杆秤在我国已有悠久的历史,由于它制作简单,使用方便,目前仍是常用的计量工具之一。根据量程的不同,杆秤又有大小之分,但大杆秤既粗又长,且有一个大秤砣,故携带不便,那么,能否制造一种既简单又轻便的量具来代替大杆秤呢?笔者经过多次试验,设计了一种《放大秤》,它与小杆秤配合使用,可将小杆秤的量程扩大10倍或数十倍,该项技术经中国专利局审查合格已授予专利权。现介绍如下,以抛砖引玉,期望得到同行们的指教。
Scales in our country has a long history, because of its simple production, easy to use, is still one of the commonly used measurement tools. According to the different range, rod scale and size of the points, but the rod scale is both thick and long, and there is a large scale 砣, so carrying inconvenience, then, can create a simple and lightweight gauges to replace the rod scale it? After many tests, designed a “zoom scale”, which used in conjunction with the small rod scale, small rod scale range can be expanded 10 times or dozens of times, the technology patent examination by the Chinese Patent Office has granted the patent. Now introduced as follows, in order to initiate, expect to get the advice of colleagues.
