Compared with the prior art, the present invention has the advantages that
1. the present invention be provided with can adjust sound absorption wedge bottom width (i.e. between first side and second side away from
From) regulating device so that full whole face wall can be arranged, without reserving sky when sound absorption wedge is arranged on metope
Gap influences acoustic efficiency；
2. regulating device of the invention is also adjustable the angle of sound absorption wedge angle, so as to adjust sound absorption wedge itself
Sound-absorbing effect, be laid with after sound absorption wedge is adjusted the angle, the acoustic efficiency of anechoic chamber can be changed.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of embodiment of sound absorption wedge of the present invention.
Fig. 2 is the left view of sound absorption wedge in Fig. 1.
Specific embodiment
In conjunction with the preferred embodiment and its attached drawing is further non-limitingly described in detail technical solution of the present invention.
As depicted in figs. 1 and 2, corresponding to a kind of sound absorption wedge of present pre-ferred embodiments comprising frame 1 is all provided with
The sound-absorbing material 2 and regulating device 10 being placed in frame 1.
Frame 1 is made of elastic material, has certain elastic restoring force, preferably plastic-spraying steel wire rack, plastic-spraying steel wire
Frame is cladded with the mask made of glass wool cloth, nylon yarn screen cloth or other cloth materials, and perforated metal also can be used in frame 1
It is made.The material of sound-absorbing material 2 preferably uses sound-absorbing mineral wool, can be connect by way of gluing with 1 inner surface of frame.
Whole frame 1 is in wedgelike comprising sequentially connected first side 3, the first inclined-plane 4, the second inclined-plane 5 and second
Side 6, wherein first side 3 and second side 6 are parallel to each other, and the first inclined-plane 4 and the second inclined-plane 5 have round-corner transition, and two
Angle 7, the bottom width (i.e. the distance between first side 3 and second side 6) of sound absorption wedge of the present invention are formed between inclined-plane
It is adjustable.
It is connected with the first fixed frame 30 in first side 3, the prior arts such as the two can be bolted, rivet or weld
In feasible connection type be attached, the first fixed frame 30 is made of metal plate bending, and it is recessed that center offers horizontal first
Slot 31.Likewise, being connected with the second fixed frame 40 in second side 6, preferably the second fixed frame 40 and the first fixed frame 30 are symmetrical,
It also offers the second horizontal groove 41.Sound absorption wedge is provided with first end face 1a and second end face 1b in length direction, excellent
Choosing, the first groove 31 and the second groove 41 extend to second end face 1b from first end face 1a.
In one embodiment, first side 3, the first inclined-plane 4, the second inclined-plane 5 and second side 6 are integral type, by
Frame 1 passes through bending and molding.
Regulating device 10 is set between first side 3 and second side 6, can expand or shrink first side 3 and
The distance between two side faces 6, and then change the size of angle 7 between first side 3 and second side 6.
Regulating device 10 can there are many feasible structures, in one embodiment, as shown in Figure 1, regulating device 10
Including the first stud 11 being connected with first side 3, the second stud 12 being connected with second side 6 and it is connected to the first stud
11 and the second swivel nut 13 between stud 12.
Specifically, the first stud 11 includes the first push plate 14, the first stud 11 is threaded through in first side 3, and first pushes away
Plate 14 is set in the first groove 31；Second stud 12 includes the second push plate 15, and the second stud 12 is threaded through in second side 6,
Its second push plate 15 is set in the second groove 31, it is preferred that the first push plate 14 extends to second end face 1b from first end face 1a.
Swivel nut 13 is then threadedly coupled with the first stud 11 and the second stud 12, also, the screw thread side of the first stud 11 and the second stud 12
To on the contrary, then the second stud 12 is left hand thread if 11 screw thread of the first stud is right-handed thread；On the contrary, if the first stud
11 screw threads are left hand thread, then the second stud 12 is right-handed thread.In this way, after rotating swivel nut 13, the first push plate 14 and
Two push plates 15 pull first side 3 and second side 6 close to each other, or make first side 3 and second side 6 in first side
It is located remotely from each other under resilient force between 3 and second side 6.Above-mentioned movement can cause first side 5 and second side 6 it
Between deformation occurs and changes the angle of angle 7.Since the first push plate 14 and the second push plate 15 have longer length, the
One, second side 3,6 is not susceptible to deform, and can keep vertical state well, facilitates the arrangement that sound absorption wedge is neat, in metope
In the case where the conventional sound absorption wedge of integer can not be installed, sound absorption wedge of the invention can be made by the width of change bottom
Metope can be covered with by obtaining sound absorption wedge, reach better acoustic efficiency；In addition, the first push plate 14 and the cooperation of the first groove 31 with
And second push plate 15 and the cooperation of the second groove 41 can prevent the first stud 11 and/or second when rotating swivel nut 13
12 transfer of stud.
Preferably, the outer surface of swivel nut 13 is in regular hexagonal prism shape, to facilitate manpower gripping to be rotated, or by spanner
Equal tools rotation.
The present invention at least has following advantage:
1. the present invention be provided with can adjust sound absorption wedge bottom width (i.e. between first side and second side away from
From) regulating device so that full whole face wall can be arranged, without reserving sky when sound absorption wedge is arranged on metope
Gap influences acoustic efficiency；
2. regulating device of the invention is also adjustable the angle of sound absorption wedge angle, so as to adjust sound absorption wedge itself
Sound-absorbing effect, be laid with after sound absorption wedge is adjusted the angle, the acoustic efficiency of anechoic chamber can be changed.
It is pointed out that the technical concepts and features of above-mentioned preferred embodiment only to illustrate the invention, its object is to
Those skilled in the art can understand the contents of the present invention and implements accordingly, and protection of the invention can not be limited with this
Range.Any equivalent change or modification in accordance with the spirit of the invention should be covered by the protection scope of the present invention.
