Description

Technical Field

[0001] This utility model relates to the field of display screen bracket technology, specifically a foldable LED display screen bracket. Background Technology

[0002] An LED display screen is a display device that uses light-emitting diodes as its core display unit. By controlling the on / off state, brightness, and color changes of one or more LEDs, it can visualize information such as images, text, and videos. In some temporary application scenarios, such as exhibitions, outdoor events, and temporary advertising, LED displays need to be installed using brackets.

[0003] Since current temporary LED display stands are usually fixed structures that cannot be folded, they take up a lot of space during transportation and subsequent storage, causing inconvenience. Therefore, we propose a foldable LED display stand to solve the above problems. Utility Model Content

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a foldable LED display stand, which solves the problems mentioned in the background section.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution: A foldable LED display stand includes a support plate, on the top of which a mounting bracket assembly and a support foot assembly are fixed. The mounting bracket assembly includes a guide seat fixed to the top of a support plate. The guide seat has two upper limit sliding triangular frames. The front of each triangular frame is fixed with a placement rail for supporting and limiting the LED display screen. The top of the guide seat has two stops for limiting the maximum movement distance of the triangular frames.

[0007] Furthermore, the support foot assembly includes four connecting seats fixed to the top of the support plate. Each connecting seat is rotatably connected to a rotating shaft via a bearing. Each rotating shaft has a folding support foot fixed to its surface. The top of the support plate is equipped with a drive mechanism for driving the four rotating shafts to rotate synchronously.

[0008] Furthermore, the driving mechanism includes a U-shaped plate fixed to the top of the support plate, a drive shaft rotatably connected to the top of the U-shaped plate via bearings, a driving bevel gear fixed to the surface of the drive shaft, worm gears rotatably connected to each connecting seat via bearings, driven bevel gears fixed to the surface of each worm gear, and driven bevel gears meshing with driving bevel gears, worm wheels fixed to the surface of each rotating shaft, and worm wheels meshing with corresponding worm gears, and a motor fixed to the top of the support plate, the output end of the motor being fixedly connected to the bottom end of the drive shaft.

[0009] Furthermore, each of the stops is composed of a positioning block and a strong magnetic block, with the strong magnetic block fixed to one side wall of the positioning block.

[0010] Furthermore, each side wall of the triangular frame is fixed with a crossbar, and the surface of each crossbar is fixed with a protective sleeve.

[0011] Furthermore, two pads are fixed to the bottom of the support plate.

[0012] (III) Beneficial Effects Compared with the prior art, the present invention provides a foldable LED display stand, which has the following advantages: This utility model provides limiting support for the LED display screen through the mounting bracket assembly, while the support foot assembly supports the support plate and the LED display screen mounted on top. After the bracket is no longer in use, both the mounting bracket assembly and the support foot assembly can be folded, thereby reducing the overall size of the LED display screen bracket and solving the pain points of inconvenient transportation, storage and installation of brackets in temporary LED display screen usage scenarios.

[0015] 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.

[0016] Example like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an embodiment of the present invention provides a foldable LED display stand, including a support plate 1, with two pads 4 fixed at the bottom of the support plate 1. When the stand is folded up and placed, the two pads 4 are used as supports to contact the ground, avoiding wear caused by the support plate 1 directly contacting the ground. The top of the support plate 1 is fixed with a mounting bracket assembly 2 and a support foot assembly 3. The mounting bracket assembly 2 includes a guide seat 21 fixed to the top of the support plate 1. The guide seat 21 has two upper sliding triangular frames 22, and four T-shaped limiting slots are provided on the guide seat 21. Each triangular frame 22 has four T-shaped sliding plates that fit the T-shaped limiting slots, thus making the triangular frame 22 more stable during sliding. A crossbar 25 is fixed to one side wall of each triangular frame 22, and a protective sleeve 26 is fixed to the surface of each crossbar 25. When the two triangular frames 22 are folded, one end of each crossbar 25 will fit tightly together, forming a handle. This facilitates hand handling after the bracket is folded as a whole. The protective sleeve 26 is made of rubber, enhancing comfort when the worker's hand comes into contact with the crossbar 25. A placement rail 23 for supporting and limiting the LED display screen is fixed to the front of each triangular frame 22. Figure 3The shaded area represents the LED display screen, which demonstrates its installation. The top of the guide seat 21 is fixed with two blocks 24 for limiting the maximum movement distance of the triangular frame 22. Each block 24 consists of a positioning block 241 and a strong magnetic block 242. The strong magnetic block 242 is fixed to one side wall of the positioning block 241. The blocks 24 can limit the maximum movement distance of the triangular frame 22. When the two triangular frames 22 slide and retract towards the middle, the inner wall of one side of the triangular frame 22 will attract the strong magnetic block 242, thus limiting the folded triangular frame 22 under the action of the strong magnetic block 242. The working principle and usage process of this utility model are as follows: This folding LED display bracket uses a support plate 1 as a basic carrier, a mounting bracket assembly 2 to position and fix the LED display, and a support foot assembly 3 to support the support plate 1 and the LED screen installed on top of it, thus meeting the needs of temporary installation and convenient relocation of the LED display. In use, as shown in the figure, the support foot assembly 3 can first be opened to support the support plate 1. After opening the two triangular frames 22 away from each other, the LED screen can be hung on the two placement rails 23. At this point, the installation of the LED display is complete. Because the LED display is installed by hanging, it is suitable for various applications. For temporary installation and easy relocation, when the two triangular frames 22 are far apart, the two stops 24 can limit their maximum movement distance to prevent them from detaching from the guide seat 21 after excessive movement. After use, the LED display screen can be removed, and then the two triangular frames 22 can be moved to the middle position. After they move, the stops 24 can be used to position them at their reset distance. The strong magnets 242 on the stops 24 can be used to limit and fix the reset triangular frames. Then, after lifting the hand support to a certain height, the support leg assembly 3 can be folded up, and the overall folding of the LED display screen support can be completed.

[0017] like Figure 1 and Figure 3 As shown, in some embodiments, the support foot assembly 3 includes four connecting seats 31 fixed to the top of the support plate 1. Each connecting seat 31 is rotatably connected to a rotating shaft 32 via a bearing. Each rotating shaft 32 has a folding support foot 33 fixed to its surface. The top of the support plate 1 is equipped with a drive mechanism 34 for driving the four rotating shafts 32 to rotate synchronously. In use, the drive mechanism 34 can drive the four rotating shafts 32 to rotate synchronously. When the rotating shaft 32 rotates, it will cause the folding support foot 33 fixed to its surface to open or fold.

[0018] like Figure 4 , Figure 5 and Figure 6As shown, in some embodiments, the drive mechanism 34 includes a U-shaped plate 341 fixed to the top of the support plate 1. The top of the U-shaped plate 341 is rotatably connected to the drive shaft 342 via bearings. A drive bevel gear 343 is fixed to the surface of the drive shaft 342. Two arc-shaped grooves are formed on the top of the U-shaped plate 341, and a rotating ring adapted to the arc-shaped grooves is fixed to the bottom of the drive bevel gear 343, which can further enhance the stability of the drive bevel gear 343 during rotation. The connecting seats 31 are all rotatably connected via bearings. There is a worm gear 344, and each surface of the worm gear 344 is fixed with a driven bevel gear 345. Each driven bevel gear 345 meshes with a driving bevel gear 343. Each surface of the rotating shaft 32 is fixed with a worm wheel 346, which meshes with the corresponding worm gear 344. A motor 347 is fixed to the top of the support plate 1. The motor 347 is a servo motor with a self-locking function, which is driven after being connected to a power source via a wire connector. The output end of the motor 347 is fixedly connected to the bottom end of the drive shaft 342. When in use, the starter motor 347 drives the drive shaft 342 to rotate. The rotation of the drive shaft 342 then drives the fixed driving bevel gear 343 to rotate. When the driving bevel gear 343 rotates, it drives the four driven bevel gears 345 meshing with it to rotate. Since the driven bevel gears 345 are respectively fixed to the surfaces of their corresponding worm gears 344, the rotation of the driving bevel gear 343 drives the four worm gears 344 to rotate synchronously. The rotation of the worm gears 344 then drives the worm wheels 346 to rotate. 6 are fixed on the surface of the rotating shaft 32 respectively. Therefore, when the drive shaft 342 rotates, it can drive the four rotating shafts 32 to rotate synchronously, thereby realizing the extension or folding of the four folding legs 33. The extension or folding of the four folding legs 33 depends on the direction of rotation of the drive shaft 342 driven by the motor 347. Secondly, since the worm gear 344 and worm wheel 346 have a self-locking effect, coupled with the self-locking effect of the motor 347, the four folding legs 33 will be more stable after extension or folding.

[0019] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
