The invention discloses a carbon fiber spoke, a bicycle rim and a bicycle, the carbon fiber spoke comprises a carbon fiber spoke body, a first connecting piece and a second connecting piece, a first spiral column and a second spiral column are integrally formed at the two ends of the carbon fiber spoke body respectively, a first spiral hole is formed in the first connecting piece, and a second spiral hole is formed in the second connecting piece; the first connecting piece and the second connecting piece are connected to the two ends of the carbon fiber spoke body through male and female screw fit of the first screw hole and the first screw column and male and female screw fit of the second screw hole and the second screw column correspondingly. Gluing gaps are reserved between the peripheral wall of the first spiral column and the inner wall of the first spiral hole and between the peripheral wall of the second spiral column and the inner wall of the second spiral hole, and the gluing gaps are filled with adhesives. The mechanical strength of the joints of the two ends of the carbon fiber spoke and the first connecting piece and the second connecting piece is high, and a double fixed connection structure can be formed by combining male and female screw matching and adhesive bonding.
本发明公开一种碳纤维辐条、自行车轮圈和自行车,包括碳纤维辐条本体、第一连接件和第二连接件,碳纤维辐条本体的两端分别一体成型有第一螺旋柱和第二螺旋柱,第一连接件上形成有第一螺旋孔,第二连接件上形成有第二螺旋孔,第一连接件和第二连接件分别通过第一螺旋孔与第一螺旋柱以及第二螺旋孔与第二螺旋柱的公母螺旋配合连接在碳纤维辐条本体的两端上,且第一螺旋柱的周壁与第一螺旋孔的内壁之间以及第二螺旋柱的周壁与第二螺旋孔的内壁之间均预留有胶合间隙,胶合间隙中填充有胶合剂。本发明的碳纤维辐条其两端与第一连接件和第二连接件连接处的机械强度高,通过公母螺旋配合结合胶合剂粘接可形成双重固定连接结构。
