Embodiment 1

[0028] The embodiment of the present invention provides a screen installation leveling tool, please refer to image 3 , image 3 It is a working diagram of the screen installation leveling tool according to Embodiment 1 of the present invention. As shown in the figure, the screen installation leveling tool includes a leveling base plate 20 and at least two hooks 30, and the leveling base plate 20 includes a first surface and a second surface. Two sides, wherein the first side is a plane. At least two second through holes 22 are opened on the leveling substrate 20, and the second through holes 22 are arranged in pairs; the pull hook 30 includes a fixedly connected hook portion 32 and a pulling portion 34; when the screen installation leveling tool is in the In the working state, the leveling substrate 20 is located above the LED box 10 and the first surface is facing the side of the LED box 10, and the hook 32 can pull the LED box 10 to move up and make the top surface of the ...

Embodiment 2

[0032] Please refer to Figure 4-5 , Figure 4 It is a working schematic diagram of the screen installation and leveling tool described in Embodiment 2 of the present invention, Figure 5 It is a schematic diagram of the unhooking operation of the screen installation and leveling tool described in Embodiment 2 of the present invention. The screen installation leveling tool according to Embodiment 2 of the present invention includes a leveling base plate 20 , at least two pull hooks 30 , a first pressing rod 40 and at least two hinged supports 24 . At least two second through holes 22 are opened on the leveling substrate 20 , and the second through holes 22 are arranged in pairs. As a preferred implementation mode, in this embodiment, the number of the second through holes 22 is two.

[0033] The draw hook 30 includes a fixedly connected hook portion 32 and a pull portion 34 , the hook portion 32 can pull the LED box 10 to move up and down, and the pull portion 34 can move up...

Embodiment 3

[0039] Please refer to Figure 6 , Figure 6 It is a schematic diagram of the working structure of the screen installation and leveling tool described in Embodiment 3 of the present invention. As shown in the figure, the embodiment of the present invention provides a screen installation leveling tool, which is different from Embodiment 2 in that it also includes a second pressing rod 50, and the second pressing rod 50 includes at least two second pressing rod bodies 52, the second pressing rod body 52 is fixedly connected with the pulling part 34, by pulling up the second pressing rod body 52, that is, each pair of second pressing rod bodies 52 exerts a force toward the direction of approaching each other, and then passes through the pulling part 34 exerts a force to compress the elastic member 28 , so that the hook portion 32 escapes from the first through hole 18 . The second pressing rod 50 and the first pressing rod 40 cooperate with each other, so that the insertion and...

Abstract

An embodiment of the present invention relates to a screen installation leveling tool, the screen is formed by splicing and fixing at least two LED boxes, the screen installation leveling tool includes a leveling base plate and at least two pull hooks; the leveling base plate includes The first surface, the first surface is a plane, the leveling substrate is provided with at least two second through holes, the pull hook includes a fixedly connected hook portion and a pulling portion, when the screen installation leveling tool is in the In the working state, the leveling substrate is located above two adjacent LED boxes and the first surface is facing one side of the LED boxes, and the pulling part can be moved up and down through the second through hole, The pull hook can pull the LED box to move up and make the top surface of the LED box contact the first surface, so that the positioning pin and the positioning pin hole, the lock buckle and the locking buckle position are fixed to each other. Fine-tuning to eliminate the height difference of the screen caused by accumulated mechanical tolerances.

Description

technical field [0001] The invention relates to the technical field of electronic display equipment production, in particular to a screen installation and leveling tool and a screen installation and leveling method. Background technique [0002] The LED display screen in the prior art is formed by splicing two or more LED display boxes. A single LED box includes a bottom plate and a side wall fixed to the edge of the bottom plate. The inside of the LED box can also be set There are several ribs. In the conventional design, the splicing of LED display screens is to set positioning pins and locks on the outside of the side wall of a single LED box. There are lock buckle positions, and multiple LED cabinets are spliced ​​and fixed through the mutual cooperation of positioning pins and positioning pin holes, lock buckles and lock buckle positions. However, this splicing and fixing method has certain tolerances due to the size and relative position of the positioning pin and th...
