[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention belong to the scope of protection of the present invention.

[0023] Embodiments of the present invention:

[0024] Embodiment 1

[0025] As Figure 1 、 2 As shown in Figures 5, a control card for an LED display screen that is convenient for installation includes a substrate 1 installed in an LED display screen (the LED display screen belongs to the prior art and will not be described in detail in this application). Installation holes 2 are provided at the four corners of the substrate 1. Through the arrangement of the four installation holes 2, multiple positions on the substrate 1 can be fixed, thereby improving the fixing effect and reducing the situation of the substrate 1 shaking. An installation ring 3 is installed inside the installation hole 2.

[0026] Specifically: The installation ring 3 includes two ring bodies 31, and the two ring bodies 31 are respectively located above and below the installation hole 2. A fixing ring 32 is fixed between the two ring bodies 31, and the fixing ring 32 is located inside the installation hole 2 and is coaxially arranged. The outer side of the fixing ring 32 and the opposite sides of the two ring bodies 31 are fixed on the substrate 1, thereby playing a role in fixing the installation ring 3.

[0027] A plurality of installation plates 5 are fixed on the inner side wall of the fixing ring 32 at equal intervals along the axial direction. There is a certain gap between adjacent installation plates 5. The tops of the plurality of installation plates 5 are fixedly connected to the same fixing plate 6, and a rotating column 11 is fixed at the center of the top of the fixing plate 6. The top end of the rotating column 11 is rotatably connected to the center of the inner top wall of the rotating cylinder 7, and the fixing plate 6 and the plurality of installation plates 5 are located inside the rotating cylinder 7. A plurality of columns of clamping blocks 8 are arranged at equal intervals along the circumferential direction on the inner side wall of the rotating cylinder 7. A plurality of card slots 10 are arranged at equal intervals on the outer surface of the installation plate 5. In the initial state, the clamping blocks 8 are located in the card slots 10 on the outer surface of the installation plate 5. The end of the clamping block 8 is provided with a rounded corner. Through the setting of the rounded corner, when the clamping block 8 rotates along the axis of the rotating column 11 and is clamped into the card slot 10 on the outer surface of the plug board 9, the edge of the card slot 10 located on the plug board 9 can squeeze the circular surface of the clamping block 8, so that the clamping block 8 can be inserted into the card slot 10 more smoothly. It should be noted that the length of the clamping block 8 is less than the length of the card slot 10 located in it; to prevent interference during the installation of the plug board 9 due to the excessive length of the clamping block 8.

[0028] The mounting post 4 is fixed inside the LED display screen, and a plurality of insertion plates 9 are fixedly arranged on the outer surface of the mounting post 4 at equal intervals in the circumferential direction, and a plurality of card slots 10 are formed on the outer surface of the insertion plate 9.

[0029] When installing the substrate 1, first insert the mounting rings 2 on the substrate 1 onto the mounting posts 4 respectively, so that the insertion plates 9 on the outer surface of the mounting post 4 are inserted between the adjacent mounting plates 5. When the card slots 10 on the outer surface of the insertion plate 9 are aligned with the card slots 10 on the outer surface of the mounting plate 5, then rotate the rotating cylinder 7, so that the multiple clamping blocks 8 in the rotating cylinder 7 rotate along the axis of the rotating column 11, and each clamping block 8 can be clamped between the corresponding card slots 10, thus playing a role in fixing the substrate 1.

[0030] Embodiment 2

[0031] As Figure 2 、 3 As shown in Fig. -5: A control card for an LED display screen that is easy to install, including a substrate 1 inside the LED display screen (the LED display screen belongs to the prior art and will not be described in detail in this application). Mounting holes 2 are formed at the centers of both ends of the substrate 1. An installation ring 3 is installed inside each mounting hole 2 (the installation ring 3 has the same structure as that in Embodiment 1 and will not be described in detail in this embodiment). An installation post 4 is inserted inside the installation ring 3. A plurality of insertion plates 9 are fixedly arranged on the outer surface of the installation post 4 at equal intervals in the circumferential direction, and a plurality of card slots 10 are formed at equal intervals on the outer surface of each insertion plate 9.

[0032] An installation plate 5 is installed inside the installation ring 3 along the axial direction, and a certain gap is left between adjacent installation plates 5. The tops of the multiple installation plates 5 are fixedly connected to the same fixing plate 6, and a rotating column 11 is fixedly arranged at the center of the top of the fixing plate 6. The center of the inner side wall of the rotating cylinder 7 is rotatably installed on the rotating column 11, and a torsion spring 12 is sleeved on the outer surface of the rotating column 11. The two ends of the torsion spring 12 are respectively inserted into the fixing sleeves 13, and the two fixing sleeves 13 are respectively fixed on the top of the fixing plate 6 and the inner top wall of the rotating cylinder 7.

[0033] When installing the substrate 1, the staff rotate the rotating cylinder 7 with both hands respectively, so that while the rotating cylinder 7 drives a plurality of clamping blocks 8 to rotate, it can also act on the torsion spring 12. When the torsion spring 12 is subjected to a squeezing force, it changes from the original state to the squeezed state, so that the multiple clamping blocks 8 on the rotating cylinder 7 respectively rotate into the clamping grooves 10 on the mounting plate 5. Then, the mounting holes 2 on the substrate 1 are respectively inserted into the mounting posts 4, so that the insertion plates 9 on the mounting posts 4 are respectively inserted between adjacent mounting plates 5. If the clamping grooves 10 on the insertion plates 9 are aligned with the clamping grooves 10 on the mounting plates 5, then the rotating cylinder 7 is released. The torsion spring 12 loses the squeezing force, changes from the squeezed state to the original state and drives the rotating cylinder 7 to rotate in the reverse direction, so that the rotating cylinder 7 can rotate on the rotating column 11. The rotating cylinder 7 drives a plurality of clamping blocks 8 to rotate, so that the clamping blocks 8 are clamped between the two corresponding clamping grooves 10, thus completing the fixing work of the substrate 1.
