In concrete enforcement, be fixedly connected with connection platform 65 on this lower surface of this cylinder 61, this set collar 62 is fixedly connected on the bottom of this connection platform 65.
This locking pin 63 is fixedly connected on the bottom of this connection platform 65, and this locking pin 63 is arranged in this set collar 62.
This connects the diameter of platform 65 greater than the diameter of this cylinder 61.
In concrete the application, can enlarge the size of this set collar 62 by the structural design of this connection platform 65, thereby promote the strength of joint between this set collar 62 and this circuit board 52.
By above-mentioned structural design make that LED display of the present utility model can satisfy fully that people are clear to the superelevation of indoor LED display, requirement such as high brightness, height refresh.
For follow-up module maintenance maintenance, because this module part 10 is spliced by some these first splicing submodule groups 40, and this first splicing submodule group 40 is spliced by some these second splicing submodule groups 50, change so when the submodule group need be changed, corresponding module directly can be pulled down, can promote maintenance efficiency greatly.
Because the spacing of led light source of the present utility model is high and close, so on-site maintenance is relatively more difficult, have only 80*80 millimeter size so the utility model people designs every lamp plate in addition, can directly change module, lamp plate fully.
This casing part 20 is the die casting casing, requires the die casting of high precision high-flatness in the process of die casting, is respectively arranged with reference column 21 around the back side of this casing part 20.
Traditional casing has only reference column up and down, and movable reference column is arranged around the casing of the present utility model, can reach in the effect that guarantees not influence under the situation accurately splicing.
This reference column 21 is fixedly installed on the corner location at these casing part 20 back sides, and each this reference column 21 all has a pilot hole.
Be respectively arranged with connection snap close 22 around the back side of this casing part 20, make this casing part 20 when splicing each other by this connection snap close 22, the splicing relation safety is easy.
In addition, also be provided with flexible handle 23 on this connection snap close 22, thereby make these casing part 20 overall appearances and splice convenient and swiftly, people just do not need to add other at the scene in concrete use the instrument just can be realized splicing each other.
This back cover portion 30 snaps onto the back side of this casing part 20, is provided with some buckles 31 around these back cover portion 30 bottoms, and is corresponding at the corresponding draw-in groove 32 that offers in these casing part 20 back sides with this buckle 31.
Each this buckle 31 all snaps onto in this corresponding draw-in groove 32, thereby realizes being connected of this back cover portion 30 and this casing part 20.
In concrete enforcement, it is convenient to operation that these back cover portion 30 main functions are that components and parts such as storage case in-body power source signal wire use above-mentioned connected mode to have, and connection need not any screw, adopts the draw-in groove location, precisely characteristics conveniently.
In concrete enforcement, what the power supply connector on this back cover portion 30 adopted is the power connector of using on computers, thereby makes applicability of the present utility model and reliability that higher guarantee be arranged in addition.
