A sleeve is slidably connected to the third groove, and the sleeve can move along the length direction of the third groove. The first bracket is provided with a first groove and a second groove. Both the first groove and the second groove are arranged along the length direction of the first bracket. A moving block is slidably connected to the inner wall of the first groove, and the moving block can move along the length direction of the first groove. A plurality of moving blocks are distributed along the first groove. A blade is fixedly installed on the moving block, and the moving block can drive the blade to move left and right. The blade includes an extension portion at the top. The extension portion is inserted into the moving block, and when the moving block rotates, it can drive the blade to rotate. The top of the extension portion is connected to the sleeve. The width direction of the blade is arranged along the length direction of the moving block. At both ends in the width direction of the blade, there are respectively a convex portion and a concave portion. When the width direction of the blade is arranged along the length direction of the first groove, the convex portion of the blade is arranged opposite to the concave portion of the adjacent blade. When two adjacent moving blocks approach each other, the convex portion can be inserted into the concave portion.

[0005] The present invention is further configured such that the extension portion passes through the first groove, the second groove, the third groove, and the fourth groove. The upper part of the extension portion is inserted into the sleeve, and the extension portion is connected to the sleeve through a bearing.

[0014] ② The rotating block rotates, and the rotating block drives the blade to rotate, so that the width direction of the blade forms a parallel with the moving direction of the blade;

[0015] ③ The rightmost moving block drives the blade to move leftward together, and the convex part of the blade on the right side is inserted into the concave part of the blade on the left side;

[0016] ④ The rightmost moving block drives the blade to move rightward to the right extreme position together, so that the convex part of the blade on the right side disengages from the concave part of the blade on the left side, and the blade rotates back to the state where its width direction is perpendicular to the moving direction;

[0017] ⑤ The blade moves to the left side and folds up.

[0018] In summary, the present invention has the following beneficial effects:

[0019] When two adjacent moving blocks are in left - right abutment, the convex part is inserted into the concave part but not inserted to the deepest position of the inserted concave part to prevent the blade from being squeezed and deformed. After the convex part is inserted into the concave part, light shielding is formed between adjacent blades, improving the light - shielding effect and avoiding gaps between adjacent blades that would affect the light - shielding effect. Thus, the problem of poor light - shielding effect due to gaps between the louver blades is solved. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] As Figures 1 - 6 shown, this embodiment discloses a curtain pulling device, including a fixing frame 1. As Figure 1 shown, the fixing frame 1 is installed on the wall above the window frame 9.

[0031] As Figures 1 - 3 shown, the fixing frame 1 is provided with a first bracket 2. The upper end of the first bracket 2 is fixedly installed with a second bracket 3. Both the first bracket 2 and the second bracket 3 are strip-shaped structures. The second bracket 3 is provided with a third groove 31 and a fourth groove 32. Both the third groove 31 and the fourth groove 32 are arranged along the length direction of the second bracket 3. The fourth groove 32 is located above the third groove 31. The third groove 31 penetrates the upper wall of the second bracket 3, and the fourth groove 32 penetrates the lower wall of the second bracket 3. The third groove 31 and the fourth groove 32 are vertically connected. The width of the third groove 31 is smaller than the width of the fourth groove 32.

[0032] The lower end surface of the first bracket 2 abuts against the upper end surface of the first bracket 2. The first bracket 2 is provided with a first groove 21 and a second groove 22. Both the first groove 21 and the second groove 22 are arranged along the length direction of the first bracket 2. The width of the first groove 21 is larger than that of the second groove 22. The first groove 21 is located above the second groove 22. The first groove 21 and the second groove 22 are vertically connected. The upper end of the first groove 21 is connected to the lower end of the third groove 31, and the second groove 22 penetrates the lower wall surface of the first bracket 2.

[0033] As Figure 1 、 Figure 3 shown, a moving block 8 is slidably connected to the inner wall of the first groove 21. The moving block 8 can move along the length direction of the first groove 21. A plurality of moving blocks 8 are distributed along the first groove 21. Combined with Figure 5 , the moving block 8 is a strip-shaped structure, and both ends in the length direction of the moving block 8 are arc surfaces (not shown in the figure). As Figure 7 shown, the width of the first groove 21 matches the length of the moving block 8. As Figure 7 、 Figure 8 shown, driving components one 23 are installed at both ends in the width direction of the first bracket 2. The driving components one 23 are linear electric cylinders. A blocking rod 24 is installed at the output end of the driving component one 23. The blocking rod 24 is strip-shaped and the length direction thereof is arranged along the length direction of the first groove 21. When the moving block 8 rotates until its length direction is along the length direction of the first groove 21, the two side blocking rods 24 extend out and are close to the moving block 8 to form a limit.

[0034] As shown in Figure 1 、 Figure 3 FIGS.

[0035] A sleeve body 6 is slidably connected to a third groove body 31, and the sleeve body 6 can move along the length direction of the third groove body 31. The cross section of the sleeve body 6 is a cube structure, and the horizontal cross-sectional dimensions of the sleeve body 6 match the width and height of the fourth groove body 32 to prevent the sleeve body 6 from rotating when moving. The bottom surface of the sleeve body 6 is attached to the bottom surface of the fourth groove body 32, and the top of the extension portion 51 is connected to the sleeve body 6. Specifically, the extension portion 51 passes through the first groove body 21, the second groove body 22, the third groove body 31, and the fourth groove body 32. The upper portion of the extension portion 51 is inserted into the sleeve body 6, and the extension portion 51 and the sleeve body 6 are connected by a bearing 61. A sleeve cover 62 is fixedly installed at the top of the extension portion 51, and the sleeve cover 62 is located above the sleeve body 6.

[0036] As shown in [[ID= 25]]Figure 3 FIGS. Figure 6 As shown in

[0037] FIGS. Figure 1 、 Figure 3 When the width direction of the blade 5 is arranged along the length direction of the first groove body 21, the protruding portion 52 of the blade 5 is arranged opposite to the concave portion 53 of the adjacent blade 5. At this time, the length direction of the moving block 8 is also arranged along the length direction of the first groove body 21. When two adjacent moving blocks 8 approach each other, the protruding portion 52 can be inserted into the concave portion 53. When two adjacent moving blocks 8 are in left-right abutment, the protruding portion 52 is inserted into the concave portion 53 but not inserted to the deepest position of the concave portion 53 to prevent the blade 5 from being squeezed and deformed. After the protruding portion 52 is inserted into the concave portion 53, light shielding is formed between adjacent blades 5, improving the light shielding effect and avoiding the appearance of gaps between adjacent blades 5 that affect the light shielding effect.

[0038] As shown in Figure 1 、 Figure 3As shown, the first reel 7 and the second reel 71 are respectively installed on the left and right sides of the fixing frame 1, and both the first reel 7 and the second reel 71 are driven by their respective motors. An extension seat 63 is installed at the top of the rightmost sleeve cover 62. The first reel 7 is connected to the extension seat 63 through a first pulling rope 72. The rightmost sleeve cover 62 is connected to the second reel 71 through a second pulling rope 73. When the first reel 7 winds up the line, the second reel 71 pays out the line. When the second reel 71 winds up the line, the first reel 7 pays out the line.

[0039] As Figure 5 shown, connecting ropes 81 and 82 are respectively connected to both ends of the moving block 8 in the length direction. Adjacent moving blocks 8 are connected by the connecting ropes 81 and 82. When adjacent moving blocks 8 are parallel to each other in the length direction, the connecting rope 81 and the connecting rope 82 are parallel.

[0040] As Figure 1 、 Figure 2 shown, it further includes a rotating block 41. The rotating block 41 can rotate through the driving component 4. The driving component 4 is a rotary electric cylinder. The rotation mode of the rotating block 41 is to rotate back and forth, and the rotation angle is 92 degrees - 95 degrees.

[0041] The rotating block 41 is located on the left side of the first bracket 2. Both ends of the rotating block 41 in the length direction are connected to the leftmost moving block 8 through the connecting ropes 81 and 82. When the rotating block 41 and the moving block 8 are parallel to each other in the length direction, the connecting rope 81 and the connecting rope 82 are parallel.

[0042] The curtain pulling method of the above curtain pulling device includes the following steps;

[0043] ① As Figure 4 shown, when the width direction of the blade 5 is perpendicular to the moving direction of the blade 5, the second reel 71 winds up the second pulling rope 73, and the first reel 7 pays out the first pulling rope 72, so that the rightmost moving block 8 drives the blade 5 to move to the right together. Since adjacent moving blocks 8 are connected by the connecting ropes 81 and 82, each blade 5 is successively pulled out to the right. When the moving block 8 moves to the rightmost limit position, the connecting ropes 81 and 82 are kept in a tensioned state.

[0044] ② As Figure 1 shown, the rotating block 41 is driven to rotate by the driving component Ⅱ 4, and the rotation angle is 92 degrees - 95 degrees, so that the rotating block 41 drives the blade 5 to rotate through the connecting ropes 81 and 82, so that the width direction of the blade 5 is parallel to the moving direction of the blade 5. At this time, the blade 5 reaches the maximum light-shielding state. The actual rotation angle of the blade 5 is 90 degrees, and the rotation angle of the rotating block 41 is greater than the actual rotation angle of the blade 5 to ensure that the width direction of the blade 5 is parallel to the moving direction of the blade 5.

[0045] ③The shift lever 24 moves closer to the moving block 8, and the shift levers 24 on both sides limit the moving directions on both sides of the moving block 8. The first reel 7 winds up the first pull rope 72, and the second reel 71 releases the second pull rope 73, so that the rightmost moving block 8 drives the blade 5 to move leftward together. The convex part 52 of the blade 5 on the right side is inserted into the concave part 53 of the blade 5 on the left side to eliminate the light transmission caused by the gap between the blades 5 and improve the light shielding property of the curtain.

[0046] ④The second reel 71 winds up the second pull rope 73 and the first reel 7 releases the first pull rope 72, so that the rightmost moving block 8 drives the blade 5 to move rightward to the right extreme position together. As a result, the convex part 52 of the blade 5 on the right side disengages from the concave part 53 of the blade 5 on the left side, the shift levers 24 on both sides retract, the rotating block 41 rotates back, and the width direction of the blade 5 is perpendicular to the moving direction of the blade 5.

[0047] ⑤The first reel 7 winds up the first pull rope 72 and the second reel 71 releases the second pull rope 73, and the blade 5 moves leftward and closes up.

[0048] The above are only the preferred embodiments of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as the protection scope of the present invention.
