Description

Technical Field

[0001] The utility model relates to the field of rolling curtains, in particular to a multi-layer dimming zebra curtain. Background Art

[0002] Roller blinds are window decoration products installed on windows for shading. The curtain fabric is processed with resin, rolled into a roller shape, and raised and lowered with a pull rope or chain. It has the advantages of simple operation and beautiful appearance. Zebra blinds, also known as translucent blinds, are a type of curtain fabric. Zebra blinds have blackout fabric and translucent fabric. The blackout fabric and translucent fabric are arranged alternately, which can make the window frame look clean and neat, and make the whole room look spacious and simple.

[0003] The disadvantage of existing roller blinds is that when zebra blinds are used as sunshades, the shading and light transmission effects of the blinds are not very prominent. The reason is that the light transmittance of traditional sunshades is low and the range of light brightness that can be adjusted is small, which needs to be improved. Utility Model Content

[0004] The utility model aims to provide a multi-layer dimming zebra curtain with soft light, good light blocking and light transmission effects in view of the above problems.

[0005] To achieve the above purpose, the utility model discloses a multi-layer dimming zebra curtain, including a rolling curtain box, in which a rolling curtain tube is rotatably installed. Its structural characteristics are: a curtain cloth is wound on the rolling curtain tube, the curtain cloth is a zebra curtain, the curtain cloth is provided with three layers, the upper ends of the three layers of curtain cloth are fixed on the rolling curtain tube, the upper ends of the three layers of curtain cloth are spaced apart from each other on the rolling curtain tube, and when the curtain cloth falls to a low height, the light-transmitting cloths of the three layers of curtain cloth overlap each other.

[0006] After adopting the above structure, since the blackout cloth of the traditional sunshade must be larger than the translucent cloth to achieve the blackout effect, the upper and lower heights of the blackout cloth of this product are smaller than the translucent cloth. When the three layers of blackout cloth overlap, the translucent part can be larger than the blackout part, a larger lighting range can be obtained, and the adjustable light brightness range is larger.

[0007] In order to improve the shading effect of the three-layer curtain, a stop edge for pushing the three-layer curtain to fit each other is provided on the rolling curtain tube.

[0008] Regarding the specific position of the retaining edge, the retaining edge is located at the lower part of the rolling shutter box.

[0009] In order to prevent light leakage from the curtain in the shading state, the upper and lower heights of the shading portion are smaller than the upper and lower heights of the light-transmitting fabric.

[0010] Regarding the arrangement of the three-layer curtain fabric, the curtain fabric includes a first curtain fabric, a second curtain fabric and a third curtain fabric, and the structures of the first curtain fabric, the second curtain fabric and the third curtain fabric are all the same.

[0011] Regarding the arrangement structure of the three-layer cord, the second cord is located between the first cord and the third cord.

[0012] In order to enhance the wind resistance of the curtain, a lower beam is installed at the lower ends of the first curtain and the second curtain, and the lower beam extends along the width direction of the curtain.

[0013] Regarding the arrangement structure of the lower beam, the lower end of the third curtain is installed with the lower beam, and the lower beam extends along the width direction of the curtain.

[0014] Regarding the connection structure between the rolling curtain tube and the three-layer curtain cloth, three mounting grooves are arranged on the side wall of the rolling curtain tube, and the upper ends of the three-layer curtain cloth are fixedly mounted in the three mounting grooves respectively.

[0015] Preferably, the three mounting grooves extend transversely, and the three mounting grooves are arranged parallel to each other and spaced apart.

[0016] To sum up, the beneficial effect of the utility model is that the blackout cloth of the traditional sunshade must be larger than the light-transmitting cloth to achieve the shading effect, while the upper and lower heights of the blackout cloth of this product are smaller than the light-transmitting cloth. When the three layers of blackout cloth overlap, the light-transmitting part is larger than the blackout part, so a larger lighting range can be obtained, and the range of light brightness that can be adjusted is larger.
