The invention relates to a bicycle handlebar folding structure which comprises an upper pipe body, a lower pipe body, a first locking mechanism and a second locking mechanism. The upper pipe body andthe lower pipe body are connected with each other. The first locking mechanism and the second locking mechanism lock a connection state of the upper pipe body and the lower pipe body. The upper pipe body is provided with a downward opening; an upper base body is arranged at the lower end of the upper pipe body; a protruding shaft column is arranged at the top end of the lower pipe body. The innerpipe body can correspondingly penetrate into the upper pipe body from the opening of the upper pipe body. A lower seat body is arranged at the upper end of the lower pipe body, the first locking mechanism and the second locking mechanism are arranged on two corresponding sides between the upper base body and the lower base body, the first locking mechanism is buckled and locked from the lower basebody to the upper base body, the second locking mechanism is pivoted with a pressing rod on a guide column penetrating through the upper base body, and the lower end of the pressing rod is pressed against the upper base body; and when a handlebar is folded, a state that the first locking mechanism is buckled with one side of the upper base body and one side of the lower base body and the pressingrod abuts against the upper base body is relieved firstly, the upper pipe body can be pulled upwards along the guide column till the shaft column of the lower pipe body is separated from the upper pipe body, and then the upper pipe body can be folded downwards with a shaft arrangement position of the guide column and the lower base body as the shaft.

    本发明有关于一种自行车手把折合结构,包括相互接合的上管体、下管体以及锁定上、下管体接合状态的第一锁定机构、第二锁定机构;上管体具有朝下的开口,上管体下端设上座体,下管体顶端设有凸出的轴柱,能对应由上管体的开口穿入上管体内,下管体上端设下座体,上、下座体之间在相对应的两边分别设第一锁定机构、第二锁定机构,第一锁定机构为由下座体向上座体扣合锁定,第二锁定机构则在穿过上座体的导柱上枢设抵压杆,并使抵压杆下端抵顶上座体;折合手把时,先解除第一锁定机构扣合上、下座体的一边以及抵压杆抵顶上座体的状态,便能使上管体沿着导柱向上拉升至下管体的轴柱脱离上管体的套合后,上管体便能以导柱与下座体轴设处为轴向下收折。
