[0024] Embodiment 2:

[0025] like Figure 1-Figure 7As shown, the main purpose of the utility model is to solve the problem that the existing cooling fan is easy to lose balance when rotating at high speed. When the fan rotates at high speed, the fan blades 4 cause vibrations due to uneven mass distribution and external force. If there is no effective stabilization mechanism, these vibrations will cause the fan blades to touch the base, causing the fan to make abnormal noises, damaging the fan blades 4 and the base 1, thereby shortening the service life of the cooling fan. The base 1 of the utility model is provided with a motor base 2 at the bottom. The base 1 is the basic part of the entire cooling fan, and its function is to provide a stable support platform. The motor base 2 is installed with a motor stator 3. The motor stator 3 is the fixed part of the motor, and a magnetic field is generated by electromagnetic induction, thereby driving the motor rotor to rotate. The motor stator 3 drives the connection blade 4. A fixing hole 5 is provided at the center of the fan blade 4. The fixing hole 5 is installed with a main shaft 6. Both ends of the main shaft 6 are provided with a card slot 7. The card slot 7 is fixedly connected with a retaining spring 8. The motor stator 3 is connected to the fan blade 4 through the main shaft 6. The main shaft 6 is installed in the fixing hole 5 of the fan blade 4. The card slot 7 is provided at both ends of the main shaft 6. The card slot 7 is fixedly connected by a retaining spring 8. The motor stator 3 is connected to the fan blade 4 through the main shaft 6. The main shaft 6 is installed in the fixing hole 5 of the fan blade 4. The card slot 7 is fixedly connected by the retaining spring 8. This design ensures that the fan blade 4 can remain stable when rotating at high speed. The stabilizing frame 9 is the core part of this technology. The stabilizing frame 9 includes a support leg 10, a latch block 11 and a disc seat 12. The disc seat 12 is the main part of the stabilizing frame 9, and a bearing fixing hole 13 is provided in the center thereof, and the main shaft 6 is movably connected through a bearing 14. The function of the bearing 14 is to reduce the friction between the main shaft 6 and the disc seat 12, thereby ensuring that the main shaft 6 can rotate smoothly. The disc seat 12 is extended with four support legs 10, and the function of the support legs 10 is to provide additional support to ensure the stability of the entire cooling fan. The support leg 10 is extended with a latch block 11, which is used to fix the connection between the stabilizing frame 9 and the base 1, ensuring that the stabilizing frame 9 will not shift or fall off when the fan rotates at high speed. Through this design, the cooling fan can remain stable when rotating at high speed, avoiding abnormal noise and damage caused by vibration, thereby extending the service life of the cooling fan. In addition, this design also has the advantages of easy installation and convenient maintenance. During maintenance, the fan blades 4 and the stabilizing frame 9 can be easily disassembled for cleaning and maintenance by simply loosening the retaining spring 8 and the latch block 11. The utility model introduces the stabilizing frame 9 structure into the heat dissipation fan, effectively solving the problem that the existing heat dissipation fan is easy to lose balance when rotating at high speed, avoiding the abnormal sound and damage caused by vibration, thereby extending the service life of the heat dissipation fan. In addition, this design also has the advantages of easy installation and convenient maintenance, and has high practical value and promotion prospects.

[0026] The base 1 of the utility model is provided with a plug hole 15, and the plug block 11 is plugged and fixed with the plug hole 15. The main purpose of this design is to further enhance the stability of the cooling fan, simplify the installation and disassembly process, and provide a more reliable fixing method. The base 1 is the supporting structure of the entire cooling fan, and its main function is to provide a stable platform to install and fix other components. The base 1 is provided with plug holes 15, and the positions and numbers of these plug holes 15 correspond one by one to the plug blocks 11 on the stabilizing frame 9 to ensure that they can be perfectly docked with the plug blocks 11. The plug block 11 is an important part of the stabilizing frame 9, and its main function is to firmly fix the stabilizing frame 9 on the base 1 by plugging and fixing with the plug hole 15. The plug block 11 is usually made of high-strength material to ensure that it will not deform or break under high stress conditions. The plug block 11 can be firmly inserted into the plug hole 15 to prevent loosening or falling off due to vibration or other external forces. This plug-in fixed design not only enhances the overall stability of the cooling fan, but also greatly simplifies the installation and disassembly process. During the installation process, the user only needs to align the plug block 11 with the plug hole 15, and then gently press the plug block 11 to firmly insert it into the plug hole 15 to complete the installation. This design avoids the use of screws or other fasteners, reduces the installation steps, and improves the installation efficiency. At the same time, when maintenance or replacement of components is required, the user only needs to gently pull out the plug block 11 to easily disassemble the stabilizing frame 9 and other components, which greatly simplifies the maintenance process. The utility model further enhances the stability and reliability of the cooling fan by providing the plug hole 15 on the base 1 and fixing the plug block 11 to the plug hole 15. This design not only simplifies the installation and disassembly process, but also improves the installation and maintenance efficiency.

[0027] The latch block 11 of the utility model is provided with a blind hole 16. The design of the blind hole 16 plays a vital role in the stability and installation convenience of the cooling fan. The blind hole 16 refers to a hole that is open at only one end and closed at the other end. This design has multiple application advantages in mechanical structures. The design of the blind hole 16 can effectively improve the elastic performance of the latch block 11. When the latch block 11 is inserted into the plug hole 15 of the base 1, the latch block 11 can undergo a certain degree of elastic deformation when the blind hole 16 exists, so that the latch block 11 can be firmly connected to the plug hole 15. The design of the blind hole 16 can also reduce the manufacturing consumables of the latch block 11 and reduce the production cost.

[0028] The side of the latch block 11 of the utility model is provided with a tensioning rib 17. The design of the tensioning rib 17 plays a key role in the fixation and stability of the cooling fan, and further improves the performance and reliability of the cooling fan. The tensioning rib 17 refers to a protrusion or reinforcement rib provided on the side of the latch block 11, and its main function is to increase the clamping firmness between the latch block 11 and the plug hole 15. When the latch block 11 is inserted into the plug hole 15, the tensioning rib 17 can be in close contact with the inner wall of the plug hole 15 to form a more secure connection. This design can effectively prevent the latch block 11 from loosening or falling off due to vibration or external force when the fan rotates at high speed, ensuring that the cooling fan remains stable during operation. The design of the tensioning rib 17 can significantly improve the fixing strength of the latch block 11. Since the tensioning rib 17 increases the clamping force between the latch block 11 and the plug hole 15, the latch block 11 can be more firmly fixed on the base 1 after being inserted into the plug hole 15. This design can effectively prevent the latch block 11 from loosening or falling off due to vibration or external force, ensure that the cooling fan remains stable when rotating at high speed, and avoid abnormal noise and damage caused by vibration. The design of the tension rib 17 can also simplify the installation process of the latch block 11. Since the tension rib 17 can be in close contact with the inner wall of the plug hole 15, the user only needs to gently press the latch block 11 when installing the latch block 11, so that it can be firmly inserted into the plug hole 15 to complete the installation. This design avoids the use of additional fasteners, reduces installation steps and time, and improves installation efficiency. At the same time, when maintenance or replacement of components is required, the user only needs to gently pull out the latch block 11 to easily disassemble the stabilizing frame 9 and other components, which greatly simplifies the maintenance process.

[0029] The motor base 2 of the utility model is provided with a wire groove 18, and the wire groove 18 is fixedly connected with a buckle 19. The motor base 2 is an important component of the cooling fan. The motor base 2 is provided with a wire groove 18, and the main function of these wire grooves 18 is to accommodate and guide the wires to ensure that the wires will not be damaged or disturbed during the operation of the fan. The existence of the wire groove 18 can effectively solve the problem of wire management. In the actual application of the cooling fan, the wiring and fixing of the wires are often a complex and error-prone link. If the wires are improperly wired, the wires will be worn, broken, and even cause safety problems such as short circuits. By arranging the wire groove 18 on the motor base 2, the wires can be neatly stored and guided, avoiding the mess and crossing of the wires, and reducing the risk of the wires being damaged by external forces. Secondly, the buckle 19 is fixedly connected in the wire groove 18, and this design further enhances the fixing effect of the wires. The buckle 19 is a simple and effective fixing device, and its main function is to firmly fix the wires in the wire groove 18 to prevent the wires from falling off or moving due to vibration or external force during the operation of the fan. The buckle 19 is usually made of high-strength material and has good durability and reliability. The use of the buckle 19 not only improves the fixing strength of the wire, but also simplifies the installation and maintenance process of the wire. When installing the wire, the user only needs to put the wire into the wire groove 18, and then snap the buckle 19 onto the wire groove 18 to complete the fixing of the wire. This design avoids the use of additional binding tapes or tapes, reduces installation steps and time, and improves installation efficiency.

[0030] The stabilizing frame 9 of the utility model is made of PVC plastic material. The stabilizing frame 9 made of PVC (polyvinyl chloride) plastic material has significant advantages in terms of structural stability, durability, manufacturing cost and environmental adaptability of the cooling fan. PVC plastic material has excellent mechanical properties. The strength and rigidity of PVC material are high, which can effectively support the various components of the cooling fan and ensure that the fan remains stable when rotating at high speed. As the supporting structure of the cooling fan, the stabilizing frame 9 needs to bear the weight of the fan blades 4 and the motor, and also resist the vibration and impact force generated when the fan is running. The high strength and impact resistance of PVC material enable it to maintain stability under these harsh conditions and prevent the fan from shaking or deforming during operation. PVC plastic material has good corrosion resistance. In actual applications, cooling fans are often exposed to various environments, including high temperature, high humidity and corrosive gases. Metal materials are prone to corrosion in these environments, resulting in performance degradation or even failure. PVC material has excellent chemical corrosion resistance, which can effectively resist the erosion of chemical substances such as acids, alkalis and salts, and extend the service life of the stabilizing frame 9. In addition, the PVC material also has good weather resistance, can maintain stable performance under long-term sunlight and rain erosion, and will not age or become brittle. PVC plastic material has a low manufacturing cost. Compared with metal materials, the cost of PVC materials is low, and the processing technology is simple, and it can be mass-produced through processes such as injection molding and extrusion. The PVC material has strong plasticity and can be processed into various shapes and sizes according to design requirements to meet the needs of different cooling fans. The low-cost and high-efficiency manufacturing process makes the PVC material stabilizer 9 highly competitive in the market, which can effectively reduce the production cost of the cooling fan and improve the cost performance of the product. PVC plastic material has good electrical insulation performance. In the design of the cooling fan, electrical safety is an important consideration. As the supporting structure of the fan, the stabilizer 9 is usually in contact with electrical components such as motors and cables. If conductive materials are used, safety issues such as electrical short circuits or electric shocks will be caused. The PVC material has excellent electrical insulation performance, which can effectively prevent current leakage and ensure the electrical safety of the cooling fan. PVC plastic material also has the characteristics of light weight. Compared with metal materials, the density of PVC materials is lower, and the use of the stabilizing frame 9 made of PVC material can effectively reduce the overall weight of the cooling fan.
