## Title
Adaptation device for hard disk drive

## Abstract

An adaptation device includes a lower casing member including a connection interface and forming a bottom slot in a front bottom, at least one retention flange on side walls, and pivot receiving holes in rear portions of the side walls. A retention board forms a connection interface receiving opening in a front end, rotation shafts on a rear end, and pawls on a bottom. The shafts are movably received in shaft slots defined in a rotary board. Pivots are formed below the shaft slots for being received in pivot receiving holes defined in the lower casing member. The rotary board has a hold-down plate. With a hard disk drive placed on the retention board and connected to a connection interface, the cover and the rotary board are closed forward to have the hold-down plate holding down the hard disk drive. The cover is then moved backward for fixation.

## Background
(a) TECHNICAL FIELD OF THE INVENTION
The present invention generally relates to an adaptation device for a hard disk drive, wherein the hard disk drive is positioned on a retention board and is fixed by a resilient hold-down plate and is further connected to a connection interface, so as to firmly hold the hard disk drive between a lower casing member and a cover, whereby efficient connection and mounting/dismounting of hard disk drives of various sizes can be realized.
(b) DESCRIPTION OF THE PRIOR ART
To cope with fast processing of digital data and exchange of information, a desktop computer or a notebook computer uses a hard disk drive, which may require frequent connection and mounting/dismounting. Particularly, the hard disk drive of the desktop computer or notebook computer is housed inside a computer enclosure and different computers use hard disk drives of different sizes. To perform mass data exchange, elaborated and complicated operations have to be carried out for connecting and mounting/dismounting of the hard disk drives. This is not only troublesome to the operation of data exchange but also consumes valuable time. It is thus desired to have a fixation structure that allows for efficient mounting/dismounting and is applicable to hard disk drives of different sizes.
SUMMARY OF THE INVENTION
In view of the above problems, the present invention aims to provide an adaptation device for a hard disk drive, which allows for efficient mounting/dismounting of the hard disk drive and is applicable to hard disk drives of different sizes in order to improve operation efficiency.
In accordance with the present invention, an adaptation device is provided for a hard disk drive, wherein a retention board that forms a connection interface receiving opening is fixed by engaging bottom slots defined in a lower casing member. Rotation shafts formed on a rear end of the retention board are slidably and rotatably received in extended shaft slots defined in a rotary board. A cover forms rotary board slide rails to slidably receive side edges of a rotary board. When a hard disk drive of a different size is placed on the retention board and is connected to a connection interface provided on the lower casing member, the cover and the rotary board are closed forward to have a hold-down plate arranged on the rotary board holding down a top of the hard disk drive. The cover is then moved backward to engage and thus be fixed under retention flanges formed on the lower casing member. In this way, the hard disk drive can be connected efficiently. The present invention simplifies the elaborate and complicated process of replacing a hard disk drive and thus improving the operation efficiency.
The foregoing objective and summary provide only a brief introduction to the present invention. To fully appreciate these and other objects of the present invention as well as the invention itself, all of which will become apparent to those skilled in the art, the following detailed description of the invention and the claims should be read in conjunction with the accompanying drawings. Throughout the specification and drawings identical reference numerals refer to identical or similar parts.
Many other advantages and features of the present invention will become manifest to those versed in the art upon making reference to the detailed description and the accompanying sheets of drawings in which a preferred structural embodiment incorporating the principles of the present invention is shown by way of illustrative example.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The following descriptions are exemplary embodiments only, and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims.
The present invention provides an adaptation device for a hard disk drive. As shown in FIGS. 1-3, the adaptation device comprises a lower casing member 1, a cover 2, a retention board 3, a rotary board 4, and the hard disk drive 5.
As shown in FIGS. 1-4, positional relationship among the components of the adaptation device will be described in details. The lower casing member 1 comprises a connection interface 30 and forms a bottom slot 12 in a front portion of a bottom thereof, at least one retention flange on side walls thereof, and pivot receiving holes 14 in rear portions of the side walls. The retention board 3 forms a connection interface receiving opening 31 in a front end thereof, rotation shafts 33 on a rear end, and pawls 32 on a bottom thereof. The rotation shafts 33 are slidably and rotatably received in extended shaft slots 41 defined in the rotary board 4. Pivots 42 are formed below the shaft slots 41 for being rotatably received in the pivot receiving holes 14 defined in the lower casing member 1. The rotary board 4 comprises a hold-down plate 40. The cover 2 forms rotary board slide rails 22 that cooperate the rotary board 4 to allow the cover 2 and the rotary board 4 to be closed forward through the rotation shafts 33 and the pivots 42 cooperating with the shaft slots 41.
Referring to FIGS. 3 and 4, the present invention mounts a Serial ATA (SATA) interfaced 2.5 inch or 3.5 inch hard disk drive 5 on the retention board 3 with the hard disk drive 5 connected to the connection interface 30. When the cover 2 and the rotary board 4 are closed forward, a hold-down plate 40, which is composed of a resilient member, holds down a top of the hard disk drive 5. The cover 2, after being set projecting forward through the rotary board slide rails 22 cooperating the rotary board 4, can moved backward to have cover slide rails 21 engaging and fixed under the retention flanges 13 of the lower casing member 1. To replace the hard disk drive 5, the cover 2 is moved forward to have the cover slide rails 21 disengaging from the retention flanges 13 for exposing and replacing the hard disk drive 5. This provides efficient connection and mounting/dismounting of hard disk drives of various sizes.
While certain novel features of this invention have been shown and described and are pointed out in the annexed claim, it is not intended to be limited to the details above, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the spirit of the present invention.
