Document Type and Number:
WIPO Patent Application WO/2021/083152
Kind Code:
A1
Abstract:
Disclosed are a quick-release structure and an aircraft. The quick-release structure comprises a first member; a second member, with one of the first member and the second member being provided with a protrusion (151), and the other being provided with a rabbet (231), the protrusion (151) being inserted into or disengaged from the rabbet (231) in a first direction such that the first member and the second member are assembled or disassembled; and a lock mechanism (3), which is arranged on the second member and can be selectively inserted into the first member in an insertion direction, with the insertion direction forming an included angle with the first direction. By means of inserting the lock mechanism (3) into a propeller (1) and inserting the protrusion (151) on the propeller (1) into the rabbet (231) in the first direction, the movement of a protection cover (2) relative to the propeller (1) in six directions is limited, achieving rapid installation of the protection cover (2). When the protective cover (2) needs to be disassembled, the lock mechanism (3) is disengaged from the propeller, and the protrusion (151) is disengaged from the rabbet (231) in a direction opposite to the first direction, achieving rapid release of the protective cover (2).
