Master's hard fast door is mainly connected by hinge, 0.7mm aluminum plate thickness, foaming door plate thickness 40mm, 50mm series connection, note that when the hinge and door panel are fixed, ensure the seal between the door panel and the door panel tight. Then connect all the door panels into a sheet-like chain system. The hinge chain on both sides has high-quality rolling bearing wheels, and the bearing wheels roll in the rails on both sides. Due to the consideration of friction and wear, the track must be made of aluminum alloy, and when the two sides of the track extend upward, the top end adopts The spiral track, that is, the principle of the Archimedes spiral, is used to fix the spiral track whose arc radius is linearly reduced at the top of the track on both sides. When the door body is drawn into the spiral track, the door body is mutually no collisions between them.
