Embodiment
A movable rack, comprises the first support 1001, the second support 1002, the three supports 1004, folding support body, tube shaped electric machine 1009, audio amplifier net 2003, backboard 2006.
Folding support body comprises base plate 1005 and fan-shaped side plate 1003.
Ceiling 1007 is arranged to construction opening, and the size of its construction opening is with suitable for placing the size of base plate 1005 of audio amplifier 1006.Base plate 1005 is embedded in construction opening, forms same planes with ceiling 1007, and its medial surface is audio amplifier 1006 fixedly, and lateral surface requires to design different pattern according to decorating, and mates guaranteeing with the decoration of ceiling.
Two blocks of fan-shaped side plates 1003 are fixed on the inner surface of base plate 1005, and in the direction of pivotal axis toward each other.
Central area on described fan-shaped side plate 1003 is provided with for the fixedly perforate 2002 of audio amplifier 1006, near base plate folding one side, is provided with for the perforate 2005 of audio amplifier net 2003 is installed.
On described fan-shaped side plate 1003, be also provided with the fan-shaped side plate suspension centre perforate 2001 of multi-angle, tube shaped electric machine 1009 is connected with fan-shaped side plate suspension centre perforate 2001 by steel wire rope 1008, to drive base plate 1005 to open or close construction opening under the control of control system, and then the relative ceiling of audio amplifier that makes to be installed on fan-shaped side plate 1003 exposes or is hidden in ceiling.According to different stage requests, select the fan-shaped side plate suspension centre perforate 2001 of different angles, make audio amplifier 1006 in use reach best stage effect.
