Description

Technical Field

[0001] This utility model relates to the field of fan base technology, specifically a combined fan base. Background Technology

[0002] As the supporting foundation for the fan, the structural design of the fan base directly affects the stability, ease of transportation, and adaptability of the equipment.

[0003] Existing fan bases have significant limitations in their assembly design, mainly in the following aspects: Lack of assembly flexibility: Traditional fan bases are mostly one-piece molded structures, occupying a large space during transportation, increasing logistics costs, and requiring a large storage area for storage.

[0004] Insufficient structural stability: Some simple modular bases are connected only by a single clip or bolt, resulting in poor overall rigidity after assembly. Vibrations generated during fan operation can easily loosen the joints or even cause relative displacement of components, not only producing abnormal noise but also potentially shifting the fan's center of gravity and posing a risk of tipping over.

[0005] Especially in multi-component bases, if there is a lack of targeted limiting structures, each splicing unit (such as fan-shaped base plate segments) is prone to sliding radially or circumferentially, disrupting the overall support balance.

[0006] The assembly process is cumbersome: the existing interlocking bases rely heavily on tools (such as screws and wrenches) for connection, and the assembly steps are complicated, making it difficult for ordinary users to complete the installation quickly.

[0007] Therefore, a modular fan base needs to be designed. Utility Model Content

Detailed Implementation

[0029] 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.

[0030] See Figures 1-6 A modular fan base includes: a mounting base 100, which and a splicing base plate 200 together form the fan base; by disassembling the fan base into the mounting base 100 and the splicing base plate 200, a modular design is achieved, which facilitates individual production and transportation, reduces the overall processing difficulty, and allows for individual replacement of damaged parts, reducing maintenance costs.

[0031] The mounting base 100 includes an upper base 110 and a lower base 120. The mounting base 100 can be divided into an upper base 110 and a lower base 120, which can be processed and manufactured separately to adapt to different production processes. At the same time, it is convenient to optimize the structure of each part and improve the overall design flexibility.

[0032] The upper base 110 includes an annular plate 111, with a circular insertion tube 112 integrally formed at the bottom of the annular plate 111. The lower base 120 has a circular insertion hole 121 at the top center for the circular insertion tube 112 to be inserted into. A lower connecting tube 122 is integrally formed on the lower base 120, and an upper connecting tube 113 is integrally formed at the bottom of the annular plate 111 for the lower connecting tube 122 to be inserted into. The insertion and engagement of the circular insertion tube 112 with the circular insertion hole 121 and the lower connecting tube 122 with the upper connecting tube 113 achieves precise positioning and stable connection between the upper base 110 and the lower base 120. The integrally formed structure enhances the connection strength, reduces the risk of loosening, and simplifies the assembly process.

[0033] The splicing base plate 200 is composed of multiple fan-shaped plates 210 spliced ​​together. The bottom of the pointed end of the fan-shaped plate 210 is integrally formed with a round plug 211. The lower base 120 is integrally formed with a round limiting tube 123 for inserting the round plug 211. The bottom of the annular plate 111 is integrally formed with an arc-shaped locking plate 114 that engages with the round plug 211. Both sides of the arc-shaped locking plate 114 are integrally formed with limiting plates 115. The arc-shaped locking plate 114 limits the round plug 211: the arc-shaped contour of the arc-shaped locking plate 114 is adapted to the outer wall of the round plug 211. By fitting and wrapping, the circumferential limitation of the round plug 211 is achieved, preventing the round plug 211 from rotating or radially shifting in the horizontal plane, ensuring that it is stably inserted into the round limiting tube 123, and avoiding the round plug 211 from loosening or falling off due to fan vibration. The limiting plate 115 limits the sector plate 210: The limiting plate 115 is symmetrically distributed on both sides of the arc-shaped clamping plate 114. Its inner side abuts against or leaves a small gap with the side of the sector plate 210, blocking the lateral displacement of the sector plate 210 and restricting the sector plate 210 from sliding radially outward or inward in the plane of the splicing base plate 200. This prevents relative misalignment after multiple sector plates 210 are spliced, ensuring the integrity and stability of the overall structure of the splicing base plate 200. The two work together: the arc-shaped clamping plate 114 focuses on the insertion stability of the round plug 211, while the limiting plate 115 focuses on the splicing position accuracy of the sector plate 210, jointly strengthening the connection reliability between the splicing base plate 200 and the mounting base 100.

[0034] The outer end of the splicing base plate 200 is integrally formed with an arc-shaped shell 220, one end of the arc-shaped shell 220 is integrally formed with a rectangular connecting shell 230, the inside of the rectangular connecting shell 230 is integrally formed with a circular clamping tube 231, the other end of the arc-shaped shell 220 is integrally formed with a rectangular connecting groove 240, and the inside of the rectangular connecting groove 240 is integrally formed with a circular clamping post 241.

[0035] The engagement of the rectangular connecting shell 230 and the rectangular connecting groove 240, and the engagement of the circular locking post 241 and the circular locking tube 231, achieves a tight splicing of adjacent sector plates 210, enhances the overall structural strength of the splicing base plate 200, and prevents the splicing joint from loosening.

[0036] An arc-shaped connecting plate 116 is integrally formed between the outer ends of two adjacent limiting plates 115, which realizes the tight splicing of adjacent fan-shaped plates 210, enhances the overall structural strength of the splicing base plate 200, and prevents the splicing joint from loosening.

[0037] A first connecting plate 124 is integrally formed between two adjacent circular limiting tubes 123. The first connecting plate 124 connects the adjacent circular limiting tubes 123, strengthens the structural strength of the area of ​​the circular limiting tubes 123 on the lower base 120, avoids cracking caused by stress generated by the insertion of the circular plug 211, and improves the durability of the lower base 120.

[0038] The inner end of the first connecting plate 124 is integrally formed with a first annular plate 125, and the bottom of the first annular plate 125 is integrally formed with a second annular plate 126. The interior of the second annular plate 126 is integrally formed with a circular mounting tube 128 through a second connecting plate 127. The interior of the circular mounting tube 128 communicates with the circular insertion hole 121. The first connecting plate 124 connects to the adjacent circular limiting tube 123, strengthening the structural strength of the area of ​​the circular limiting tube 123 on the lower base 120, avoiding cracking caused by stress generated by the insertion of the circular plug 211, and improving the durability of the lower base 120.

[0039] There are at least four lower connecting pipes 122 arranged at equal angles. The equal-angle arrangement of the lower connecting pipes 122 ensures that the upper base 110 and the lower base 120 are subjected to uniform force, avoiding excessive local force that could lead to connection failure. The "at least four" design can adapt to different load-bearing requirements.

[0040] Holes 250 are provided on each of the sector-shaped plates 210. The holes 250 reduce the weight of the sector-shaped plates 210 and the overall weight of the splicing base plate 200, making it easier to handle and assemble, and saving material costs.

[0041] Overall assembly steps:

[0042] Assemble the splicing base plate 200: Take multiple sector plates 210, insert the rectangular connecting shell 230 of one sector plate 210 into the rectangular connecting groove 240 of the adjacent sector plate 210, so that the circular locking post 241 is inserted into the circular locking tube 231, and the multiple sector plates 210 are engaged end to end to form the splicing base plate 200.

[0043] Connecting the splicing base plate 200 to the lower base plate 120: Insert the round plug 211 of the splicing base plate 200 into the round limiting tube 123 of the lower base plate 120.

[0044] Connecting the upper base 110 and the lower base 120: Insert the round insert 112 of the upper base 110 into the round insert 121 of the lower base 120. At this time, the lower connecting tube 122 is inserted into the upper connecting tube 113. The arc-shaped clamp 114 engages with the round plug 211, completing the overall assembly of the fan base.

[0045] In summary:

[0046] This modular fan base features a modular design with multiple snap-fit ​​and plug-in structures, offering significant advantages in terms of ease of assembly, structural stability, and functional practicality.

[0047] The multiple locking and plugging structures (such as circular locking pins 241 and circular locking tubes 231, circular plug tubes 112 and circular plug holes 121) and reinforcing components (such as arc-shaped connecting plates 116 and first connecting plates 124) ensure that the connections of each component are firm, the overall structure has high strength, and can effectively resist the vibration and load during the operation of the fan.
