[0029] See also Figure 2-4 The hanging rail pulley structure includes a pulley assembly 20 and a hanging rail unit 10. The pulley assembly 20 includes a pulley bracket 21 and a pulley group 22 arranged on both sides of the pulley bracket 21. The pulley bracket 21 is used to connect the fan body; the hanging rail unit 10 is suspended with a track 131 extending from the middle to both sides, and the pulley group 22 slides in the track 131; wherein, a transmission cavity 101 for accommodating a linkage structure is formed between two adjacent hanging rail units 10.

[0030] See also Figure 5 The hanging rail unit 10 in this scheme is changed from an inverted U-shape to an inverted T-shape, so that a transmission cavity 101 can be formed between two adjacent hanging rail units 10, and the pulley assembly 20 slides on the rails 131 on both sides of the hanging rail unit 10, which can not only achieve stable sliding, but also provide an installation position for the linkage structure. When the linkage structure transmits and connects two adjacent pulley assemblies 20, it only needs to pass through the transmission cavity 101, and there is no need to retain a gap between the hanging rail unit 10 and the fan body profile, which can make the installation appearance between the hanging rail unit 10 and the fan body more beautiful; at the same time, the pulley assembly 20 and the linkage structure are completely accommodated in the hanging rail unit 10, which is convenient for the early assembly of the hanging rail pulley structure and the linkage structure.
