The utility model is achieved by the following technical solution: comprise some blades, stay cord and angle modulation line, some blades run through together online by stay cord, the stay cord both sides also are equipped with the angle modulation line of adjusting the blade flip angle, it also comprises dwang, track base and driver part in addition, the two ends of dwang are placed in the track base the inside, between dwang and the track base is to match, be provided with the driver part that the traction dwang rotates in the side of dwang end, the top of stay cord, angle modulation line is installed and is connected on the dwang.

The utility model also comprises structure of rolling, this structure of rolling comprises cover and spring in snap close overcoat, the snap close, the sealing of snap close overcoat one end, other end opening, cover is tucked into snap close overcoat the inside from the opening order in spring, the snap close, overlap in snap close overcoat, the snap close respectively that correspondence has hole and through hole, the afterbody of stay cord passes hole and through hole.

Above-mentioned described dwang can be semi-circular, also can be that semicircle is ring-like.

Cooperating between above-mentioned described dwang and the track base is closely to press together.

Above-mentioned described end in the dwang two sides respectively is provided with a driver part.

Above-mentioned described two driver parts can also can be distributed in two ends at the same end of dwang.

Above-mentioned described driver part can be a pull-rod, also can be rope.

Above-mentioned described track base end face is provided with installing hole.

Above-mentioned described track base outside also is equipped with the adjustment screw.

The utility model compared with prior art has following advantage: 1) by the cooperate function that can conveniently realize adjust blade lean angle of dwang with track base, simple in structure, number of parts is little, greatly reduces manufacturing cost; 2) dwang and track base designs simplification are installed easily, just can adjust the blade lean angle by pull-rod and rope, and be easy to use; 3) by using new structure of rolling, make the operation of folding and unfolding curtain easily simple more, further simplify the structure simultaneously, greatly reduce the cost of product, make easily simple.

5, the specific embodiment:

As Fig. 2, Fig. 3, Fig. 4, shown in Figure 5, the utility model comprises some blades 1, stay cord 2 and angle modulation line 3, some blades 1 run through together online by stay cord 2, stay cord 2 both sides also are equipped with the angle modulation line 3 of adjusting blade 1 flip angle, it also comprises dwang 4, track base 5 and driver part in addition, the two ends of dwang 4 are placed in track base 5 the insides, between dwang 4 and the track base 5 is to match, be provided with the driver part that traction dwang 4 rotates in the side of dwang 4 ends, the top of stay cord 2, angle modulation line 3 is installed and is connected on the dwang 4.Dwang 4 can be semi-circular, also can be that semicircle is ring-like.Cooperating between dwang 4 and the track base 5 is closely to press together, the end that is arranged on dwang 4 two sides respectively is provided with a driver part, and two driver parts can also can be distributed in two ends at the same end of dwang 4, driver part can be a pull-rod 12, also can be rope 13.Track base 5 end faces are provided with installing hole 14, and track base 5 outsides also are equipped with adjusts screw 15.

As Fig. 6, Fig. 7, shown in Figure 8, the utility model also comprises structure of rolling, this structure of rolling comprises cover 7 and spring 8 in snap close overcoat 6, the snap close, the sealing of snap close overcoat 6 one ends, other end opening 9, cover 7 is tucked into snap close overcoat 6 the insides from opening 9 orders in spring 8, the snap close, and snap close overcoat 6, the interior cover 7 of snap close correspondence respectively have hole 10 and through hole 11, and the afterbody of stay cord 2 passes hole 10 and through hole 11.In the time will packing up curtain, overcome spring 8 resistances and depress cover 7 in the snap close, make through hole 11 alignment on the cover 7 in the hole 10 and snap close on the snap close overcoat 6, stay cord 2 can be separated with structure of rolling, snap close overcoat 6 is up pushed away together, and it is just passable to tighten up stay cord 2, blade 1 is stacked in together, and is last, decontrols cover 7 in the snap close, spring 8 effect makes on the snap close overcoat 6 in the hole 10 and snap close on the cover 7 through hole 11 stagger down and tightens stay cord 2, and blade 1 is packed up.

Principle of the present utility model is: after installing, pulling pull-rod 12 or rope 13 make dwang 4 rotate around track base 5, make blade 1 along with dwang 4 upsets are tilted to a direction, because cooperating between dwang 4 and the track base 5 is closely to press together, between them, produce certain frictional force, when forwarding certain angle to, dwang 4 can be reliable stops and backward rotation more not.Make blade Reversion Level position, must spur another pull-rod 12 or rope 13 once more, make blade 1 along with dwang 4 overturns to counter-rotation, and the position that is up to the standard.When dwang 4 is semicircles when ring-like, dwang 4 has more elasticity, and cooperating between dwang 4 and the track base 5 is better, and rubbing action is better.
