New description: [New technical field] 礴 This creation involves an expansion card blank fixing device, especially an expansion card blank fixing device with simple structure and convenient assembly. [Prior Art] In order to improve the computer function, it is generally achieved by adding an expansion card. As far as PCs are concerned, they are usually equipped with expansion cards for various functions, such as graphics acceleration display cards, video cards, network cards and sound effects cards. In order to stably fix the expansion cards inside the computer for good signal and electrical connection, a plurality of expansion cards are usually provided on the rear window of the rear panel of the computer casing to mount the expansion cards. In the prior art, such as an expansion card fixing device, one side of the expansion card is first fixed to a metal blocking piece, and then the metal blocking piece is locked by screws to the expansion card slot of the rear window of the computer to be fixed. Expansion card. This type of expansion • Card fixing method requires a screwdriver to lock the screw to the Φ metal blank and the rear plate of the expansion card. The assembly process is cumbersome and time-consuming, which affects the product's production efficiency. Another type of expansion card fixing device uses a bead to fix a plurality of sheets of the expansion card to the window frame of the computer base, and then flips the other end of the bead downward, when the bead abuts the flaps. The other end of the bead is fixed to the window frame by a screw to fix the expansion card cover to the computer base. Although the fixing method facilitates the disassembly and assembly of the expansion card, it is still cumbersome to realize the final fixing of the expansion card blank through the screw. 6 M318303 [New Content] In view of the above, it is necessary to provide an expansion card support device that is simple in structure and convenient to assemble and disassemble. An expansion card blank fixing device for fixing at least one expansion card blank, comprising: a base and a fastening component for fixing the expansion card blank to the base, the base being provided with at least one pivot a latching member, wherein the latching member is provided with at least one flap correspondingly pivoted in the pivoting slot and a hook hooking the outside of the base when the latching member is rotated into position, the flap of the latching member A hook portion extending from the pivoting groove of the base and engaging the inside of the base is included. Compared with the prior art, the expansion card blank fixing device fixes the expansion card blank to the base through a fastening component mounted on the base, and only needs to rotate the fastening component during installation. It can be fixed in place; when disassembling, simply remove the fastener to remove the expansion card blank. The expansion card retaining device has a simple structure and is convenient for disassembly and operation. [Embodiment] Referring to FIG. 1 , a preferred embodiment of the present expansion card blank fixing device includes a base 10 and a fastening component 20 for fixing a plurality of expansion card blanks 30 to the base 10 .

The pivoting groove 141 includes a pair of pivoting grooves 141 . A long slot portion 141a and a short slot portion 141b that penetrates the slot portion 141a. The flange 14 is provided with a horizontal elastic piece 143 and a slot 145 disposed under the elastic piece 143. The rear plate 12 is provided with a recess 147 below the elastic piece 143. Referring to FIG. 1 and FIG. 3 , the latching member 20 includes a latching surface 22 and a side panel 24 perpendicularly connected to the latching surface 22 , the latching surface 22 corresponding to the notch 32 of the expansion latching tab 30 and the The convex portion 1231 of the base 10 defines a plurality of fixing holes 221, and one side of each fixing hole 221 is provided with an elastic pressing piece 223. The upper edge of the side plate 24 is provided with a pair of folding points corresponding to the pivoting groove 141 of the base 10. Each of the flaps 241 includes a shorter neck portion 241a extending from the upper edge of the side panel 24 and a longer hook portion 241b extending horizontally from the neck portion 241a. The hook portion 241b is located The plane is perpendicular to the side panel 24 of the snap member 20 and is directed opposite the orientation of the slot portion 141a of the pivot slot 141. The latching member 20 is provided with a recessed portion 245 corresponding to the recess 147 of the rear plate 12 of the base 10 between the two flaps 241. The recessed portion 245 extends upward to form a hook portion 241b perpendicular to the flap 241. Tongue 243. The latching member 20 further includes a resilient handle 26 extending downwardly from the latching surface 22, and a hook 261 is disposed on the inner side of the latching member 26. Continuing to refer to FIG. 4 , the expansion card blank 30 is correspondingly disposed in the expansion card slot 121 of the base 10 , and the notch 32 of the expansion card blank 30 is correspondingly sleeved on the base 10 . Then, the side plate 24 of the latching member 20 is inserted into the pivoting groove 141 correspondingly to the flap 241 of the latching member 20 of the latching member 20; The tab 243 is horizontally inserted into the base 10 from the slot 145 of the base 10, and then the latch member 20 is translated to the left so that the neck portion 241a of the flap 241 correspondingly falls into the pivot of the base 10. The hook portion 241b of the flap 241 protrudes from the pivot groove 141 into the base 10 and hooks the inner side surface of the base 10; finally, the latch member 20 is finally disposed. The lower side edge of the locking groove 141 of the pivoting groove 141 is rotated 90 degrees downward in the rotation direction, so that the fixing hole 221 of the locking member 20 is sleeved on the convex portion 1231 of the base 10, the fastening component The latching surface 22 of the latching member 22 presses the latching tab 30 of the latching member 20, and the latching hook 261 of the latching member 26 hooks the lower side edge of the supporting frame 123 of the base 10 to prevent the latching member 20 from being reversed upward. , the fastener 20 The recessed portion 245 is located in the recess 147 of the base 10. The elastic piece 143 of the base 10 vertically presses the tab 243 of the latching member 20, and the elastic pressing piece 223 of the latching member 20 also presses the latching portion 223. The expansion card blank 30, at this point, the snap member 20 is rotated into position to secure the expansion card blank 30 to the rear panel 12 of the base 10.
