Device for fixing hard disk
A device with shock-absorbing qualities for fixing a hard disk in place on a chassis includes two brackets, a plurality of shock-absorbing cushions, and a plurality of first fasteners is described. The brackets located at opposite sides of a hard disk and the side surface of the bracket define a plurality of circular through holes with notches or cutaways continuing to the outer edge of the side surface. The cushions can be locked in the circular through holes after being introduced through the notches whilst sleeving the first fasteners. Two support portions are bent from ends of each bracket to support the hard disk in place.
1. A device configured to fix a hard disk to a chassis body, the device comprising:
a plurality of brackets configured to positioned two opposite sides of the hard disk, each of the brackets comprising a bottom surface and a side surface adjacent to the bottom surface, the side surface defining a plurality of circular through holes;
a plurality of cushions locked in the plurality of the circular through holes;
a plurality of first fasteners passing through the cushions to connect the brackets to the hard disk;
two support portions bending from two ends of each of the brackets; and
two abutting portions extending from the two support portions of each of the brackets and positioned below the bottom surface to be fixed to the chassis body.
2. The device of claim 1 , wherein the side surface further defines a plurality of notches, the plurality of notches extend to the plurality of circular through holes and an edge of the bracket.
3. The device of claim 1 , wherein an annular locking slot is defined on an circumferential surface of each of the cushions, the cushion is deformable, the bracket is locked in the annular locking slot.
4. The device of claim 3 , wherein the bracket is locked in the annular locking slot in a transitional fit.
5. The device of claim 1 , wherein each of the first fasteners comprises a shaft body and a protrusion protruding from an end of the shaft body, a surface of each of the protrusions adjacent to the shaft body abuts the cushion, an end of each of the shaft bodies away from the protrusion has an external thread and is screwed in one of threaded holes defined on the hard disk.
6. The device of claim 1 , wherein the two support portions on each of the brackets are located on a side of the bracket facing the hard disk.
7. The device of claim 6 , wherein the two abutting portions extending from the two abutting portions on each of the brackets are located between the two support portions of each of the brackets.
8. The device of claim 6 , wherein the two support portions of each of the brackets are located between the two abutting portions extending from the two support portions.
9. The device of claim 1 , wherein the device further comprises a plurality of second fasteners, each of the second fasteners passes though one of the abutting portions and is coupled to the chassis body.
10. The device of claim 1 , wherein the cushion is made of rubber.
11. A device configured to fix a hard disk to a chassis body, the device comprising:
a plurality of brackets parallel to each other and configured to positioned two sides of the hard disk, each of the brackets comprising a bottom surface and a side surface perpendicular to the bottom surface, the side surface defining a plurality of circular through holes;
a plurality of cushions locked in the plurality of the circular through holes;
a plurality of first fasteners, one end of each of the first fastener passing through one of the cushions to be fixed to the hard disk;
two support portions bending from two opposite ends of each of the brackets; and
two abutting portions extending from the two support portions of each of the brackets and positioned below the bottom surface to be fixed to the chassis body.
12. The device of claim 11 , wherein the side surface further defines a plurality of notches, the plurality of notches extend to the plurality of circular through holes and an edge of the bracket.
13. The device of claim 11 , wherein an annular locking slot is defined on an circumferential surface of each of the cushions, the cushion is deformable, the bracket is locked in the annular locking slot.
14. The device of claim 13 , wherein the bracket is locked in the annular locking slot in a transitional fit.
15. The device of claim 11 , wherein each of the first fasteners comprises a shaft body and a protrusion protruding from an end of the shaft body, a surface of each of the protrusions adjacent to the shaft body abuts the cushion, an end of each of the shaft bodies away from the protrusion has an external thread and is screwed in one of threaded holes defined on the hard disk.
16. The device of claim 11 , wherein the two support portions on each of the brackets are located on a side of the bracket facing the hard disk.
17. The device of claim 16 , wherein the two abutting portions extending from the two abutting portions on each of the brackets are located between the two support portions of each of the brackets.
18. The device of claim 16 , wherein the two support portions of each of the brackets are located between the two abutting portions extending from the two support portions.
19. The device of claim 11 , wherein the device further comprises a plurality of second fasteners, each of the second fasteners passes though one of the abutting portions and is coupled to the chassis body.
20. The device of claim 11 , wherein the cushion is made of rubber.
