The specific embodiment
Core of the present utility model is to provide a kind of sun blind, for make sun blind have good printing opacity, ventilation and defening effect simultaneously, and makes sun blind easy to clean or unpick and wash.
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Please refer to Fig. 1 and Fig. 2, the structural representation of a kind of sun blind that Fig. 1 provides for the utility model specific embodiment scheme; Fig. 2 is the syndeton schematic diagram between the utility model specific embodiment scheme Leaf.
In a kind of specific embodiment, the utility model provides following technical scheme:
A kind of sun blind, comprise blade 1, pelmet 4, be arranged at the rotating shaft 3 of blade 1 and the drag-line 5 rotating for controlling blade 1, blade 1 is connected in pelmet 4 rotationally by rotating shaft 3, rotating shaft 3 and the drag-line 5 rotating for controlling blade 1, blade 1 comprises slice, lower and two lateral plates, upper slice, lower forms the hollow cavity of wedgelike with two lateral plates, the tip of the hollow cavity of wedgelike is towards an outdoor side, upper slice be provided with for being connected the connector 8 of drag-line 5 for one end towards indoor of microperforated panel blade 1 with lower, drag-line 5 is connected in turn a plurality of blades 1 with connector 8.
