[embodiment]

In order further to understand feature of the present utility model and technology contents, with reference to the accompanying drawings the utility model is described in detail.

With reference to Fig. 1, Fig. 2 and shown in Figure 3, the utility model comprises at least two LED screen unit 10, each LED screen unit 10 comprises fixed support 18, be installed in many LED luminotrons 16 on the fixed support 18 and be fixed on controller 20 on the LED luminotron 16, described one group of opposite side in each LED screen unit 10 is equipped with a pair of holder 70 at least, and the holder 70 of the described LED of being installed in screen unit 10 is articulated and connected by pivot arm 60 with the holder 70 that is installed in another LED screen unit 10.

With reference to Fig. 2, Fig. 4 and shown in Figure 5, the utility model holder 70 is installed in one group of opposite side of each LED screen unit 10, the one group of opposite side that is preferably in each LED screen unit 10 is installed two pairs of holders 70, being installed in the holder 70 of LED screen unit 10 and the holder 70 that is installed on another LED screen unit 10 is articulated and connected by pivot arm 60, holder 70 that another opposite side of above-mentioned another LED screen unit 10 is installed and the holder of installing on the LED screen unit 10 again 70 are articulated and connected by pivot arm 60, and formation single-string LED display screen 100 by that analogy is articulated and connected between described each LED screen unit 10.Described pivot arm 60 adopts metal material to make, and the both sides panel of pivot arm 60 is provided with a pair of pilot hole 701 and a pair of arc chute 62, turns up a pair of plate washer 66 at the side of pivot arm 60, and described plate washer 66 plays the effect of location.Holder 70 is fixed on by screw 703 on the pilot hole 701 of pivot arm 60 settings, and it is sealed with holder 70 to pass the arc chute 62 that is provided with on the pivot arm 60 with another screw 702 again.Wherein, pilot hole 701 by screw 703 with pivot arm 60 and holder 70 sealed after, the screw 703 that passes pilot hole 701 has played the effect of locating shaft with respect to holder 70; And pass the effect that arc chute 62 plays pivot arm 60 and holder 70 after sealed the location by screw 702.Wherein, LED screen unit 10 and another LED screen unit 10 by pivot arm 60 hinged after, be shown in the accompanying drawing 4 after opening fully between each LED screen unit 10, i.e. the configuration state of pivot arm 60 and holder 70; Be shown in the accompanying drawing 5 after folding between each LED screen unit 10, i.e. the configuration state of pivot arm 60 and holder 70.One group of opposite side of LED screen unit 10 a stationary installation wherein is installed on one side at least, described stationary installation can be fixing link 50.The design adopts and at the top of single-string LED display screen 100 two fixedly links 50 to be set, and three or even more fixing link 50 can be set as required.The design does not get rid of and adopts other frame mode to replace the fixedly effect of link 50, and such as the top at single-string LED display screen 100 fixed card slot being set also can (not shown in the accompanying drawing).
