Detailed implementation manner

[0020] 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] The present invention provides an LED display box installation device as Figures 1-4 shown, including a lamp bead 1 and a fixing plate 3;

[0022] Lamp beads 1 are densely arranged at the front ends of two fixing plates 3, and box bodies 4 are arranged at the upper, lower, left, and right side edges of the front ends of the two fixing plates 3;

[0023] Knobs 8 are arranged on the front sides of multiple box bodies 4. A rotating shaft 18 is arranged between the front and rear ends of the inner walls of multiple box bodies 4. The front end of the rotating shaft 18 is fixedly connected to the knob 8. A connecting plate 17 is arranged on the surface of the rotating shaft 18. Two connecting grooves 5 are opened on the outer surface of each of the multiple box bodies 4. The rotating shaft 18 can drive the connecting plate 17 to rotate out of the connecting groove 5 and be inserted into the connecting groove 5 of the opposite box body 4 for fixation.

[0024] After the fixing plates 3 are spliced, the knob 8 can be rotated. The knob 8 drives the connecting plate 17 on the outer wall of the rotating shaft 18 to rotate, so that the connecting plate 17 rotates out of the connecting groove 5 and enters the opposite box body 4 for fixation. Fixing the bottom plates in this way can prevent the front and rear misalignment in the middle of the fixing plate 3.

[0025] As Figure 2 and Figure 4 shown, hanging rods 15 are arranged on the upper sides of the front and rear ends of the inner walls of multiple box bodies 4. Card slots 16 are opened at the lower edge of the connecting plate 17. The connecting plate 17 is fixedly connected by clamping the hanging rod 15 through the card slot 16. The box body 4, the connecting plate 17, and the knob 8 are all made of stainless steel. The box body 4 is fixedly connected to the fixing plate 3 by welding.

[0026] After the connecting plate 17 is rotated into the opposing box body 4, the card slot 16 on the surface of the connecting plate 17 will hang on the outer wall of the hanging rod 15 on the inner wall of the box body 4 for fixation, thus preventing the connecting plate 17 from detaching. The box body 4, connecting plate 17, and knob 8 made of stainless steel can avoid rusting when used outdoors.

[0027] As Figure 1 and Figure 2 shown, at the four corners of the front ends of the two fixing plates 3, fixing blocks 2 are provided. Between the two fixing plates 3, a fixing rod 6 is provided at the front side. On the outer wall of the fixing rod 6, two connecting blocks 7 are provided. The connecting blocks 7 are used to fit and fix to the fixing blocks 2. A plurality of screw holes 14 are opened at the front ends of the fixing blocks 2. A plurality of bolts 9 are provided at the front ends of the two connecting blocks 7. The fixing blocks 2 and the connecting blocks 7 are fixedly connected by screwing the bolts 9 into the screw holes 14.

[0028] When connecting and fixing the fixing plate 3 and the fixing rod 6, align the fixing blocks 2 and the connecting blocks 7 and fix them by screwing the bolts 9 from the front end of the connecting blocks 7 into the screw holes 14 of the fixing blocks 2.

[0029] As Figure 2 shown, in the middle of the front ends of the two fixing plates 3, control boxes 12 are provided. On the front ends of the two control boxes 12, heat dissipation fins 13 are provided. The heat dissipation fins 13 are used to increase the heat dissipation efficiency of the control boxes 12. On the upper sides of the right ends of the two control boxes 12, series slots 10 are opened. The series slots 10 are used to plug in series data lines. Below the two series slots 10, power holes 11 are provided. The power holes 11 are used to plug in power cords.

[0030] After the fixing plates 3 are spliced and fixed, the series line can be plugged into the series slot 10 to connect multiple fixing plates 3 in series, and then the power cord is inserted into the power hole 11 to energize the control box 12. After the control box 12 is energized, it will drive the lamp beads 1 to light up, and the heat dissipated by the control box 12 will be dissipated outward through the heat dissipation fins 13.

[0031] Working principle of the utility model: When connecting and fixing the fixing plate 3 and the fixing rod 6, align the fixing block 2 with the connecting block 7 and fix them by screwing the bolt 9 into the screw hole 14 of the fixing block 2 from the front end of the connecting block 7. After the fixing plates 3 are spliced, the knob 8 can be rotated, causing the connecting plate 17 on the outer wall of the rotating shaft 18 to rotate, so that the connecting plate 17 rotates out of the connecting groove 5 and enters the box body 4 on the opposite side for fixing. After the connecting plate 17 rotates into the box body 4 on the opposite side, the card slot 16 on the surface of the connecting plate 17 will hang on the outer wall of the hanging rod 15 on the inner wall of the box body 4 for fixing, thereby preventing the connecting plate 17 from detaching. By fixing the bottom plates in this way, the front and back misalignment in the middle of the fixing plate 3 can be prevented. After the fixing plates 3 are spliced and fixed, the series connection wires can be inserted into the series connection slots 10 to connect multiple fixing plates 3 in series, and then the power cord is inserted into the power hole 11 to power on the control box 12. After the control box 12 is powered on, it will drive the lamp beads 1 to light up, and the heat dissipated by the control box 12 will be dissipated outward through the heat dissipation fins 13.

[0032] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
