Embodiment, belongs to the scope of protection of the invention.
Refer to Fig. 1-4, a kind of embodiment that the present invention is provided：A kind of electric fan rotating shaft anti-deviation device, including
Outer shell 1 and interior sheath body 5, in the outer shell 1, surface is provided with ball slot rolling 6, and the lateral surface of the interior sheath body 5 is provided with second
Ball slot rolling 6, the interior sheath body 5 are placed in outer shell 1, and dispose multiple balls 7 described in two groups between ball slot rolling 6, many
It is fixedly installed by the collar 8 between the individual ball 7, the outer surface top of supply line of the outer shell 1 is also fixed with electrostatic and disappears
Except rod 3, the static elimination bar 3 is connected with the ball slot rolling 6 by circuit, and the static elimination bar 3 is used to eliminate institute
The electrostatic that ball 7 is produced due to friction with the ball slot rolling 6 when rotating is stated, is effectively prevented as electrostatic is to electric fan
The infringement of internal each electric vigour part, is provided with one group of delivery pipe 10 in the interior sheath body 5, connection institute is provided with the interior sheath body 5
The straight defeated pipe 11 and vertical defeated pipe 12 of delivery pipe 10 are stated, the front surface of the interior sheath body 5 is fixedly installed one group of pushing socket 13,
Pushing interval 14, and the pushing interval 14 and straight 11 connect setting of defeated pipe are provided with the pushing socket 13, it is described
Pushing socket 13 and one group of pushing ring 15 of placement in interval 14 being pushed positioned at described, the middle part of the upper surface for pushing ring 15 is solid
Surely one group is arranged through between the screw thread straight-bar 16 for pushing socket 13, and the screw thread straight-bar 16 and the pushing socket 13
It is threaded connection, the screw thread straight-bar 16 is being fixedly installed one group of nut 17 positioned at the outside for pushing socket 13, described
The middle part of interior sheath body 5 is provided with blank interval 9, and the interior sheath body 5 is fixedly installed multiple top pressures at the position for being located between clear area 9
