Compared with prior art, the present invention has the following advantages:
1, the dynamic core of the present invention and inner hole inner wall are isolated, therefore move core vacantly inside inner hole, upper elastic body and lower elasticity
The left and right sides of body is mutually separated with inner hole left and right sidewall respectively, only by upper elastic body and lower elastic body in vertical direction from upper and lower
Dynamic core is fixed in two sides, and upper and lower two elastomers and dynamic core form the rope-shaped structure that a upper and lower ends are fixed, centre is hanging,
It is big along rope directional stiffness, perpendicular to rope directional stiffness then very little.In use, rope structure is arranged along the vertical direction, it will be outer
Portion's vibrating body is connected on dynamic core, since vertical direction rigidity is big, bears that the deformation of big weight is small, and multiple dampers are applied in combination can
The mechanical oscillation body of firm suspended fixing heavy type.The mechanical oscillation body in vertical direction by resilient material, in vertical direction
Also there is damping capacity；And in the horizontal direction, since rigidity is low, effective damping frequency can accomplish very low lower frequency limit, can
To carry out the low frequency vibration damping of horizontal direction, solve load-bearing capacity it is big when, the high problem of vibration damping lower frequency limit.
2, after the good mechanical oscillation body of suspended fixing of the present invention, under the effect of gravity, the upper elastic body is in tensional state,
The lower elastic body is in compressive state, therefore, can be avoided that upper elastic body or lower elastic body occur Nian Jie with bracket or dynamic core
When the extreme case that emaciated face is fallen, being suspended structure will not slump.
3, mutually separated due to the dynamic core with inner hole inner wall, the left and right sides of the upper elastic body and lower elastic body respectively with
Inner hole left and right sidewall mutually separates, then moves between core and inner hole inner wall, between upper elastic body and lower elastic body and inner hole left and right sidewall
There is certain gap, the dynamic core only passes through upper elastic body and lower elastic body is connect with bracket, and the dynamic core is in inner hole
It can all around be translatable or be rotated along vertical axis, enable dynamic core that fraction of movement and torsion occurs, have in mounting hole few
There is fault-tolerant ability in the case where amount dislocation.
[Detailed description of the invention]
Specific embodiments of the present invention will be described in further detail with reference to the accompanying drawing, in which:
Fig. 1 is main view of the invention；
Fig. 2 is in Fig. 1 along the cross-sectional view in the direction A-A；
Fig. 3 is in Fig. 1 along the cross-sectional view in the direction B-B.
[specific embodiment]
The invention will be further described below in conjunction with the accompanying drawings:
A kind of damper as shown in Figure 1 to Figure 3, including bracket 1, the bracket 1 are equipped with the inner hole 2 through front and back,
The dynamic core 3 for connecting external vibration body is equipped in the inner hole 2, the dynamic core 3 is mutually separated with 2 inner wall of inner hole, the dynamic core 3
It is located at vertical direction between bracket 1 equipped with dynamic core 3 is fixed on upper elastic body 4 and lower elastic body 5 on bracket 1, preferably
Ground, the upper elastic body 4 and lower elastic body 5 are rubber, and the upper elastic body 4 and lower elastic body 5 can also be elastoplastic, bullet
Spring or elastic sheet metal etc., the upper elastic body 4 connect dynamic 2 upper wall of 3 upper end of core and inner hole, and the connection of lower elastic body 5 is dynamic
The left and right sides of 2 lower wall of 3 lower end of core and inner hole, the upper elastic body 4 and lower elastic body 5 is divided with 2 left and right sidewall phase of inner hole respectively
From.The dynamic core 3 is isolated with 2 inner wall of inner hole, therefore moves core 3 vacantly inside inner hole 2, only by upper elastic body 4 and lower bullet
Property body 5 it is from upper and lower two sides that dynamic core 3 is fixed in vertical direction, it is solid that upper and lower two elastomers and dynamic core 3 form a upper and lower ends
Fixed, intermediate hanging rope-shaped structure, it is big along rope directional stiffness, perpendicular to rope directional stiffness then very little.In use, rope
Structure is arranged along the vertical direction, and external vibration body is connected on dynamic core 3, since vertical direction rigidity is big, bears big weight and becomes
Shape is small, and the mechanical oscillation body that can consolidate suspended fixing heavy type is applied in combination in multiple dampers.The mechanical oscillation body is in vertical direction
By resilient material, also there is damping capacity in vertical direction；And in the horizontal direction, since rigidity is low, effective damping frequency
Can accomplish very low lower frequency limit, the low frequency vibration damping of horizontal direction can be carried out, solve load-bearing capacity it is big when, vibration damping lower limit
The high problem of frequency.
After the good mechanical oscillation body of suspended fixing, under the effect of gravity, the upper elastic body 4 is in tensional state, under described
Elastomer 5 is in compressive state, therefore, can be avoided and upper elastic body 4 or lower elastic body 5 and 3 bonding plane of bracket 1 or dynamic core occurs
When the extreme case to fall off, being suspended structure will not slump.
The dynamic core 3 is equipped with the mounting hole 32 with inner hole 2 in the same direction and for being threadedly coupled with external vibration body, passes through spiral shell
External mechanical oscillation body is installed on the damper by line connection, simple and convenient；Due to the dynamic core 3 and 2 inner wall phase of inner hole point
From the left and right sides of the upper elastic body 4 and lower elastic body 5 is mutually separated with 2 left and right sidewall of inner hole respectively, then moves core 3 and inner hole
There is certain gap between 2 inner walls, between 2 left and right sidewall of upper elastic body 4 and lower elastic body 5 and inner hole, the dynamic core 3 is only
It is connect by upper elastic body 4 and lower elastic body 5 with bracket 1, the dynamic core 3 can all around be translatable or along vertical in inner hole 2
Axis rotation enables dynamic core 3 that fraction of movement and torsion occurs, has in the case where mounting hole 32 has a small amount of dislocation fault-tolerant
Ability.
The left and right width of the upper elastic body 4 and lower elastic body 5 is less than the left and right width of dynamic core 3, convenient for moving the torsion of core 3
Turn.
The positive stop lug boss 31 of protrusion is respectively equipped in the middle part of the left and right sides of the dynamic core 3, the limitation of positive stop lug boss 31 is dynamic
Gap between 2 side wall of core 3 and inner hole, so as to limit the amplitude of dynamic 3 double swerve of core.Preferably, the positive stop lug boss
31 be soft elastic material, avoids dynamic core 3 and 2 side wall hard collision of inner hole.
The bracket 1 includes the flange mounting portion 11 for being fixed on the damper in external structure, the method
Ring part 12 that is that blue mounting portion 11 is equipped with protrusion and being used to form inner hole 2, structure is simple.
When specifically used, which can be used for the installation of soundproof door, sound proof window, the level side of damp low frequency sound wave excitation
To vibration, block all-bottom sound to the transmitting of building structure.The damper can also be used in the installation of metope sound insulating layer, damp low frequency sound
The horizontal direction vibration of wave excitation, blocks all-bottom sound to the transmitting of building structure.The damper can also be used in other and need level
The suspended fixing of the mechanical oscillation body of direction low frequency vibration damping.
