An electro pneumatic composite transmission structure and a cantilever beam structure

Abstract

The utility model relates to a kind of pneumatic-electricity composite transmission structure and cantilever beam structure, pneumatic-electricity composite transmission structure includes air pipe and telescopic outer tube.Flattened flexible circuit is laid on telescopic outer tube, air pipe is telescopically arranged in telescopic outer tube.Cantilever beam structure includes above-mentioned pneumatic-electricity composite transmission structure, two or more chain links, winding column and warehouse body.The utility model's pneumatic-electricity composite transmission structure is combined by air pipe and telescopic outer tube integrated with flattened flexible circuit, realizes the integrated synchronous telescoping of gas circuit and circuit, improves integration level and space utilization, applicable to the scene that gas and electric signal need to be transmitted synchronously and exist telescoping demand, such as cantilever beam structure.The structure design effectively reduces overall volume, is convenient for use and storage, and reduces the friction between components by various isolation and support design, guarantees transmission reliability.
