Abstract

A safe rocker device for a rolling curtain comprises a reel (4) used for mounting of the rolling curtain, a fixing portion (3) used for fixing the reel (4), and a first driving portion (1) and a second driving portion (2) used for driving the reel (4) to rotate. The first driving portion (1) and the second driving portion (2) drive by using a bead chain (14). The reel (4) is driven by the second driving portion (2). The first driving portion (1) comprises a chain shaft box (11), a rotating mechanism (12), and a chain shaft frame (13). The chain shaft frame (13) is mounted in the chain shaft box (11), and driven by the rotating mechanism (12). The chain shaft frame (13) is meshed with the bead chain (14), and drives the bead chain (14) to rotate by using the rotating mechanism (12). The bead chain (14) drives the second driving portion (2) to run to drive the reel (4) to move, so as to implement the dropping-down or rolling-up of curtain cloth. By providing a force needed in the dropping-down or rolling-up of a window curtain by using a hand crank of the first driving portion (1), the problem is solved that it is difficult to roll up the curtain cloth because a fault is highly likely to occur between a pulling rope and a gear due to an uneven force when the pulling rope is pulled.

Background technique:

 Manual roller blinds are widely used due to their many advantages such as beautiful appearance, economical and practical structure and durability. When the curtain is raised, its volume is so small that it is not easy to detect inside. When the curtain is lowered, the light in the room can be softened, and the direct sunlight can be avoided, achieving a good shading effect. At present, manual roller blinds on the market generally have two kinds of spring roller blinds and roller blinds. The spring force of the spring roller blind can adjust the height of the curtain to rise and fall within a certain range. It can be stopped at any position, and the curtain can be gently pulled down. After the hand is released, the curtain will automatically bounce back to the top of the curtain. However, the roller blind of such a structure has a lower load-bearing range of the reel and is not suitable for a curtain having a large area. One end of the pull-up roller reel has a gear and a beaded drawstring that cooperates with the gear, and the pull rope generates power, and the reel is used to drive the reel to receive or release the curtain. The disadvantage of the curtain is that the force is not during the pulling process. It is easy to cause trouble between the drawstring and the gear, which makes it difficult to wind up the curtain upwards, or the winding speed is slow, not convenient enough, and the exposed drawstring of the bead can easily cause accidental injury to the child.
