[0006] Further, the connecting plate and the clamping block are equipped with the buffer spring of damper.

[0007] Further, the drum body includes the inner tube connected with the center shaft, and the outer tube connected with the inner tube, and the sound insulation cotton is placed between the inner tube and the outer tube.

[0008] Further, the support block is equipped with a bearing matched with the center shaft.

[0009] Further, the other end of the screw rod is provided with a handle placed outside the sleeve, and the connecting plate is symmetrically provided with a limiting rod placed outside the sleeve.

[0010] Further, the mounting plate is provided with a plurality of mounting holes around the edge, and the mounting plate is fixed on the treadmill support through bolts penetrating the mounting holes.

[0011] The utility model discloses beneficial effect:

[0012] The sound insulation cotton arranged in the roller body can play a sound insulation and noise reduction role, the support block can be clamped and fixed between the clamping blocks through the locking assembly, and the roller body inevitably vibrates during rotation, thereby causing the central shaft and the support block to vibrate, and under the action of the buffer spring equipped with the damper, vibration and energy can be reduced, thereby effectively reducing noise generated by vibration and greatly improving the noise reduction effect.
