Abstract

本实用新型是钩式自行车辐条,现有的辐条弯度 大于90度,顶端膨大,安装拆卸程序繁琐,修理时间 长。本实用新型的最大特点是快速拆装安装,排除故 障时间短,其承受力不变,并能简化辐条生产工艺,节 约钢材。

Description

本实用新型是一种作业运输用具,更准确地说钩式自行车辐条。
中国是自行车的王国,全国各家自行车生产的辐条有13K、14K等不同型号,但每根辐条的形状一致,一端是螺纹,另一端是大于90度的弯,顶端膨大。在安装一辆新的自行车钢圈辐条时,不受任何物体影响,可是在完整的自行车上拆卸断旧辐条,更换新辐条时,修理工必须先拆下链罩,飞轮等物,才能安装数量较多的新辐条,若换少量的辐条时,还需把辐条慢慢弯曲,才能装上,最后用辐条板调正。因此,有拆装繁锁,安装费力,更换时间长,修理费用高等缺点。
本实用新型的目的在于提供一种快速拆装,排除故障,简化生产工艺的钩式辐条。
本实用新型的最大优点就是无须拆卸链罩,飞轮等任何零部件,把辐条直接钩入飞轮孔内即可成功。省时省力,降低修理费用,而且其承受力不变,更不易脱落。
附图系本实用新型的结构图。
附图描述了钩式自行车辐条的实施例。
一种钩式自行车辐条,其长度L,直径中根据自行车统一标准型号而定,螺纹(1)按13K,14K等型号的螺距M不变,钩端(2)的弯勾呈70度,顶端呈半球状,弯勾弧半径为2mm,钩长度为5mm,使用时,只需把钩端(2)挂勾在前轴花盘或后轴花盘上,螺纹(1)固定在钢圈上即可成功。

Claims (3)

1、一种“钩式自行车辐条”,其特征:由螺纹与钩端组成的辐条。
2、按权利要求1所述的钩式自行车辐条,其特征:螺纹螺距按标准型号13K,14K等不变。
3、按权利要求1、2所述的钩式自行车辐条,其特征:钩端的弯勾呈70度,顶端半球状,弯勾弧半径2mm,钩长5mm。
