Abstract

本实用新型公开一种多功能度量仪,主要包括刻度尺(1)和盖板(2),在刻度尺(1)和盖板(2)之间设有两个滑轮(3),其中一滑轮(3)伸出刻度尺(2)的尺端,两滑轮(3)之间通过度量线(4)连接。在测量时只需将伸出刻度尺端头的滑轮沿曲线滚动即可从刻度尺上直接读出所测曲线的长度,本实用新型具有结构简单、使用方便且测量精度高的优点。

Description

多功能度量仪
本实用新型涉及测量仪器领域,特别是一种用于测量曲线长度的度量仪。
目前,中小学校在教学中常遇到曲线长度无法测量的问题,比如在圆周长公式推导教学时,只好采用硬纸片自制一个圆放在直尺上滚动量得,在实际操作中误差很大;另外在实际生活和工作中也经常遇到曲线长度难以准确测量的烦恼,往往只是粗算一个大概而已。
本实用新型的目的在于提供一种结构简单、操作方便且测量精度高的多功能度量仪。
本实用新型的目的是通过以下技术方案实现的:它主要包括刻度尺和盖板,在刻度尺和盖板之间设有两个滑轮,其中一滑轮伸出刻度尺的尺端,两滑轮之间通过度量线连接。
由上述技术方案可见,在测量时只需将伸出刻度尺端头的滑轮沿曲线滚动即可从刻度尺上直接读出所测曲线的长度,本实用新型具有结构简单、使用方便且测量精度高的优点。
附图说明:
图1为本实用新型实施例结构示意图;
图2为图1A-A视图。
下面结合附图对本实用新型作进一步说明:
如图1和图2所示,刻度尺1、盖板2可选用木板或塑料类板材,刻度尺1和盖板2长度相同,盖板2的宽度略窄于刻度尺1,使得刻度尺1上的刻度显露出来,在两者之间的两端头设置两个滑轮3,其中一个滑轮3伸出尺端,两滑轮3之间通过度量线4连接,为便于测量,度量线的长度最好为总刻度的整数倍,另外在刻度尺1上还设有一度角器5 。使用时在度量线4上总刻度整数倍处标注标记点对准刻度尺的“0”,伸出尺端的滑轮3沿曲线滑动,最后标记点通过的次数乘以总刻度加上标记点所处的刻度数即为所测曲线长度。
