Quick release lock with spring device

Abstract

The invention discloses a quick release lock with a spring device. An upper lock body consists of a lock pin, a spring, a lock seat disk and a gasket; the lock seat disk and a lower lock seat are both provided with two side blades respectively and are also provided with installation holes; the lock seat disk is provided with a central through hole, a protruded circumferential ring surrounding thecentral through hole is arranged on two sides of the lock seat disk respectively, the spring is arranged and the lock pin is sleeved in the central through hole of the protruded circumferential ring;the spring is connected with a step of the lock pin; the other end of the spring is connected with a step in the central through hole; the gasket is arranged in a connection gap between the spring and the central through hole; the lower lock seat consists of a snap spring sheet and a lower lock body; the lower lock body is arranged in the snap spring sheet; and a through hole corresponding to theupper lock body is formed in the center of the snap spring sheet and the lower lock body respectively. The quick release lock can solve the problem that a large-curvature curved covering cap cannot be opened by a common quick release lock, and can also avoid the problem that the lock pin falls, and facilitates the daily using and maintenance of an airplane.

Description

technical field [0001] The invention relates to a lock structure, in particular to a quick-release lock with a spring device used on an aircraft hatch. Background technique [0002] There are many flaps for daily maintenance on various types of aircraft designed and manufactured in China in the past. The connections on them are usually HB2-46-76 small load-bearing locks. The small load-bearing locks are used on the flaps. It is relatively flat, but its disadvantage is that when the cover has a shape or the cover has a large curvature, the locking nail cannot be taken out, resulting in the failure of the small load-bearing lock and the cover cannot be opened. The use of this quick-release lock with a spring device can not only solve the problem that the large-curvature curved surface cover cannot be opened with a common quick-release lock, but also avoid the problem of the lock pin falling off, which facilitates the daily use and maintenance of the aircraft.
