Manual roller blinds are widely used in various places because of their beautiful appearance, simplicity, economy and practicality, strong and durable structure, etc., especially suitable for small-area windows and small glass curtain wall sunshades. When the roller blind is raised, its volume is so small that it is not easily noticed. When the roller blind fabric is lowered, it can soften the indoor light, avoid the trouble of direct sunlight, and achieve a good sun and light shading effect, especially the white coating. The fabric can also effectively regulate indoor temperature and reduce carbon emissions.
The manual bead rolling shutter system is mainly made of high-strength engineering plastics as raw materials. It is a mechanism modulated by the mechanical principle of unidirectionally controlling the passive shaft to perform rotary motion when the coil spring is twisted. Within the rated load range of the roller tube, it is ensured that the fabric will not slide down due to its own weight. The fabric will rise or fall by manually operating the beads for transmission, and the operation will be smooth and stable. According to the material of the beads, the bead-drawn roller blinds can be divided into plastic beads. There are two types of stainless steel pull beads, single width hand pull operation.
