Embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the utility model in detail.
As shown in Figures 1 to 4, a kind of Industrial fan with shock absorption fan blade, at least one shock absorption fan blade 2 comprising base portion 1 and arrange around base portion 1 outer circumferential face, described base portion 1 surface is circumferentially provided with the fan-shaped mounting groove 11 equal with shock absorption fan blade 2 number, and described fan-shaped mounting groove 11 is positioned at triangle place and is provided with fixing threaded hole 12; Described shock absorption fan blade 2 comprises fan-shaped fixed base 21 and flabellum 23, described fan-shaped fixed base 21 matches with fan-shaped mounting groove 11, correspondingly be positioned at triangle place and be provided with fixed via 25, be positioned at middle part and be provided with supporting sleeve 22, described supporting sleeve 22 is connected with one end of shock structure 27 by damping spring 26, the other end of described shock structure 27 is connected with the end of flabellum 23 away from base portion 1 by decoupling rod 28.
Further, described base portion 1 surface is circumferentially evenly provided with three fan-shaped mounting grooves 11, is correspondingly connected with three shock absorption fan blade 2.
Further, the radian of described fan-shaped mounting groove 11 and fan-shaped fixed base 21 is 60 ° ~ 120 °.
Further, described fan-shaped fixed base 21, supporting sleeve 22 and flabellum 23 are integrated.
Further, the end of described flabellum 23 is provided with fixed pin holes 24, and correspondingly the end of described decoupling rod 28 is connected with fixed pin shaft 29.
The working principle of the present embodiment is:
