Description of the Invention: [Technical Field] The present invention relates to an expansion card baffle fixing device and a computer case having the expansion card baffle fixing device. [Previous Technique #f] [0002] Conventional computers often need to exchange data with external devices, which are usually connected to external devices through expansion cards connected to the computer motherboard. The expansion card is installed in the slot of the computer motherboard. During the process of moving the computer or when the computer is accidentally impacted, the expansion card will loosely shake or even fall off, which may cause damage to the expansion card and the motherboard slot. Occurs, the expansion card needs to be firmly fixed to the computer case. [0003] In the prior art, the expansion card includes a board body connected to the motherboard and a baffle having an interface of the external device. The baffle is generally in an "L" shape. When the expansion card is inserted into the slot of the motherboard, the expansion card is used. The plurality of screws lock the bezel to the rear panel of the computer case, thereby achieving the purpose of firmly fixing the expansion card. However, such an expansion card baffle must be fixed by using a locking component such as a screw, which is cumbersome to install and disassemble, and is time consuming and labor intensive. SUMMARY OF THE INVENTION [0004] In view of the above, it is necessary to provide an expansion card baffle fixing device which is simple in structure, convenient in operation, and a computer case having the same.

[0013] Referring to FIG. 3 and FIG. 5 together, the latching member 50 includes two spaced opposite pivoting portions 51 and an opposite one connected to the same end of the two pivoting portions 51. a connecting portion 53 of the first side surface 531 and a second side surface 533, and two protruding portions 513 protruding from the two pivoting portions 51 and protruding from the first side surface 531 of the connecting portion 53 and the connecting portion 53 An "L" shaped buckle 55 projecting from one end of the pivoting portion 51 and projecting from the second side 533 of the connecting portion 53. A second pivot shaft 512 is outwardly protruded from a side of each of the pivoting portions 51 facing away from the pivot portion 51 opposite thereto. Each of the protrusions 513 is provided with a slope 511 inclined to the first side surface 531 of the connecting portion 53. The slope 511 is provided with a recess 514. A sidewall of the recess 514 adjacent to the buckle 55 is in the recess. The opening of the 514 forms an arcuate corner 515 with the bevel 511. A side wall of the recess 514 away from the buckle 55 forms an abutting wall 516. The buckle 55 includes a pressing portion 551 extending perpendicularly from the second side surface 533 of the connecting portion 53 and a locking portion 5 5 extending perpendicularly to the pressing portion 551 away from the connecting portion 53. . Referring to FIG. 1 to FIG. 3, the fixing plate 31 of the fixing base 30 is mounted on the mounting area 23 of the rear plate 20 of the computer case through a common fixing manner such as a sticking or locking screw, so that the fixing seat 30 is located. Just above the slot. The two fixing arms 33 of the fixing member 30 are slid outwardly, and the two first pivoting shafts 47 of the operating member 40 are respectively slid along the two guiding grooves 336 of the first pivoting holes 331 of the two fixed arms 33. The two first frame turning holes 3 31 are inserted later. The two pivoting portions 51 and the protruding portions 513 of the latching member 50 are rotatably inserted into the two apex blocks 45 of the workpiece 098113260, Form No. A0101, Page 7 of 18, 0982022141-0, 201039098 a gap 46 between the triggering portions 41, the two fixed arms 33' of the fixing base 30 are externally plated, so that the two second pivoting corrections 12 of the locking member 5 are respectively along the two fixed arms 33 The two guiding grooves 336 corresponding to the two pivot holes are inserted into the two second rotating holes, and the two abutting blocks 45# of the operating member 40 are respectively received in the concave portions of the two-pole rotating portion 51 of the locking member 5Q. Slot 514. Thus, the operating member 4 is engaged with the latching member 5. Rotatingly connected to the _ seat 30, the expansion card baffle fixing device assembly, [0015] Please continue to refer to FIG. 4 to FIG. 5 'When the baffle 1 of the expansion card is to be fixed, the expansion card is installed In the computer case (not shown). The baffle 1 of the expansion card is mounted on the rear plate 20 of the computer case, so that the connecting portion U of the baffle 1 occludes the slot directly under the expansion card baffle fixing device, and the baffle of the baffle U The folded portion 14 is stuck to the bearing 21 of the rear plate 2G. Rotating the triggering portion 41 of the operating member 40 in the direction of the rear plate 20, the tips of the two abutting blocks 45 of the operating member 4 are respectively rotated in the grooves of the two pivoting portions 51 of the locking member 50. Abutting the corresponding abutting wall 516, thereby pushing the latching member 5 to rotate around the second pivoting shaft 512, the connecting portion 53 of the latching member 50 and the latching ring are turned away from the operating member 4Q (4). When the operation member moves to the position of the purely fixed seat 3 rigid plate 31, the two abutting blocks 45 respectively vertically abut against the abutting wall 516 of the two insertion portions 51, and the fastening member 5 The pressing portion 551 of the buckle 55 is reduced to the bending plate 14 and the locking portion 554 is locked to the connecting portion 12 of the playing board 1G, so that the shutter 10 is broken. At this time, the lever portion 4 is released, because the two abutting blocks seem to be vertically opposed to the two portions 51, 516, and the top end block 45 abuts against the tip end of the corresponding abutting wall 516 to the operating member. 4 (4) 柩 pivot 098113260 Form No. A0101 Page 8 / 18 pages 0992022141-0 201039098 [0016] ❹ [0018] [0020] [0020] The vertical lines of the lines are perpendicular to the two rotations 51, respectively. In the top wall, the direction of the force acting on the two abutting blocks 45 respectively points to the pivot axis of the operating member 40, and the two abutting blocks cannot be rotated. The latching member 50 and the operating member 40 are in a self-locking state. Referring again to FIG. 2 and FIG. 3, when the flapper of the expansion card is to be unlocked, the operating member 4 is rotated away from the rear panel 20. The two abutting blocks 45 of the operating member 40 rotate and respectively push the arc-shaped corners 515 of the two pivoting portions 51 of the latching member 5, the connecting portion 53 of the latching member 50 and the buckle The 55 is rotated away from the shutter 1 toward the operating member 4, and the shutter 1 is unlocked. Continuing to rotate the triggering portion 41, the tips of the two abutting blocks of the operating member 4 are respectively received in the recesses 514 of the two pivoting portions 51 of the latching member 50 and correspond to the abutment of the two recesses 514. The side wall of the curved corner 515 causes the latching member 50 to continue to rotate away from the baffle 10, thereby facilitating the removal of the baffle 10. In summary, the present invention complies with the requirements of the invention patent and submits a patent application according to law. However, the above description is only the preferred embodiment of the present invention, and equivalent modifications or variations made by those skilled in the art of the present invention should be included in the following claims.
