Description

Technical Field

[0001] This utility model relates to the field of locking device technology, specifically a quick locking device. Background Technology

[0002] Airborne equipment in the aviation field generally adopts a modular chassis structure. The chassis is fixed in the corresponding equipment compartment. In order to give it a certain impact and vibration resistance, it is often reinforced by corresponding components. Locking devices are currently the most commonly used components for fixing airborne equipment chassis.

[0003] A current publication number CN103062169B discloses an anti-loosening locking device for aviation. This locking device includes a hinge seat, a connecting rod, and a length adjustment mechanism. The length adjustment mechanism includes a knob housing and a ring. The knob housing is threaded onto the connecting rod, and the ring is fitted onto the connecting rod and can move back and forth on the connecting rod. The knob housing and the ring are assembled together to prevent detachment. A floating washer that can float back and forth is mounted on the connecting rod to prevent rotation. An elastic pushing member is mounted between the ring and the floating washer. The knob housing has a tripping structure. The floating washer has anti-loosening teeth arranged on the side facing the tripping structure, forming an end face toothed ring. Taking the rotation direction of the knob housing when it moves backward on the connecting rod as the screw-in direction, the slope of the front tooth of the two teeth of the anti-loosening tooth in the rotation direction of the knob housing is greater than the slope of the other.

[0004] While existing technologies can achieve the locking function, they are cumbersome to use and have relatively poor shock resistance. Therefore, we propose a quick locking device. Utility Model Content
