Description

Technical Field

[0001] This utility model relates to the field of computer hardware technology, and in particular to a PCIe adapter board fixing structure. Background Technology

[0002] With the development of computer hardware technology, PCIe adapter boards, as key components for expanding PCIe device interfaces and improving system scalability, are widely used in consumer PCs, industrial equipment, and servers. The mounting structure of PCIe adapter boards directly affects the ease of device installation, operational stability, and hardware lifespan. Especially in scenarios involving multi-card expansion, adaptation to irregularly shaped chassis, or high-frequency maintenance, achieving flexible adaptation and reliable fixation between the adapter board and the chassis mounting position has become an important technical direction for improving the overall performance of hardware systems.

[0003] In existing technologies, the fixing structure of PCIe adapter boards mostly adopts traditional mechanical connection methods, such as fixed brackets with screw fastening, single buckle positioning, etc. These structures are usually based on standardized mounting position design, and the connection is achieved by aligning the fixing holes with the pre-set interface of the chassis. The technical principle relies on the rigid fit of the mechanical structure, and mainly provides support and limiting functions through physical contact. For example, some fixing brackets use "L" shaped metal plates with standard spacing screw holes, or use injection-molded plastic buckles to engage with the chassis slots to achieve vertical fixing of the adapter board.

[0004] However, existing technologies have significant drawbacks: due to the lack of adaptive adjustment capabilities for expansion card size and mounting slot spacing in the fixing structure, when faced with non-standard chassis mounting slots or expansion cards of different specifications, the adapter board often cannot be accurately installed due to hole position deviations. If forcibly fixed, it is very easy to cause hard physical stress between the PCIe adapter card and the motherboard slot, which in turn leads to problems such as bending of the graphics card PCIe slot pins and breakage of the motherboard slot clips, seriously affecting hardware reliability and lifespan. Moreover, such damage is usually irreversible and requires replacement of core components for repair, significantly increasing the cost of use and maintenance difficulty. Therefore, a PCIe adapter board fixing structure is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a PCIE adapter board fixing structure, which aims to improve the traditional structure's lack of adaptive adjustment function for adapter board size and mounting position spacing, resulting in inaccurate installation when facing non-standard mounting hole positions.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a PCIE adapter board fixing structure, including a housing, a buckle fixedly connected to the lower surface of the housing, a slide rail opened inside the housing, an expansion card slidably connected inside the slide rail, a support block slidably connected to the outer wall of the housing, a stop block fixedly connected to the outer wall of the support block, and a fixing component slidably connected to the outer wall of the support block;

[0007] The fixing component includes a fixing block, the inner wall of which is slidably connected to the outer wall of the support block, and the inner wall of the fixing block is fixedly connected to the outer wall of the expansion card. The fixing block is internally threaded with three bolts.

[0008] Furthermore, the expansion card is internally threaded with a second bolt, and the outer wall of the second bolt is threaded with a second nut. The support block is internally threaded with a first bolt, and the outer wall of the first bolt is threaded with a first nut.

[0009] Furthermore, a positioning groove is provided inside the outer shell, the second bolt passes through the expansion card and the positioning groove, and the first bolt passes through the support block and the positioning groove.

[0010] Furthermore, the outer wall of nut one abuts against the outer wall of the support block, and the outer wall of nut two abuts against the outer wall of the outer casing.

[0011] Furthermore, the housing is provided with heat dissipation holes to accelerate the dissipation of the temperature generated during the operation of the expansion card and prevent hardware failures caused by heat accumulation.

[0012] Furthermore, the support block has multiple positioning holes inside, which are used to accommodate bolts.

[0013] Furthermore, the outer wall of the expansion card is slidably connected to the outer wall of the outer casing.

[0014] Furthermore, the bolt passes through the fixing block and is threaded into the positioning hole.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the support block and the outer shell are slidably connected, and the fixing block is slidably connected to the outer wall of the support block. The fixing block is fixed by three bolts. Both the support block and the fixing block can be flexibly adjusted according to the size of the adapter card, so that the PCIE adapter board can be adapted to different installation positions, which significantly improves the compatibility, flexibility and applicable scenarios of the PCIE adapter board. The support block is provided with multiple limiting grooves, which further improves the practicality of the device.

[0017] 2. In this utility model, the PCIE adapter board is fixed by bolt one and nut one support frame, and then fixed by bolt three fixing blocks, which can achieve the effect of fixing the PCIE adapter board, thereby enhancing the stability of the adapter board and avoiding the possibility of the motherboard PCIE slot pins bending or even the motherboard slot clip breaking due to the loosening of the adapter card, thus improving the practicality of the device.

[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 protection scope of the present utility model.

[0026] Reference Figure 1 - Figure 5This utility model provides an embodiment of a PCIe adapter board fixing structure, including a housing 1. A buckle 2 is fixedly connected to the lower surface of the housing 1. The buckle 2 is used to precisely position and forcibly lock the housing 1 to the motherboard to ensure reliable electrical connection. A slide rail 12 is provided inside the housing 1. The slide rail 12 is used to allow the expansion card 5 to slide on the inner wall of the housing 1, so that the expansion card 5 can be adapted to different installation positions. The expansion card 5 is slidably connected inside the slide rail 12. A support block 10 is slidably connected to the outer wall of the housing 1. The support block 10 is used to cooperate with the fixing block 15 to fix the expansion card 5. A stop block 9 is fixedly connected to the outer wall of the support block 10 to prevent the fixing block 15 from slipping off the outer wall of the support block 10. The device is connected to a fixing component, which includes a fixing block 15. The inner wall of the fixing block 15 is slidably connected to the outer wall of the support block 10, and the inner wall of the fixing block 15 is fixedly connected to the outer wall of the expansion card 5. The fixing block 15 is threaded with a bolt 8, which works with the positioning hole 11 to achieve the effect of fixing the fixing block 15 to the support block 10 after the fixing block 15 is adjusted to the correct position. The outer shell 1 has a heat dissipation hole 4, which is used to accelerate the dissipation of the temperature generated by the expansion card 5 during operation and prevent hardware failure caused by heat accumulation. The support block 10 has multiple positioning holes 11, which are used to accommodate the bolts 8. The outer wall of the expansion card 5 is slidably connected to the outer wall of the outer shell 1, and the bolts 8 pass through the fixing block 15 and are threadedly connected to the inside of the positioning hole 11.

[0027] Reference Figure 1 - Figure 5 The expansion card 5 is internally threaded with bolt 2 7, which works with nut 2 14 to fix the expansion card 5 to the outer shell 1. The outer wall of bolt 2 7 is threaded with nut 2 14. The support block 10 is internally threaded with bolt 1 6, which works with nut 1 3 to fix the support block 10 to the outer shell 1. The outer wall of bolt 1 6 is threaded with nut 1 3. The outer shell 1 has a positioning groove 13 inside, which allows bolt 1 6 and bolt 2 7 to pass through the outer shell 1 for fixation. Bolt 2 7 passes through the expansion card 5 and the positioning groove 13, and bolt 1 6 passes through the support block 10 and the positioning groove 13. The outer wall of nut 1 3 abuts against the outer wall of the support block 10, and the outer wall of nut 2 14 abuts against the outer wall of the outer shell 1.

[0028] Working principle: When the PCIe adapter board needs to be used to fix the structure, firstly, the expansion card 5 is placed inside the slide rail 12, then the bolt 2 7 is passed through the expansion card 5 and the outer shell 1, and the nut 2 14 is put into the bolt 2 7 to achieve the effect of initially fixing the expansion card 5. At this time, the support block 10 can be adjusted by sliding on the outer wall of the outer shell 1. Then, the fixing block 15 is clipped on the outer wall of the expansion card 5. Since the fixing block 15 can slide on the outer wall of the support block 10, the fixing block 15 can be adjusted according to the size of the expansion card 5. Then, the bolt 3 8 is passed through the fixing block 15 and the support block 10 to fix the fixing block 15, thereby achieving the effect of fixing the expansion card 5. Then, the bolt 1 6 is passed through the positioning groove 13, and the nut 1 3 is put into the bolt 1 6 to fix the support block 10 on the outer wall of the outer shell 1. Therefore, it is possible to achieve the effect of multi-directional adjustment for PCIe adapter boards of different sizes, thereby achieving a better fixing effect for the expansion card 5. When the spacing of the PCIe slot mounting positions inside the chassis varies due to different design standards, simply slide the expansion card 5 within the slide rail 12. Once adjusted to the desired position, use bolt 7 and nut 14 to secure the expansion card 5 to the outer casing 1. Then, adjust and fix the support block 10 and fixing block 15 using the same method to achieve flexible adjustment based on the spacing of the mounting positions inside the chassis. After the expansion card 5 is adjusted and fixed, insert the clip 2 into the corresponding slot inside the chassis and insert the pins of the expansion card 5 into the PCIe slot on the motherboard. Ensure it is firmly inserted to use the PCIe adapter board.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
