Problems solved by technology

[0002] The invention patent with the publication number CN102839909A has further improved the invention patent with the publication number CN101818616A, and proposed the concept of variable pitch shutters. The reel mechanism and reel system related to the variable pitch blinds have a characteristic that each reel is placed in a turning cylinder, and the upper ends of the ladder belts connected with the louvers need to surround the turning cylinder and extend into the turning cylinder. The hole at the top of the cylinder is fixedly connected with the reel. The disadvantage of this structure is that the ladder belt needs to be connected with the reel during the assembly process of the reel mechanism, and the assembly efficiency is low. Adjust the ladder belt at the pulley so that each group of louver blades is at the set initial horizontal position. Due to the above structural defects, this adjustment becomes more difficult

Embodiment 1

[0044] A time-sequence control reel system for variable-pitch blinds, which is used for double-divided variable-pitch blinds. In this kind of blinds, the louver blades are grouped in groups of four. figure 1 , Variable pitch shutters include top rail 1, drive shaft 2, timing control reel system 3, rope reel 3', driver 4, bead chain 5, side guide rail 6, lifting rope 7, main louver blades 90, secondary 100 blades 91, the second two hundred blades 92, the second three hundred blades 93, the main ladder belt 80, the second ladder belt 81, the second ladder belt 82, the third ladder belt 83 and the main bottom rail 100, the first bottom rail 101, the second second ladder belt The bottom rail 102, the third bottom rail 103, and the top rail 1 are equipped with a variable-pitch shutter transmission mechanism. The variable-pitch shutter transmission mechanism includes a drive shaft 2, more than 2 timing control reel systems 3, and 1 driver 4 and the connected bead chain 5 or rocker o...

Embodiment 2

[0049] Figures 4a-4d It shows a movement cycle of the horizontal lifting and turning of the upper and lower half of the louvers of the single two-point asynchronous variable pitch louver: (1) The main louvers are distributed on the window at equal intervals of 90, 90', and 90", Secondary louver blades 92, 93', 93" are superimposed on main louver blades 90, 90' and 90" respectively, (corresponding to Figure 4a ), (2) when the lower half of the second louver 92 rises to the middle position of the two main louvers 90 and 90', the upper half of the second three louver 93', 93" is still superimposed on the main louvers 90' and 90 " on (corresponding to Figure 4b ), (3) when the upper half of the third louver blade 93' rises to the middle position of the two main louver blades 90' and 90", the lower half of the second louver blade 92 is still on the two main louver blades 90 and 90' (corresponding to At Figure 4c ), (4) each main and secondary louver rotates from the horizont...

Abstract

The invention discloses a sequential control volume wheel system of a variable pitch window blind. The sequential control volume wheel system of the variable pitch window blind comprises a drive shaft, a half turnover cylinder mechanism used for controlling all louvre blades to overturn and a volume wheel mechanism used for controlling the louvre blades to lift relatively, wherein the volume wheel mechanism comprises a plurality of volume wheel sub-mechanisms; each volume wheel sub-mechanism comprises an overturning disc, a ladder belt winding bar and a ladder belt winding bar drive wheel set; the ladder belt winding bar is connected with the overturning disc in a rotating manner and is connected with the ladder belt winding bar drive wheel set in a transmission manner; the drive shaft passes through the overturning disc and is connected with the ladder belt winding bar drive wheel set in a transmission manner; the half turnover cylinder mechanism comprises a turnover sequential control sub-mechanism and a half overturning barrel, the drive shaft passes through the half overturning barrel and is connected with the turnover sequential control sub-mechanism in a transmission manner, and the overturning disc is arranged in the half overturning barrel.

Description

technical field [0001] The invention relates to a roller accessory of a shutter, more specifically, it relates to a timing control roller system of a variable pitch shutter. Background technique [0002] The invention patent with the publication number CN102839909A has further improved the invention patent with the publication number CN101818616A, and proposed the concept of variable pitch shutters. The reel mechanism and reel system related to the variable pitch blinds have a characteristic that each reel is placed in a turning cylinder, and the upper ends of the ladder belts connected with the louvers need to surround the turning cylinder and extend into the turning cylinder. The hole at the top of the cylinder is fixedly connected with the reel. The disadvantage of this structure is that the ladder belt needs to be connected with the reel during the assembly process of the reel mechanism, and the assembly efficiency is low. The ladder belt is adjusted at the wheel so tha...
