Description

齿轮传动式自行车大车铃
本实用新型涉及一种自行车铃,更具体地涉及一种齿轮传动式自行车大车铃。
目前社会上销售和使用的自行车大车铃均采用拨摆式传动机构,铃锤为平面式,铃盖支架为拱形式,铃锤靠扳手弯脚和半圆槽拨摆其凸肩和铆钉起左右摆动并打击铃盖的作用,这种铃不仅结构复杂,制造精度高,而且体积大,重量重,拨动费劲。
本实用新型的目的在于提供一种结构简单,体积小,制造容易,使用方便的自行车大车铃。
本实用新型的构思是这样实现的:一种齿轮传动式自行车大车铃,由铃盖、中心柱、铃锤、扳手、铃底、铃夹组成,中心柱、扳手、铃底铆接固定为一体,扳手为外齿式,中心柱上套有齿轮和铃锤臂,齿轮与铃锤臂固定为一体,铃锤臂与铃锤通过弹簧连接,铃底的圆边上设置有窗板,外齿式扳手与齿轮啮合传动。
本实用新型由于外齿式扳手与齿轮啮合传动,弹性铃锤通过齿轮传动而旋转,在窗板的阻挡下,使铃锤产生一外弹力而撞击铃盖发生铃声。本实用新型结构简单,体积小,制造容易,使用十分方便。
下面结合附图和实施例对本实用新型作进一步说明。
附图为本实用新型结构示意图。
如图,由铃盖1、中心柱11、铃锤7、铃底6、铃夹5、扳手3组成的本实用新型,中心柱11、扳手3、铃底6铆接成一体,扳手3为外齿式,齿轮2与铃锤臂9固定为一体,并套于中心柱11上,铃锤臂9与铃锤7通过弹簧8弹性连接,铃锤7为球形,铃底6的圆边上设置有两个窗板10,窗板10为圆弧形,且置于铃底圆边的内侧,扳手3的外齿式与齿轮2啮合。
