一种不易变形的卷尺轮毂
摘要：
一种不易变形的卷尺轮毂，包括轮毂座和轮毂盖，其中轮毂座包括有圆片和与之连为一体、并与之垂直的圆筒片，所述的轮毂盖则扣合在该圆筒片的末端上，其特征在于在所述的圆筒片的末端还设置有至少二个轴向凸起部，而在轮毂盖则相应地开有可容该轴向凸起部插配其中的小孔。与现有技术相比，本发明由于在轮毂座的圆筒片末端又增设了凸起部来进一步加强定位，当轮毂受到较大的卷簧张力的时候，能够有效地防止轮毂的扭曲变形，延长了轮毂的使用寿命。
摘要（英）：

A tapeline wheel hub is not easy to deform which includes the wheel hub seat and the cover. The seat includes the wafer and the cylinder sheet which is vertical to the wafer. The wheel hub cover covers on the end of the cylinder sheet which is also set with at least two axis heave part. The holes opened on the wheel hub cover are inserted by the heave part. Compared to the present technology, theheave part is added to the cylinder sheet to intensify the location lock. So when the wheel hub suppresses the big spring coiling tensile, it can prevent it deform to prolong its life.
