[0022] The present invention will be further described with reference to the following examples and accompanying drawings:

[0023] A highly reliable LED splicing floor, such as Figures 1 to 3As shown, it includes: a plurality of matrix-joined LED display modules 10, a PC mask 11 fixed on the LED display module 10, and a support frame 20 supporting the LED display module 10. The LED display module 10 includes an LED display body 12 and support feet 13 arranged at four corners below the LED display body 12. The bottom of the support foot 13 is provided with a first mounting hole 14. The four corners of the support frame 20 are provided with first mounting grooves 21. The LED splicing floor with high reliability is also provided with a first positioning column 30. The first positioning column 30 includes a lower vertebral body 31 that cooperates with the first mounting groove 21 and a first upper column 32 that cooperates with the first mounting hole 14. The diameter of the thicker end of the lower vertebral body 31 is larger than the diameter of the first upper column 32. The first upper column 32 is arranged at the center of the thick end 33 of the lower vertebral body 31. The first upper column 32 is inserted into the first mounting hole 14. The end face of the supporting foot 13 is blocked on the thick end 33 of the lower vertebral body 31, and the thinner end of the lower vertebral body 31 is inserted into the first mounting groove 21.

[0024] The LED splicing floor with high reliability of the present invention adds a PC mask 11 to the LED display module 10, which can not only play a dustproof and waterproof effect, but also increase the strength and pressure resistance of the LED splicing floor. The LED splicing floor with high reliability of the present invention is provided with a support frame 20 below the LED display module 10, and the support frame 20 and the LED display module 10 are connected through the first positioning column 30. When connecting, it is only necessary to insert the first upper column 32 of the first positioning column 30 into the first mounting hole 14 of the LED display module 10, and insert the thinner end of the lower cone 31 of the first positioning column 30 into the first mounting groove 21 to complete. After the connection, the end face of the support foot 13 of the LED display module 10 is blocked on the thick end 33 of the lower cone 31, and the first positioning column 30 is inserted into the first mounting hole 14 and the first mounting groove 21, which will not affect the appearance, and realize the seamless connection between the support frame 20 and the LED display module 10. The connection structure of the support frame 20 and the LED display module 10 is simple, and the connection operation is very convenient. In addition, the high-reliability LED splicing floor of the present invention is provided with a support frame 20 under the LED display module 10 to prevent the LED display module 10 from directly contacting the floor, and reduces the direct friction with the floor during installation, disassembly, position adjustment and use, thereby reducing the wear and deformation of the LED display module 10 and making it less prone to damage. At the same time, the strength, firmness, stability and load-bearing and pressure-resistant capacity of the overall structure of the high-reliability LED splicing floor of the present invention are significantly increased, thereby extending the service life.

[0025] Preferably, if Figures 1 to 3As shown, the four sides of the support frame 20 are all provided with support blocks 40 for supporting the LED display body 12. The LED display module 10 includes an LED display body 12 and support feet 13 provided at the four corners below the LED display body 12. There is a suspended space between the four sides of the support frame 20 and the LED display body 12, which is a weak part of the LED splicing floor under stress. The pressure resistance here is poor, and the LED display body 12 is easily deformed by pressure. Therefore, the support blocks 40 for supporting the LED display body 12 are provided on the four sides of the support frame 20, which can play a good supporting and compressive resistance role, can enhance the structural firmness and stability of the LED splicing floor with high reliability of the present invention, improve the overall pressure resistance of the product, and improve the durability of the product.

[0026] Preferably, if Figures 1 to 5 As shown, the LED splicing floor with high reliability of the present invention is also provided with a second positioning column 50 and a mounting foot 60. Each mounting foot 60 supports a corner of four adjacent support frames 20. Four first threaded holes 61 are provided at the upper end of the mounting foot 60. The four corners of the bottom surface of the support frame 20 are respectively provided with a second mounting groove 22. The second positioning column 50 includes a second upper column 51 that cooperates with the second mounting groove 22, a rotating ring 52 located in the middle, and a lower external threaded column 53 that cooperates with the first threaded hole 61. The second upper column 51 is inserted into the second mounting groove 22, and the lower external threaded column 53 is screwed into the first threaded hole 61.

[0027] After the support frame 20 is spliced, Figure 2 As shown, the four first threaded holes 61 on each mounting foot 60 are respectively fixed to a corner of four adjacent support frames 20 through the second positioning column 50, that is, the LED display modules 10 installed with the support frames 20 are spliced ​​together by fixing the mounting foot 60 with the support frames 20. Compared with the prior art that directly places the LED display modules 10 on the ground and randomly places them, the mounting foot 60 of the LED splicing floor with high reliability of the present invention can not only play a supporting role, but also play a role in positioning the LED display modules 10, and can realize the seamless connection of the LED splicing floor, which is convenient for the installation, disassembly and movement of the LED splicing floor with high reliability of the present invention.

[0028] Since the second upper column 51 of the second positioning column 50 is inserted into the second mounting groove 22 at the four corners of the bottom surface of the support frame 20, and the lower external thread column 53 of the second positioning column 50 is screwed into the first threaded hole 61 at the upper end of the mounting foot 60, when installing the LED splicing floor with high reliability of the present invention, the lower external thread column 53 of the second positioning column 50 can be screwed into or out of the first threaded hole 61 at the upper end of the mounting foot 60 by rotating the rotating ring 52 located in the middle of the second positioning column 50, thereby adjusting the horizontal height of the support frame 20 and the LED display module 10. To adjust the horizontal height of the support frame 20 and the LED display module 10, it is only necessary to rotate the rotating ring 52 clockwise or counterclockwise, which is simple and convenient to operate, and the adjustment effect is very good. This structure facilitates the leveling and alignment of the LED splicing floor with high reliability of the present invention during installation, and ensures the flatness of the LED splicing floor after splicing when the LED display module 10 has manufacturing errors, assembly errors and installation errors.

[0029] Preferably, if Figures 1 to 5 As shown, the mounting foot 60 includes a base 62, a threaded rod 63, a rotating cylinder 64 having a through hole 65 cooperating with the threaded rod 63, and an adjusting disk 66 fixed on the rotating cylinder 64. A first threaded hole 61 is arranged at the upper end of the adjusting disk 66. A first external threaded column 67 is fixedly provided at the middle part of the base 62. A first internal thread (not shown in the figure) cooperating with the first external threaded column 67 is provided at the lower part of the threaded rod 63. The threaded rod 63 is inserted into and fixed in the through hole 65 of the rotating cylinder 64. The first external threaded column 67 is screwed into the first internal thread (not shown in the figure).

[0030] The adjusting disk 66 is fixed on the rotating cylinder 64, the threaded rod 63 is inserted into and fixed in the through hole 65 of the rotating cylinder 64, and the middle part of the base 62 is fixed with a first external thread column 67 which is screwed into the first internal thread (not shown in the figure) of the threaded rod 63, that is, by rotating the rotating cylinder 64, the first external thread column 67 is screwed into or out of the first internal thread (not shown in the figure) of the threaded rod 63, so that the horizontal height of the rotating cylinder 64 can be adjusted, and then the horizontal height of the adjusting disk 66 can be adjusted, and the horizontal height of the support frame 20 and the LED display module 10 can be adjusted. Therefore, if the horizontal height of the support frame 20 and the LED display module 10 needs to be adjusted in a large range, it is only necessary to rotate the rotating cylinder 64 clockwise or counterclockwise, which is simple and convenient to operate, and the adjustment effect is very good. This structure facilitates the large-scale leveling and alignment of the highly reliable LED splicing floor during installation of the present invention, and ensures the flatness of the LED splicing floor after splicing when the LED display module 10 has manufacturing errors, assembly errors and installation errors.

[0031] In summary, when installing the highly reliable LED splicing floor of the present invention, coarse adjustment can be performed by rotating the rotating cylinder 64 and fine adjustment can be performed by rotating the rotating ring 52, so that the LED display module 10 can be accurately leveled and aligned to ensure the flatness of the LED splicing floor.

[0036] Preferably, if Figure 5 As shown, there are six adjusting arms 69, which are evenly spaced and arranged on the outer circumference of the rotating cylinder 64. In this way, during the rotation of the adjusting arms 69, the operator does not need to change the position all the time, and can find two opposite adjusting arms 69 with appropriate force to operate, which is very convenient and fast, and the assembly and adjustment efficiency is high.

[0037] Preferably, if Figure 3 and Figure 5 As shown, an anti-skid pad 90 is provided at the bottom of the mounting foot 60. The anti-skid pad 90 can increase the friction and adhesion of the bottom of the mounting foot 60, making it easier to position the LED splicing floor, thereby ensuring the overall stability of the LED splicing floor with high reliability of the present invention.
