[0027] See also Figure 1-5 A rocker arm assembly for a large square rocking screen comprises a square rocking screen 1, a support frame 2 and a rocker arm assembly, wherein a rocker arm assembly is arranged outside the square rocking screen 1 and inside the support frame 2;

[0028] The rocker arm assembly includes four rocker arms 4, both ends of which are rotatably connected to a connecting seat 5 via a rotating shaft 8. The connecting seat 5 located at the top of the rocker arm 4 is bolted to the support frame 2 via a fixing seat 6. The connecting seat 5 located at the bottom of the rocker arm 4 is fixed to the connecting block 7 by welding, and the connecting block 7 is bolted to the square rocking screen 1.

[0029] In this embodiment, raised blocks 3 are provided on both sides of the square rocking screen 1. The raised blocks 3 are inclined at an angle of 45 degrees and protrude outwards. The connecting blocks 7 are fixedly connected to the square rocking screen 1 through bolts.

[0030] It should be noted that the design of the raised blocks 3 on both sides of the square swing screen 1 not only enhances the structural strength of the screen body, but also provides a stable connection point for the connecting block 7. The connecting block 7 is fixedly connected to the square swing screen 1 through the raised blocks 3, and this connection method is both firm and easy to install and maintain.

[0031] In this embodiment, the connecting block 7 is formed by a first connecting block 701 and a second connecting block 702 fixedly connected. The first connecting block 701 is plugged into the protruding block 3 and after the plugging, the insert rod 10 and the screw rod 11 are fixedly connected in sequence in two mutually perpendicular directions of the vertical horizontal plane.

[0032] It should be noted that the connecting block 7 is formed by a first connecting block 701 and a second connecting block 702 that are fixedly connected. This combined design makes the structure of the connecting block 7 more stable and able to withstand greater force. The plug-in design of the first connecting block 701 and the protruding block 3 makes the connection process simple and quick. At the same time, the fixing method of the plug rod 10 and the screw rod 11 also enhances the stability of the connection.

[0033] In this embodiment, a second through hole 704 is provided in the middle of the second connecting block 702, and second through holes 704 are distributed inside the second connecting block 702 and along the circumference of the center of the second through hole 704. The connecting seat 5 is formed by a rotating block 501, a stopper 502 and a plug-in column 503 that are fixedly connected in sequence, and a first through hole 505 distributed circumferentially is provided inside the stopper 502.

[0034] It should be noted that the plurality of circumferentially distributed first through holes 505 are used for preliminary fixation after being plugged into the plug posts 602 .

[0035] In this embodiment, the plug-in column 503 of the connecting seat 5 located at the bottom end of the rocker arm 4 is plugged into the second through hole 704, and is fixedly connected with the fixing seat 6 after plugging. The connection between the connecting seat 5 located at the top end of the rocker arm 4 and the support frame 2 is also fixedly connected by bolts through the fixing seat 6.

[0036] In this embodiment, a plug-in hole 601 is opened in the middle of the fixing seat 6, and a plug-in column 602 is provided at one end of the fixing seat 6 facing the connecting seat 5. The plug-in column 503 is plugged into the plug-in hole 601, the bottom plug-in column 602 is plugged into the first through hole 505 and the second through hole 704, and the top plug-in column 602 is plugged into the support frame 2 and the first through hole 505. After the top and bottom plug-in columns 602 are plugged in, they are fixedly connected with locking blocks 9.

[0037] It should be noted that the fixing seat 6 plays a key fixing role in the entire assembly. The plug-in through hole 601 opened in the middle is used to plug with the plug-in column 503 of the connecting seat 5, and the plug-in column 602 facing one end of the connecting seat 5 is plugged with the first through hole 505 and the second through hole 704 to achieve a fixed connection between the connecting seat 5 and the second connecting block 702 and the support frame 2. After plugging, the plug-in columns 602 at the top and bottom are fixed by the locking block 9 to ensure the stability of the connection.

[0038] In this embodiment, rotating through holes 504 are opened on both sides of the rotating block 501 , and a rotating shaft 8 is fixedly connected inside the rotating through hole 504 and is rotatably connected to the rocker arm 4 through the rotating shaft 8 .

[0039] It should be noted that the rotating shaft 8 fixedly connected inside the rotating through holes 504 on both sides of the rotating block 501 enables the rocker arm 4 to rotate around the rotating shaft 8. This rotating connection mode is not only flexible, but also can ensure the stability of the rocker arm 4 during the rotation process.

[0040] Working principle:

[0041] The rocker arm assembly is composed of four rocker arms 4, and both ends of each rocker arm 4 are rotatably connected through a connecting seat 5. The connecting seat 5 located at the top of the rocker arm 4 is fixedly connected to the support frame 2 through a fixing seat 6 to ensure that the rocker arm 4 has a stable support point at the top. The connecting seat 5 located at the bottom of the rocker arm 4 is fixedly connected to the connecting block 7, and the connecting block 7 is further fixedly connected to the raised block 3 of the square rocking screen 1. The design of the raised block 3 tilted at a 45-degree angle not only enhances the stability of the connection, but also helps to evenly force the square rocking screen 1. At the same time, the first connecting block 701 is plugged into the side of the square rocking screen 1 through the raised block 3, and is fixed by the plug rod 10 and the screw 11 to ensure the firmness of the connection. The cylindrical through hole 703 opened in the middle of the second connecting block 702 is plugged into the plug-in column 503 of the connecting seat 5 at the bottom of the rocker arm 4 to achieve a fixed connection between the rocker arm 4 and the connecting block 7.

[0042] Beneficial effects:

[0043] The rocker arm assembly for the large square rocking screen realizes a fixed connection between the rocker arm 4 through the connecting seat 5, the support frame 2 and the connecting block 7. This connection method enables the entire rocker arm assembly to remain stable during operation and is not easy to loosen or fall off. The setting of the fixed seat 6 further enhances the stability and reliability of the connection through the plug-in connection of the plug column 602 with the plug-in through hole 601, the first through hole 505 and the second through hole 704, and the fixation of the locking block 9. Simple connection methods such as plug-in and threaded connection make the installation process simple and quick, reducing the installation cost and time. The connection between the components is clear, which makes the subsequent maintenance work relatively easy and reduces the difficulty and cost of maintenance.
