[0029] Example

[0030] Please see Figure 1-6 This utility model provides a technical solution: a light-transmitting and heat-insulating liftable curtain, including a support frame 1, which consists of a long back plate and two side plates. The two side plates are bolted to both ends of the long back plate to facilitate the disassembly and installation of the support frame 1; an installation component, which is set at both ends of the support frame 1 and is used to fix the support frame 1; and a limiting component, which is set at both ends of the support frame 1. A lifting component is provided on the inner side of the support frame 1.

[0031] By setting up the installation components, the support frame 1 can be centered, improving aesthetics and preventing it from loosening. The installation components include two square guide posts 9, two top plates 10, and a screw rod 11. The two square guide posts 9 pass through both ends of the support frame 1, and the two top plates 10 are fixedly connected to opposite ends of the two square guide posts 9. The two ends of the screw rod 11 are threaded to opposite ends of the two square guide posts 9. A worm gear 12 is fixedly sleeved on the outer side of the screw rod 11, and two fixing blocks 13 are fixedly connected to the inner side of the support frame 1. A worm gear 14 is rotatably connected between the two fixing blocks 13. The bottom end of the worm 14 is provided with a hexagonal groove 15, and the two ends of the lead screw 11 are provided with opposite threaded sections. The worm 14 is engaged with the outside of the worm wheel 12. By inserting an Allen wrench into the interior of the hexagonal groove 15, the Allen wrench drives the worm 14 to rotate. The worm 14 drives the worm wheel 12 to rotate, and the worm wheel 12 drives the lead screw 11 to rotate inside the square guide post 9. This causes the lead screw 11 to drive the top plate 10 on the square guide post 9 to abut against the inside of the window, thus completing the fixation of the support frame 1. At the same time, the roller blind 3 is in a centered state. Furthermore, the worm 14 and the worm wheel 12 have a self-locking effect, which can prevent the support frame 1 from loosening.

[0032] The roller blind 3 can be raised and lowered by setting up a lifting assembly. The lifting assembly includes a rotating roller 2 and a roller blind 3. The rotating roller 2 is located inside the support frame 1, and the roller blind 3 is installed on the outside of the rotating roller 2. A fixing plate 4 is fixedly connected to the inside of the rotating roller 2. The output shaft of the drive motor 6 is installed on one side of the fixing plate 4. A rotating ring 5 is rotatably connected inside the rotating roller 2. The rotating ring 5 is fixedly sleeved on the outside of the drive motor 6. A first fixing shaft 7 is fixedly connected to one end of the drive motor 6. One end of the first fixing shaft 7 passes through one end of the inner side of the support frame 1. A second fixing shaft 8 is rotatably connected to one end of the rotating roller 2. One end of the second fixing shaft 8 passes through the other end of the inner side of the support frame 1. The output shaft of the drive motor 6 drives the rotating roller 2 to rotate forward and backward through the fixing plate 4. The rotating roller 2 rolls up and unrolls the roller blind 3, thereby completing the raising and lowering of the roller blind 3.

[0033] To facilitate the disassembly and cleaning of the roller shutter 3, the limiting assembly includes two connecting blocks 17, two limiting posts 18, and a cover 19. The two connecting blocks 17 are fixedly connected to both ends of the outer side of the support frame 1. The two limiting posts 18 pass through one side of each of the two connecting blocks 17. The cover 19 is sleeved on the outer side of the limiting posts 18. A tension spring 20 is movably sleeved on the outer side of each limiting post 18. One end of the tension spring 20 is fixedly connected to one side of the connecting block 17, and the other end is fixedly connected to the inner side of the cover 19. The first fixed shaft 7... Limiting grooves 16 are provided on the outer side of the second fixed shaft 8, and two limiting posts 18 are respectively inserted into the two limiting grooves 16. By rotating the worm gear 14, the worm wheel 12 is driven to rotate. The worm wheel 12 drives the square guide post 9 to disengage from both ends of the support frame 1 through the lead screw 11. Then, the bolts at both ends of the support frame 1 are removed to facilitate the separation of the rear plate of the support frame 1 from the two side plates. Then, by pulling the cover 19, one end of the limiting post 18 is moved, and one end of the limiting post 18 disengages from the inside of the limiting groove 16, thus completing the disassembly of the side plate.

[0034] The roller blind 3 achieves light transmission and heat insulation through the arrangement of the base layer 31, photochromic coating 32, and reflective coating 33. The roller blind 3 includes the base layer 31, photochromic coating 32, and reflective coating 33. The reflective coating 33 is located on the outside of the base layer 31, and the photochromic coating 32 is located on the outside of the reflective coating 33. The base layer 31 is a blend of glass fiber and high-transmittance polyester, with the longitudinal knitting density gradually changing from 120 stitches / 10cm at the top to 280 stitches / 10cm at the bottom. The light transmittance smoothly transitions from 85% to 40% from top to bottom, resulting in a more uniform distribution of natural light. The photochromic coating 32 is a photochromic polyurethane film with a thickness of 0.05mm, containing spiropyran derivatives. The reflective coating 33 is a nano-indium tin oxide coating with a thickness of 80nm, capable of reflecting infrared rays and blocking ultraviolet rays.

[0035] The working principle or structural principle is as follows: When the support frame 1 needs to be installed, it is placed inside the window. Then, an Allen wrench is inserted into the hexagonal groove 15, which drives the worm gear 14 to rotate. The worm gear 14 drives the worm wheel 12 to rotate, and the worm wheel 12 drives the lead screw 11 to rotate inside the square guide post 9. This causes the lead screw 11 to drive the top plate 10 on the square guide post 9 to abut against the inside of the window, thus fixing the support frame 1. At the same time, the roller blind 3 is centered, improving the aesthetics of the roller blind 3 installation. Furthermore, the worm gear 14 and worm wheel 12 have a self-locking effect, which can prevent the support frame 1 from loosening. When the roller blind 3 needs to be raised or lowered, the drive motor 6 is started by controlling the switch group. The output shaft of the drive motor 6 drives the rotating roller 2 to rotate forward and backward through the fixing plate 4. The rotating roller 2 rolls up and unrolls the roller blind 3, thus completing the raising and lowering of the roller blind 3.

[0036] When it is necessary to disassemble and assemble the roller 2, the worm gear 14 is rotated to drive the worm wheel 12 to rotate. The worm wheel 12 drives the square guide post 9 to disengage from both ends of the support frame 1 through the lead screw 11. Then, the bolts at both ends of the support frame 1 are removed to facilitate the separation of the back plate of the support frame 1 from the two side plates. Then, by pulling the cover 19, one end of the limiting post 18 is moved. One end of the limiting post 18 disengages from the inside of the limiting groove 16, thus completing the disassembly of the side plate, so as to facilitate the disassembly and cleaning of the roller shutter 3.
