Description

The fixed mechanism of Winchester disk drive

Technical field

The utility model relates to a kind of fixed mechanism, particularly a kind of Winchester disk drive fixed mechanism of using in the what computer chassis.

Background technology

The hardware device part of computer system is made up of equipment such as motherboard, various interface card, floppy drive, Winchester disk drive and CD player haply, and these equipment all are installed in the casing, and this casing is commonly referred to as computer chassis; Computer chassis has comprised that a housing and with accommodation space can seal the lid of accommodation space, optionally dispose by equipment such as what floppy drive, Winchester disk drive and CD player, therefore for facility on assembling and the continuous extendibility of Hou, usually in computer chassis, understand the frame of equipment such as pre-configured floppy drive, Winchester disk drive and CD player, so that day Hou user can or expand equipment such as floppy drive, Winchester disk drive and CD player by these frame dismounting.

And at present the fixed form of disk drive to adopt screw that it is locked mostly fixing, just earlier disk drive is inserted in the mounted frame, utilize screw with disk drive fixedly on the what frame, again to reach the assembling purpose that disk drive is fixed on computer chassis.Strict, this kind fixed form has some shortcomings, and for example: when the assembling disk drive, the product line worker must over and over again employ the action that turnscrew is locked.Its production routine is complicated and loaded down with trivial details, is difficult to promote efficient.

Summary of the invention

The purpose of this utility model is to provide a kind of fixed mechanism of Winchester disk drive, enables free-handly under the situation that need not employ turnscrew to finish Winchester disk drive fixing in computer chassis, so that save the man-hour of production and assembly and make things convenient for the user to fix or change hard disk.

The fixed mechanism of Winchester disk drive of the present utility model is characterized in, includes: a computer chassis base plate is provided with in the what computer chassis: a location-plate, join with described computer chassis base plate, and the top can fasten a side of a hard disk; And one fasten the unit, be oppositely arranged the opposite side of the described location-plate of what, in order to fasten another side of described hard disk, it has an a pair of holder and a fastening piece, wherein said fastening piece has a pair of jag and clip reed, described fixed seat side has a hole and a buckling groove, can snap in the hole of described holder by described jag, to be that the center is rotated its clip reed of an angle Hou and snapped in described buckling groove by described hole, so as to described hard disk being fixed by described location-plate and described fastening unit.

Therefore the fixed mechanism of Winchester disk drive of the present utility model can be when hard disk be resisted against location-plate, by the fastening of fastening piece and holder and with hard disk snapping what computer chassis base plate, so need not employ under the situation of any turnscrew, the user can be in free-hand mode hard disk in the fixing fast or dismounting computer chassis.

Adopt the fixed mechanism of hard disk of the present utility model can save the man-hour of assembling Fixed disk and make things convenient for user's dismounting.

Understand the purpose of this utility model, characteristics and advantage function thereof for clearer, preferred embodiment of the present utility model is elaborated below in conjunction with accompanying drawing.

Embodiment

As shown in Figures 1 and 2, the fixed mechanism of hard disk 40 of the present utility model is included in a location-plate 10 and fastening unit, wherein location-plate 10 and computer chassis base plate vertical connection is set on the computer chassis base plate in the computer chassis, one flanging 11 is arranged at the top, can fasten hard disk 40 sides; Described fastening unit has two major parts such as holder 20 and fastening piece 30, wherein fastening piece 30 has a pair of jag 31 and clip reed 32, its jag can be drawn in the hole 21 that snaps in holder 20, and with hole 21 is that the center is rotated an angle Hou and can be snapped in buckling groove 22 on the holder 20 with its clip reed 32 again, therefore this fixed mechanism can be when hard disk 40 be resisted against location-plate 10, by fastening piece 30 with the fastening of holder 20 with hard disk 40 snapping what computer chassis base plates.Therefore the utility model need not use under the situation of any turnscrew the hard disk 40 that mode fast assembling-disassembling that promptly can be free-hand is fixed.

For helping hard disk 40 can accurately locate when pushing location-plate 10 to, more satisfactory is on the screw hole position of what hard disk 40 sides corresponding teat 12 to be set relatively on the location-plate.Its effect is shown in Fig. 3 A to Fig. 3 D, and locate exactly to help hard disk 40 inside that can just insert the screw hole of hard disk 40 sides during the what assembling.

For further promoting fixing effect, fastening piece 30 still can be set up a rubber-like clamping part 34.Its effect can limit the activity of its vertical direction in order to the signature hard disk 40 of pulling shown in Fig. 3 D.

As shown in Figure 4, in order further to limit the activity space of hard disk 40 again in horizontal direction, but more satisfactory be to set up a pair of location division that overhangs 33 downwards on the aforesaid fastening piece 30 of what, so as to the activity at restriction hard disk 40 two ends.Enter easily for the jag 31 that makes fastening piece 30 in the hole 21 of holder 20, the described hole 21 other breach of can offering are inserted for the jag 31 of fastening piece 30.Inserting hole 21 Hous, shown in Fig. 3 C to Fig. 3 D, fastening piece 30 is a center rotation Hou with hole 21, and the clip reed 32 at fastening piece 30 two ends is snapped in the buckling groove 22 of holder 20, and fixing promptly announcement of hard disk 40 finished like this.

In order to guide hard disk 40 to rely on location-plate 10 smoothly and exactly to reduce the work that range estimation is aimed at, the utility model vertically is provided with a guide plate 23 again on chassis backplane, hard disk 40 can be moved along guide plate 23 and rely on location-plate 10, and this moment, teat 12 just inserted in the screw of corresponding hard disk 40 sides, so as to hard disk 40 1 sides being reached the fixing of left and right directions up and down.

Hou is with reference to figure 4.When being operated by what, an end of hard disk 40 must be plugged winding displacement, and therefore, the length of fastening piece 30 needs long than hard disk 40 captain's degree; In other words, more satisfactory is that an end of fastening piece 30 must reserve can be for the space of ccontaining thread plug and winding displacement.

The above only is full embodiment of the present utility model, is not to be used for limiting scope of the present utility model; The replacement of the variation of every all equivalences of being done according to the utility model spirit and equivalence is all the utility model patent protection scope and contains.
