DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0021] like Figure 1-5 As shown, the utility model provides an LED liquid crystal splicing screen that is easy to splice, including a fixing plate 1, a liquid crystal screen 2 is fixedly connected to the rear end of the fixing plate 1, and an adjustment component is provided at the rear end of the fixing plate 1, and the adjustment component is used to adjust the position of the fixing plate 1;

[0022] The adjusting component includes rectangular grooves 16 opened on both sides of the fixed plate 1, and rectangular blocks 17 are slidably connected inside the rectangular grooves 16. The rectangular blocks 17 move inside the rectangular grooves 16. The upper and lower positions of the front ends of the rectangular blocks 17 are fixedly connected to the limit rods 4. The rod walls of the plurality of limit rods 4 are movably connected to the mounting plate 3. The internal threads of the mounting plate 3 are connected to the first threaded rod 5. A sliding groove 6 is opened at the front end of the fixed plate 1. A slider 7 is slidably connected inside the sliding groove 6. The front end of the slider 7 is movably connected to the rear end of the first threaded rod 5. When the first threaded rod 5 rotates, the mounting plate 3 moves back and forth, thereby changing the distance between the fixed plate 1 and the mounting plate 3. A first motor 9 is fixedly connected inside the fixed plate 1. The output end of the first motor 9 is fixedly connected to the second threaded rod 8. The rod wall of the second threaded rod 8 is threadedly connected to the internal thread of the slider 7. The front end of the slider 7 is in the same plane as the front end of the fixed plate 1.

[0023] When splicing the LCD screen 2, first fix the mounting plate 3 on the bracket. At this time, by rotating the first threaded rod 5, the fixing plate 1 and the mounting plate 3 can move back and forth relative to each other, so that the LCD screen 2 and the adjacent LCD screen 2 can be kept in the same plane during installation. Then, the first motor 9 is energized, and the output end of the first motor 9 drives the second threaded rod 8 to rotate. The rotation of the second threaded rod 8 causes the slider 7 to move up and down inside the slide groove 6, so that the fixing plate 1 can move up and down relative to the mounting plate 3, thereby realizing the alignment of adjacent LCD screens 2. The limit rod 4 is set, which can limit the fixing plate 1 to prevent the entire device from shaking. The rectangular groove 16 and the rectangular block 17 are set, so that the fixing plate 1 can be more stable when moving up and down. In this way, when splicing, the position of the LCD screen 2 can be quickly adjusted and aligned through the adjustment component, thereby improving the splicing speed.

[0024] like Figure 1-5 As shown, rectangular openings 14 are provided at the four corners of the mounting plate 3, and a moving block 15 is slidably connected inside the rectangular opening 14. The inside of the moving block 15 is slidably connected to the rod wall of the limiting rod 4, and the moving block 15 is moved inside the rectangular opening 14 to achieve left and right movement of the fixed plate 1 and the mounting plate 3. A through slot 12 is provided at the upper left end of the mounting plate 3, and the upper end of the moving block 15 at the upper left end is fixedly connected to the moving plate 13, and the upper end of the mounting plate 3 is fixedly connected to a supporting block, and the right side of the supporting block is fixedly connected to a second motor 10, and the output end of the second motor 10 is fixedly connected to a third threaded rod 11, and the second motor 10 drives the third threaded rod 11 to rotate, and the rod wall of the third threaded rod 11 is threadedly connected to the inner part of the moving plate 13;

[0025] The second motor 10 is powered on, and the output end of the second motor 10 drives the third threaded rod 11 to rotate, and the third threaded rod 11 drives the movable plate 13 to move inside the through groove 12, and the movable plate 13 drives the movable block 15 to move inside the rectangular opening 14, thereby making the fixed plate 1 and the mounting plate 3 move left and right relative to each other, so that the left and right adjustment of the LCD screen 2 can be achieved during operation, thereby improving the accuracy of the LCD screen 2 during splicing.

[0026] like Figure 3 and Figure 5 As shown, the front end of the slider 7 is fixedly connected to the limit block 18, and the internal movably connected to the limit block 18 is a round block 19, the front end of the round block 19 is rotatably connected to the rear end of the first threaded rod 5, and the front end of the limit block 18 is provided with a circular opening, and the diameter of the circular opening is five times the diameter of the first threaded rod 5. When adjusting, the round block 19 can move in any direction of the limit block 18, and the first threaded rod 5 drives the fixed plate 1 to move forward and backward through the round block 19, thereby improving the applicability of the device.

[0027] Working principle: when splicing the LCD screen 2, first fix the mounting plate 3 on the bracket, and then rotate the first threaded rod 5 so that the fixing plate 1 and the mounting plate 3 can move forward and backward relative to each other, so that when installing, the LCD screen 2 and the adjacent LCD screen 2 can be kept in the same plane, and then the first motor 9 is energized, and the output end of the first motor 9 drives the second threaded rod 8 to rotate. The rotation of the second threaded rod 8 causes the slider 7 to move up and down inside the slide groove 6, so that the fixing plate 1 can move up and down relative to the mounting plate 3, so as to realize the alignment of adjacent LCD screens 2. The set limit rod 4 can limit the fixing plate 1 to prevent the whole device from shaking. The rectangular groove 16 and the rectangular block 17 are arranged so that the fixed plate 1 can be more stable when it moves up and down, so that during splicing, the position of the LCD screen 2 can be quickly adjusted and aligned through the adjustment component, thereby improving the splicing speed. The second motor 10 is powered on, and the output end of the second motor 10 drives the third threaded rod 11 to rotate, and the third threaded rod 11 drives the moving plate 13 to move inside the through groove 12, and the moving plate 13 drives the moving block 15 to move inside the rectangular opening 14, thereby making the fixed plate 1 and the mounting plate 3 move left and right relative to each other, so that the LCD screen 2 can be adjusted left and right during work, thereby improving the accuracy of the LCD screen 2 during splicing.
