Description

The motherboard fixed mechanism

Technical field

The utility model relates to a kind of fixed mechanism, particularly a kind of fixed mechanism that is used for fixing motherboard.

Background technology

Along with the development of Information technology, computing machine has become people and has worked and go up and even in lifely can not obtain scarce instrument.Popularizing of computing machine has been inevitable trend, and along with the increase day by day of demand, the function of computing machine also from strength to strength, the thing that can help people also is more and more.In order to allow computing machine carry out the thing of various people's demands, the upgrading of hardware aspect is can hardly be avoided, and also is the comparatively economic practice.

Wherein the motherboard of computing machine has accounted for sizable part, motherboard fixed form in the past all is to utilize to be fixed with a plurality of pillars with thread on the main frame, utilizing screw motherboard to be fixed on these pillars, it is fixing on the one hand, is on the other hand motherboard and casing are separated in order to avoid damage.Sometimes, to be on the safe side and the possibility of avoiding producing short circuit, can increase insulating trip between screw and the motherboard and between motherboard and the pillar.

Though this fixed form can be fixed motherboard firmly, but but quite expend the time of assembling, and because on the motherboard many pins and electronic package are arranged, it is quite very difficult installing on the narrow and small computer housing in space, and accidentally be easy to will be by itself or casing scratch, if install insulating trip again additional, be difficult to especially its man-hour estimate.

What the assembling person on the production line expended maximum times at the end of the day nearly all is on the assembling motherboard, the installation that general individual uses even say so, though only be the assembling oneself one, also tend to install to a face streaming with sweat, or even install to hand scarred adorn bad.And now computer hardware to eliminate the rate of changing quite high, assembling for convenience or change, its fixed sturcture truly have its improved necessity.

The utility model content

The utility model aims to provide a kind of fixed mechanism of motherboard for addressing the above problem, and it need not use the screw can the fixed host computer plate, and assembling and change all quite convenient.

According to the fixed mechanism of the motherboard that the utility model disclosed, it comprises: a cramp, a slide plate and an elastic parts, and cramp one end is articulated on the computer housing, and the other end forms a square groove, and the middle part has a grab; Slide plate has a draw-in groove, and is limited on the computer housing, only can make folk prescription and slide forwards, backwards; Elastic parts one end is fixed in computer housing, and the other end is fixed in slide plate one end; When the fixed host computer plate, rotate cramp, make its square groove prop up the edge of motherboard, it is fixed towards a side, at this moment, grab can fasten with this draw-in groove, and by elastic parts, cramp and slide plate are maintained the state of fastening, and so, need not screw can fix motherboard.

For further specifying above-mentioned purpose of the present utility model, design feature and effect, the utility model is described in detail below with reference to accompanying drawing.

Fig. 1 is a synoptic diagram of the present utility model;

Fig. 2 A, Fig. 2 B are action synoptic diagram of the present utility model; And

Fig. 3 A, Fig. 3 B are the bonding state figure of the utility model pillar.

Embodiment

According to the fixed mechanism of the motherboard that the utility model disclosed, as shown in Figure 1, it comprises: a cramp 10, a slide plate 20 and an elastic parts (be a spring 30 shown in the figure, below be that example is done explanation with spring 30 only).One end of cramp 10 has a pivoted pole 103, can pack into by in the two upright pivoted holes 402 on the computer housing 40, and make cramp 10 to rotate with respect to computer housing 40 for axle by pivoted pole 103.The other end of cramp 10 has a square groove 101, and square groove 101 can be formed by cramp 10 front end bendings, and can prop up the edge of motherboard, and the middle part has a grab 102, and both sides are extended circular arc spare 104 downwards.

Slide plate 20 is installed in cramp 10 belows, and is limited by the chute on the computer housing 40 401, and only can slide before and after the long axis direction of chute 401 is done.Chute 401 can be by directly being stamped to form on the computer housing 40, and the middle part has a draw-in groove 201, can be for the usefulness of grab 102 engagings of cramp 10, and an end extends upward a plectrum 202, promotes slide plate 20 to make things convenient for the user.Spring 30 two ends respectively have a fixed hook 301, one ends to be fixed on the computer housing 40, and the other end is fixed in slide plate 20.

During assembling, see also Fig. 2 A, motherboard 50 is placed on the pillar 403 of computer housing 40, certainly, one side must snap on the computer housing 40, make each connectivity port (for example being PS2 or printer connectivity port etc.) on the motherboard 50, can expose outside the computer housing 40, use for the user.Rotate cramp 10, make its square groove 101 prop up the edge of motherboard 50, and motherboard 50 is blocked to a side, at this moment, grab 102 on the cramp 10 can engage with draw-in groove 201, and cramp 10 is fixed on this position (seeing 2B figure), and is maintained by spring 30, cramp 10.Because a side of motherboard 50 is blocked (just a side of connectivity port, the left side among the figure) for computer housing 50, the square groove 101 of adding cramp 10 at this moment props up its edge, so motherboard 50 can be fixed.And the circular arc spare 104 of cramp 10 provides an elastic force that makes progress, to guarantee the tight buckling state of grab 102 and draw-in groove 201.

And in the time will changing or take off motherboard 50, only need utilize plectrum 202, slide plate 20 is pushed away forward, just the direction to motherboard 50 pushes away (left side shown in the figure), make the grab 102 of cramp 10 break away from the draw-in groove 201 on the slide plates 20, by the elastic force of circular arc spare 104, cramp 10 is upspring, and can take off motherboard 50 (just being returned to state) then as Fig. 2 A.

And in order to guarantee the stationary state of motherboard 50 more, can utilize the pillar 403 on the computer housing 40, has a head 4031 less than fixed orifice 501 apertures of motherboard 50, and a neck 4032 (see Fig. 3 A) adjacent with head 4031, and the length of neck 4032 is greater than the thickness of motherboard 50.During assembling, fixed orifice on the motherboard 50 501 is inserted in neck 4032 by head 4031, after rotation cramp 10 is fixed, can force motherboard 50 to be moved to the left and be stuck in neck 4,032 one sides (seeing Fig. 3 B), just motherboard 50 is stuck under the head 4031, so, motherboard 50 is more firmly fixed.

But the utility model need not just fixed host computer plate of screw, and it is auxiliary to change the motherboard tool free, can save assembling man-hour, and the replacing when making things convenient for upgrading computer.

Certainly, those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the utility model, and be not to be used as qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in the scope of the utility model claims variation, the modification of the above embodiment.
