The invention belongs to the field of aircraft structure design, and particularly relates to a self-adaptive bolt lock support structure. According to the structure, a movable support is fixedly installed on a cabin door, a first connector is arranged on the movable support, an installation hole is formed in the first connector, and a joint bearing is installed in the installation hole; the limiting stop piece is fixedly connected with the movable support and is provided with a first limiting part and a second limiting part, the deflection angle of the inner ring of the knuckle bearing is limited through the first limiting part, and the outer ring of the knuckle bearing is limited through the second limiting part; the fixed support is fixedly installed on the machine body, a second connector is arranged on the fixed support, a plug pin hole is formed in the second connector, and when the cabin door is closed, the plug pin hole is aligned to the bearing hole of the knuckle bearing; and the bolt penetrates through the bearing hole of the knuckle bearing and the bolt hole to finish locking. The limiting blocking pieces are installed on the two sides of the movable support, the knuckle bearing can be prevented from being disengaged when the plug pin is inserted, and the situation that the deflection angle of the knuckle bearing is too large to block the plug pin hole is prevented.

    本申请属于飞机结构设计领域,特别涉及一种自适应的插销锁支座结构。结构包括:活动支座固定安装在舱门上,活动支座上设置有第一接头,第一接头上开设有安装孔,安装孔中安装有关节轴承;限位挡件与活动支座固定连接,限位挡件具有第一限位部以及第二限位部,通过第一限位部对关节轴承内圈的偏转角度进行限位,通过第二限位部对关节轴承外圈进行限位;固定支座固定安装在机身上,固定支座上设置有第二接头,第二接头上开设有插销孔,在舱门关闭时,插销孔与关节轴承轴承孔对齐;插销穿过关节轴承轴承孔以及插销孔,完成上锁。本申请在活动支座两侧均安装有限位挡件,能够防止关节轴承在插销插入时脱出,防止关节轴承偏转角度过大反而堵住插销孔。
