[0035] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0036] The following disclosure provides numerous different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0037] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0038] like Figures 1 to 5 As shown, in a first aspect, this application provides a support mechanism, including: a connecting frame 10, a plurality of first tubular structures 20 and a plurality of second tubular structures 30; the plurality of first tubular structures 20 are movably connected to the connecting frame 10 respectively; the plurality of second tubular structures 30 are arranged in a one-to-one correspondence with the first tubular structures 20, the second tubular structures 30 are slidably inserted inside the first tubular structures 20, and the end of the second tubular structure 30 near the connecting frame 10 can be locked to both ends of the first tubular structure 20 respectively, the locking state being magnetic locking and / or threaded locking.

[0039] The second tubular structure 30 enables telescopic functionality through different locking states at both ends, employing magnetic and / or threaded locking. Adjustments are made simply by rotating or pulling the second tubular structure, eliminating the need to press the elastic structure or snap-fit, making adjustments more convenient for the user. This application effectively solves the problem in existing technologies where the telescopic adjustment of support mechanisms relies on spring-loaded balls or snap-fit ​​mechanisms, leading to relatively difficult adjustments and negatively impacting the user experience.

[0040] It should be noted that when multiple positions are locked in a threaded state, stepless adjustment can be achieved through the self-locking of the threads, meaning that the locked position can be finely adjusted. This setting has a wider adjustment range and is more practical.

[0041] Furthermore, when the thread is locked, a scale for adjusting the rotation angle can be set between the first tubular structure 20 and the second tubular structure 30 so that the adjustments of multiple first tubular structures 20 and second tubular structures 30 can be matched, making the overall placement more stable.

[0042] like Figure 4 As shown, in this embodiment, a detachable first locking member 21 is fixedly provided at one end of the first tubular structure 20 near the connecting frame 10, and a detachable second locking member 31 is fixedly provided at one end of the second tubular structure 30 near the connecting frame 10. The first locking member 21 and the second locking member 31 can be magnetically connected to form a magnetic lock. In the retracted state, the first tubular structure 20 and the second tubular structure 30 are magnetically locked by the first locking member 21 and the second locking member 31 located at the end near the connecting frame 10. This arrangement allows for direct locking during retraction, i.e., the two are magnetically attracted without the need for fine adjustments, making retraction convenient. At the same time, the magnetic attraction is less likely to fall off, resulting in a good locking effect.

[0043] Furthermore, in the technical solution of this embodiment, the first locking member 21 is made of a ferromagnetic metal or a magnetic material, and the second locking member 31 is made of a magnetic material. The second locking member 31 is made of a magnetic material, which allows it to lock after the second tubular structure 30 extends or retracts, resulting in better adaptability. Simultaneously, the second locking member 31 can also be used for other magnetic attraction requirements, not limited to the position of the first locking member 21. In a specific embodiment, the first locking member 21 is preferably made of a ferromagnetic metal. This arrangement helps to reduce magnetism at the end near the connecting frame 10, avoiding direct impact on the components and circuits mounted on the connecting frame 10.

[0044] In an alternative embodiment, one or more third locking elements are provided on the inner wall of the first tubular structure 20. The third locking elements are made of a ferromagnetic metal material, and they are magnetically connected to the second locking element 31 to form a magnetic lock. This arrangement allows for multiple mating positions between the first tubular structure 20 and the second tubular structure 30, enabling multi-level adjustment. This arrangement is based on the movable second locking element 31. Specifically, the third locking element is a surrounding metal ring that can be attracted by a magnet. The outer periphery of the second locking element 31 is gap-fitted with the metal ring. When the second locking element 31 is located inside the metal ring, the metal ring and the second locking element 31 generate a magnetic attraction, thereby achieving locking.

[0045] Based on the above-mentioned alternative embodiments, a specific embodiment can be extended, in which multiple magnetic structures similar to the second locking member 31 are sequentially arranged along the axial direction of the second tubular structure 30 to adapt to the metal rings at multiple positions. Such an arrangement can form a damping effect during the adjustment process, enabling locking at multiple positions, making the locking between the first tubular structure 20 and the second tubular structure 30 more reliable and stable, and the adjustment range is also wider.

[0046] like Figures 3 to 5 As shown in the technical solution of this embodiment, a detachable fourth locking member 22 is provided at the end of the first tubular structure 20 away from the connecting frame 10, and a detachable fifth locking member 32 is fixedly provided at the end of the second tubular structure 30 near the connecting frame 10. The fifth locking member 32 and the fourth locking member 22 can be threadedly connected to form a threaded lock. The fourth locking member 22 and the fifth locking member 32 are provided to form a lock in the tensile state. The threaded lock provides a better locking effect and can form a self-locking in the axial direction, preventing retraction after tension. It is suitable for positions requiring rigid support. The threaded lock can be set to a longer thread pair to facilitate fine-tuning with higher precision. In practical applications, it can be used for leveling work.

[0047] like Figure 3 , Figure 7 and Figure 8 As shown, in this embodiment, the fourth locking member 22 includes a first cylindrical wall 221 and a plurality of first limiting blocks 222. The plurality of first limiting blocks 222 are respectively connected to the outer periphery of the first cylindrical wall 221. The first tubular structure 20 is provided with first mounting holes 23 corresponding to the plurality of first limiting blocks 222. The first cylindrical wall 221 is clearance-fitted with the inner wall of the first tubular structure 20, and the first limiting blocks 222 can be inserted into the first mounting holes 23 to form a fixed connection. The first limiting blocks 222 are provided to achieve a snap-fit ​​connection with the first tubular structure 20. Specifically, the first limiting blocks 222 are installed in the first mounting holes 23 to achieve a limiting and fixed connection.

[0048] Furthermore, such as Figures 3 to 5 as well as Figure 7 As shown, in this embodiment, there are two first limiting blocks 222, symmetrically arranged on the periphery of the first cylindrical wall 221 to form a symmetrical limiting position. The first limiting blocks 222 extend into the first tubular structure 20 from the end near the second tubular structure 30, and the distance between the first cylindrical wall 221 and the first limiting blocks 222 gradually increases along the direction in which the fourth locking member 22 extends, thus facilitating assembly. The fourth locking member 22 is also provided with a first limiting boss 223, the circumferential dimension of which is larger than that of the first tubular structure 20. This arrangement ensures that after the first cylindrical wall 221 enters the first tubular structure 20, its axial freedom is restricted by the first limiting boss 223, and its circumferential rotation or sliding freedom is restricted by the first limiting blocks 222. The structure is more compact, and assembly is more convenient as the first limiting blocks 222 can be directly pushed into the first tubular structure 20.

[0049] like Figure 3 , Figure 9 and Figure 10 As shown, in this embodiment, the fifth locking member 32 includes a second cylindrical wall 321 and a plurality of second limiting blocks 322. The plurality of second limiting blocks 322 are respectively connected to the inner cavity of the second cylindrical wall 321. The second tubular structure 30 is provided with second assembly holes 33 corresponding to the plurality of second limiting blocks 322. The second cylindrical wall 321 and the outer periphery of the second tubular structure 30 are clearance-fitted, and the first limiting block 222 can be inserted into the second assembly hole 33 to form a fixed connection. The second limiting block 322 is provided to achieve a snap-fit ​​connection with the second tubular structure 30. Specifically, the second limiting block 322 is installed in the second assembly hole 33 to achieve a limiting and fixed connection.

[0050] Furthermore, such as Figures 3 to 5 as well as Figure 9As shown, in this embodiment, there are two second limiting blocks 322, symmetrically arranged on the inner circumference of the second cylindrical wall 321 to form symmetrical limiting positions. The second limiting blocks 322 are inserted into the second tubular structure 30 from the end closest to it, and the distance between the second cylindrical wall 321 and the second limiting blocks 322 gradually increases along the direction in which the fifth locking member 32 extends, facilitating assembly. The fifth locking member 32 is also provided with a second limiting boss 323, the circumferential dimension of which is larger than that of the second tubular structure 30. This arrangement allows the second cylindrical wall 321 to be fitted onto the circumference of the second tubular structure 30, with the second limiting boss 323 restricting its axial freedom and the second limiting blocks 322 restricting its circumferential rotation or sliding freedom. The structure is more compact, and assembly is more convenient as the second limiting blocks 322 are simply fitted onto the second tubular structure 30.

[0051] It should be noted that the fifth locking component 32 and the fourth locking component 22 have similar structures. Both are achieved by setting the required connection points on the side wall of the installation position, in conjunction with the drilling of the pipe. This assembly method is more convenient; simply push in the limiting block. It can also be disassembled and assembled during storage to effectively integrate multiple components, making it more suitable for outdoor scenarios. The fourth locking component 22 and the fifth locking component 32 also form a mutual limiting mechanism, preventing the first tubular structure 20 and the second tubular structure 30 from separating and falling off.

[0052] like Figure 4 , Figure 5 , Figure 7 and Figure 9 As shown, in this embodiment, the inner wall of the first cylindrical wall 221 forms an internal thread, and the outer periphery of the second cylindrical wall 321 forms an external thread, with the internal and external threads being compatible. The combination of internal and external threads creates a tight threaded pair, enabling self-locking and fine-tuning, suitable for the needs of complex outdoor environments. The adjustable range can be set by the specific lengths of the internal and external threads.

[0053] In this embodiment, the second locking member 31 is fixedly disposed within the inner cavity of the second cylindrical wall 321 and located on the side of the second limiting block 322 near the first tubular structure 20. This arrangement allows one end of the second locking member 31 to contact or be separated from the second limiting block 322, and the second locking member 31 can also extend out of the inner cavity of the second cylindrical wall 321, enabling the second limiting block 322 to form a limit, preventing it from sliding out along the inner cavity of the second cylindrical wall 321. This results in a more compact structure and higher assembly precision.

[0054] like Figures 4 to 6As shown, in this embodiment, the first tubular structure 20 further includes a connector 24. The first end of the connector 24 is rotatably connected to the connecting frame 10, and the second end of the connector 24 is provided with a mounting cavity 241. A first locking member 21 is located within the mounting cavity 241. The connector 24 is used to connect the first tubular structure 20 to the connecting frame 10. The rotatable connection allows for adjustment of the orientation of the first tubular structure 20, providing a wider range of motion.

[0055] It should be noted that the connector 24 has a mounting cavity 241 at the end near the first tubular structure 20 for mounting the first locking member 21. The connector 24 also has a third limiting boss 242, which prevents the connector 24 from getting stuck in the first tubular structure 20 and avoids it from becoming jammed inside the cavity. Specifically, the connector 24 is connected to the connecting frame 10 via a connecting piece 243, allowing the connector 24 to rotate around the through hole on the connecting piece 243, thereby enabling angle adjustment of the first tubular structure 20 and the second tubular structure 30.

[0056] In an alternative embodiment (not shown in the figure), the support mechanism includes a third tubular structure that is slidably inserted inside the second tubular structure 30, and the end of the third tubular structure near the connecting frame 10 can be locked to both ends of the second tubular structure 30. The third tubular structure is provided to further extend and support the connecting frame 10, resulting in a structure with stronger load-bearing capacity and better suited for mounting high-power electrical appliances.

[0057] Furthermore, in an alternative embodiment, the first tubular structure 20 and the second tubular structure 30 are symmetrically arranged at both ends of the third tubular structure. This arrangement makes the connected tubular structures symmetrical, resulting in higher structural strength. Furthermore, it eliminates the need to consider the need for multiple nested tubular structures during storage. This ensures higher structural strength, making it suitable for more complex scenarios, while the symmetrical structural arrangement enhances the strength of the support mechanism and reduces the possibility of damage during outdoor use.

[0058] In a specific embodiment of this application, the support mechanism includes a connecting frame 10, a first tubular structure 20, a first locking member 21, a fourth locking member 22, a first cylindrical wall 221, a first limiting block 222, a first limiting boss 223, a first assembly hole 23, a connecting member 24, a mounting cavity 241, a third limiting boss 242, a connecting piece 243, a second tubular structure 30, a second locking member 31, a fifth locking member 32, a second cylindrical wall 321, a second limiting block 322, a second limiting boss 323, a second assembly hole 33, and a sealing member 34.

[0059] The fourth locking member 22 is inserted into the mounting cavity 241 of the connector 24 on the first tubular structure 20. The first limiting block 222 on the fourth locking member 22 is fixed in the first assembly hole 23 on the first tubular structure 20. At this time, the first tubular structure 20 with the fourth locking member 22 installed forms an upper tube assembly.

[0060] The fifth locking member 32 is installed on the second tubular structure 30, and then the second limiting boss 323 on the fifth locking member 32 is assembled with the second mounting hole 33 on the second tubular structure 30. The fifth locking member 32 is then installed on the second tubular structure 30, and the second locking member 31 is installed on the fifth locking member 32 and secured. The sealing member 34 is then inserted into the second tubular structure 30. The second tubular structure 30, with the fifth locking member 32 and the sealing member 34 installed, forms a lower tube assembly.

[0061] Starting from the position where the sealing member 34 is installed on the second tubular structure 30, insert the lower tube assembly into the center of the first tubular structure 20 from the position away from the third limiting boss 242. Continue to push the lower tube assembly into the center of the first tubular structure 20, and push the sealing member 34 on the second tubular structure 30 through the center of the fourth locking member 22 already installed on the first tubular structure 20. This will allow the lower tube assembly to pass through the upper tube assembly. At this time, the fifth locking member 32 installed on the second tubular structure 30 will be blocked by the fourth locking member 22, thus limiting the lower tube assembly in the upper tube assembly and preventing it from coming out.

[0062] A magnetic second locking member 31 is installed in the mounting cavity 241 of the connector 24 to form an upper cap assembly. The upper cap assembly is effectively fixed in any direction during the height adjustment process by the outer shell wall of the connector 24 and the first tubular structure 20 through clearance fit, so that the entire lower tube assembly can be effectively fixed in any direction and cannot fall off.

[0063] Working principle:

[0064] An adjustable height tripod for outdoor fans allows for length adjustment by manually rotating the lower tube clockwise. This engages the fifth locking element 32 with the fourth locking element 22, creating a tight seal between the first and second tubular structures 20 and 30.

[0065] The fifth locking member 32 and the fourth locking member 22 are screwed together to fix the first tubular structure 20 and the second tubular structure 30, thereby satisfying the fixed adjustment of the height. When it is necessary to shorten the length of the tripod, manually rotate the lower tube counterclockwise to disengage the fifth locking member 32 from the fourth locking member 22, push the lower tube assembly towards the connecting frame 10, and make the first locking member 21 and the second locking member 31 magnetically attract and fix it, thereby completing the shortening and adjustment of the height, and at the same time completing the storage.

[0066] It should be noted that the first locking member 21 and the second locking member 31 include, but are not limited to, one of them being made of metal or other materials with adsorption properties; this solution can also be used.

[0067] When using threaded locking, this scheme can be adopted regardless of whether the thread rotation direction of the fifth locking member 32 and the fourth locking member 22 is clockwise or counterclockwise.

[0068] Secondly, this application provides a fan, which includes a fan head and a support mechanism. The support mechanism is the same as that described in the above embodiments, and the fan head is detachably connected to the connecting frame 10 of the support mechanism. Using the above-described support mechanism, the height and angle adjustment of the fan can better adapt to complex placement environments and can be effectively adjusted to adapt to different ground heights, making the outdoor fan application more effective and improving the user experience.
