[0019] The following is a detailed description of the embodiments of the present invention in conjunction with the accompanying drawings and examples. The following examples are intended to illustrate the present invention but are not intended to limit the scope of the present invention. All other embodiments obtained by persons of ordinary skill in the art without creative effort are intended to fall within the scope of protection of the present invention.

[0020] Combine Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, a pull-out fan base device includes a base 1, a mounting base 2 is provided on the base 1, a power cord fixing rod 3 is provided on one side of the mounting base 2, a fan fixing foot 4 is provided on the mounting base 2, and a plurality of equidistant pulleys 11 are provided in a straight line on both sides of the base 1, and sliding grooves 5 matching the pulleys 11 are provided on both sides of the interior of the mounting base 2. The mounting base 2 can be pulled and moved on the base 1 through the cooperation of the pulleys 11 and the sliding grooves 5.

[0021] Specifically, the utility model provides a pull-out fan base device, which provides convenient installation, adjustment and maintenance operations. The device mainly includes a base 1, which serves as the supporting foundation of the entire device. The base 1 is made of sturdy and durable materials to ensure its stability and load-bearing capacity. A mounting seat 2 is provided on the base 1, and the fan assembly can be firmly installed on the mounting seat 2. A power cord fixing rod 3 is provided on one side of the mounting seat 2, which greatly facilitates the arrangement and fixation of the power cord, effectively prevents the safety hazards caused by the swinging or pulling of the power cord during the operation of the fan, and also improves the neatness and aesthetics of the entire device.

[0022] The main structure of the mounting base 2 is also equipped with fan fixing feet 4. These feet are adjustable and can be precisely adapted to fans of different models and sizes, ensuring the fan's stability and operating efficiency after installation. The fan fixing feet 4 are also designed for easy disassembly, allowing users to quickly remove and store the fan when not in use.

[0023] To enable flexible movement of the mounting base 2 on the base 1, a number of pulleys 11 are equidistantly distributed along a straight line on both sides of the base 1. These pulleys 11 not only reduce frictional resistance, making the movement of the mounting base 2 smoother, but also, through precise layout and quantity control, ensure the stability and balance of the mounting base 2 during movement. At the same time, sliding grooves 5 that perfectly match the pulleys 11 are cleverly opened on both sides of the interior of the mounting base 2. This design allows the pulleys 11 to be accurately embedded in the sliding grooves 5, forming a stable and flexible sliding connection. The user only needs to push or pull lightly, and the mounting base 2 can move freely on the base 1 along the sliding grooves 5, greatly simplifying the process of adjusting the fan position and improving work efficiency.

[0024] Through a series of ingenious designs, this pull-out fan base device not only achieves rapid installation, stable fixation and flexible adjustment of fan components, but also takes into account ease of operation and safety performance. It is an indispensable, efficient and practical equipment in modern industrial and commercial environments.

[0025] Combine Figure 2 、 Figure 3 and Figure 4As shown, a reinforcing rib 6 is provided above the sliding groove 5 , and a fixing wire hole 7 is opened on the reinforcing rib 6 . The pulley 11 can be fixed in the sliding groove 5 by the pulley fixing wire cooperating with the fixing wire hole 7 .

[0026] Furthermore, above the sliding groove 5, in order to further enhance the stability and bearing capacity of the entire structure, a reinforcing rib 6 is provided. As a structural reinforcement component, it effectively disperses and withstands various forces and pressures that may act on the mounting seat 2, thereby ensuring the stability of the sliding groove 5 and its surrounding area. Several fixing wire holes 7 are opened on the reinforcing rib 6. The fixing wire holes 7 are fixedly matched with the pulley 11. The opening of the fixing wire holes 7 provides a reliable connection point for the fixation of the pulley 11, so that the pulley 11 can be closely matched with the fixing wire hole 7 through the pulley fixing wire when needed, to achieve a stable fixing effect.

[0027] As a key component enabling the flexible movement of the mounting base 2 on the base 1, pulley 11 is also meticulously designed. Its surface is constructed of a wear-resistant, non-slip material, ensuring smooth and stable movement within the sliding groove 5. Furthermore, the axle of pulley 11 is designed with a threaded hole that matches the fixing thread hole 7, allowing the pulley's fixing thread to easily pass through the pulley and screw into the fixing thread hole 7, securing pulley 11 securely.

[0028] When the pulley 11 is tightly fitted into the fixing screw hole 7 via the pulley fixing screw, the connection between the entire mounting base 2 and the base 1 becomes more stable and reliable. This not only improves the stability of the mounting base 2 during movement, but also allows the user to easily adjust the position of the mounting base 2 as needed and fix it in a specific position when needed, thus meeting the diverse needs of different application scenarios.

[0029] Combine Figure 1 、 Figure 2 and Figure 3 As shown, the mounting base 2 is an integral U-shaped structure.

[0030] Specifically, the U-shaped structure of the mounting base 2 includes two parallel side walls and a bottom connecting the two side walls. This design enables the mounting base 2 to have excellent stability and load-bearing capacity in the horizontal direction, can effectively support the weight of the fan assembly, and prevent it from shaking or shifting during operation. At the same time, the opening design of the U-shaped structure also provides sufficient operating space for the installation and maintenance of the fan, allowing users to easily perform various operations without worrying about space constraints. Inside the U-shaped structure of the mounting base 2, sliding grooves 5 that match the pulley 11 are provided. These sliding grooves 5 ensure that the pulley 11 can move smoothly therein while maintaining sufficient stability.

[0031] Combine Figure 1 、 Figure 2 and Figure 4 As shown, the mounting base 2 is formed by splicing together a plurality of segmented bodies 8 of U-shaped structures.

[0032] Furthermore, the mounting base 2 is formed by splicing a plurality of U-shaped segmented bodies 8. This not only greatly improves the flexibility and scalability of the device, but also provides users with more personalized and customized options.

[0033] Each segmented body 8 retains the basic characteristics of a U-shaped structure, consisting of two parallel side walls and a base connecting the two side walls. These segmented bodies 8 may vary slightly in size, shape, and material, but they all undergo strict quality control and precision machining to ensure that they fit together perfectly to form a structurally stable and fully functional mounting base 2.

[0034] During installation, users can select the appropriate number and arrangement of segmented bodies 8 to meet the installation requirements of different fan assemblies. This modular design allows the mount 2 to easily adapt to various complex installation environments, whether large industrial plants or small commercial spaces, to find the most suitable solution.

[0035] To ensure secure and stable splicing, high-strength connectors and fasteners, such as bolts and nuts, are used at the joints of the segmented bodies 8. These connectors are not only able to withstand the weight of the wind turbine components and the various forces during operation, but also prevent the segmented bodies 8 from loosening or deforming over time. When the user needs to adjust the position of the wind turbine components or perform maintenance, they can easily remove the segmented bodies 8 by simply loosening the connectors. This design not only improves work efficiency but also reduces maintenance costs.

[0036] Combine Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, connecting plates 23 are provided on the outer sides of both ends of the segmented body 8, and bolt holes 24 are provided on all connecting plates 23. Between two adjacent segmented bodies 8, a positioning hole 25 is provided on the connecting plate 23 at one end of one segmented body 8, and a positioning pin 26 matching the positioning hole 25 is provided on the connecting plate 23 at the other end of the other adjacent segmented body 8.

[0037] Specifically, connecting plates 23 are provided on the outer sides of each segmented body 8. These connecting plates 23 not only connect adjacent segmented bodies 8 but also, through their bolt holes 24, provide reliable fastening points for assembling the entire mounting base 2. The bolt holes 24 ensure that the position, size, and spacing of each hole perfectly match standard bolts and nuts. This allows users to easily and securely connect adjacent segmented bodies 8 together using bolts and nuts when assembling the mounting base 2, forming a mounting base with a stable overall structure and strong load-bearing capacity.

[0038] To further improve the connection accuracy and stability between the segmented bodies 8, a matching design of positioning holes 25 and positioning pins 26 is added to the connecting plates 23. One or more positioning holes 25 are provided on the connecting plate 23 at one end of a segmented body 8, and the shape and size of these holes match the positioning pins 26. A corresponding positioning pin 26 is provided on the connecting plate 23 at the other end of the adjacent segmented body 8.

[0039] During assembly, the user simply needs to accurately insert the positioning pins 26 into the positioning holes 25 on adjacent segmented bodies 8 to achieve preliminary positioning of the two segmented bodies 8. This not only greatly simplifies the assembly process and reduces the accuracy requirements, but also ensures that each segmented body 8 is accurately placed in the predetermined position, thereby improving the assembly accuracy and stability of the entire mounting base 2.

[0040] Combine Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, a baffle 21 is provided inside one end of the mounting base 2 , a fixing pin 22 is provided on the baffle 21 , and the other end of the mounting base 2 is connected to the push-pull frame 9 .

[0041] Furthermore, a baffle 21 is provided inside one end of the mounting base 2, which not only enhances the structural strength of the mounting base 2 but also provides an additional support point for fixing the fan.

[0042] Baffle 21 is made of high-quality materials with excellent wear and corrosion resistance, ensuring stable performance over long-term use. Its shape and size are carefully calculated to ensure a close fit within the internal structure of mounting base 2 without interfering with the normal installation and operation of the fan.

[0043] Fixing pins 22 are installed on the baffle 21. These pins 22 are made of high-strength material, offering excellent load-bearing capacity and shear resistance. They secure the fan and prevent it from shaking or shifting during operation. The pins 22 are also designed for easy removal, allowing the user to easily remove the fan from the mounting base 2 for maintenance or replacement when necessary.

[0044] A push-pull bracket 9 is attached to the other end of the mounting base 2. As a key component enabling the flexible movement of the mounting base 2 on the base 1, the push-pull bracket 9 is constructed from durable materials, capable of bearing the combined weight of the mounting base 2 and the fan assembly, while maintaining stable performance during movement. The shape and size of the push-pull bracket 9 perfectly match the end of the mounting base 2, ensuring a secure connection between the two. Furthermore, the push-pull bracket 9 features a convenient handle or grip for easy gripping, allowing users to easily push or pull the mounting base 2 for quick movement and adjustment of the fan.

[0045] Combine Figure 1 and Figure 2 As shown, the base 1 is a rectangular groove-shaped structure, and a fixing hole 12 matching the fixing pin 22 is opened on the top groove wall of the base 1.

[0046] Combine Figure 1 and Figure 2 As shown, a plurality of equidistant support legs 13 are arranged in a straight line on both sides of the bottom of the base 1 , and all the support legs 13 are provided with mounting holes.

[0047] Specifically, base 1, as the fundamental support component of the entire pull-out fan base assembly, fully integrates considerations of stability, practicality, and convenience. Base 1 presents a rectangular trough-like structure, which not only provides ample space for mounting base 2 and the fan assembly thereon, but also ensures the horizontal stability of the entire assembly.

[0048] Specially designed fixing holes 12 are provided on the top groove wall of the base 1 to match the fixing pins 22. The position, size, and shape of these fixing holes 12 are precisely calculated to ensure a tight fit with the fixing pins 22 on the mounting base 2. When the mounting base 2 is inserted into the groove of the base 1, the fixing pins 22 automatically align and insert into the corresponding fixing holes 12, thus achieving a secure connection between the mounting base 2 and the base 1. This not only simplifies the installation process and reduces the precision requirements, but also ensures the stability of the entire device during operation.

[0049] Several equally spaced support legs 13 are arranged along a straight line on both sides of the bottom of the base 1. These legs 13 not only provide stable support for the entire device but also ensure stable placement on any surface. They evenly distribute the weight of the device, preventing deformation or damage caused by excessive local pressure.

[0050] Mounting holes are provided on the support legs 13. These holes provide users with a variety of installation options. Users can select the appropriate mounting hole locations based on their needs and secure the base 1 to the ground using fasteners such as bolts and nuts. This not only improves the stability of the entire device but also allows users to flexibly adjust it to suit different installation environments and needs.

[0051] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
