Dome roof truss and dome roof truss-based tray type mechanical screen device
The invention relates to a screen device, in particular to a roof truss of the screen device. A dome roof truss comprises seven arc-shaped racks; first to fourth of the seven arc-shaped racks are hinged to an arc-shaped rack base through straight rod joints; fifth to seventh of the seven arc-shaped racks are hinged to the arc-shaped rack base through arc-shaped joints; and the rotating centers ofthe first to seventh of the seven arc-shaped racks are all positioned on the arc-shaped rack base. According to the roof truss provided by the invention, the fifth to seventh of the seven arc-shaped racks are hinged to the arc-shaped rack base through the arc-shaped joints, which ensures that a roof truss structure can be smoothly folded and unfolded, meanwhile, avoids membrane material tear and damage caused by relative transverse displacement among the arc-shaped racks, and prolongs the service life of the overall screen device. Meanwhile, the invention discloses a dome roof truss-based traytype mechanical screen device.
本发明涉及一种遮障装置，具体涉及一种遮障装置的屋架。一种穹顶屋架，包括：七榀弧形架；七榀弧形架中的第一至第四榀通过直杆接头与弧形架基座铰接，七榀弧形架中的第五至第七榀通过弧形接头与弧形架基座铰接，使七榀弧形架中的第一至第七榀弧形架的旋转中心均位于弧形架基座上。本发明中的屋架七榀弧形架中的第五至第七榀通过弧形接头与弧形架基座铰接，保证了屋架结构能够顺利收拢展开的同时，避免了各弧形架间的相对横向位移引起的膜材撕扯与损伤，提高了整个遮障装置的使用寿命。同时，本发明还公开了一种基于该穹顶屋架的托盘式机械化遮障装置。
