[0002] The computer motherboard fixture is one of the indispensable parts in the computer hardware assembly process. It is mainly used to fix the computer motherboard to ensure that the motherboard is stably placed in the chassis to prevent the motherboard from being damaged due to vibration or other reasons during use. The computer motherboard fixture has the characteristics of simple structure, easy installation, strong compatibility, good shockproof performance, etc. It is an ideal choice in the computer hardware assembly process.

[0003] The traditional way to fix the motherboard is to first place the motherboard flat on the mounting bracket of the chassis, making sure that the contact surface between the motherboard and the bracket is flat. There will be multiple screw holes on the motherboard for fixing, which are usually located on the edge of the motherboard. Align the motherboard with the screw holes inside the chassis, make sure that the motherboard is in the correct position, and use screws to fix the motherboard to the bracket of the chassis through the screw holes on the motherboard. Usually, screws are fixed at the four corners or other key points of the motherboard.

[0004] Traditional motherboard mounting methods may limit the motherboard's installation position, especially for large or special-shaped motherboards. The fixings may hinder the air flow inside the chassis, affecting the heat dissipation effect. If the design of the motherboard or chassis changes, the traditional fixing method may be difficult to adapt to the new motherboard specifications, which will hinder the upgrade or replacement of the motherboard.

[0025] Specifically, the slider 6 is made to slide above the fixed slide rail 5 by rotating the first knob 4, and the clamping block 8 pushes the first sliding block 9, the second sliding block 11 and the third sliding block 12 to be squeezed and slid inside the shell 7 by the extrusion force generated when the mainboard is squeezed and clamped. By setting a fixed cylinder 10, a limit block 13 with a surplus and opening a slot hole inside the shell 7, the first sliding block 9, the second sliding block 11 and the third sliding block 12 can have a surplus when sliding, and the baffle 3 and the clamping block 8 are used to achieve flexible clamping of the mainboard.

[0026] Reference Figure 2 - Figure 4 The sliding assembly includes a second support frame 14, the lower surface of the second support frame 14 is fixedly connected to the upper surface of the base plate 1, the second support frame 14 is slidably connected with a fixed clamping plate 21 inside, one end of the fixed clamping plate 21 is slidably connected with a fixed block 23, the second support frame 14 is rotatably connected with a second knob 15 inside, one end of the second knob 15 is fixedly connected with a first connecting plate 16, the lower surface of the first connecting plate 16 is rotatably connected with a second connecting plate 17, one end of the second connecting plate 17 is rotatably connected with a sliding plate 18, and the lower end of the sliding plate 18 is fixedly connected with a movable clamping plate 20, both ends of the movable clamping plate 20 are fixed to the outer wall of the fixed clamping plate 21, and the inside of the sliding plate 18 is slidably connected with a supporting rail 19, both ends of the supporting rail 19 are fixedly connected to the upper surface of the base plate 1, the lower surface of the fixed block 23 is fixedly connected to the upper surface of the base plate 1, and the lower part of the fixed clamping plate 21 is slidably connected to the upper part of the base plate 1.

[0027] Specifically, by rotating the second knob 15, the first connecting plate 16 is pushed backward and the second connecting plates 17 on both sides are driven to move inward. The inward movement of the second connecting plates 17 drives the sliding plate 18 to slide above the supporting rail 19, causing the fixed clamping plates 21 and the movable clamping plates 20 on both sides to move inward.

[0028] Reference Figure 1 - Figure 3 A baffle 3 is slidably connected to the interior of the bottom plate 1 , and a heat dissipation fan 22 is fixedly connected to the interior of the bottom plate 1 .

[0029] Specifically, by installing the cooling fan 22, the temperature of the mainboard during operation can be reduced, thereby achieving a heat dissipation effect.

[0030] Working principle: When a computer motherboard fixing device is needed, first, the first knob 4 is turned to push the housing 7 to slide on the top of the fixed slide rail 5 through the slider 6. The clamping block 8 pushes the first sliding block 9, the second sliding block 11 and the third sliding block 12 to slide inside the housing 7 through the extrusion force generated when the motherboard is squeezed and clamped. By setting a fixed cylinder 10, a limit block 13 with a surplus and opening a slot in the housing 7, the first sliding block 9, the second sliding block 11 and the third sliding block 12 can have a surplus when sliding, and the baffle 3 is used to prevent the first sliding block 9, the second sliding block 11 and the third sliding block 12 from sliding. The clamping block 8 realizes flexible clamping of the mainboard, thereby achieving the effect of fixing and protecting mainboards of different specifications. By turning the second knob 15, the first connecting plate 16 is pushed to move backward and the second connecting plates 17 on both sides are driven to move inward. The inward movement of the second connecting plate 17 drives the sliding plate 18 to slide above the supporting rail 19 to make the fixed clamping plates 21 on both sides move inward, thereby achieving the effect of fixing and clamping the mainboard. When the mainboard is working, the temperature of the mainboard can be reduced by adding a cooling fan 22, which plays a role in heat dissipation and improves the working efficiency of the mainboard.
