The first embodiment is as follows:

the embodiment of the utility model provides a damping callus on sole for with pendulum 100 installation fixed on the fixed mounting face (when pendulum 100 direct mount subaerial, then fixed mounting face is ground, when pendulum 100 installs on work platform, then fixed mounting face is work platform's mesa, when pendulum 100 installs in equipment shell, then fixed mounting face is equipment shell's inside wall, etc.), and at the in-process that pendulum 100 carries out work, pendulum 100 produces the vibration, then vibration transmission to the damping callus on sole, the purpose of making an uproar falls in order to realize the damping through the vibration mechanical energy conversion that the vibration callus on sole produced pendulum 100.

As shown in fig. 1, the damping foot pad of the first embodiment of the present invention includes a support tube 10, a first damping ring wall 20 and a connecting body 30, which form a core component of the damping foot pad. Support cylinder 10 have be used for being connected to the fixed mounting face first end 11 and with 11 relative second ends 12 of first end, first damping rampart 20 has first inner ring periphery 21 and centers on first outer loop periphery 22 of first inner ring periphery 21, first outer loop periphery 22 with second end 12 is connected, first damping rampart 20's wall certainly first outer loop periphery 22 extremely first inner ring periphery 21 is towards keeping away from the direction slope of first end 11 sets up, first damping rampart 20 can produce elastic deformation (first damping rampart 20 has elasticity promptly), first damping rampart 20 is the flexible body that can produce elastic deformation, connector 30 connect in on the first inner ring periphery 21, the last annular groove 31 that has the footing that is used for installing pendulum 100 that opens of connector 30, be equipped with limit ring platform 32 on the connector 30, stop ring platform 32 is located annular groove 31 with between the first damping rampart 20, stop ring platform 32 with the interval has between the first damping rampart 20, just stop ring platform 32 be used for with the footing looks butt of pendulum 100, wherein, support the section of thick bamboo 10 first damping rampart 20 and connector 30 is equipped with the perforating hole 1 that axial direction link up, perforating hole 1 be used for pass with the footing of pendulum 100 is fixed extremely the fastener of fixed mounting face.

Use the embodiment of the utility model provides a damping callus on the sole with pendulum 100 installation fix on fixed mounting face, during the assembly, the footing cover of pendulum 100 is in the annular 31 of connector 30 to stop collar platform 32 supports the footing of pendulum 100, then passes perforating hole 1 with the fastener and is connected to fixed mounting face. After the assembly is completed, since the wall surface of the first damping ring wall 20 is inclined from the first outer ring peripheral edge 22 to the first inner ring peripheral edge 21 in the direction away from the first end 11, and the first damping ring wall 20 can be elastically deformed in the axial direction, the first damping ring wall 20 is elastically deformed in the axial direction to sink under the action of the gravity of the vibrating body 100, so that the vibrating body 100 can be fixedly attached to the fixed attachment surface in a balanced manner. In the process that the vibrating body 100 operates to generate vibration energy, the vibration energy is firstly transmitted to the connecting body 30 and then transmitted to the first vibration reduction annular wall 20, and the first vibration reduction annular wall 20 further generates elastic deformation under the action of the vibration energy (at this time, the first vibration reduction annular wall 20 generates complex deformation of multiple degrees of freedom in the axial direction, the circumferential direction and the radial direction under the excitation of the vibration energy), so that the vibration energy is converted into deformation potential energy and heat internal energy of the first vibration reduction annular wall 20, the transmission of the vibration energy to the fixed mounting surface is effectively reduced, the noise generated by the vibration of the fixed mounting surface under the excitation of the vibration energy is reduced, and the effects of noise elimination and noise reduction are realized.

Specifically, the utility model provides a damping callus on sole adopt rubber material integrated into one piece to be holistic flexible member, that is, the damping callus on sole is whole all can take place elastic deformation (damping callus on the sole has elasticity promptly), for example, the spacing ring platform 32 that supports the footing of pendulum 100 also can take place elastic deformation thereupon under the excitation of the vibrational energy that pendulum 100 produced, spacing ring platform 32 also converts the vibrational energy of part into deformation potential energy and hot internal energy promptly to supplementary realization noise elimination falls the purpose of making an uproar.

In the damping foot pad according to the first embodiment, a projection area of the retainer ring 32 in the axial direction is smaller than a projection area of the first damping ring wall 20 in the axial direction. Like this, when first damping rampart 20 sinks along axial direction and warp to the limit, then spacing ring platform 32 supports and connects to on the wall of first damping rampart 20, because spacing ring platform 32 is the flexible component that can elastic deformation with first damping rampart 20, consequently, spacing ring platform 32 can avoid the direct wall that supports first damping rampart 20 of footing of rigid pendulum 100, thereby avoid causing first damping rampart 20 to suffer damage, can guarantee the completeness of first damping rampart 20, and like this, first damping rampart 20 just can resume normal damping ability after the vibration excitation of pendulum 100 cancels or reduces. Moreover, the maximum stroke of the connecting body 30 in the axial direction can be limited by the cooperation between the limit ring platform 32 and the first vibration-damping ring wall 20, that is, the maximum stroke of the connecting body 30 in the axial direction is smaller than the height of the support cylinder 10, so that when the connecting body 30 is vibrated to sink to the limit position under the excitation of the vibration energy of the vibrating body 100, the limit ring platform 32 abuts against the wall surface of the first vibration-damping ring wall 20, so that the connecting body 30 cannot directly abut against the fixed mounting surface, the vibration energy cannot be transmitted to the fixed mounting surface, and the wall surface excites the fixed mounting surface to generate noise by the vibration energy.

Specifically, in order to enhance the mechanical strength of the support cylinder 10, that is, the support rigidity of the support cylinder 10 for the vibration body 100, a boss structure 80 is provided on the support cylinder 10, and the boss structure 80 is used for enhancing the support rigidity of the support cylinder 10. As shown in fig. 1, the boss structure 80 is at least one annular boss 81 circumferentially disposed on the inner sidewall and/or the outer sidewall of the support cylinder 10. The utility model discloses in the damping callus on the sole of embodiment one, the quantity of annular boss 81 is one to this annular boss 81 deviates from the side end face of connector 30 and the terminal surface parallel and level of first end 11, and annular boss 81 deviates from the side end face of connector 30 and the terminal surface butt fixed mounting face simultaneously of first end 11, has increased the area of contact between damping callus on the sole and the fixed mounting face, makes the damping callus on the sole can be more stable install on fixed mounting face.

Furthermore, the fastener inserted into the through hole 1 has a clearance with at least a part of the hole wall of the through hole 1, that is, the fastener is in clearance fit with the through hole 1. In this way, when the oscillating body 100 is operated to generate vibration energy excitation, the fastening element can be subjected to damping displacement in the gap between the fastening element and the hole wall of the through hole 1 during the oscillation displacement of the oscillating body 100 in the circumferential direction and the radial direction, and then the fastening element transmits the vibration energy to the connecting body 30 in the circumferential direction and the radial direction.

Example two:

as shown in fig. 2, it shows the structure of the damping foot pad provided by the second embodiment of the present invention. The vibration-damping foot pad of the second embodiment has the following differences compared to the vibration-damping foot pad of the first embodiment.

In the second embodiment, the damping foot pad further includes a protection bushing 90, the protection bushing 90 is disposed in the through hole 1, and the protection bushing 90 is used for penetrating the fastening member. So, separate through protection bush 90 between fastener and the damping callus on the sole for the screw thread of fastener does not direct contact perforating hole 1's pore wall, like this, when vibrating 100 operation produced vibration energy, avoids the pore wall of fastener rigidity butt perforating hole 1, thereby has protected the damping callus on the sole can not damaged by the screw thread of fastener, can further prolong the life of damping callus on the sole.

When assembled, the outer circumferential wall of the protective bush 90 has a clearance with at least part of the bore wall of the through bore 1, i.e. there is a clearance fit between the protective bush 90 and the through bore 1. In this way, when the oscillating body 100 is excited by vibration energy generated during operation, the fastening element can be displaced in a manner to absorb vibrations in the gap between the protective bush 90 and the hole wall of the through hole 1 during the oscillating displacement of the oscillating body 100 in the circumferential direction as well as in the radial direction, and then the fastening element transmits the vibration energy to the connecting body 30 in the circumferential direction as well as in the radial direction.

Or, when assembling, the circumferential outer wall of the protection bush 90 is in interference fit or transition fit with at least part of the hole wall of the through hole 1, and a gap is formed between the fastener penetrating through the protection bush 90 and the hole wall of the through hole of the protection bush 90, that is, the fastener and the protection bush 90 are in clearance fit. In this way, when the oscillating body 100 is excited by vibrational energy generated during operation, the fastening element can be displaced in a damped manner in the gap between the fastening element and the protective sleeve 90 following the oscillating body 100 during the oscillating displacement in the circumferential direction as well as in the radial direction, before the fastening element transmits the vibrational energy in the circumferential direction as well as in the radial direction to the connecting body 30.

Further alternatively, when assembling, there is a gap between the circumferential outer wall of the protective bush 90 and at least a part of the hole wall of the through hole 1, and there is a gap between the fastener inserted into the protective bush 90 and the hole wall of the through hole of the protective bush 90, that is: the protective bushing 90 is in a clearance fit with the through hole 1, and the fastener is in a clearance fit with the protective bushing 90. In this way, when vibration energy is excited during operation of vibrator 100, the fastening element can be displaced in a damped manner in the gap between the fastening element and protective bush 90 and in the gap between protective bush 90 and the wall of through-hole 1 during the vibration displacement of vibrator 100 in the circumferential direction and in the radial direction, before the fastening element transmits the vibration energy to connecting body 30 in the circumferential direction and in the radial direction.

Specifically, the protective bush 90 may be a flexible member molded by using a rubber material, or may be a rigid member molded by using a rigid material. Also, the protective sleeve 90 is preferably a sleeve whose circumferential outer wall is a cylindrical surface.

Compared with the vibration-damping foot pad of the first embodiment, the vibration-damping foot pad of the second embodiment has the same structure except for the above structure, and thus is not described herein again.

Example three:

as shown in fig. 3, it shows the structure of the vibration-damping foot pad provided by the third embodiment of the present invention. The vibration-damping foot pad of the third embodiment has the following differences compared to the vibration-damping foot pad of the second embodiment.

In the vibration-damping foot pad of the third embodiment, a plurality of first adjusting holes 14 distributed circumferentially are formed in the support cylinder 10, and each of the first adjusting holes 14 extends in the axial direction. The first regulation holes 14 are evenly distributed in the circumferential direction. The first adjusting hole 14 is formed in the supporting cylinder 10 to adjust the supporting rigidity of the supporting cylinder 10, and the overall weight of the adjustable damping foot pad can be reduced.

Furthermore, second adjusting holes 814 are circumferentially distributed on the annular boss 81, and each second adjusting hole 814 extends in the axial direction. The respective second regulation holes 814 are uniformly distributed in the circumferential direction. The rigidity of the annular boss 81 is adjusted by forming the second adjusting hole 814 on the annular boss 81, so that the rigidity of the annular boss 81 can be more matched with the supporting rigidity of the supporting cylinder 10, and the second adjusting hole 814 and the first adjusting hole 14 together reduce the overall weight of the adjusting damping foot pad.

As shown in FIG. 3, at least one annular adjustment groove 13 is formed on the inner wall and/or the outer wall of the support cylinder 10. In the third embodiment, the number of the annular adjusting grooves 13 is one, and the annular adjusting grooves are formed in the inner side wall of the support cylinder 10. The annular adjusting groove 13 is formed in the supporting cylinder 10, so that the supporting rigidity of the supporting cylinder 10 is further adjusted, and meanwhile, the overall weight of the damping foot pad can be further reduced.

As shown in FIG. 3, the cross-sectional profile of the annular adjustment groove 13 has a diameter d ₁ The diameter of the through hole 1 corresponding to the supporting cylinder 10 is D ₁ The diameter of the outer circle profile of the cross section of the supporting cylinder 10 is D ₂ Then 0 < d ₁ ＜D ₂ -D ₁ Therefore, on the basis that the supporting cylinder 10 is guaranteed to have enough supporting rigidity, the whole weight of the damping foot pad can be further reduced, and the material consumption of the damping foot pad is saved.

Compared with the damping foot pad of the second embodiment, the damping foot pad of the third embodiment has the same structure except for the difference of the above structures, and thus the description thereof is omitted.

Example four:

as shown in fig. 4, it shows the structure of the damping foot pad provided by the fourth embodiment of the present invention. The vibration-damping foot pad of the fourth embodiment has the following differences compared to the vibration-damping foot pad of the second embodiment.

That is, the sectional profile shape of the annular boss 81 of the fourth embodiment is a "Z" shape (as shown in fig. 4), so that even in the case where the overall weight of the vibration-damping foot pad of the second embodiment is the same as or slightly smaller than that of the vibration-damping foot pad of the second embodiment (the overall weight of the vibration-damping foot pad of the fourth embodiment is slightly smaller, mainly in further reducing the weight of the annular boss 81), the rigidity of the annular boss 81 itself can be further improved, thereby assisting in adjusting the support rigidity of the support tube 10.

Compared with the damping foot pad of the second embodiment, the damping foot pad of the fourth embodiment has the same structure except for the above structure, and thus is not described herein again.

In the vibration reduction foot pad of the fourth embodiment, different from the vibration reduction foot pad of the third embodiment, the first ring segment 811 of the annular boss 81 is provided with second adjustment holes 814 distributed circumferentially, and each of the second adjustment holes 814 extends in the axial direction. In addition, a plurality of second adjusting bores 814 distributed in the circumferential direction may also be provided in the second ring segment 812 and/or the third ring segment 813.

Compared with the damping foot pad of the third embodiment, the damping foot pad of the fourth embodiment has the same structure except for the difference, and thus the description is omitted.

Example five:

as shown in fig. 5, it shows the structure of the vibration-damping foot pad provided by the fifth embodiment of the present invention. The vibration-damping foot pad of the fifth embodiment has the following differences compared to the vibration-damping foot pad of the first embodiment.

In the fifth vibration reduction foot pad of embodiment, the boss structure 80 is a plurality of strip-shaped bosses 82 arranged on the outer side wall of the support cylinder 10, and each strip-shaped boss 82 extends along the axial direction. Moreover, the plurality of strip-shaped bosses 82 are uniformly distributed on the outer wall of the support cylinder 10 at intervals in a circumferential direction, and the support rigidity of the support cylinder 10 is enhanced by arranging the plurality of strip-shaped bosses 82 on the support cylinder 10. Each strip boss 82 deviates from the end face of the connecting body 30 and is flush with the end face of the first end 11 of the supporting cylinder 10, so that the contact area between the damping foot pad and the fixing and mounting surface is increased, and the damping foot pad can be more stably mounted on the fixing and mounting surface.

Compared with the damping foot pad of the first embodiment, the damping foot pad of the fifth embodiment has the same structure except for the difference, and thus the description thereof is omitted.

Example six:

as shown in fig. 6, it shows the structure of the vibration-damping foot pad provided by the sixth embodiment of the present invention. The vibration-damping foot pad of example six has the following differences compared to the vibration-damping foot pad of example five.

In the vibration reduction foot pad of the sixth embodiment, the boss structure 80 is a plurality of strip-shaped bosses 82 disposed on the inner side wall of the support cylinder 10, and each strip-shaped boss 82 extends in the axial direction. Moreover, the plurality of strip-shaped bosses 82 are uniformly distributed on the inner wall of the support cylinder 10 at intervals in a circumferential direction, and the support rigidity of the support cylinder 10 is enhanced by arranging the plurality of strip-shaped bosses 82 on the support cylinder 10. The end face of each strip-shaped boss 82 departing from the connecting body 30 is flush with the end face of the first end 11 of the support cylinder 10, so that the contact area between the damping foot pad and the fixed mounting surface is increased, and the damping foot pad can be more stably mounted on the fixed mounting surface.

Compared with the damping foot pad of the fifth embodiment, the damping foot pad of the sixth embodiment has the same structure except for the difference, and thus the description thereof is omitted.

Example seven:

as shown in fig. 7, it shows the structure of the vibration-damping foot pad provided by the seventh embodiment of the present invention. The vibration-damping foot pad of example seven has the following differences compared to the vibration-damping foot pad of example six.

In the vibration reduction foot pad according to the seventh embodiment, the plurality of strip-shaped bosses 82 are divided into a plurality of groups, each strip-shaped boss 82 in each group is uniformly circumferentially distributed at intervals for a circle, and each strip-shaped boss 82 in each adjacent two groups coaxially extends in the axial direction in a one-to-one correspondence manner and is arranged at intervals, so that the support rigidity of the support cylinder 10 is enhanced. Wherein, in a set of strip boss 82 that deviates from connector 30, the tip terminal surface that each strip boss 82 deviates from connector 30 all with the first end 11 terminal surface parallel and level of a support section of thick bamboo 10, increased the area of contact between damping callus on the sole and the fixed mounting face for the damping callus on the sole can be more stable install on the fixed mounting face.

Compared with the vibration-damping foot pad of the sixth embodiment, the vibration-damping foot pad of the seventh embodiment has the same structure except for the difference, and thus the details are not repeated herein.

Example eight:

as shown in fig. 8, it shows the structure of the vibration damping foot pad provided by the eighth embodiment of the present invention. The vibration-damping foot pad of example eight has the following differences compared to the vibration-damping foot pad of example one.

In the shock absorbing foot pad according to the eighth embodiment, the shock absorbing foot pad further includes at least one shock absorbing annular wall 40, the shock absorbing annular wall 40 has a second inner annular periphery 41 and a second outer annular periphery 42 surrounding the second inner annular periphery 41, the second outer annular periphery 42 is connected to the first inner annular periphery 21 (the second outer annular periphery 42 may be directly connected to the first inner annular periphery 21 or indirectly connected to the first inner annular periphery 21), the connecting body 30 is directly connected to the second inner annular periphery 41, and the shock absorbing annular wall 40 is inclined from the second outer annular periphery 42 to the second inner annular periphery 41 in a direction away from the first end 11. The damper sub-ring wall 40 is elastically deformable, that is, the damper ring wall 40 has elasticity.

After the vibrating body 100 is mounted on the vibration-damping pad, the first vibration-damping annular wall 20 and the vibration-damping annular wall 40 are elastically deformed in the axial direction and sink under the action of the gravity of the vibrating body 100, so that the vibrating body 100 can be fixedly connected to the fixed mounting surface in a balanced manner.

In the process that the vibration body 100 operates to generate vibration energy, the vibration energy is firstly transmitted to the connecting body 30 and then transmitted to the vibration reduction sub-ring wall 40, at this time, the vibration reduction sub-ring wall 40 further generates elastic deformation under the action of the vibration energy (at this time, the vibration reduction sub-ring wall 40 generates complex deformation with multiple degrees of freedom in the axial direction, the circumferential direction and the radial direction under the excitation of the vibration energy), so that the vibration energy (all the vibration energy or most of the vibration energy) is converted into deformation potential energy and thermal internal energy of the vibration reduction sub-ring wall 40, the noise generated by the vibration of the fixed mounting surface under the excitation of the vibration energy is reduced, and the effects of noise elimination and reduction are realized.

When the vibration reduction sub-ring wall 40 vibrates and sinks to the stroke limit along the axial direction, the vibration energy generated by the vibration body 100 is continuously transmitted to the first vibration reduction ring wall 20, and the first vibration reduction ring wall 20 further generates elastic deformation under the action of the vibration energy (at this time, the first vibration reduction ring wall 20 generates complex deformation of multiple degrees of freedom superposition in the axial direction, the circumferential direction and the radial direction under the excitation of the vibration energy), so that the vibration energy is converted into deformation potential energy and thermal internal energy of the first vibration reduction ring wall 20, in this way, the vibration energy is effectively reduced and transmitted to the fixed installation surface, the noise generated by the vibration of the fixed installation surface under the excitation of the vibration energy is reduced, and the effects of noise elimination and noise reduction are realized.

Therefore, the vibration reduction annular wall 40 is matched with the first vibration reduction annular wall 20, so that the vibration energy generated by the vibration body 100 can be converted into deformation potential energy and thermal internal energy, and the noise generated by the vibration of the fixed mounting surface due to the excitation of the vibration energy is reduced.

When the number of the vibration reduction ring walls 40 is one, the vibration reduction foot pad further comprises one transition support cylinder 50, the number of the transition support cylinder 50 is one, one end of the transition support cylinder 50 is connected to the first inner ring periphery 21, and the other end of the transition support cylinder 50 is connected to the second outer ring periphery 42. Moreover, the axial direction projection area of the limit ring table 32 is smaller than that of the ring wall 40, so when the ring wall 40 sinks to deform to the limit along the axial direction, the limit ring table 32 abuts against the wall surface of the ring wall 40, and because the limit ring table 32 and the ring wall 40 are both flexible parts capable of elastic deformation, the limit ring table 32 can prevent the bottom feet of the rigid vibrator 100 from directly abutting against the wall surface of the ring wall 40, thereby preventing the ring wall 40 from being damaged, and ensuring the integrity of the ring wall 40.

Or, when the number of the vibration reducing ring walls 40 is multiple, the vibration reducing foot pad further includes a transition support cylinder 50, the number of the transition support cylinders 50 is multiple, and multiple transition support cylinders 50 correspond to multiple vibration reducing ring walls 40 one by one, the first vibration reducing ring wall 20 and the vibration reducing ring wall 40 adjacent thereto are connected by one transition support cylinder 50 (i.e. the first inner ring circumferential edge 21 is connected with one end of the transition support cylinder 50, the second outer ring circumferential edge 42 of the vibration reducing sub-ring wall 40 adjacent to the first vibration reducing ring wall 20 is connected with the other end of the transition support cylinder 50), and two adjacent vibration reducing ring walls 40 are connected by one transition support cylinder 50 (the second inner ring circumferential edge 41 of one vibration reducing ring wall 40 close to the first vibration reducing ring wall 20 is connected with one end of the transition support cylinder 50, and the second outer ring circumferential edge 42 of one vibration reducing ring wall 40 far from the first vibration reducing ring wall 20 is connected with the other end of the transition support cylinder 50 ) In the direction from the first vibration reduction annular wall 20 to the vibration reduction annular wall 40, the projection area of each vibration reduction annular wall 40 in the axial direction is reduced in sequence. Moreover, the axial direction projection area of the limit ring stand 32 is smaller than the axial direction projection area of the ring wall 40 connected with the connecting body 30, so that when the ring wall 40 connected with the connecting body 30 sinks and deforms to the maximum along the axial direction, the limit ring stand 32 abuts against the wall surface of the ring wall 40 connected with the connecting body 30, and since the limit ring stand 32 and the ring wall 40 are both flexible components capable of elastic deformation, the limit ring stand 32 can prevent the bottom foot of the rigid vibrating body 100 from directly abutting against the wall surface of the ring wall 40 connected with the connecting body 30, thereby preventing the ring wall 40 from being damaged, and ensuring the integrity of the ring wall 40.

Compared with the damping foot pad of the first embodiment, the damping foot pad of the eighth embodiment has the same structure except for the difference, and thus the description thereof is omitted.

Example nine:

as shown in fig. 9, it shows the structure of the vibration-damping foot pad provided by the ninth embodiment of the present invention. The vibration-damping foot pad of example nine has the following differences compared to the vibration-damping foot pad of example one.

In the vibration-damping foot pad of the ninth embodiment, the vibration-damping foot pad further includes a second vibration-damping ring wall 60 and a bottom supporting platform 71, the second vibration-damping ring wall 60 has an inner edge 61 and an outer edge 62 surrounding the inner edge 61, the outer edge 62 is connected to the first end 11, the inner edge 61 is connected to one end of the bottom supporting platform 71 (the inner edge 61 and the bottom supporting platform 71 may be directly connected or the inner edge 61 is indirectly connected to the bottom supporting platform 71), the other end of the bottom supporting platform 71 is used for supporting on a fixed mounting surface, a wall surface of the second vibration-damping ring wall 60 inclines in a direction opposite to a wall surface of the first vibration-damping ring wall 20, and the second vibration-damping ring wall 60 can be elastically deformed (i.e., the second vibration-damping ring wall 60 has elasticity), wherein the bottom supporting platform 71 is provided with a through hole opposite to the through hole 1.

In the process that the vibrating body 100 operates to generate vibration energy, the vibration energy is firstly transmitted to the connecting body 30 and then transmitted to the first vibration reduction annular wall 20, and the first vibration reduction annular wall 20 further generates elastic deformation under the action of the vibration energy (at this time, the first vibration reduction annular wall 20 generates complex deformation with multiple degrees of freedom in the axial direction, the circumferential direction and the radial direction under the excitation of the vibration energy), so that the vibration energy is converted into deformation potential energy and thermal internal energy of the first vibration reduction annular wall 20, and the noise generated by the vibration of the fixed mounting surface under the excitation of the vibration energy is reduced. When the first vibration-damping annular wall 20 vibrates along the axial direction and sinks to the stroke limit, the vibration energy generated by the vibrating body 100 is continuously transmitted to the second vibration-damping annular wall 60, and the second vibration-damping annular wall 60 further generates elastic deformation under the action of the vibration energy (at this time, the second vibration-damping annular wall 60 generates complex deformation of multiple degrees of freedom in the axial direction, the circumferential direction and the radial direction under the excitation of the vibration energy), so that the vibration energy is further converted into deformation potential energy and thermal internal energy of the second vibration-damping annular wall 60, the vibration energy is effectively transmitted to the fixed mounting surface, the noise generated by the vibration of the fixed mounting surface under the excitation of the vibration energy is reduced, and the effects of noise elimination and noise reduction are realized.

The axial direction projected area of the bottom mount 71 is smaller than the axial direction projected area of the second vibration damping annular wall 60. Thus, when the second damper ring wall 60 is vibrated in the axial direction and sinks to the stroke limit, the wall surface of the second damper ring wall 60 is in contact with the bottom mount base 71, and the second damper ring wall 60 is elastically deformed, so that the wall surface of the second damper ring wall 60 is still at a displacement distance of the height of the bottom mount base 71 after being in contact with the bottom mount base 71 to damp vibration, thereby reducing noise generated when the first end 11 directly collides with the fixed mounting surface.

Alternatively, the axial direction projected area of the bottom mount 71 is larger than the axial direction projected area of the second damper ring wall 60. Thus, when the second vibration damping annular wall 60 is vibrated and sunk to the stroke limit in the axial direction, the first end 11 is in contact with the bottom support base 71, and the noise generated when the first end 11 directly collides with the fixed mounting surface is reduced.

The damping callus on sole still includes bottom connecting cylinder 72, the one end of bottom connecting cylinder 72 with inner edge 61 is connected, the other end of bottom connecting cylinder 72 with bottom supporting bench 71 is connected, just the axial direction projection area of bottom connecting cylinder 72 is less than the axial direction projection area of bottom supporting bench 71.

Compared with the vibration-damping foot pad of the first embodiment, the vibration-damping foot pad of the ninth embodiment has the same structure except for the difference, and thus the details are not repeated herein.

After the assembly is completed, the vibration energy is converted into deformation potential energy and thermal internal energy of the first vibration reduction annular wall 20, the vibration reduction annular wall 40, the second vibration reduction annular wall 60 and the like, so that the vibration energy is effectively reduced from being transmitted to the shell, the noise generated by the shell when the shell is excited by the vibration energy and vibrates is reduced, and the effects of noise elimination and noise reduction are realized.
