An end wall, a ring wall 41' extending from the end wall 411 toward the second weir 12, and a ring venting from the end wall 411 toward the reel space 312. The card wall 412 is fixedly Engaging with the second mounting seat 12, the fixing base 41 is fixedly disposed without synchronous rotation with the reel 31. The gear mechanism 42 includes a first gear disposed on the first portion of the reel 31 421, a fitting wheel below the first gear 421, a first wheel 422, a second and a second between the first and second walls ll2, 113 of the first mounting seat 11 The gear 422 is similar to the third gear that is drawn between the wheel 422 and the first frame wall 112. A drink is located above the third gear 423 of 201111614 and located at the first gear 421 and the first frame wall 112. a fourth gear 424, a long rod-shaped connecting member 425 interlocking with the fourth gear 424, and a second and third gear 422, a gear shaft 426 is disposed between the first and second frame walls 112 and 113. The first gear wheel 421 and the reel 31 are fixedly coupled to each other, so that the reel 31 can be rotated synchronously. The second and third teeth 422, 423 wheels are rotated in conjunction by the coupling of the gear shaft 426. The coupling member 425 includes a first joint portion 427 disposed in the spool space 312, and a first joint portion 427. a second connecting portion 428 extending to the left and having a long axis, the second connecting portion 428 passing through the centers of the first and fourth gears 421, 424, and the end is assembled in the first frame wall 112, the second The connecting portion 428 only passes through the first gear 421, but has no interlocking relationship with the first gear 421. The connecting member 425 is coupled with the fourth gear 424 by the second connecting portion 428, but There is no fixed relationship between the fourth gear 424 and the reel 31. Therefore, the number of rotations of the fourth gear 424 and the coupling member 425 is not synchronized with the number of rotations of the reel 31. The first, second, and second embodiments of the embodiment The third and fourth gears 421~424 are all spur gears, and by the first The number of teeth of the four gears 421 to 424 is designed to form a reduction gear set having a reduction ratio greater than one, and the number of teeth of the first to fourth gears 421 to 424 is N1, N2, N3, and N4, respectively, in this embodiment. , N2 > N1, N4 > N3, and the subtraction ratio of the reduced gear set = (Ν2 / Ν 1) χ (N4 / N3). The torsion member 43 is a coil spring and is mounted in the reel space 312 and located Between the fixing base 41 and the connecting member 425, the twisting member 43 201111614 includes a first section connecting the first connecting portion of the connecting member 425, and a second connecting the annular wall 413 of the fixing seat 41. Segment 432. Further, in the mounting of the present invention, in order to wind the curtain 32 (four) in the direction of _31 while the curtain 32 is unfolded, the flange 32 is slightly sag, and when the fixing seat 41 is assembled, the fixing seat needs to be first fixed. The rotation of the joint member 425 is a plurality of rotations relative to the joint member 425. The fixing portion 41 drives the first section 432 of the torsion member a to be twisted several times with respect to the first section 431, so that the torsion member has some slight torque and then The card wall 412 of the fixing base 41 is fixedly mounted. The second ampere 12' is mounted in a folded state, and is wound tightly around the outer circumference of the reel 31 with a slight tightness. Referring to Figures 2, 3, and 4', when the curtain 32 is unfolded as shown in Fig. 4, the small area of the edge 32 is only a small distance from the reel 31, and is expanded to the position shown in Fig. 2, and the side is opened. The strip 33 is pulled away from the reel 31 to pull the unfolded section 322 of the cord 32 away from the _ 31 to reach the (four) of the unfolding cord 32. When the cord 32 is unfolded, the reel 31 continues to rotate about its own central axis 'in the process', the first gear 421 rotates synchronously with the reel 31, and the second gear 422 meshing therewith is rotated, and the second gear is similar. The power of the third 423 is synchronously rotated by the gear shaft, and the fourth gear 424 is meshed with the fourth gear 424. The fourth gear 424 is further transmitted through the connecting member 425 to make the first section of the torsion member 43 relatively The first section 432 is twisted in the direction of the tightening, so that the user pulls the cord 32 to overcome the restoring force that the head 43 accumulates in advance during initial installation, and the curtain 32 is unfolded. Increase the power of twisting the number of turns. 201111614 The present invention transmits the twisting number of the torsion member 43 to be smaller than the number of rotations of the _31 by a suitable gear reduction design, assuming that the gear mechanism 42 has a ratio of 3, and the reel 31 rotates 6 times. The torsion member 43 of the gear mechanism transmission is only rotated 2 times, so if the coughing member 43 is first twisted 1 turn at the beginning of installation, when the cord 32 is stretched and unfolded, the user only needs to overcome the torsion member 43 to twist 12 The resilience caused by the circle (the original 〇 circle plus the required 2 turns) is sufficient. When the expanded area of the cord 32 is larger, the number of rotations of the reel 31 is larger, but the torque is increased and the rotation speed is reduced by the cooperation of the fourth to fourth teeth = 421 to 424, so that the torsion member u needs to be increased in rotation. The number is not too much. For example, when the reel 31 is rotated 9 times, the torsion member 43 is only rotated 3 times, allowing the user to pull relatively effortlessly. In summary, by the design of the transmission unit 4, when the curtain is deployed, the number of rotations of the torsion member 43 is the same as that of the fourth gear 424, and is not the same as the reel 31. Compared with the design, the torque of the torsion member 43 is increased to reduce the rotation speed and the number of torsion cycles, that is, the hair

The number of twisting turns of the torsion member 43 is always smaller than the number of turns of the reel 31, so that

The user can pull the curtain 32 more effortlessly and achieve the object of the present invention. The above is only the preferred embodiment of the present invention, and the scope of the present invention is limited to the scope of the present invention, that is, the simple equivalent of the scope of the patent application and the description of the invention. Variations and modifications are still within the scope of the invention.
