Outer-lining aero seat chair tube

Abstract

The invention discloses an outer-lining aero seat chair tube. The chair tube comprises a chair tube body, the chair tube body is an even thin-wall long tube with a central hole in the middle, both ends of the chair tube body are provided with armrest support mounting bases, a plurality of composite mounting bases are arranged in the middle of the chair tube body, and the armrest support mounting bases and the composite mounting bases are connected with the chair tube body in a post-assembling mode, so that machining of the chair tube is more convenient, and it is only necessary to complete machining of two independent cylindrical parts; the chair tube is divided into two separate parts, in the condition that the strength of the chair tube is ensured, the weight of the chair tube is reduced as much as possible, and the stress of external assembly parts is borne by the mounting bases outside the long tube.

Description

technical field [0001] The invention relates to the field of aviation seats, in particular to an outer-lined aviation seat tube. Background technique [0002] The aviation seat tube is the main load-bearing tube of the aviation seat, on which are installed the main load-bearing parts, the chair legs and the armrest frame. Setting the liner pipe at the leg position increases the thickness value of this section. Due to the difficulty in processing the inner hole of the long pipe, the processing cost is high and the disassembly and assembly are inconvenient. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned problems in the prior art, and propose an outer-lined aviation seat chair tube, which sets the chair tube into two separate parts and minimizes its strength while ensuring its strength. weight and allow the stress of the external assembly to be borne by the mounts on the outside of the long tube. [0004] The purpo...
