Abstract
The utility model relates to a vibration damper plate of making an uproar falls in sound of inhaling in elevator car belongs to the vibration damper plate field, including the plate body, its characterized in that, the surface of plate body is equipped with the buffer layer, the middle part of plate body sets up a plurality of low intermediate frequencies and inhales the sound cavity, and each low intermediate frequency inhales that the sound cavity is inside to set up an abatvoix, and set up two on the abatvoix and inhale the sound hole, the edge of plate body sets up a plurality of high frequencies and inhales the sound cavity. The utility model discloses inhale the sound and fall the transformation of making an uproar on the vibration damper plate, on the basis that does not increase wall body thickness, reach the effect that the absorbing reduces low frequency, intermediate frequency, high frequency noise simultaneously.
Description
Technical field
The utility model relates to a kind of vibration damper plate, specifically, is the absorbing sound and lowering noise vibration damper plate in a kind of lift car.
Background technology
The noise produced in running process of elevator is one of main source of life noise, is generally all provided with vibration damper plate and insulation board and panel in present lift car, and the friction over a long time between vibration damper plate and insulation board and panel, easily damage shock reducing structure, reduce damping, soundproof effect.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides the vibration damper plate of the absorbing sound and lowering noise in a kind of lift car.
For achieving the above object, the utility model provides following technical scheme:
The utility model relates to the absorbing sound and lowering noise vibration damper plate in a kind of lift car, comprise plate body, it is characterized in that, the surface of described plate body is provided with buffer layer, the middle part of described plate body arranges some Low Medium Frequency sound-absorbing cavitys, each Low Medium Frequency sound-absorbing cavity inside arranges one block of abatvoix, abatvoix is arranged two sound-absorption hole, and the edge of described plate body arranges some high frequency sound-absorbing cavitys.
As further scheme of the present utility model, described buffer layer is the damping net that some shock reducing structures are woven into.
As further scheme of the present utility model, described shock reducing structure is regular hexagon, comprise several eyelets, hole wall is formed between adjacent described eyelet, the inside of described hole wall is embedded with spring, the setting direction of described spring is perpendicular to the upper surface of described shock reducing structure, and the length of described spring is less than the thickness of described shock reducing structure.
As further scheme of the present utility model, in described Low Medium Frequency sound-absorbing cavity, fill centrifugally glass-wool or rock wool.
As further scheme of the present utility model, described abatvoix adopts polyester fiber board.
As further scheme of the present utility model, in described high frequency sound-absorbing cavity, fill slackness wool.
Compared with prior art, good effect of the present utility model is:
1. the utility model carries out the transformation of absorbing sound and lowering noise on vibration damper plate, is not increasing on the basis of thickness of wall body, reduces the effect of low frequency, intermediate frequency, high frequency noise while reaching damping.
Accompanying drawing explanation
Fig. 1 is the cutaway view of the absorbing sound and lowering noise vibration damper plate in a kind of lift car;
Fig. 2 is the structural representation of described shock reducing structure.
Mark in accompanying drawing 1 is respectively: 1. plate body; 2. intermediate frequency sound-absorbing cavity; 3. abatvoix; 4. high frequency sound-absorbing cavity; 5. sound-absorption hole; 6. buffer layer; 7. shock reducing structure; 8. eyelet; 9. spring; 10. hole wall.
Detailed description of the invention
The technological means realized to make the utility model, character of innovation, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
As shown in Figure 1, 2, absorbing sound and lowering noise vibration damper plate in a kind of lift car, comprise rectangle warming plate plate body 1, it is characterized in that, the middle part of described plate body 1 arranges some Low Medium Frequency sound-absorbing cavitys 2, each Low Medium Frequency sound-absorbing cavity 2 inside arranges one block of abatvoix 3, abatvoix 3 is arranged two sound-absorption hole 5, and the edge of described plate body 1 arranges some high frequency sound-absorbing cavitys 4.
Wherein, centrifugally glass-wool or rock wool is filled in described Low Medium Frequency sound-absorbing cavity 2.
Wherein, described abatvoix 3 adopts polyester fiber board.
Wherein, slackness wool is filled in described high frequency sound-absorbing cavity 4.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, therefore all changes be intended in the implication of the equivalency by dropping on claim and scope are included in the utility model, any Reference numeral in claim should be considered as the claim involved by limiting.
