Abstract

一种指针式精度升级刻度盘，有主刻度盘和指针，其特征是：还有一个副刻度盘固定在指针上，主刻度盘与副刻度盘可相对转动，这种刻度盘，解决了一般指针式刻度盘指示数据精度较低的问题，具有成本低的优点，可适用于均匀刻度指针式侧量仪器用具。

Description

指针式精度升级刻度盘
本实用新型属于与一般测量有关的通用指示组件。
现有技术中的均匀刻度指针式测量仪器用具(包括各种仪表、衡器等)具有指示数据直接、迅速，但读数精度较低，量程扩大时，此问题更突出；而采用多级齿轮传动提高精度的方法，其缺点是结构复杂、成本高。
本实用新型的目的是，设计一种精度较高、成本低的刻度盘。
本实用新型有一个主刻度盘和指针，另有一个副刻度盘固定在指针上，主刻度盘与副刻度盘的刻度是相邻的，主刻度盘与副刻度盘可相对转动。
利用本实用新型，可使指针式测量仪原来的精度最大提高两个数量级(即达到原精度的1/100)，另外也不改变原测量仪的传动部分，因而结构简单、成本低。
图1：实施例1
图2：实施例2
图3：实施例3
图4：实施例4
图5：实施例5
图6：实施例6
实施例1至6都是按照将原仪器的精度提高到原分度值的1/5的情况来绘制的；
在实施例1的主刻度盘1最大刻度外，增加四格外延刻度，此四格外延刻度线上不标注数字，副刻度盘2为安在指针3上的一段圆弧，将其对应于主刻度盘1四格的长度五等分，等分线(即刻度值)分别标注0、0.2、0.4、0.6、0.8、1，指针3处在0刻度值处，如图1所示，当指针3指在主刻度盘1的15至16之间时，副刻度盘2中的0.6与主刻度盘1的外延刻度某条线刚好对齐，那么指针3所指的数字即为15.6；依次类推，实施例2的读数为4.2；实施例3的读数为31.4；实施例4的读数为-3.7；实施例5的读数为18.8；实施例6的读数为19.2。实施例1至4为主刻度盘不动，副刻度盘转动；实施例5和6为主刻度盘转动，副刻度盘不动。
