Electric stage opening and closing device

Abstract

The invention discloses an electric stage opening and closing device which comprises a mounting plate, two symmetrical supporting plates are fixedly connected to the lower surface of the mounting plate, a driving motor is fixedly mounted on the lower surface of the mounting plate, a rotating shaft is fixedly connected to the output end of the driving motor, and a curtain is wound on the outer surface of the rotating shaft. A bottom plate is fixedly connected to the right side face of the supporting plate on the right side, a lead screw is rotationally connected to the upper surface of the bottom plate through a bearing, a nut seat is in threaded connection with the outer surface of the lead screw, a lifting plate is connected to the left side face of the nut seat through a limiting block, and the curtain is fixedly connected with the lifting plate. The lower surface of the mounting plate is connected with an arc-shaped cleaning plate through a telescopic rod and an extrusion spring, the arc-shaped cleaning plate is tightly attached to the curtain, through the arrangement of a series of structures, the device can prevent the position of the curtain from shifting when the curtain is opened and closed, meanwhile, the surface of the curtain can be cleaned, and the effect of removing dust and insects is achieved.

Description

technical field [0001] The invention relates to the technical field of stage curtains, in particular to an electric stage opening and closing device. Background technique [0002] The stage is the space provided for actors to perform in the theater, which can make the audience's attention focus on the actor's performance and obtain the ideal viewing effect. The stage usually consists of one or more platforms, some of which can be raised and lowered. The types of stage include mirror frame stage, extended stage, circular stage and rotating stage. The stage is generally equipped with a curtain for easy display. The curtain can be opened or closed by raising and lowering. [0003] Most of the opening and closing devices in the prior art adopt the "slide rail type". After a long time of use, due to the existence of errors, there will be an offset between the curtain and the transmission shaft, resulting in a lateral offset when the curtain is closed, and After the curtain is u...

Problems solved by technology

[0003] Most of the opening and closing devices in the prior art adopt the "slide rail type". After a long time of use, due to the existence of errors, there will be an offset between the curtain and the transmission shaft, resulting in a lateral offset when the curtain is closed, and After the curtain is used for a long time in summer, mosquitoes will remain on the surface of the curtain. If it is not cleaned in time, it will easily make the curtain dirty and difficult to clean. For this reason, we provide a stage electric opening and closing device
