[0002] In some applications, such as large outdoor advertising screens, multiple LED displays are spliced ​​together to form a huge LED display cabinet.

[0003] refer to Figure 1 During the process of splicing multiple LED displays together, due to various reasons, adjacent LED displays may become misaligned and uneven along one or more directions. For example, two LED displays may be misaligned along their thickness, resulting in a height difference, or misalignment may occur along other directions (such as the horizontal direction), causing steps to appear between adjacent LED displays. Figure 1 When splicing adjacent first and second LED displays together, a step appears at the splicing point, causing misalignment between the two LED displays and uneven surfaces after splicing, requiring adjustment of flatness. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a flatness leveling device for LED display cabinets, which can solve the problem of lifting the target object as pointed out in the background art description.

[0014] The second threaded hole is provided in the longitudinal section and is located at one end of the longitudinal section near the lower transverse section. The second threaded hole penetrates the longitudinal section along the thickness direction of the longitudinal section.

[0015] Furthermore, the transverse portion and the lower transverse portion are both vertically connected to the longitudinal portion, and the longitudinal portion, the upper transverse portion, and the lower transverse portion form a U-shaped open space.

Detailed Implementation

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0028] like Figures 2-6 As shown, this embodiment provides a flatness leveling device for an LED display cabinet, including a first threaded rod 1, a balance pad 3, a bracket 4, a second threaded rod 6, and a balance slider 5. The bracket 4 is provided with a first threaded hole 441 and a second threaded hole 411. The first threaded rod 1 can pass through the first threaded hole 441 and be threadedly connected to the first threaded hole 441, so that the first threaded rod 1 can be screwed in and out relative to the first threaded hole 441, that is, the first threaded rod 1 can rotate relative to the bracket 4. The second threaded rod 6 can pass through the second threaded hole 411 and be threadedly connected to the second threaded hole 411, so that the second threaded rod 6 can be screwed in and out relative to the second threaded hole 411, that is, the second threaded rod 6 can rotate relative to the bracket 4.

[0029] One end of the first threaded rod 1, passing through the first threaded hole 441, can abut against the balance pad 3 to drive the balance pad 3 to move. The first threaded rod 1, the balance pad 3, and the bracket 4 are separate components, that is, the first threaded rod 1, the balance pad 3, and the bracket 4 are independent components. When it is necessary to adjust the flatness, the first threaded rod 1 is threaded into the first threaded hole 441 on the bracket 4, and the balance pad 3 is placed within the area where the end of the first threaded rod 1 passing through the first threaded hole 441 can function. When it is not necessary to adjust the flatness, the first threaded rod 1 can be removed from the first threaded hole 441, and the balance pad 3 can also be moved out of the area where the end of the first threaded rod 1 passing through the first threaded hole 441 can function.

[0030] The end of the second threaded rod 6 that passes through the second threaded hole 411 can abut against the balance slider 5 to drive the balance slider 5 to move. The second threaded rod 6, the balance slider 5, and the bracket 4 are separate components, that is, the second threaded rod 6, the balance slider 5, and the bracket 4 are independent components. When it is necessary to adjust the flatness, the second threaded rod 6 is threaded into the second threaded hole 411 on the bracket 4, and the balance slider 5 is placed within the area where the end of the second threaded rod 6 passing through the second threaded hole 411 can work. When it is not necessary to adjust the flatness, the second threaded rod 6 can be removed from the second threaded hole 411, and the balance slider 5 can also be moved out of the area where the end of the second threaded rod 6 passing through the second threaded hole 411 can work.

[0031] The central axes of the first threaded hole 441 and the second threaded hole 411 are perpendicular to each other. The first threaded rod 1 is screwed in and out along the first direction where the central axis of the first threaded hole 441 is located, and the second threaded rod 6 is screwed in and out along the second direction where the central axis of the second threaded hole 411 is located. The first direction and the second direction are perpendicular to each other, so that the first threaded hole 441 and the second threaded hole 411 can be screwed in and out from two different directions respectively.

[0032] For example, the first threaded rod 1 includes a first rotating handle 11 and a first threaded rod 12. The first rotating handle 11 is fixedly or detachably connected to one end of the first threaded rod 12. The first threaded rod 12 has an external thread along its own axial direction. The external thread on the first threaded rod 12 is adapted to the internal thread provided in the first threaded hole 441, so that the first threaded rod 12 can be threadedly connected to the first threaded hole 441. The external thread is partially or completely provided along the axial direction of the first threaded rod 12, that is, the first threaded rod 12 is partially provided with external threads or the entire first threaded rod 12 is provided with external threads.

[0033] Similarly, the second threaded rod 6 includes a second rotating handle 62 and a second threaded rod 61. The second rotating handle 62 is fixedly or detachably connected to one end of the second threaded rod 61. The second threaded rod 61 has an external thread along its own axial direction. The external thread on the second threaded rod 61 is adapted to the internal thread provided in the second threaded hole 411, so that the second threaded rod 61 can be threadedly connected to the second threaded hole 411. The external thread is partially or completely provided along the axial direction of the second threaded rod 61, that is, the second threaded rod 61 is partially provided with external threads or the entire second threaded rod 61 is provided with external threads.

[0034] For example, the balancing pad 3 is a circular flat plate, which allows the balancing pad 3 to cover as much of the effective area of ​​the target LED display cabinet as possible.

[0035] For example, the balance slider 5 is a strip-shaped block structure, and the balance slider 5 can span across the support 4.

[0036] For example, the flatness leveling device further includes a rotary bearing 2, through which the first threaded rod 1 can pass and rotate relative to the rotary bearing 2. That is, the rotary bearing 2 is detachably mounted on the first threaded rod 1; when needed, the rotary bearing 2 can be mounted on the first threaded rod 1; when not needed, the rotary bearing 2 can be removed from the first threaded rod 1. By cooperating with the rotary bearing 2, the first threaded rod 1 can act on the balance pad 3 over a larger area, enabling more convenient and faster adjustment of flatness over a wider range.

[0037] For example, the bracket 4 includes a longitudinal portion 41, an upper transverse portion 44 and a lower transverse portion 42, the upper transverse portion 44 and the lower transverse portion 42 are respectively connected to the two ends of the longitudinal portion 41, and the longitudinal portion 41, the upper transverse portion 44 and the lower transverse portion 42 form an open space 43 with an opening 423.

[0038] For example, the lateral portion and the lower lateral portion 42 are both vertically connected to the longitudinal portion 41, and the longitudinal portion 41, the upper lateral portion 44 and the lower lateral portion 42 form a U-shaped open space 43.

[0039] For example, the longitudinal portion 41, the upper transverse portion 44, and the lower transverse portion 42 are an integral structure.

[0040] For example, the first threaded hole 441 is provided in the upper transverse portion 44, and the first threaded hole 441 extends through the upper transverse portion 44 along the thickness direction of the upper transverse portion 44.

[0041] For example, the second threaded hole 411 is provided in the longitudinal portion 41 and is located at one end of the longitudinal portion 41 near the lower transverse portion 42. The second threaded hole 411 extends through the longitudinal portion 41 along the thickness direction of the longitudinal portion 41.

[0042] For example, a through hole is also provided in the longitudinal portion 41, and the through hole is arranged along the axial direction of the longitudinal portion 41. A through hole is also provided at one end of the upper transverse portion 44 near the longitudinal portion 41, and the through hole on the upper transverse portion 44 is connected with the through hole on the longitudinal portion 41 to form a through hole with a larger area. By providing through holes, materials can be saved and the overall weight of the bracket 4 can be reduced.

[0043] For example, the lower transverse portion 42 includes a first transverse plate 421 and a second transverse plate 422, which are arranged in parallel and spaced apart. The gap between the first transverse plate 421 and the second transverse plate 422 forms an opening 423, which is strip-shaped.

[0044] For example, the flatness leveling device further includes several fixing components 7, which are spaced apart. Each fixing component 7 includes a fixing screw 71 and a fixing part 72. The fixing plates of each fixing component 7 are arranged parallel to each other at intervals. The fixing part 72 is fixed to the first transverse plate 421 or the second transverse plate 422, and is located at the end of the first transverse plate 421 away from the upper transverse portion 44 or at the end of the second transverse plate 422 away from the upper transverse portion 44. That is, the fixing part 72 is located at the lower end of the lower transverse portion 42, which is also the end of the transverse portion away from the upper transverse portion 44. The fixing part 72 is an integral structure with the first transverse plate 421 or the second transverse plate 422. The fixing part 72 is provided with screw holes, and the fixing screw 71 cooperates with the screw holes, allowing the fixing screw 71 to be threadedly connected to the screw holes.

[0045] refer to Figures 3-6 When it is necessary to adjust the flatness of the LED display cabinet, for example, when the surfaces (upper and / or lower surfaces) of two LED displays spliced ​​together are misaligned and uneven, and flatness adjustment is required, the splicing point of the two LED displays is placed in the open space 43, so that the upper horizontal part 44 and the lower horizontal part 42 are located on the upper and lower surfaces of the LED displays, respectively. Then, the balance pad 3 is placed on the end face of the LED display near the upper horizontal part 44 (i.e., the upper surface). Then, the first threaded rod 12 is passed through the first threaded hole 441 of the upper horizontal part 44. One end of the first threaded rod 12 passing through the first threaded hole 441 passes through the rotary bearing 2 and abuts against the balance pad 3. Then, by rotating the first threaded rod 12, the first threaded rod 12 acts on the balance pad 3, providing a downward force to the balance pad 3. Under the action of the force, the balance pad 3 can push the LED display to move, and finally move the two LED displays to the same horizontal plane, thus achieving flatness adjustment.

[0046] Similarly, when the side surfaces (one or more of the four sides) of two LED displays spliced ​​together are misaligned and uneven, requiring flatness adjustment, the balance slider 5 is aligned with the side surface requiring flatness adjustment. Then, the second threaded rod 6 is passed through the second threaded hole 411, with one end of the second threaded rod 6 abutting against the balance slider 5. By rotating the second threaded rod 6, the balance slider 5 is pushed towards the side surface, thereby pushing the LED display through the balance slider 5, ultimately moving the side surfaces of the two LED displays to the same horizontal plane, achieving flatness adjustment.

[0047] The planarity adjustment can be performed on the surface and side surfaces of two LED displays spliced ​​together simultaneously, or sequentially. For example, the surface of the two LED displays spliced ​​together can be adjusted first, and then the side surfaces of the two LED displays spliced ​​together can be adjusted.

[0048] Similarly, when the interior of the joint between two spliced ​​LED displays is uneven, i.e., when the two side panels of the two LED displays are not aligned, the two side panels are inserted into the opening 423, and then threaded into the screw holes on the fixing part 72 by fixing screws 71. By rotating the fixing screws 71, the fixing screws 71 can act on the side panels from the side, thereby temporarily fixing the two side panels together. Then, by rotating the first threaded rod 1, the first threaded rod 1 acts on the balance shim 3, and the balance shim 3 acts on the two side panels from the vertical direction, finally adjusting the two side panels to the same height, thus achieving flatness adjustment.

[0049] This utility model has a simple structure, is convenient and efficient to operate, and can be applied to the flatness adjustment of different positions of LED displays. When dealing with unevenness problems such as steps encountered during the assembly of large-area LED display cabinets, it can quickly implement corresponding leveling solutions according to their positions, greatly reducing unnecessary waste of manpower, material resources and financial resources during the installation of the screen and saving installation time.

The protection scope of this utility model is not limited to this embodiment, and any other functionally equivalent embodiments fall within the protection scope of this utility model.
