As shown in fig. 3 and 5, each rope guiding seat 42 has a bottom wall 43, two opposite side walls 44, two opposite first vertical walls 45, two opposite second vertical walls 46, two opposite first guide rods 47, and two opposite second guide rods 48, wherein two opposite ends of the bottom wall 43 respectively have a second rope threading hole 431, and the second rope threading holes 431 are communicated with the bottom holes 32 of the bottom plate 31 of the upper beam 30; two side walls 44 are connected to two opposite long sides of the bottom wall 43; the two first vertical walls 45 are connected to the two short sides of the bottom wall 43 and embedded in the side holes 34 of the side plates 33 of the upper beam 30, and each first vertical wall has a first threading hole 451; the two second upright walls 46 are connected to the two opposite ends of the bottom wall 43, are positioned between the two first upright walls 45 and are respectively adjacent to the second stringing holes 431 of the bottom wall 43; the first guide rod 47 is horizontally arranged on the hole wall of the first stringing hole 451 of the first vertical wall 45; the second guide bar 48 is obliquely disposed between the first and second

upright walls

45, 46. One end of the lifting driving rope 49 is connected with the lower beam 20, the other end of the lifting driving rope 49 is connected with the rope winder 41, and the lifting driving rope 49 passes through the first rope passing hole 451 of the first vertical wall 45 of the rope guide seat 42 and is abutted to the first guide rod 47 and the second guide rod 48 in the wiring process, so that the smoothness of the operation of the lifting driving rope 49 can be increased by the first guide rod 47 and the second guide rod 48.

As shown in fig. 2, 3 and 5, the blade angle adjusting device 50 has a driving set 51, an angle adjusting rod 53, three angle adjusting seats 54, and three adjusting rope sets 55, wherein: the driving unit 51 is disposed in the upper beam 30 and has an operating portion 52 extending outside the upper beam 30. The angle adjustment rod 53 is disposed in the upper beam 30 and connected to the driving unit 51, such that the angle adjustment rod 53 can be driven by the driving unit 51 to rotate in place. The angle adjusting base 54 is pivoted between the two side walls 44 of the rope guiding base 42 in a one-to-one manner and connected with the angle adjusting rod 53, so that the angle adjusting base 54 can rotate relative to the rope guiding base 42 along with the angle adjusting rod 53. Each adjusting rope group 55 is provided with two opposite adjusting ropes 56 and a plurality of supporting rope rings 57, two ends of each adjusting rope 56 are respectively connected with the angle adjusting seat 54 and the lower beam 20, and the two adjusting ropes 56 respectively pass through the bottom hole 32 of the bottom plate 31 of the upper beam 30 through the second rope threading hole 431 of the bottom wall 43 of the rope guide seat 42 and are adjacently arranged on two opposite long side edges of the blade 35, so that the two adjusting ropes 56 have good routing smoothness; the bearing rope ring 57 is connected between the two opposite adjusting ropes 56 and sleeved on the blade 35 in a one-to-one manner; in addition, each adjusting rope 56 connects and is equipped with a plurality of spacing ropes 58 that are interval arrangement, and a lift driving rope 49 is located to the common cover of spacing rope 58 that is located same adjusting rope 56, can avoid taking place the condition of intertwine or interference between lift driving rope 49 and the adjusting rope 56.

If the blades 35 are to be folded, the blades 35 can be folded together by the upward pushing force of the user on the lower beam 20 and the winding force of the rope winder 41 on the lifting transmission rope 49 during the process of moving the lower beam 20 toward the upper beam 30. On the other hand, when the blade 35 is to be adjusted to be in an inclined state, first, the operating portion 52 of the driving set 51 is forced to rotate, the driving set 51 drives the angle adjusting rod 53 to rotate, the angle adjusting seat 54 is further driven to rotate in the process of rotating the angle adjusting rod 53, so that the angle adjusting seat 54 pulls one of the adjusting ropes 56, and then the pulled adjusting rope 56 pushes the blade 35 upward through the supporting rope 57 to follow the long side corresponding to the pulled adjusting rope 56, so that the blade 35 can be in an inclined state to provide a light shielding effect.

As can be seen from the above, the window covering 10 of the present invention does not require the hole processing of the blade 35, and can maintain the structural integrity of the blade 35, so that the blade 35 can provide a good light shielding effect after being adjusted to the inclined state. In addition, the curtain 10 of the present invention can improve the smoothness of the routing of the adjusting rope 56 and the lifting driving rope 49, and can prevent the mutual twisting or interference between them, thereby effectively improving the stability of operation.
