The invention relates to an integral structure of a mooring joint and a jack support on an aircraft, which belongs to the field of aircraft structural design. A mooring joint and jack support structure on an aircraft includes connecting parts and rods; the connecting parts are arranged in the airframe, the top part of which is connected with the main bearing member of the airframe structure, and the bottom part of which is provided with a through hole I through which rods pass; a through hole II opposite to the through hole I is arranged on the skin of the airframe structure; one end of the rod member passes through through through through through through the through hole I, through hole II and connecting parts. Fixed, the other end is provided with a jack support matching the jack top, and a mooring hole is arranged on the rod body of the rod member to allow the mooring joint to pass through. Compared with the prior art, the present invention has the following advantages: 1. The connecting parts are arranged in the airframe, and only the connecting points are highlighted outside. While meeting the requirements of mooring joint and Jack support, the mooring cover is omitted and the influence on the aerodynamic shape of the airplane is reduced. 2. The function of tie-in joint and jack support is integrated, which reduces the arrangement of the joints on the body structure, reduces the weight of the body mechanism and reduces the assembly workload.

一种飞机上系留接头及千斤顶支座结构
本专利技术涉及一种飞机上系留接头及千斤顶支座一体式结构,属于飞机结构设计领域。
技术介绍
飞机上系留接头是飞机在长期或短期停放及运输过程中,将飞机与地面系留接头或车载装置通过系留索连接,保证飞机不被强风、雨水、海浪及运输过程中的振动、惯性等冲击而产生位移,确保飞机停放及运输过程的安全。千斤顶支座是固定在飞机上,提供千斤顶顶起飞机时所需的支撑点。现有飞机上的系留接头大多布置在前机身、起落架及飞机尾部,为了不影响气动外形,部分飞机会在机身上的系留接头处布置有系留口盖,且千斤顶支座与系留接头分开布置,浪费了重量,增加了装配的复杂度。
技术实现思路
本专利技术的目的是解决现有技术中存在的问题,提供一种重量轻、装配效率高,同时将系留接头与千斤顶支座二者的功能合为一体的飞机上系留接头及千斤顶支座结构。为了实现上述目的,本专利技术采用如下技术方案:一种飞机上系留接头及千斤顶支座结构,包括连接件、杆状件;所述连接件设置于机体内,其顶部与机体结构的主承力构件连接,其底部设置有容杆状件穿过的通孔Ⅰ;在机体结构的蒙皮上设置有与通孔Ⅰ相对的通孔Ⅱ;杆状件的一端穿过通孔Ⅰ、通孔Ⅱ与连接件固定,另一端设置有与千斤顶顶部匹配的千斤顶支座,在杆状件的杆体上设置有容系留接头穿过的系留孔。优选的,所述连接件为三角形框架,其中一面与机体结构的主承力构件外形适配;其余两面与机身外形适配,通孔Ⅰ设置于两面形成的夹角处。优选的,在两面形成的夹角处设置有凸台,凸台沿连接件的中心轴向上延伸,通孔Ⅰ沿凸台的轴向设置。优选的,所述通孔Ⅰ为阶梯状通孔,且顶部直径小于底部直径。优 ...
