Description

Technical Field

[0001] The invention relates to the technical field of curtains, and in particular to a built-in light-shielding Venetian blind curtain. Background Art

[0002] The blinds are made by setting through holes on the blinds, passing the lifting rope fixed to the lower beam through the through holes of the blinds, and driving the lifting rope to rise or fall to achieve the lifting of the blinds; ladder ropes are arranged between the blinds of the blinds, and the rotation angle of the blinds can be adjusted by driving the ladder ropes. When the blinds are in a horizontal state, the blinds are in a fully open state; when the blinds are tilted at a certain angle to the horizontal line, the blinds are in a half-open, half-closed or closed state.

[0003] In order to block the light leakage caused by the through holes on the blinds, the Chinese invention patent with application number CN201420661347.6 discloses a blind blade and a blind, wherein the blind blade includes at least two blade holes, which are arranged on the inner side of the blade; the blind includes an upper beam track, a ladder belt, a blade, a lifting rope, a direction rope, and a lower beam track, wherein the blade is provided with a blade hole, a rope locker and a lifting rope are installed in the upper beam track, and the lifting rope passes through the upper beam track, the blade hole of the blind blade and the lower beam track in sequence, and one end of the lifting rope is fixed at the tail buckle at the bottom end of the lower beam track; the other end of the lifting rope passes through the rope locker and is connected to the rope connector from the outlet at the bottom end of the upper beam track, and the blade hole is arranged on the inner side of the blade. The blind blade does not leak light, the overlapping area between the blades is small, the cost is reduced, and the lifting rope between the blades is invisible, and the appearance is beautiful.

[0004] However, due to the offset of the blade holes, when the lifting cord drives the blinds to rise, as the blinds blades accumulate on the lower beam track, the center of gravity of the lower part of the lifting cord gradually deflects. For sunshade products built into the insulating glass, the lower beam track and the blinds blades will scratch the inner surface of the insulating glass or produce abnormal noises, and even affect the normal lifting and lowering of the blinds. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a built-in light-blocking venetian blind curtain, which has good light-blocking performance, can be smoothly lifted and lowered and turned over in a hollow glass, and has high reliability.

[0006] In order to solve the above technical problems, the present invention provides a built-in blackout venetian blind curtain, which is arranged in a hollow glass and includes a venetian blind sheet, a turning ladder rope, a lifting rope, a bracket, a flap wheel and a driving mechanism.

[0010] The driving mechanism is connected to the impeller and drives the impeller to rotate. The impeller is used to rotate and drive the venetian blinds to flip and the bracket to rise and fall.

[0011] As an improvement of the above solution, the sliding member is arranged on a side of the bracket close to the through hole of the venetian blind.

[0012] As an improvement of the above solution, the bracket is provided with a counterweight block on a side close to the through hole of the venetian blind.

[0013] As an improvement of the above solution, when the venetian blinds are flipped over to be closed, the adjacent venetian blinds completely cover the through holes.

[0014] As an improvement of the above solution, the lifting rope is in the shape of a flat belt.

[0015] As an improvement of the above solution, the through hole is elliptical or long strip-shaped extending in the length direction of the venetian blind.

[0016] As an improvement of the above solution, a receiving groove adapted to the venetian blind slat is provided on the top of the bracket, and a slot for receiving a counterweight is provided on one side of the bracket close to the through hole of the venetian blind slat.

When the driving mechanism drives the flap wheel to rotate, so that the bracket and the venetian blind sheet are lowered into place, the driving mechanism further drives the flap wheel to rotate, and when the turning ladder rope is driven by the friction of the flap wheel to flip the venetian blind sheet to a closed state, the adjacent venetian blind sheet can block the through hole, thereby achieving a good blackout effect. In addition, when the driving mechanism The impeller is driven to rotate, so that the steering ladder rope is driven by the friction of the impeller to flip and reset the venetian blinds (that is, the venetian blinds are in a horizontal state and the venetian blinds are in a fully open state), and the driving mechanism further drives the impeller to rotate, and the impeller rotates to drive the bracket and the venetian blinds to rise, and the venetian blinds are gradually stacked on the bracket.

[0026] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below with reference to the accompanying drawings.

[0027] like Figure 1-3 As shown, the present invention provides an embodiment of a built-in blackout venetian blind, which is arranged in a hollow glass, and includes a venetian blind slat 1, a turning ladder rope 2, a lifting rope 3, a bracket 4, a turning wheel 5 and a driving mechanism. The top of the turning ladder rope 2 is sleeved with the turning wheel 5, and the venetian blind slat 1 is equidistantly mounted on the turning ladder rope 2; the venetian blind slat 1 is provided with a through hole 11 offset to one side of the long side, one end of the lifting rope 3 is fixed to the turning wheel 5, and the other end passes through the through hole 11 of the venetian blind slat 1 in sequence and is connected to the bracket 4, and a sliding member 41 is provided on the bracket 4, and the sliding member 41 is used for sliding contact with the inner surface of the hollow glass; the driving mechanism is connected to the turning wheel 5 and drives the turning wheel 5 to rotate, and the turning wheel 5 is used to rotate and drive the venetian blind slat 1 to flip and the bracket 4 to lift.

[0028] In this embodiment, a through hole 11 offset to one side of the long side is provided on the venetian blind slat 1, one end of the lifting rope 3 is fixed to the flap wheel 5, and the other end passes through the through hole 11 of the venetian blind slat 1 in sequence and is connected to the bracket 4. When the driving mechanism drives the flap wheel 5 to rotate so that the bracket 4 and the venetian blind slat 1 are lowered into place, the driving mechanism further drives the flap wheel 5 to rotate, and the turning ladder rope 2 is driven by the friction of the flap wheel 5 to flip the venetian blind slat 1 to the closed state (such as Figure 1 As shown), the adjacent venetian blinds 1 can block the through hole 11 to achieve a good shading effect; in addition, when the driving mechanism drives the impeller 5 to rotate, the turning ladder rope 2 is driven by the friction of the impeller 5 to drive the venetian blinds 1 to flip and reset (that is, the venetian blinds 1 are horizontal, as shown in FIG. Figure 1 As shown, the venetian blinds are in a fully opened state), the driving mechanism further drives the impeller 5 to rotate, and the impeller 5 rotates to drive the bracket 4 and the venetian blind slats 1 to rise, and the venetian blind slats 1 are gradually stacked on the bracket 4. Since the sliding member 41 is in sliding contact with the inner surface of the insulating glass, it can be avoided that the bracket 4 shakes in the insulating glass or collides with the inner surface of the insulating glass or produces abnormal noises during the lifting process due to the change of the center of gravity, thereby ensuring the smooth flipping and lifting of the venetian blinds.

[0029] It should be noted that the long side refers to the longer side around the venetian blind slat 1 .

[0030] Specifically, a receiving groove adapted to the venetian blind slat 1 is provided at the top of the bracket 4, and a ladder rope fixing plug 42, a ladder rope fixing buckle 43 and a winding belt buckle 44 are provided in the receiving groove. The ladder rope fixing plug 42 and the ladder rope fixing buckle 43 cooperate to fix the bottom of the steering ladder rope 2, and the winding belt buckle 44 is fixed to the bottom of the lifting rope 3.

[0031] To ensure a good shading effect, when the venetian blinds 1 of this embodiment are turned over to be closed, the adjacent venetian blinds 1 completely block the through hole 11. The lifting cord 3 is preferably a flat belt-shaped roll 3, and the through hole 11 is an ellipse or a long strip extending in the length direction of the venetian blinds 1. When the impeller 5 rotates, the roll 3 is stacked on the impeller 5. Compared with the lifting cord 3 spirally wound on the rope lock, it is not easy to get knotted or misaligned. Moreover, the roll 3 passes through the through hole 11, which can also achieve a certain shading effect on the light of the through hole 11.

[0032] The sliding member 41 may be a slider. To reduce the friction between the sliding member 41 and the insulating glass, the sliding member 41 of this embodiment is preferably a roller 41. The two ends of the bracket 4 are provided with rubber plugs 45. The side of the rubber plug 45 close to the through hole 11 of the venetian blind slat 1 is provided with a roller 46, and the roller 41 is sleeved on the roller 46. The roller 41 is preferably made of plastic material. The roller 41 is preferably arranged on the side of the bracket 4 close to the through hole 11 of the venetian blind slat 1, that is, opposite to the direction of the center of gravity offset. When the impeller 5 drives the venetian blind to rise and fall, the roller 41 rolls on the surface of the insulating glass.

[0033] The bracket 4 described in this embodiment is provided with a slot on one side close to the through hole 11 of the venetian blind slat 1, and a counterweight block 7 is provided in the slot. When the driving mechanism drives the turning wheel 5 to rotate and turns the venetian blind slat 1 to a horizontal state, the bracket 4 is further driven to rise, and the venetian blind slat 1 is gradually stacked on the bracket 4. The counterweight block 7 can balance the weight of the venetian blind slat 1 with an offset center of gravity, thereby preventing the venetian blind slat 1 or the bracket 4 from being seriously tilted, and avoiding scratches or abnormal noises on the inner surface of the insulating glass, thereby ensuring smooth turning and lifting of the venetian blind.

[0034] The top of the venetian blind of this embodiment is provided with a mounting seat 8 and a cover plate 9 assembled with the mounting seat 8. The driving mechanism and the impeller 5 are arranged in the mounting seat 8. The mounting seat 8 is also provided with a wheel seat 81 for supporting the impeller 5. The driving mechanism of this embodiment specifically includes a motor 61, a hexagonal shaft 62 and a stroke controller 63. The motor 61 and the stroke controller 63 are respectively arranged at the two ends of the hexagon 62. The impeller 5 is sleeved on the hexagonal shaft 62. The motor 61 drives the hexagonal shaft 62 and the impeller 5 to rotate together. The stroke controller 63 is used to limit the number of turning circles of the hexagonal shaft 62 to limit the lifting height of the venetian blind. The stroke controller 63 can adopt a screw limiter, but is not limited to this.

[0035] In summary, the implementation of the present invention has the following beneficial effects:

[0036] 1. A through hole 11 offset to one side of the long side is provided on the venetian blind slat 1, and the adjacent venetian blind slat 1 can block the through hole 11 to achieve a good shading effect;

[0037] 2. The sliding member 41 can prevent the bracket 4 from shaking in the insulating glass or colliding with the inner surface of the insulating glass or making abnormal noises due to the change of the center of gravity during the lifting process, thereby ensuring the smooth flipping and lifting of the blinds;

[0038] 3. A counterweight is provided on the bracket 4 to balance the weight of the blind slat 1 with an offset center of gravity, thereby preventing the blind slat 1 or the bracket 4 from being seriously tilted and improving the balance of the bracket 4 when the blind is raised or lowered;

[0039] 4. The roll belt 3 passes through the offset through hole 11 on the venetian blind slat 1. When the venetian blind slat 1 is flipped to be closed, the roll belt can be hidden to achieve the best light-shielding effect and aesthetics.

[0040] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
