Composition of folding door components

Folding doors mainly consist of door frames, door leaves, transmission components, rotating arm components, transmission rods, directional devices, etc. This door type can be installed indoors and outdoors. Each door has four door leaves, with two side door leaves and two middle door leaves each. The frame on one side of the side door leaf is connected to the middle door leaf by a hinge. The upper and lower ends of the stile on the other side of the side door leaf are respectively equipped with upper and lower rotating shafts, which are connected to the upper and lower rotating shaft seats of the door frames on both sides of the door opening. The side door stile will rotate around one side stile, while driving the middle door leaf to rotate to 90 ° together to open and close the door leaf. When powered, the upper rotating shaft end is equipped with rotating arm components and transmission components, and the upper and middle parts of the door frame are equipped with transmission components and door opening machines; There is a directional device on the middle door leaf. After the door opening machine operates, it drives the two gears of each transmission component to rotate, and the two teeth that align with it move in a straight line. The other end of the teeth is connected to the rotating arm, which moves in a circular direction. The side door frame rotates around one side stile, electrically opening the door leaf. The middle and tight joints of the two door leaves are equipped with safety protection devices, which can return to the fully open state when encountering obstacles when closing, ensuring safety and reliability. The door opening has a width of 3000-4800mm and a height of 3000-4800mm, with a total of 26 specifications, both electric and manual.
