Abstract

The invention discloses an adjusting structure for a seat tube of a bicycle, and relates to the technical field of electric bicycle accessories. The adjusting structure comprises a vertical tube and the seat tube, and a saddle is arranged on the seat tube. The adjusting structure further comprises a swivel support and a swivel. The swivel support is arranged above the vertical tube, and an inner cavity of the swivel support is hemispherical. The swivel is arranged in the cavity of the swivel support, the swivel is provided with a deep groove, and the lower end of the seat tube is inserted into the deep groove of the swivel. The upper end of the seat tube is connected with the saddle. The swivel support and the swivel have the degree of freedom of relative rotating. Front-back displacement adjustment of the saddle is achieved, the labor intensity of a rider is lowered, and operation is convenient.

Description

technical field [0001] The invention relates to the technical field of bicycle manufacturing, in particular to a bicycle seat tube adjustment structure. Background technique [0002] As a means of transportation, bicycles have been integrated into people's lives. With the changes in people's lifestyles, various bicycles with special uses based on bicycles have gradually entered our lives, such as bicycles for fitness. Mountain bikes, gear shifters for faster cycling, and more. In the structure of the bicycle, the seat is set on the standpipe, and the seat supports most of the weight of the rider. Due to the difference in height and body shape of the rider, the front and rear inclination angles of the seat are also required to be adjusted to suit themselves. The best state, thereby reducing the physical exertion of cycling. [0003] In the prior art, only the adjustment of the height is generally considered for the installation structure of the tube of the seat, such as fi...
