Description

Technical Field

[0001] This utility model is a server cooling fan fixing device, belonging to the field of server technology. Background Technology

[0002] In the server assembly process, the cooling fan is a core component ensuring stable equipment operation. It is secured to a pre-set mounting position on the chassis using multiple sets of screws. The screw threads tighten to restrict the relative position of the fan and chassis, ensuring the cooling fan operates without vibration or displacement, and maintaining the stability of the cooling airflow. This screw-fixing method is the mainstream choice for server cooling fan installation due to its secure connection and high reliability. During installation, the cooling fan must first be aligned with the mounting holes on the chassis, ensuring the threaded holes on the fan are precisely aligned with the through holes on the chassis. Then, the screws are passed through the through holes and tightened into the threaded holes. Because the cooling fan itself has a certain weight, and the chassis mounting positions are often suspended or lack temporary support structures, the worker must use one hand to support and stabilize the cooling fan throughout the process, maintaining alignment between the fan and the mounting holes on the chassis at all times, while the other hand uses a tool to tighten the screws.

[0003] When operating tools with one hand, it's not only difficult to precisely control the screw-in angle, but also requires overcoming the risk of hole misalignment caused by the weight of the cooling fan. This makes it difficult for the screw to pass smoothly through the small hole and align with the threaded hole, often requiring repeated adjustments to complete the connection. Furthermore, holding the cooling fan with one hand for extended periods can cause arm fatigue, further affecting operational stability. This not only prolongs the assembly time of a single server and reduces overall production efficiency, but also risks stripping screws and damaging the cooling fan's threaded hole due to improper operation, increasing assembly costs and quality risks. This installation method, relying on manual two-handed coordination, is particularly inconvenient in batch assembly scenarios, becoming one of the key factors restricting server assembly efficiency. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a server cooling fan fixing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a server cooling fan mounting device, comprising: The chassis has a connector port on one side, and two sets of exhaust fans are machined on the side of the chassis with the connector port. The cooling fan is provided in two sets, which are respectively installed inside the two sets of exhaust fans. The cooling fan is connected to the chassis by multiple sets of screws. The connecting plate has two positioning sleeves installed on one side, and the two positioning sleeves are respectively fitted onto two cooling fans. One end of the connecting plate is equipped with a plug plate, which passes through the connector. The upper surface of the plug plate has a slot, which is located on the outside of the chassis, and a positioning plate is inserted into the slot.

[0006] Furthermore, the positioning plate has an "L" shaped structure, and the horizontal part of the positioning plate overlaps the chassis.

[0007] Furthermore, a handle is installed on the upper surface of the horizontal portion of the positioning plate, and the handle has a "U" shaped structure.

[0008] Furthermore, the vertical part of the positioning plate is machined with rounded corners, and the vertical part of the positioning plate is in contact with one side of the chassis.

[0009] Furthermore, a support block is installed on the lower surface of the connecting plate, and the support block slides in contact with the inner wall of the chassis.

[0010] Furthermore, the two corners at the end of the insert plate away from the connecting plate are chamfered, the insert plate and the connecting plate are integrally formed, and the insert plate and the connecting plate are arranged perpendicular to each other.

[0011] Furthermore, the upper surface of the insert plate is uniformly provided with multiple horizontal slots, and one side of the connecting plate is uniformly provided with multiple vertical slots.

[0012] Furthermore, the area of ​​the chassis covered by the cooling fan is evenly provided with multiple small holes, and the screw passes through the small holes and is threadedly connected to the cooling fan.

[0013] The beneficial effects of this utility model are: Two positioning sleeves on the connecting plate are fitted with two sets of cooling fans respectively. After the insertion plate passes through the connector, it is inserted into the positioning plate, which can quickly achieve temporary fixation of the cooling fans to the chassis. This eliminates the need for workers to hold the cooling fans in place with one hand, freeing their hands to focus on screw installation and greatly reducing the difficulty of assembly.

[0014] The positioning sleeve and cooling fan are designed to fit together, and the support block slides into the inner wall of the chassis. This ensures that the threaded hole of the cooling fan is precisely aligned with the small hole on the chassis during installation, avoiding repeated adjustments due to hole misalignment. The screws can pass smoothly through the small hole and be tightened, shortening the assembly cycle of a single server and making it suitable for mass production scenarios.

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] Please see Figures 1-4 This utility model provides a technical solution: a server cooling fan fixing device, including a chassis 1, a connector 12 on one side of the chassis 1, and two sets of exhaust nets 11 processed on the side of the chassis 1 with the connector 12; two sets of cooling fans 4 are provided, and the two sets of cooling fans 4 are respectively set inside the two sets of exhaust nets 11, and the cooling fans 4 are connected to the chassis 1 by multiple sets of screws 3; multiple small holes are evenly opened in the area of ​​the chassis 1 covered by the cooling fans 4, and the screws 3 pass through the small holes and are threadedly connected to the cooling fans 4 to complete the assembly of the cooling fans 4 and the chassis 1.

[0018] See Figures 1-4 The connecting plate 2 has two positioning sleeves 21 installed on one side, which are respectively fitted onto the two cooling fans 4. A plug plate 22 is installed at one end of the connecting plate 2, passing through the connector port 12. A slot 28 is formed on the upper surface of the plug plate 22, located on the outside of the chassis 1, and a positioning plate 23 is inserted into the slot 28. As a core connecting and positioning component, the connecting plate 2 has two integrated positioning sleeves 21 designed to precisely fit the shape of the cooling fans 4, allowing for quick and easy installation and fixing of the two sets of cooling fans 4, forming a modular assembly unit and ensuring no relative displacement between the cooling fans 4 and the connecting plate 2. The plug plate 22, integrally formed at one end of the connecting plate 2, is arranged perpendicularly to the connecting plate 2, and the end of the plug plate 2 away from the connecting plate 2 has a chamfer 29. This detail allows it to smoothly pass through the pre-set connector port 12 of the chassis 1.

[0019] After the insert plate 22 passes through the connector port 12, its slot 28 located on the outside of the chassis 1 can mate with the "L"-shaped positioning plate 23. After the positioning plate 23 is inserted into the slot 28, the horizontal part of the positioning plate 23 overlaps the surface of the chassis 1, and the vertical part of the positioning plate 23 fits against the side of the chassis 1. The connecting plate 2 and the chassis 1 are temporarily fixed through double limiting. This collaborative structure can quickly lock the installation position of the cooling fan 4 in the chassis 1, making it stably fit against the inside of the exhaust net 11. It eliminates the need for workers to hold the cooling fan 4 with one hand to maintain its balance, completely freeing up their hands. Workers can focus on the installation of the screws 3 without having to adjust the position of the cooling fan 4. This not only greatly reduces the difficulty and physical exertion of the assembly process, but also avoids the problem of imbalance caused by one-handed operation. It allows the screws 3 to pass through the small holes on the chassis 1 and mate with the threaded holes on the cooling fan 4 more smoothly, further improving the convenience and efficiency of assembly. A handle 24 is installed on the upper surface of the horizontal part of the positioning plate 23. The handle 24 has a "U" shaped structure and provides a gripping carrier for transferring the positioning plate 23. The vertical part of the positioning plate 23 is machined with rounded corners 210. The design of the rounded corners 210 makes it easy for the positioning plate 23 to be inserted into the slot 28. After the positioning plate 23 is inserted into the slot 28, the vertical part of the positioning plate 23 contacts one side of the chassis 1.

[0020] See Figures 1-4 The upper surface of the insert plate 22 has multiple horizontal slots 27 evenly distributed, and one side of the connecting plate 2 has multiple vertical slots 26 evenly distributed. The design of the horizontal and vertical slots 27 and 26 helps to reduce the material cost of the connecting plate 2 and the insert plate 22. A support block 25 is installed on the lower surface of the connecting plate 2, and the support block 25 slides in contact with the inner wall of the chassis 1. The positioning sleeve 21, as the core connecting component between the connecting plate 2 and the cooling fan 4, adopts a customized design that precisely matches the outer diameter and contour of the cooling fan 4. When fitted, it can fit tightly against the outer shell of the cooling fan 4, restricting the position of the cooling fan 4 radially and circumferentially, preventing the cooling fan 4 from shifting or rotating on the connecting plate 2. This adaptability design ensures that the threaded hole of the cooling fan 4 is always in the preset installation position, laying the foundation for subsequent alignment with the small holes on the chassis 1.

[0021] Meanwhile, the support block 25 installed on the lower surface of the connecting plate 2 forms a smooth sliding fit with the inner wall of the chassis 1. The support block 25 not only provides stable bottom support for the connecting plate 2 and the cooling fan 4, preventing the connecting plate 2 from sagging or shifting due to gravity, but also plays a guiding role in the process of the insert plate 22 passing through the connector port 12. When the support block 25 slides along the inner wall of the chassis 1, it can correct the horizontal position of the connecting plate 2 in real time, preventing the connecting plate 2 from tilting or shifting as a whole, and further calibrating the alignment accuracy between the cooling fan 4 and the chassis 1. With the synergistic effect of the two, the cooling fan 4 does not need to be manually adjusted repeatedly during installation. Its threaded hole can quickly and accurately align with the small hole on the chassis 1, completely solving the problem of screws 3 being difficult to insert due to hole misalignment and requiring multiple adjustments in traditional assembly. The screw 3 can smoothly pass through the small hole on the chassis 1 and connect with the cooling fan 4 by thread, reducing the time of ineffective operation and significantly shortening the assembly cycle of a single server cooling fan 4. For mass production scenarios, this precise alignment design significantly reduces the reliance on operator experience, allowing even novices to quickly complete assembly, effectively improving the overall assembly efficiency of the production line. At the same time, it avoids quality risks such as stripped screws and damaged threaded holes caused by hole position deviations, ensuring product consistency and stability during mass production. After the cooling fan 4 is assembled with the chassis 1, the insert plate 22 is detached from the connector port 12, and the structure formed by the connecting plate 2 and the insert plate 22 is recycled, facilitating the connection of the next chassis 1 with the cooling fan 4.

[0022] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
