Description

Technical Field

[0001] The invention relates to the technical field of electric reflection devices, and in particular to a double-wing electric reflection device on the ceiling of a function hall. Background Art

[0002] Multi-functional halls are characterized by their diverse functions (such as concert halls, conference halls, theaters, and studios). These multi-functional halls all have audio-visual functions for viewing and performing, and have two spaces, a stage and an auditorium. Different uses have different requirements for sound and light effects. The sound and light of existing multi-functional halls are fixed, which makes the sound and light reflection range of the multi-functional halls relatively limited. CN110425495A discloses a multi-functional movable reflector, which starts to retract and release the traction rope through an electric wire retractor. The traction rope is connected to the upper end of the arc-shaped reflector through a fixed pulley, and the bottom of the arc-shaped reflector is clamped on the lamp mounting plate. When the traction rope starts to retract and release, it drives the arc-shaped reflector to rotate, thereby controlling the angle of the arc-shaped reflector, and realizing the lifting and opening and closing operations of the reflector by wireless remote control. However, existing multi-functional halls such as these cannot achieve the best use effect in different uses, and the lighting range of the multi-functional hall cannot be adjusted, which cannot meet the sound and light requirements of the multi-functional hall.

One end of the limiting plate is connected to the supporting balancing end, and the end of the supporting balancing end away from the limiting plate is connected to the active balancing stretching end.

[0010] Preferably, the length of the supporting balancing end is greater than that of the active balancing stretching end.

[0011] Preferably, the other end of the hinge of the limiting plate is fixedly connected to a telescopic lighting part, and the telescopic lighting part includes a lamp pole, a telescopic spring is sleeved on the lamp pole, and the other end of the telescopic spring is connected to an elastic telescopic hook, and the elastic telescopic hook is clamped with the performance light.

[0012] Preferably, the upper end of the automatic balancing part is connected to the steel belt through a steel belt clamp, the end of the steel belt away from the steel belt clamp is wrapped around the corner wheel and extends forward to be connected to the belt pulley, and the wheel axle of the belt pulley is connected to the hoist transmission through a coupling.

[0013] The above structure has the following beneficial effects:

[0014] The present invention drives the lead screw up and down through a spiral lifting mechanism, and the lead screw drives the sound reflecting plate to expand or fold, thereby changing the sound reflection range of the multi-function hall, thereby changing the reverberation time of the sound field of the multi-function hall.
