[0001] The utility model relates to the technical field of sound-absorbing and sound-absorbing structures, in particular to a metal wedge structure with holes. Background Art

[0002] The commonly used sound-absorbing wedges at present are glass wool wedges, which are made of steel wire as the skeleton, filled with glass wool or other sound-absorbing materials, and covered with glass cloth, plastic window screen or textile cloth and other surface materials. This is a traditional sound-absorbing wedge method, which is characterized by easy hand-made, low material cost and processing cost. The disadvantages are uneven outer surface, monotonous color, poor waterproof and dustproof performance, difficult to clean, short service life, difficult installation, difficult to disassemble and reassemble quickly, cannot be industrialized and mass-produced, large wedges are easy to deform and internal glass fibers are easy to overflow.

[0003] Traditional metal wedges use perforated steel plates as the surface of the wedges, and fill the inside of the wedges with sound-absorbing cotton, among which the most commonly used sound-absorbing cotton is glass fiber sound-absorbing cotton. The main features of this type of metal wedges are neat and beautiful appearance, good stability, and good sound absorption at the perforated places on the surface of the metal wedges. However, since there are also unperforated parts on the perforated steel plates on the surface of the metal wedges, it is this part that is prone to sound reflection, which affects the sound absorption performance and causes the sound absorption rate to deteriorate. Utility Model Content

[0006] As a preferred solution, a plurality of first sound-absorbing holes are formed on the first arc-shaped groove, and the first sound-absorbing holes are distributed in a matrix on the arc-shaped surface of the first arc-shaped groove.

[0007] As a preferred solution, a plurality of second sound-absorbing holes are formed on the second arc-shaped groove, and the second sound-absorbing holes are distributed in a matrix on the arc-shaped surface of the second arc-shaped groove.

[0008] As a preferred solution, a plurality of third muffler holes are provided on the inwardly concave curved surfaces on the outer surfaces of both sides of each of the pointed portions.

[0009] As a preferred solution, a receiving groove is provided on the tip, and the receiving groove is provided on the side of the tip, and each side of the tip has a receiving groove, and the multiple receiving grooves are located at the same height of the horizontal plane of the base.

[0010] As a preferred solution, a filling block is installed in the accommodating groove, and the filling block is glass fiber sound-absorbing cotton, polyester fiber sound-absorbing cotton or melamine sound-absorbing cotton.

[0011] As a preferred solution, the connecting rod is provided with threads, the clamping block cooperates with the connecting rod threads, and the left and right clamping blocks located on both sides of the tip cooperate with the connecting rod to connect the tip and the connecting rod as a whole.

[0012] As a preferred solution, the hole distance between each of the first sound-absorbing hole, the second sound-absorbing hole and the third sound-absorbing hole ranges from three millimeters to ten millimeters.

[0013] The utility model is beneficial in that:

[0014] Arc-shaped grooves are chosen to be opened on the four sides of the base, front, back, left and right. On the one hand, the contact area with the sound can be increased to provide more points and surfaces for diffusion; on the other hand, the two arc-shaped grooves can reduce the overall weight to the greatest extent, so that it is more labor-saving during subsequent installation.

[0021] like Figure 1 and Figure 2 As shown,

[0022] As an optional embodiment:

[0023] A perforated metal wedge structure comprises a base 100 and a plurality of tips 200 connected to the base 100, wherein the front and rear sides of the base 100 are provided with a first arcuate groove 101, the left and right sides of the base 100 are provided with a second arcuate groove 102, each of the tips 200 is wedge-shaped, and the outer surfaces of both sides of each of the tips 200 are inwardly concave curved surfaces, each of the tips 200 is provided with a mounting hole 203, a connecting rod 4 is installed in the mounting hole 203, a clamping block 5 is sleeved on the connecting rod 4 and on both sides of the tip 200, and the two clamping blocks 5 on both sides of the tip 200 are fixed on the connecting rod 4 to clamp the tip 200.

[0024] In the above structure, the base 100 is used, and arc grooves are opened on the four sides of the base 100, specifically, the first arc groove 101 is opened on the front and back sides of the base 100, and the second arc groove 102 is opened on the left and right sides of the base 100. The first arc groove 101 and the second arc groove 102 can increase the contact area with the sound and provide more points and surfaces for diffusion. On the other hand, the two arc grooves can reduce the overall weight to the greatest extent, so that it is more labor-saving during subsequent installation.

[0025] Second, the tip 200 is supported by the base 100, and the two are fixedly connected as one. A plurality of tips 200 are designed, and each tip 200 is distributed on the top surface of the base 100 at equal intervals, and each tip 200 is fixedly connected to the base 100. In order to fix the top of the tip 200, a mounting hole 203 is selected to be opened on the side of the tip 200. Subsequently, the connecting rod 4 is sequentially passed through the plurality of mounting holes 203. In order to lock the position of each tip 200, a plurality of clamping blocks 5 are sleeved on the connecting rod 4. Two clamping blocks 5 form a group, and the two clamping blocks 5 of each group are located on both sides of the corresponding tip 200. The two clamping blocks 5 located on both sides of the tip 200 clamp and fix the tip 200. Subsequently, the clamping blocks 5 are fixed on the connecting rod 4. The two adjacent tips 200 are positioned by the same connecting rod 4, so that the plurality of tips 200 are connected as one, and the stability of the ends of the tips 200 is achieved.

[0026] Third, the outer surfaces of both sides of each of the pointed parts 200 are inwardly concave curved surfaces, which increases the contact area between the pointed part and the sound.

[0027] Based on the first embodiment, Figure 1 As shown:

[0028] The first arc-shaped groove 101 is provided with a plurality of first sound-absorbing holes 1011, and the first sound-absorbing holes 1011 are distributed in a matrix on the arc-shaped surface of the first arc-shaped groove 101; preferably, the second arc-shaped groove 102 is provided with a plurality of second sound-absorbing holes 1021, and the second sound-absorbing holes 1021 are distributed in a matrix on the arc-shaped surface of the second arc-shaped groove 102; preferably, a plurality of third sound-absorbing holes 202 are provided on the inwardly concave curved surface on the outer surfaces of both sides of each of the tip 200; preferably, the plurality of first sound-absorbing holes 1011, the plurality of second sound-absorbing holes 1021 and the plurality of third sound-absorbing holes 202 can all better absorb sound and, in addition, can reduce the overall weight.

[0029] Based on the first embodiment, Figure 2 As shown:

[0031] A filling block 300 is installed in the receiving groove 201 , and the filling block 300 is glass fiber sound-absorbing cotton, polyester fiber sound-absorbing cotton or melamine sound-absorbing cotton.

[0032] The receiving groove 201 provides more points and surfaces for diffusion, which is beneficial to converting sound energy into heat energy and achieving a better attraction effect. It is also very effective in reducing sound reflection, eliminating standing waves, reducing reverberation, and echoes.

[0033] The connecting rod 4 is provided with threads, and the clamping block 5 is threadedly matched with the connecting rod 4 . The left and right clamping blocks 5 located on both sides of the tip 200 will cooperate with the connecting rod 4 to connect the tip 200 and the connecting rod 4 into one.

[0034] The clamping block 5 is selected to rotate on the connecting rod 4 , and the clamping block 5 is threadedly connected to the connecting rod 4 . Subsequently, the left and right clamping blocks 5 can position the tip 200 to limit the shaking of the end of the tip 200 .

[0035] The hole spacing of each of the first muffler hole 1011, the second muffler hole 1021 and the third muffler hole 202 is between three millimeters and ten millimeters, which can reduce the overall weight while achieving better sound insulation.
