Abstract

The utility model relates to a coiling device of a curtain, which comprises a guide rail, and a coiling device and a hexagonal iron core that are arranged in the guide rail, wherein one end of the hexagonal iron core is connected with a brake, and the other end thereof passes through the coiling device and is sheathed and connected with a speed reducer; the coiling device comprises a bracket, a cover plate, a thread spool and a fixed sleeve which are sequentially connected; the thread spool and the fixed sleeve are rotatablely sheathed on the bracket; the thread spool takes on a conical shape and has a hollow structure; the large diameter end of the thread spool is provided with a baffle; a V-shaped groove is formed by the baffle and the thread spool; the large diameter end takes on conical transition; the end part of the baffle is provided with a convex column which is internally provided with a hexagonal axle hole; and the small diameter end of the thread spool is provided with more than one thread grooves. As the thread spool takes on the conical shape, and a coil rope is wound up gradually towards the left in the spiral direction along the right end of the thread spool, the coil rope forms a thread state and is wound on a rope spool in a screw type law; and furthermore, the coiling device and the guide rail are installed and disassembled without other tools, so that the coiling device of the curtain has the characteristics of quick installation, convenient use, safety and reliability.
