Abstract
The invention discloses a height-adjustable sound-absorbing wedge, which comprises a base part and a pointed part connected with the base part, wherein the pointed part consists of at least two connecting blocks; adjacent connecting blocks are detachably connected with each other. According to the height-adjustable sound-absorbing wedge, connecting pieces can be arranged or detached according to different requirements to adjust the height of the wedge, so that the size of a silencing room is increased to accommodate larger test products, the test distance can be increased, and various requirements are met.
Description
Technical field
The present invention relates to a kind of wedge, relate in particular to a kind of height-adjustable sound-absorbing wedge.
Background technology
The sound-absorbing wedge is to build the essential sound absorption construction of micron order sound attenuation room.Adopt the sound-absorbing wedge, can obtain the high-effect sound absorption characteristics of the broadband that comprises low frequency, the sound attenuation room cut-off frequency generally can reach the 60-70 hertz.The cut-off frequency that the concrete specification of sound-absorbing wedge is absorbed by needs determines, absorption frequency is lower, the length of wedge just needs higher, and the acoustics experiment of general high request can be low to moderate 60HZ with the sound attenuation room cut-off frequency, and it is the 100HZ left and right that enterprise measures noises sound attenuation room cut-off frequency.The sound-absorbing wedge generally has three kinds of materials to make, and is respectively mineral fibers, foam and metal, and traditional metal wedge, its as a whole design, and its tip is integrated, height can't change.So, can't meet diversified demand.
Summary of the invention
The object of the invention is to for above-mentioned defect of the prior art, a kind of height-adjustable sound-absorbing wedge is provided, it can allow the size of anechoic chamber become large, in order to place larger test products, also can increase measuring distance, has met diversified demand.
For achieving the above object, the present invention has adopted following technical scheme: a kind of height-adjustable sound-absorbing wedge, comprise base portion and the tip be connected with base portion, it is characterized in that: described tip is comprised of at least two contiguous blocks, and mutually removably connects between adjacent contiguous block.
In addition, the present invention also provides following attached technical scheme:
Be provided with slot and the convex shoulder of mutual buckle between described adjacent two contiguous blocks.
Described height-adjustable sound-absorbing wedge is formed by the metal material manufacture.
The surface of described height-adjustable sound-absorbing wedge is fixedly connected with punched steel plate.
Than prior art, advantage of the present invention is: the tip of this height-adjustable sound-absorbing wedge is by being comprised of at least two contiguous blocks, and removably connection mutually between adjacent contiguous block.So this height-adjustable sound-absorbing wedge can to regulate its height, thereby allow the size of anechoic chamber become large according to the different installation or removal connectors that need, in order to place larger test products, also can increase measuring distance, has met diversified demand.
The accompanying drawing explanation
Fig. 1 is the height-adjustable sound-absorbing wedge stereogram corresponding to preferred embodiment of the present invention.
Fig. 2 is the component exploded view of Fig. 1.
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.
Embodiment 1: see figures.1.and.2, corresponding to the sound-absorbing wedge of the adjustment height of preferred embodiment of the present invention, it is the essential sound absorption construction in anechoic chamber.It comprises base portion 3 and tip 4, and wherein, tip 4 is comprised of at least two connectors.In the present embodiment, the optimal number of connector is 3, and it is respectively connector 4a, connector 4b and connector 4c.
Particularly, connector 4a and base portion 3 are fixedly connected, and its bottom position is provided with slot 7.That adjacent with connector 4a is connector 4b, and the apical position of connector 4b is provided with convex shoulder 9, and bottom position is provided with slot 7 ' simultaneously.That adjacent with connector 4b is connector 4c, and the apical position of connector 4c is provided with convex shoulder 9 '.Wherein, slot 7,7 ' is downward extended twice chute from the both sides, bottom of connector 4a, 4b; Convex shoulder 9,9 ' is the twice convex shoulder that the both sides, top from connector 4b, 4c extend outward.
During installation, mutual buckle between adjacent connector.Particularly, in the slot 7 that the convex shoulder 9 on connector 4b inserts on connector 4b, in the slot 7 ' that the convex shoulder 9 ' on connector 4c inserts on connector 4b.And, when needs change height, only convex shoulder 9,9 ' need be got final product from extracting in slot 7,7 ' respectively.
Sound-absorbing wedge corresponding to the adjustment height of preferred embodiment of the present invention is formed by the metal material manufacture, and its surface is fixedly connected with punched steel plate.Connected mode includes but not limited to that welding, screwing is connected with rivet.
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.
Claims (4)
1. a height-adjustable sound-absorbing wedge, comprise base portion and the tip be connected with base portion, and it is characterized in that: described tip is comprised of at least two contiguous blocks, and mutually removably connect between adjacent contiguous block.
2. height-adjustable sound-absorbing wedge according to claim 1, is characterized in that: the slot and the convex shoulder that are provided with mutual buckle between described adjacent two contiguous blocks.
3. height-adjustable sound-absorbing wedge according to claim 1, is characterized in that it is formed by the metal material manufacture.
