Abstract
The utility model discloses a height adjustable sound-absorbing wedge. The height adjustable sound-absorbing wedge comprises a base and a tip portion connected with the base. The tip portion is composed of at least two connection blocks and adjacent connection blocks can be mutually and detachably connected. Therefore, due to the fact that connection members of the height adjustable sound-absorbing wedge can be assembled or detached according to different needs so that heights of the connection members are adjusted, size of an anechoic chamber is increased to facilitate placing larger test productions and testing distances can be also increased; and therefore the need of diversification is satisfied.
Description
Technical field
The utility model relates to a kind of wedge, relates in particular to a kind of height-adjustable sound-absorbing wedge.
Background technology
Sound-absorbing wedge is to build the essential sound absorption construction of micron order sound attenuation room.Adopt sound-absorbing wedge, can obtain the high-effect sound absorption characteristics of broadband that comprise low frequency, sound attenuation room cut-off frequency generally can reach 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 sound attenuation room cut-off frequency, and it is 100HZ left and right that enterprise measures noises sound attenuation room cut-off frequency.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 cannot change.So, cannot meet diversified demand.
Utility model content
The purpose of this utility model is for above-mentioned defect of the prior art, and a kind of height-adjustable sound-absorbing wedge is provided, and it can allow the size of anechoic chamber become large, to place larger test products, also can increase measuring distance, has met diversified demand.
For realizing above-mentioned utility model object, the utility model has adopted following technical scheme: a kind of height-adjustable sound-absorbing wedge, comprise base portion and the tip being connected with base portion, it is characterized in that: described tip is comprised of at least two contiguous blocks, and mutually removably connect between adjacent contiguous block.
In addition, the utility model also provides following attached technical scheme:
Between described adjacent two contiguous blocks, be provided with slot and the convex shoulder of mutual buckle.
Described height-adjustable sound-absorbing wedge is formed by 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 utility model 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, to place larger test products, also can increase measuring distance, has met diversified demand.
Accompanying drawing explanation
Fig. 1 is the height-adjustable sound-absorbing wedge stereogram corresponding to the utility model preferred embodiment.
Fig. 2 is the component exploded view of Fig. 1.
The specific embodiment
Below in conjunction with preferred embodiment and accompanying drawing thereof, technical solutions of the utility model are further non-limitingly described in detail.
Embodiment 1: see figures.1.and.2, corresponding to the essential sound absorption construction in sound-absorbing wedge ，Qi Wei anechoic chamber of the adjustment height of the utility model preferred embodiment.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 the downward extended twice chute in both sides, bottom from 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 extracted respectively in slot 7,7 '.
Sound-absorbing wedge corresponding to the adjustment height of the utility model preferred embodiment is formed by 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 to be noted; above-mentioned preferred embodiment is only explanation technical conceive of the present utility model and feature; its object is to allow person skilled in the art can understand content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences of doing according to the utility model Spirit Essence change or modify, within all should being encompassed in protection domain of the present utility model.
