The invention discloses a usable area adjustable sand table for engineering management. The usable area adjustable sand table comprises a base and a panel, the panel is slidably connected with the upper part of the base, and the upper surface of the panel is used for arranging the sand table; a first strip-shaped sliding groove and a second strip-shaped sliding groove are symmetrically formed in the upper end of the interior of the base, a first sliding block is slidably connected into the first strip-shaped sliding groove, a second sliding block is slidably connected into the second strip-shaped sliding groove, the panel comprises a first panel body and a second panel body, the lower surface of the first panel body is fixedly connected with the first sliding block, and the lower surface of the second panel body is fixedly connected with the second sliding block; and a positioning plate, a lifting mechanism and a driving part are arranged in the base, the lower surface of the positioning plate is fixed to the actuating end of the lifting mechanism, the lifting mechanism and the driving part are fixedly arranged in the base, and the driving part is used for driving the actuating endof the lifting mechanism to ascend and descend in the vertical direction. According to the sand table for engineering management, the use area of the sand table can be expanded conveniently, and theproblems that an existing sand table needs to be expanded outside and needs to be fixed and combined again are solved.

    本发明公开了一种可调节使用面积的工程管理用沙盘,包括底座和面板,面板与底座的上部滑动连接,面板的上表面用于布置沙盘;底部内部的上端对称开设有第一条形滑槽和第二条形滑槽,第一条形滑槽内滑动连接第一滑块,第二条形滑槽内滑动连接第二滑块,面板包括第一面板和第二面板,第一面板的下表面固连与第一滑块,第二面板的下表面固连与第二滑块;底座内设置定位板、升降机构和驱动部,定位板的下表面固定与升降机构的执行端,升降机构和驱动部固定设置在底座内,驱动部用于驱动升降机构的执行端在竖直方向上升降。本发明的工程管理用沙盘具备方便扩展沙盘使用面积,解决了现有的沙盘需要在外部进行扩展,需要重新固定以及组合的问题。
