| 摘 要： | 介绍一种盒式方便收放单摆，内装卷式弹簧和摆绳，收放盒被固定在单摆支架立柱上端，前端开有缺口的摆绳悬挂板处于立柱上部，摆绳自收放盒拉出后陷入摆绳悬挂板前端的缺口中，摆球被连接于摆绳下端，它能使摆绳的收放如同使用钢卷尺一样方便自如，从而既为学生节省了大量无谓的调节时间，又使摆绳长度的测量更准确．该项目已申请国家发明专利（申请号：2006100221584）．

| Abstract: | A cassette convenient retractable pendulum is introduced.Spring contents roller re- tractable box and placed rope was placed with a fixed rope in the top pendulum supporter. This gap has opened a front plate placed rope at the upper column.Facing justice from the caf- eteria after facing justice retractable box hoisting rope placed into the gap between the front plate,the ball was placed on engaging rope connecting the bottom,it makes the retractable rope placed as easy as easily use the tape,students so as to save a lot of unnecessary regulation time,and also allows more accurate measurement of the length of facing justice.The project has applied for national patent.(Application No.:2006100221584) |
