Aero base angle adjuster

Abstract

The invention relates to an aero base angle adjuster. The hydraulic cylinder comprises an outer cylinder barrel, a front connector, a gas spring assembly and a rear connector. The gas spring assemblycomprises an inner cylinder barrel arranged in the outer cylinder barrel. An auxiliary piston is arranged between the outer cylinder barrel and the inner cylinder barrel in a sliding manner; a first air cavity is formed between the inner cylinder barrel and the front joint; a main piston and an isolation piston are arranged in the inner cylinder barrel; the main piston and the isolation piston divide the interior of the inner cylinder barrel into a first oil cavity, a second oil cavity and a second air cavity. A piston rod is arranged in the center of the inner cylinder barrel, extends into the first oil cavity and is connected with a main piston in a matched mode, the main piston is in sliding fit with the inner wall of the inner cylinder barrel, an ejector rod is arranged in the piston rod, one end of the ejector rod extends into the front connector and is provided with a control switch, and the other end of the ejector rod penetrates through the main piston and is provided with a valve element opening and closing the second oil cavity. The angle-adjustable aero base is simple in structure and convenient to use, the angle of the aero base can be adjusted at will, good flight experience is brought to passengers, and the safety and comfort of the aero base are improved.

Description

technical field [0001] The invention relates to the technical field of aviation equipment, in particular to an aviation seat recliner. Background technique [0002] The recliner is a device used to adjust the angle of the seat back, which is widely used in automobiles, medical fitness equipment, building doors and windows, and aviation. [0003] At present, most of the adjustment devices on aviation seats use mechanical recliners, but the mechanical recliners have the disadvantage of poor stability, which often brings uncomfortable flight experience to passengers. Contents of the invention [0004] The technical problem to be solved by the invention is: in order to improve the stability of the adjustment device on the aviation seat. [0005] In order to achieve the above object, the present invention provides the following technical solutions: An aviation seat recliner provided by the present invention includes an outer cylinder, a front joint connected to the outer cylin...
