The invention discloses a bicycle frame connecting structure, a bicycle frame with same and a gluing technology thereof. The bicycle frame connecting structure comprises a male connector and a female connector. The female connector is sequentially provided with a first annular plane, an annular step convex corner, a first annular inner side wall face, an annular inner side wall concave corner, a second annular inner side wall face, an annular inner side wall convex corner and a third annular inner side wall face from outside to inside. The male connector is sequentially provided with a first annular outer side wall face, an annular outer side wall concave angle, a second annular outer side wall face, an annular outer side wall convex angle, a third annular outer side wall face, an annular step concave angle and a second annular plane, yarn supplementing materials or yarn supplementing sleeves do not need to be used, and the bicycle frame is good in integrity. The gluing area is only provided with one tail end, so that the frame is good in strength and not prone to cracking. The male connector and the female connector are directly spliced, glued and heated after being glued, the working procedures are fewer, the working hours are shorter, the glued area is continuous and flat, and simple polishing treatment is performed in the later period, so that the working hours are reduced, the processing cost is reduced, and the production period is shortened.
本发明公开了自行车车架连接结构、应用该结构的车架及其胶合工艺,包括有互相配合的公接头和母接头,母接头从外向内依次设有第一环形平面、环形台阶凸角、第一环形内侧壁面、环形内侧壁凹角、第二环形内侧壁面、环形内侧壁凸角和第三环形内侧壁面,公接头依次设有第一环形外侧壁面、环形外侧壁凹角、第二环形外侧壁面、环形外侧壁凸角、第三环形外侧壁面、环形台阶凹角、第二环形平面,无需使用补纱料或补纱套管,使车架一体感较好;且胶合区域只有一个末端,车架强度较好,不易开裂;公母接头在涂胶后直接插接胶合和加热处理,工序较少且工时较短,由于胶合区域连续且平整,后期进行简单的打磨处理即可,减少工时,降低加工成本,减小生产周期。
