Environment-friendly acoustic panel for building

An environment-friendly acoustic panel for building, comprising:

• an acoustic panel body, which comprises a first positioning groove formed by recessing of one vertical edge of the acoustic panel body and a second positioning groove formed by recessing of the other vertical edge of the acoustic panel body, wherein the first positioning groove is arranged in a vertical length direction of the acoustic panel body and a length of the first positioning groove is equal to a vertical length of the acoustic panel body, a horizontal cross section of the first positioning groove is a semi-circular arc, a positioning cylinder with open top and bottom ends is fixedly arranged in the first positioning groove in a length direction of the first positioning groove, a length of the positioning cylinder is equal to that of the first positioning groove, the positioning cylinder is provided with an opening in an outer side wall of the first positioning groove, the opening is arranged in a length direction of the positioning cylinder and a length of the opening is equal to that of the positioning cylinder, the second positioning groove is arranged in a vertical length of the acoustic panel body and a length of the second positioning groove is equal to the vertical length of the acoustic panel body, a horizontal cross section of the second positioning groove is a semi-circular arc, a fixing block is arranged in the second positioning groove, the fixing block comprises a vertical portion arranged in a length direction of the second positioning groove and an arc-shaped portion integrally formed with the vertical portion, a horizontal cross section of the arc-shaped portion is a major arc and a diameter of the major arc is larger than a width of the vertical portion, wherein the width of the vertical portion is slightly smaller than a width of the opening;
• and
• two sets of sealing assemblies, wherein the two sets of sealing assemblies are respectively arranged in one-to-one correspondence with two vertical edges of the opening, the sealing assembly comprises an accommodating groove formed by outwardly recessing of the vertical edge of the opening, a length of the accommodating groove is slightly smaller than the length of the opening, a bottom portion of the accommodating groove is provided with a plurality of springs at intervals up and down, end portions of the plurality of springs are jointly connected with a positioning plate, a length of the positioning plate is slightly smaller than that of the accommodating groove, the positioning plate is slidably connected with a side wall of the accommodating groove, a surface of the positioning plate facing away from the springs is fixedly provided with a sealing block, and the sealing block is hermetically and slidably connected with the side wall of the accommodating groove, wherein two steel wire ropes are connected onto a surface of the positioning plate connected with the springs, the two steel wire ropes are respectively located at an upper portion and a lower portion of the positioning plate, the steel wire rope located at the upper portion slides through a top end of the positioning cylinder, while the steel wire rope located at the lower portion slides through a bottom end of the positioning cylinder;
• wherein, when two acoustic panel bodies are connected, the arc-shaped portion of one acoustic panel body is located in the positioning cylinder of the other acoustic panel body, two sealing blocks corresponding to the positioning cylinder abut against the vertical portion, top ends and bottom ends of the two acoustic panel bodies are flush, and surfaces of the two acoustic panel bodies are flush.
