Detailed Implementation

[0018] like Figs. 1 to 3 As shown, a locking device for the large and small tubes of a floor fan column includes an upper tube body 10, a lower tube body 20, and a locking device 30. The upper tube body 10 is connected to the upper end of the locking device 30, and the lower tube body 20 is connected to the lower end of the locking device 30. In use, the upper tube body 10 is used to connect to the fan body, and the lower tube body 20 is used to connect to the fan base.

[0019] In practical implementation, the locking device 30 includes an inner sleeve 31, an outer sleeve 32, and a locking member 33. The outer sleeve 32 is fitted over the outer side of the inner sleeve 31. The lower end of the inner sleeve 31 is provided with a locking connection part 311. The side of the outer sleeve 32 is provided with a connecting groove 321, which is correspondingly positioned with the locking connection part 311. The upper end of the lower tube 20 is connected to the inner sleeve 31. One end of the locking member 33 passes through the connecting groove 321 and connects to the locking connection part 311, thereby allowing the lower tube 20 to be adjusted and fixedly connected to the lower end of the locking device 30. The upper end of the inner sleeve 31 is provided with a snap-fit ​​connection part 312, and the lower end of the upper tube 10 is snapped into the snap-fit ​​part 312. The upper tube 10 is connected to the upper end of the locking device 30 via the connecting part 312. During use, the user can loosen the locking member 33 by screwing it to release the locking state. At this time, the lower tube 20 can slide up and down relative to the inner part 31 to adjust the overall height of the lower tube 20. After the lower tube 20 moves to the target height position, the user screws the locking member 33 to tighten it, so that the locking member 33 is connected to the locking connecting part 311 through the connecting groove 321 and tightened, thereby firmly locking the lower tube 20 to the lower end of the locking device 30 and preventing it from continuing to slide. The adjustment process is convenient and quick, and the connection is stable and reliable after locking. It meets the height adjustment function under different usage requirements. The structure is simple and easy to assemble.

[0020] In specific implementation, the locking connection part 311 is provided with a first locking through part 311a and a second locking through part 311b, which are oppositely arranged between the first locking through part 311a and the second locking through part 311b. One end of the locking piece 33 is connected with a connecting stud 331. The side surface of the second locking through part 311b is recessed with a polygonal nut recess 311c, in which a connecting nut 332 adapted to the connecting stud 331 is embedded. The connecting stud 331 passes through the first locking through part 311a and the second locking through part 311b in sequence, and is threadedly connected and fixed between the end of the connecting stud 331 and the connecting nut 332. In use, the user rotates the locking piece 33 to drive the connecting stud 331 to rotate. Since the connecting nut 332 is fixed in the nut recess 311c and cannot rotate, the connecting stud 331 pushes the first locking through part 311a and the second locking through part 311b to tighten towards each other during the process of screwing into the connecting nut 332. The relative tightening of the first locking through part 311a and the second locking through part 311b exerts a radial clamping force on the lower pipe body 20, achieving firm locking. If the height of the lower pipe body 20 needs to be adjusted, the locking structure can be loosened by reversing the rotation of the locking piece 33, and the sliding adjustment of the lower pipe body 20 can be performed. The structure is convenient to operate and adjust quickly without the need for additional tools. The user can complete the height adjustment and locking fixation manually.

[0021] In specific implementation, the outer side surface of the clamping connection part 312 is uniformly provided with a plurality of upper pipe clamping blocks 312a. When the upper pipe body 10 is connected to the clamping connection part 312, the plurality of upper pipe clamping blocks 312a are clamped and connected between the inner side wall of the upper pipe body 10. The lower part of the clamping connection part 312 is provided with a fixing through slot 312b, and the lower side surface of the upper pipe body 10 is provided with a fixing through hole 11. The fixing through hole 11 corresponds to the fixing through slot 312b and is connected and fixed by a fastener passing through the fixing through hole 11 and the fixing through slot 312b, so that the upper pipe body 10 is fixed and clamped to the upper end of the locking device 30. In use, the upper pipe body 10 can be quickly clamped and stably installed at the upper end of the locking device 30. The overall structure design is simple, the operation is simple, and the installation efficiency is high. At the same time, the dual mode of clamping connection and screwing fixation effectively enhances the connection strength, and is suitable for application scenarios such as fan columns with high requirements for structural stability.

[0022] In summary, the outer sleeve 32 is sleeved on the outside of the inner sleeve 31, the lower end of the inner sleeve 31 is provided with a locking connecting part 311, the side of the outer sleeve 32 is provided with a connecting through slot 321, the connecting through slot 321 and the locking connecting part 311 are correspondingly arranged, the upper end of the lower pipe body 20 is connected in the inner sleeve 31, one end of the locking part 33 is connected with the locking connecting part 311 through the connecting through slot 321, so that the lower pipe body 20 is adjustably and fixedly connected with the lower end of the locking device 30, the upper end of the inner sleeve 31 is provided with a clamping connecting part 312, the lower end of the upper pipe body 10 is clamped on the clamping connecting part 312, so that the upper pipe body 10 is connected with the upper end of the locking device 30, the adjusting process of the floor fan stand column size pipe locking device is convenient and fast, the connection is stable and reliable after locking, the height adjusting function under different use requirements is met, the structure is simple, and the assembly is convenient and stable.
