Abstract

The invention belongs to the technical field of aircraft structures and relates to a quickly-disassembled rotary opening cover lock. The quickly-disassembled rotary opening cover lock comprises a lock seat, a lock tongue, a special-shaped pin, a spring and a steel ball. The lock tongue is connected to the lock seat through the special-shaped pin. The steel ball and the squeezed spring are installed in an annular groove of the lock seat. One side of the steel ball abuts against a groove of the lock tongue, and the other side of the steel ball makes contact with the squeezed spring. According to the quickly-disassembled rotary opening cover lock, an opening cover can be quickly opened and locked, the size of a lock body is small, and meanwhile the damage to the structure of the opening cover is small; the quickly-disassembled rotary opening cover lock can be applied to aircraft bodies, missile pylons and other skin opening covers.

Description

technical field [0001] The invention belongs to the technical field of aircraft structures and relates to a quick-release rotary flap lock. Background technique [0002] The flap is an indispensable structural part of the aircraft, and flap locks are mostly installed on the flap to realize the quick opening and closing of the flap. At present, most of the flap locks are bulky, which is not conducive to installation on small flaps. At the same time, they need to be installed on the large opening of the flap, which damages the structural strength of the flap. At the same time, the opening and closing of the lid lock is jerky and laborious, which is not easy to operate. Contents of the invention [0003] The object of the present invention is to provide a quick-release rotary flap lock, which is simple in structure and easy to use, and is convenient to use on small-sized flaps. [0004] The technical solution of the present invention is: a quick-release rotary flap lock, co...
