A chain disc convenient to install for the bicycle comprises a disc body, a movable cavity is formed in the disc body, a plurality of installation openings are formed in the inner side wall of the movable cavity, a plurality of clamping teeth are rotationally connected to the inner side wall of the movable cavity, and the clamping teeth penetrate through the installation openings and extend outwards; and an adjusting ring is rotatably connected to the inner side wall of the movable cavity, the clamping teeth are connected with the adjusting ring through a connecting mechanism, and an adjustingdevice matched with the adjusting ring is arranged on the front side of the disc body. The adjusting device is used for driving the adjusting ring to slightly rotate; the adjusting ring drives the clamping teeth to deflect through a rotating rod in the connecting mechanism; the clamping teeth deflect towards the inner side of the installation opening after deflecting, so that the outer diameter of the whole chain disc is reduced, the chain can be directly arranged on two chain discs in a sleeving mode, then arc-shaped blocks are rotated reversely to enable the clamping teeth to be inserted into the chain, the positions of the arc-shaped blocks are fixed through screws, and convenience is brought to chain mounting work.

    本发明公开了一种自行车用便于安装的链盘,包括盘体,所述盘体内部开设有活动腔,所述活动腔内侧壁开设有多个安装口,所述活动腔内侧壁转动连接有多个卡齿,多个所述卡齿均贯穿安装口并向外延伸;所述活动腔内侧壁转动连接有调节环,所述卡齿通过连接机构与调节环连接,所述盘体前侧设有与调节环相适配的调节装置。本发明利用调节装置带动调节环轻微转动,调节环通过连接机构中的转杆带动卡齿偏转,卡齿偏转后向安装口内侧偏转,从而使得链盘整体外直径缩小,进而可将链条直接套设在两个链盘上,然后反向转动弧形块使得卡齿插入链条内再利用螺钉将弧形块位置固定即可,给链条的安装工作带来了便利。
