[0002] The column light frame in the prior art cannot be adjusted according to the different performance forms or content of the play and the different width sizes of the stage entrance. When different plays need to be performed, the column light frame needs to be reinstalled in order to supplement the light source in the stage performance area and set off the performance atmosphere. Performances cannot be performed during the installation process. The whole process requires more manpower and material resources, which will reduce the practical performance of the entire column light frame and at the same time reduce the utilization rate of the theater.

[0003] On this basis, we propose a mobile column light stand for stage. Utility Model Content

A load-bearing guide wheel is hinged on the inner side of the connecting component, and a rubber roller is provided below the load-bearing guide wheel. A gap is left between the load-bearing guide wheel and the rubber roller. The guide rail is clamped in the gap between the load-bearing guide wheel and the rubber roller. The load-bearing guide wheel contacts the upper surface of the lower end of the guide rail, and the rubber roller contacts the lower surface of the lower end of the guide rail.

[0009] Furthermore, the guide rail is made of a whole I-beam material, the guide rail is fixed to an end plate provided below the steel structure, one side of the guide rail is welded to the end plate, and the other side of the guide rail is detachably connected to the end plate.

[0015] The rack and pinion transmission can withstand large loads and is suitable for use in mechanical equipment that needs to transmit heavy loads. Through the precise meshing of the gear and the rack, the rack and pinion transmission can achieve high-precision motion control and meet the high-precision requirements of engineering needs. This transmission method has small slippage, which can effectively reduce energy loss during the transmission process and improve transmission efficiency; by changing the speed ratio of the gear or rack, the rack and pinion transmission can achieve a wide range of speed adjustment, which is suitable for occasions that require rapid speed changes. Compared with other types of mechanical transmission, the maintenance of the rack and pinion transmission is relatively simple, and the service life can be extended by replacing worn parts.
