Description

Technical Field

[0001] This utility model relates to the field of backdrop technology, and in particular to a quick-assembly outdoor cultural and artistic event backdrop. Background Technology

[0002] Outdoor backdrops are essential for cultural and artistic events such as art exhibitions, sculpture exhibitions, music festivals, markets, and celebrations. They are used to divide areas, create atmosphere, and display event themes or artwork information. Traditional outdoor backdrop construction typically employs two methods: one is to assemble them using metal trusses and printed fabric, and the other is to assemble and fix them on-site using wooden or metal panels.

[0003] The aforementioned traditional methods have significant drawbacks. First, the setup process is cumbersome and time-consuming, typically requiring multiple people using specialized tools to assemble and secure the equipment in several steps, resulting in low work efficiency and making it difficult to meet the needs of rapid setup and dismantling for outdoor events. Second, the connection between the display panels or printed fabric and the supporting structure lacks reliability. In the variable outdoor environment, especially when affected by wind, relying solely on rope binding, cable ties, or a few screws for connection can easily lead to the display panels loosening, shifting, or even falling off, affecting not only the display effect but also posing safety hazards. Furthermore, existing connection methods are also inconvenient when it is necessary to change or adjust the content of the display panels, failing to achieve rapid assembly and disassembly.

[0004] Therefore, how to provide an outdoor backdrop that is simple in structure, quick to assemble, and ensures a firm and reliable connection between the display board and the support frame has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] The main purpose of this utility model is to provide a quick-assembly outdoor cultural and artistic event backdrop to solve the problems raised in related technologies.

[0006] To achieve the above objectives, according to one aspect of this utility model, a quick-assembly outdoor cultural and artistic activity backdrop is provided, comprising several display sections and several brackets for mounting the display sections. Several base frames are detachably provided below the brackets, which are used to support the brackets on the ground. Several anti-detachment parts are provided on one side of the brackets, and the anti-detachment parts can rotate on the brackets. When the anti-detachment parts are rotated to a horizontal state, the display sections can be mounted on the brackets. When the anti-detachment parts are released, they rotate back to a vertical state, pressing the edges of the display sections onto the brackets.

[0007] Furthermore, the display section includes a display panel with several through holes on its left and right sides, through which the display panel can be mounted on a bracket.

[0008] Furthermore, the bracket includes a bracket frame, and a plurality of second support blocks are fixedly provided at the bottom of the bracket frame, through which the bracket frame can be installed on the base frame.

[0009] Furthermore, a number of limiting rods are fixedly provided on one side of the bracket frame, and the display part can be hung on the bracket frame through the limiting rods.

[0010] Furthermore, the base frame includes a base frame, with a crossbar fixedly provided at the bottom and a plurality of first support blocks fixedly provided at the top.

[0011] Furthermore, the anti-detachment part includes an anti-detachment frame, on which a rotating shaft is rotatably mounted, and the rotating shaft is fixedly connected to the support frame.

[0012] Furthermore, a pressure block is fixedly provided at the end of the anti-detachment frame, and a number of ball bearings are rotatably provided on the side of the pressure block, all of which face the support.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This utility model provides a dual fixing mechanism of "suspension and clamping" by setting a rotatable anti-detachment part and a pressure block on the anti-detachment part, in conjunction with the through hole on the display panel and the limiting rod on the bracket frame. During installation, simply align the through hole of the display panel with the limiting rod and hang it up, then release the horizontal anti-detachment part, allowing it to automatically rotate back to a vertical position under the action of the return torsion spring. The pressure block will then firmly press the edge of the display panel onto the bracket frame. This process requires no additional tools or fasteners, and a single person can complete the installation and locking of a single display panel in seconds, making the operation extremely simple and quick. At the same time, the mechanical clamping action of the anti-detachment part effectively prevents the display panel from accidentally detaching from the limiting rod under the action of external forces such as wind, ensuring the firmness of the connection and the safety of use.

[0015] 2. The backdrop of this utility model is modularly assembled from a standardized base frame, support frame, and display section. The base frame and support frame are securely connected by bolts to the first and second support blocks, and can be easily disassembled. This modular design allows the entire backdrop to be disassembled into compact components when not in use, significantly reducing the space occupied during transportation and storage. Furthermore, users can flexibly increase or decrease the number of support frames and display sections according to the actual site size and display needs, creating backdrops of different lengths and shapes, offering strong adaptability and meeting the diverse exhibition needs of outdoor cultural and artistic activities.

[0026] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0027] This embodiment provides a quickly assembled outdoor cultural and artistic event backdrop, such as... Figure 1 As shown, it includes a base frame 1, a support frame 2, an anti-detachment part 3, and a display part 4.

[0028] The base frame 1 includes a base frame 11. At least two parallel crossbars 12 are fixedly installed at the bottom of the base frame 11. The crossbars 12 are used to place cement blocks, sandbags, or other high-density counterweights after assembly to lower the center of gravity of the entire background panel and enhance its stability against wind and tipping. At the top of the base frame 11, several first support blocks 13 are fixedly installed for connection with the support frame 2.

[0029] The support frame 2 includes a support frame 21. At the bottom of the support frame 21, several second support blocks 22 are fixedly installed. The number and position of the second support blocks 22 correspond one-to-one with the first support blocks 13 on the base frame 1. During assembly, the support frame 21 is placed on the base frame 11, aligning each second support block 22 with the first support block 13 directly below it. Then, bolts are passed through the corresponding holes pre-drilled on the first support blocks 13 and second support blocks 22, and tightened with nuts to secure the support frame 2 firmly to the base frame 1, forming a stable support unit. Multiple such "base frame 1-support 2" units can be arranged side-by-side according to the required length of the background panel.

[0030] On the side of the support frame 21 facing the display surface, several outwardly protruding limiting rods 23 are fixedly installed. These limiting rods 23 are arranged in pairs on the left and right sides of the front side of the support frame 21.

[0031] Display section 4 is the core component for displaying the artwork, mainly comprising display panel 41. Display panel 41 can be made of lightweight yet relatively rigid materials, such as aluminum composite panels, PVC panels, or wooden boards covered with artwork. Several through holes 42 are provided along the left and right edges of display panel 41. The positions and spacing of these through holes 42 correspond one-to-one with the limiting rods 23 on the support frame 21. The diameter of the through holes 42 is slightly larger than the diameter of the limiting rods 23 to facilitate fitting during installation.

[0032] The anti-detachment part 3 is a key mechanism for achieving quick installation and locking, and it is mounted on the bracket frame 21. The anti-detachment part 3 includes an anti-detachment frame 31, which is rotatably connected to the bracket frame 21 via a rotating shaft 34. Specifically, one end of the rotating shaft 34 is fixed to the bracket frame 21, and the anti-detachment frame 31 is sleeved on the rotating shaft 34 and can rotate around it. A return torsion spring (not shown in the figure) is sleeved on the rotating shaft 34. One end of the torsion spring is fixed to the bracket frame 21, and the other end acts on the anti-detachment frame 31. In its natural state, the spring force keeps the anti-detachment frame 31 in a vertical position, such as... Figure 4 As shown.

[0033] At the free end of the anti-detachment bracket 31, i.e., the end away from the pivot 34, a long strip-shaped pressure block 32 is fixedly installed. The plane of the pressure block 32 is parallel to the plane of the support frame 21. In order to reduce frictional resistance when the pressure block 32 rotates to press the display panel 41, multiple ball bearings 33 are rotatably installed on the side surface of the pressure block 32 facing the support frame 21 by means of embedding.

[0034] The installation and use of this backdrop are described in detail below with reference to the accompanying drawings:

[0035] First, construct the basic support structure. Place the required number of base frames 1 on the ground at predetermined intervals. Then, place the brackets 2 one by one onto the corresponding base frames 1, and secure the first support block 13 to the second support block 22 with bolts and nuts to complete the assembly of the support frame. Sufficient counterweights can be placed on the crossbars 12 of the base frames 1 as needed.

[0036] Next, the display panel 41 is installed. Before installation, the operator manually rotates the anti-detachment bracket 31 of the anti-detachment part 3 to a roughly horizontal position, thereby opening up the installation space on the front of the bracket frame 21. During this process, the return torsion spring on the rotating shaft 34 is twisted, storing elastic potential energy. At this time, the display panel 41 is placed close to the bracket frame 21, and the through holes 42 on its left and right sides are aligned and fitted onto the corresponding limiting rods 23, thus suspending the display panel 41 on the bracket frame 21.

[0037] Finally, locking is performed. The operator slowly releases the anti-slip bracket 31, releasing the potential energy stored in the reset torsion spring and driving the anti-slip bracket 31 to automatically rotate back towards the support frame 21. As the anti-slip bracket 31 rotates, the pressure block 32 at its end gradually approaches the surface of the display panel 41. When the anti-slip bracket 31 rotates to the vertical position, the pressure block 32 and its ball bearings 33 precisely press the edge of the display panel 41 tightly against the surface of the support frame 21. The design of the ball bearings 33 ensures that the pressure block 32 makes rolling contact with the surface of the display panel 41 during the pressing process, avoiding possible scratches and making the pressing action smoother. At this point, the display panel 41 is quickly and firmly fixed to the support 2 by the combined effects of the upper hanging of the limiting rod 23 and the through hole 42 and the lateral pressure of the pressure block 32.

[0038] To further enhance the securing effect on the display panel 41, especially for taller display panels 41, anti-detachment parts 3 can be installed at both the top and bottom of the support frame 21. In this case, the distance between the pivots 34 of the two anti-detachment parts 3 should be greater than the height of the display panel 41 to ensure sufficient space for hanging it. The distance between the two vertically positioned pressure blocks 32 should be slightly less than the height of the display panel 41, ensuring that when both anti-detachment parts 3 are reset, the two pressure blocks 32 can simultaneously press the display panel 41 from both sides, achieving a more balanced and reliable locking mechanism.

[0039] When it is necessary to change the display content, simply reverse the operation: rotate the anti-detachment part 3 to a horizontal position to release the pressure, and the display panel 41 can be removed from the limit rod 23. Replace with a new display panel 41, and then release the anti-detachment part 3 again to complete the locking. The entire replacement process is equally quick and easy.

[0040] In order to maintain the aesthetics of the front of the display panel 41, the through hole 42 does not have to penetrate the front of the display panel 41. At the same time, the limiting rod 23 is relatively short. When the display panel 41 is hung on the limiting rod 23, the limiting rod 23 is completely located inside the through hole 42, and the back of the display panel 41 abuts against the bracket frame 21.

[0041] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
