More Information
Summary:The utility model discloses a multifunctional conic curve gauge. The multifunctional conic curve gauge comprises four equal-length connection rods, a diagonal connection rod and a movable connection rod, wherein the four equal-length connection rods are connected in a pivoted mode from head to end to form a rhombic structure; the diagonal connection rod is arranged on two endpoints of one diagonal line of the rhombic structure, one end of the diagonal connection rod is connected to one endpoint of the diagonal line in a pivoted mode, and the other end of the diagonal connection rod is connected to the other endpoint of the diagonal line in a slidable mode; one end of the movable connection rod is connected to one of two endpoints of the other diagonal line of the rhombic structure, and the other end of the movable connection rod is a free end. The middle of the diagonal connection rod is provided with a through sliding groove extending in the length direction of the diagonal connection rod, the middle of the movable connection rod is provided with a through sliding groove extending in the length direction of the movable connection rod, and a drawing pencil is placed at the joint of the diagonal connection rod and the movable connection rod and penetrates through the through sliding groove of the diagonal connection rod and the through sliding groove of the movable connection rod at the same time. The multifunctional conic curve gauge is simple in structure, convenient to carry and operate and capable of serving as not only a tool for drawing conic curves but also a demonstration teaching aid of a connection rod mechanism in machine foundation teaching.
