The anti-deviation component includes: a fixing groove 3, which is formed on both sides inside the support frame 1; a support groove 4 formed on one side inside the fixing groove 3; a movable plate 5 disposed on one side inside the fixing groove 3; two limiting holes 7 formed on one side of the movable plate 5; limiting posts 6 movably sleeved on the inner circular wall of the limiting holes 7; the limiting posts 6 being fixedly installed on one side inside the fixing groove 3; a connecting foot 13 fixedly installed on one side of the movable plate 5; a second connecting plate 14 rotatably connected inside the connecting foot 13; two rotating arms 19 disposed inside the support frame 1; a double-ear push rod 18 rotatably connected to one end of each rotating arm 19; and a U-shaped frame fixedly installed inside the support frame 1. 17. The earring of the double-ear push rod 18 is rotatably connected to the U-shaped frame 17. Limiting frames 10 are fixedly installed on both sides of the inside of the support frame 1. The limiting frames 10 are movably sleeved with the rotating arm 19. The outside of the rotating arm 19 is rotatably connected to the first connecting plate 12. One end of the first connecting plate 12 is provided with a limiting groove 16. The limiting groove 16 is movably sleeved with the second connecting plate 14. One side of the first connecting plate 12 is provided with a first circular through hole. The inner circular wall of the first circular through hole is fixedly sleeved with a pressure sensor 15. The pressure sensor 15 is a push-pull sensor, model Zhongwan Jinno-JLBT-M2. One end of the pressure sensor 15 is fixedly installed with the second connecting plate 14. The inside of the moving plate 5 is rotatably connected to the connecting frame 9. The inside of the running belt 2 is provided with a rear support roller 8. The rear support roller 8 is fixedly installed with the connecting frame 9. The outer circular wall of the rear support roller 8 is movably sleeved with a rear roller 11.

[0030] In use, when the pressure sensors 15 on the left and right sides detect an imbalance in data for an extended period, the running belt 2 may be biased towards one end of the rear roller 11. To center the running belt 2 on the rear roller 11, one end of the rear roller 11 needs to be loosened. At this time, the double-ear push rods 18 on the left or right side are activated to push (pull) the rotating arm 19 to rotate under the support of the limit frame 10. The rotating arm 19 pushes (pulls) the first connecting plate 12 through the lever principle, which drives the pressure sensor 15 to push the second connecting plate 14, thereby driving the moving plate 5 to move. The moving plate 5 drives the connecting frame 9 to move back and forth, thereby adjusting the tension of one end of the rear roller 11. When the pressure sensor 15 detects that the squeezing pressure on both sides is balanced, the adjustment stops.

[0031] In this embodiment, a rectangular groove is provided on the top surface of the support frame 1. A front support roller 24 is provided inside the rectangular groove. A front roller 23 is movably sleeved on the outer circular wall of the front support roller 24. The front roller 23 is movably sleeved with the running belt 2. A threaded groove 27 is provided on the bottom surface of the rectangular groove. A threaded hole is provided on the top surface of the front support roller 24. A bolt 25 is threadedly connected to the inner circular wall of the threaded hole. The bolt 25 is threadedly connected to the threaded groove 27. Two limiting plates 26 are fixedly installed on the bottom surface of the rectangular groove. Fixing frames 20 are fixedly installed on both sides of the inside of the support frame 1. A fixing plate 21 is fixedly installed on the top surface of the fixing frame 20. A housing 22 is fixedly installed on the top surface of the support frame 1. The housing 22 is fixedly installed on one side of the support frame 1. An arc-shaped chamfer is provided on one side of the moving plate 5. A PLC controller is fixedly installed on one side of the support frame 1. The PLC controller is electrically connected to the pressure sensor 15 and the double-ear push rod 18.

[0032] In use, the curved chamfer on one side of the moving plate 5 allows the rear roller 11 to rotate slightly under the support of the connecting frame 9 and the rear support roller 8, thus avoiding contact and friction with the moving plate 5.

[0033] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0034] With the support frame 1 in place, when the user needs to use the support frame 1, the running belt 2 rotates. When the running belt 2 rotates, the rear roller 11 is pushed by force against the rear support roller 8. The rear support roller 8 drives the moving plate 5 to move back and forth under the support of the two limit posts 6. The moving plate 5 drives the connecting foot 13 to push the second connecting plate 14 to apply pressure to the pressure sensor 15. The pressure sensor 15 detects the magnitude of the force, and thus detects the tension of the running belt 2. When the pressure sensors 15 on the left and right sides detect that the data is unbalanced for a long time, the running belt 2 may be biased towards one end of the rear roller 11. In order to center the running belt 2 on the rear roller 11, one end of the rear roller 11 needs to be loosened. At this time, the double-ear push rod 18 on the left or right side is activated to push (pull) the rotating arm 19 to rotate under the support of the limit frame 10. The rotating arm 19 pushes (pulls) the first connecting plate 12 through the lever principle, which in turn drives the pressure sensor. The device 15 pushes the second connecting plate 14, which in turn drives the moving plate 5 to move. The moving plate 5 drives the connecting frame 9 to move back and forth, thereby adjusting the tension of one end of the rear roller 11. When the pressure sensor 15 detects that the pressure on both sides is balanced, the adjustment stops. At the same time, if there is a data deviation between the two sensors but the running belt 2 is normally centered, the data difference can be manually cleared to make the data equal. Based on the default data deviation of the pressure sensor 15, such as a data deviation of 5 kg, the adjustment is automatic, thus achieving the effect of preventing the running belt 2 from shifting. By pushing and pulling the rotating arm 19 through the set double-ear push rod 18, the moving plate 5 is moved back and forth using the lever principle, adjusting the position of both ends of the rear roller 11. In conjunction with the pressure sensor 15, the tension of the running belt 2 is dynamically adjusted, effectively avoiding the shift of the running belt 2 due to insufficient support of the rear roller 11. At the same time, no manual operation is required, which is convenient for ordinary users and quite practical.
