[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments. Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Reference Figures 1-5 The present invention provides a specific embodiment of a novel multi-serial port card, comprising a motherboard 1, a guide rail 2 fixedly connected to one side of the upper end of the motherboard 1, a plurality of sliders 5 disposed inside the guide rail 2, a first spring 6 fixedly connected to both sides of the interior of the plurality of sliders 5, a connecting block 7 fixedly connected to the other end of the plurality of first springs 6, a limit plate 8 rotatably connected to one side end face of the plurality of connecting blocks 7, a plurality of housings 12 evenly spaced and fixedly connected to the upper end of the motherboard 1 near the guide rail 2, a second spring 13 fixedly connected to the upper and lower ends of the interior of the plurality of housings 12, a connecting plate 14 fixedly connected to the other end of the plurality of second springs 13, a limit rod 15 fixedly connected to the upper and lower ends of one side end face of the plurality of connecting plates 14, and a port clip 9 disposed at the upper end of the plurality of sliders 5;

[0030] The device uses a slider 5 to slide into the guide rail 2, a connecting block 7 to engage with the rectangular groove 3, and a limiting plate 8 to rotate and fit snugly against the side of the guide rail 2. Simultaneously, a second spring 13 pushes a limiting rod 15 into the limiting plate 8, securing the latch 9 firmly to the upper end of the main board 1. When the latch 9 is damaged or needs to be replaced, simply pull the lever 16 to slide the limiting plate 8 out of the limiting rod 15, rotate the limiting plate 8, and press it to disengage it from the rectangular groove 3. The latch 9 will then slide out of the guide rail 2 quickly and easily, requiring no complicated tools. This convenient insertion and removal operation improves work efficiency.

[0031] Rectangular grooves 3 are formed on both ends of multiple sliders 5, and multiple connecting blocks 7 are located inside the rectangular grooves 3. The end face of the limiting plate 8 set at one end of the multiple connecting blocks 7 is in close contact with the end face of the guide rail 2. The cooperation between the sliders 5 and the connecting blocks 7 can ensure that the latch 9 is stably positioned in the guide rail 2, which improves the stability and reliability of the device. The exterior of multiple limiting rods 15 is slidably connected to the housing 12, and one end of each limiting rod 15 extends into the interior of the limiting plate 8 on one side. The sliding connection between the limiting rods 15 and the housing 12 allows the limiting rods 15 to extend and retract freely as needed, ensuring that the limiting plate 8 can accurately control the fixing and releasing of the latch 9 under different working conditions. A pull rod is fixedly connected to the middle of one end face of multiple connecting plates 14. 16. The external parts of multiple pull rods 16 are slidably connected to the housing 12. The sliding connection of the pull rods 16 enables precise control of the limit rod 15, allowing users to operate the movement of the limit rod 15 more conveniently and reducing the complexity of operation. One end face of multiple port cards 9 is connected to wires 10, and the other end of multiple wires 10 is connected to an interface 11. The interface 11 is connected to the main board 1 through a plug. The design of the port card 9 and the wires 10 ensures stable transmission of signals or power, enabling the device to achieve smooth transmission of data or power during operation, improving the functionality and reliability of the overall system. A heat sink 4 is provided on the upper end of the main board 1. The heat sink 4 can effectively dissipate heat, prevent the main board 1 from overheating, and improve the long-term stability and service life of the device.

[0032] Working principle: First, slider 5 slides into guide rail 2 to form a precise fit. Then, connecting block 7 engages in rectangular groove 3 to effectively lock clip 9, ensuring that clip 9 does not shift or loosen during use. Next, the rotation of limiting plate 8 makes it fit tightly against the side of guide rail 2, further enhancing the stability. At the same time, the second spring 13 allows limiting rod 15 to extend into limiting plate 8, providing additional support for clip 9 and ensuring that clip 9 is firmly fixed on the upper part of main board 1, thus preventing clip 9 from loosening due to vibration or external interference during operation. When clip 9 needs to be replaced or removed, the user only needs to pull lever 16 to slide limiting plate 8 out from inside limiting rod 15. Subsequently, limiting plate 8 can be rotated and pressed, thereby disengaging it from rectangular groove 3. This process allows clip 9 to slide smoothly out of guide rail 2, completing disassembly quickly and easily without the use of any complicated tools. The whole process is efficient and convenient, greatly improving work efficiency.

[0033] 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 specific embodiments, those skilled in the art can still modify the technical solutions described in the foregoing specific 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.
