Patent number: 11679830Abstract: A bicycle seat post structure includes an upper tube, a lower tube, a height adjusting mechanism and at least one sliding member. The upper tube includes at least one stopping member. The lower tube has a first edge. The sliding member is movably disposed in the lower tube. The stopping member does not abut against the sliding member as the stopping member is in a first position. When the height adjusting mechanism is operated to allow the upper tube to move along an axial direction, the stopping member is switched to a second position and is restricted by the sliding member. The sliding member is operated to move along the axial direction so as to be positioned from one of a plurality of positions to another one of the plurality of positions, thereby changing a distance between the stopping member in the second position and the first edge.Type: GrantFiled: October 20, 2021Date of Patent: June 20, 2023Assignee: LIMOTEC METAL INDUSTRY LIMITEDInventors: Tzu-Chien Tso, Yao-Chin Yang, Chih-Cheng Cheng, Huan-Wei Liu
