Abstract
The utility model discloses a PCI card fixing mechanism which comprises an external shell and a locking member. The external shell is provided with a frame which is form with a plurality of narrow windows to expose the PCI card and a support board extending upwards from the frame. The support board includes a pair of guiding slots paralleled the windows and a pair of assembling notches on the top edge of the support board. The locking member has a pair of mainbodys connected to the bridge in the guiding slots in a sliding way, a pair of pulling parts disposed in the assembling notches and extended outwards from the top edge of the mainbody, and a crimping board formed by bending bottom flange of the mainbody which pressed the edge of the frame to fix the PCI card. The utility fixes the PCI card by pressing blocking sheet on the top of the locking member, without disassembling the device and bolts. When unlocking the PCI card, the blocking sheet on the top is pressed and the blocking part is pulled upwards to make the crimping board separate from the the PCI card, therefor simplifying thelocking and unlocking operations.
Description
Technical field
The utility model relates to the local bus-bar of a kind of outer pass component interconnect, and (this mechanism is in order to be fixed in pci card on the main case of computer for Peripheral ComponentInterconnect, PCI) card fixing mechanism.The utility model relates in particular to a kind of pci card fixed mechanism that does not need instrument and screw.
Background technology
Pci card (Peripheral Component Interconnect closes the local bus-bar card of component interconnect outward) is widely used in the computer at present.PCI is a kind of bus-bar (Bus) framework, is used for connecting data card, display card, adlib or other ancillary equipment.
The mode of at present common fixing PCI card nearly all is to use screw to fix, this fixed form not only needs to increase the step of locking screw in operation, and need tighten the bar awl of (or unscrewing) screw, therefore, not only time-consuming but also make us feeling trouble in operation, and screw is lost easily.What is more, undiscovered if screw drops on motherboard, will cause the motherboard short circuit when booting computer, and then cause heavy losses.
From the above, existing P CI card fixing mechanism is very inconvenient and lose easily on reality is used, so the utmost point is waited to improve.
So the inventor has carried out this concentrating on studies and to use the principle of learning to propose finally a kind of reasonable in design and overcome the technical scheme of above-mentioned defective effectively.
The utility model content
The technical problems to be solved in the utility model is, a kind of pci card fixed mechanism is provided, and the operator does not need other instruments and object can fix and unload pci card, thereby can avoid screw to drop and the motherboard short circuit that causes.In addition, can remove convenient and apace and fix, to save the time of knockout screw.
The technical scheme that solves described problem is that the pci card fixed mechanism that is used for fixing pci card of the present utility model comprises extension case and locking part.This extension case has: be formed with a plurality of thin-and-long windows so that the window-frame that pci card exposes; With by the upwardly extending bearing plate of window-frame.Bearing plate has: pair of parallel is in the guide groove and a pair of assembling notch that is formed at the apical margin of bearing plate of window.Locking part has: body, this body have a pair of bridge formation that is slidably connected in the described a pair of guide groove; The outward extending pulling part of a pair of apical margin by body, they lay respectively in the described a pair of assembling notch; Root edge by body bends the crimping plate that forms, and this crimping plate is pushed down the edge of window-frame with the fixing PCI card.
Compared with prior art, the utility model does not need extracting tool and screw, only need up spur the stationary state that locking part can be removed pci card fast.

Please consult Fig. 1 again, slide on bearing plate 14 more swimmingly for making locking part 20, in the utility model, the body 21 of locking part 20 also is formed with a pair of Location resilient piece 25a and 25b, flexibly to be connected to bearing plate 14.Wherein, the free end at Location resilient piece 25a and 25b is formed with positioning convex point 252 respectively, and bearing plate 14 is formed with a plurality of and Location resilient piece 25a and 25b corresponding positioning hole 141,142.Can reduce the frictional force between locking part 20 and the bearing plate 14 whereby, but and auxiliary lock firmware 20 in special location positioning on bearing plate 14.For example, if pull-up locking part 20, can be located in unlocked position (position of location hole 141) and be unlikely to glide.(as shown in Figures 3 and 4.)
In addition, in the present embodiment, bearing plate 14 also is formed with Location resilient piece 17, and the free end of this Location resilient piece 17 is formed with positioning convex point 172, and the body 21 of locking part 20 is formed with and Location resilient piece 17 corresponding guiding chases 212.
For fixing PCI card 30, in the utility model, make the crimping plate 24 downward punching presses of locking part 20 form a plurality of retention tab 242, in order to the slotted vane 32 of fixing PCI card 30.In addition, respectively the edge of the crimping plate 24 of locking part 20 is bent to form retaining edge 244,246 downwards.
Mode of operation
See also Fig. 5 and Fig. 6, they are respectively the front view and the rearview of pci card fixed mechanism of the present utility model (behind the locking pci card).Now mode of operation of the present utility model is described below: when needing locking pci card 30, depress the catch 222 on locking part 20 tops and can fix. Bridge formation 23a and 23b along guide groove to 15a and 15b to lower slider, and crimping plate 24 fixing PCI card 30 downwards thereupon.
See also Fig. 7 and Fig. 8, they are the three-dimensional combination figure of the utility model pci card fixed mechanism (behind the locking pci card).In the time of need unloading pci card, upwards pull stop section 26, can make crimping plate 24 leave pci card 30.In sum, the utility model is very easy in the operation of locking and releasing stationary state.
Feature of the present utility model and advantage
One, pci card fixed mechanism of the present utility model does not need extracting tool and screw, only need up spur the stationary state that locking part can be removed pci card fast; Can the fixing PCI card if down promote locking part.
Two, pci card fixed mechanism of the present utility model utilizes ironware design flexibility slide rail, and utilizes the retaining edge 244,246 of crimping plate 24 or the function that retention tab 242 realizes the fixing PCI card.
The above only is a preferred implementation of the present utility model; and be not to be to restriction of the present utility model; therefore, any equivalents of making in the protection range that the utility model claim is limited or modification all will be covered by in the scope of the present utility model.
