[0028] In order to make good use of the space for installing the LED screen on site, a small cabinet was designed because the same cabinet does not have enough space to install the entire screen. The small cabinet can meet the customer's requirements for screen space utilization. In order to make the splicing between the large cabinet and the small cabinet more convenient, with better flatness and display effect, the cabinet is locked and connected to the left and right cabinets on a plane through a square tube and a connecting piece, which greatly saves the time for splicing and installation between cabinets and reduces labor costs.

[0029] like Figure 1 , Figure 2 as well as Figure 4 As shown, in this embodiment, the LED display unit includes: a box body 10, an LED display module 20, a cover plate 30 and a plurality of strip holes 50. An opening 11 is provided on the rear side of the box body 10. The LED display module 20 is installed on the front side of the box body 10. The cover plate 30 is detachably installed at the opening 11, and a heat dissipation portion 40 is provided on the cover plate 30. The plurality of strip holes 50 are arranged at intervals on the rear side of the box body 10 and are located on the periphery of the cover plate 30.

[0030] By applying the technical solution of this embodiment, the LED display module 20 is installed on the front side of the box 10, an opening 11 is provided on the rear side of the box 10, the cover plate 30 is detachably installed at the opening 11, and a heat dissipation portion 40 is provided on the cover plate 30. A plurality of strip holes 50 are arranged at intervals on the rear side of the box 10 and are located on the outer periphery of the cover plate 30. Through the above arrangement, the heat dissipation portion 40 can achieve heat dissipation. The strip holes 50 can be connected to the bracket and there is still a gap after the connection, so that the heat can also be discharged through the above gap, that is, the heat dissipation portion 40 and the strip holes 50 can be circulated, so that the heat inside the box 10 can be discharged more easily, and the electrical components inside the box 10 can be prevented from being damaged. Therefore, the technical solution of this embodiment effectively solves the problem of poor heat dissipation effect of small-sized boxes in the related art.

[0031] Specifically, the size of the box in this embodiment is 320×640.

[0032] In this embodiment, there is a square hole between the box bodies 10 and 10, and the arrangement of the strip-shaped hole 50 facilitates the maintenance and disassembly of the LED display module.

[0033] If the box 10 is used indoors and is a small box, the heat generated by the power supply and the lamp inside the box 10 must be dissipated in time. If the heat inside the box 10 is not discharged in time, it is easy to cause the service life of the components (power supply, IC, lamp, capacitor, etc.) inside the box 10 to be shortened. If the temperature outside the box 10 rises, it may affect the normal operation of the box LED screen. Therefore, a plurality of strip holes 50 are designed to facilitate the disassembly and assembly of the LED display module 20. At the same time, under the action of the heat dissipation part 40, it also plays a role in air circulation and rapid heat dissipation. The heat dissipation part 40 is irregularly arranged, and the openings of different sizes improve air circulation and increase the heat dissipation speed.

[0034] Specifically, in this embodiment, the box body 10 and the cover plate 30 are made of iron or aluminum. When iron is used, the thickness is 1.2 mm, and when aluminum is used, the thickness is 2 mm.

[0035] like Figure 1 , Figure 2 as well as Figure 4 As shown, in this embodiment, the opening 11 is located in the middle of the box 10, and the strip holes 50 are arranged on both sides of the cover plate 30 along the width direction of the box 10, and the strip holes 50 extend along the width direction of the box 10. The above arrangement can achieve better heat dissipation, and can achieve the adjustable position of the box 10, so that multiple LED display units can be closely fitted when spliced, thereby ensuring the display effect.

[0036] like Figure 4 and Figure 5As shown, in this embodiment, the heat dissipation portion 40 includes a plurality of first heat dissipation holes 41 and a plurality of second heat dissipation holes 42, the first heat dissipation holes 41 and the second heat dissipation holes 42 are arranged adjacent to each other and have a gap, and the area of ​​the first heat dissipation holes 41 is smaller than the area of ​​the second heat dissipation holes 42. The above arrangement can achieve a better heat dissipation effect.

[0037] like Figure 4 and Figure 5 As shown, in this embodiment, the first heat dissipation hole 41 is a strip heat dissipation hole, and the second heat dissipation hole 42 is a rectangular heat dissipation hole. The above shapes can improve the heat dissipation effect.

[0038] Of course, in an embodiment not shown in the figure, the shape of the first heat dissipation hole 41 can be circular, elliptical, rectangular, sawtooth or other shapes, and the shape of the second heat dissipation hole 42 can be circular, elliptical, rectangular, sawtooth or other shapes.

[0039] like Figure 4 and Figure 5 As shown, in this embodiment, the plurality of first heat dissipation holes 41 include a plurality of first heat dissipation groups 411 and a plurality of second heat dissipation groups 412, the first heat dissipation group 411 includes a plurality of first heat dissipation holes 41 extending along a first direction, the plurality of first heat dissipation groups 411 are arranged at intervals along the width direction of the box body 10, the second heat dissipation group 412 includes a plurality of first heat dissipation holes 41 extending along a second direction, the plurality of second heat dissipation groups 412 are arranged at intervals along the width direction of the box body 10, wherein the first direction is arranged at an angle to the second direction. The above arrangement can make the overall layout more reasonable and can ensure the heat dissipation effect. Specifically, the first direction is perpendicular to the second direction.

[0040] Specifically, in this embodiment, a plurality of heat dissipating portions 40 are arranged at intervals.

[0041] like Figure 4 and Figure 5 As shown, in this embodiment, at least two first heat dissipation holes 41 are arranged on the side of each second heat dissipation hole 42. In this way, the structural strength of the cover plate 30 can be ensured while taking into account the heat dissipation effect.

The arrangement of the surrounding wall 12 can ensure the structural strength of the box body 10 and can make the position of the cover plate 30 more stable.

[0043] like Figure 2 and Figure 3As shown, in this embodiment, a plug-in structure 60 and a connection structure 70 are disposed between the cover plate 30 and the surrounding wall 12 , and the plug-in structure 60 and the connection structure 70 are disposed opposite to each other. The above arrangement can effectively connect the cover plate 30 to the surrounding wall 12 .

The above-mentioned first connection holes 13 can realize the connection between adjacent boxes 10, and the positioning columns 91 can position the adjacent boxes 10, thereby making the flatness of the boxes 10 better after splicing.

[0046] Specifically, in this embodiment, the box 10 is formed by sheet metal bending and welding. After forming, the positioning column 91 is welded, the reinforcing sheet 80 is welded, the interlocking strength of the box 10 is increased, the power adapter plate locking studs are riveted, the receiving card locking studs are riveted, the rear cover locking studs are welded, and finally the wire tie ring is welded.

The power adapter plate is formed by sheet metal stamping. The power supply and the adapter plate are assembled into a whole, and then locked to the box 10 by screws and studs. The power socket is locked to the box by screws. The receiving card is locked to the box 10 by screws and nut columns. The cover plate 30 is locked by screws and studs. Before locking, the plug plate 62 must be inserted into the jack 61. The LED display module 20 is locked to the box 10 by screws, and the entire box 10 is completed.

[0047] The power adapter plate can be processed from iron or aluminum. When iron is used, the thickness is 1.2 mm, and when aluminum is used, the thickness is 1.5 mm.

[0048] The technical solution of this embodiment is to design the original large box into a small box cut in half, which solves the problem of insufficient installation space for the entire LED screen, saves installation time, and reduces costs. The small box and the large box are locked by screws and nuts, and then locked and locked by connecting pieces to form a whole LED screen. The box 10 is installed on the steel structure, which can protect the box 10, prevent the box 10 from loosening, and ensure that the box 10 can work normally. The wiring of the box 10 can be done through the aviation plug, up and down wiring, and the connection between the boxes 10 is simple, convenient, and flexible.
