[0034] See also Figure 1-6 The utility model provides a technical solution: a device capable of adjusting light transmittance, comprising a light-isolating film 1 installed on a side of a window facing indoors or outdoors, wherein the light-isolating film 1 is flexible.

[0035] In this solution, the light-isolating film 1 covers the transparent surface of the window and is in a stretched state. The light-isolating film 1 can be made of: a polyvinyl chloride (PVC) flexible film, and its light-isolating effect can be enhanced by adding pigments or sunscreens;

[0036] During use, by stretching the light-isolating film 1, when the film is stretched, the thickness of the light-isolating film 1 will decrease accordingly, because the volume of the material remains essentially unchanged during the stretching process (ignoring the volume change caused by slight elastic and plastic deformation). When the light-isolating film 1 becomes thinner, the path difference of the reflected light waves is more likely to meet the conditions for destructive interference, thereby increasing light transmittance.

[0037] When using the light-transmittance-adjustable device of the present invention, the light-isolating film 1 is stretched to reduce its thickness, thereby increasing its light transmittance. During the day, users can stretch the film to varying degrees to reduce light intensity while maintaining a suitable brightness indoors. The flexibility of the present invention can reduce resource waste to a certain extent.

[0038] In this embodiment, the lower end of the light-isolating film 1 is fixedly connected to the window, and the upper end is connected to a winding mechanism. The winding mechanism includes a rotating rod 2 whose end rotates with the window. The top surface of the light-isolating film 1 is connected to the arc surface of the rotating rod 2.

[0039] When the light-isolating film 1 is in a stretched state, the top surface is connected to the arc surface on one side of the rotating rod 2 .

[0040] During specific use, the user rotates the rotating rod 2 according to the required light intensity. When rotating clockwise, the rotating rod 2 wraps around the light-isolating film 1, causing the light-isolating film 1 to be stretched as a whole, thereby making the light-isolating film 1 thinner. The light-isolating film 1 can be restored by rotating it in the opposite direction.

[0041] In this embodiment, the winding mechanism includes a torsion spring 201 installed at the end of the rotating rod 2 , and the end of the rotating rod 2 is rotated with the window through the torsion spring 201 .

[0042] When the torsion spring 201 is naturally stretched, the rotating rod 2 keeps rotating counterclockwise, so that the light-isolating film 1 remains stretched.

[0043] During specific use, when the rotating rod 2 rotates clockwise, the torsion spring 201 contacts the inside of the window, causing the torsion spring 201 to be squeezed and elastically store force.

[0044] In this embodiment, the winding mechanism further includes a draw line 3 , which is wound around the rotating rod 2 . One end of the draw line 3 is connected to the rotating rod 2 , and the other end extends toward the indoor direction.

[0045] The upper part of the draw line 3 is wound around the rotating rod 2, and the lower part is exposed on the side of the window facing the room, so that the user can use it easily.

[0046] During use, the user pulls the drawstring 3, which is wound around the rotating rod 2, causing the rotating rod 2 to rotate clockwise under the influence of the user's pulling. When the drawstring 3 loses its external force, the torsion spring 201 releases its elastic force, driving the rotating rod 2 to restore. At the same time, during the process of the rotating rod 2 rotating and restoring, the pulled part of the drawstring 3 is wound back onto the surface of the rotating rod 2.

[0047] In this embodiment, a clamping block 301 is provided at one end of the drawing wire 3 away from the rotating rod 2 , and the diameter of the clamping block 301 is larger than the diameter of the drawing wire 3 ;

[0048] The window is further provided with a fixing block 4 , one end of which is connected to the window, and the other end of which is provided with a fixing groove 401 , the width of which is larger than the diameter of the draw line 3 and smaller than the diameter of the clamping block 301 .

[0049] During specific use, after the user pulls out the drawing line 3, the user pulls the drawing line 3 so that the top surface of the clamping block 301 is located below the bottom surface of the fixing block 4, and then moves the drawing line 3 toward the fixing groove 401 so that the clamping block 301 is located directly below the fixing block 4. Then, the drawing line 3 is gradually released. Under the action of the torsion spring 201, the rotating rod 2 gradually retracts the drawing line 3. During this process, the top surface of the clamping block 301 gradually moves toward the bottom surface of the fixing block 4 until the two are at odds with each other. Then, the clamping block 301 and the fixing block 4 cooperate to fix the drawing line 3, so that the light-isolating film 1 remains in a stretched state.

[0050] When the clamping block 301 and the fixed block 4 are against each other, the clamping block 301 is subjected to an upward pulling force, which, combined with the friction between the clamping block 301 and the fixed block 4, makes it difficult for the clamping block 301 and the drawing wire 3 to move left and right, and thus it is difficult for the drawing wire 3 to move left and right in a natural state and fall out of the fixed groove 401.

[0051] When the light-isolating film 1 needs to be restored, the user can simply pull the wire 3 out of the fixing groove 401.

[0052] In this embodiment, a plurality of the fixing blocks 4 are arranged along the height direction of the window, and the distance between the upper and lower adjacent fixing blocks 4 is greater than the height of the clamping block 301 .

[0053] During specific use, the user stretches the drawing wire 3 to different degrees according to the required indoor light intensity, so as to enable the light-isolating film 1 to maintain different degrees of thickness as the drawing wire 3 is stretched to different degrees, and then engages the drawing wire 3 and the clamping block 301 with the fixed blocks 4 at different positions to maintain the state of the drawing wire 3 and the light-isolating film 1.

[0054] A window using a device capable of adjusting light transmittance comprises the device, a window frame 5 and two transparent plates 501 installed in the window frame 5 , wherein the light-isolating film 1 is located between the two transparent plates 501 .

[0055] In this embodiment, an elastic connector connected to the side of the light-isolating film 1 is provided on the inner side of the window frame 5 , and the elastic connector is connected to the inner side of the window frame 5 and the light-isolating film 1 respectively.

[0056] When the light-isolating film 1 is in a stretched state, the elastic connector is in a naturally stretched state, and the elastic connector is a tensile elastic structure;

[0057] During specific use, when the light-isolating film 1 is stretched and deformed, the two sides are connected to the window frame 5 through elastic connectors. Under the action of tensile elasticity, the light-isolating film 1 is stretched and deformed. Under the action of tensile force, the two sides are not easy to sink inward due to stress, thereby reducing the situation where the light-isolating film 1 cannot completely cover the transparent plate 501 due to the sinking of the two sides when being stretched.

[0058] In this embodiment, the elastic connecting member includes a vertical rod 6, a spring 601 and two sliding members. The two sliding members are respectively located at the upper and lower ends of the vertical rod 6, and both of the sliding members are slidably engaged with the vertical rod 6. The spring 601 is sleeved on the vertical rod 6 and located between the two sliding members. The two ends of the spring 601 are respectively against the two sliding members.

[0059] The two sliding members are connected to one side of the light-isolating film 1 .

[0060] Among them, when the spring 601 is in a naturally stretched state, it pushes the two sliding parts in opposite directions. Since the sliding parts slide with the light-isolating film 1 and the vertical rod 6 respectively, when the light-isolating film 1 is stretched and deformed, the sliding parts can move along with the stretching of the light-isolating film 1.

[0061] During specific use, when the light-isolating film 1 is stretched and deformed, the concave force on both sides pulls the two sliding parts closer together. Since the spring 601 is located between the two sliding parts, the elasticity of the spring 601 relieves part of the concave force, making it difficult for the two sides of the light-isolating film 1 to be concave due to stretching and deformation.

[0062] In this embodiment, the sliding member includes a slider 7, a connecting rod 701 and a hinge 702. The hinge 702 is connected to one side of the light-isolating film 1. The two ends of the connecting rod 701 are respectively hinged to the hinge 702 and the slider 7. The slider 7 slides with the vertical rod 6.

[0063] When the light-isolating film 1 is in a straight state, the two connecting rods 701 are in an inclined state. Figure 5 、 6 .

[0064] During specific use, when the side of the light-isolating film 1 is concave inward, it will drive the two hinges 702 to move synchronously in the same direction, that is, move in the direction away from the slider 7. During this process, one end of the connecting rod 701 is hinged to the hinge 702, which prompts the connecting rod 701 to have a tendency to move away from the slider 7, and then the two sliders 7 are driven to move toward each other through the two connecting rods 701, prompting the two sliders 7 to squeeze the upper and lower ends of the spring 601 respectively. Under the elastic action of the spring 601, the force of the concave light-isolating film 1 is relieved, so that the side of the light-isolating film 1 is not easy to be concave.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
