Blind window reel system with planetary gear turnover mechanism

Abstract

The invention relates to a blind window, in particular to a reel system of a blind window. The invention provides a blind window reel system with a planetary gear turnover mechanism. The blind window reel system comprises a base and a top cover, wherein the base is provided with a reel mechanism and the planetary gear turnover mechanism; the reel mechanism comprises a turnover barrel; at least one reel is arranged in the turnover barrel; the turnover barrel is supported on the base through a hollow rotating shaft; and a planetary gear shaft of the planetary gear turnover mechanism is eccentrically arranged on a side edge of the turnover barrel. A square shaft drives the hollow rotating shaft to rotate, the hollow rotating shaft drives the reels in the reel mechanism to rotate, so that secondary ladder tapes fixed on the reels are wound or unwound, and various secondary louvre blades are sequentially driven to horizontally ascend or descend. When the various secondary louvre blades horizontally ascend to a set position, a locking effect of a torsional spring to the turnover barrel is relieved by the reels, so that the turnover barrel is driven to rotate, and turnover of all the louvre blades is realized. In a louvre blade turnover process, the turnover barrel drives the planetary gear shaft to rotate, and all the reels are connected with one another to form a whole; and when reverse turnover of all the louvre blades is realized, locking of the torsional spring to the turnover barrel is relieved by the planetary gear shaft, so that the turnover barrel is driven to reversely rotate.

Description

technical field [0001] The invention relates to a shutter, in particular to a roller system of the shutter. Background technique [0002] The traditional blinds are composed of louver blades with an arc-shaped cross section, lift ropes, ladder belts, top rails and bottom rails. A rotary drive with self-locking function, a rotating shaft, and several winding lifts are installed in the top rail. The rope and the reel of the ladder belt are controlled. The rotating shaft passes through the rotary driver and the reel. A ladder belt is arranged between the top rail and the bottom rail. The lower end of the ladder belt is fixedly connected with the bottom rail. On the reel, a plurality of louvers arranged in parallel are worn in the horizontal cable of the ladder belt. A perforation is set at the symmetrical center of the cross section of the louver to allow the lifting rope to pass through. The lower end of the lifting rope is fixedly connected with the bottom rail. The upper en...
