The invention discloses a computer hard-disk quick-mounting shock-absorbing support frame, and mainly relates to the technical field of computers. The support frame includes a support plate. Each of aleft end and a right end of the top of the support plate is provided with a vertical connection plate. One side of the vertical connection plate away from the support plate is provided with a mounting brace frame. A horizontal support frame is disposed between the two vertical connection plates. Each of a left end and a right end of the top of the horizontal support frame is provided with a hard-disk mounting plate. Each of a left side and a right side of the horizontal support frame is provided with a first U-shaped chute. One end of the first U-shaped chute away from the horizontal supportframe is provided horizontally with a plurality of brace shafts. Second elastic columns are disposed on the brace shafts. One side which is of the vertical connection plate and is adjacent to the first U-shaped chute is provided with a second U-shaped chute. The computer hard-disk quick-mounting shock-absorbing support frame of the invention has the advantages that quick dismounting and mounting of a hard disk can be carried out, various vibrations and impacts on the computer hard-disk can be buffered, and resonance between the computer hard-disk and a case can be alleviated.
