[0025] In order to better understand the purpose, structure and function of the present invention, the following is a further detailed description of a computer motherboard fixing device for a computer of the present invention in conjunction with the accompanying drawings.

[0026] See also Figure 1-4 The utility model discloses a computer motherboard fixing device for a computer, comprising a bottom plate 1, four dampers 2 are fixedly connected to the upper surface of the bottom plate 1, a support plate 3 is fixedly connected to the tops of the four dampers 2, two mounting plates 14 are fixedly connected to the left and right sides of the bottom plate 1, and two mounting holes 15 are provided on the upper surface of each mounting plate 14. By relying on the cooperation between the mounting plates 14 and the mounting holes 15, the convenience of fixing the bottom plate 1 can be improved. The mounting plates 14 and the bottom plate 1 can be fixed by passing foreign objects through the mounting holes 15, which increases the convenience of the device during installation.

[0027] An auxiliary spring 4 is sleeved on the outside of each damper 2, the top end of each auxiliary spring 4 is fixedly connected to the bottom surface of the support plate 3, the bottom end of each auxiliary spring 4 is fixedly connected to the upper surface of the base plate 1, and a reinforcement block 16 is fixedly connected to the upper surface of each mounting plate 14. The side surfaces of the two groups of reinforcement blocks 16 close to each other are respectively fixedly connected to the left and right side surfaces of the base plate 1. The reinforcement blocks 16 can increase the fixed connection area between the mounting plate 14 and the base plate 1, making the connection between the two parties more secure, thereby preventing the mounting plate 14 from breaking or loosening after long-term use, thereby causing the base plate 1 to fall off.

[0028] A connecting plate 5 is fixedly connected to the inner wall of the base plate 1, and two exhaust fans 6 are fixedly connected to the inner wall of the connecting plate 5. Two fixing blocks 17 are fixedly connected to the front and back sides of the connecting plate 5. The side faces of each group of fixing blocks 17 that are away from each other are fixedly connected to the inner wall of the base plate 1. The fixing blocks 17 can improve the fixed connection relationship between the connecting plate 5 and the base plate 1, improve the firmness of the connection between the two parties, prevent the connecting plate 5 from cracking due to long-term use, and increase the durability of the device.

[0029] Two groups of auxiliary blocks 7 are fixedly connected to the upper surface of the support plate 3, and the interior of each group of auxiliary blocks 7 is rotatably connected with a bidirectional threaded rod 8. The outer surface of each bidirectional threaded rod 8 is sleeved with two auxiliary bearings 18, and each auxiliary bearing 18 is embedded in the interior of the auxiliary block 7. The auxiliary bearings 18 can reduce the friction generated by the bidirectional threaded rod 8 during rotation, making the bidirectional threaded rod 8 more sensitive during rotation. At the same time, it can also reduce the wear rate of the bidirectional threaded rod 8 and increase the service life of the bidirectional threaded rod 8.

[0030] The outer surface of each bidirectional threaded rod 8 is threadedly connected to two moving plates 9, and each group of moving plates 9 is slidably connected to the inside of the auxiliary block 7. The two groups of moving plates 9 are fixedly connected to a stabilizing block 19 on the side away from each other, and each stabilizing block 19 is slidably connected to the inside of the auxiliary block 7. The stabilizing block 19 can move simultaneously with the moving plate 9, and rely on its own friction with the auxiliary block 7 during the movement to increase the force point of the moving plate 9 when moving, thereby effectively improving the stability of the moving plate 9 when moving.

[0031] The side of each group of movable plates 9 that are close to each other is fixedly connected to an outer sleeve 10, and the interior of each outer sleeve 10 is slidably connected to an inner sleeve 11, and the end of each group of inner sleeves 11 that is away from each other is fixedly connected to a pressure spring 12, and the end of each group of pressure springs 12 that is away from each other is fixedly connected to the inner side wall of the outer sleeve 10, and the end of each group of inner sleeves 11 that are close to each other is commonly fixedly connected to a clamping plate 13, and the outer surface of each inner sleeve 11 is fixedly connected to a reinforcement ring 20, and the ends of the two groups of reinforcement rings 20 that are close to each other are fixedly connected to the side of the clamping plate 13 that is away from each other. The reinforcement ring 20 can increase the fixed connection area between the inner sleeve 11 and the clamping plate 13, making the connection between the two parties more firm, and preventing the inner sleeve 11 from loosening with the clamping plate 13 due to long-term use.

[0032] The outer surface of each bidirectional threaded rod 8 is fixedly connected with a turning handle 21, and the side of each group of clamping plates 13 close to each other is fixedly connected with a rubber pad 22. The turning handle 21 can provide a good force point for the bidirectional threaded rod 8, increasing the convenience of rotating the bidirectional threaded rod 8 when needed. At the same time, the rubber pad 22 can reduce the damage caused by the clamping plate 13 when clamping the mainboard.

[0033] The working principle of the utility model is as follows: first, the device is fixed inside the host through the mounting plate 14 and the mounting hole 15. When the mainboard needs to be clamped or disassembled, the mainboard is placed on the upper surface of the connecting plate 5, and then the two turning handles 21 are respectively rotated to make the bidirectional threaded rod 8 rotate forward or reversely. The auxiliary bearing 18 can increase the sensitivity of the bidirectional threaded rod 8 when rotating, so that the moving plate 9 drives the clamping plates 13 to move closer to or away from each other. The stabilizing block 19 can improve the stability of the moving plate 9 when moving, and the rubber pad 22 can reduce the damage caused by clamping, so as to clamp and disassemble the mainboard. At the same time, when the clamping plate 13 is in continuous contact with the mainboard, the pressure spring 12 can be kept in contact with the mainboard. The same pressure drives the inner sleeve 11 to retract into the outer sleeve 10. The current clamping pressure can be determined by observing the inner sleeve 11 and the outer sleeve 10. It can stop when the appropriate force is reached. The motherboard can be clamped conveniently. At the same time, the force can be reasonably controlled during the clamping process to avoid damage to the motherboard caused by excessive clamping force. When the chassis shakes, the vibration force can be resolved by the damping effect generated by the damper 2 and the expansion and contraction ability of the auxiliary spring 4 to avoid damage to the motherboard caused by shaking of the host. At the same time, the exhaust fan 6 can effectively absorb the heat generated by the motherboard, effectively improving the applicability of the computer motherboard fixing device for the computer.
