摘要
为克服现有水准仪脚架的连接螺旋易掉落的缺陷,该文自主研发了一种水准仪脚架连接装置。该装置包括一个卡接件(连接螺旋)和一个卡槽件(滑槽),制作简单、成本低。实验教学和实践表明,该装置不仅能有效保证水准仪与脚架之间的连接牢固性,而且使用或搬动脚架时,连接螺旋不会从滑槽中掉落。对水准仪脚架的改造提高了实用效果,更好地满足了专业需要,显著提高了教学质量。
The connecting screw of level tripod is easy to drop,so a connection device for level tripod is independently developed to overcome the shortcoming.The device that is easy to make and low in cost consists of a connecting screw and a coulisse.The experimental teaching and practice have indicated that the device can not only secure the firm connection between the level and the tripod,but also prevent the connecting screw falling off from the coulisse when using or moving the tripod.The restructuring has both increased the effect of level tripod and met the professional needs,thereby improving the teaching quality significantly.
