The end of two cylinders is oppositely arranged and distinguishes the two ends of sheathed spring 5.This structure, under external force, pedestal is in silica gel ring
Guiding under, along set cavity inner wall decline, while extrusion spring, spring transmits the force to lower silicagel pad, lower silicagel pad is passed again
Pass backing plate；In power transmittance process, spring, upper silicagel pad, lower silicagel pad play good damping effect.
Silica gel ring 7 is column structure, and outer peripheral face is resisted against the cavity madial wall of set 6.The width of the height of cylinder, i.e. outer peripheral face
Degree, adds the contact area of silica gel ring 7 and set 6, adds silica gel ring and slides the effective guiding length provided by pedestal, makes
Pedestal slip is more steady, while also strengthening support degree, can directly be contacted between pedestal and set, it is to avoid vibration is transmitted from pedestal 9
To set 6, so as to obtain more preferable effectiveness in vibration suppression.
Stretch out set 6 the end of pedestal 9 one section of damping trough 11 provided circumferentially about, damping trough 11 circumferentially face ring around cyclization
Shape；During in off working state, the width of damping trough 11 is more than the distance between the upper cylinder of silicagel pad 8 and lower cylinder of silicagel pad 4, subtracts
The lower lip for shaking groove 11 is in the outside of 6 blind end outer faces of set.
Upper silicagel pad 8, lower silicagel pad 4 and cylinder thereon are hollow structure.Hollow structure increase elasticity, when upper silica gel
When pad, the cylinder of lower silicagel pad lean, increase the deformation space of cylinder, improve the elasticity of cylinder, strengthen effectiveness in vibration suppression.
The bottom of hollow structure sets pin 1 to constitute fixed structure, and pin 1 is in upper silicagel pad 8, the length of lower silicagel pad 4
The length of cylinder where degree is not more than half.Pin 1 can be fixed on electroplax and pedestal 9 by screw.
Plate pad 3 is slab construction, and lower surface is equipped with silica gel pad 2.In use, when backing plate 3 connects with external stability plane
Connect when being for example threadedly coupled, silica gel pad 2 plays damping effect between backing plate and fixed pan, further improve overall subtracts
Shake effect.
Plate pad 3, set 6, pedestal 9 are non-magnetic material, such as aluminium alloy；Silica gel pad 2, lower silicagel pad 4, silica gel ring 7, on
Silicagel pad 8, silica gel lid 10 are non-magnetic material, are made for example with silica gel.Plate pad, set, pedestal are aluminum alloy material, are constituted
Enclosed construction with demagnetizing action.
Silica gel lid 10 is provided with the end of pedestal 9 for stretching out set 6；Annular groove, annular groove close end are set on the end periphery of pedestal 9
The side wall of the side in face is inclined-plane, annular groove A/F is more than slot bottom width；The main body of silica gel lid 10 is plate body, and periphery is to bottom
Upset extends into annular wall, and annular wall openend forms crozier to turning inside out extension again, and crozier madial wall is and pedestal
On annular groove adaptation inclined-plane；Crozier is buckled into annular groove.
Embodiment 2：As shown in Figure 2, upper silicagel pad 8, the cylinder of lower silicagel pad 4 are provided with cylinder 12；The hole portion of cylinder 12
Corresponding cylinder periphery is placed on, root is outwards turned into flanging, and flanging is resisted against the base portion of silicagel pad 8 or lower silicagel pad 4；Post
Body end portion is in frustum, and frustum root is in the port of cylinder 12 or flushed with the port of cylinder 12.Strengthen cylinder root intensity, improve
Enabling capabilities, it is to avoid overload global failure, top Local Contraction deformation causes after permanent deformation, and lower half can carry out appropriateness automatically
Compensation.
The openend of two cylinders 12, the tapered mouth of indent, the tapered boss of another evagination, the conical opening and the cone
Shape boss against when, constitute be connected.When cylindrical end portions failure, cylinder further compresses, and makes the openend phase of two cylinders 12
Mutually close to until completely attaching to, now, the cooperation of conical opening and the cone boss makes two cylinders 12 form axial connection, and make
Two cylinders keep coaxial state, and the external force from pedestal is delivered on backing plate by base portion, improve effective way of power transmission
Footpath, it is to avoid the relative skew of two cylinders, deflection, so as to avoid damaging cylinder, the cylinder in cylinder, especially avoids damage to cylinder root
The base portion in portion.Therefore, even if the base portion of spring failure, cylinder failure, but upper silicagel pad 8 and lower silicagel pad 4 is in pedestal and backing plate
Between formed support, still can play damping effect, it is to avoid overall damping effect is entirely ineffective.
That is, the area of pedestal is big, compared to cylinder, failure is less susceptible to.When cylinder fails, carried out by cylinder
Power is transmitted, and the base portion of upper silicagel pad and lower silicagel pad still provides three protective effects.
Remaining be the same as Example 1.
In summary, the invention has the advantages that：1）, using silica gel lid, silicagel pad, silica gel pad, wear-resisting, resistance to height
Warm, pressure-resistant, service life is long, is 10 times of General Purpose Rubber pad.2）, device central shaft（That is pedestal）Positioned using silicagel pad,
When spring failure, silicagel pad（Including upper silicagel pad 8, lower silicagel pad 4）Cylinder lean, formed second protection effect.3）、
Silica gel pad, lower silicagel pad, silica gel ring, upper silicagel pad, silica gel lid use silica gel material, reduce noise, reach that noise elimination is acted on.
4）, middle cushioning effect is played using rigidity spring.5）, in product, superstructure all using aluminum alloy drawing material, is played
Demagnetizing action.6）, in silicagel pad（Including upper silicagel pad 8, lower silicagel pad 4）Cylinder on be arranged cylinder.When spring, silicagel pad
When cylinder fails, transmitted by the power of cylinder, the base portion of silicagel pad can independently form three protective effects.
Technical scheme is applicable not only to the vibration damping of transformer, is equally applicable to similar use environment.Example
Such as water pump, blower fan, handpiece Water Chilling Units, the new blower fan of console mode, combined type air conditioner, floor air conditioner, roof type air-conditioner, centrifugation wind
Machine etc..
