A toothed seat 2 is fixedly connected to the side of the pulley body 1. A rotating plate 4 is rotatably connected to the surface of the pulley body 1. An installation rod 7 is slidably connected to the inner wall of the rotating plate 4. A vertical plate 9 is fixedly connected to the end of the installation rod 7 near the toothed seat 2, and a limiting plate 8 is fixedly connected to the end of the installation rod 7 away from the vertical plate 9. An arc-shaped rubber pad 10 is glued to the side of the vertical plate 9 near the pulley body 1. By setting the rotating plate 4 and the installation rod 7, the vertical plate 9 and the arc-shaped rubber pad 10 can be easily installed onto the pulley body 1. By setting the arc-shaped rubber pad 10, the belt can be tightened, making it convenient for workers to install the pulley body 1.

[0029] The following is a detailed explanation of its overall setup and function.

[0030] Reference Figures 1-4 As shown in this embodiment: a baffle 5 is fixedly connected to the surface of the pulley body 1, and a spring 6 is fixedly connected to the side of the rotating plate 4 away from the baffle 5. The other end of the spring 6 is fixedly connected to the pulley body 1. By setting the baffle 5, the rotation of the rotating plate 4 can be restricted. By setting the spring 6, the position of the rotating plate 4 can be restricted. A rotating rod 12 is rotatably connected to the inner wall of the rotating plate 4. A pressure plate 11 is fixedly connected to the end of the rotating rod 12 near the mounting rod 7. By setting the rotating rod 12, the pressure plate 11 can be connected to the rotating plate 4, while ensuring that the pressure plate 11 can rotate. By setting the pressure plate 11, the position of the mounting rod 7 can be restricted. A torsion spring 13 is sleeved on the surface of the rotating rod 12. The two ends of the torsion spring 13 are fixedly connected to the pressure plate 11 and the rotating plate 4, respectively. By setting the rotating rod 12, the position of the torsion spring 13 can be restricted. By setting the torsion spring 13, the pressure plate 11 can be reset after rotation.

[0031] A positioning plate 14 is fixedly connected to the side of the pulley body 1 away from the rotating plate 4. A first clamping plate 15 is installed on the side of the pulley body 1 close to the positioning plate 14, and a second clamping plate 16 is installed on the side of the pulley body 1 away from the first clamping plate 15. By setting the positioning plate 14, the first clamping plate 15 and the second clamping plate 16 can be positioned when installed on the pulley body 1. A connecting rod 17 is fixedly connected to the side of the first clamping plate 15 and the second clamping plate 16 away from each other. A stop plate 18 is fixedly connected to the end of the connecting rod 17 away from the pulley body 1. By setting the connecting rod 17, the stop plate 18 can be connected to the first clamping plate 15 and the second clamping plate 16. By setting the stop plate 18, the position of the belt can be restricted. An adjusting screw 19 is rotatably connected to the side of the first clamping plate 15 near the second clamping plate 16. The adjusting screw 19 is threaded into the inner wall of the second clamping plate 16. A stabilizing rod 20 is slidably connected to the inner wall of the second clamping plate 16. The stabilizing rod 20 is fixedly connected to the side of the first clamping plate 15 near the second clamping plate 16. A rubber pad 21 is glued to the side of the second clamping plate 16 near the pulley body 1. By setting the adjusting screw 19, the distance between the first clamping plate 15 and the second clamping plate 16 can be adjusted. By setting the rubber pad 21, the stability of the connection between the first clamping plate 15, the second clamping plate 16 and the pulley body 1 can be improved.

[0032] Working principle: When the pulley body 1 needs to be installed, first move the pulley body 1 to the installation position, put the belt on the surface of the gear seat 2, move the first clamping plate 15 through the through hole 3, then move the first clamping plate 15 closer to the positioning plate 14, and then rotate the adjusting screw 19 to make it rotate on the surface of the first clamping plate 15 and the inner wall of the second clamping plate 16. At this time, under the restriction of the stabilizing rod 20, the second clamping plate 16 drives the rubber pad 21 closer to the pulley body 1, thereby installing the first clamping plate 15 and the second clamping plate 16 on the pulley body 1. The stop plate 18 restricts the position of the belt. Then, rotating the rotating plate 4 closer to the baffle 5, rotating the pressure plate 11 away from the spring 6, and moving the mounting rod 7 closer to the rotating plate 4, releasing the pressure plate 11, allows the pressure plate 11 to rotate under the force of the torsion spring 13, causing the pressure plate 11 to rotate and move closer to the mounting rod 7, thus restricting the position of the mounting rod 7. At this time, the vertical plate 9 and the arc-shaped rubber pad 10 clamp the belt, completing the belt fixation. Then, the pulley body 1 is installed. After the pulley body 1 is installed, rotating the pressure plate 11 away from the mounting rod 7... Move the installation rod 7 away from the rotating plate 4, release the pressure plate 11 and the rotating plate 4. Under the action of the torsion spring 13, the pressure plate 11 returns to its original position. At the same time, under the action of the spring 6, the rotating plate 4 rotates away from the baffle 5. Then rotate the adjusting screw 19 to move the second clamping plate 16 away from the first clamping plate 15. Move the first clamping plate 15 and the second clamping plate 16 away from the pulley body 1, thus completing the installation of the pulley body 1. By setting the connecting rod 17, the abutment plate 18 can be connected to the first clamping plate 15 and the second clamping plate 16. By setting the limiting plate 8, it is possible to... To ensure the stability of the installation of the mounting rod 7, the rotating plate 4, baffle 5, mounting rod 7, vertical plate 9, and arc-shaped rubber pad 10 are set up to clamp the belt on the surface of the pulley body 1 during the installation process. This ensures that the belt fits the pulley body 1 as closely as possible during installation. The first clamping plate 15, second clamping plate 16, and abutment plate 18 are set up to minimize the belt misalignment during installation, thus facilitating the installation of the pulley body 1.
