Abstract

The invention discloses a bicycle seat adjusting device. The bicycle seat adjusting device comprises a seat tube and a transverse shaft, wherein a cushion is supported by the seat tube. A positioningdevice, a linkage wheel and a handle are arranged on the transverse shaft from left to right in sequence, wherein the linkage wheel is in transmission connection with the positioning device, and the handle is fixedly connected with the right end of the transverse shaft. The positioning device comprises a casing. An elastic stopping ring is arranged on the inner side of the casing. A rotating wheelis arranged on the annular inner side of the elastic stopping ring and is in clearance fit with the elastic stopping ring. The linkage wheel comprises a gear and a stopping bar in linkage with the gear. The stopping bar extends into a first notch to be linked with a stopping block. The rack is arranged on the seat tube and meshed with the gear. The transverse shaft is rotatably connected with thelinkage wheel. The elastic stopping ring plays stopping and positioning roles under the action of friction force when expanding outwards. The process of dismantling and tightening bolts is omitted byadjusting the cushion through the steps.

Description

technical field [0001] The invention relates to the technical field of bicycle spare parts, in particular to a bicycle seat adjusting device. Background technique [0002] As a representative of low-carbon and green travel, shared bicycles have become a common means of transportation in daily life. During riding, the height of the cushion is related to the riding comfort and whether it saves effort. The seat cushion adjustment of present bicycle all is to adjust the height by loosening fastening bolts, after pressing or extracting seat, then use fastening bolt to fix seat cushion. Not to mention the inconvenience of adjustment, the most frustrating thing is that some users tighten the bolts with too much force, resulting in too much pre-tightening force of the bolts, and later users have to use a lot of force to loosen the bolts, or even not loosen at all. However, the cylinder-type lifting mechanism may cause an explosion hazard due to bumps during riding, so it cannot be...
