[0025] To make the objectives, technical solutions, and advantages of this application more clearly understood, the embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be noted that, unless there is a conflict, the embodiments and features in the embodiments of this application can be combined with each other in any manner. Those skilled in the art will appreciate that the column connection structure of this application is suitable for connecting main bodies, especially columns of household appliances such as fans.

[0026] like Figure 1-5 As shown, a column connection structure of the present application includes a first connecting post 3, a second connecting post 4 and a pressing piece 5. Among them, one end of the pressing piece 5 is set on the second connecting post 4, and can elastically reciprocate with the connection point of the second connecting post 4 as a fulcrum; the other end of the pressing piece 5 is provided with a limiting portion; further, a positioning portion is provided on the first connecting post 3; specifically, the first connecting post 3 can be plugged together with the second connecting post 4 so that the limiting portion and the positioning portion are detachably connected together. By adopting the above scheme, the limiting portion and the positioning portion at the other end of the pressing piece 5 can be separated from each other by pressing the pressing piece 5, thereby realizing the disassembly and assembly of the first connecting post 3 and the second connecting post 4. The column connection structure designed in the present application, by directly setting the pressing piece on the second connecting post and using the second connecting post as a supporting structure, makes the pressing process of the entire pressing piece more stable, the structure more reliable, and can be quickly disassembled and assembled, with high disassembly and assembly efficiency.

[0027] like Figure 1-5As shown, in some embodiments, the limiting portion is designed as a hook 52, and correspondingly, the positioning portion is designed as a slot 31. The hook 52 can be adapted to the slot 31 to achieve a detachable connection. Alternatively, the limiting portion can be designed as a slot 31, and the positioning portion can be designed as a hook 52, which can also be applied to the structure of the present application.

[0028] like Figure 2-5 As shown, in some embodiments, the column connection structure further includes an elastic member 6, and the pressing member 5 is provided with a button 51. Specifically, one end of the pressing member 5 is provided with a connecting portion 51, and the connecting portion 51 is rotatably connected to the second connecting post 4. This allows one end of the pressing member 5 to rotate on the second connecting post 4 via the connecting portion 51. Furthermore, one end of the elastic member 6 is disposed on the second connecting post 4, and the other end of the elastic member 6 abuts against the button 51. This allows the pressing member 5 to reset during the pressing and rotating process, resulting in a relatively compact and rational structural design.

[0029] like Figure 2-5 As shown, in some embodiments, the elastic member 6 is preferably a spring. Specifically, a positioning post is provided on the inner wall of the second connecting post 4, and a positioning slot is provided on the inner wall of the pressing member 5. The positioning slot is located on the back of the button 51. Specifically, one end of the spring is sleeved on the positioning post, and the other end of the spring is disposed in the positioning slot, thereby propping up the pressing member 5. In other words, the spring can lift the pressing member 5 in its natural state, so that the hook 52 on the pressing member 5 is precisely engaged with the slot 31. This prevents uneven force from causing the hook 52 to loosen from the slot 31.

[0030] like Figure 2-5 As shown, in some embodiments, the column connection structure provided by the present application also includes power terminals, which include a first power terminal 7 and a second power terminal 8. The first power terminal 7 is arranged on the side wall of the first terminal 3, preferably on the rear side wall of the first terminal 3, and the card slot 31 is arranged on the front side wall of the first terminal 3. Correspondingly, the second power terminal 8 is arranged on the side wall of the second terminal 4; preferably on the rear side wall of the second terminal 4. In the above scheme, by arranging the power terminals on the side walls of the terminals, it is convenient to repair or replace. Specifically, the first terminal 3 and the second terminal 4 are plugged together so that the first power terminal 7 and the second power terminal 8 are plugged together, thereby realizing power connection; when the first terminal 3 and the second terminal 4 are disassembled and separated, the first power terminal 7 and the second power terminal 8 are separated from each other, and the power is disconnected.

[0031] like Figure 5 、 Figure 8-Figure 9As shown, in some embodiments, a mounting cover 9 is provided within the first post 3, and a mounting slot 91 is provided within the mounting cover 9. A claw 92 is provided on the side of the mounting cover 9. This design allows the first electrical terminal 7 to be fixedly mounted within the mounting slot 91, and the mounting cover 9 can be engaged with the inner sidewall of the first post 3 via the claw 92. Furthermore, a clamping portion is provided on the first electrical terminal 7, and the first electrical terminal 7 is engaged with the inner wall of the first post 3 via the clamping portion, thereby securing the terminal and preventing it from loosening or falling off during assembly or disassembly.

[0032] like Figure 6-7 As shown, in some embodiments, a slide groove 32 is provided on at least one side of one end of the first connecting post 3, and a slide rail 41 is provided on at least one side of one end of the second connecting post 4. Specifically, the slide rail 41 is slidably connected to the slide groove 32 to allow the first connecting post 3 and the second connecting post 4 to be plugged together. Specifically, the slide groove 32 is provided only on one side of one end of the first connecting post 3, and the slide rail 41 is provided only on one side of one end of the second connecting post 4. The slide groove 32 and the slide rail 41 are compatible and have a single assembly direction, which can provide a foolproof function.

[0033] like Figure 6-7 As shown, in some embodiments, a first connecting post 3 has two sides with different slide grooves 32 on one end, and the slide grooves 32 on both sides have different structures, specifically different sizes. Furthermore, a second connecting post 4 has two sides with different slide rails 41 on one end, and the slide rails 41 on both sides have different structures, specifically different sizes. In the above structural design, the slide groove 32 on one side of the first connecting post 3 is adapted to the slide rail 41 on one side of the second connecting post 4, thereby achieving a sliding connection; the slide groove 32 on the other side of the first connecting post 3 is adapted to the slide rail 41 on the other side of the second connecting post 4, thereby achieving a sliding connection. The solution provided in this embodiment, by designing slide grooves and slide rail structures of different sizes, ensures that the first and second connecting posts have a unique assembly direction, thus providing a fool-proof function.

[0034] like Figure 5-8 As shown, in some embodiments, the column connection structure further includes an upper column 1 and a lower column 2, and the upper column 1 and the lower column 2 are respectively tubular structures. Specifically, the first connecting column 3 is arranged in the upper column 1; the lower column 2 is provided with a through hole 21, and the second connecting column 4 is arranged in the lower column 2, and the button 51 on the pressing member 5 extends out of the through hole 21. With the above scheme, the first connecting column 3 on the upper column 1 and the second connecting column 4 on the lower column 2 can be plugged together to achieve the docking of the upper column 1 and the lower column 2, and at the same time, the first connecting column 3 and the second connecting column 4 are hidden in the upper column 1 and the lower column 2, and the structure is relatively compact. The first connecting column 3, the second connecting column 4 and the pressing member 5 designed in this application are respectively plastic parts, so that the pressing member 5 has a certain elasticity and is convenient for connection.

[0035] like Figure 10As shown, the present application also provides a fan, which includes the column connection structure 20 as described above. Specifically, the fan includes a fan head 10 and a chassis 30, and the fan head 10 and the chassis 30 are connected by the column connection structure 20. Furthermore, the column connection structure 20 can include multiple ones to achieve multi-level connection and disassembly, thereby improving the fan experience. The fan provided in the present application can be disassembled when the fan is stored, which is convenient for storage and transportation.

[0036] The column connection structure and fan proposed in this application have the following technical advantages:

[0037] (1) The column connection structure proposed in the present application forms a pressing fulcrum by designing a pressing member on the second connecting column, so that the entire pressing member is more stable to use and has a more reliable structure, can be quickly disassembled and assembled, and has a high disassembly and assembly efficiency.

[0038] (2) The column connection structure proposed in the present application is such that the first power terminal is arranged on the side wall of the first column and the second power terminal is designed on the side wall of the second column, which facilitates docking and installation, solves the problem of power connection and disconnection, and is convenient for maintenance and replacement.

[0039] (3) The column connection structure proposed in this application is convenient for plugging in and has an anti-mock function by designing a slide groove and a slide rail structure on the first connecting column and the second connecting column.
