[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0035] like Figures 1 to 7 As shown, applying the technical solution of this embodiment, the box of the LED display device includes a frame and an indicator light assembly 20. A handle groove 11 is provided at the rear of the frame, and the handle groove 11 extends from the rear of the frame to the front of the frame. A mounting opening is provided on the groove wall of the handle groove 11. The indicator light assembly 20 includes a circuit board 21 and a lamp holder 22 provided on the circuit board 21, the circuit board 21 is connected to the frame, and the lamp holder 22 passes through the mounting opening and extends into the handle groove 11.

[0036] In this way, the setting of the handle groove 11 facilitates the operator to hold the frame, so as to facilitate the operator to carry the frame. The lamp head 22 can be inserted into the handle groove 11, avoiding the situation in the related art where the lamp head protrudes from the rear surface of the box body, and reducing the problem of squeezing and bumping the lamp head when multiple boxes are stacked. In addition, the lamp head 22 is inserted into the handle groove 11 to facilitate the operator to observe the display of the lamp head 22. Therefore, the technical solution of this embodiment effectively solves the problem in the related art that the indicator light assembly is easily damaged when multiple boxes are stacked.

[0037] like Figures 1 to 7As shown, the frame includes a first frame edge 101, a second frame edge 102, a third frame edge 103 and a fourth frame edge 104 connected in sequence, and the handle groove 11 is arranged on the first frame edge 101. The structure of the frame is simple and easy to process. The handle groove 11 includes a first side wall 111, a second side wall 112, a third side wall 113 and a fourth side wall 114 connected in sequence. The handle groove 11 has a simple structure and is easy to process. The third side wall 113 is located below the first side wall 111, the circuit board 21 is connected to the outer surface of the third side wall 113, and the mounting port is arranged on the third side wall 113. This can further facilitate the operator to observe the lamp holder 22 extending from the mounting port.

[0038] In this embodiment, the first side wall 111 is a part of the first frame edge 101. In other embodiments, the first side wall 111 is disposed below the first frame edge 101 at intervals.

[0039] like Figures 1 to 7 As shown, the installation opening is an installation notch 115 that passes through the rear edge of the third side wall 113. The installation notch 115 is provided to facilitate the installation of the lamp holder 22 and improve the installation efficiency. The box of the LED display device also includes a rear cover 30 that is detachably covered on the rear side of the frame. When the rear cover 30 is covered on the rear side of the frame, the front edge of the rear cover 30 blocks the installation notch 115. The provision of the rear cover 30 can further limit the displacement of the lamp holder 22, so that the installation of the indicator light assembly 20 on the frame is more stable and reliable.

[0040] In other embodiments, the mounting opening is a closed through hole.

[0041] like Figures 1 to 7 As shown, the first side wall 111 is provided with a safety rope through hole 40 penetrating the upper surface and the lower surface of the first side wall 111. The provision of the safety rope through hole 40 facilitates the connection of the safety rope with the frame.

[0042] like Figures 1 to 7 As shown, the hole wall of the safety rope through hole 40 includes a straight surface section 41 and a curved surface section connected to the straight surface section 41, and at least part of the curved surface section is arranged to protrude backward. In this way, when the LED display device is hoisted, at least part of the safety rope passed through the safety rope through hole 40 can be stuck in the curved surface section protruding backward, reducing the shaking of the safety rope in the safety rope through hole 40, limiting the movement of the safety rope, and making the LED display device more stable when hoisted.

[0043] like Figures 1 to 7As shown, the curved surface segment includes a plurality of arc surface segments 42 connected in sequence, the first of the plurality of arc surface segments 42 is connected to the first end of the straight surface segment 41, and the last of the plurality of arc surface segments 42 is connected to the second end of the straight surface segment 41. The arrangement of the plurality of arc surface segments 42 facilitates the processing of the safety rope through hole 40, and makes the force on the hole wall of the safety rope through hole 40 more uniform, thereby improving the structural strength of the frame.

[0044] In this embodiment, there are three arc surface segments 42, the first arc surface segment 42 is connected to the first end of the straight surface segment 41, the third arc surface segment 42 is connected to the second end of the straight surface segment 41, the second arc surface segment 42 is arranged opposite to the straight surface segment 41, and the second arc surface segment 42 is arranged to protrude backward.

[0045] like Figures 1 to 7 As shown, the frame also includes a connecting longitudinal beam 106 connected between the first frame edge 101 and the third frame edge 103 and a connecting cross beam 105 connected between the second frame edge 102 and the fourth frame edge 104. An operation port 107 is formed between the first frame edge 101, the second frame edge 102, the third frame edge 103, the fourth frame edge 104, the connecting cross beam 105 and the connecting longitudinal beam 106. The arrangement of the connecting longitudinal beam 106 and the connecting cross beam 105 can improve the structural strength of the frame. The operator can maintain the components in the box through the operation port 107, which is convenient for the operator to perform maintenance operations on the LED display device at the front or rear side of the LED display device.

[0046] In this embodiment, a plurality of light panels are spliced ​​and arranged on the box body. A plurality of support platforms 91 of equal height in the front-to-back direction are arranged on the front side of the connecting crossbeam 105 and the connecting longitudinal beam 106, and a groove 92 is arranged on the support platform 91. The splicing seam of two adjacent light panels is located on the front side of the groove 92. The arrangement of the groove 92 enables the light at the splicing seam of two adjacent light panels to be diffusely reflected in the groove 92, thereby preventing the light from being emitted through the splicing seam and affecting the display effect. The bottom wall of the groove 92 is a plane, and the two side walls of the groove 92 are inclined surfaces. The distance between the two side walls of the groove 92 gradually decreases along the direction from the opening of the groove 92 to the bottom wall of the groove 92, so as to further improve the light absorption effect.

[0047] like Figures 1 to 7As shown, the connection between the first frame edge 101 and the second frame edge 102 is provided with a first chamfered bevel 51, and the connection between the second frame edge 102 and the third frame edge 103 is provided with a second chamfered bevel 52. The setting of the first chamfered bevel 51 reduces the burrs at the connection between the first frame edge 101 and the second frame edge 102, and reduces the possibility of gaps when multiple boxes are spliced ​​due to the non-right angle at the connection between the first frame edge 101 and the second frame edge 102. The setting of the first chamfered bevel 51 can reduce the machining accuracy of the connection between the first frame edge 101 and the second frame edge 102. The setting of the second chamfered bevel 52 reduces the burrs at the connection between the second frame edge 102 and the third frame edge 103, and reduces the possibility of gaps when multiple boxes are spliced ​​due to the non-right angle at the connection between the second frame edge 102 and the third frame edge 103. The setting of the second chamfered bevel 52 can reduce the machining accuracy of the connection between the second frame edge 102 and the third frame edge 103. A first reinforcing rib 61 extending toward the third frame edge 103 is provided on the inner surface of the first frame edge 101, a second reinforcing rib 62 extending toward the fourth frame edge 104 is provided on the inner surface of the second frame edge 102, a third reinforcing rib 63 extending toward the first frame edge 101 is provided on the inner surface of the third frame edge 103, and a fourth reinforcing rib 64 extending toward the second frame edge 102 is provided on the inner surface of the fourth frame edge 104. The provision of the first reinforcing rib 61, the second reinforcing rib 62, the third reinforcing rib 63 and the fourth reinforcing rib 64 can improve the structural strength of the box body, improve the tensile strength of the box body, reduce the material used for the box body, reduce the weight of the box body, and reduce the production cost.

[0048] In other embodiments, a first chamfered slope 51 is provided at the connection between the first frame edge 101 and the second frame edge 102, and a second chamfered slope 52 is provided at the connection between the second frame edge 102 and the third frame edge 103. Alternatively, a first reinforcing rib 61 extending toward the third frame edge 103 is provided on the inner surface of the first frame edge 101, a second reinforcing rib 62 extending toward the fourth frame edge 104 is provided on the inner surface of the second frame edge 102, a third reinforcing rib 63 extending toward the first frame edge 101 is provided on the inner surface of the third frame edge 103, and a fourth reinforcing rib 64 extending toward the second frame edge 102 is provided on the inner surface of the fourth frame edge 104.

[0049] In this embodiment, the first frame edge 101, the second frame edge 102, the third frame edge 103, the fourth frame edge 104, the connecting cross beam 105, the connecting longitudinal beam 106, the first reinforcing rib 61, the second reinforcing rib 62, the third reinforcing rib 63 and the fourth reinforcing rib 64 are an integrally formed part. The frame is an aluminum part formed by die casting.

[0050] like Figures 1 to 7As shown, the first frame edge 101 is provided with a first avoidance hole 71 for avoiding the plug of the wire 80, and the third frame edge 103 is provided with a second avoidance hole 72 for the wire 80 to pass through. In this way, the plug of the wire 80 can be extended from the first avoidance hole 71, so as to facilitate the plugging and matching of the external device with the plug of the wire 80. The second avoidance hole 72 is provided to facilitate the wire 80 to pass through the box.

[0051] In this embodiment, when the operator is at the rear side of the LED display device, the operator can perform installation and removal operations on the wire 80 through the operation port 107 .
