[0002] A wedge-shaped sound absorbing body with a very high sound absorption coefficient designed to achieve a gradual transition of the acoustic impedance between air and sound absorbing materials and obtain good impedance matching and sound absorption effects is called a sound absorbing wedge.

[0003] The sound absorbing wedge is a special sound absorbing body, which requires that the sound waves incident on its surface are almost completely absorbed. The sound absorbing wedge consists of a base and a wedge. The base is the bottom section with a constant cross section, and the wedge is the section with a gradually increasing cross section from the tip. Since the wedge section of the sound absorbing wedge gradually increases from a small size, it is more matched with the characteristic impedance of air, so that the incident sound waves are almost completely absorbed without any reflection.

[0004] The existing technology has the following problems:

[0005] In actual use, the existing sound-absorbing split-point panels have a complicated connection method, and operators need to go through multiple steps to connect the sound-absorbing split-point panels together. The connection speed is slow, which reduces work efficiency. At the same time, the stability of the connection between the sound-absorbing split-point panels cannot be well guaranteed, resulting in poor stability between the connected sound-absorbing split-point panels, which in turn causes low overall strength.

[0022] The present invention is further described in detail below in conjunction with the embodiments:

[0023] like Figure 1-4 As shown, the utility model provides a sound-absorbing wedge plate connection structure, including a sound-absorbing wedge plate 1, a sound-absorbing wedge plate 2 is installed at the right end of the sound-absorbing wedge plate 1, a docking block 3 is installed at the lower ends of the sound-absorbing wedge plate 1 and the sound-absorbing wedge plate 2, and a docking groove 4 is provided at the upper ends of the sound-absorbing wedge plate 1 and the sound-absorbing wedge plate 2. With the cooperation of the docking block 3 and the docking groove 4, the upper and lower ends of the sound-absorbing wedge plate can be quickly connected, and a connecting mechanism 5 is installed between the sound-absorbing wedge plate 1 and the sound-absorbing wedge plate 2.

[0024] The lower ends of the sound absorbing split plate 1 and the sound absorbing split plate 2 are fixedly connected to the upper end of the docking block 3.

[0025] The docking block 3 and the docking groove 4 are both in a "T" shape.

[0026] The docking block 3 matches with the docking groove 4 and is slidably connected.

[0027] Through the connecting mechanism 5, the positioning column 58 and the clamping block 59 can be docked with the positioning groove 56 and the clamping groove 57, so as to complete the preliminary connection, which makes the operation simple and the connection speed fast. At the same time, after the groove 51 forms a complete circle, the connection of the sound-absorbing split-point plate can be fixed by the circular plate 53 and the bolt 55, so as to improve the stability between the sound-absorbing split-point plates and make the overall strength higher.

[0028] like Figure 3-4 As shown, the connecting mechanism 5 includes a groove 51, and the front and rear four corners of the sound-absorbing split-point plate 1 and the sound-absorbing split-point plate 2 are symmetrically provided with grooves 51, and the bottom of the groove 51 is provided with a screw hole 52, and a circular plate 53 is installed inside the groove 51. The surface of the circular plate 53 is provided with four groups of through holes 54, and bolts 55 are movably inserted inside the through holes 54. Positioning grooves 56 are provided on the upper and lower sides of the left ends of the sound-absorbing split-point plate 1 and the sound-absorbing split-point plate 2, and a card slot 57 is provided in the middle of the left ends of the sound-absorbing split-point plate 1 and the sound-absorbing split-point plate 2, and positioning columns 58 are symmetrically installed on the upper and lower sides of the right ends of the sound-absorbing split-point plate 1 and the sound-absorbing split-point plate 2, and a card block 59 is installed in the middle of the right ends of the sound-absorbing split-point plate 1 and the sound-absorbing split-point plate 2, and elastic strips 510 are symmetrically fixedly installed on the front and rear sides of the card block 59.

[0029] The grooves 51 are arc-shaped, and four groups of grooves 51 can form a complete circle. The circular plate 53 is movably connected to the inside of the grooves 51 , and the bolts 55 are threadedly connected to the screw holes 52 .

[0032] When the block 59 is inserted into the slot 57, the elastic strip 510 will be squeezed by the front and rear inner walls of the slot 57. After the block 59 is fully inserted into the slot 57, the elastic strip 510 will be firmly in contact with the front and rear inner walls of the slot 57, thereby preliminarily fixing the sound-absorbing wedge plate so that it will not fall off during the connection process, thereby facilitating the connection.

[0033] The working principle of the sound-absorbing wedge plate connection structure is described in detail below.

[0034] like Figure 1-4 As shown, when the sound absorbing wedge plate connection structure is in use, when the sound absorbing wedge plates need to be connected, the right end of one group of sound absorbing wedge plates can be aligned with the left end of another group of sound absorbing wedge plates, so that the two groups of sound absorbing wedge plates are aligned, and the positioning column 58 and the clamping block 59 are respectively inserted into the positioning groove 56 and the clamping groove 57, so that the connection of the sound absorbing wedge plates can be completed, and then the docking block 3 can be inserted into the docking groove 4 on the sound absorbing wedge plate, and then the four groups of sound absorbing wedge plates can be connected, and at the same time, the grooves 51 on the four groups of sound absorbing wedge plates can form a complete circle, and then the circular plate 53 can be put into the circle, so that the position of the through hole 54 is aligned with the screw hole 52, and then the bolt 55 is inserted into the screw hole 52 through the through hole 54 and tightened, so that the four groups of sound absorbing wedge plates can be fixed, so that the stability between the four groups of sound absorbing wedge plates is improved, and then the operation can be repeated, and then the sound absorbing wedge plates can be quickly connected, thereby improving the connection efficiency.

Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
