Description
Technical field
The present invention relates to a kind of stationary installation that need not use screw, particularly relate to a kind of stationary installation that is used for fixing personal computer add-on card.
Background technology
As if personal computer is more and more universal at present, has become a kind of daily necessities, no longer is to have only the technical skill personnel just to understand the high-tech product of use, the user is familiar more to computing machine, and is also just deep more to the understanding of computer hardware.Therefore, have now and only buy the suit computing machine and use its way can not describe user's behavior pattern, the computing machine that meets own demand most of can trying to build of user now, therefore own purchase hardware is assembled computing machine has become a kind of very general and economic way.Moreover, computing machine science and technology is advanced by leaps and bounds, and the speed that the more outstanding hardware of function is released makes people's dim eyesight formal confused; personal computer regular meeting faces the situation that is out of step with the times soon; at this time, suitably " upgrading " computing machine can be gone many than buying computing machine reality and economy again.
By above explanation as can be known, personal computer must possess hardware and install to be easy to characteristic now, needs that can the person of being used.In various hardware devices, additional card miscellaneous can be said so, and the most common also common people were familiar with the most, for example display card, sound card and network card etc., the user install and the chance of eliminating these additional card of making pottery also maximum, below the way that is configured in the personal computer at present additional card give and simple declaration.
Please refer to Fig. 1, it is configured in traditional method synoptic diagram in the personal computer for additional card.With present way, the inboard of personal computer backboard can dispose pickup groove module 101, and pickup groove module 101 is provided with several (for example being seven) additional card pickup grooves 102, is used for fixing additional card 110.The side that it should be noted that additional card 110 disposes cutting 111, and utilizes the crooked laterally end of cutting 111 as stator 112, is used for following fixed pan 104 applyings of pickup groove module 101.When being installed in additional card 110 in the personal computer, the additional card slot (not being illustrated among the figure) that can earlier additional card 110 be inserted on the motherboard, and allow cutting 111 be covered in additional card pickup groove 102 places, the joint (not illustrating) of additional card 110 can be come out by additional card pickup groove 102, peg graft with external device (for example display or loudspeaker etc.) with convenient.Certainly, for stator 112 and fixed pan 104 are fitted tightly, can form on the stator 112 as graphic as rectangular indentation, and also be provided with several screw holes 103 on the fixed pan 104, after stator 112 and fixed pan 104 were fitted, rectangular indentation just can be aimed at screw hole 103, thus, only need screw is locked in the screw hole 103, additional card 110 lockings can be finished the action of installation.
By above explanation as can be known, with present way, though can reach the purpose that additional card is installed, but owing to must use screw, turnscrew has become indispensable instrument, has lost maneuverability and the convenience installed, and has been easy to when mounted tiny screw is dropped so that lose, even the user brings very big puzzlement when mounted probably because setting angle is cunning or technology is unskillful and cause hand to be bled by incised wound to the user.
Summary of the invention
The object of the present invention is to provide a kind of screw-free fixing device, be used for fixing the additional card in the personal computer, installing or making pottery when eliminating additional card, more more convenient and rapid than traditional way.
The object of the present invention is achieved like this, a kind of screw-free fixing device promptly is provided, additional card in order to fixed personal computers, this personal computer comprises a backboard and a pickup groove module, this pickup groove block configuration is in the inboard of this backboard and comprise a plurality of additional card pickup grooves, in order to dispose at least one additional card, this pickup groove module has a fixed pan, this additional card comprises that a distolateral bending of a cutting and this cutting is to form a stator, wherein when this additional card of configuration, this stator and this fixed pan are fitted and this cutting is covered on this additional card pickup groove, this is exempted from the helical stationary installation and comprises: a supporting seat, in order to affixed with the backboard of this personal computer, and the side on this supporting seat surface also disposes a support rotary seat; One rotation compressing tablet, the side of this rotation compressing tablet disposes a compressing tablet rotating shaft,, this compressing tablet rotating shaft and this support rotary seat adopt rotatable mode to couple, the surface of this rotation compressing tablet also disposes a sleeve joint device, and this sleeve joint device comprises one first socket end and one second socket end;
Positioning piece is disposed at the inboard of this backboard; An and elastic wire, its two ends are bending in the same way, the end that this elastic wire bent forms the other end that one first sleeve and this elastic wire bent and forms one second sleeve, wherein, the second socket end socket of first socket end socket of first sleeve of this elastic wire and this rotation compressing tablet and second sleeve of this elastic wire and this rotation compressing tablet is so that this elastic wire rotatably couples with this rotation compressing tablet; Can make this rotation compressing tablet be stable in this fixed pan when wherein, this elastic wire rotates to this keeper snapping sentences and presses solidly this additional card.
When additional card is installed, as long as elastic wire is mentioned, unclamp buckle state, make the rotation compressing tablet can rotate to opening, just can pull down the additional card that will make pottery and eliminate.After installing new additional card, will rotate compressing tablet again and rotate to the state of pressing solidly, and depress elastic wire and make it to get final product with the keeper snapping is fixing.Because process does not need to use screw fully,, not only save time but also convenient, safety so also do not need extra instrument.
The advantage of apparatus of the present invention is that it need not use any instrument, and the dismounting of additional card can be carried out in any situation; Do not use the screw of tiny easy loss during the dismounting additional card, the puzzlement that can avoid losing screw; It is simple in structure easy to use, and the user can buy back voluntarily and to install, and equips so can orientate apolegamy as, makes things convenient for marketing promotion.
