Description

Technical Field

[0001] The present application relates to the technical field of treadmill maintenance equipment, and in particular to a treadmill belt deviation correction device. Background Art

[0002] The statements in this section merely provide background technical information related to this application and do not necessarily constitute prior art.

[0003] Treadmill belts are not made of rigid material. After a period of use, they tend to loosen, meaning their circumference increases. This can lead to belt deviation, which can cause significant inconvenience for treadmill users and pose a safety risk.

[0004] In the prior art, most measures to correct treadmill deviation are to adjust the rollers at both ends of the running belt, that is, to adjust the two ends of the rollers separately to extend the distance between the two rollers. However, this adjustment method easily causes the axis of the adjusted roller to shift, making the central axes of the two rollers non-parallel, which in turn makes the running belt more likely to deviate.

[0005] In view of this, it is necessary to provide a treadmill belt correction device to solve the above technical problems. Summary of the Invention

[0006] Based on this, in order to solve the above technical problems, the present application provides a treadmill belt correction device.

[0044] The control device controls the alarm module to issue an alarm. In some embodiments, the alarm module is a speaker and the control device is an MCU.

[0045] Rotate the turntable 22 so that the pressing tool 24 does not apply pressure to the adjusting rod 13;

[0046] Turning the adjusting nut 12 moves the adjusting rod 13, applying pressure to the movable frame 8, thereby moving the slider 19, thereby increasing the distance between the center axes of the two rotating rollers 2 and adjusting the distance between the two rotating rollers 2 in parallel; tightening the running belt to prevent deviation.

[0047] When the alarm module does not issue an alarm prompt, stop rotating the adjusting nut 12; then rotate the turntable 22 to make the pressing tool 24 press the adjusting rod.

[0048] The treadmill belt deviation correction device of the present application can prevent the belt from deviating in advance. When the belt becomes loose, it can promptly issue a warning sound prompt. The warning sound prompt will not stop until the belt is tightened, that is, the distance between the two rotating rollers is readjusted. The distance between the two rotating rollers is adjusted in parallel, rather than adjusting the two ends of one of the rotating rollers separately, so the adjustment effect is good.

Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
