[0054] A limit plate 1001 is fixedly installed at the middle of the bottom end of the main keel 1, a return spring 1002 is welded at the middle of the bottom end of the limit plate 1001, a vertical T-shaped plate 1003 is welded at the middle of the bottom end of the return spring 1002, a positioning spring 1005 is welded at the middle of the bottom end of the vertical T-shaped plate 1003, positioning springs 1005 are welded at the front and back of the bottom end of the limit plate 1001, and a horizontal T-shaped plate 1006 is welded at one end of the positioning spring 1005.

[0055] A connection mechanism 11 is fixedly installed on one side of the inner wall of the main keel 1, and the connection mechanism 11 includes a slave connection block 1101, a one-way threaded rod 1102, a threaded sleeve 1103, a positioning column 1104 and a slave moving block 1105;

[0056] A slave connecting block 1101 is fixedly installed on one side of the inner wall of the main keel 1, and a one-way threaded rod 1102 is welded to the middle of the front of the slave connecting block 1101, and a threaded sleeve 1103 is sleeved on the outer surface of the one-way threaded rod 1102.

[0057] The working principle and use process of the present invention: During the actual use of the keel with sound-absorbing effect, the user will install it between the slave keel 3 and the main keel 1, and then the user will pull the vertical plate 606. When the vertical plate 606 moves, it drives the connecting plate 602 to move. When the connecting plate 602 moves, it drives the main connecting block 603 and the T-shaped column 604 to move respectively. At this time, when the T-shaped column 604 moves, it drives the reset spring 605 to contract. Then the user rotates the vertical plate 606. The vertical plate 606 drives the connecting plate 602 to rotate. When the connecting plate 602 rotates, it drives the main connecting block 603 to rotate. Then the user releases the vertical plate 606. At this time, the T-shaped column 604 enters the interior of the limiting sleeve 601 due to the tension of the reset spring 605, and drives the connecting plate 602 to move. When the connecting plate 602 moves, it drives the main connecting block 603 to enter the interior of the limiting hole 5, thereby achieving the purpose of quickly installing the slave keel 3 and the main keel 1, and further saving the time required for installing the slave keel 3 and the main keel 1.

[0058] Next, the user connects the limit plate 1001 and the main keel 1, and then uses the user to horizontally squeeze the plate 1004 to contact the second main keel 1, and drives the horizontal squeezing plate 1004 to squeeze the return spring 1002, so that the return spring 1002 contracts and moves along the inside of the limit plate 1001, and at this time, the vertical L-shaped plate 1007 is in contact with the secondary keel 3, and the vertical L-shaped plate 1007 moves, and the vertical L-shaped plate 1007 moves, and the horizontal T-shaped plate 1006 moves when the vertical L-shaped plate 1007 moves, and the horizontal When the T-shaped plate 1006 moves, it squeezes the positioning spring 1005, and makes the positioning spring 1005 and the horizontal T-shaped plate 1006 enter the inside of the limit plate 1001. Finally, when the two sides of the main keel 1 are uneven, the user rotates the screw rod 1009 along the inside of the fixing rod 1008, and uses the screw rod 1009 to support the two sides of the main keel 1, which can prevent the main keel 1 and the secondary keel 3 from deforming, thereby making the main keel 1 and the secondary keel 3 more stable, thereby increasing the strength of the main keel 1 and the secondary keel 3 after installation;

[0059] Then, the user installs the curtain wall 7 between the secondary keel 3. First, the user rotates the two-way threaded rod 802. When the two-way threaded rod 802 rotates, it drives the main moving block 803 to move. When the main moving block 803 moves, it drives the inclined plate 804 to move. Then, the rotating adsorption block 806 is rotated along the rotating groove 805 so that one end face of the rotating adsorption block 806 is perpendicular to the plane. Then, the curtain wall 7 is placed into the secondary keel 3 so that the curtain wall 7 enters the inner wall of the vertical L-shaped plate 1007 and the rotating adsorption blocks 806 are fitted to each other. Then, the user rotates the bolt to preliminarily fix the curtain wall 7 and the secondary keel 3. Then, the user rotates the screw 807 to connect and fix the curtain wall 7 and the rotating adsorption block 806, which increases the efficiency of the personnel in installing the curtain wall 7 and can perform secondary fixation on the installed curtain wall 7, thereby making the installed curtain wall 7 more stable.

[0060] Then the user splices the two main keels 1. At this time, the user rotates the threaded sleeve 1103, and the threaded sleeve 1103 rotates along the outer surface of the one-way threaded rod 1102. When the threaded sleeve 1103 rotates, it moves along the direction of the thread of the one-way threaded rod 1102. When the threaded sleeve 1103 moves, it drives the positioning column 1104 to move. When the positioning column 1104 moves, it drives the slave moving block 1105 to move, so that the slave moving block 1105 enters the inside of another main keel 1, thereby increasing the efficiency of splicing the main keels 1 and reducing the time required for splicing the main keels 1.

[0061] Finally, the main keel 1 and the wall are connected by the wall connector 2. When the wall shakes, the rectangular bar 909 is driven to move. When the rectangular bar 909 moves, the shock-absorbing spring 907 and the manual telescopic rod 906 are contracted, and the rubber pad 908 and the shock-absorbing pad 905 are brought into contact. At this time, the impact force caused by the contact between the fixed bar 901 and the rectangular bar 909 is initially buffered by the rubber pad 908 and the shock-absorbing pad 905. At this time, the noise generated by the impact of the fixed bar 901 and the rectangular bar 909 is guided to the inside of the sound-absorbing sponge 904 through the conical head 903 in turn, so that the noise is absorbed by the sound-absorbing sponge 904, and the external noise is directly absorbed by the sound-absorbing sponge 904, thereby reducing the interference of noise.
