Description

Conveniently fixed roller blind and its fixing device

The invention relates to a roller blind, in particular to a roller blind that is convenient to fix and a fixing device thereof.

The use of curtains for shading or decoration in homes and offices has become a very popular phenomenon. However, for the opening and closing of curtains, most of them use drawstrings to open or close the curtains, but the curtains are only suitable for blinds or directional curtains. Curtains that are opened and closed at the left and right ends cannot be applied to a curtain. Therefore, the industry has developed a roller blind 1. As shown in Figures 1 to 3, the roller blind 1 has a rail 11, a tube 12, and two fixing brackets 13 respectively mounted on both sides of the rail 11. , And by means of a retractable and retractable device 14 provided at the left end of the tube body 12, the retractable and retractable device 14 has an elastic element 141 and a fixing device 142. When it is pulled once, the curtain cloth 16 moves downward and clockwise. When the curtain 16 is opened and pulled again, the curtain 16 is folded up counterclockwise, and when the curtain 16 is folded, it is slowly folded through a buffer device 15 provided at the right end of the tube body 12. However, the roller blind 1 has the following inconveniences during the assembly process: Since the fixing device 142 has a fixed inelastic range, if the rail 11 and the fixing bracket 13 installed on both sides of the rail 11 After the installation is completed, first install the elastic element 141 and the left end of the tube body 12 of the opening and closing device 14 of the fixing device 142 on the required window, or first install the buffer device 15 After the right end of the tube body 12, the other end of the tube body 12 cannot be fixed to the fixing bracket 13 on one side of the rail 11. Therefore, just like the assembly method shown in Figure 2, first, fix the rail 11 above the required window, and then install one of the fixing brackets 13 to one side of the rail 11 to fix it, and then successively fix the rail 11 Pull and open the elastic element 141, the fixing device 142, and the cushioning device 14 The punching device 15 is respectively assembled on the left and right ends of the pipe body 12, and is installed with the other fixing bracket 13, and then the other fixing bracket 13 is installed to the other side of the rail 11 and fixed to make the roll The assembly of the blind 1 is troublesome and time-consuming, which causes inconvenience in the assembly of the entire roller blind 1.
