Description

Hard drive holding device

The invention relates to a hard disk fixing device, in particular to a hard disk fixing device which provides multiple axial shock-proof effects.

Due to the advantages of repeated reading and writing, fast access, and large storage capacity, hard disk drives have recently become the most commonly used memory devices for computers and servers. For the purpose of protecting hard disks, hard disks in some higher-level computers and servers are equipped with anti-vibration structures that can absorb the vibration generated by the hard disk drive.

The conventional hard disk anti-vibration structure is to fix the anti-vibration washer on the fixing plate, and use a step screw to pass through the anti-vibration washer to lock the hard disk. When the hard disk drive is vibrated by external force, the shockproof effect is achieved by the cushioning force generated by the elastic material of the shockproof washer. However, the conventional hard disk anti-vibration structure can only provide better anti-vibration effects for a single axial direction due to the gap between the step screw and the inner edge of the anti-vibration washer, but cannot achieve multi-axial anti-vibration effects.

The step screws are respectively embedded in the inner edge and are in close contact with the inner edge. Each step screw includes a head and a screw shaft connected to the head. The step screw directly locks the hard disk drive.

In one embodiment, the material of the hollow bushing and the anti-vibration gasket is an elastic material.

In one embodiment, the diameter of each hollow bushing is the same as the diameter of the screw shaft of each step screw.

In one embodiment, the length of each hollow bushing is greater than the height of each of the fixing plate sleeve holes.
