As shown in fig. 1-2, the utility model provides a blind, including a plurality of interconnect's curtain 1, a plurality of curtain 1 parallel arrangement, curtain 1 includes interconnect's first blade 11 and second blade 12, all is provided with self-cleaning layer on first blade 11 and the second blade 12, and first blade 11 is the obtuse angle setting with second blade 12, and the area of second blade 12 is greater than the area of first blade 11.

When the blind is closed, in two adjacent curtain sheets 1, the second blade 12 of one curtain sheet 1 can shield the first blade 11 of the other curtain sheet 1, so that no gap capable of transmitting light exists between the two adjacent curtain sheets 1, light cannot be irradiated into a room, and the shading effect is improved. Simultaneously curtain 1 not only can prevent that curtain 1 from discolouing along with the increase of illumination time through set up self-cleaning layer on first blade 11 and second blade 12, and self-cleaning layer can also play effects such as self-cleaning, deodorization, antibiotic moreover, helps improving the indoor air quality.

Optionally, the self-cleaning layer is selected as a titanium oxide coating, and the titanium oxide coating has the advantages of good thermal stability, no discoloration, no decomposition, no volatilization, no deterioration and the like at high temperature. Meanwhile, the titanium oxide coating can decompose bacteria under the irradiation of sunlight or ultraviolet rays, thereby achieving the antibacterial effect and playing the roles of preventing fouling, deodorizing and cleaning air. By arranging the self-cleaning layer on the curtain sheet 1, the color change or odor generation of the blind curtain along with the increase of the service time can be avoided.

In order to ensure that when the blind is closed, no gap capable of transmitting light exists between two adjacent curtain sheets 1, and incident light can be controlled by adjusting the angles of the curtain sheets 1. Optionally, the angle between the first blade 11 and the second blade 12 is set to 120-140 °. Preferably, the angle between the first blade 11 and the second blade 12 is set to 130 °.

Meanwhile, in order to enable the blind to be closed, the second blade 12 of one curtain sheet 1 can block the first blade 11 of the other curtain sheet 1 in two adjacent curtain sheets 1, and optionally, the area of the second blade 12 is set to be 2-3 times of the area of the first blade 11.

In order to facilitate the daily cleaning of the blind, the first vane 11 and the second vane 12 are each provided in a planar structure, and the first vane 11 and the second vane 12 do not have a convex-concave shape. When the blind is closed, the blind is flat and vertical, and dust is not easy to fall.

Alternatively, the side of the first blade 11 remote from the second blade 12 is provided with a chamfer, and the side of the second blade 12 remote from the first blade 11 is provided with a chamfer. The chamfer can play safety protection's effect, prevents that curtain piece 1 from cutting fingers etc. sets up the chamfer simultaneously and makes this blind more pleasing to the eye, and the aesthetic is down accorded with the time.

The blind further includes a lifting structure and a connecting structure. The lifting structure comprises a scroll component 21, a pulling rope 22 and a connecting rope 23, wherein the scroll component 21 can be fixed on external structures such as walls, the pulling rope 22 and the connecting rope 23 are fixed on the scroll component 21, a through hole is formed in the first blade 11, and the connecting rope 23 penetrates through the through hole to be connected with the plurality of curtain sheets 1. Wherein, reel subassembly 21 includes an iron set and rotary drum, and on the iron set was located to the rotary drum cover, stay cord 22 was the circulation rope, and on the both ends of stay cord 22 all were fixed in the iron set, the union rope 23 was fixed in on the rotary drum.

The connecting structure comprises two ladder ropes 31 and a plurality of transverse ropes 32, the two ladder ropes 31 are respectively arranged at two sides of the plurality of curtain sheets 1, and two ends of the ladder ropes 31 are respectively connected to the first curtain sheet 1 and the last curtain sheet 1. Specifically, both ends of one ladder cord 31 are connected to the first blade 11 of the first curtain sheet 1 and the first blade 11 of the last curtain sheet 1, respectively, and both ends of the other ladder cord 31 are connected to the second blade 12 of the first curtain sheet 1 and the second blade 12 of the last curtain sheet 1, respectively. Each transverse rope 32 is arranged below each curtain sheet 1, two ends of each transverse rope 32 are connected to two ladder ropes 31 respectively, each transverse rope 32 is fixedly connected with the corresponding connecting rope 23, the number of the transverse ropes 32 is the same as that of the curtain sheets 1, and each transverse rope 32 can play a supporting role for the curtain sheets 1. The pull rope 22 is pulled to drive the iron rod to rotate, so that the rotary drum is driven to rotate, the connecting rope 23 is wound on the rotary drum step by step or is scattered from the rotary drum, and the transverse rope 32 drives the two ladder ropes 31 and the curtain sheet 1 to move, so that the angle adjustment of the curtain sheet 1 and the folding and the putting down of the blind are realized. The pull rope 22 is pulled by a small amplitude, so that the angle of the curtain sheet 1 can be adjusted; the blind can be retracted or lowered by pulling the pulling rope 22 by a large amount.

Because the length of curtain piece 1 is longer, in order to make this tripe curtain atress balanced, seted up a plurality of wearing to establish the hole on every first blade 11, a plurality of wearing to establish the hole parallel and interval setting, it is provided with a plurality ofly to link rope 23, and a link rope 23 passes a wearing to establish hole on a plurality of curtain pieces 1 in proper order, and connection structure also is provided with the multiunit correspondingly, and multiunit connection structure parallel and interval setting, a plurality of horizontal ropes 32 and a link rope 23 fixed connection in every group connection structure. In this embodiment, each first blade 11 has 3 through holes, 3 connecting ropes 23 are provided, 3 rotating drums are correspondingly provided, and 3 sets of connecting structures are provided. Through pulling stay cord 22, the iron set is rotatory, and 3 tumblers are rotatory simultaneously, and 3 interlink ropes 23 drive curtain piece 1 motion simultaneously to the realization is to the angular adjustment of curtain piece 1 and the packing up of venetian blind and transfers.
