Description

TECHNICAL FIELD

[0001] The utility model relates to an indoor fitness bicycle pedal anti-belt sagging structure. BACKGROUND

[0002] With the acceleration of the pace of life, people's physical quality is greatly reduced, and the consciousness of exercising the body is gradually improved, so people often choose to go to the gym or purchase fitness equipment at home for fitness, and fitness bicycles or spinning bicycles are popular among fitness enthusiasts, and fitness people consume excess energy in the body by pedaling fitness bicycle pedals to drive wheel rotation to achieve the purpose of weight loss and fitness. When using the fitness bicycle, the foot is stepped on the pedal, and the shoe needs to be tightly bound on the pedal with a belt to prevent the foot from separating from the pedal. The belt is usually installed by sequentially threading one end of the belt through the shoe kit and the pedal, and then buckling or bonding the other end of the belt. The adjustment part left over after the two ends of the belt are connected is located inside the pedal at this time. Because the belt is made of soft cloth, in order to ensure that the belt can pass through the hole of the pedal, the hole on the traditional pedal is usually composed of two disconnected holes. However, this structure has a safety hazard, that is, when pedaling, the position where the belt connects will move constantly until it moves between the two disconnected holes on the pedal. Due to the action of gravity, part of the belt will slowly sag from the gap between the two holes. The sagging belt may hook the protruding part below the pedal when pedaling, causing the pedal to stop pedaling. The user is suddenly interrupted and cannot maintain the balance of the body, which may cause the user to fall or sprain the ankle, causing personal accidents.

[0003] In view of this, the present inventors have conducted in-depth research on the above problems, and thus the present case has been produced. CONTENT OF THE UTILITY MODEL
