带空间模型线管拉伸式联动的直线三面投影演示板
摘要：
一种带空间模型线管拉伸式联动的直线三面投影演示板，包括投影板、空间直线模型机构、投影连线机构、直线投影机构和联动机构。本发明在原柔性牵引线管拉伸式联动的直线三面投影演示板基础上加入了空间模型并采用直线空间模型与直线投影联动的结构，尤其是采用两条定长的线管和线管内能移动的封闭线绳的结构，确保动点的水平投影到X轴的距离等于侧面投影到Z轴的距离。更直观显现空间直线的位置变化与其投影的变化的关系。操作方便，使用时只要控制动点的正面投影，就能自动牵动动点水平投影和侧面投影，能摆出空间直线的正平线、水平线、侧平线、正垂线、铅垂线、侧垂线和倾斜线7种位置。演示效果显著提升。使直线三面投影演示板更加完善。
摘要（英）：

The invention relates to a line tube tensile type linked straight line three-surface projection demonstration board with a spatial model. The line tube tensile type linked straight line three-surface projection demonstration board includes a projection board, a space straight line model mechanism, a projection line connection mechanism, a straight line projection mechanism and a linkage mechanism. According to the line tube tensile type linked straight line three-surface projection demonstration board provided with the spatial model of the invention, based on an original flexible traction line tube tensile type linked straight line three-surface projection demonstration board, the spatial model is additionally adopted, and a straight line spatial model and straight line projection linked structure is used; a structure composed of two fixed-length line tubes and closed ropes which can move in the line tubes is adopted, so that it can be ensured that a distance between the horizontal projection of a moving point to an X axis is equal to a distance from the lateral projection of the moving point to a Z axis; the relationship between the change of the position of a spatial straight line and the change of the projection of the spatial straight line can be displayed more intuitively; the line tube tensile type linked linear straight line three-surface projection demonstration board is convenient to operate, when the line tube tensile type linked straight line three-surface projection demonstration board is used, as long as the front projection of the moving point is controlled, the horizontal projection and lateral projection of the moving point can be automatically moved, and the frontal line, horizontal line, profile line, normal line, plumb line, perpendicular line of which the orthocenter is not a midpoint, inclination line of the spatial straight line can be demonstrated; and the straight line three-surface projection demonstration board can be further improved.
