DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

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

[0031] like Figure 1-Figure 3 As shown, the fixing frame 1 is installed with a first bracket 2, and a second bracket 3 is fixedly installed on the upper end of the first bracket 2. Both the first bracket 2 and the second bracket 3 are long strip structures. The second bracket 3 is provided with a third slot 31 and a fourth slot 32. The third slot 31 and the fourth slot 32 are both arranged along the length direction of the second bracket 3. The fourth slot 32 is located above the third slot 31. The third slot 31 passes through the upper wall of the second bracket 3, and the fourth slot 32 passes through the lower wall of the second bracket 3. The third slot 31 and the fourth slot 32 are connected up and down. The width of the third slot 31 is smaller than that of the fourth slot 32.

[0032] The lower end surface of the first bracket 2 is in contact with the upper end surface of the first bracket 2. The first bracket 2 is provided with a first slot body 21 and a second slot body 22. The first slot body 21 and the second slot body 22 are both arranged along the length direction of the first bracket 2. The width of the first slot body 21 is greater than that of the second slot body 22. The first slot body 21 is located above the second slot body 22. The first slot body 21 is connected with the second slot body 22 up and down. The upper end of the first slot body 21 is connected with the lower end of the third slot body 31. The second slot body 22 passes through the lower wall of the first bracket 2.

[0033] like Figure 1 , Figure 3 As shown, the inner wall of the first slot body 21 is slidably connected with a moving block 8, and the moving block 8 can move along the length direction of the first slot body 21. A plurality of moving blocks 8 are distributed along the first slot body 21. Figure 5 The moving block 8 is a long strip structure, and both ends of the moving block 8 in the length direction are arc surfaces (not shown in the figure). Figure 7 As shown, the width of the first slot 21 matches the length of the moving block 8. Figure 7 , Figure 8 As shown, driving components 23 are installed at both ends of the first bracket 2 in the width direction. The driving component 23 is a linear electric cylinder. A stopper 24 is installed at the output end of the driving component 23. The stopper 24 is long and its length direction is arranged along the length direction of the first slot body 21. When the moving block 8 rotates to the point where its length direction is along the length direction of the first slot body 21, the stopper 24 on both sides extends out and approaches the moving block 8 to form a limit.

[0034] like Figure 1 , Figure 3 As shown, the moving block 8 is fixedly mounted with a blade 5, which is a shutter blade and is a thin plate structure. The blade 5 includes an extension portion 51 located at the top, which is a cylindrical structure, and the axis of the extension portion 51 is on the center line of the length direction of the blade 5. The extension portion 51 is inserted into the moving block 8 by interference fit, and the upper end of the extension portion 51 extends out of the moving block 8. The outer wall of the extension portion 51 is provided with a protrusion, and the inner wall of the moving block 8 is provided with a corresponding groove. The protrusion on the outer wall of the extension portion 51 is inserted into the groove of the moving block 8, and the moving block 8 can drive the blade 5 to rotate when the moving block 8 rotates.

[0035] The third slot body 31 is slidably connected with the sleeve body 6, and the sleeve body 6 can move along the length direction of the third slot body 31. The cross section of the sleeve body 6 is a cubic structure, and the horizontal cross-sectional size of the sleeve body 6 matches the width and height of the fourth slot body 32 to prevent the sleeve body 6 from rotating when moving. The bottom surface of the sleeve body 6 fits the bottom surface of the fourth slot body 32, and the top of the extension part 51 is connected to the sleeve body 6. Specifically, the extension part 51 passes through the first slot body 21, the second slot body 22, the third slot body 31, and the fourth slot body 32, and the upper part of the extension part 51 is inserted into the sleeve body 6. The extension part 51 is connected to the sleeve body 6 through a bearing 61, and a sleeve cover 62 is fixedly installed on the top of the extension part 51, and the sleeve cover 62 is located above the sleeve body 6.

[0036] like Figure 3 As shown, the width direction of the blade 5 is arranged along the length direction of the moving block 8. Figure 6 As shown, a protrusion 52 and a recessed portion 53 are respectively provided at both ends of the blade 5 in the width direction. The protrusion 52 protrudes outward along the width direction of the blade 5, and the recessed portion 53 is recessed inward along the width direction of the blade 5. The protrusion 52 can be inserted into the recessed portion 53, and the recessed depth of the recessed portion 53 is greater than the protruding depth of the protrusion 52.

[0037] like Figure 1 , Figure 3 As shown, when the width direction of the blade 5 is arranged along the length direction of the first slot body 21, the raised portion 52 of the blade 5 is arranged opposite to the recessed portion 53 of the adjacent blade 5. At this time, the length direction of the moving block 8 is also arranged in the length direction of the first slot body 21. When two adjacent moving blocks 8 are close to each other, the raised portion 52 can be inserted into the recessed portion 53. When the two adjacent moving blocks 8 are abutted left and right, the raised portion 52 is inserted into the recessed portion 53 but not inserted to the deepest position of the recessed portion 53 to prevent the blade 5 from being squeezed and deformed. After the raised portion 52 is inserted into the recessed portion 53, a light shielding is formed between the adjacent blades 5, thereby improving the light shielding effect and preventing the occurrence of gaps between adjacent blades 5 to affect the light shielding effect.

[0038] like 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 the first reel 7 and the second reel 71 are driven by their own motors. An extension seat 63 is installed on the top of the cover 62 located on the far right, and the first reel 7 is connected to the extension seat 63 through a pull rope 1 72, and the cover 62 located on the far right is connected to the second reel 71 through a pull rope 2 73. When the first reel 7 is winding, the second reel 71 is unwinding, and when the second reel 71 is winding, the first reel 7 is unwinding.

[0039] like Figure 5 As shown, the two ends of the moving block 8 in the length direction are respectively connected with a connecting rope 1 81 and a connecting rope 2 82, and two adjacent moving blocks 8 are connected by the connecting rope 1 81 and the connecting rope 2 82. When the length directions of the two adjacent moving blocks 8 are parallel to each other, the connecting rope 1 81 is parallel to the connecting rope 2 82;

[0040] like Figure 1 , Figure 2 As shown, it also includes a rotating block 41, which can be rotated by driving a second driving component 4. The second driving component 4 is a rotary electric cylinder. The rotation mode of the rotating block 41 is back and forth rotation, and the rotation angle is 92 degrees to 95 degrees.

[0041] The rotating block 41 is located on the left side of the first bracket 2. The two ends of the rotating block 41 in the length direction are connected to the leftmost moving block 8 through connecting rope 1 81 and connecting rope 2 82. When the length directions of the rotating block 41 and the moving block 8 are parallel to each other, connecting rope 1 81 and connecting rope 2 82 are parallel.

[0042] The curtain pulling method of the curtain pulling device comprises the following steps:

[0043] ① Such as Figure 4 As shown, when the width direction of the blade 5 is perpendicular to the moving direction of the blade 5, the second reel 71 is used to reel in the pull rope 2 73 and the first reel 7 is used to release the pull rope 1 72, so that the rightmost moving block 8 drives the blade 5 to move to the right together. Since the adjacent moving blocks 8 are connected by the connecting rope 1 81 and the connecting rope 2 82, each blade 5 is pulled to the right successively. When the moving block 8 moves to the right extreme position, the connecting rope 1 81 and the connecting rope 2 82 remain in a tensioned state.

[0044] ② If Figure 1 As shown, the rotating block 41 is driven to rotate by the driving component 2 4, and the rotation angle is 92 degrees to 95 degrees, so that the rotating block 41 drives the blade 5 to rotate through the connecting rope 1 81 and the connecting rope 2 82, so that the width direction of the blade 5 is parallel to the moving direction of the blade 5, and 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, so as to ensure that the width direction of the blade 5 is parallel to the moving direction of the blade 5.

[0045] ③ The blocking rod 24 moves close to the moving block 8, and the blocking rods 24 on both sides form limits on both sides of the moving direction of the moving block 8. The first reel 7 reels up the pull rope 1 72, and the second reel 71 releases the pull rope 2 73, so that the rightmost moving block 8 drives the blade 5 to move to the left together, and the raised portion 52 of the blade 5 on the right is inserted into the recessed portion 53 of the blade 5 on the left, so as to eliminate the light transmittance caused by the gap between the blades 5 and improve the light blocking property of the curtain.

[0046] ④ The second reel 71 reels in the pull rope 2 73 and the first reel 7 releases the pull rope 1 72, so that the rightmost moving block 8 drives the blade 5 to move to the right to the right extreme position, so that the raised portion 52 of the blade 5 on the right is separated from the recessed portion 53 of the blade 5 on the left, the blocking rods 24 on both sides retract, and the rotating block 41 rotates, so that the width direction of the blade 5 is perpendicular to the moving direction of the blade 5.

[0047] ⑤ The first reel 7 reels in the pull rope 1 72, and the second reel 71 releases the pull rope 2 73, and the blade 5 moves to the left and retracts.

[0048] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
