An electric treadmill

Abstract

An electric treadmill comprises a base, an armrest, a run belt, a protective pad, and a reduction belt; the run belt sleeves a driving roller and a driven roller to form a belt drive mechanism; two reduction wheels are disposed at two axial ends of the driven roller respectively; stoppers on the reduction wheels are used with anti-skid cylinders to limit the speed of the tread mill. Falling injury is reduced by the use of a protective pad arranged below the armrest; pain is eased by buffering of the protective pad when a user falls onto the protective pad; the reduction belt is disposed at the rear of the treadmill, the user can step into the reduction belt in time to retard backward skid of the body before the user falls, friction of the human body with equipment and ground is reduced, and bruises are avoided. Meanwhile, the stoppers and the anti-skid cylinders are disposed on the driven roller, the stoppers are retracted into the reduction wheels through springs, centrifugal force that the stoppers experience is larger than pretension force of the springs when the speed is too high, the springs can pop out and enter the anti-skid cylinders exactly so that the speed is reduced, and accidents caused by the excessively high speed are avoided.

Description

technical field [0001] The invention relates to an auxiliary equipment for physical exercise, in particular to an electric treadmill. Background technique [0002] Treadmill is a kind of commonly used fitness equipment, which can be used to warm up the human body and also allow users to exercise. Without safety guidance, exercisers often encounter exercisers who accidentally fall down and easily injure their arms. At the same time, they will row backward along the treadmill. At the same time, sometimes the treadmill will overspeed and cause accidents. Contents of the invention [0003] The purpose of the present invention is to provide an electric treadmill to solve the problems that existing treadmills are easy to overspeed and cause accidents and injuries after falling. The cushioning on the protective pad relieves pain, and at the same time, there is a speed bump behind the treadmill. If you fall down, you can step into the speed bump in time to slow down the human bod...

Problems solved by technology

[0003] The purpose of the present invention is to provide an electric treadmill to solve the problems that existing treadmills are easy to overspeed and cause accidents and injuries after falling. The cushioning on the protective pad relieves pain, and at the same time, there is a speed bump behind the treadmill. If you fall down, you can step into the speed bump in time to slow down the human body sliding backwards, reducing the friction between the human body and the equipment and the ground, thereby avoiding scratches. At the same time, a stopper and an anti-skid cylinder are arranged on the driven roller, and the stopper is shrunk in the reduction wheel through the spring. When the speed is too fast, the centrifugal force received by the stopper is greater than the pre-tightening force of the spring, and the spring will pop out and be inserted. The anti-skid tube slows down the speed and avoids accidents caused by excessive speed
