DETAILED DESCRIPTION OF THE INVENTION

The present invention is described in further detail with reference to the attached drawings and the specific embodiments.

FIG. 1 shows a display screen in a specific embodiment of the present invention. The display screen comprises an LED lamp, a module 1 including related units, a fixed framework 2 consisting of a metal frame 21, pull rods 22, a reinforcing plate 23 and fasteners 24, and a power distribution control box 3 including a drive power 31, a metal housing 32, a receiving card 33, a rubber ring 34, quick connectors 35, etc. The module 1 and the power distribution control box 3 are installed on the framework 2. The framework 2 is smaller than the block in size.

As shown in FIG. 2, the module 1 is equipped with a high power LED lamp 12.

As shown in FIG. 3, the power distribution control box 3 consists of a metal bottom housing 321 and a metal upper cover 322. The bottom housing 321 is internally equipped with the drive power 31, and is equipped with a power supply signal transition plate 36 and a signal output plate 37 at two ends. The two ends of the bottom housing is equipped with a quick adaptor base 351 and a quick adaptor 352, and a waterproof rubber ring 38 are located between the bottom housing 321 and the upper cover 322. The upper cover 322 is internally equipped with an adaptor plate 39, and the receiving card 33 is fixed on the adaptor plate 39. The power supply signal transition plate 36 and the signal output plate 37 are equipped with a connector base 361. The adaptor plate 39 is equipped with an adaptor pin 391.

As shown in FIG. 4, the fixed framework 2 is used for installing the module 1 and the power distribution control box 3 and also used for connection between the display screen blocks and the suspended beam and connection between the blocks when the display screen is installed. The metal frame 21 of the fixed framework is equipped with two pull rods 22. One end of each of the pull rods 22 is a U-shaped groove and equipped with a slidable latch 25, while the other end is a plug matched with the U-shaped groove. The pull rods are equipped with two groups of fasteners 241 and fasteners 242 for different purposes. The fasteners 241 are used for horizontally connecting the blocks when the display screen is assembled into a panel. Slide fasteners are installed in a slide base and can be fastened with a wrench after being aligned with a fastener base. The fasteners 242 are used for horizontal connection when the display screen is assembled in an arch way. A pair of arc-shaped rings is respectively installed on an arc-shaped base, one equipped with a snap-fastener and the other equipped with a fastening pin. The arc between the two arc-shaped rings is not changed when the arc-shaped rings slide on the arc-shaped base. The pull rods are also equipped with a pair of rotary handles 26 for lifting the display screen blocks.

To assemble a panel-shaped display screen, align the U-shaped groove on the pull rod 22 with a plug or suspended beam of the pull rod 22 of a former display screen block, connect the two pull rods together with the plug, move the slide fastener to align slide fastener with the fastener base, pull the slide fastener to fasten the slide fastener along the arc-shaped groove of the fastener base. To assemble a shaped display screen, suspend the display screen block as mentioned above, loosen screws for fixing the arc-shaped rings before connecting the display screen blocks horizontally, adjust the distance between two arc-shaped rings to the optimal value, then fasten the screws for fixing the arc-shaped rings, and pull the snap-fastener to press the fastening pin.

The abovementioned is only a preferable embodiment of the present invention, which cannot limit the present invention. Within the technical spirit and principle of the present invention, subtle modifications, equivalent substitutions and improvements of the above embodiment all shall be incorporated in the protection scope of the present invention.
