Description

The shock attenuation device of computer housing

Technical field:

The utility model relates to the computer housing product technical field, is meant a kind of shock attenuation device of computer housing especially.

Background technology:

Along with the development of society, the raising of people's living standard, computer has progressed into common family.Present PC is broadly divided into from volume: desktop computer and notebook computer.Based on low price, be convenient to the consideration of factors such as product up-gradation, maintenance, maintenance, the computer type that desktop computer still is the individual at present, company used always.

Along with technical progress, computer hardware is also in develop rapidly.With the computer hard disc is example, and present computer hard disc memory space is bigger, and rotating speed is faster.This just requires it can be an environment operation stably.And present common desktop computer case can't reach this requirement.See Fig. 1,2, present computer housing comprises: casing 1, be installed in the left and

right side plate

11,12 of casing 1 both sides, casing 1 internal fixation have one be used to install hard disk support 3.These support 3 similar drawer structures, during installation, hard disk 14 is inserted by support 3 back end slots, the left and right sides of hard disk 14 offers positioning screw hole, hard disk 14 is fixed on the support 3 by screw 15 in support 3 left and right sides then, prevents that hard disk 14 from sliding in support 3.Adopt this mode to have following shortcoming:

1, trouble is installed, installs or during the dismounting hard disk, the

left side plate

11,12 of casing 1 all must be disassembled, just can unclamp then or trip bolt 15, at last hard disk 14 is taken off or fixing.

2, directly be fastened on the support 13 by screw owing to hard disk 14, hard disk 14 is without any buffering, and when type was subjected to impact, vibration, extraneous vibration was easy to hard disk is formed impact, causes hard disk impaired.Owing to adopt this mounting means, hard disk is when work simultaneously, and vibration, the noise that inner magnet produces when rotating is easy to be delivered to the outside by support 13, causes the cabinet noise excessive.

3, as shown in the figure, hard disk 14 by after insert forward in the support 13, the data line between mainboard and the hard disk 14, power lead directly are suspended at the space in the casing 1, so just cause in the casing 1 in a jumble, are not easy to maintenance computer, maintenance.

The utility model content:

Technical problem to be solved in the utility model is exactly in order to overcome the problem in the said goods, to propose a kind of shock attenuation device of computer housing, and it can effectively reduce the suffered impact of hard disk, and hard disk is formed protection.

Another technical matters to be solved in the utility model is exactly to overcome the problem that present hard disk is installed, dismounting is inconvenient, adopts this shock attenuation device to install, to dismantle hard disk easily.

For solving the problems of the technologies described above, the utility model has adopted following technical scheme: it comprises casing and is installed in the interior hard disk bracket of casing that hard disk is positioned at support, and hard disk is fixed by damping spring and support.

Described damping spring two ends form latch closure respectively, and two screws pass two latch closures and fix with hard disk and support respectively.

Offer scarce hole on the described support, damping spring is suspended at and lacks the place, hole site, promptly damping spring latch closure by screw retention at scarce bore edges, another latch closure by screw retention on the pilot hole on the hard disk.

Form a screens in the described casing, described support passes through the fastener inlay card of self in screens.

Described support rear and front end forms projection respectively, and support is overlapped on the screens dual-side by projection; Described fastener comprises: an elastic plate and be molded over stuck point on the elastic plate.

Be separated with a gap between being used to install between the side plate of computer main board and the support on the described casing.

After the utility model adopted technique scheme, at first, hard disk was fixed by damping spring and support, can play buffer action by damping spring, so that hard disk is protected; Simultaneously, hard disk is by behind the damping spring, and its operating room can be absorbed by damping spring because of inner magnetic disc rotates the vibration, the noise that cause, can reduce the noise of cabinet so greatly.Secondly the support that is used for fixing hard disk in the utility model adopts removably to be installed in the casing, and it adopts no screw fixation method, fixes in the inlay card mode, dismantles, installs all very convenient like this.

Embodiment:

See Fig. 3-6, the utility model comprises: casing 2, the support 3 that is used to install hard disk 4, damping spring 5 and screw 6.

Support 3 is a five metals framework, and hard disk 4 inserts in the support 3, is fixed on the support 3 by damping spring 5.

As shown in Figure 4,5 liang of ends of damping spring form the latch closure 51 that is parallel to each other respectively.During installation, two screws 6 are passed two latch closures 51 respectively, fixing with hard disk 4 and support 3 respectively again.Hard disk 4 just is suspended in the support 3 by damping spring 5 like this.Extraneous vibration, the formed momentum of impact can be dissolved the noise absorption that also hard disk 4 self can be sent because of vibrations simultaneously by damping spring 5.

Installation for the ease of damping spring 5, offer on the support 3 and lack hole 31, should lack hole 31 greater than damping spring 5, damping spring 5 just is suspended at and lacks 31 positions, hole, be that a latch closure 51 of damping spring 5 is fixed on by screw 6 and lacks 31 edges, hole, another latch closure 51 is fixed on the pilot hole 41 on the hard disk 4 by screw 6.

Mounting means between support 3 and the casing 2 is as follows: form a screens in the described casing 2, described support 3 passes through fastener 32 inlay cards of self in screens.Be specially: support 3 rear and front

ends form projection

33,34 respectively, and support 3 is overlapped on the screens dual-side by

projection

33,34; Described fastener 32 comprises: an elastic plate 321 and be molded over stuck point 322 on the elastic plate 321.During installation, support 3 is inserted in the screens, and make

projection

33,34 be overlapped on screens dual-side in the casing 2 respectively, the stuck point 322 on the fastener 32 just in time falls into the draw-in groove interior (scheming not shown) of screens side at this moment, forms inlay card and connects, and support 3 is fixing.If take off hard disk 4, push elastic plate 321 downwards, make stuck point 322 and draw-in groove break away from, then upwards firmly, support 3 is got final product by the screens extraction, very convenient.Whole dismounting process only needs to dismantle a side plate and gets final product, and need not dismounting near the side plate 21 of mainboard one side at all.

In addition, the utility model is in order to make the circuit in the casing 2 in order, is separated with a gap 20 between being used to install between the side plate 21 of computer main board and the support 3 on the described casing 2.The power lead of hard disk 4, data line can directly be connected with mainboard by the bottom near side plate 21 by this gap 20, and wire rod just can not be suspended in the casing 2 like this, make in the casing 2 neatlyer, be convenient to the user computer is keeped in repair, safeguards.

Certainly, the above only is example of the utility model, be not to limit the utility model practical range, all equivalences of doing according to the described structure of the utility model claim, feature and principle change or modify, and all should be included in the utility model claim.
