Pedal anti-separation structure of exercise bicycle

Abstract

The invention discloses a pedal anti-disengaging structure of an exercise bicycle. The structure comprises a bicycle body, a connecting rod is fixedly connected to the transmission end of the bicycle body, a shaft rod is movably connected to the outer side of the connecting rod through a pin shaft, the surface of the shaft rod is sleeved with a pedal, a storage groove is formed in the outer side of the pedal, and a bolt is arranged on the outer side of the shaft rod. Openings communicating with the storage groove are formed in the left side and the right side of the surface of the shaft rod correspondingly, clamping blocks are movably connected to the left side and the right side of the inner wall of the shaft rod through pin shafts correspondingly, the outer sides of the clamping blocks penetrate through the openings and extend into the storage groove, and extrusion blocks located on the outer sides of the clamping blocks are movably connected into the shaft rod. An existing installation mode that the pedal makes direct contact with the threaded assembly is replaced, and the problems that in the cyclic rotating process of an existing pedal, torsion is easily transmitted into the threaded assembly, the threaded assembly is prone to loosening after long-time use, and consequently the pedal is disengaged are solved.

Description

technical field [0001] The invention relates to the technical field of fitness equipment, in particular to a pedal detachment prevention structure of an exercise bike. Background technique [0002] Exercise bikes are called power bikes in the field of sports science. They are divided into two types: upright exercise bikes and backrest exercise bikes. They can adjust the intensity of exercise and have a fitness effect, so people call it exercise bikes, which are typical simulated outdoor bikes. Aerobic fitness equipment for sports is also called cardiopulmonary training equipment. It mainly promotes cardiovascular exercise, speeds up metabolism, and enhances heart and lung functions through long-term, moderate-intensity exercise of the body, thereby improving the body's physical fitness. [0003] Exercise bikes are generally used for circular motion by stepping on the pedals, but the existing pedals tend to transmit torque to the inside of the threaded components during the c...

Problems solved by technology

[0004] In order to solve the problems raised in the above-mentioned background technology, the purpose of the present invention is to provide a pedal detachment prevention structure of an exercise bike, which has the advantage of preventing the detachment of the pedals, and solves the problem that the existing pedals are prone to torsion in the process of cyclic rotation. It is transmitted to the inside of the threaded component, and the threaded component is prone to loosen after long-term use, resulting in the problem of pedal detachment
