The specific embodiment
Refer to shown in Fig. 1 and Fig. 2, shown overall schematic and the top view of rubber spring vibration isolator of the present invention, comprise successively from top to bottom and heighten pad 1, gripper shoe 2, the section of heightening inner core 3, upper padding plate 4, rubber spring 5, lower bolster 6 and positioning bolt 7.
Wherein, this section of heightening inner core 3 comprise annulus in the middle of being positioned at and from annulus is upwardly extending cylinder and from annulus to downward-extension cylinder, the wall thickness of described upper cylinder is with reducing highly gradually, and its inner surface and external surface all have tapering, and the wall thickness of described lower cylinder is with highly remaining unchanged.
Wherein, this gripper shoe 2 is arranged at the top of the upper cylinder of the section of heightening inner core 3, at least one heightens pad 1 and is arranged at the top of this gripper shoe 2, by regulate this at least one heighten the specification of pad 1 and quantity and arrange the height of whole rubber spring vibration isolator, preferably, this at least one heighten pad to have thickness be 1mm, 2mm, 5mm, 10mm, 15mm, 20mm, these 7 kinds of specifications of 25mm.
Preferably, this gripper shoe 2 and to heighten the shape of pad 1 identical, all there is unique appearance design, this gripper shoe 2 and heighten pad 1 for circular and have three shape of ears projections in annulus periphery equi-spaced apart, three projections between two interval 120 are spent, in annulus, week is above provided with three grooves in the position of corresponding each projection, concrete gripper shoe 2 can be participated in Fig. 5 and Fig. 6 with the shape of heightening pad 1, and preferably, be provided with the fixture that correspondence is fixed this gripper shoe 2 and heightened pad 1, corresponding three grooves of this fixture are provided with three circular protrusions, optionally, this fixture can be selected various fixed forms, as bolt screw etc.By such structure design, gripper shoe of the present invention is more balanced with the compressed structure of heightening pad, and effectiveness in vibration suppression is better.
