Description

Technical Field

[0001] The utility model relates to the technical field of rolling shutter windows, in particular to a manual speed regulating mechanism for rolling shutter glass. Background Art

[0002] The rolling window has a beautiful and simple appearance and is suitable for shading windows in offices and homes, especially for rolling up large glass curtain walls. A rolling shaft is provided on the upper part of the rolling window, and the rolling cloth is opened or closed by driving the rolling shaft to rotate.

[0003] After searching, it was found that the Chinese utility model patent with the authorization publication number CN206386066U disclosed a blind with a variable speed rope reel. From its specification, it can be seen that the transmission ratio of the driving wheel 1 and the driven wheel 1 is greater than 1, which is a reduction transmission. The transmission ratio of the driving wheel 2 and the driven wheel 2 is less than 1, which is an acceleration transmission. When the driving wheel 1 is meshed with the driven wheel 1, the driving wheel 2 and the driven wheel 2 are not in contact; after the driving shaft slides to the left, the driving wheel 2 is meshed with the driven wheel 2, and the driving wheel 1 and the driven wheel 1 are not in contact. Thus, the speed adjustment is realized.

[0004] However, the Venetian blinds in the above patents have the following problems: (1) the speed change mechanism can only provide two rope winding speeds, and the speed adjustment range is small; (2) when adjusting the rope winding speed, it is necessary to first pull the driving shaft to move the driving shaft forward, and then rotate the driving shaft to achieve speed change, which is inconvenient to use; and the limit card is stuck in the limit groove of the rocker sleeve. When the rocker handle is rotated, the limit block will affect the rotation of the rocker sleeve. Moreover, when the rocker sleeve is rotating, when the limit block is separated from the limit groove, the rocker sleeve is no longer restricted, which makes it easy for the driving shaft to move, causing the driving wheel and the driven wheel to separate, and the rope cannot be retracted or released.
