Description

Expansion card fixer

[technical field]

The utility model is about a kind of expansion card fixer, refers to a kind of without lock members such as screw and dismounting expansion card fixer fast and easily especially.

[background technology]

Active computer often need with the external unit swap data, it links to each other with external unit by the expansion board that is connected on the computer motherboard usually.This expansion board comprises that a plate body that links to each other with mainboard and has the stator of Peripheral Interface, this stator also comprises a folded angular surface, offer breach on the folded angular surface, often offer some expansion draw-in grooves behind the computer housing on the plate, these expansion draw-in groove one ends bend one folding piece and form a fluting outside casing, the breach of corresponding expansion board has some screws on this tabs.Pass in the fluting with the folded angular surface of expansion board stator plate behind this casing during installation, and with casing after the tabs of plate fit, the breach that afterwards screw is passed this folded angular surface locks together with the screw of corresponding tabs; When removing expansion board, must earlier screw be screwed out.Yet these fixed forms must be sealed with expansion board and casing by retaining elements such as screws, and dismounting or installation expansion board must be by related tools such as bottle openers, and process is comparatively loaded down with trivial details, unfavorable assembly and disassembly quickly and easily.

Disappearance at above-mentioned expansion board locking mode, the fixedly stationary installation of expansion board has appearred being specifically designed in industry, Taiwan is announced No. 472906 patent and has been disclosed a kind of in order to expansion board is fixed in the stationary installation of computer housing rear window, it comprises a deck body and is installed in the intrinsic at least one piece that presses of deck, wherein this presses piece and convexes with a pressure section, this deck body is provided with loading plate, this loading plate is provided with track, press piece and then offer guide groove to be contained in this loading plate slidably with respect to this track, press this contact level of deck that piece contacts with the deck body and offer first groove and second groove, press piece and then be provided with a card article at the wall that contacts with this this contact level of deck, with cooperating by card article and groove, make and press piece and be positioned on the appropriate location of loading plate, this press piece from the card article position also one be extended with an elasticity button, make card article can break away from the groove of this loading plate by pushing this elasticity button.This deck body periphery wall is provided with spiro-locking section, but the mat screw passes computer housing and spiro-locking section firmly is combined in the deck body on the computer housing, the loading plate of this deck body also is provided with some dowels, and the corresponding dowel in the location division of this casing rear window offers some pilot holes.During assembling, must be with the corresponding pilot hole that inserts casing of dowel, and deck body and casing are fixed by screw, when the locking expansion board, make to press piece and slide to this expansion board, compress the locking of finishing expansion board that cooperates of this expansion board and second groove by pressing piece card article and deck body to the pressure section that presses piece along the slideway of loading plate; During desire dismounting expansion board, push the button that presses piece earlier, its card article and second groove are separated, promote this then and press piece and discharge this expansion board.Yet, this stationary installation also must some screws and the dowel beginning can be fixed in casing, the dismounting complexity of stationary installation is loaded down with trivial details; And this presses, and relative motion is by the guide groove track structure between piece and the body, and the manufacturing accuracy of guide groove track is direct motion-affecting effect, thereby manufacturing accuracy is had relatively high expectations, and then increases manufacturing cost; Moreover the stationkeeping that presses piece is to reach by the card article groove structure, and whether also directly relevant with manufacturing accuracy the two engaging is firmly, and repeatedly uses the wearing and tearing of card article groove afterwards can influence the engaging effect of the two, and then influences fixing of expansion board.So this fixture structure complexity, it reaches the motion that presses between piece and the body by the guide groove track structure, reaches by the card article groove structure to press determining of piece position, reaches the locking of body and casing by some screws and dowel; Manufacturing accuracy is had relatively high expectations, and then promotes manufacturing cost.

[summary of the invention]

One of technical problem to be solved in the utility model is to provide a kind of simple in structure and expansion card fixer of assembly and disassembly expansion board quickly and easily, control and reduce the manufacturing cost of stationary installation when two of technical matters to be solved is to reach rapid and convenient dismounting expansion board.

The utility model solves the problems of the technologies described above by the following technical programs: the utility model expansion card fixer, be to be used for expansion board is fixed in the casing, it comprises one first fixed mount, one second fixed mount, a back plate and a side plate, this back plate is offered a breach from an edge, and this edge forms a pair of relative lappet in this breach certainly, offer a pivoting hole on these lappets respectively, this back plate is in abutting connection with this breach and be provided with some expansion draw-in grooves; These first fixed mount both ends are provided with a pivotal axis respectively, by these pivotal axis and cooperating of back plate pivoting hole this first fixed mount being fixed in the breach of this back plate rotationally; This second fixed mount is fixed in this first fixed mount, and this second fixed mount is provided with some abutting parts, and these abutting parts compress the end of expansion board and expansion board is fixed in the expansion draw-in groove; This side plate is this first fixed mount of butt and first fixed mount and second fixed mount are fixed in the back plate then.Wherein, this first fixed mount and this second fixed mount also can be integrally formed.

By above-mentioned embodiment, save the puzzlement of dismounting screw in the existing expansion board fixed solution, make assembling or dismounting expansion board become extremely convenient, and expansion card fixer of the present utility model do not have too high request to manufacturing accuracy, and then reduced manufacturing cost.
