What is the principle of movable partition?

A folding movable partition composed of multiple partition fans. There are two kinds: wide fan type and narrow fan type. Wide fan partition is the same as press movable partition. The upper part of each partition is installed on the guide rail with a group of pulleys that can change direction, and the partitions are connected by hinges, which can be folded and pushed into the storage room when not in use. This kind of partition is restricted by many factors, and it may not be easy to push it if it is not handled properly, so there is a double folding type with two partitions. The width of the narrow fan folding movable partition is often 10~30 cm, with soft double folding and hard single folding (Figure 2). Rigid single folding type, mostly using fiberboard, plastic plate or thin steel plate as partition fan, using plastic or metal as hinge. Each partition fan is installed on the guide rail with a set of pulleys that can change direction, forming a foldable sliding partition. Double-folded soft multi-purpose thin steel plate is made into a telescopic articulated skeleton, and the skeleton is provided with pulleys, which are loaded into guide rails. Both sides of the hinge frame are equipped with soft artificial leather or plastic sheets, which can be folded and opened like an accordion. This partition is light in weight, beautiful, convenient to install, can be enclosed in an arc, and is flexible to use. The interlayer can also be lined with thin steel plates and sound-absorbing materials to improve the sound insulation ability.
