Variable light conditioning flexible screen

Abstract

This utility model relates to the field of curtain technology and discloses a variable light-adjustable sheer curtain. A fixed cylinder is fixedly installed on one side of the roller inside the mounting box via a fixed bracket. This utility model adjusts the light transmittance by alternating the blackout fabric and transparent fabric on the sheer curtain body, allowing the blackout fabric and transparent fabric to be misaligned or overlapped by adjusting the position of the sheer curtain body. Furthermore, the bottom counterweight strip, contact roller, rotating groove, and movable rotating column at the bottom of the sheer curtain body enable contact between the sheer curtain body and the movable rotating column during repeated stretching. This reduces the friction experienced by the sheer curtain body during counterweight application, allowing the sheer curtain body to contact the movable rotating column, which has lower friction. This reduces wear caused by repeated stretching of the sheer curtain body and improves its flexibility during stretching and lowering.

Description

Technical Field

[0001] This utility model relates to the field of curtain technology, specifically to a soft gauze curtain with variable light adjustment. Background Technology

[0002] Sheer curtains, also known as zebra blinds, light-adjusting blinds, double-layer roller blinds, day and night blinds, rainbow blinds, and soft silk blinds, are a type of curtain fabric originating in South Korea and very popular internationally. They are primarily made of polyester, linen, and nylon, and consist of two overlapping fabric pieces. Each piece is horizontally divided into alternating light-transmitting and light-blocking sections. The double-layered fabric allows for light adjustment without taking up much space, and the light can be adjusted locally. This not only meets different light needs such as blackout, partial blackout, and light transmission, but also softens strong sunlight, providing a harmonious lighting effect indoors. By slightly moving the two fabric pieces up and down, the light-transmitting and light-blocking sections overlap and stagger, adjusting the light. During the day, the angle of the curtains can be adjusted as needed, allowing different levels of light transmission to overlap and flexibly control the amount of light entering the room.

[0003] Current soft gauze curtains, due to their double-layer design, tend to sag and bend at the edges after prolonged stretching. This makes it difficult for the double-layer soft gauze curtains to achieve effective positioning during practical applications, thus affecting the actual light adjustment effect. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a variable light-adjustable soft gauze curtain, which solves the problem that after prolonged stretching and use, the double-layer structure of the soft gauze curtain causes the edges to loosen and bend, resulting in the double-layer soft gauze curtain being unable to achieve effective positional alignment in practical applications, thus affecting the actual light-adjusting effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a variable light-adjustable soft gauze curtain, comprising a soft gauze curtain body, wherein several sets of light-blocking cloths are staggered and equidistantly arranged on the soft gauze curtain body, the soft gauze curtain body is rolled up on a winding roller inside the mounting top box, the winding roller is mounted inside the mounting top box via a rotating bracket, and one end of the winding roller is connected to a winding motor via a reduction gear box; a fixed cylinder is fixedly installed on one side of the winding roller inside the mounting top box via a fixed bracket.

[0006] The bottom of the soft yarn curtain passes between the bottom counterweight and the contact roller, and the contact roller is rotatably mounted on the top of the bottom counterweight. The edge of the contact roller is evenly provided with rotating grooves along its circumference, and a movable rotating column is rotatably connected to the inner side of each rotating groove.

[0007] The side ends of the soft gauze curtain body are sewn with soft gauze curtain edging, and the edge of the soft gauze curtain edging is provided with covering magnetic blocks. The soft gauze curtain body and the soft gauze curtain edging are both raised and lowered and slid along the inner side of the metal guide side plate on both sides. The metal guide side plate is fixedly installed on the edge of the fixed bracket by a fixing frame.

[0008] The metal guide side plate is provided with two sets of limiting rails at its edge, and a rail groove is formed on the inner side of each set of limiting rails.

[0009] As a preferred technical solution of the variable light-adjustable soft gauze curtain of this utility model, the surface of the soft gauze curtain body adjacent to the light-blocking cloth is set as transparent cloth, one end of the soft gauze curtain body is fixedly connected to the fixed cylinder, and the other end is wound on the take-up roller.

[0010] As a preferred technical solution of the variable light-adjustable soft gauze curtain of this utility model, a gap is provided between the bottom counterweight bar and the contact roller, the soft gauze curtain body passes through the gap, and the soft gauze curtain body is in contact with the movable rotating column rotatably connected to the edge of the contact roller.

[0011] As a preferred technical solution of the variable light-adjustable soft gauze curtain of this utility model, the soft gauze curtain edging and the covering magnetic block on the side of the soft gauze curtain body are guided and slid along the track groove, and the covering magnetic block is attracted to the metal guide side plate by weak magnetism.

[0012] As a preferred technical solution of the variable light-adjustable soft gauze curtain of this utility model, the front edge of the mounting top box is equidistantly connected with movable columns, the outer side of the movable columns is fitted with connecting springs, one end of the movable column is provided with a disc, and the other end is connected with a rotating frame.

[0013] A rotating roller is embedded in the inner side of the end of the rotating frame, and flexible strips are evenly arranged on the edge of the rotating roller. A shielding box is provided on the outer side of the mounting top box at the position outside the movable column and the connecting spring.

[0014] As a preferred technical solution of the variable light-adjustable soft gauze curtain of this utility model, the front edge of the mounting box is provided with a movable hole, the movable column moves in the movable hole, one end of the connecting spring is connected to the edge of the mounting box, and the other end is connected to the disc.

[0015] As a preferred technical solution of the variable light-adjustable soft gauze curtain of this utility model, the rotating roller is rotatably connected to the inner side of the rotating frame through a movable shaft, and the flexible strip on the edge of the rotating roller is in close contact with the soft gauze curtain body.

[0016] Compared with the prior art, this utility model provides a variable light-adjustable soft gauze curtain, which has the following beneficial effects:

[0017] 1. By alternating the blackout fabric and transparent fabric on the soft gauze curtain, the light transmittance can be adjusted by changing the position of the soft gauze curtain so that the blackout fabric and transparent fabric are staggered or overlapped. The bottom counterweight strip, contact roller, rotating groove and movable rotating column at the bottom of the soft gauze curtain can reduce the friction suffered by the soft gauze curtain when it is repeatedly stretched and moved by contacting the soft gauze curtain with the movable rotating column. This reduces the wear caused by repeated stretching of the soft gauze curtain and improves its flexibility when stretching and lifting.

[0018] The flexible gauze curtain utilizes metal guide side plates, fixing frames, limiting tracks, and track grooves along its sides to guide and slide along the track grooves during its raising and lowering movements. This allows for precise control over the curtain's position. Combined with the gauze curtain's edging and covering magnetic blocks on its sides, the covering magnetic blocks use weak magnetism to attract the metal guide side plates. This maintains the flatness of the curtain's sides after it reaches the designated position without affecting its flexible raising and lowering, thus preventing bending and sagging and ensuring the effective dimming of the curtain.

[0019] 2. By using the fixed cylinder, when the winding roller winds up the soft yarn curtain, the soft yarn curtain comes into contact with the arc surface of the fixed cylinder, which facilitates guidance during the winding of the soft yarn curtain. With the help of the movable column, connecting spring and disc, the rotating frame can be supported in an elastic way, so that the rotating roller and flexible strip on the inner side of the rotating frame can come into contact with the soft yarn curtain under its support. Through the constraint between the rotating roller and the fixed cylinder, the soft yarn curtain can be in close contact with the flexible strip under pressure, thereby achieving a smoothing treatment when the soft yarn curtain is wound up, avoiding wrinkles and deformation of the soft yarn curtain after long-term use.

[0032] Example: Please refer to Figure 1-7 This utility model provides the following technical solution: a variable light-adjustable soft gauze curtain, including a soft gauze curtain body 1, several sets of light-blocking cloths 2 are staggered and equidistantly arranged on the soft gauze curtain body 1, the soft gauze curtain body 1 is wound on a winding roller 4 inside the mounting top box 3, the winding roller 4 is mounted inside the mounting top box 3 through a rotating bracket, and one end of the winding roller 4 is connected to a winding motor 5 through a reduction gear box, a fixing cylinder 6 is fixedly installed on one side of the winding roller 4 inside the mounting top box 3 through a fixing bracket, the surface of the soft gauze curtain body 1 adjacent to the light-blocking cloth 2 is set as transparent cloth, one end of the soft gauze curtain body 1 is fixedly connected to the fixing cylinder 6, and the other end is wound on the winding roller 4, so that the light transmittance can be adjusted by the staggered arrangement of the light-blocking cloth 2 and the transparent cloth on the soft gauze curtain body 1, and by adjusting the position of the soft gauze curtain body 1, so that the light-blocking cloth 2 and the transparent cloth are staggered or overlapped, and the winding and unwinding of the soft gauze curtain body 1 is convenient;

[0033] The bottom of the soft yarn curtain 1 passes between the bottom counterweight 7 and the contact roller 8, and the contact roller 8 is rotatably mounted on the top of the bottom counterweight 7. The edge of the contact roller 8 is evenly provided with rotating grooves 9 along its circumference. The inner side of each rotating groove 9 is rotatably connected to a movable rotating column 10. A gap is provided between the bottom counterweight 7 and the contact roller 8. The soft yarn curtain 1 passes through the gap and is in contact with the movable rotating column 10 rotatably connected to the edge of the contact roller 8. By making contact between the soft yarn curtain 1 and the movable rotating column 10, the friction suffered by the soft yarn curtain 1 when the bottom counterweight 7 is counterweighted is reduced, so that the soft yarn curtain 1 can contact the movable rotating column 10 with less friction.

[0034] The side end of the soft gauze curtain body 1 is sewn with a soft gauze curtain edging 11, and the edge of the soft gauze curtain edging 11 is provided with a covering magnetic block 12. The soft gauze curtain body 1 and the soft gauze curtain edging 11 both slide up and down along the inner side of the metal guide side plate 13 on both sides. The metal guide side plate 13 is fixedly installed on the edge of the fixed bracket by the fixed frame 14.

[0035] Two sets of limiting tracks 15 are provided at the edge of the metal guide side plate 13. Each set of limiting tracks 15 has a track groove 16 formed on the inner side. The soft gauze curtain edging 11 and the covering magnetic block 12 on the side of the soft gauze curtain 1 are guided and slid along the track groove 16. The covering magnetic block 12 and the metal guide side plate 13 are attracted by weak magnetism. The covering magnetic block 12 is attracted to the side wall of the metal guide side plate 13 by weak magnetism. While not affecting the flexible raising and lowering of the soft gauze curtain 1, the flatness of the side of the soft gauze curtain 1 is maintained by the attraction of weak magnetism after the soft gauze curtain 1 is raised and lowered to the specified position.

[0036] Movable columns 17 are equidistantly connected to the front edge of the mounting box 3. A connecting spring 18 is sleeved on the outside of the movable column 17. A disc 19 is provided at one end of the movable column 17, and a rotating frame 20 is connected to the other end. A movable hole is opened at the front edge of the mounting box 3, and the movable column 17 moves in the movable hole. One end of the connecting spring 18 is connected to the edge of the mounting box 3, and the other end is connected to the disc 19, so that the movable column 17 can be installed movably and the connecting spring 18 can be connected. The rotating frame 20 can be supported in an elastic way.

[0037] A rotating roller 21 is rotatably connected to the inner side of the end of the rotating frame 20, and flexible strips 22 are evenly arranged on the edge of the rotating roller 21. The rotating roller 21 is rotatably connected to the inner side of the rotating frame 20 through a movable shaft, and the flexible strips 22 on the edge of the rotating roller 21 are in close contact with the soft yarn curtain 1, so that the rotating roller 21 and flexible strips 22 on the inner side of the rotating frame 20 can contact the soft yarn curtain 1 under its support. A shielding box 23 is provided at the outer side of the mounting top box 3, located outside the movable column 17 and the connecting spring 18.

[0038] The working principle and usage process of this utility model are as follows: In actual application, by interlacing the light-blocking cloth 2 and the transparent cloth on the soft gauze curtain 1, the position of the soft gauze curtain 1 is adjusted so that the light-blocking cloth 2 and the transparent cloth are misaligned or overlapped to adjust the light transmittance. During the position adjustment of the soft gauze curtain 1, the winding motor 5 drives the winding roller 4 to rotate. The output power of the winding motor 5 is transmitted to the winding roller 4 through the reduction gear box to ensure the stable rotation of the winding roller 4. One end of the soft gauze curtain 1 is fixedly connected to the fixed cylinder 6, and the other end is wound around the winding roller 4, so that the soft gauze curtain 1 can be easily wound and unwound after the winding roller 4 rotates.

[0039] During the stretching and lifting process of the soft gauze curtain 1, the soft gauze curtain 1 comes into contact with the movable rotating column 10, thereby reducing the friction suffered by the soft gauze curtain 1 when the bottom counterweight 7 is used for counterweighting. This allows the soft gauze curtain 1 to come into contact with the movable rotating column 10, which has a smaller friction force, thereby reducing the wear caused by repeated stretching of the soft gauze curtain 1 and improving its flexibility during stretching and lifting. At the same time, when the soft gauze curtain 1 is lifted and lowered, the side of the soft gauze curtain 1 slides along the track groove 16, which facilitates the restriction of the lifting and lowering position of the soft gauze curtain 1.

[0040] Combining the soft gauze curtain edging 11 and the covering magnetic block 12 on the side of the soft gauze curtain body 1, the covering magnetic block 12 uses weak magnetism to attract the side wall of the metal guide side plate 13. While not affecting the flexible raising and lowering of the soft gauze curtain body 1, after the soft gauze curtain body 1 is raised and lowered to the specified position, the weak magnetic attraction maintains the flatness of the side of the soft gauze curtain body 1, thereby avoiding the bending and sagging of the side of the soft gauze curtain body 1 and ensuring the actual dimming effect of the soft gauze curtain body 1.

[0041] Furthermore, during the stretching and lifting of the soft yarn curtain 1, when the soft yarn curtain 1 is wound up by the fixed cylinder 6 and the winding roller 4, the soft yarn curtain 1 comes into contact with the arc surface of the fixed cylinder 6, which facilitates guidance when the soft yarn curtain 1 is wound up. With the help of the movable column 17, the connecting spring 18 and the disc 19, the rotating frame 20 can be supported in an elastic way, so that the rotating roller 21 and the flexible strip 22 on the inner side of the rotating frame 20 can come into contact with the soft yarn curtain 1 under its support.

[0042] By utilizing the constraint between the rotating roller 21 and the fixed cylinder 6, the flexible yarn curtain 1 can be in close contact with the flexible strip 22 under pressure, thereby achieving a smoothing process when the flexible yarn curtain 1 is rolled up, preventing wrinkles and deformation of the flexible yarn curtain 1 after long-term use.

[0043] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
