Description

Technical Field

[0001] This utility model relates to the field of ceiling fan technology, and specifically to a fan bell with quick-release components. Background Technology

[0002] In modern industrial and civil equipment, the design and application of hoisting devices are crucial for improving installation efficiency, ease of use, and maintenance. This is especially true during the installation of equipment such as fans, where the structural design of the hoisting components directly impacts the equipment's stability and ease of operation. Traditional fan hoists typically employ a fixed installation structure, with the connection between the hanger and the housing relying heavily on bolts or welding. While this design meets basic load-bearing requirements, it has several shortcomings in practical use. For example, the fixed installation method leads to complex and time-consuming disassembly and maintenance processes, particularly in scenarios requiring frequent fan position changes or adjustments, where traditional designs struggle to meet the demands for rapid assembly and disassembly. Furthermore, traditional hoisting components lack effective swing guidance and limiting functions during fan operation, making them prone to loosening or deviating from their intended position due to fan vibration or external interference, thus affecting the equipment's stability and safety.

[0003] In existing technologies, some lifting devices attempt to address the aforementioned problems by adding quick-release components. However, these designs often suffer from structural complexity, inconvenient operation, and insufficient reliability. For example, while some quick-release components can achieve rapid connection between the lifting frame and the housing, their poorly designed limiting structures can easily lead to loosening during use, increasing safety hazards. Furthermore, the design of existing lifting components for fan oscillation guidance is relatively simplistic, typically relying on simple spherical or cylindrical structures for limiting, lacking precise control over the oscillation angle and direction, making it difficult to meet the requirements of high-precision installation and stable operation. In addition, traditional lifting components have limited load-bearing capacity and are prone to deformation or damage under heavy loads, further limiting their application scenarios.

[0004] Therefore, there is an urgent need for a novel fan bell design with quick-release components, capable of rapid assembly and disassembly between the hanger and the housing while ensuring structural strength and stability, and possessing precise swing guidance function to meet the needs of efficient installation and stable operation of fan equipment in different scenarios. Based on this background, this invention proposes an innovative solution aimed at overcoming the shortcomings of existing technologies and providing a more reliable, convenient, and efficient structural form for the design of fan bells. Utility Model Content

[0005] In view of the above situation and to overcome the defects of the prior art, the purpose of this utility model is to provide a fan bell with quick-release components, which effectively solves the problem that existing fan bells are inconvenient to disassemble and replace.

[0006] The technical solution provided by this utility model is a fan bell with a quick-release assembly, wherein the housing, the hanging frame, and the fan hoisting assembly are arranged sequentially from low to high along the height direction. The hanging frame is disassembled and installed in the housing via the quick-release assembly and is provided with a support frame for supporting the fan hoisting assembly.

Detailed Implementation

[0015] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0016] Refer to the instruction manual appendix Figure 1-9 This invention provides a fan-shaped pendant clock with quick-release components. Its structural design aims to solve the problems of cumbersome installation and disassembly, insufficient stability, and limited swing flexibility in existing technologies. The specific embodiments of this invention will be described in detail below with reference to the accompanying drawings.

[0017] Example 1, such as Figure 1 As shown, the overall structure of this utility model consists of a housing 1, a hanger, and a fan mounting assembly. The housing 1 is the outer shell of the overall structure, with the hanger and fan mounting assembly arranged sequentially from low to high along the height direction. The hanger is connected to the housing 1 via a quick-release mounting assembly, enabling rapid disassembly and installation. The hanger has a support frame for supporting one end of the fan mounting assembly. The other end of the fan mounting assembly penetrates the housing 1 and extends beyond it, for mounting the fan.

[0018] The support frame is the core component of the fan mounting assembly, and its structure is as follows: Figure 2 As shown, the support frame includes a main body 2, a swing guide block 3, and a hemispherical swing groove 4. The hemispherical swing groove 4 is formed on the main body 2 to accommodate one end of the fan mounting assembly. The swing guide block 3 is disposed within the hemispherical swing groove 4 to guide the swing of the fan mounting assembly. The design of the swing guide block 3 allows the fan mounting assembly to swing flexibly within a certain range while limiting its swing trajectory to ensure stability. The shape of the swing guide block 3 fits against the inner edge of the hemispherical swing groove 4, thereby preventing the fan mounting assembly from detaching from the hemispherical swing groove 4.

[0019] The structure of the fan mounting assembly is as follows: Figure 3As shown, it mainly includes a hanging ball 5 and a hanging tube 6. The hanging ball 5 is installed inside the hemispherical swing groove 4, and fits tightly against the inner edge of the hemispherical swing groove 4. A guide groove 7 is provided on the hanging ball 5 to accommodate the swing guide block 3. The design of the guide groove 7 allows the hanging ball 5 to be constrained by the swing guide block 3 during swinging, preventing it from deviating from the predetermined swing trajectory. The hanging tube 6 is fixedly connected to the hanging ball 5 by bolts, and one end of it passes through the hanging ball 5 and extends out of the housing 1 for mounting the fan. The length of the hanging tube 6 can be adjusted according to actual needs to accommodate fans of different sizes.

[0020] The design of the quick-release hoisting assembly is divided into two schemes, as follows: Figure 4 and Figure 6 As shown. In the first design scheme, the quick-release assembly includes a fixed part 8 and a first rotating part. The fixed part 8 is fixedly connected to the hanger by bolts, and is used to connect the hanger to the housing 1. The fixed part 8 has multiple first limiting grooves, which are evenly distributed on the outer edge surface of the fixed part 8. Each first limiting groove includes a first slot 9 and a blocking block 10. The first slot 9 is inverted L-shaped and is used to accommodate the first rotating part. The blocking block 10 is located in the first slot 9 and is used to limit the first rotating part to prevent it from disengaging from the first slot 9 without human intervention. The first rotating part includes a support ring 15 and a limiting block 16. The support ring 15 is fixedly connected to the housing 1 and is used to support the limiting block 16. The limiting block 16 is located inside the support ring 15 and is inserted into the first slot 9, and is slidably connected to the first slot 9. The sliding process of the limiting block 16 in the first slot 9 realizes the quick disassembly and installation function of the hanger. An auxiliary surface 17 is also provided inside the first slot 9. The auxiliary surface 17 is inclined upward along the rotation direction and has auxiliary blocks 18 distributed in a wave-like pattern. The auxiliary blocks 18 increase the friction between the limiting block 16 and the first slot 9, thereby improving the stability of the connection.

[0021] In Embodiment 2, the second design scheme includes a quick-release hoisting assembly comprising a fixed part 8 and a second rotating part. The fixed part 8 is also fixedly connected to the hanger by bolts. Multiple second limiting grooves are evenly distributed on the fixed part 8. Each second limiting groove penetrates the fixed part 8 and is arc-shaped, coaxial with the fixed part 8. The second limiting groove includes a second slot 12, a through hole 13, and a limiting platform 14. The limiting platform 14 is located within the second slot 12 and is used to limit the second rotating part. The through hole 13 is located on one side of the limiting platform 14 and is used for insertion of the second rotating part. The second rotating part includes a support base 19, a limiting post 20, and a limiting disc 21. The support base 19 is fixedly connected to the housing 1 by bolts and is used to support the limiting post 20. The limiting post 20 is located on the support base 19 and is conical, inserted into the through hole 13, and slides along the inner edge of the limiting platform 14, thereby achieving quick disassembly and installation of the hanger. The limiting plate 21 is located on the top of the limiting post 20 and has the same diameter as the through hole 13. It is used to limit the position of the limiting plate 14 to prevent the limiting post 20 from disengaging from the through hole 13 without human intervention.

[0022] The structure of the hanger is as follows Figure 8 As shown, the system includes a positioning plate 22 and a fixing plate 23. The positioning plate 22 is located between the support frame and the fixing part 8 and is fixedly connected by bolts to enhance the overall stability of the hanger. The fixing plate 23 is connected to the positioning plate 22 via a connecting plate 24. The fixing plate 23 has auxiliary holes 25 for fixing the hanger, thereby further improving the connection strength between the hanger and the housing 1. The overall design of the hanger enables it to have high rigidity while bearing the weight of the fan, meeting the stability requirements during fan operation.

[0023] In practical applications, this fan-mounted clock can be used in various scenarios such as homes and commercial spaces. During installation, the hanging bracket is first fixed inside the housing 1 using the quick-release assembly. Then, one end of the fan mounting assembly is installed inside the support frame, while the other end passes through the housing 1 and extends outwards for fan mounting. The hanging ball 5 of the fan mounting assembly swings within the hemispherical swing groove 4, guided by the swing guide block 3, thus enabling the fan to swing flexibly within a certain range. When disassembly is required, the hanging bracket can be quickly removed from the housing 1 by operating the quick-release assembly; the entire process is simple and fast.

[0024] The design of auxiliary surface 17 and auxiliary block 18 in the quick-release hoisting assembly significantly improves the connection stability between the hanger and the housing 1, making the fan bell more reliable during operation.

[0025] In summary, this utility model, through optimized structural design, achieves rapid disassembly and installation of the fan bell, while ensuring the stability and oscillation flexibility of the fan during use. Both design schemes for the quick-release hoisting component possess high practical value and can meet the usage needs in different scenarios.
