Description of the new type: [Technical field to which the new type belongs] Especially a convenient fixing and disassembly This creation is about an expansion card fixing device, an expansion card fixing device of an expansion card. [Previous technology] The conventional method of fixing the card is to directly __ fix it in the computer case. The mosquito method is extremely inconvenient for the assembly and disassembly of the expansion card. In recent years, various types of expansion card fixing devices have appeared in the industry, such as the expansion card fixing device disclosed in US Patent No. 5,3Π, 483, which uses a bead to fix a plurality of expansion card-fixed inserts to a computer base. On the window frame, when fixing the expansion cards, 'the end of the inscription can be installed on the green card, and the other end of the bead is turned downwards. When the bead reaches the top scale cutting At the same time, the other end of the bead is fixed to the window frame with a screw to fix the expansion cards. The above method is to remove the _required_secret_lang hand scale or _ strip of the fixed expansion card before you can ^ expand the card, which is not conducive to operation; and there is no pressure on the bottom of the strip. The structure is only fixed by the flat bottom surface The cuttings are not easy to insert, so that the cuttings are easy to loosen. Another example is the expansion card fixing wire disclosed in U.S. Patent No. 5,936,835, which includes-fixed trips, the fixed body includes-the body portion and-a plurality of buckle pieces vertically bent and extended from the body portion: the body portion opens a passage When fixing the expansion card, the clips can be inserted into the corresponding openings in the rear panel of the computer 'and abut the inserts fixed on the expansion card. At this time, the body of the fixed body is at the rear. On the outside of the board, the fixing body can be locked to the rear board by screwing through the through hole of the 唁 M260999 body part and the screw hole corresponding to the rear board, so as to fix the expansion card. In the above method, when fixing the expansion card, the fixing body needs to be removed from the computer back plate, which may easily lead to the loss of the fixing body. Therefore, it is necessary to improve the conventional expansion card fixing device to eliminate the above-mentioned defects. [New content] The purpose of this creation is to provide an expansion card fixing device that is convenient for fixing and removing expansion cards. _ This creative expansion card fixing device is used to fix a plurality of expansion cards with capture pieces in Zhenyi computer case, which includes a rear plate and a fixed body rotatable on the rear plate. An opening is provided at the fixed body. The fixed body includes a bottom wall and a rear wall. The bottom wall is provided with a plurality of elastic pressing portions corresponding to the blocking piece. A positioning hole is formed on the fixed body, and the rear plate corresponds to the positioning hole. A positioning portion is protruded. The advantage of this creation lies in the fact that the expansion board's retaining plate is fixed by a rotatable device on the fixed body on the rear panel to fix the expansion card. [Embodiment] € Please refer to the first figure. This creative expansion card fixing device is used to fix a plurality of expansion cards 30 in a computer case, which includes a base and a plurality of expansion cards 30 for fixing the expansion cards 30. The blocking piece 35 and a fixing body 40. The base includes a bottom plate 12 and a rear plate 14 extending vertically upward from the rear end of the bottom plate 12. The rear plate 14 has a rectangular opening 16 at the upper portion, and the rear plate 14 is bent inwardly on both sides of the opening 16. A fixing portion 18 is formed. Each fixing portion 18 is provided with a pivot hole 2G in the lower 6 M260999 portions, and a positioning portion 22 is protruded in the direction of each pivot hole 2Q. The rear plate 14 * bu part is further formed above the system σ 16-shallower depression (not shown) 'The depression is provided inwardly-a stud% with a locking hole (not labeled in the figure). The rear plate 14 is further fixed with a fixed seat below the opening 16. The fixed seat 25 includes a straight wall 26 and a bent wall π formed by bending the upper end of the straight wall 26. The upright niches are provided with a plurality of parallel long grooves 28 at intervals. The long grooves 28 also extend to the bent wall 27. The bent wall 26 is provided with a protrusion 29 corresponding to each vertical wall. The bottom plate 12 is fixed to a main board 80, and there are no multiple slots 82 perpendicular to the back plate 14. The shape of the blocking piece 35 corresponds to the long groove 28 of the fixing base 24 and includes a body portion 36 and a bending portion 37 bent vertically from one end of the body portion 36. The expansion cards 30 are respectively fixed to the On the main body part of the broadcast film 35, a socket part 38 corresponding to the slot 82 of the main board 80 is provided, and the bending part 37 corresponds to the protrusion 29 of the rear plate 14 and has a notch 39 on one side. Referring to the second figure together, the fixed body 40 has a hollow triangular shape, and includes a bottom wall 42, a front wall 44, and a rear wall 46. The rear wall 46 intersects the front wall 44. Continue to extend upwards and bend forward on both sides to form a mounting portion 50, a locking portion 48 is formed at the end, a locking hole 56 is opened in the middle of the locking portion 48, and the mounting portion 50 pairs An annular pivoting portion 52 is protruded from the pivoting hole 20 of the rear plate 14, and a positioning hole 54 is opened above the pivoting portion 52 corresponding to the positioning portion 22 of the rear plate 16. The bottom wall 42 has an opening (not shown) corresponding to each of the stretchers 35, and an elastic pressing portion 58 is formed at the rear end of the opening and extending into the opening respectively. The bottom wall 42 and the front wall 44 are formed at the boundary corresponding to the protrusions 29 of the rear plate 14 to form a plurality of avoidance holes 60. 7 M260999 Please refer to the third and fourth figures. When assembling, first fix the fixing body 40 from the base to the rear panel 14 and then install the expansion card 30. The pivoting portion 52 of the fixing body 40 is accommodated in the pivoting hole 20 of the fixing portion 18 of the rear plate 14. The Guding body 4G can be rotated and installed by riveting or side-bending. On the back plate 14. When installing the expansion card 30, the fixed body 40 is rotated out of the base from the opening 16 of the rear plate 14, so that the bottom wall 42 of the fixed body 40 is separated from the reading wall 27 of the fixed seat 25 of the rear plate 14. . Then make the plug-in part of the expansion card 30 into the slot 82 of the corresponding motherboard 80%, and the body part of the perch piece 35 is located on the rear plate 14 fixed. The seat 25 and the straight wall 26 And the corresponding long groove 28 is covered, and the bent portion is placed on the bent wall 27 of the fixed seat 24, and the protrusion 29 of the f-folded portion π is accommodated in the missing σ 39 of the sheet 35 . The fixed body 40 is rotated from the base part toward the inside, the elastic pressing part 58 of the fixed body 40 is pressed against the bent part 37 of the blocking piece 35, and the locking 48 valley of the fixed body 40 is placed in the In the recess on the outside of the rear plate 14, at the same time, the positioning portion 22 of the fixing portion 18 of the rear plate 14 is accommodated in the positioning hole% of the fixing body 40. At this time, the fixing body 40 is fixed to the rear plate. 14 to fix the expansion card 30. In order to achieve more stability of the fixing body 40, a locking screw 56 of the fixing body 40 and a stud 24 of the rear plate 14 may be provided by a manual screw to achieve better fixing of the fixing body 40. On the rear plate 14. The avoidance hole 60 can receive the protrusion 4 of the rear plate 14. When disassembling the expansion card 30, only f remove the hand _wire 90, _ rotate the fixed body 40 to the outside of the base, and the bottom wall 42 of the expansion board 30 is separated from the bent wall of the rear plate 14, and at this time, can be removed Replace the corresponding expansion card 30. 8 M260999 [Schematic description] The first picture is an exploded perspective view of the expansion card fixing device and the expansion card of this creation.
