[0002] At present, in order to meet users' needs for larger screen viewing, multiple LED display unit boards are assembled into a whole LED display assembly. However, when multiple LED display unit boards are simply assembled, a gap will be generated between two adjacent LED display unit boards, resulting in a small part of the image being missing, affecting people's viewing. Therefore, in order to ensure that there are as few gaps as possible between the unit boards, multiple LED display unit boards are generally installed in a mounting substrate or mounting frame, and the unit boards are tightly fitted to each other to eliminate the gaps.

[0003] However, in common splicing structures, LED display screens are generally installed and connected by welding or bolting, and the installation process is relatively cumbersome.

Detailed implementation manners

[0024] The present utility model will be further described below in conjunction with the accompanying drawings and implementation manners.

[0025] Please refer to Figure 1-Figure 8。The splicing structure of the LED display screen includes: a load-bearing wall panel 1 and four LED display unit panels 14. The four LED display unit panels 14 are distributed in a matrix and are attached to each other. And on the side of the load-bearing wall panel 1 away from the LED display unit panels 14, a U-shaped connecting frame 2 is fixedly installed. A vertical bidirectional lead screw 3 is rotatably installed therein. At the top of the U-shaped connecting frame 2, a first servo motor is fixedly installed, and its output shaft is fixedly connected to the top end of the vertical bidirectional lead screw 3. Two L-shaped linkage plates 4 are threadedly installed on the vertical bidirectional lead screw 3. And in order to ensure the stable linear lifting of the linkage plates 4, a stabilizing rod is fixedly installed in the U-shaped connecting frame 2. The stabilizing rod passes through the two linkage plates 4 and is slidably connected to the two linkage plates 4. And two sliding grooves are opened on the load-bearing wall panel 1. The two linkage plates 4 respectively pass through the two sliding grooves, so as to form a sliding relationship with the load-bearing wall panel 1. Above each of the two linkage plates 4, there are two mounting seats 11. A retention slot 12 is opened on each of the four mounting seats 11. An L-shaped insertion plate 13 is inserted into each of the four retention slots 12. And on one side of the four insertion plates 13, they are respectively fixedly connected to the four LED display unit panels 14. A limiting groove 15 is opened on one side of each of the four insertion plates 13 close to the load-bearing wall panel 1. An activity hole 16 is opened on one side of each of the four mounting seats 11 close to the load-bearing wall panel 1. The activity hole 16 communicates with the retention slot 12. And above each of the two linkage plates 4, there are two support plates 8. On the side of each of the four support plates 8 away from the load-bearing wall panel 1, a positioning column 17 is fixedly installed. The four positioning columns 17 respectively pass through the four activity holes 16, and the end parts of the four positioning columns 17 respectively extend into the four limiting grooves 15. In this way, the insertion of the positioning column 17 into the limiting groove 15 can be used to form a clamping effect on the insertion plate 13, so that it cannot be easily pulled out of the retention slot 12 during the use state, ensuring the stability during use. The positioning column 17 and the limiting groove 15 are in a matching relationship, and they will not loosen when inserted. An electric push rod 9 is fixedly installed on each of the four support plates 8. The output shafts of the four electric push rods 9 respectively pass through the four support plates 8 and are movably connected to the corresponding support plates 8. And a connecting block 10 is fixedly installed at the bottom of each of the four mounting seats 11. The output shafts of the four electric push rods 9 are respectively fixedly connected to the four connecting blocks 10. The telescopic movement of the output shaft of the electric push rod 9 is used to control the insertion or extraction of the positioning column 17 into or out of the limiting groove 15, which is convenient for disassembly and assembly.

[0026] In the above method, in order to be able to adjust the installation position according to the actual size of the LED display unit board 14 to improve the applicability, a concave frame 5 is fixedly installed on the top of the two linkage plates 4, and a transverse bidirectional screw 6 is rotatably installed in the two concave frames 5. Two sliding seats 7 are threadedly installed on the two transverse bidirectional screws 6, and the bottoms of the four support plates 8 are respectively fixedly connected to the four sliding seats 7. In addition, a second servo motor is fixedly installed on the outer wall of one side of the two concave frames 5, and the output shafts of the two second servo motors are respectively fixedly connected to one end of the two transverse bidirectional screws 6, and two sliding rods are fixedly installed in the two concave frames 5. The two sliding rods pass through the corresponding sliding seats 7 and are slidably connected to the corresponding sliding seats 7.

[0027] The working principle of the splicing structure of the LED display screen provided by the utility model is as follows:

[0028] When the LED display unit board 14 needs to be removed for inspection or replacement, the output shaft of the corresponding electric push rod 9 is first started to extend, and its output shaft drives the corresponding connection block 10 to move linearly, so that the corresponding mounting seat 11 and the LED display unit board 14 can be moved horizontally together. After being pushed to the final position, the corresponding positioning column 17 is separated from the limiting groove 15, and the corresponding plug board 13 loses the position of the positioning column 17. Then, the LED display unit board 14 can be directly pulled out together with the plug board 13, and then it can be inspected or replaced;

[0029] When reinstalling the repaired or new LED display unit board 14, the plug board 13 on the LED display unit board 14 is directly inserted into the retaining slot 12, and then the output shaft of the electric push rod 9 is started to retract, and the corresponding positioning column 17 is automatically inserted into the limiting slot 15 on the plug board 13, thereby completing the removal and replacement of the LED display unit board 14;

[0030] After the first servo motor is started, the two linkage plates 4 begin to approach each other, and the first servo motor is turned off after the two vertical LED display unit boards 14 are in contact with each other, and the first servo motor is turned off after the two vertical LED display unit boards 14 are in contact with each other, and the first servo motor is turned off after the two linkage plates 4 begin to approach each other, and the first servo motor is turned off after the two vertical LED display unit boards 14 are in contact with each other, thus completing the splicing of the entire display panel.

[0031] Compared with the related art, the splicing structure of the LED display screen provided by the utility model has the following beneficial effects:

[0032] The utility model provides a splicing structure of an LED display screen, and through the plug-in cooperation between the provided plug-in plate 13 and the retaining slot 12, the LED display screen unit plate 14 can be quickly placed at a specified installation position, and then the positioning column 17 is automatically inserted into the limiting slot 15 by retracting the output shaft of the electric push rod 9, thereby completing the fixation of the LED display screen unit plate 14, so that the splicing work of the LED display panel can be quickly completed, and through the design of the vertical bidirectional lead screw 3 and the linkage plate 4, as well as the design of the transverse bidirectional lead screw 6 and the sliding seat 7, LED display screen unit plates 14 of different sizes can be installed, thereby being able to meet people's diverse needs.
