The motherboard is a large circuit board used to connect and manage all hardware devices, including the central processing unit, memory, storage devices, graphics card, power supply and other peripheral devices, to ensure that these hardware devices can work together. The motherboard is the carrier of all computer components and the foundation of the entire internal structure of the computer, playing a crucial role in the computer.

[0003] In existing technology, the motherboard is one of the indispensable hardware components in a computer. The motherboard not only connects multiple hardware components together, but also provides power to hardware such as the central processing unit, memory, and storage devices. Generally, when the motherboard is connected to the mounting plate in the chassis, it is usually connected with bolts to securely attach the motherboard inside the chassis. However, using bolts to connect the motherboard is not only cumbersome, but also prone to stripping when turning the bolts, making it impossible to tighten them smoothly. Furthermore, if the bolts are damaged or broken, it can easily prevent the motherboard from being easily removed from the chassis or from being installed stably. Utility Model Content

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0026] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0027] This application discloses a motherboard mounting device. (Refer to...) Figure 1 and Figure 8 A motherboard fixing device includes a chassis 1 and a motherboard body 3. A fixing plate 2 is fixedly connected to the inner cavity of the chassis 1. One side of the motherboard body 3 is movably inserted into one side of the fixing plate 2. A fixing mechanism 4 is provided on one side of the fixing plate 2.

[0028] The fixing mechanism 4 includes a fixing block 401. One side of the fixing block 401 is fixedly connected to one side of the fixing plate 2. A hollow groove 409 is opened on one side of the fixing plate 2. An mounting ring block 402 is fixedly connected to one side of the main body 3. A first arc-shaped block 403 and a first buckle 404 are fixedly connected to the surface of the mounting ring block 402. The surface of the mounting ring block 402 is movably inserted into the inner cavity of the hollow groove 409. A rotating rod 405 is rotatably connected to the inner cavity of the fixing block 401. A rotating ring block 406 is fixedly connected to one end of the rotating rod 405. A second arc-shaped block 407 and a second buckle 408 are fixedly connected to the surface of the rotating ring block 406.

[0029] The chassis 1 can connect the motherboard body 3 to one side of the fixing plate 2 via the fixing mechanism 4, allowing the motherboard body 3 to be installed and used smoothly. The fixing plate 2 can install and fix the fixing block 401, and the fixing block 401 can be connected to the rotating ring block 406 via the rotating rod 405. The rotating ring block 406 can install and fix the second arc-shaped block 407 and the second clip 408. At the same time, the motherboard body 3 can be connected and installed to the first arc-shaped block 403 and the first clip 404 via the mounting ring block 402. The first clip 404 and the second clip 408 are the same size. 403 is the same size as the second arc-shaped block 407. When the rotating rod 405 drives the rotating ring block 406 to rotate, it can drive the second arc-shaped block 407 and the second buckle 408 to rotate together. When the second arc-shaped block 407 and the second buckle 408 rotate to a certain angle, the second arc-shaped block 407 will be inserted into the inside of the first buckle 404, while the second buckle 408 can rotate to the surface of the first arc-shaped block 403, thereby realizing the connection between the rotating ring block 406 and the mounting ring block 402. At this time, the installation and connection between the fixing plate 2 and the main body 3 can be completed, thereby improving the convenience of the fixing plate 2 and the main body 3 when they are connected to each other.

[0030] Reference Figure 6 and Figure 7 A limiting groove 11 is fixedly connected to one side of the rotating ring block 406, and a limiting ring block 10 is provided on one side of the mounting ring block 402. One side of the limiting groove 11 is rotatably connected to the inner cavity of the limiting ring block 10. When the rotating ring block 406 is in contact with the mounting ring block 402, the limiting ring block 10 and the limiting groove 11 will be connected. The limiting groove 11 can increase the stability and stability of the rotating ring block 406 and the mounting ring block 402 when they are connected by the connection between itself and the limiting ring block 10.

[0031] Reference Figure 5 and Figure 6 A pull rod 6 is slidably connected to the inner cavity of the fixed block 401. A toothed block 7 is fixedly connected to one end of the pull rod 6. A gear 5 is fixedly connected to the surface of the rotating rod 405. The surface of the toothed block 7 meshes with the teeth of the gear 5. The fixed block 401 can install and fix the toothed block 7 through the pull rod 6. When the toothed block 7 meshes with the gear 5, it can limit the gear 5 and the rotating rod 405. This allows the rotating rod 405 to be effectively and stably limited when the rotating ring block 406 does not need to be rotated, reducing the possibility of the rotating rod 405 and the rotating ring block 406 rotating.

[0032] Reference Figure 5 and Figure 6A mounting plate 8 is fixedly connected to the surface of the pull rod 6, and a spring 9 is fixedly connected to the top of the mounting plate 8. One end of the spring 9 is fixedly connected to the inner cavity of the fixing block 401. The surface of the spring 9 is sleeved on the surface of the pull rod 6. The mounting plate 8 and the fixing block 401 cooperate with each other to install and fix the spring 9. The spring 9 can push the mounting plate 8 and the pull rod 6 through its own elasticity, so that the tooth block 7 can be more effectively and stably locked on the surface of the gear 5. When the operator pulls the pull rod 6, the pull rod 6 and the tooth block 7 can be reset more smoothly and quickly, which increases the convenience of the pull rod 6 in use.

[0033] Reference Figure 3 and Figure 4 A reinforcing plate 15 is fixedly connected to one side of the motherboard body 3. A mounting slot 16 is provided on one side of the fixing plate 2. The surface of the reinforcing plate 15 is movably inserted into the inner cavity of the mounting slot 16. When the motherboard body 3 is connected to the fixing plate 2 through the fixing mechanism 4, the reinforcing plate 15 will also be smoothly inserted into the inside of the mounting slot 16. The mutual connection between the reinforcing plate 15 and the mounting slot 16 can not only increase the stability of the motherboard body 3 after it is connected to the fixing plate 2, but the reinforcing plate 15 can also provide a certain support and fixation for the motherboard body 3 through the mounting slot 16, so that the motherboard body 3 can be used stably and is not easy to shake, tilt or fall during use.

[0034] Reference Figure 2 and Figure 3 A connecting block 17 is fixedly connected to one side of the fixed plate 2. A sliding rod 18 is slidably connected to the inner cavity of the connecting block 17. A limiting block 19 is fixedly connected to one end of the sliding rod 18. The top of the limiting block 19 is movably inserted into the inner cavity of the reinforcing plate 15. The connecting block 17 can install and connect the limiting block 19 through the sliding rod 18. After the reinforcing plate 15 is inserted into the mounting slot 16, the limiting block 19 can be inserted into the reinforcing plate 15 by moving upward. The connection between the limiting block 19 and the reinforcing plate 15 can not only further improve the stability of the reinforcing plate 15 and the main board body 3 during use, but also further enhance the support effect of the reinforcing plate 15 on the main board body 3.

[0035] Reference Figure 6 and Figure 7A slot 14 is provided on one side of the rotating rod 405. A plug block 13 is movably inserted into the inner cavity of the slot 14. A rotating block 12 is fixedly connected to one side of the plug block 13. The rotating block 12 can drive the rotating rod 405 to rotate together when it rotates through the movable connection between the plug block 13 and the slot 14. The setting of the rotating block 12 and the plug block 13 makes it more convenient and easy for the staff to rotate the rotating rod 405. At the same time, the plug block 13 and the rotating block 12 can be stored separately when not in use. When in use, the slot 14 can be reinforced to connect with the plug block 13. This makes it less likely that the chassis 1 will not be unable to close smoothly due to the setting of the rotating block 12, or that the internal volume needs to be expanded.

[0036] Working Principle: When using this device, the operator can move one side of the motherboard body 3 towards the side of the fixing plate 2. During this movement, the reinforcing plate 15 needs to be inserted into the mounting slot 16. Once the reinforcing plate 15 is inserted into the mounting slot 16, the connection between the reinforcing plate 15 and the mounting slot 16 not only provides support and connection for the motherboard body 3 but also provides positioning. Simultaneously, because the fixing plate 2 is in contact with the motherboard body 3, the mounting ring block 402 will also be in contact with the rotating ring block 406. At this point, the operator can pull the lever 6, causing the lever 6 to move the toothed block 7 upwards, thus removing the restriction of the toothed block 7 on the gear 5. While pulling the lever 6, the insert block 13 is inserted into the slot 14. After insertion, the rotating block 12 is rotated. The rotation of the rotating block 12 will cause the second arc-shaped block 407 and the second latch 408 to rotate together via the rotating rod 405 and the rotating ring block 406. After rotating to a certain angle, the second arc-shaped block 407 will insert... The first latch 404 is inserted into the first latch 404, while the second latch 408 rotates to the surface of the first arc-shaped block 403. At this point, the connection between the second arc-shaped block 407 and the first latch 404, and between the second latch 408 and the first arc-shaped block 403, connects the rotating ring block 406 and the mounting ring block 402. Simultaneously, the limiting groove 11 connects with the limiting ring block 10, increasing the stability of the connection between the rotating ring block 406 and the mounting ring block 402. Finally, the limiting block 19 is moved through the slide rod. 18 moves upward, and after the slide bar 18 and the limiting block 19 move upward to a certain distance, the limiting block 19 will be inserted into the interior of the reinforcing plate 15, thereby fixing and connecting the motherboard body 3 and the fixing plate 2. When it is necessary to disassemble the motherboard body 3, simply pull the limiting block 19 out of the interior of the reinforcing plate 15, and while pulling the pull rod 6, rotate the rotating rod 405 in the opposite direction to cancel the connection between the mounting ring block 402 and the rotating ring block 406, thereby achieving the disassembly of the motherboard body 3 and the fixing plate 2.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
