Description

Technical Field

[0001] The utility model mainly relates to the technical field of key protection, in particular to a self-resetting key protection cover. Background Art

[0002] At present, in the field of airborne defense, most products need to be used in a vibration environment. Various forms of key protection covers play a very important role in preventing operators from making mistakes and causing unnecessary consequences.

[0003] Considering human-machine efficiency and to facilitate key operation, the protective cover is designed to be self-resetting. That is, after applying external force to open the key cover, the external force is removed and the cover automatically closes. In the closed state, the keys cannot be touched, providing protection.

[0004] Conventional key protection covers use the friction of the rotating shaft to control the angle of the protection cover. In a vibration environment, the protection cover will open automatically and cannot prevent misoperation. This application makes up for the shortcomings of conventional key protection covers.
