The invention belongs to the field of experimental equipment, and particularly relates to a double-screw lifting device for a test box. In order to solve the problem that in the prior art, a storage plate cannot go up and down conveniently, the following scheme is provided, namely, a box body is included; sliding rails are installed on the inner walls of the two sides of the box body; first sliding blocks are installed on the sliding rails in a sliding mode; sliding plates are fixedly installed on the first sliding blocks; a wire hole is formed in the top side of any sliding plate in the vertical direction; second sliding blocks are slidably installed on the sides, close to each other, of the two sliding plates; the same storage plate is fixedly installed between the two second sliding blocks; two screws are fixedly installed at the bottom of the storage plate; and the bottom of the screw is sleeved with a screw guide sleeve in a threaded connection mode. According to the invention, the whole structure can be driven through a rope while the cover plate of the test box is opened, so that the height of the internal storage plate is adjusted, the height of the internal storage plate can be limited, and in the process of taking or storing experimental apparatuses, much time is saved for experimenters to take or place the apparatuses.

    本发明属于实验器材领域,尤其是一种试验箱用的双丝杆升降装置,针对现有的存在不能实现方便升降置物板问题,现提出如下方案,其包括箱体,所述箱体两侧内壁上均安装有滑轨,滑轨上滑动安装有第一滑块,所述第一滑块上固定安装有滑板,任意一个滑板的顶侧沿竖直方向开设有线孔,两个滑板相互靠近的一侧上均滑动安装有第二滑块,两个第二滑块之间固定安装有同一个置物板,所述置物板底部固定安装有两个丝杆,所述丝杆底部螺纹套接有丝杆导套,本发明可以在打开试验箱盖板的同时通过绳子带动整体结构,从而调整内部置物板的高度,且也可以限制其高度,在拿取或存放实验器材过程中,给实验人员拿取器材或者放置器材节省了不少时间。
