Problems solved by technology

[0002] When adjusting the height of the existing floor-standing electric fans, the plastic cards on both sides of the fan are opened by both hands, and then the electric fan is moved upward or downward with force. The meshing part between the slots on the fan is small, and after a long time, it is prone to slipping, or even completely fails, so that the height of the electric fan cannot be adjusted, the reliability is poor, and the service life is short

Embodiment Construction

[0008] see Figure 1 to Figure 2 , the present invention includes a fan 1 and a bracket 2, fan ears 11 are symmetrically arranged on the left and right sides of the fan 1, guide posts 21 are symmetrically arranged on the left and right sides of the bracket 2, and the two fan ears A screw 3 is also installed in the inner holes of 11, and a plurality of taper holes 211 with equal spacing are arranged on the sides of the two guide posts 21, and the screw 3 is provided with a thread corresponding to the inner thread of the fan ear 11. Matching external threads 31, and a tapered pin 32 is provided at the head of the screw 3. The taper of the taper pin 32 at the head of the screw 3 is the same as the taper of the taper hole 211 of the guide post 21 .

[0009] When adjusting, first loosen the screws 3 on both sides of the fan, and then, after moving the fan 1 to a suitable height, screw the screws 3 into the tapered holes of the guide post 21 of the bracket to lock them.

Abstract

The invention discloses a height adjustment device for a floor type electric fan. The height adjustment device for the floor type electric fan comprises a fan (1) and a support (2). Fan ears (11) are symmetrically arranged on the left side and the right side of the fan (1), and guide pillars (21) are symmetrically arranged on the left edge and the right edge of the support (2). Two bolts (3) are respectively arranged in inner holes of the two fan ears (11), and a plurality of taper holes (211) which are arranged at equal intervals are formed in the side face of each guide pillar (21). Each bolt (3) is provided with outer threads (31) which are matched with inner threads of the corresponding fan ear (11), and the head of each bolt (3) is provided with a taper pin (32). The conical degree of the taper pin (32) of the head of each bolt (3) is the equal to that of the taper hole (211) of each guide pillar (21). The height adjustment device for the floor type electric fan disclosed by the invention is simple in structure, stable and reliable, convenient to adjust, and long in service life.

Description

technical field [0001] The invention relates to a fan, in particular to a height adjusting device for a floor-standing electric fan. Background technique [0002] When adjusting the height of the existing floor-standing electric fan, the plastic cards on both sides of the fan are opened by both hands, and then the electric fan is moved upward or downward with force. The meshing part between the grooves on the fan is relatively small. After a long time, it is prone to slippage, or even completely fails, so that the height of the electric fan cannot be adjusted, the reliability is poor, and the service life is short. Contents of the invention [0003] The object of the present invention is to provide a floor-standing electric fan height adjustment device with simple structure, stable and reliable, convenient adjustment and long service life. [0004] In order to achieve the above object, the present invention includes a fan and a bracket. Fan ears are symmetrically arranged...
