Description:
BACKGROUND OF THE INVENTION 
       [0001]    a) Field of the Invention 
         [0002]    The present invention relates to a disk drive case which is used to hold a disk drive, and more particularly to a disk drive case which can be quickly inserted into or pulled out of a computer case, and by which the disk drive can be quickly positioned. 
         [0003]    b) Description of the Prior Art 
         [0004]    A removable disk case is first loaded with a disk drive (hard disk drive), and is then inserted into a device slot of a computer case. Usually, inside the device slot there will be provided with a corresponding connection port such that after the disk drive, along with the disk case, has been inserted, the disk drive will correspond to the position of the connection port, and connections of electricity and information are accomplished. In addition, the disk case is also provided with an ejection device, allowing the disk drive to separate with the connection port in the device slot only by an ejection action when the disk case is ejected. This disk case is a front-connection type that the device slot is usually at a front position of the computer case; whereas, the other type of removable disk case is a side-connection type and is applied inside the computer case. An insertion opening of the disk case is provided inside the computer case, and an opening end of the device slot is at a side of the computer case. This type of disk case is often used to assemble a built-in hard disk, and functions primarily to facilitate assembling the hard disk. The device slot fits primarily with a disk drive case, with a surface of the case being provided with a plurality of through-holes, such that after a disk drive has been placed on the surface of the case, screws are used to transfix the through-holes to lock the disk drive onto the surface of the case. Next, the entire disk drive case (including the disk drive) is inserted into the device slot, and is effectively fixed in the device slot. Although this kind of mechanism has been designed toward convenience, the fixing of the disk drive still requires locking elements (such as the screws) that the disk drive can be fixed effectively. Therefore, assistance with a tool is still required in disassembling and assembling. Accordingly, it is still inconvenient in a assembling, which still exists a significant space for improvement. 
       SUMMARY OF THE INVENTION 
       [0005]    Accordingly, the present invention is to provide a disk drive case which can be conveniently and quickly disassembled and assembled, so as to improve the conventional design. 
         [0006]    To achieve the aforementioned object, a disk drive case of the present invention is formed with a plurality of first axial positioning devices to rapidly position the disk drive, and a second axial positioning device which can effectively clamp the disk drive such that the disk drive is fixed completely. Accordingly, when installing the disk drive, the disk drive can be quickly fixed by two mutually perpendicular axial positioning devices, thereby achieving the object of disassembling and assembling conveniently and quickly. 
         [0007]    To enable a further understanding of the said objectives and the technological methods of the invention herein, the brief description of the drawings below is followed by the detailed description of the preferred embodiments.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0015]    Referring to  FIG. 1 , it shows a three-dimensional view of the present invention, wherein a disk drive case  10  comprises primarily a disk assembly part  101 , a surface of which is formed with a plurality of through-holes to increase a heat dissipation effect, and two sides of which are bended inward respectively to form a baffle wall  102 ,  102 ′, with surfaces of the two baffle walls  102 ,  102 ′ being protruded with a plurality of assembly parts  1021  that are provided respectively with a locking element  1022 . In addition, an end of the disk assembly part  101  (the end between two baffle walls  102 ,  102 ′) is bended to form a pulling part  103 , allowing an assembly person to exert force with fingers to facilitate disassembling or assembling. Furthermore, the surface of the disk assembly part  101  is protruded upward to form a plurality of first axial positioning devices  1011 , and one baffle wall  102 ′ is loosely pivoted with a second axial positioning device  104  which is in a shape of a cover board and a movable end of which, after covering, can be locked at the baffle wall  102 . 
         [0016]    Referring to  FIG. 2 , it shows a schematic view of components before being assembled, in accordance with the present invention. The baffle wall  102 ′ of the disk drive case  10  is formed with a pivoting part  1021 ′ which forms a movable pivoting relation after being transfixed with a corresponding pivoting part  1041  formed at one end of the second axial positioning device  104 . In other words, the second axial positioning device  104  can result in a corresponding open-close operation by the pivoting relation between the pivoting part  1021 ′ and the corresponding pivoting part  1041 . On the other hand, the second axial positioning device  104  includes a suppressing part  1042  and an engaging part  1043 ; these two parts are roughly perpendicular to each other or their included angle is a little smaller than 90°. Moreover, in order to allow the engaging part  1043  to effectively latch, a surface of the engaging part  1043  can be formed with a plurality of engaging teeth  1044 . As shown in the drawing again, on the baffle wall  102 , at locations corresponding to the engaging teeth  1044 , can be formed with engaging holes  1024  (or protruded ribs). Furthermore, to allow the second axial positioning device  104  to be tightly attached on a surface of the disk drive upon being fixed, a surface of the suppressing part  1042  is adhered with an elastic suppressing piece  1045 . Therefore, when the suppressing part  1042  suppresses the surface of the disk drive, the suppressing part  1042  can be tightly attached to the disk drive by the elasticity of the suppressing piece  1045 , allowing the disk drive to be effectively suppressed and fixed. As shown in the drawing once more, the locking element  1022  is made by a material having some elasticity and is fixed at the assembly part  1021  with a fixing element  1023 . The primary function of this locking element  1022  is to lock the disk drive case  10  at a locking part (not shown in the drawing) which is formed in a device slot, after inserting into the device slot. On the other hand, the first axial positioning devices  1011  that are formed on the surface of the disk assembly part  101  collaborate primarily with screw holes formed on the disk drive to limit the disk drive to the first axial positioning devices  1011  by using these screw holes. 
         [0017]    Referring to  FIG. 3 , it shows a first schematic view of an implementation of the present invention, wherein using the disk drive case  10  of the present invention, a disk drive  20  is quickly assembled in a computer. When implementing, a bottom part  201  of the disk drive  20  matches with the disk assembly part  101  of the disk drive case  10 , and each screw hole  202  which is formed at the bottom part  201  matches with each first axial positioning device  1011  on the surface of the disk assembly part  101 . Hence, the disk drive  20  can be positioned horizontally after being inserted into the disk assembly part  101 , due to that as each screw hole  202  has been already inserted with each first axial positioning device  1011 , the disk drive will not be able to displace along the horizontal direction. As shown in the drawing again, after placing the disk drive  20  (referring to a dotted line in the drawing), the second axial positioning device  104  is then covered, the engaging part  1043  at one end of the second axial positioning device  104  is engaged at the baffle wall  102  at the corresponding position, and the engaging teeth  1044  of the engaging part  1043  (referring to  FIG. 2 ) are latched into the engaging holes  1024  of the baffle wall  102 . After latching, the suppressing part  1042  of the second axial positioning device  104  can exactly suppress the disk drive  20  to accomplish a vertical positioning. Thereby, as the disk drive  20  has been completely positioned horizontally and vertically, it can be effectively assured that the disk drive  20  is fixed in the disk drive case  10 . Moreover, as shown in the drawing, in order to fix the disk drive  20  more tightly, the suppressing part  1042  can be adhered with the suppressing piece  1045  having some elasticity, enabling the suppressing part  1042  to suppress the surface of the disk drive  20  more tightly. 
         [0018]    Referring to  FIG. 4 , it shows a second schematic view of an implementation of the present invention. Following  FIG. 3 , after the disk drive  20  has been entirely fixed in the disk drive case  10 , the disk drive case  10  can be quickly inserted into a corresponding slot  301  of a computer host  30 . As shown in  FIG. 4 , the slot  301  is located at a side of the computer host  30 , and two sides of the slot  301  are formed with a corresponding slide rail  302 . When the disk drive case  10  is to be placed into the slot  301 , an end for insertion matches with the slide rails  302  and is then pushed in. Referring to  FIG. 5 , it shows a third schematic view of an implementation of the present invention. After one end of the disk drive case  10  has been placed into the slot  301 , the locking elements  1022  at two sides of the disk drive  10  will correspond to the slide rails  302  and slide from the slide rails  302  to tail ends  3022  of the slide rails  302  along inclined chutes  3021 . As the locking element  1022  is provided with some elasticity, it will be locked in a locking hole  3023  at the tail end  3022  of the slide rail  302 . Referring to  FIG. 6 , it shows a fourth schematic view of an implementation of the present invention. Following  FIG. 5 , the entire disk drive case  10  is pressed down next, enabling the other locking element  1022  to be locked at the other locking hole  3024  at a front end of the slide rail  302 , thereby accomplishing the quick assembly of the entire disk drive case  10  and the disk drive  20 . On the other hand, upon disassembling, the front end of the disk drive case  10  is pushed upward first, and then the entire disk drive case  10  is pulled out, thereby accomplishing the disassembly operation. 
         [0019]    Referring to  FIG. 7 , it shows a schematic view of another preferred embodiment of the present invention, wherein the locking element  1022  can also match with another kind of slide rail with an inner slot. For example, as shown in the drawing, a slide rail  40  is a slide rail with an inner slot. The locking element  1022  can be pushed into the slide rail  40 , and the remaining operations are the same as those disclosed in  FIG. 4  and  FIG. 6 . 
         [0020]    Accordingly, the disk drive case  10  of the present invention primarily provides the first axial positioning devices  1011  to fix the disk drive  20  horizontally, and the second axial positioning device  104  (as shown in  FIG. 1 ) to fix the disk drive  20  vertically. Thereby, the disk drive  20  can be fixed quickly and effectively, and can be quickly inserted into or pulled out of the slot in the computer host by using the plural locking elements  1022  at the sides of the disk drive case  10 . Accordingly, after implementing the disk drive case of the present invention, the object of providing a disk drive case that can be disassembled and assembled conveniently and quickly is actually achieved. 
         [0021]    It is of course to be understood that the embodiments described herein is merely illustrative of the principles of the invention and that a wide variety of modifications thereto may be effected by persons skilled in the art without departing from the spirit and scope of the invention as set forth in the following claims.
