[0034] See also Figures 1 to 5, shown is a computer motherboard 30 fixing device in an embodiment of the present utility model, including a mounting plate 10, a connecting component 20, a clamping component 40 and a limiting component 50.

[0035] The connecting components 20 are provided in several groups, and several of the connecting components 20 are connected to the mounting plate 10, and the mounting plate 10 is connected to the computer motherboard 30 through the connecting components 20. The clamping components 40 are provided in several groups, and several of the clamping components 40 are arranged on the surface of the mounting plate 10 away from the computer motherboard 30. The clamping components 40 are provided with a clamping interface 43, and the clamping interface 43 is provided with a positioning bolt 44 adapted thereto. The limiting components 50 are provided in several groups, and several of the limiting components 50 are arranged on the surface of the mounting plate 10 corresponding to the clamping components 40, and are located on one side of the clamping components 40, wherein the positioning bolt 44 is arranged on the inner wall of the chassis (not shown in the figure) and is used to press against the clamping component 40 to press against the mounting plate 10, and the limiting component 50 is used to fix the positioning bolt 44 in the clamping interface 43.

[0036] It can be understood that the computer motherboard 30 is connected to the mounting plate 10 by a number of connecting components 20, thereby avoiding a short circuit caused by direct contact between the computer motherboard 30 and the inner wall of the chassis. The positioning bolts 44 are installed on the inner wall of the chassis, and the card interface 43 of the card assembly 40 on the mounting plate 10 is clamped on the positioning bolts 44 from top to bottom, so that the mounting plate 10 can be initially fixed on the inner wall of the chassis, and then the positioning bolts 44 in the card interface 43 are fixed by the limiting component 50, so that the mounting plate 10 can be stably set on the inner wall of the chassis, and then the computer motherboard 30 can be stably installed on the inner wall of the chassis.

[0037] Specifically, in this embodiment, several of the connecting components 20 include a connecting bolt 21, a limiting ring 22 and a nut 23. One end of the connecting bolt 21 passes through the mounting plate 10 and the computer motherboard 30 in sequence and is connected to the nut 23. The nut 2 is located on the upper surface of the computer motherboard 30, and the limiting ring 22 is arranged on the connecting bolt 21 and is located on the lower surface of the computer motherboard 30.

[0038] During the specific implementation, one end of the connecting bolt 21 first passes through the mounting plate 10, then the limiting ring 22 is placed on the connecting bolt 21, and one end of the connecting bolt 21 passes through the pre-set through-hole 45 of the computer motherboard 30. At this time, the limiting ring 22 is against the lower surface of the computer motherboard 30, and then the nut 23 is tightened on the top of the connecting bolt 21, that is, the upper surface of the computer motherboard 30. It is worth noting that the limiting ring 22, the nut 23 and the connecting bolt 21 are all made of plastic to avoid short circuit of the computer motherboard 30.

[0039] Specifically, in this embodiment, several of the snap-in components 40 include a snap-in plate 41 and a fixing pin 42. The snap-in plate 41 is arranged on the surface of the mounting plate 10 away from the computer motherboard 30. The snap-in plate 41 is fixed to the surface of the mounting plate 10 by the fixing pin 42. The card interface 43 is arranged at the bottom of the snap-in plate 41 and passes through the card interface 43. Through holes 45 are provided on both side walls of the snap-in plate 41. The through holes 45 are arranged on both sides of the card interface 43.

[0040] It can be understood that the card interface 43 at the bottom of the card plate 41 is placed on the positioning bolt 44 from top to bottom so that the positioning bolt 44 can be inserted into the card interface 43, thereby making the card plate 41 clamped on the positioning bolt 44 on the inner wall of the chassis, and then making the mounting plate 10 fixed together with the card plate 41 able to be set on the inner wall of the chassis, and the positioning screw can be fixed in the card interface 43 by passing through the through holes 45 on both sides of the card interface 43 through the limiting component 50.

[0041] Furthermore, the cross-section of the card interface 43 is a boss-shaped structure. It is understood that since one end of the positioning bolt 44 is provided with a screw head, the screw head portion can enter the interior of the card interface 43, while the screw portion of the positioning screw is provided outside the card interface 43, thereby making the positioning screw more stable when inserted into the card interface 43.

[0042] Specifically, in this embodiment, several of the limiting components 50 include a connecting block 51 and a sliding limiting rod 52. The connecting block 51 is fixed to the surface of the mounting plate 10 and is located on one side of the clamping component 40. A sliding groove 53 is provided on the connecting block 51. The sliding limiting rod 52 is slidably set in the sliding groove 53. One side wall of the sliding limiting rod 52 is a stepped structure.

[0043] It can be understood that the sliding limit rod 52 can slide in the slide groove 53 of the connecting block 51, and pass through the through holes 45 on both sides of the card interface 43 during the sliding process, so that the positioning bolt 44 in the card interface 43 can be fixed in the card interface 43. It is worth noting that in this embodiment, one side wall of the sliding limit rod 52 and an inner wall of the through hole 45 are both stepped structures, so that the screw head part and the screw rod part of the positioning bolt 44 can be fixed to improve the fixing quality.

[0044] In summary, the computer motherboard 30 fixing device in the above-mentioned embodiment of the present invention connects the computer motherboard 30 to the mounting plate 10 through a number of connecting components 20, thereby avoiding a short circuit caused by direct contact between the computer motherboard 30 and the inner wall of the chassis. The card interface 43 on the card connection component 40 is clamped on the positioning bolt 44 set on the inner wall of the chassis, so that the mounting plate 10 can be conveniently set on the inner wall of the chassis, and the positioning bolt 44 is limited in the card interface 43 by the limiting component 50, so that the mounting plate 10 can be stably set on the inner wall of the chassis, thereby achieving the purpose of convenient installation of the computer motherboard 30.
