Position.
The beneficial effects of the utility model are:
This utility model uses the mode of linear bearing and vibration isolation rubber combination to realize centrifugal basket vibration isolation, energy
Enough reduction is transmitted pivoted arm, the impact of working sensor performance to centrifuge pivoted arm owing to vibrator vibrates, and
And simple in construction, structure design cost is relatively low；Structure, while vibration damping, is had certain by vibration isolation rubber
Position-limiting action, its comprehensive effectiveness in vibration suppression is more preferable；Attachment structure between hanger and base plate is not by centrifugal basket
Structure, vibrator mode of vibration and oscillating load limit, and can apply on any barrel structure needing vibration damping.

Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings:
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8 and Fig. 9, this practicality is new
Type includes that base plate 1, the left and right sides of base plate 1 are provided with hanger (label 3 and 4), the left and right of base plate 1
Both sides are provided with groove 11, and the hanger of the left and right sides is connected in the groove 11 of both sides, and hanger is arranged
There is bearing mounting hole (label 32 and 42), in the bearing mounting hole of hanger, be provided with linear bearing 6, straight line
Being cased with bearing pin 2 in bearing 6, be provided with pin-and-hole 12 in the groove 11 of base plate 1, bearing pin 2 is arranged on groove 11
Pin-and-hole 12 in, bearing pin 2 is cased with being positioned at the two panels vibration isolation rubber 7 of groove 11, two panels vibration isolation rubber 7 points
