Specific implementation mode
The utility model is further described below in conjunction with the accompanying drawings：
As shown in Figure 1 and Figure 2, the low pressure of the utility model rotates dust guard, mainly by pedestal 10, rotary body 8 and clip
7 three parts form.Wherein, pedestal 10 is a tube structure, and outer convex edge is radially provided in 10 upper end of pedestal, at 10 middle part of pedestal
Bypass pipe 11 is radially provided on cylinder.Rotary body 8 is an annulus harden structure, and rotary body is axially arranged with through-hole, rotary body at 8 axle center
8 lower faces are fixedly connected with glue core 5 along axis through-hole, and 8 lower face of rotary body is equipped with and 10 upper axial hole rotatory sealing of pedestal
The annular boss of cooperation.Clip 7 is opening clip, and is axially and radially limited rotary body 8 in pedestal 10 by caging bolt 6
On the outer convex edge of upper end.Rotatable engagement is constituted between rotary body 8 and pedestal 10 and clip 7.
Further, the clip 7 is that one end of two arc-shaped clamps passes through limit spiral shell by fixing pivot hinge, the other end
Bolt 6 connects, and clip inner surface band is fluted.
Further, 8 upper and lower plane of the rotary body is respectively equipped with rolling bearing 1 with clip 7 and 10 engaging portion of pedestal,
