It is connect with lower rubber separator 32, the other end is connect with 2 lower end of vibration damping portion.
2 upper end of vibration damping portion is fixedly connected with upper junction plate 13, and lower end is fixedly connected with lower connecting plate 33, and vibration damping portion 2 includes
Spring 21 and rubber column 22.Spring 21 is at least provided with two and is symmetrically distributed in, and upper end and the upper junction plate 13 of spring 21 are fixed,
Lower end is fixed with lower connecting plate 33, and spring 21 can reduce the vibration from upper mounting portion 1 and lower mounting portion 3.
As shown in figure 4, rubber column 22 is correspondingly arranged at the hollow position of spring 21, sectional area is less than the hollow of spring 21
The upper end of area, rubber column 22 is fixedly connected with upper junction plate 13, and the lower end of rubber column 22 is fixedly connected with lower connecting plate 33, rubber
22 upper/lower terminal of rubber column gel column is equipped with protrusion, and correspondence is inserted into the through-hole of upper junction plate 13 and lower connecting plate 33 protrusion respectively.
Rubber column 22 can absorb vibration of the buffering from upper mounting portion 1 and lower mounting portion 3.
The vibration attenuation mechanism of spring 21 is：Spring 21 can extend the time of force effect, i.e., the lower object of same momentum variation by
Power become smaller, that is, haved the function that vibration damping.21 vibration damping of spring has the following advantages：1) static deflection is big, intrinsic frequency
It is low, low frequency vibration isolation performance is good；2) erosions such as oil, water are resistant to, temperature change does not influence performance；3) will not aging, do not occur compacted
Become.The shortcomings that 21 vibration damping of spring is：1) itself damping very little, in resonance, transmission ratio is very big；2) steel wire can transmit when high frequency
Vibration；3) oscillating motion is easy tod produce.
Rubber in rubber column 22 has good high resiliency and high viscosity, the two features are due to the curling in rubber
Caused by the structure of molecule, possess interaction between the rubber molecule in rubber, exactly because this makes it have stickiness
The characteristics of, just because of its two features, it is allowed to have good vibration damping, cushioning effect, in rubber, fissipation factor is got over
Beat more, the damping phenomena of rubber is just more significantly, also more apparent to the damping effect of object.Rubber damping, at right angle
Three directions of coordinate can have wider choice with the rigidity on gyratory directions, all have the effect for absorbing buffering vibration.But
Rubber is easy to aging, and high temperature resistant, resistance to low temperature are relatively poor, and oil resistance is poor, easy to aging in air, especially in daylight
When its distorted movement is excessive aging can also occur for meeting accelerated ageing under direct projection.
In the present embodiment, vibration damping portion 2 using spring 21 and rubber column 22 cooperatively there is damping effect, the excellent of the two to lack
Point is complementary.Spring 21 easily resonates, and vibration transmission is relatively large, simultaneously because vibration is transmitted, is also easy to produce oscillating motion, makes
Absorption of vibrations can be buffered with rubber column 22, the vibration for being transmitted to spring 21 is made to greatly reduce, and rubber column 22 is easy to aging, uses
Service life is shorter, while using spring 21, can bear the vibration damping of rubber column 22 and mitigate, improve the service life of rubber column 22.It carries
The effectiveness in vibration suppression and service life in high entire vibration damping portion 2, have been correspondingly improved the effectiveness in vibration suppression and service life of floor damper,
Damping effect range can also be expanded..
When in use, upper mounting portion 1 is fixedly connected with floor, lower mounting portion 3 is fixedly connected with floor tile.Acoustical vibration
It can be transmitted by floor, can also be transmitted by ground, can also transmitted by the cavity between floor and floor tile.Sound from floor shakes
It is dynamic to pass through upper backup pad 11, rubber separator 12 is reached, absorbing buffering by upper rubber separator 12 falls a part, then continues to reach
Upper junction plate 13, then arrive vibration damping portion 2, by the double damping of spring 21 and rubber column 22, the energy of most acoustical vibration
It reduces, then remaining acoustical vibration continues to reach lower connecting plate 33, arrives lower rubber separator 32, remaining acoustical vibration is by upper rubber
Glue partition board 12 absorbs buffering, at this point, the energy of acoustical vibration is absorbed by weakening layer by layer, finally remains little, when passing to lower branch
When fagging 31, influence of the acoustical vibration to people has dropped down to minimum, and significant effect.Equally, come from ground or cavity
Influence is finally preferably minimized by acoustical vibration by weakening layer by layer.
The foregoing is merely the better embodiment of the utility model, the utility model is not limited to above-mentioned embodiment party
Formula, there may be the changes of partial structurtes in implementation process, if various changes or modifications to the utility model do not depart from
The spirit and scope of the utility model, and belong within the scope of the claims and equivalents of the utility model, then this practicality
It is novel to be also intended to include these modification and variations.
