2 Disclosed is a double-drum type curtain drum module, comprising a shell base 3 having two compartments, a first guide wheel, a second guide wheel, an auxiliary cord 4 rotator installed in a first compartment, and two cord drums installed in a second 5 compartment. At least two reinforcing bars in parallel are formed in the first compartment. 6 A plurality of first wheel-connecting grooves are formed on the reinforcing bars for 7 installing the first guide wheel. The second compartment has a plurality of second 8 wheel-connecting grooves formed on a bottom surface of the shell base for installing the 9 second guide wheel. A connecting channel is formed between the reinforcing bars and 10 exposed from the bottom surface of the shell base. The connecting channel extends into 11 the second compartment for coupling the first wheel-connecting grooves and the second wheel-connecting grooves. A control cord reset opening is formed from the first guide wheel to a first end of the connecting channel to align between the curtain auxiliary cord access holes. A control cord transferred opening is formed from the second guide wheel to a second end of the connecting channel. Accordingly, what is solved is the rubbing issue of conventional control cord against the topmost curtain sunshade blade caused by conventional control cord being oblique to the curtain auxiliary cords adjacent to the control cord access holes. |
