Description

Stationary installation

The utility model relates to a kind of stationary installation, especially a kind of interface card or circuit board is fixed on stationary installation on the appropriate location, computer chassis rear window location division.

In recent years, along with computer is changed in vogue with assembling DIY general mood at a low price, so assembled component is reduced, and make the user can simple and easy assembling apace or dismounting computer and inner member thereof become essential.

At present, device commonly used is seen Fig. 1, interface card 3 is fixed on the computer chassis rear window 2, wherein this interface card 3 is provided with a connecting piece 31 at the one end, the shape of connecting piece 31 1 end matching computer casing rear windows 2 is vertical bending and offers one can be corresponding to the hole clipping 32 of screw 23, when pushing against this connecting piece 31 on the appropriate location of computer chassis rear window 2 location divisions 23, the hole clipping 32 back screw locks that pass connecting piece 31 with a screw 5 in the screw 22 of computer chassis rear window 2, thereby reach fixing purpose.Because this assembling mode needs with screw 5 interface card 3 to be fixed on the computer chassis rear window 2, makes interface card install firmly inadequately, must utilize instrument (turnscrew) fixed screw 5 in addition, the inconvenience that causes the user to assemble, dismantle.

The purpose of this utility model provide a kind of need not screw when being fixed on circuit board or interface card on the computer chassis, can assemble fast and dismantle and can guarantee that overall package is firm, make the stationary installation of the stable signal transmission on the circuit board.

The utility model is achieved in that a kind of stationary installation, comprises a deck body and is installed in the intrinsic at least one piece that presses of deck; This deck body is fixedlyed connected with computer chassis rear window location division, and this presses piece and the deck body is slidingly connected, press piece when in the deck body, sliding onto the second place by primary importance and the connecting piece of external clamp fasten fixing.

The deck body is provided with loading plate, is provided with between the loading plate and can installs the accommodation space that presses piece, and loading plate is provided with track, presses piece and is provided with the guide groove that it is slided along track corresponding to the track place on the loading plate.

Press piece and convex with one when pressing the pressure section that can press against external clamp connecting piece surface when piece slides onto the second place at wall place near the computer chassis rear window.

The aforementioned primary importance and the second place are respectively and are located at first groove and second groove that presses this contact level of deck that piece contacts with the deck body; Press piece and be provided with a card article at the wall that contacts with this contact level of deck, card article and groove fit press piece and are positioned on the loading plate.

Press piece and be extended with an elasticity button in the position one that is provided with card article, push button, card article can break away from the groove of deck body wall, removes to press the positioning states of piece on loading plate.

This deck body is provided with loading plate, and a side of the nearly computer chassis rear window of loading plate is provided with and the corresponding register pin of computer chassis pilot hole.

Deck body periphery wall is provided with available screw and is fixed in spiro-locking section on the computer chassis.

This external clamp is interface card or circuit board.

Stationary installation provided by the utility model, because pressing piece can slippage in the deck body, when circuit board is positioned on the computer chassis by the deck body, push the elasticity button that presses piece, to press piece primary importance in the deck body slides to the second place and fastens circuit board, then need not use other instruments can be assembled in circuit board on the appropriate location of computer chassis rear window fast, push the elasticity button that presses piece, to press piece second place in the deck body and slide to primary importance, promptly unclamp the circuit board that fastens, also can apace it be disassembled; Again because the loading plate of deck body is provided with first groove and second groove, the card article that presses on the piece cooperates with draw-in groove, make and press piece when slippage is located, the energy strong fix is on the appropriate location of loading plate, when the card article that presses piece fastens in second draw-in groove, the connecting piece that fastens circuit board one end can be stablized in the pressure section that presses on the piece, guarantees the beneficial effect that overall package is firm.

See also Fig. 2, shown in Figure 3, the interface card 3 that stationary installation 1 can be provided with an end connecting piece 31 is fixed on the location division 23 of computer chassis rear window 2, this stationary installation 1 includes a deck body 11 and is installed in and presses piece 12 in the deck body 11, wherein 23 places, location division corresponding to computer chassis rear window 2 are provided with loading plate 111 in this deck body 11, and formation accommodation space 110 presses piece 12 to install this.And on adjacent two loading plates, 111 opposite faces, be provided with track 112, press piece 12 and then offer guide groove 121 with respect to this track 112, make press piece 12 can slippage in its deck body 11.On deck body 11 surface of contact 117 of 111 of two adjacent loading plates, then offer first groove 115 and second groove 116 respectively away from the appropriate position that reaches near computer chassis rear window 2.

Convex with a pressure section 123 at the aforementioned piece 12 that presses in a side of nearly computer chassis rear window 2, the surface of surface of contact 117 convexes with a card article 124 in corresponding to deck body 11, by means of cooperating of card article 124 and groove 115,116, make to press piece card 12 and can be positioned on the appropriate location of loading plate 111.In addition, press piece 12 and be extended with an elasticity button 122,, make card article 124 can break away from the groove 115,116 of loading plate 111 by to the pushing of button 122 in the position one that is provided with card article 124, releasing presses the positioning states of piece 12 on deck body 11, makes it can continue slippage.

Side at the loading plate 111 nearly computer chassis rear windows 2 of deck body 11 is provided with register pin 114, and the location division 23 of computer chassis rear window 2 offers pilot hole 21 corresponding to register pin 114 places, 11 groups of deck bodies can be located on the appropriate location of computer chassis rear window 2 one sides.Be provided with a plurality of spiro-locking sections 113 at deck body 11 periphery walls, available screw 13 passes computer chassis 4 and spiro-locking section 113 (seeing also Fig. 4, shown in Figure 5), and deck body 11 firmly is combined on the computer chassis 4.

See also Fig. 5, Fig. 6, when stationary installation 1 is assembled in interface card 3 on the location division of computer chassis rear window 2, the end that the connecting piece 31 of interface card 3 is vertical bending fastens in the accommodation space 110 that two adjacent in deck body 11 loading plates 111 ask, make it Primary Location, push the former elasticity button 122 that presses piece 12 this moment primary importance (card article 124 that press piece 12 this moment fastens in first groove 115), can make card article spare 124 break away from first groove 115, direction slippage to computer chassis rear window 2 location divisions 23, when sliding onto the second place (card article 124 that press piece 12 this moment fastens in second groove 116), pressing the wall 120 of piece 12 nearly location divisions 23 and pressure section 123 can be on laterally and vertical urgent connecting piece 31 bending sides and the surface that compresses interface card 3, thereby reaches firm assembling and do not understand the outer effect that falls.

Otherwise, when interface card 1 is removed on the location division 23 of computer chassis rear window 2 (figure do not show),, make card article 124 break away from second groove 116 as long as push the elasticity button 122 that presses piece 12, will press piece 12 again and slide onto primary importance and get final product.
