Description
The invention relates to a kind of computer casing, particularly a kind ofly be provided with the computer casing that fixed cap can be convenient to the fixing expansion board.
Along with the continuous growth of computer function, computer inner more hardware of installing and software usually, expansion board is general modal expansion computer function device.With regard to existing general personal computer system, its system on the motherboard usually device various expansion boards with difference in functionality are arranged, comprise that roughly figure acceleration display card, video signal card, networking card and adlib etc. are used for promoting the computer system function.Correspondingly, the back plate of computer casing then is provided with several expansion draw-in grooves and is used to provide path and the fixing expansion board that expansion board externally connects.Correlation technique can be with reference to United States Patent (USP) the 4th, 744,006,4,979,075 and 5,121, No. 295 etc., these expansion boards be with screw locking near the back plate that expands draw-in groove one end, this kind obviously increases complexity and assembling man-hour of assembling process with the screw expansion board that locks one by one in the mode of back plate.Prior art also improves computer casing at this problem, but still remains to be improved part.
See also the computer casing 6 of No. the 88201721st, Taiwan patented claim shown in Figure 1, it comprises a back plate 62 and covers the fixed cap 64 on the plate 62 in the back, wherein back plate 62 is provided with the stator 622 that several expansion slots 620 are stamped to form by the back plate with the paths that expansion board 8 is provided externally connects and, this stator 622 is provided with several projections 624, and this expansion board 8 is provided with a kink 82 abutting on this stator 622, and this kink 82 is provided with a breach 84 and locatees this expansion board 8 with the projection 624 of accommodating on the stator 622.This fixed cap 64 is provided with several compressing tablets 642 and fixes this expansion board 8 with the corresponding kink 82 that pushes against at expansion board 8.This fixed cap 64 also is provided with a pair of through hole 644, is provided with a pair of threaded hole 626 at plate 62 after this relatively, thereby fixed cap 64 can be fixed on the plate 62 of back at the threaded hole 626 of back plate 62 by through hole 644 and the screw lock that pair of screws 66 is passed fixed cap 64.Though yet this 64 groups of fixed caps being consolidated at back plate 62 by the screw lock mode improved the shortcoming of prior art, but still have the factor of unfavorable raising packaging efficiency.Therefore, need a kind of installations simply, dismantle computer casing easily.
The object of the present invention is to provide a kind of have pivotable fixed cap so that loading and unloading expansion board computer casing.
Another object of the present invention is to provide a kind of have can conveniently fasten with the fastener that breaks away from fixed cap so that the computer casing of assembling.
By technique scheme, the present invention not only makes expansion board be convenient to loading and unloading, and a kind of fastener that can conveniently fasten and break away from fixed cap is provided.

Fig. 6 is fixedly expansion board but the fixing stereographic map of fixed cap of computer casing of the present invention.
Fig. 7 is the stereographic map of computer casing of the present invention.
Please consult Fig. 2 and Fig. 3 earlier, computer casing 1 of the present invention comprises back plate 2, is buckled in the fastener 3 of back plate 2 and is articulated in back plate 2 and can tighten the fixed cap 4 of fastener 3.The passage of several expansion slots 21 to accommodate expansion board 5 and to provide it externally to connect is provided this back plate 2.These expansion board 5 one ends are equiped with one and hide 51, and this covering 51 is provided with a kink 52, and are provided with a breach 54 on kink 52.Back plate 2 is being provided with a slotted hole 23 near these expansion slot 21 1 ends, and by a side of slotted hole 23 extend a stator 22 for hide 51 kink 52 against, and on the side of stator 22, be provided with the breach 54 of several projectioies 222 (consulting Fig. 5) to be housed in kink 52, locate this expansion board 5 by it.
Fixed cap 4 comprises the retaining sheet 42 that is located at two ends, be located at several shell fragments 44 of one side and be located at two depressions 46 of opposite side.This retaining sheet 42 is provided with a pivoted hole 422, and then plate 2 stators 22 are provided with protruding axle 224 to insert the pivoted hole 422 of fixed cap 4 at its both ends.
As Fig. 4 and shown in Figure 5, the clasp of fastener 3 passes wide 242 of back plate 2 through holes 24, and then the hook sheet 26 of plate 2 passes wide 344 of fastener 3 accepting holes 34.Simultaneously, cramp 292 deductions of back plate 2 are at fastener 3, and the projection 36 of fastener 3 is housed in the fixed orifice 27 of back plate 2, and the prominent point 38 (consulting Fig. 2) of fastener 3 is embedded in a shrinkage pool 28 of back plate 2, and the pulling part 32 of fastener 3 is housed in the top of rectangular opening 25.The protruding axle 224 of back plate 2 stators 22 is housed in the pivoted hole 422 of fixed cap 4 retaining sheets 42, thereby fixed cap 4 is articulated on the stator 22 of back plate 2.
As Figure 6 and Figure 7, rotational fixation lid 4 clasps 30 to fastener 3 pass depression 46 and are fastened on the plate 2 of back, and at this moment, shell fragment 44 deductions of fixed cap 4 fix expansion board 5 on the kink 52 of covering 51.Then, by pulling the mobile fastener 3 of pulling part 32 downward (as shown by arrow A), be housed in and only block fixed orifice 27 until the projection 36 of fastener 3, and the prominent point 38 of fastener 3 embeds next shrinkage pool 28 of back plates 2 at back plate 2.At this moment, the clasp 30 of fastener 3 is housed in narrow 244 of back plate 2 through holes 24, and then the hook sheet 26 of plate 2 is housed in narrow 342 of fastener 3 accepting holes 34 and detains and is against on the fastener 3.In this way, by fastener 3, fixed cap 4 firmly is combined on the plate 2 of back.
During dismounting, upwards (reverse with arrow A) pulls fastener 3 pulling parts 32 are housed in fixed cap 4 to the clasp 30 of fastener 3 depression 46, rotate this fixed cap 4 itself and fastener 3 broken away from, and the shell fragment 44 that goes to fixed cap 4 leaves and hide 51 kink 52, unload expansion board 5.So can be easily with expansion board 5 dismountings.
