To facilitate understanding of those skilled in the art, the present invention will be described in further detail with reference to specific embodiments and drawings.

A preferred embodiment of the present invention is as follows.

Referring to fig. 1 to 4, a floor fan convenient for height adjustment includes a fan body 1, an adjusting rod 2 fixedly connected to the fan body 1, a base 4, and a vertical rod 3 fixedly connected to the base 4, wherein the adjusting rod 2 and the vertical rod 3 are both hollow structures, and the adjusting rod 2 is sleeved outside the vertical rod 3; still include adjusting device 5, adjusting device 5 includes mount 51 and flexible glue cover 52, mount 51 and pole setting 3 fixed connection, flexible glue cover 52 cover locate on mount 51 and rotate with mount 51 and be connected, be equipped with extruded article 6 between flexible glue cover 52 and the mount 51, flexible glue cover 52 and the inner wall butt of adjusting pole 2, extruded article 6 can strut flexible glue cover 52 when adjusting pole 2 and rotate. In the embodiment, the adjusting rod 2 is manually rotated when in use, due to the friction force, the adjusting rod 2 can simultaneously drive the soft rubber sleeve 52 to rotate when rotating, the soft rubber sleeve 52 can be propped open by the extrusion piece 6 when rotating, and the fit between the soft rubber sleeve 52 and the adjusting rod 2 is interference fit so as to support and fix the adjusting rod 2; when the adjusting rod 2 rotates reversely, the extrusion piece 6 can withdraw the extrusion of the soft rubber sleeve 52, so that the soft rubber sleeve 52 and the adjusting rod 2 are in clearance fit, and the adjusting rod 2 can slide relative to the vertical rod 3 to adjust the height of the floor fan. This embodiment is through corotation or the mode of reversal regulation pole 2 to change flexible glue cover 52 and adjust the cooperation form between the pole 2, thereby realize adjusting the slip or fixed of pole 2, compare in traditional floor fan, its altitude mixture control need not lock through bolt or lock sleeve, makes the altitude mixture control of floor fan more simple convenient.

Referring to fig. 3 and 4, in the present embodiment, the extrusion member 6 includes an extrusion block 61 and a framework 62, the extrusion block 61 is fixedly connected to the fixing frame 51, the framework 62 is fixedly connected to the soft rubber sleeve 52, one surface of the framework 62 opposite to the extrusion block 61 has an arc surface, and the extrusion block 61 abuts against the arc surface. The distance between the arc-shaped surface and the end of the pressing block 61 is gradually reduced or increased along the arc of the arc-shaped surface. Specifically, the end of the pressing block 61 is the end of the pressing block 61 close to the fixed frame 51, and the end of the pressing block 61 far from the fixed frame 51 contacts with the arc-shaped surface of the framework 62. When the adjusting rod 2 rotates, the soft rubber sleeve 52 and the framework 62 are driven to rotate at the same time, and when the framework 62 rotates, the extrusion block 61 can gradually increase or reduce the extrusion on the arc surface. The principle is the same as that of the cam mechanism.

The concrete expression is as follows: referring to fig. 4, when the adjusting lever 2 rotates clockwise, one end of the extruding block 61 close to the fixing frame 51 gradually moves away from the framework 62, so that the extrusion of the extruding block 61 on the framework 62 and the soft rubber sleeve 52 is reduced until the extrusion of the extruding block 61 on the framework 62 and the soft rubber sleeve 52 is cancelled, at this time, the soft rubber sleeve 52 and the inner wall of the adjusting lever 2 are in clearance fit, and the adjusting lever 2 can slide relative to the upright rod 3, thereby realizing the adjustment of the height of the floor fan. When adjusting pole 2 anticlockwise rotation, the one end that extrusion piece 61 is close to mount 51 is close to skeleton 62 gradually, and extrusion piece 61 increases the extrusion power to skeleton 62 and flexible glue cover 52 gradually, and the cooperation of flexible glue cover 52 and the 2 inner walls of regulation pole is interference fit this moment, and it is fixed for pole setting 3 to adjust pole 2 to the realization is adjusted the locking of pole 2.

Referring to fig. 3, in the present embodiment, the soft rubber sleeve 52 is two semicircular rubber sleeves, and the extrusion member 6 is two corresponding to the two semicircular rubber sleeves. The arrangement of the two semicircular rubber sleeves and the extrusion piece 6 can effectively improve the support stability and the balance of the adjusting rod 2.

Referring to fig. 3, in the present embodiment, a tooth-shaped stripe 521 is disposed on a surface of the soft rubber sleeve 52 contacting with the inner wall of the adjusting lever 2. The toothed stripe 521 is arranged to enhance the friction between the inner wall of the adjusting lever 2 and the soft rubber sleeve 52, so that the adjusting lever 2 can ensure to drive the soft rubber sleeve 52 to rotate at the same time when rotating, thereby ensuring the use effect of the extrusion piece 6 and the soft rubber sleeve 52.
