FIG. 1 is a schematic diagram of the structure of one embodiment of a sound absorbing wedge of the present invention.
Fig. 2 is a left side view of the sound absorbing wedge of fig. 1.
Detailed Description
The present invention will be described in further non-limiting detail with reference to the following preferred embodiments and accompanying drawings.
As shown in fig. 1 and 2, a sound-absorbing wedge according to a preferred embodiment of the present invention includes a frame 1, a sound-absorbing material 2 and an adjusting device 10, both disposed in the frame 1.
The frame 1 is made of elastic materials and has certain elastic restoring force, preferably a plastic-sprayed steel wire frame, a protective surface made of glass fiber cloth, nylon wire mesh cloth or other cloth materials is covered outside the plastic-sprayed steel wire frame, and the frame 1 can also be made of perforated metal plates. The sound-absorbing material 2 is preferably made of sound-absorbing glass wool, which can be attached to the inner surface of the frame 1 by gluing.
The frame 1 is wedge-shaped as a whole and comprises a first side surface 3, a first inclined surface 4, a second inclined surface 5 and a second side surface 6 which are connected in sequence, wherein the first side surface 3 and the second side surface 6 are parallel to each other, the first inclined surface 4 and the second inclined surface 5 are in fillet transition, an included angle 7 is formed between the two inclined surfaces, and the width of the bottom of the sound-absorbing wedge (namely the distance between the first side surface 3 and the second side surface 6) is adjustable.
The first side surface 3 is connected with a first fixing frame 30, the first fixing frame and the first fixing frame can be connected through a feasible connection mode in the prior art such as bolt connection, riveting or welding, the first fixing frame 30 is made of bent sheet metal, and a horizontal first groove 31 is formed in the center of the first fixing frame. Similarly, a second fixing frame 40 is connected to the second side surface 6, and preferably, the second fixing frame 40 is symmetrical to the first fixing frame 30 and is also provided with a horizontal second groove 41. The sound-absorbing wedge is provided with a first end surface 1a and a second end surface 1b in the longitudinal direction, and preferably, the first groove 31 and the second groove 41 extend from the first end surface 1a to the second end surface 1 b.
In one embodiment, the first side surface 3, the first inclined surface 4, the second inclined surface 5, and the second side surface 6 are formed as one body and are formed by bending the frame 1.
The adjusting device 10 is disposed between the first side surface 3 and the second side surface 6, and can expand or reduce the distance between the first side surface 3 and the second side surface 6, thereby changing the size of the included angle 7 between the first side surface 3 and the second side surface 6.
The adjustment device 10 may have a variety of possible configurations, and in one embodiment, as shown in FIG. 1, the adjustment device 10 includes a first stud 11 coupled to the first side 3, a second stud 12 coupled to the second side 6, and a threaded sleeve 13 coupled between the first stud 11 and the second stud 12.
Specifically, the first stud 11 includes a first push plate 14, the first stud 11 is disposed on the first side surface 3 in a penetrating manner, and the first push plate 14 is disposed in the first groove 31; the second stud 12 includes a second push plate 15, the second stud 12 is disposed on the second side surface 6, the second push plate 15 is disposed in the second groove 41, and preferably, the first push plate 14 extends from the first end surface 1a to the second end surface 1 b. The screw sleeve 13 is in threaded connection with the first stud 11 and the second stud 12, the thread directions of the first stud 11 and the second stud 12 are opposite, and if the thread of the first stud 11 is a right-hand thread, the second stud 12 is a left-hand thread; conversely, if the first stud 11 is threaded left-hand, the second stud 12 is threaded right-hand. Thus, after the screw 13 is rotated, the first and second push plates 14 and 15 pull the first and second side surfaces 3 and 6 toward each other or move the first and second side surfaces 3 and 6 away from each other by the elastic force between the first and second side surfaces 3 and 6. This action causes a deformation between the first 5 and second 6 side surfaces and a change in the angle of the included angle 7. Because the first push plate 14 and the second push plate 15 have longer lengths, the first side surface 3 and the second side surface 6 are not easy to deform, the vertical state can be well kept, the sound-absorbing wedges are convenient to arrange in order, and under the condition that an integral number of conventional sound-absorbing wedges cannot be installed on a wall surface, the sound-absorbing wedges can be fully distributed on the wall surface by changing the width of the bottom, so that a better acoustic effect is achieved; in addition, the cooperation of the first push plate 14 and the first groove 31 and the cooperation of the second push plate 15 and the second groove 41 can prevent the first stud 11 and/or the second stud 12 from following when the screw sleeve 13 is rotated.
Preferably, the outer surface of the threaded sleeve 13 is in a regular hexagonal prism shape, so that a person can conveniently hold the threaded sleeve to rotate the threaded sleeve by a hand or rotate the threaded sleeve by a tool such as a wrench.
The invention has the following advantages:
1. the adjusting device capable of adjusting the width of the bottom of the sound-absorbing wedge (namely the distance between the first side surface and the second side surface) is arranged, so that when the sound-absorbing wedge is arranged on a wall surface, the whole wall can be arranged, and a gap is not reserved to influence the acoustic effect;
2. the adjusting device can also adjust the included angle of the sound-absorbing wedge, so that the sound-absorbing effect of the sound-absorbing wedge can be adjusted, the sound-absorbing wedge is laid after the angle is adjusted, and the acoustic effect of the anechoic chamber can be changed.
It should be noted that the above-mentioned preferred embodiments are merely illustrative of the technical concepts and features of the present invention, and are intended to enable those skilled in the art to understand the contents of the present invention and implement the present invention, and not to limit the scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
