[0005] The utility model aims to provide an anti-ultraviolet curtain fabric to solve the problem in the background art that in the field of household curtains, curtains usually made of a single fabric will limit indoor lighting and the effect of absorbing sunlight warmth.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an anti-ultraviolet curtain fabric, comprising a supporting crossbar, a light-transmitting curtain, and a light-blocking curtain, wherein the supporting crossbar is composed of two identical slide rails, and the light-transmitting curtain and the light-blocking curtain are respectively located at the bottom of the supporting crossbar;

[0007] The top of the light-transmitting curtain and the light-blocking curtain are both provided with a plurality of light-blocking curtains distributed at equal intervals, and a fixed slider is nested inside the connecting ring, and a pulley is rotatably connected inside the upper end of the fixed slider, the fixed slider is located at the leftmost end inside the supporting crossbar and is fixedly connected to the inside of the supporting crossbar, and the top of the fixed slider is located at the rightmost end inside the supporting crossbar and is fixedly connected to a motion shaft;

[0008] The top of the support crossbar is provided with two symmetrically distributed slide grooves, and the top of the right end of the support crossbar is fixedly connected to two fixed shafts, and the outer sides of the two fixed shafts are rotatably connected to fixed wheels, the left end of the top of the support crossbar is fixedly connected to two fixed blocks A, and the right end of the support crossbar is fixedly connected to two fixed blocks B, the left end of the support crossbar is fixedly connected to two pad blocks, and an adjustment structure is provided on one side of the inner side of the left end of the support crossbar;

[0009] The adjustment structure is provided with a fixing part, and has two rotating cylinders connected to the inside for rotation. A slot is provided in the middle of the rotating cylinder, and symmetrically distributed reels are provided at both ends of the rotating cylinder. An adjusting rope is wound around the outside of the reel, and the adjusting rope forms a winding knot A on the outside of the reel. The two ends of the adjusting rope are respectively fixedly connected to the reel and the fixed block A. A driving rope is wound around the outside of the other reel, and the driving rope is bent at the top of the raising block, and the driving rope forms a winding knot B on the outside of the reel. The two ends of the driving rope are respectively fixedly connected to the fixed block B and the reel.

[0010] Furthermore, the interior of the slide rail is configured as a T-shaped structure, and the interior of the slide rail is engaged with the T-shaped structure formed between the fixed slider and the moving shaft.

[0011] Furthermore, the motion shaft is slidably connected to the inside of the slide groove.

[0012] Furthermore, a moving wheel is rotatably connected to the outer side of the moving shaft, and the outer side of the moving wheel is simultaneously rotatably connected to the adjusting rope and the driving rope, and the adjusting rope and the moving wheel form a bend A on the outer side of the moving wheel.

[0013] Furthermore, a bend A is rotatably connected to the outer side of the fixed wheel, and the bend A forms a bend B on the outer side of the fixed wheel.

[0014] Furthermore, the light-transmitting curtain is made of a transparent material.

[0015] Furthermore, the blackout curtain is configured as a woven structure.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] The anti-ultraviolet curtain is provided with a light-transmitting curtain and a light-blocking curtain. When the light-transmitting curtain is in a closed state and the light-blocking curtain is in an open state, sunlight can penetrate the light-transmitting curtain and enter the room. Since the light-transmitting curtain is made of polyvinyl chloride, these materials can effectively filter the ultraviolet rays in the sunlight. This prevents ultraviolet damage while ensuring sufficient light and warmth in the room. When it is necessary to maintain indoor privacy, the light-blocking curtain can be closed to block the light from entering.

[0018] Furthermore, an adjustment structure is provided. When the curtain is closed, the user operates the adjustment rope to move, which will drive the rotating drum to rotate. As the adjustment rope drives the rotating drum to rotate in the direction of rotation, the adjustment rope will be wound around the outside of the reel, and the winding knot B will gradually untie outside the reel. When the adjustment rope is wound around the outside of the reel to form a winding knot A, the overall extension length of the adjustment rope will be shortened accordingly. This change causes the adjustment rope to move toward the left end of the supporting cross bar through the driving rod moving wheel at the bend A. Subsequently, the moving wheel drives the moving shaft to slide inside the slide groove, and at the same time, the fixed slider at the bottom of the moving shaft slides inside the supporting cross bar. This series of actions also causes the pulley to rotate inside the supporting cross bar. As multiple fixed sliders approach each other, they will fold the light-transmitting curtain or the light-blocking curtain, so that the curtain reaches the open state.

[0019] Furthermore, conversely, when the adjusting rope drives the rotating drum to wind the winding knot B to the outside of the reel in a specific rotation direction, the adjusting rope will automatically untie on the outside of the reel. During this process, the driving rope will form a bend A at the moving wheel and a bend B on the outside of the fixed wheel. Since the driving rope is wound around the outside of the reel to form the winding knot B, the overall extension length of the driving rope will be shortened. Subsequently, the driving rope changes its angle to 180° through the fixed wheel, so that the driving rope drives the moving wheel to move toward the right end of the supporting cross bar under the restriction of the fixed shaft. This process further prompts the moving shaft to drive the fixed slider and the pulley to slide to the right end inside the supporting cross bar, thereby finally realizing the closed state of the curtain.

[0028] In a further preferred embodiment of the present invention, Figure 1 - Figure 6As shown, the tops of the light-transmitting curtain 2 and the blackout curtain 3 are each provided with a plurality of equally spaced blackout curtains 3, and a fixed slider 5 is nested inside the connecting ring 4, and a pulley 6 is rotatably connected to the upper end of the fixed slider 5, the fixed slider 5 is located at the leftmost end inside the supporting crossbar 1 and is fixedly connected to the supporting crossbar 1, and the fixed slider 5 is located at the top of the rightmost end inside the supporting crossbar 1 and is fixedly connected to a moving shaft 7; two symmetrically distributed slide grooves 8 are provided on the top of the supporting crossbar 1, and two fixed shafts 9 are fixedly connected to the top of the right end of the supporting crossbar 1, and the outer sides of the two fixed shafts 9 are rotatably connected to fixed wheels 10, two fixed blocks A11 are fixedly connected to the left end of the top of the supporting crossbar 1, and two fixed blocks B12 are fixedly connected to the right end of the supporting crossbar 1, two heightening blocks 13 are fixedly connected to the left end of the supporting crossbar 1, and an adjustment structure is provided on one side of the left end of the supporting crossbar 1; the adjustment structure is provided with a fixing part 14, and two rotating cylinders 15 are rotatably connected inside, a slot 16 is provided in the middle of the rotating cylinder 15, and symmetrically distributed reels 17 are provided at both ends of the rotating cylinder 15, An adjusting rope 18 is wound around the outside of the reel 17, and the adjusting rope 18 forms a winding knot A19 on the outside of the reel 17, and the two ends of the adjusting rope 18 are fixedly connected to the reel 17 and the fixed block A11 respectively, and a driving rope 21 is wound around the outside of the other reel 17, and the driving rope 21 is bent at the top of the padding block 13, and the driving rope 21 forms a winding knot B22 on the outside of the reel 17, and the two ends of the driving rope 21 are fixedly connected to the fixed block B12 and the reel 17 respectively, and the interior of the slide rail is set as a T-shaped structure, and the interior of the slide rail is connected to the fixed slider 5 and The T-shaped structures formed between the moving shafts 7 are mutually engaged, the moving shaft 7 is slidably connected to the inside of the slide groove 8, the outer side of the moving shaft 7 is rotatably connected to the moving wheel 24, and the outer side of the moving wheel 24 is rotatably connected to the adjusting rope 18 and the driving rope 21 at the same time, and the adjusting rope 18 and the moving wheel 24 form a bend A20 on the outer side of the moving wheel 24, the outer side of the fixed wheel 10 is rotatably connected to the bend A20, and the bend A20 forms a bend B23 on the outer side of the fixed wheel 10, the light-transmitting curtain 2 is set to a transparent material, and the light-blocking curtain 3 is set to a woven structure;

[0029] When the light-transmitting curtain 2 is in the closed state and the blackout curtain 3 is in the open state, sunlight can penetrate the light-transmitting curtain 2 and enter the room. Since the light-transmitting curtain 2 is made of polyvinyl chloride, these materials can effectively filter the ultraviolet rays in the sunlight. This prevents ultraviolet damage while ensuring sufficient light and warmth in the room. When it is necessary to maintain indoor privacy, the blackout curtain 3 can be closed to block the light from entering;

[0030] When the curtain is closed, the user operates the adjusting rope 18 to move, which will drive the rotating drum 15 to rotate. As the adjusting rope 18 drives the rotating drum 15 to rotate in the direction of rotation, the adjusting rope 18 will be wound around the outside of the reel 17, and the winding knot B22 will gradually untie outside the reel 17. When the adjusting rope 18 is wound around the outside of the reel 17 to form the winding knot A19, the overall extension length of the adjusting rope 18 will be shortened accordingly. This change causes the adjusting rope 18 to move toward the left end of the supporting cross bar 1 through the driving rod moving wheel 24 at the bend A20. Subsequently, the moving wheel 24 drives the moving shaft 7 to slide inside the slide groove 8, and at the same time makes the fixed slider 5 at the bottom of the moving shaft 7 slide inside the supporting cross bar 1. This series of actions also makes the pulley 6 rotate inside the supporting cross bar 1. As the multiple fixed sliders 5 approach each other, they will fold the light-transmitting curtain 2 or the blackout curtain 3, so that the curtain reaches the open state.

[0031] Conversely, when the adjusting rope 18 drives the rotating drum 15 to wind the winding knot B22 to the outside of the reel 17 in a specific rotation direction, the adjusting rope 18 will automatically untie on the outside of the reel 17. During this process, the driving rope 21 will form a bend A20 at the moving wheel 24 and a bend B23 on the outside of the fixed wheel 10. Since the driving rope 21 is wound around the outside of the reel 17 to form the winding knot B22, the overall extension length of the driving rope 21 will be shortened. Subsequently, the driving rope 21 changes its angle to 180° through the fixed wheel 10, so that the driving rope 21 drives the moving wheel 24 to move toward the right end of the supporting cross bar 1 under the restriction of the fixed shaft 9. This process further prompts the moving shaft 7 to drive the fixed slider 5 and the pulley 6 to slide to the right end inside the supporting cross bar 1, thereby finally realizing the closed state of the curtain.
