Description

Computing machine peripheral element expansion card fixing device

[technical field]

The utility model relates to a kind of computing machine peripheral element expansion card fixing device, also is the pci card stationary installation, particularly a kind of fixing pci card stationary installation of screw that need not.

[background technology]

PCI (peripheral element extension interface) is as one of interface the most frequently used in the active computer technology, be applied to expanding the network and the multimedia performance of computing machine more, as sound card, network interface card, video frequency collection card and PCI video card etc., all pass through the PCI slot and be connected with the computing machine motherboard.

Because customer upgrade computer or otherwise needs, often need the loading and unloading pci card, in the prior art, adopt screw to fix to pci card more, at first pci card is inserted PCI slot corresponding on the computing machine motherboard, again pci card one side is fixed on the cabinet backboard with screw afterwards, so can the fixing PCI card.

Yet, adopt the fixing mode of screw when the loading and unloading pci card, there is complicated operation, time-consuming defective no matter still dismounting is installed, all need use specific purpose tool, and is as screwdriver etc., as if no specific purpose tool, at a loss what to do; In cargo handling process, also easily cause screw to be lost or fall into phenomenon in the cabinet, bring very big inconvenience to the user.

Therefore, be necessary to design a kind of need not in fact with the fixing pci card stationary installation of screw.

[summary of the invention]

The utility model provides a kind of easy to operate pci card stationary installation, to overcome in the conventional art pci card fixing operation complexity, time-consuming defective.

In order to achieve the above object, the utility model provides a kind of pci card stationary installation, comprise two identical bullet seats and a press strip, two bullet seats are individually fixed in the both sides of pci card fixed head on the cabinet inside backboard, press strip is positioned at PCI fixed head top, and this two bullets seat is hollow form, and this two bullets seat inside is respectively equipped with a connecting rod and an elastic body, this elastic body is positioned at bullet seat bottom, this connecting rod one end is connected with elastic body, and an other end of this connecting rod protrusion bullet seat inside is connected with an end of press strip, also promptly the connecting rod of two bullet seats is connected with the two ends of press strip respectively, also be provided with an elastic component in bullet seat inside on this connecting rod, this elastic component is closely against bullet seat madial wall owing to self elastic force; Be equipped with first hole clipping and second hole clipping on this two bullets seat sidewall, second hole clipping is positioned at directly over first hole clipping, and this two bullets seat outside is equipped with one with the first hole clipping correspondence position and ejects switch.

So push press strip during the fixing PCI card downwards, then connecting rod drives this elastic component and moves down, and pushes press strip to itself and PCI fixed head surface one side and joins, and this two elastic component is subjected to self elastic force and protrudes into and be stuck in two first hole clippings at this moment; Only need press the ejection switch on the two bullet seats during dismounting pci card, after being under pressure, elastic component is pressed in the bullet seat, this moment, elastic component was owing to be subjected to the elastic force of bullet seat bottom elastomeric, this two elastic component is upspring with connecting rod and press strip, and this elastic component so promptly reaches the purpose of conveniently assemble and disassemble pci card in the second hole clipping place protrudes into and be stuck in this second hole clipping.

Compared with prior art, the utility model utilizes two bullet seats to cooperate a press strip fixing PCI card, and all only with hand is gently one by get final product during pci card in installation and removal, and to load and unload the pci card process easy and convenient, time saving and energy saving thereby make.

For making the purpose of this utility model, structural attitude and function thereof there are further understanding, cooperate diagram to be described in detail as follows now:
