The invention relates to a guiding and restraining structure suitable for a zero-gravity environment. The guiding and restraining structure comprises a limiting and restraining assembly and a positioning bush. The limiting and restraining assembly comprises an oblique cone guide frame and a limiting reed; the oblique cone guide frame is a transversely-arranged U-shaped frame, and a cone-shaped guide opening is formed in the U-shaped frame. Height guide limiting surfaces are arranged on the inner walls of the 'L'-shaped parts on the two sides of the U-shaped frame; the limiting reed is a U-shaped piece, and the two sides of the U-shaped piece are each provided with a semicircular protrusion. The middle of the positioning bush is of a hollow columnar structure, the upper portion and the lower portion of the hollow columnar structure are both of annular structures, the two opposite sides of the outer edge of the annular structure on the upper portion are flattened, two symmetrical vertical grooves are machined in the outer wall of the hollow columnar structure, and the grooves are matched with the semicircular protrusions of the limiting reed in size. And the grooves and the corresponding flattening parts are positioned on the same side. According to the invention, the technical problem that an astronaut cannot realize rapid and reliable connection and separation of two operation objects in an extravehicular environment is solved.

    本发明涉及一种适用无重力环境的导向约束结构,包括限位约束组件和定位衬套;限位约束组件包括斜锥导向架和限位簧片;斜锥导向架为横置的U型架,U型架形成锥状导向口;U型架两侧“|”部内壁上设置有高度导向限位面;限位簧片为U型片,U型片两侧“|”部各设计一个半圆凸起;定位衬套中部为空心柱状结构,空心柱状结构的上方和下方均为圆环状结构,上方圆环状结构外缘相对的两侧削平,空心柱状结构外壁上加工有两个对称的垂向凹槽,所述凹槽与限位簧片的半圆凸起尺寸匹配,且所述凹槽与对应的削平部位位于同一侧。本发明解决航天员在舱外环境中实现2个操作对象的快速可靠连接和分离的技术难题。
