Specific embodiment
Presently filed embodiment is described in detail below in conjunction with accompanying drawings and embodiments.
As shown in Figure 1, the utility model provides outside a kind of agitating shaft sealing device, including axle sleeve 1, the axle sleeve 1
The gripping sleeve 3 of side, the gripping sleeve 3 are in two halves formula, and sealing ring 2, the gripping sleeve 3 are equipped between the axle sleeve 1 and agitating shaft
Top for symmetrical two semi-ring bodies, 3 outside of gripping sleeve is equipped with upper thread segment 4, screws lock at the upper thread segment 4
Determine nut 6；It is equipped with lower thread segment 5 in the lower part in 3 outside of gripping sleeve, screws tightening nut 7, institute at the lower thread segment 5
Stating 3 upper and lower side of gripping sleeve respectively has nut to screw the clamping force between fixed enhancing gripping sleeve 3 and axle sleeve 1, agitating shaft, so that sealing
Circle 2 is clamped between agitating shaft and axle sleeve 1 well, enhances sealing effect, wherein the tightening nut 7 of 3 bottom of gripping sleeve with
The gripping sleeve 3 is flexibly connected, the sealing being convenient for changing inside the axle sleeve 1 and the axle sleeve 1 of 3 inside of gripping sleeve
Circle 2.
Further, the top of the upper thread segment 4 to 3 top surface of gripping sleeve is equipped with a distance, with lock nut 6
Shape matches, and enhances the latching force of lock nut 6, also enhances the leakproofness of agitating shaft upper end.
Further, 6 upper inside wall of lock nut is smooth, fits with the outer wall of the gripping sleeve 3, its underpart
Inner wall is equipped with the screw thread matched with the thread segment.
Further, 5 bottom end of lower thread segment is flushed with 3 bottom end of gripping sleeve.
Further, it is equipped with the sealing ring 2 in the top and bottom of agitating shaft, enhances it from upper and lower ends respectively
Sealing effect.
One embodiment of the utility model is described in detail above, but the content is only the utility model
Preferred embodiment should not be considered as limiting the scope of the present invention.It is all to be made according to application scope of the utility model
All the changes and improvements etc., should still belong within the patent covering scope of the utility model.
