In order to illustrate the technical features of the present solution clearly, the present application is described in detail hereinafter with reference to the specific embodiments and the drawings. The following disclosure provides a number of different embodiments or examples for implementing different structures of the present disclosure. In order to simplify the disclosure of the present application, components and arrangement of specific examples are described below. Besides, same reference numerals and/or letters are used in different examples of the present application. This repetition is for simplicity and clarity, which does not indicate a relationship between the various embodiments and/or arrangements described. It should be noted that the components shown in the drawings are not necessarily drawn to scale. The description of the known components and processing techniques and processes is omitted to avoid unnecessary restrictions on the present application.
The fixing bracket 1 has an L-shaped sheet metal structure, a horizontal plane of the L-shaped sheet metal is provided with a first blind rivet 11 for being fixed to a base of the case 5 by riveting, and a vertical plane thereof is provided with a second blind rivet 12 for being fixed to a side wall of the case 5 or an adjacent fixing bracket 1 by riveting. First positioning posts 13 are riveted on the vertical plane. The first positioning posts 13 face toward the elastic support member 2. When the hard disk is installed, the first positioning posts 13 are inserted into screw holes 41 on a side of the hard disk 4 to limit and fix the hard disk 4.
The elastic support member 2 includes two auxiliary brackets 21, two elastic-piece brackets 22 and a sheet metal handle 23. Both the two elastic-piece brackets 22 are arranged between the two auxiliary brackets 21. The sheet metal handle 23 is installed on one auxiliary bracket 21, and the sheet metal handle 23 can be pressed between the two elastic-piece brackets 22. The sheet metal handle 23 is fixed to the auxiliary bracket 21 through a blind rivet, which allows the sheet metal handle 23 to rotate around an axis of the blind rivet. The sheet metal handle 23 can be pressed between the two elastic-piece brackets 22, so that both the left and right elastic-piece brackets 22 are deformed at the same time, and the deformation enlarges the distance between the left and right elastic-piece brackets 22, while the distance between the elastic-piece bracket 22 and the fixing bracket 1 on the corresponding side is reduced, thereby clamping and fixing the hard disk 4. The positioning and fixing of the hard disk are realized by the fixing bracket 1 and the first positioning posts 13 on the elastic-piece bracket 22 located on a same side. The auxiliary bracket 21 is provided with a bending wall 211 for supporting the hard disk. A third blind rivet 212 for connecting with the base of the case 5 is provided on a horizontal plane of the auxiliary bracket 21, and a fourth blind rivet 213 for connecting with the elastic-piece bracket 22 is provided on the vertical plane. The elastic-piece bracket 22 is an L-shaped stainless steel sheet metal with a pre-folded structure. A fifth blind rivet 221 for riveting and fixing with the base of the chasses is installed on the horizontal plane of the L-shaped stainless steel sheet metal, and second positioning posts 222 are riveted on the vertical plane of the L-shaped stainless steel sheet metal, and the second positioning posts 222 face toward the fixing bracket 1. After the hard disk is installed, the second positioning posts 222 are inserted into the screw holes 41 on the other side of the hard disk 4. The vertical plane of the elastic-piece bracket 22 is angled relative to the horizontal plane and not perpendicular to the horizontal plane, and has a pre-bending deformation with a certain angle and is inclined to the elastic-piece bracket on the opposite side. A semi-rolled circle structure 223 is provided on the vertical plane of the elastic-piece bracket 22 to reduce the resistance when the semi-rolled circle structure is in contact with the sheet metal handle 23, so that the sheet metal handle 23 can be smoothly pressed and lifted. The sheet metal handle 23 has a sheet metal structure which is folded flat, and a bump 231 is arranged on the sheet metal handle 23. When the sheet metal handle 23 is pressed down, the bump 231 is squeezed between the two elastic-piece brackets 22, so that the elastic-piece brackets are deformed toward the auxiliary brackets 21 on the corresponding side, respectively. A support wall 232 is provided on the sheet metal handle 23 to be in contact with and be supported by the base of the case 5. Shock absorbing rubber sheets 3 are bonded to the fixing brackets 1, the auxiliary brackets 21 and the elastic-piece brackets 22 to reduce the influence of external vibrations on the hard disk.
The hard disk 4 can be installed and fixed by the device for fixing a hard disk in the following ways:
When installing multiple hard disks 4, first the sheet metal handle 23 is lifted, two hard disks 4 are loaded in turn, and then the sheet metal handle 23 is pressed down. At this time, the elastic-piece bracket 22 is deformed toward the hard disk 4 on the same side, and the first positioning posts 13 are inserted into the screw holes 41 on one side of the hard disk 4 for fixing and installing the hard disk. Other hard disks can be similarly installed in sequence.
When installing a single hard disk 4, first one side of the hard disk 4 is hooked to the fixing bracket 1, and then the hard disk 4 is pressed down and the other side of the hard disk is hooked to the elastic-piece bracket 22. The shock absorbing rubber sheets 3 bonded on the fixing bracket 1, the auxiliary bracket 21 and the elastic-piece bracket 22 are attached to a bottom or sides of the hard disk 4 to provide a shock absorbing effect. When the sheet metal handle 23 is pressed down into place, the case 5 is covered by an upper cover, and the sheet metal handle 23 is attached to the upper cover to prevent the sheet metal handle 23 from bouncing.
The specific embodiment of the present application is described with reference to the drawings, but it is not intended to limit the scope of the present application. On the basis of the technical solutions of the present application, various modifications or variations that can be made by those skilled in the art without any creative effort are still within the scope of the present application.
