Description

Technical Field

[0001] This utility model relates to a walking belt tension testing device, specifically an airbag-type walking belt pressure testing device. Background Technology

[0002] Treadmills are commonly used fitness equipment. They mainly consist of a running platform, drive system, shock absorption system, safety devices, and control panel. The running platform itself is composed of a walking belt, pedals, and rollers.

[0003] The tightness of the running belt is a very important indicator. If the running belt is too tight, it will increase the resistance when running, causing the user to need more force to push the belt, thereby increasing the exercise burden, reducing comfort, accelerating the wear of the running belt, and shortening its lifespan. At the same time, an overly tight running belt may also cause the edges of the running belt to crack or break. If the running belt is too loose, the user may feel slippery or unstable when running, especially during fast running or high-intensity training, which increases the risk of falling.

[0004] Therefore, adjusting the tension of the walking belt is an important step when the product leaves the factory. Traditional tension testing instruments test the tension by measuring the frequency of the vibration of the object. However, finished treadmills have a foot pedal under the walking belt. When the tension of the walking belt is tested, it will be blocked by the foot pedal, making it impossible to measure the tension based on the vibration frequency. Therefore, an alternative method is needed to test the tension of the walking belt. Utility Model Content

[0012] The beneficial effects of this utility model are:

[0013] 1. By setting an airbag inside the fixed box and installing an inflation ball and an airbag pressure gauge on the airbag, the tension of the walking belt can be calculated by first inflating the airbag, then placing the fixed box between the walking belt and the pedal. At this time, the airbag will be compressed by the walking belt. The pressure on the airbag can then be read from the airbag pressure gauge.

[0014] 2. By setting a pad slot at the bottom of the fixed box and installing a replaceable pad in the pad slot, the height of the fixed box can be set to accommodate different spacing between the walking belt and the pedal of different treadmill models.

[0015] 3. By setting up a lifting base and adjusting the height of the fixed box through the meshing of gears and racks, the height can be adjusted by rotating the gears to accommodate different spacing between the walking belt and pedals of different treadmill models. Attached Figure Description
