Description

Technical Field

[0001] This utility model relates to a fan, and more particularly to a floor fan. Background Technology

[0002] The existing technology, Chinese patent 201510823595.5, discloses a floor fan and its upper tube fixing structure. The upper tube fixing structure includes: a fan rear shell with an inner cavity for inserting the upper tube; a limiting member for fixing the upper tube, the limiting member having external threads; and a threaded hole at the bottom of the side plate of the fan rear shell for inserting the limiting member and engaging with the external threads, the threaded hole communicating with the inner cavity. This invention discloses a floor fan upper tube fixing structure that, by providing a threaded hole at the bottom of the side plate of the fan rear shell, achieves a threaded engagement between the fan rear shell itself and the limiting member, eliminating the need for an additional nut and effectively preventing nut from falling off. This facilitates the connection between the fan rear shell and the upper tube, improving the performance of the floor fan. Simultaneously, it reduces the number of parts, lowers the cost of the floor fan, and improves assembly efficiency.
