When the belt tensioner tension adjustment structure needs to be fine-tuned, the knob is turned, and the knob drives the rotating disk to rotate, and the moving column on the rotating disk also starts to rotate. When the moving column rotates, it drives the long rod to move, causing the front end position of the long rod to move. The long rod is connected to the moving column through a hole, and the moving column at the front end is connected to the moving block. The long rod drives the moving block to move along the moving groove, and the moving block drives the adjusting wheel to move. Since the adjusting wheel is in contact with the belt, the moving adjusting wheel can achieve the purpose of fine-tuning, and achieves subtle tension adjustment, so that the tension of the belt can accurately adapt to the work requirements.

[0025] Example

The overall idea is as follows:

[0027] In view of the problems existing in the prior art, the utility model provides a belt tensioning wheel tension adjustment structure, including a device body 11, an adjusting wheel 12 is arranged at the upper end of the device body 11, and the belt tensioning wheel tension adjustment structure is also provided with a fine adjustment mechanism, including a rotating disk 14, a long rod 19 and a moving block 21, the device body 11 is rotatably connected to the rotating disk 14, the long rod 19 is located at the lower end of the device body 11, both ends of the long rod 19 are penetrated and opened with holes 25, and the long rod 19 is rotatably connected to the moving column 21 through the two holes 25. 18, the moving column 18 at the rear end position is rotatably connected to the lower surface of the rotating disk 14, and the upper surface of the moving column 18 at the front end position is rotatably connected to the moving block 21. The upper surface of the device body 11 is penetrated with a moving groove 20, and the moving block 21 is located inside the moving groove 20. The upper surface of the moving block 21 is fixedly connected to the lower surface of the adjusting wheel 12. When the belt tensioning wheel tension adjustment structure needs to be fine-tuned, the knob 13 is turned, and the knob 13 drives the rotating disk 14 to rotate, and the moving column 18 on the rotating disk 14 also starts to rotate. When the moving column 18 rotates, it will drive the long rod 19 to move, causing the front end position of the long rod 19 to move. The long rod 19 is connected to the moving column 18 through the hole 25, and the moving column 18 at the front end is connected to the moving block 21, and the long rod 19 will drive the moving block 21 to move along the moving groove 20.

[0028] Both ends of the moving block 21 are fixedly connected to the limiting blocks 22. The inner wall of the device body 11 is provided with two limiting grooves 23. The two limiting grooves 23 are parallel to each other and correspond to the positions of the two limiting blocks 22. The two limiting blocks 22 are movably connected to the device body 11 through the corresponding limiting grooves 23. The upper surface of the rotating disk 14 is fixedly connected with the fixing column 16, and the upper surface of the fixing column 16 is fixedly connected with the knob 13. The moving block 21 will drive the adjusting wheel 12 to move. Since the adjusting wheel 12 is in contact with the belt, the moving adjusting wheel 12 can achieve the purpose of fine-tuning, thereby realizing a subtle tension adjustment, so that the tension of the belt can accurately adapt to the working requirements.

During the movement process, the moving block 21 will also move with the limit block 22, and the limit block 22 moves in the limit groove 23, which makes the moving block 21 more stable when driving the adjusting wheel 12.
