Description

Technical Field

[0001] This utility model relates to the field of splicable structure technology, and in particular to an infinitely long splicable conductive structure, as well as a column assembly and fan having an infinitely long splicable conductive structure. Background Technology

[0002] In structural applications requiring adjustable height or length, such as fans, lighting brackets, and display racks, traditional solutions typically employ telescopic pole structures to achieve height adjustment. However, these telescopic structures rely primarily on nested sleeves with locking or clamping mechanisms, such as spring buttons or rotating locking rings, to fix different height positions. Their height adjustment range is limited by preset fixing spacing or the number of nested sections. When users require heights exceeding the preset range, existing telescopic structures often cannot meet the needs, limiting the applicability of the equipment. Furthermore, traditional telescopic pole structures generally suffer from difficulties in internal wiring design. On one hand, the sleeves of the telescopic pole typically use a tight nesting fit to ensure structural stability, resulting in extremely small gaps that make it difficult to run wires within the limited space. On the other hand, to prevent dust and moisture from entering or to maintain a clean appearance, some telescopic structures employ a sealed design, further hindering the possibility of internal wiring. This forces wires to be exposed on the outside of the pole, affecting the overall aesthetics of the equipment and making them susceptible to insulation damage due to external friction, bending, or environmental corrosion, leading to short circuits, leakage, and other safety hazards, especially in humid or high-dust environments. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes an infinitely long splicing conductive structure, which achieves infinite length expansion through hollow connecting columns and threaded splicing. Combined with the elastic conduction between the conductive columns and conductive rings, it solves the problems of limited length and inability to internally route wiring in traditional telescopic structures. It also features flexible adjustment, safe wiring, simple assembly, and wide applicability, improving the functional integration and reliability of the equipment.

[0004] This utility model also proposes a column assembly and a fan having the above-mentioned infinitely long spliced ​​conductive structure.

[0005] The infinitely long spliced ​​conductive structure according to this utility model includes: At least two connecting posts are provided, and adjacent connecting posts are fixedly connected by threads; At the connection point of the two connecting posts, one of the connecting posts is provided with at least two separately arranged conductive posts, and the other connecting post is provided with at least two separately arranged conductive rings, with the conductive rings corresponding to the conductive posts one by one. The conductive post is floating on the axis of the connecting post so that when the two connecting posts are screwed together, the conductive post and the conductive ring press against each other and conduct electricity. The connecting post has a hollow structure to allow wires connected to the conductive post and the conductive ring to pass through.

[0006] According to the infinitely long splicing conductive structure described in this utility model, it has at least the following beneficial effects: When mechanically fixed by tightening the threads of adjacent connecting posts, the conductive post floating on one connecting post automatically presses against and contacts the conductive ring on the other connecting post to form a stable electrical conduction. Splicing and conductive path construction can be completed simultaneously without additional operation, simplifying the assembly process and improving connection efficiency. The design of at least two separately arranged conductive posts and conductive rings not only ensures the physical isolation and reasonable layout of multi-line conduction but also ensures the independence and accuracy of each conductor's conduction path through a one-to-one correspondence, effectively avoiding multi-line cross-interference and improving the stability and reliability of the conductive system. Furthermore, the hollow structure of the connecting post provides a physical channel for internal wiring, allowing wires to be directly integrated inside the connecting post and connected to the conductive post and conductive ring. This avoids the safety hazards and environmental adaptability risks caused by exposed wires and provides integrated wiring space for various types of cables such as power lines and control signal lines, meeting the integration needs of complex equipment for internal functional cables. In addition, the design also... The threaded connection method allows users to freely increase or decrease the number of connecting posts to flexibly adjust the overall structural length according to actual needs, breaking through the limitations of the fixed adjustment range of traditional telescopic poles. It adapts to the personalized requirements of different scenarios for height or length. At the same time, each splice forms a continuous conductive path through conductive posts and conductive rings, ensuring that the internal wires remain conductive after any length extension, achieving true "infinite length" splicing and integrated conductivity. In addition, the floating setting of the conductive posts allows them to adaptively adjust the contact pressure when pressed against the conductive rings. Even if there are slight axial deviations or assembly errors during the splicing process, they can still maintain a stable and tight contact through elastic force, reducing contact resistance and improving conductivity reliability. The whole structure not only facilitates disassembly, inspection, or replacement of internal wires, but also supports integration with other standard components such as bases and fan heads, enhancing the application flexibility and scalability of the structure. It can be widely used in various equipment scenarios that require height adjustment and internal wiring, such as fan columns, lighting brackets, and display racks, and has outstanding practical value and technological promotion significance.

There are also three conductive rings with gradually increasing diameters, arranged sequentially around the conductive pillars to correspond one-to-one with each of the conductive pillars.

[0015] The column assembly described in this utility model has at least the following beneficial effects: Utilizing the flexibility of threaded splicing, the number of connecting columns can be freely increased or decreased according to requirements, breaking through traditional fixed height limitations and meeting the usage requirements of diverse scenarios.

The hollow connecting column and conductive design allow power cords, motor control wires, etc., to pass through from the base to the fan head, avoiding wear, tangling, or electric shock risks caused by exposed wires. This is especially suitable for scenarios with high safety requirements, such as families with children or pets. This design integrates height adjustment, internal wiring, and conductivity into the core structure of the fan, significantly improving the product's functionality, safety, and market competitiveness, providing users with a more convenient and reliable user experience.

[0026] like Figures 1 to 2As shown, the infinitely long splicing conductive structure proposed in this utility model includes at least two connecting posts 100, wherein adjacent connecting posts 100 are threadedly connected and fixed. Specifically, at the connection point of the two connecting posts 100, one connecting post 100 is provided with at least two separately arranged conductive posts 210, and the other connecting post 100 is provided with at least two separately arranged conductive rings 220, with the conductive rings 220 corresponding to the conductive posts 210 one-to-one. Further, the conductive posts 210 are floating on the axis of the connecting posts 100, so that when the two connecting posts 100 are screwed together, the conductive posts 210 and the conductive rings 220 press against each other and conduct electricity. The connecting posts 100 are hollow structures to allow wires connected to the conductive posts 210 and the conductive rings 220 to pass through. When mechanically fixed by tightening the threads of adjacent connecting posts 100, the conductive post 210 floating on one connecting post 100 automatically presses against the conductive ring 220 on the other connecting post 100 to form a stable electrical connection. This allows for simultaneous splicing and conductive path construction without additional operation, simplifying the assembly process and improving connection efficiency. The design using at least two separately arranged conductive posts 210 and conductive rings 220 not only ensures physical isolation and layout rationality for multi-line conduction but also guarantees the conductive path of each wire through a one-to-one correspondence. The independence and accuracy of the wire diameter effectively avoids interference from multiple wire crossings, improving the stability and reliability of the conductive system. Furthermore, the hollow structure of the connecting post 100 provides a physical channel for internal wiring, allowing wires to be directly integrated inside the connecting post 100 and connected to the conductive post 210 and conductive ring 220. This avoids safety hazards and environmental adaptability risks associated with exposed wires, and provides integrated wiring space for various types of cables such as power lines and control signal lines, meeting the integration needs of complex equipment for internal functional cables. Additionally, the threaded connection method... This design allows users to freely increase or decrease the number of connecting columns 100 to flexibly adjust the overall structural length according to actual needs, breaking through the limitations of the fixed adjustment range of traditional telescopic poles. It adapts to the personalized requirements of different scenarios for height or length. At the same time, each splicing point forms a continuous conductive path through the conductive column 210 and the conductive ring 220, ensuring that the internal wires remain conductive after any length extension, achieving a true "infinite length" splicing and conductive function integration. In addition, the floating setting of the conductive column 210 allows it to adaptively adjust the contact pressure when it is pressed against the conductive ring 220. Even if there is a slight axial deviation or assembly error during the splicing process, it can still maintain a stable and tight contact through elastic force, reducing contact resistance and improving conductive reliability. The whole structure is not only easy to disassemble, inspect or replace the internal wires later, but also supports the adaptation and integration with other standard components such as the base 500 and the fan head 600, enhancing the application flexibility and scalability of the structure. It can be widely used in various equipment scenarios that require height adjustment and internal wiring, such as fan columns, lighting brackets, and display racks, and has outstanding practical value and technical promotion significance.

[0027] In some embodiments of this utility model, reference is made to Figure 1 At the junction of the two connecting posts 100, one of the connecting posts 100 has a connecting part 110 at its top, and the outer wall of the connecting part 110 has an external thread 111. The bottom inner wall of the other connecting post 100 has an internal thread 101 that connects with the external thread 111. The outer diameter of the connecting part 110 is smaller than the outer diameter of the connecting post 100, so that it can be hidden inside the junction of the two connecting posts 100 after threaded connection. By setting the top of one of the connecting posts 100 as a connecting part 110 with an outer diameter smaller than the outer diameter of the main body, and providing an external thread 111 on its outer wall, the tightened connecting part 110 is hidden in the splicing space of the two connecting posts 100, making the overall appearance after splicing smoother, reducing the risk of interference from the protruding structure to the external environment, enhancing the structural compactness of the splicing joint, reducing the possibility of dust or foreign objects entering the thread gaps, and improving the durability and protection of the connecting part 110. In addition, the concealed threaded connection further reduces the overall thickness of the splice and optimizes space utilization, making it particularly suitable for scenarios with high dimensional accuracy requirements. While ensuring mechanical connection strength and electrical conductivity reliability, it also enhances the product's aesthetics and practicality.

[0028] Refer to Figure 1 and Figure 2In some embodiments of this invention, a mounting base 300 is installed at the end of one of the connecting posts 100. A compression spring 310 is provided between the conductive post 210 and the mounting base 300. The elastic force of the spring drives the conductive post 210 to extend outward from the mounting base 300, ensuring that the conductive post 210 maintains a stable pressing state when in contact with the conductive ring 220 of the other connecting post 100. Furthermore, even if there is a slight axial offset or assembly error during the splicing process, the elastic force can adaptively adjust the contact pressure, which can match the different tightening depths when adjacent connecting posts 100 are fully tightened or almost tightened, maintaining a tight contact between the conductive post 210 and the conductive ring 220, significantly reducing contact resistance and improving the stability of the conductive path. In addition, the floating structure driven by the compression spring 310 simplifies the assembly process of the conductive post 210, achieving reliable conduction without high-precision positioning, reducing manufacturing costs and maintenance difficulty, and is especially suitable for scenarios requiring frequent disassembly or long-term use. Optionally, the mounting base 300 can be disassembled into a first half-base 301 and a second half-base 302 that can be assembled in opposite directions. The conductive post 210 is installed in the first half-base 301 and then secured by the two halves. This modular design significantly improves the ease of assembly between the conductive post 210 and the mounting base 300. In some assembly applications, operators can first fix the conductive post 210 to the first half-base 301, and then quickly complete the assembly of the mounting base 300 by assembling the second half-base 302. This eliminates the need for complex tools or precise alignment, simplifying the production process and improving assembly efficiency. Furthermore, the split structure facilitates individual maintenance or replacement of components such as the conductive post 210 or springs without requiring the complete disassembly of the connecting post 100, reducing equipment maintenance costs and downtime. Optionally, a reasonable snap-fit ​​design ensures a secure assembly of the first half-base 301 and the second half-base 302. Furthermore, the mounting base 300 is snap-fitted onto the inner wall of the connecting post 100, simplifying the fixing process between the mounting base 300 and the main body of the connecting post 100. No additional threading or welding is required, reducing assembly difficulty and manufacturing costs. In applications, suitable snap-fit ​​structures, such as elastic clips or barbs, can be selected according to requirements, making it particularly suitable for scenarios requiring lightweight design or rapid assembly. This improves product economy and user experience while ensuring the reliability of conductive functions. Furthermore, at the end extending outwards from the connecting post 100, the mounting base 300 is provided with a wire channel 303, providing a direct path for the wire to the conductive post 210. This allows the wire connected to the conductive post 210 to smoothly pass into the mounting base 300 and reliably connect to the conductive post 210. Moreover, the directional opening of the wire channel 303 guides the wire along a predetermined path, shortening the connection distance between the wire and the conductive post 210, reducing line impedance and signal attenuation.

[0029] Refer to Figure 1In some embodiments of this utility model, a connecting seat 400 is snap-fitted onto the inner wall of the end of another connecting post 100. A circuit board 410 is mounted on the connecting seat 400, and multiple conductive rings 220 are disposed on the surface of the circuit board 410. By setting mounting seats 300 and connecting seats 400 at the ends of adjacent connections, the conductive post 210 and conductive rings 220 are respectively mounted on the mounting seats 300 and connecting seats 400, achieving centralized arrangement of the circuit at the splicing point. Similarly, like the mounting seat 300, the snap-fit ​​connecting seat 400 can be quickly fixed to the inner wall of the connecting post 100, simplifying the assembly process and improving production efficiency, while ensuring the relative positional accuracy of the connecting seat 400 and the connecting post 100, ensuring accurate correspondence between the conductive rings 220 and the conductive post 210. Furthermore, the circuit board 410, serving as the carrier of the conductive ring 220, orderly distributes the connection points of multiple wires through printed circuitry or soldering processes, achieving efficient conduction between the wires and the conductive ring 220. This avoids the problem of multiple wires crossing and tangling, improving the neatness and reliability of the circuit layout. After multiple conductive rings 220 are integrated through the circuit board 410, they can form a stable multi-path conductive system with the conductive posts 210, meeting the needs of simultaneously transmitting power, control signals, and other types of wires, suitable for complex equipment scenarios. For example, there are three conductive posts 210, located on the same side of the connecting post 100 and spaced apart radially from the connecting post 100. There are also three conductive rings 220, with gradually increasing diameters, arranged sequentially around each other to correspond one-to-one with the conductive posts 210. This ensures that each wire, such as the live wire, neutral wire, ground wire, or control signal wire, forms a stable path with the conductive ring 220 through an independent conductive post 210, improving the reliability of multi-wire conduction. It is understandable that the number of conductive posts 210 and conductive rings 220 can be further expanded according to actual functions, such as adding data transmission circuits, data control circuits, etc.

[0030] The column assembly according to an embodiment of the present invention includes an infinitely long splicing conductive structure according to an embodiment of the present invention. Utilizing the flexibility of threaded splicing, the number of connecting columns 100 can be freely increased or decreased as needed, breaking through the traditional fixed height limitation and meeting the usage requirements of diverse scenarios. The combination of a hollow structure and conductive design allows power lines, control lines, etc., to run from the bottom to the top of the column, avoiding the safety hazards of exposed wires and improving the aesthetics and environmental adaptability of the equipment. The reliable conductivity of the conductive columns 210 and conductive rings 220 ensures the continuity of the internal circuitry of the column after splicing, ensuring stable power supply or signal transmission for top functional components such as motors and sensors. It is suitable for equipment with high requirements for height adjustment and functional integration, such as floor fans and industrial lighting brackets, simplifying structural design while improving product reliability and user experience.

[0031] Other components and operations of the column assembly according to the embodiments of this utility model are known to those skilled in the art and will not be described in detail here.

[0032] The fan according to this utility model embodiment includes an infinitely long splicing conductive structure, which solves the problems of limited height adjustment range and difficult internal wiring in traditional fans. Users can flexibly adjust the overall height of the fan according to the actual environment, breaking through the fixed-gear limitations of traditional telescopic columns and improving applicability and space utilization. The hollow connecting column 100 and conductive design allow power cords, motor control wires, etc., to pass through from the base 500 to the fan head 620, avoiding wear, tangling, or electric shock risks caused by exposed wires. This is especially suitable for scenarios with high safety requirements, such as families with children or pets. This design integrates height adjustment, internal wiring, and conductive functions into the core structure of the fan, significantly improving the product's functionality, safety, and market competitiveness, providing users with a more convenient and reliable user experience.

[0033] Refer to Figures 3 to 6 The fan also includes a base 500, a fan head 600, a column assembly consisting of a single connecting post 100 or multiple connecting posts 100, and multiple conductive structures. The bottom end of the column assembly is mounted to and threadedly connected to the base 500, and the fan head 600 is mounted to and threadedly connected to the top end of the column assembly. It should be noted that the conductive structures can refer to the conductive post 210 and conductive ring 220 described above, and will not be elaborated upon here. Specifically, multiple conductive structures are respectively set at the screw connection between the base 500 and the column assembly, at the screw connection between adjacent connecting columns 100 among the multiple connecting columns 100, and at the screw connection between the column assembly and the machine head 600. Further, the base 500 is provided with a power supply interface and a drive wire connected to the power supply interface. The drive wire is connected to the conductive column 210 or the conductive ring 220. Similarly, the conductive column 210 is floating on the axis of the connecting column 100 so that when the base 500, the column assembly, and the machine head 600 are screwed together in sequence, the conductive column 210 and the conductive ring 220 press against each other and conduct electricity. The connecting column 100 is a hollow structure so that the conductive column 210 and the conductive ring 220 can be connected through the first wire.

[0034] To address this, the power supply interface is centrally located on the base 500, and a multi-level height adjustment is achieved using a hollow column assembly and threaded connection structure. Simultaneously, a floating conductive structure is incorporated at each connection node, resolving the issues of unsafe power supply and inflexible fixed height inherent in traditional fan heads 600. Users can precisely adjust the height of the fan head 600 by increasing or decreasing the number of hollow connecting columns 100 to suit different usage scenarios such as sitting, sitting in a chair, or standing. When the threads are tightened, the conductive column 210 and conductive ring 220 automatically press against each other for conductivity, avoiding the safety hazard of exposed power cables on the fan head 600 while ensuring continuous power supply from the base 500 through the hollow columns to the fan head 600. This simplifies the assembly process and improves the reliability of power transmission, achieving an integrated design of height adjustment and power supply safety. Through the synergistic effect of the hollow and conductive structures, the fan can adapt to diverse usage needs while ensuring electrical safety.

[0035] Optionally, in some embodiments of this utility model, the height of the connecting column 100 is A, satisfying 150mm≤A≤400mm, covering the height requirements of users in all scenarios from sitting to standing. The minimum adjustment setting of 150mm, using only a single connecting column 100, can meet the minimum height requirements for children or close-range airflow while sitting. The maximum adjustment setting of 400mm provides sufficient height increments to adapt to airflow coverage in standing or high-ceilinged spaces, laying a foundation for flexible adjustment for users of different heights and usage environments. This ensures precise overall height adaptation through the combination of connecting columns 100, enabling the fan to meet height adjustment needs in diverse scenarios, thus improving the fan's applicability and user satisfaction. In some embodiments of this utility model, the height is set to 250mm≤A≤300mm, precisely focusing on the medium height adjustment range most commonly used by users, such as the height difference between the leg area when sitting and the waist area when working on a desk. This makes the total height increment of the 100 adjacent connecting columns more in line with the comfortable range of human use, i.e., about 25cm-30cm per column. This avoids excessively large jumps in the total height after combination due to excessively high single columns or excessively low height, resulting in redundant adjustment levels. It significantly improves the accuracy and practicality of height adjustment, better matches the refined needs of air supply height in home and office scenarios, provides users with adjustment options that are more in line with daily usage habits, and optimizes the user experience.

[0036] Refer to Figure 3 In some embodiments of this utility model, a hollow first threaded post 510 is provided in the middle of the base 500 to provide a standardized bottom connection interface for the column assembly. This ensures that the drive wire can pass directly through the first threaded post 510 from inside the base 500 to the top connecting post 100 to form a continuous power supply path. It also achieves mechanical fixing and conductive structure docking simultaneously with the threaded connection of the column assembly, simplifying the assembly process of the base 500 and the column assembly.

[0037] Refer to Figure 4 In some embodiments of this utility model, the machine head 600 includes a base 610 and a fan head 620. The fan head 620 is mounted on the base 610. The base 610 has a hollow structure to allow the second wire connected to the conductive post 210 or conductive ring 220 to be connected to the fan head 620. The base 610 is provided with a second threaded post 611, and the top end of the column assembly is threadedly connected to the second threaded post 611. On the one hand, the threaded connection of the second threaded post 611 fixes the position of the machine head 600 and completes the electrical conduction, avoiding the exposure of the power line of the machine head 600. On the other hand, the hollow structure of the base 610 provides a sealed channel for the drive wire from the top end of the column assembly to the second wire of the fan head 620, so as to avoid the second wire being interfered with by the airflow when the fan head 620 is running.

[0038] Optionally, there are two conductive posts 210 and two conductive rings 220, each corresponding to one of the conductive posts 210, such as corresponding to the positive and negative terminals respectively. It should be noted that, as described above, the number of conductive posts 210 and conductive rings 220 can be further expanded according to actual functions, such as adding data transmission circuits, data control circuits, etc.

[0039] It should be noted that when the column group is configured as multiple connecting columns 100, the connection structure between adjacent connecting columns 100 can be referred to, which will not be elaborated here.

[0040] Other components and operations of the fan according to the embodiments of the present invention are known to those skilled in the art and will not be described in detail here.

[0041] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
