Abstract
Disclosed is a pin shaft winding wheel mechanism and a winding wheel system having an incomplete gear tilting mechanism for a window blind, wherein a winding wheel mechanism with a shaft pin comprises a base (38) and a top cover (39), a tilting cylinder (354) is provided between the base (38) and the top cover (39), a rotary shaft (357) passes through the tilting cylinder (354) and is mounted on a support seat (384) formed between the base (38) and the top cover (39), at least two push wheels (355) are fixedly connected on the hollow rotary shaft (357) inside the tilting cylinder (354), at least one winding wheel (351) is provided between adjacent push wheels (355), the winding wheel (351) is in a sliding connection with the hollow rotary shaft (357), at least one fan-shaped protrusion (3513) is provided on an outer ring of the winding wheel (351), wherein a hole (3512) is provided radially at one side of one fan-shaped protrusion (3513) and a pin hole (3551) is provided axially on a side edge of the outer winding wheel to make a pin shaft (356) pass through the pin hole (3551) and connect to two upper ends of a secondary ladder cord (8X) wound around the winding wheel outer ring. The secondary ladder cord (8X) is connected to a respective secondary blind slat (9X), an outer ring of the tilting cylinder (354) is provided with at least one annular groove (35X8) and a corresponding groove top part through-hole (3545) so as to enable the two upper ends of a main and the secondary ladder cord (8X) to be wound and nested therein while the secondary ladder cord (8X) enters the tilting cylinder (354) and is connected to the winding wheel (351). The main ladder cord (80) is fixed at the top part of the annular groove (35X8). A side edge of the push wheels (355) is provided with the shaft pin (356). The hollow rotary shaft (357) drives the rotation of the push wheels (355) and via the shaft pin (356) acts on the fan-shaped protrusion (3513) of the winding wheel outer ring to push the winding wheel (351) to rotate. The shaft pins (356) on each push wheel (355) are mutually spaced apart and provided with an angular difference, such that the winding wheels (351) are driven in turn thus raising in succession the respective secondary blind slats (9X) connected to the secondary ladder cord (8X) wound on the winding wheel (351). The winding wheel system having an incomplete gear tilting mechanism comprises the winding wheel mechanism with the shaft pin. The winding wheel system can control the lifting and tilting of the secondary blind slats (9X) and the tilting of main blind slats (90).
Description
technical field [0001] The invention relates to a variable-pitch combined louver, in particular to a reel system for the louver to control the lifting and turning motion of the louver blades. 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 is used to control the reel of the ladder belt. The rotating shaft passes through the rotary driver and the reel. A ladder belt is provided 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 lo...
