Anti-dropping Device Connection Member Screw Rotation Prevention

The patent introduces a connection member as an intermediary component between the elastic member and the screw. The connection member includes a first hole for the anti-dropping boss and second holes for screws, with connecting parts linking them. This intermediary structure prevents the elastic member from rotating during installation while maintaining the anti-dropping function, as the connection member absorbs and distributes the rotational forces.

The patent segments the anti-dropping system into multiple components: the elastic member, the connection member with holes and connecting parts, and the anti-dropping boss. This segmentation distributes the mechanical stresses and prevents direct bending of the elastic member, as the connection member structure provides support and guidance for force distribution.

The patent merges the anti-dropping function with the connection structure by integrating the anti-dropping boss, connection member with holes, and connecting parts into a unified system. This combination eliminates the need for separate individual anti-dropping members, reducing design complexity while maintaining the anti-dropping function through the integrated structure.

The patent applies local quality by designing specific geometric features at critical locations: the first hole adapts to the cross-section of the anti-dropping boss, the second holes are positioned for screw insertion, and the connecting parts have specific shapes. These localized geometric optimizations ensure proper fit and function while preventing stuck or over-tightened situations through controlled clearance and engagement geometry.
