The fixing device of an extended card has no need of using screws, and has the advantage of simple and convenient installation and disassembly.

Description

Expansion card fixing device

[technical field]

The utility model relates to a kind of computer expansion card stationary installation, relates in particular to a kind of expansion card fixing device that does not have screw.

[background technology]

Usually be provided with a lot of expansion cards in the computer, as network interface card, sound card and video card etc. to realize different expanded functions.In the slot on the common base employing of such expansion card golden finger insertion computer main board, and the side of expansion card is provided with the I/O interface, and these interfaces pass the opening that is provided with on the computer chassis and are connected with external unit.The stator of a L type is set usually in the outside of these I/O interfaces, expansion card is fixed on the computer chassis by screw.

Owing to adopt screw to fix, when assembling, must adopt by complete machine the instrument of the turn of the screw, and cumbersome, and also built-up time is long, is unfavorable for saving manufacturing cost.And the client also must adopt the instrument of the turn of the screw in the time of needs dismounting computer, uses very inconvenience.

So the fixed form of necessary improvement computer expansion card, to overcome defective of the prior art.

[utility model content]

The purpose of this utility model is to provide a kind of simple and efficient computer expansion card stationary installation of assembling and dismantle.

For reaching above-mentioned purpose, the utility model adopts following technical scheme: a kind of expansion card fixing device, it comprises the lengthwise base portion that the stator of expansion card can be pressed against on the computer chassis, and is formed at and this stationary installation is fixed in fixed sturcture on the computer chassis on the base portion.

Compared with prior art, the utility model expansion card fixing device, it utilizes the lengthwise base portion that the stator of expansion card is pressed against on the computer chassis and fixes, and does not need to use screw, installs and dismantle easy.

[description of drawings]

Fig. 1 is the stereographic map of the utility model expansion card fixing device.

Fig. 2 is the stereographic map of another angle of expansion card fixing device shown in Figure 1.

Fig. 3 is that the utility model expansion card fixing device is installed on the synoptic diagram on the computer chassis.

[embodiment]

See also Figure 1 and Figure 2, the utility model expansion card fixing device 1, it comprises by sheet diapire 11 and the lengthwise grooved base portion 10 that surrounds with perpendicular madial wall 12 of diapire 11 and lateral wall 13.

Madial wall 12 includes the main part 121,131 identical with diapire 11 length with lateral wall 13, extends and the relative width stiff end 122,132 more smaller than main part 121,131 width that be bent to form with an end of the main part 121,131 of lateral wall 13 from madial wall 12.At the outwards outstanding respectively projection 123,133 of the outside surface of the stiff end 122,132 of madial wall 12 and lateral wall 13.

The other end at the main part 131 of lateral wall 13 extends to form extension 134 along main part 131 earlier, is bent to form bending part 135 from extension 134 inside sidewall 12 directions.

The other end relative with the stiff end 122,132 of aforementioned inside and outside sidewall 12,13 extends downwards and is bent to form buckling piece 111 on diapire 11.

Whenever keep at a certain distance away from the outside surface of madial wall 12 and to have extended to form number of plate-shaped cramp 124 downwards.

See also shown in Figure 3, when this expansion card fixing device 1 is installed on the computer chassis 2, the projection 123 of madial wall 12 stiff ends 122 is fixed in the circular hole 22 on the stator 21 of computer chassis 2, the projection 133 of the stiff end 132 of lateral wall 13 is fixed in the circular hole (not shown) on the computer chassis 2, and aforementioned two projections 123,133 are with expansion card fixing device 1 location.

Expansion card fixing device 1 can rotate to its diapire 11 around projection 123,133 and be posted by on the inwardly outstanding step 23 of computer chassis 2, the stator 3 of expansion card is pressed against between the outstanding step 23 of the diapire 11 of expansion card fixing device 1 and computer chassis 2 to be fixed.

The extension 134 of lateral wall 13 is snapped in the projection 24 times on the computer chassis 2.Buckling piece 111 on the diapire 11 is buckled on the side of outstanding step 23 of computer chassis 2 expansion card fixing device 1 is fixed on the computer chassis 2.The sheet cramp 124 that is positioned at madial wall 12 outsides this moment fastens expansion card stator 3 from side direction, guarantees that further expansion card stator 3 does not inwardly come off.

This expansion card fixing device does not need to use screw when mounted, and simple and fast is installed, and in the time of dismounting, the bending part that only need pull on the lateral wall is promptly detachable, handled easily.
