Treadmill capable of automatically tensioning running belt

Abstract

The invention discloses a treadmill capable of automatically tensioning a running belt. The treadmill comprises a treadmill platform, a running plate, a front roller, a rear roller and a running belt.U-shaped spring fixing bases are fixedly mounted on the two sides of the rear end surface of the running plate. End parts are arranged on the two sides of the rear roller. An end portion is providedwith fixing holes. Round-head hexagon socket screws are mounted on the U-shaped spring fixing bases. The round-head hexagon socket screws are inserted from the rear sides of the U-shaped spring fixing bases, penetrate through fixing holes in the ends of the rear roller and the front sides of the U-shaped spring fixing bases and are connected to the rear end face of the running plate. Springs arearranged between the ends of the two sides of the rear roller and the inner surfaces of the front sides of the U-shaped spring fixing bases. The springs are arranged on the round-head hexagon socket screws in a sleeving mode. The automatic tensioning can be achieved. The tensioning degree of the running belt does not need to be manually adjusted. The normal service life of the treadmill is prolonged. The treadmill is scientific and reasonable in structure, and safe and convenient to use. The practical performance of the treadmill is improved, and the treadmill is more suitable for running activities of people in daily life.

Description

technical field [0001] The invention relates to the technical field of treadmills, in particular to a treadmill capable of automatically tensioning a running belt. Background technique [0002] With the improvement of living standards, exercise has become an activity that people pay special attention to. Treadmills are regular fitness equipment for families and gyms, and are the simplest type of home fitness equipment today. They are the best choice for home fitness equipment. [0003] However, after the treadmills on the market are used for a period of time, the running belt will become slack, and it is necessary to manually adjust the tightness of the running belt. Manual adjustment is not only time-consuming and laborious, but also the running belt is in a loose state for a long time, which will seriously shorten the normal service life of the treadmill. , causing certain economic losses, for this reason, we propose a treadmill that can automatically tension the running b...
