Abstract
The utility model discloses a sound-proof box used for noise test. The sound-proof box includes a pedestal, universal rollers, a rubber damping cushion, an outer sound-proof wall, an outer sound-proof door, an air layer, damping spring groups, an inner sound-proof wall, and an inner sound-proof door. The inside of the outer sound-proof wall is provided with the inner sound-proof wall. The air layer is arranged between the two sound-proof walls. The damping springs are arranged between the outer sound-proof wall and the inner sound-proof wall. The rubber damping cushion is arranged between the outer sound-proof wall and the pedestal. The sound-proof box can reduce the noise by 70 decibels, and the lowest ambient noise in the sound-proof box is 15 decibels, so the sound-proof box can satisfy the noise test with high requirements.
Description
Technical field
The utility model relates to a kind of sound arrester, particularly a kind of test noise soundproof box.
Background technology
At present, the soundproof box that test noise uses only has the compound sound-insulation wall of individual layer, the individual layer sound-insulation wall is subject to the oise insulation factor restriction of material, the oise insulation factor of the compound sound-insulation wall of individual layer is the highest can only to reach 40 decibels, and the internal environment noise is minimum can only to reach 25 decibels, can't reach the requirement of high standard test environment.
The utility model content
Goal of the invention of the present utility model is: overcome the deficiencies in the prior art, for the problem of above-mentioned existence, provide a kind of soundproof effect good soundproof box.
The technical solution adopted in the utility model is such: a kind of test noise soundproof box comprises base, universal rolling wheel, Rubber shock-absorbing pad, outer sound-insulation wall, outer soundproof door, damping spring group, internal layer sound-insulation wall, internal layer soundproof door.In outer sound-insulation wall, also be provided with the internal layer sound-insulation wall, leave air layer between the inside and outside two-layer sound-insulation wall.Damping spring is arranged between the outer bottom of outer sound-proof wall inner bottom surface and internal layer sound-proof wall.Between the bottom surface of outer sound-proof wall and base, be provided with Rubber shock-absorbing pad.
In sum, owing to adopted technique scheme, the beneficial effects of the utility model are:
1, between base and outer sound-proof wall, Rubber shock-absorbing pad is set, has reduced the impact of earth shock on soundproof box.
2, the internal layer sound-insulation wall is made suspension structure, and utilize the decay of sound in the Double-layer sound-insulation body of wall, and the consumption in air layer, but 70 decibels of soundproof box integral body noise reductions, neighbourhood noise is minimum in the soundproof box reaches 15 decibels, can satisfy the noise testing of high request.
Description of drawings
Fig. 1 is the cut-open view that soundproof box is used in a kind of noise testing.
Mark among the figure: 1 is base, and 2 is universal rolling wheel, and 3 is beam, and 4 is outer sound-insulation wall, and 5 is outer soundproof door, and 6 is air layer, and 7 is the damping spring group, and 8 is the internal layer sound-insulation wall, and 9 is the internal layer soundproof door.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
As shown in Figure 1, a kind of test noise soundproof box comprises base 1, universal rolling wheel 2, beam 3, outer sound-insulation wall 4, outer soundproof door 5, air layer 6, damping spring group 7, internal layer sound-insulation wall 8, internal layer soundproof door 9.4 universal rolling wheels 2 are installed, convenient mobile and transportation below the base 1.Outer sound-insulation wall 4 thickness are 100mm～200mm.Outer soundproof door 5 thickness are consistent with outer sound-proof wall body, and 6 of outer soundproof door 5 and outer sound-insulation walls are hinged, and crack between a door and its frame adopts multi-fold structure, and the sealing strip sealing that is magnetic.Be provided with internal layer sound-proof wall 8 in the inside of outer sound-proof wall 4, internal layer sound-proof wall 8 thickness are 100mm～200mm.The internal layer soundproof door is consistent with internal layer sound-proof wall body 8 by 9 thickness, and 8 of internal layer soundproof door 9 and internal layer sound-insulation walls are hinged, and crack between a door and its frame adopts multi-fold structure, and the sealing strip sealing that is magnetic.Outer sound- proof wall body 4 and 8 of internal layer sound-proof wall bodies leave the air layer 6 of 10mm.The thick Rubber shock-absorbing pad of 10mm 3 is installed between base 1 and the outer sound-insulation wall 4, reduces earth shock to the impact of soundproof box.The high damping spring group 7 of 100mm is installed between the bottom surface of the following and outer sound-insulation wall 4 of internal layer sound-insulation wall 8.Noise imports air layer 6 into from outer sound-proof wall body 4, effective attenuation in air layer 6, and damping spring group 7 has effectively been isolated the vibrations that outer sound-insulation wall 4 produces.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
