Referring to fig. 1 to 4, fig. 1 is a schematic structural diagram illustrating an LED display module box in a first position of a supporting member according to an embodiment of the present invention, fig. 2 is a partially enlarged view of a position a in fig. 1, fig. 3 is a schematic structural diagram illustrating the LED display module box in a second position of the supporting member according to an embodiment of the present invention, and fig. 4 is a partially enlarged view of a position B in fig. 3. The LED display module box 10 comprises a frame 12 and a handle 11, wherein the handle 11 is arranged on the frame 12, the handle 11 comprises a holding handle 100 and a propping piece 200, the propping piece 200 is connected with the holding handle 100 in a sliding manner, the propping piece 200 has two limit positions relative to the holding handle 100 in a sliding manner, specifically, in the process that the propping piece 200 slides relative to the holding handle 100, the propping piece 200 moves relative to the holding handle 100 in a telescopic manner, namely, the propping piece 200 has a position extending out of the holding handle 100 and is recorded as a first position, and a position retracting into the holding handle 100 and is recorded as a second position. It should be noted that "extending" and "retracting" herein refer to at least a portion of the structure of the abutting member 200 extending from or retracting to the handle 100 from the abutting member 200, and are not limited to the abutting member 200 extending out of the handle 100 and the abutting member 200 retracting back into the handle 100. When the abutting piece 200 is in the first position, at least part of the projection of the abutting piece 200 on the plane of the frame 12 is outside the peripheral outline of the frame 12; when the supporting member 200 is at the second position, the projection of the supporting member 200 on the plane of the frame 12 falls into the outer contour of the frame 12, so that the supporting member 200 does not interfere with the splicing of the LED display module. In the present embodiment, the outer contour of the frame 12 refers to the projection of the outermost sidewall of the frame 12 in the plane of the frame 12.
According to the LED display module box body 10, in the transportation process of the LED display module, the abutting piece 200 of the handle 11 is arranged at the first position, the frame 12 of the LED display module box body 10 is kept away, the LED lamp beads of the LED display module are prevented from being subjected to lateral force in the transportation process, and the damage probability of the LED lamp beads at the edge is further reduced. Taking the transportation process of the LED display module as an example, before the edge of the LED display module is wrapped by the packing material, the abutting member 200 is placed at the first position, so that the top plate 210 protrudes out of the frame 12, and the LED lamp beads at the edge of the LED display module cannot touch the packing material, thereby reducing the damage probability of the LED display module. Because the LED lamp beads at the edge are better protected, the LED lamp beads can be arranged at the position closer to the edge, namely, the LED display module can be provided with a narrower frame. When a plurality of LED display module assemblies with narrower frames are spliced and displayed, the display effect of the edge splicing positions of the LED display module assemblies is more consistent with the display effect of the middle positions of the LED display module assemblies. In the installation and maintenance process, the abutting piece 200 is arranged at the second position, the abutting piece 200 is completely retracted to the grab handle 100, the abutting piece 200 cannot interfere with splicing of the LED display module, the LED display module is installed and maintained through the grab handle 100 of the handle 11 holding the LED display module box body 10, the LED display module is prevented from being in contact with the edge of the LED display module while the operability of the LED display module is improved, and the difficulty in installation and maintenance of the LED module is reduced.
In this embodiment, the handle 11 and the frame 12 are detachably connected, for example, the screw is used to connect the frame 12 and the handle 100 of the handle 11, which is advantageous in that when the handle 11 or the frame 12 is damaged or fails, the whole LED display module box 10 does not need to be scrapped, which is beneficial to reducing the maintenance cost of the LED module. In other embodiments, the handle 11 and the frame 12 may also be connected in a non-detachable manner, and the frame 12 and the handle 100 are connected in a riveting or welding manner, so that the LED display module box 10 has the advantages of better integrity and more stable structure.
