Abstract
The invention discloses an anechoic chamber. The anechoic chamber comprises walls and sound-absorption wedges, wherein the sound-absorption wedges are arranged on the inner sides of the walls; grids are arranged on the inner sides of the walls; each sound-absorption wedge comprises a hook; and the hooks are detachably connected with the grids in a matched manner. The sound-absorption wedges in the anechoic chamber are convenient to mount, are detachable, and are easy to reuse, so that the cost is saved.
Description
Technical field
The present invention relates to a kind of anechoic chamber.
Background technology
Anechoic chamber is a kind of acoustic measurement environment, and the sound-absorbing wedge be arranged in anechoic chamber is the indispensable building block in anechoic chamber, and it is suspended on the surroundings wall of anechoic chamber, for absorbing sound wave.Wherein, the chief component of sound-absorbing wedge has skeleton and damping material, and skeleton is a kind of by the reinforcing bar sound-absorbing wedge framework that is welded, and damping material is filled in the inside of this skeleton, finally uses sound-absorbing cloth that it is wrapped up to moulding.Yet in the prior art, the mounting means of sound-absorbing wedge is generally direct welding or uses swell fixture that it is fixedly connected on the inboard body of wall in anechoic chamber.But such connected mode has the difficulty of installation and non-removable shortcoming, once this anechoic chamber stops using, the sound-absorbing wedge in it is difficult to reclaim so, is unfavorable for again utilizing.
Summary of the invention
The object of the invention is to, for above-mentioned defect of the prior art, provides a kind of modified anechoic chamber, and the sound-absorbing wedge in it is easy for installation, and detachable, is convenient to recycle, cost-saving.
For achieving the above object, the present invention has adopted following technical scheme: a kind of anechoic chamber, comprise body of wall and be arranged on the sound-absorbing wedge on the body of wall inboard, it is characterized in that: described body of wall inboard arranges grid, described sound-absorbing wedge comprises hook, and described hook is removably matched with described grid.
In addition, the present invention also provides following attached technical scheme:
Described sound-absorbing wedge comprises base portion and the tip be connected with base portion, and described hook and described base portion are matched.
Described hook is mutually vertical with the bottom surface of described base portion.
The optimal number of described hook is 3.
Described hook is mutually vertical with the side of described base portion, and described hook is arranged on the same side of described base portion.
The optimal number of described hook is 2.
The best making of described grid material is round steel.
The size of described grid is identical with the base portion base area of described sound-absorbing wedge.
Than prior art, advantage of the present invention is: the body of wall inboard of this anechoic chamber arranges grid, and the sound-absorbing wedge arranges hook, and this hook is removably matched with grid.So the sound-absorbing wedge in this anechoic chamber is easy for installation, and detachable, be convenient to recycle, cost-saving.
The accompanying drawing explanation
Fig. 1 is corresponding to a kind of sound-absorbing wedge amplification stereogram in the anechoic chamber of preferred embodiment of the present invention.
Fig. 2 is corresponding to the another kind of sound-absorbing wedge amplification stereogram in the anechoic chamber of preferred embodiment of the present invention.
Fig. 3 is corresponding to the grid in the anechoic chamber of preferred embodiment of the present invention.
The specific embodiment
Below in conjunction with preferred embodiment and accompanying drawing thereof, technical solution of the present invention is further non-limitingly described in detail.
See figures.1.and.2, corresponding to the sound-absorbing wedge in the anechoic chamber of preferred embodiment of the present invention, it is mainly used in absorption of noise.This sound-absorbing wedge comprises base portion 2, the tip 3 be connected with base portion 2 and is arranged at least two hooks 5 on base portion 2.Wherein link up with 5 and be fixedly connected on the skeleton of base portion 2, the Best link mode is directly welding.
Particularly, sound-absorbing wedge 12 as shown in Figure 1, its hook 5 is mutually vertical with the bottom surface of base portion 2.In the present embodiment, linking up with 5 optimal number is 3, and two hooks 5 wherein are fixedly connected on Liang Ge base angle, 2 a certain bases of base portion, and another 5 of hook is fixedly connected on the mid point on base of base portion 2 opposite sides.Wherein, link up with 5 Liang Ge bases, place parallel to each other, and link up with 5 towards identical.
The sound-absorbing wedge 13 shown in Fig. 2 and for example, its hook 5 is mutually vertical with the side of base portion 2.In the present embodiment, linking up with 5 optimal number is 2, and it is fixedly mounted on respectively on the corner of base portion 2 some sides, and link up with 5 towards identical.
With reference to Fig. 3, corresponding to anechoic chamber's grid of preferred embodiment of the present invention, it is mainly used in hanging the sound-absorbing wedge.Grid 20 is fixedly connected on the inboard metope of anechoic chamber's surroundings wall equably, and with metope, certain distance is arranged, and only have in Fig. 3 on the part wall, grid 20 is installed, and main purpose is outstanding grid 20 and the effect of illustrating for simplicity.Particularly, it is round steel that the best of grid 20 is made material, and grid 20 comprises mesh 21, and the size of mesh 21 and shape are identical with the base portion 2 of sound-absorbing wedge 12,13.
Sound-absorbing wedge 12 is arranged on the grid 20 of anechoic chamber's end face, and sound-absorbing wedge 13 is arranged on the grid 20 of side, anechoic chamber.Concrete operation step is, by the base portion 2 of sound-absorbing wedge 12,13 toward the mesh 21 on hook 5 opposite direction offset grids 20, then will link up with 5 through mesh 20, then the positive direction toward hook 5 moves by sound-absorbing wedge 12,13, finally will link up with 5 and buckle on grid 20.Because sound-absorbing wedge 12 has 3 hooks 5, so it can stably be connected on grid 20, and sound-absorbing wedge 13 has a side of hook 5 upper, buckles on grid 20, and do not link up with a side of 5 under, abut against grid 20.During dismounting, only hook 5 need be broken away to grid 20, sound-absorbing wedge 12,13 can be taken out.
It is pointed out that above-mentioned preferred embodiment is only explanation technical conceive of the present invention and characteristics, its purpose is to allow the person skilled in the art can understand content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalences that Spirit Essence is done according to the present invention change or modify, within all should being encompassed in protection scope of the present invention.
