The invention discloses a bicycle wheel disc capable of preventing a chain from falling off. The bicycle wheel disc comprises a shell, a wheel disc body, a chain, an extrusion mechanism, a cleaning mechanism and a limiting mechanism; the wheel disc body is movably arranged on one side of the shell, the outer side of the wheel disc body is movably sleeved with the chain, and the shell is connected with the extrusion mechanism, the cleaning mechanism and the limiting mechanism. The chain is connected with the extruding mechanism, the cleaning mechanism and the limiting mechanism, and the extruding mechanism comprises an adjusting mechanism and a buffering mechanism. By adjusting the height of a first gear, the height of a chain extruded by the bottom end of the first gear is changed, the degree of tightness of the chain can be changed at the moment, the chain can be tightened, the chain is effectively prevented from falling off, a brush is arranged, when the chain rotates through a rotating disc, friction is generated between the chain and the top end of the brush, and dust and silt on the chain can be brushed off through the anchor bolts, so that the chain is kept clean, and the service life of the chain is effectively prolonged.
本发明公开了一种防掉链自行车轮盘,包括壳体、轮盘、链条、挤压机构、清理机构和限位机构,所述壳体一侧通过活动设置有轮盘,所述轮盘的外侧活动套设有链条,所述壳体分别与挤压机构、清理机构和限位机构连接,所述链条分别与挤压机构、清理机构和限位机构连接,所述挤压机构包括调节机构和缓冲机构。本发明通过对第一齿轮的高度进行调整,使第一齿轮的底端挤压链条的高度发生改变,能够此时改变链条的松紧,能够使链条变紧,有效的避免链条发生脱落,且通过设置有毛刷,在链条通过转盘发生转动的时候链条与毛刷的顶端发生摩擦,通过锚栓能够将链条上的灰尘和泥沙刷下,使链条保持干净,有效的提高了链条的使用寿命。
