The invention relates to a self-hidden folding lifting lug device in the technical field of flying object hanging and hoisting, which comprises a U-shaped lifting lug, a base with the bottom mounted in a cavity and a cavity wall plate corresponding to the outside of the top of the base, and a U-shaped notch is formed in the plate surface of the cavity wall plate; the U-shaped lifting lug comprises a top transverse section and two vertical supporting sections, the two vertical supporting sections are located in two longitudinal strip holes of the U-shaped notch respectively, the bottom ends of the vertical supporting sections are rotationally connected with the top of the base through rotating shafts, so that the U-shaped notch can be blocked after the U-shaped lifting lug rotates and lies down from an external hanging state, and the outer lug surface of the U-shaped lifting lug is aligned and consistent with the outer plate surface of the cavity wall plate; the rotating shaft is sleeved with a torsional spring, and two force arm sections of the torsional spring are connected with the U-shaped lifting lug and the base correspondingly, so that the U-shaped lifting lug has the lying tendency; the inner lug surface and the outer lug surface of the U-shaped lifting lug are inclined surfaces capable of mutually forming an included angle, and the rotating center of the rotating shaft deviates from an angle bisection surface of the included angle; the lifting lug device is more simplified, lighter and standardized, and meanwhile, the pneumatic shape is optimized.

    本发明涉及挂飞物吊装技术领域的一种自隐式折叠吊耳装置,包含U型吊耳、底部安装于腔体内的基座,以及对应于基座顶部外的腔壁板,腔壁板的板面设有U形缺孔;U型吊耳包含顶横段和两个立撑段,两个立撑段分别位于U形缺孔的两个纵条孔中,立撑段的底端通过转轴与基座顶部转动连接,以使得U型吊耳从外挂状态转动躺倒后能够封堵U形缺孔,且U型吊耳的外耳面与腔壁板外板面齐合一致;转轴套设有扭簧,扭簧的两个力臂段分别与U型吊耳和基座连接,以使得U型吊耳具有躺倒的趋势;U型吊耳的内耳面和外耳面均设为相互能够形成夹角的斜面,且转轴的转动中心偏离该夹角的角平分面;该吊耳装置更加简化、轻量化和标准化的同时,优化了气动外形。
