The single pin-driven running-assistant universal wheel is characterized in that a drive gear (8) is arranged at the inner side edge of the roller wheel (1), a shaft sleeve (9) is arranged at the inner side edge of a wheel frame (3), a gear shaft (10) is installed in the shaft sleeve (9),one end of the gear shaft (10) is provided with a gear (11) meshed with the drive gear (8), the other end of the gear shaft (10) is installed with a drive gear (12) meshed with a drive rack (13) which is installed in a guide slot (14), the guide slot (14) is installed on an installation plate (15), and both sides of the installation plate (15) are respectively connected with the corresponding wheel frame (3); the upper end of the drive rack (13) is connected with the lower end of a drive rod (16), the upper end of the drive rod (16) penetrates in a central hole of a bearing seat (5) with a guiding function, and the lower end of the drive rod (16) is connected with an elastic resetting device (17); and a clutch (21) is installed on the installation plate (15). The invention has the advantages of simple structure, small volume and convenient and labor-saving use.

Description

technical field [0001] The invention relates to a single wheel for sports equipment, especially a structure of a caster that can be used on sports equipment driven forward by pedals on a non-powered sports device such as a skateboard, specifically a single-leg driving aid universal wheel. Background technique [0002] At present, with the development of the country's economy and the improvement of people's living standards, people gradually pay attention to improving the quality of life, especially parents pay more attention to improving the quality of life of their children. Therefore, in order to enrich the life of teenagers, various entertainment and fitness apparatuses emerge in an endless stream, such as scooter, pedal tricycle etc. are all invented and manufactured one after another. These devices are generally driven forward by using the person's feet to push back on the ground or the deflection of the center of gravity of the human body to generate the forward momen...
