[0013] A drive unit is connected to the drive shaft for driving the drive shaft to rotate.

[0014] Furthermore, the drive unit is a manual rotary handle.

[0015] Furthermore, the drive unit is a detachable electric module with a locking mechanism corresponding to the drive shaft. This locking mechanism allows for quick engagement with the drive shaft, and after operation, it can be removed and stored, preventing damage from prolonged exposure and also providing anti-theft protection.

[0016] Furthermore, the slider is a guide element installed at both ends of the transverse support bar, and the slider moves up and down synchronously with the transverse support bar in the slide rail structure.

[0017] Furthermore, the pulley module is a pair of pulley modules, which are respectively disposed at the upper and lower ends of the fixed frame, and the pair of pulley modules rotate synchronously with the drive shaft.

[0018] Furthermore, the number of steel cables corresponds to the number of pulley modules, and each steel cable is wound around at least one pulley module.

[0019] Furthermore, a vertical reinforcing support rod is provided at the center line of the fixed frame, and the vertical reinforcing support rod passes through the corresponding through hole of the transverse support strip.

[0020] Furthermore, the through hole is located at the centerline of the transverse support bar.

[0021] Furthermore, the transverse support bar and the canvas are interchangeable modular structures.

[0022] Furthermore, the slide rail structure is a slide rail element embedded in a C-shaped steel or aluminum rail.

[0023] When the linkage device of the scroll-type advertising structure is working, the drive unit drives the drive shaft to rotate, which in turn drives the pulley module to raise and lower the steel cable, thereby driving the bottom horizontal support bar to rise and fall along the slide rail structure, and driving the billboard body to unfold or retract.

[0024] This invention uses a drive unit to rotate a drive shaft, which in turn drives a pulley module to rotate, causing the steel cable to extend and retract to control the raising and lowering of the billboard body. When the billboard body is not in use, it is guided by a slider to slide downwards to the bottom of the fixed frame, achieving a three-dimensional stacking storage effect, thus improving its service life and display efficiency.

[0025] In addition, this utility model adds a vertical reinforcing support rod according to the size requirements of the billboard. The support rod has a through hole at the center line position, which allows the reinforcing rod to pass through without affecting the storage stroke, thereby strengthening the vertical rigidity in the unfolded state, preventing the large billboard from being twisted and deformed by the wind, and has the characteristics of modular structure and flexible application.

[0026] Based on the above description, the beneficial effects of this utility model are as follows:

[0027] 1. Stable lifting function: Through the guide structure of slide rail and slider, combined with steel cable and pulley module, the billboard body maintains balance and stability during the lifting process, avoiding shaking and jamming.

[0028] 2. It has a storage and stacking function: when not in display mode, the billboard body slides vertically down and stacks at the bottom of the fixed frame, effectively reducing the space occupied and increasing the flexibility of use.

[0029] 3. Easy to operate and has multiple operating modes: The drive unit is manually operated, and an electric module can be selected for rapid drive. It can be disassembled and stored when not in use to avoid damage and has an anti-theft effect.

[0030] 4. The overall structure is modular, which facilitates maintenance and upkeep.

[0031] 5. The overall structure is equipped with vertical reinforcing support rods according to the actual size, and with through hole design to provide rigid support in the unfolded state, improving the wind resistance and service life of large billboards. Attached Figure Description

[0050] The specific embodiments of this utility model are described in detail below.

[0051] like Figures 1 to 7 As shown, the linkage device of the scroll-type advertising structure consists of the following components: a pair of fixed frames 10, an advertising board body 20, a slide rail structure 30 disposed on the outside of the fixed frames 10, sliders 31 disposed at both ends of the advertising board body 20, multiple steel cables 40, a pulley module 50, a drive shaft 60, and a drive unit 70, wherein:

[0052] like Figure 1 , Figure 2 As shown, the fixed frames 10 are arranged in pairs vertically to support the overall structure.

[0053] like Figure 1 , Figure 2 As shown, the billboard body 20 is composed of a canvas 21 and multiple horizontal support strips 22, as follows: Figure 5 As shown, the canvas 21 is fixed between multiple transverse support bars 22, such that the multiple transverse support bars 22 are spaced apart and can be unfolded or stacked in the vertical direction.

[0054] like Figure 1 , Figure 2 , Figure 6 As shown, each of the horizontal support bars 22 has a slider 31 at both ends. The slider 31 is embedded in the slide rail structure 30. The slide rail structure 30 is fixed to the outside of the fixed frame 10 and extends in the vertical direction, so that the billboard body 20 is guided by the slider 31, thereby enabling the billboard body 20 to move up and down between the fixed frame 10.

[0055] like Figure 1 , Figure 3 As shown, multiple steel cables 40 are respectively arranged on the left and right sides of the billboard body 20 and wound around the pulley module 50. The pulley module 50 is set on the upper and lower sides of the fixed frame 10. One end of each steel cable 40 is fixed to the lowest horizontal support bar 22. The drive unit 70 drives the drive shaft 60 to rotate, which drives the pulley module 50 to raise and lower the steel cables 40, thereby causing the lowest horizontal support bar 22 to rise and fall in the slide rail structure 30. This, in turn, drives the other horizontal support bars 22 and the canvas 21 to unfold or stack, completing the raising and lowering movement of the billboard body 20. The slider 31 is a guide element installed at both ends of each horizontal support bar 22, which slides with the horizontal support bar 22 during the above-mentioned raising and lowering process.

[0056] like Figure 4 As shown, the drive unit 70 is a manual rotary handle, which is connected to the drive shaft 60. In another embodiment, the drive unit 70 is replaced by a detachable electric module, which is also connected to the drive shaft 60. This electric module has a locking structure, allowing it to be removed and stored after operation.

[0057] The above describes the various components of this utility model. Next, we will introduce the usage and advantages of this utility model:

[0058] 1. In use, the operator operates the drive unit 70 to drive the drive shaft 60 to rotate. The drive shaft 60 drives the pulley module 50 to raise and lower the steel cable 40, causing the bottom horizontal support bar 22 to rise and fall within the slide rail structure 30. Through the connection between the canvas 21 and each horizontal support bar 22, the billboard body 20 unfolds into a vertical plane (e.g., ...). Figure 1 (as shown in the diagram) or stacked layer by layer (such as...) Figure 2 (The state shown).

[0059] 2. The slider 31 is embedded in the slide rail structure 30 and slides up and down with the horizontal support bar 22, providing a linear guiding effect, making the billboard display and retraction more stable and smooth, and avoiding shaking and jamming.

[0060] 3. For example Figure 7 As shown, when the billboard body 20 is large, a vertical reinforcing support rod 80 is set in the centerline area of ​​the fixed frame 10, passing through the centerline through hole of each horizontal support bar 22, to increase the structural rigidity in the unfolded state, effectively prevent the canvas 21 from sagging or deforming, and improve the overall wind resistance and stability.

[0061] 4. The pulley module 50 is located at the upper and lower ends of the fixed frame 10 and is coaxially connected with the drive shaft 60, so that the tension of the steel cable 40 is evenly distributed on both sides, ensuring that the overall lifting action is symmetrical and balanced.

[0062] 5. The transverse support bar 22 and the canvas 21 adopt a replaceable modular design and are assembled by screwing, snap-fitting or welding, which facilitates future disassembly, maintenance or replacement.

[0063] 6. The drive unit 70 is interchangeable between manual and electric modules, making it easy to operate and providing anti-theft and waterproof flexibility. The overall device is highly modular and suitable for advertising walls, temporary display stands, or outdoor display applications.

[0064] The embodiments of this utility model have been described in detail above. However, this utility model is not limited to the above embodiments, and various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of this utility model.
