Lift venetian blinds

Abstract

The invention discloses venetian blinds, wherein one end of an upper beam (11) is provided with a rope-locking device (13), the other end is provided with a side cover (9); the inside of an upper beam assembling system is provided with a cross shaft (12); a rope-locking device is arranged at one end of the cross shaft, the other end is assembled with a lifter; and a lifter component (10) is assembled by a lifter connecting base (16), a cloth ladder wheel brake shaft (17), a cloth wheel stop elastic device (18), a cloth ladder wheel (19), a bearing seat (20), a bearing (21), an elevating belt rotating wheel (22) and the like. The venetian blinds provided by the invention furthest solves the problem that rope holes on the strips of the blinds leak light; and the lifting belts can be freely retractable in the lifting or dropping process of the venetian blinds, the venetian blinds can not twist together, the operation is easy, convenient and labor-saving and has no noise, the track space is saved, and the venetian blinds of the electric motor is easy to hide.

Description

technical field [0001] The invention relates to a lifting type blind. Background technique [0002] Traditional venetian blinds are composed of venetian blinds, upper beams, lower beams, curtain lifting adjustment devices, curtain corner adjustment devices and other components. There are two holes on the venetian blind, and the lifting rope is passed through the two holes of the venetian blind, and the venetian blind is raised and lowered by operating the lifting and lowering rope to drive the metal worm and worm wheel; the venetian blind is adjusted by adjusting the corner rod. angle of rotation. When the venetian blinds are in a horizontal state, the venetian blinds are in a fully open state; when the venetian blinds are inclined at a certain angle to the horizontal line, the venetian blinds are in a half-open, half-closed or closed state. Because the venetian blinds are provided with holes, even if the venetian blinds are completely closed, the light leakage generated b...

AI Technical Summary

Problems solved by technology

[0004] This invention basically solves the problems of inconvenient adjustment and high cost of traditional venetian blinds. Compared with the previous venetian blinds, the light leakage from the holes of the venetian blinds is also reduced, but there are still some aspects that need to be improved. For example, the holes on the venetian blinds are still smaller. Large, there is still the possibility of light leakage; the connecting rope of the curtain is wound on the rope drum, and there is a possibility of knotting during the lifting operation, once knotted, it will seriously affect the use of the blinds; the friction between the connecting rope and the rope drum Large, not light enough to operate, and noisy during operation; the structure of the rope drum occupies most of the space in the upper beam assembly system, creating obstacles for the installation of motors in the upper beam assembly system to achieve further improvement of intelligent blinds
