本发明涉及窗帘技术领域，尤其涉及一种内置遮光百叶窗帘。The invention relates to the technical field of curtains, in particular to a built-in shading blind.
背景技术Background technique
百叶窗帘通过在百叶窗帘片上设置通孔，将与下梁固定的升降拉绳穿过百叶窗帘片的通孔，通过驱动升降拉绳上升或下降可以实现百叶窗帘的升降；百叶窗帘的百叶窗帘片之间设有梯绳，通过驱动梯绳可以调节百叶窗帘片的转动角度。当百叶窗帘片处于水平状态时，百叶窗帘处于完全打开状态；当百叶窗帘片处于与水平线呈一定角度倾斜时，则百叶窗帘处于半开半闭或闭合状态。By setting through holes on the venetian blinds, the lifting rope fixed with the lower beam passes through the through holes of the venetian blinds, and the venetian blinds can be lifted and lowered by driving the lifting rope to rise or fall; the venetian blinds of the venetian blinds Ladder ropes are arranged in between, and the rotation angle of the blinds can be adjusted by driving the ladder ropes. When the blinds are in a horizontal state, the blinds are in a fully open state; when the blinds are inclined at a certain angle to the horizontal, the blinds are in a half-open, half-closed or closed state.
为遮挡住百叶窗帘片上的通孔产生的漏光，申请号为CN201420661347.6的中国发明专利公开了一种百叶窗帘叶片及百叶窗帘，该百叶窗帘叶片包括至少两个叶片孔，叶片孔布置于叶片的内侧；该百叶窗帘包括上梁轨道、梯带、叶片、升降拉绳、方向拉绳、下梁轨道，所述叶片设置有叶片孔，所述上梁轨道内安装有锁绳器和升降拉绳，所述升降拉绳依次穿过上梁轨道、百叶窗帘叶片的叶片孔和下梁轨道，且所述升降拉绳的一端固定在下梁轨道底端的尾扣处；所述升降拉绳的另一端穿过锁绳器从上梁轨道底端出口处连接拉绳连接器，所述叶片孔布置在所述叶片的内侧。该百叶窗帘叶片不漏光，叶片间的重复面积较小，成本降低，且看不见叶片间的升降拉绳，外表美观。In order to block the light leakage generated by the through holes on the venetian blinds, the Chinese invention patent application number CN201420661347.6 discloses a venetian blind blade and a venetian blind. The venetian blind blade includes at least two blade holes, and the blade holes are arranged in the blades The inner side of the venetian blinds; the blinds include upper beam rails, ladder belts, blades, lift ropes, direction pull ropes, and lower beam rails, the blades are provided with blade holes, and the upper beam rails are installed with rope locks and lift The lifting rope passes through the upper beam track, the blade hole of the blind curtain blade and the lower beam track in sequence, and one end of the lifting cable is fixed at the tail buckle at the bottom end of the lower beam track; the other end of the lifting cable is One end passes through the rope lock and is connected to the pull rope connector from the exit of the bottom end of the upper beam track, and the blade hole is arranged on the inner side of the blade. The venetian blind blades do not leak light, the overlapping area between the blades is small, the cost is reduced, the lifting and lowering ropes between the blades are invisible, and the appearance is beautiful.
然而，由于叶片孔偏置，在升降拉绳驱动百叶窗帘上升的过程中，随着百叶窗帘叶片在下梁轨道上堆积，升降拉绳下部的重心逐渐偏转，对于内置于中空玻璃中的遮阳产品，下梁轨道与百叶窗帘叶片将与中空玻璃内表面发生剐蹭或产生异响，甚至影响百叶窗帘正常的升降。However, due to the offset of the blade holes, the center of gravity of the lower part of the lift rope is gradually deflected as the blinds are piled up on the rail of the lower beam in the process of driving the blinds by the lift rope. For sunshade products built in insulating glass, The lower beam track and the venetian blinds blades will rub against the inner surface of the insulating glass or produce abnormal noises, and even affect the normal lifting and lowering of the venetian blinds.
